Philadelphia Eagles quarterback Jalen Hurts is expected to miss the remainder of the 2026 NFL season after being diagnosed with deep vein thrombosis and bilateral pulmonary emboli (blood clots in both lungs). Unfortunately, despite being a professional athlete in exceptional health, Jalen Hurts was a victim of a “perfect storm.” In week four of the NFL season, he suffered trauma to his calf (a muscle with a generous blood supply). He developed a hematoma (a localized collection of blood outside the blood vessels, often resulting in a localized “black and blue” mark). Then, he developed a superficial blood clot (not in the deep vein). He flew 7+ hours to London, played a football game and flew home. The clot moved from his leg, into the deep vein system and traveled to his lungs. This problem, especially when associated with flying (that alone is a risk factor for a DVT) does not only occur in athletes, but the public as well. But, with a little planning, you can minimize the risk!

Air Travel

Have you noticed that being in a car or on an airplane for more than three hours leads to soreness, stiffness and swelling in your legs and neck and back pain?  With a little planning, preventing or limiting these problems on long trips is possible. Also, as people age and/or develop other health problems, they are more vulnerable to developing a more serious problem associated with long trips; deep vein thrombosis (DVT) or blood clots. But problems with long-distance travel can be avoided. The following tips, based on research and personal experience, can prevent neck, back, leg pain, stiffness and DVT.

Deep Vein Thrombosis  (DVT)

A DVT is a blood clot that forms in a deep vein. The deep veins pass through the muscles and cannot be seen like the veins just under your skin. While it may occur in your arms, it is much more common in the legs, especially the calf muscle when traveling. When a blood clot forms in a leg vein it usually sticks to the vein wall. Often, pain and swelling lead you to the doctor and treatment is rendered before serious complications develop. However, there are two possible complications. One, a pulmonary embolus occurs when a part of the clot lodged in your deep vein of the calf breaks off and gets lodged in the lung. This is a very serious problem that can be fatal. Two, post-thrombotic syndrome, occurs when you have pain and swelling in your calf after a DVT.

Risk Factors for Travel Related DVT?

The following risk factors for DVT significantly increase the potential for problems when traveling on long trips by air, more than 5 hours. Trains, cars and buses also create a risk, but air travel creates a greater risk for the following reasons: reduced cabin pressure, reduced cabin oxygen levels, dehydration and alcoholic drinks, which may increase dehydration and immobility.

• Immobility - such as sitting on a plane slows down blood flow, especially in the legs.
• Genetic Blood Clotting  - inherited Factor V Leiden – relatively rare
• Contraceptive Pill – leads to increased blood clotting
• Hormone Replacement Therapy - leads to increased blood clotting
• Previous Vein Damage – such as a trauma, surgery or previous DVT
• Over 40 Years Old – DVT risk increases with age, especially associated with poor
• health
• Recent Surgery or Trauma– such as total joint replacement, hip fracture, trauma and hematoma
• Pregnancy – 1 in 1000 pregnant women will get a DVT
• Obesity – health and mobility risk
• Family History – increases risk
• Heart Failure – increases risk

Prevention of Travel Related DVT and Leg Pain/Stiffness

• Exercise - Keep your calf and foot muscles moving every 30 minutes which can be performed in your seat;
  • Heel Raises – push toes down and heel up
  • Toe Raises – lift toes up and heel down
  • Leg Kicks – extend leg up and down
  • Hip Hike – raise knee up 4-6 inches and down
• Compression Stockings – Wear elastic compression stockings when you travel on         
• long trips by air (or car, bus, train etc) and have risk factors
• Anticoagulant Medication – If you are at high risk of DVT your physician may discuss the use of medication to prevent clots. Sometimes, a simple aspirin may do the trick.         
• Walk – keep moving every 30-45 minutes…walk around the cabin
• Hydrate – Drink plenty of water, stay hydrated, and avoid alcohol

Prevention of Travel Related Neck and Back Pain

Airplane seats are “C” shaped and force you to round your neck and back forwards. These exercises are designed to stretch and extend your back in the opposite direction. Please perform slowly, hold for 3-5 seconds and repeat 10 times each hour.

• Chin Tuck: Tuck your chin back to bring your head over shoulders.
• Shoulder Blade Pinch: Pinch your shoulder blades together.
• Standing Extension: While standing, put your hands behind back and extend lower back 10-20 degrees.
• Bend Your Knees Up Toward Your Chest – one at a time
• Arch Lower Back Slightly

Sitting: When sitting in an airplane seat, take the neck pillow in the overhead compartment and place it in the small of your lower back. While sitting or standing up, perform postural exercises every 30-45 minutes.

Visit your doctor regularly and listen to your body.

It has been challenging and disappointing to be an Eagles fan so far this season! Losing two star players to hamstring injuries has not helped! Both Saquon Barkley and DeVonta Smith have been sidelined with hamstring injuries for weeks. One of the most common injuries associated with physical activity, especially after a sedentary winter or change in temperature is a “pulled hamstring.” This painful injury is not only for the weekend warrior. Well-trained, healthy and fit professional athletes often have their season interrupted for weeks and months due to a hamstring injury. What is the hamstring?  How is it injured? What is the best treatment?

Hamstring Strain

A hamstring strain is a tear of the muscle fibers of the muscle group in the back of the thigh called the hamstring. The hamstring muscle is a group of three muscles that run from the back of the hip (lower pelvis), crossing the back of the knee and attaches to the knee bone (tibia). The hamstring muscles work to extend the hip and bend the knee during running and walking activities. They are very active when an athlete changes direction, especially forwards and backwards or decelerating.

This injury, like others muscle strains, varies in intensity. Severe hamstring strain occurs when many muscle fibers are torn. The athlete may experience a sudden onset of severe pain in the back of the thigh and occasionally report a popping sensation. Pain, swelling and black and blue skin from tissue damage and bleeding is often reported. Also, pain is reproduced when attempting to bend the knee. In very severe cases, the boney attachment can be pulled so strongly that a small fracture can occur. Healing time can be as short as a few days or as long as weeks or even months.

The Most Common Causes of a Hamstring Strain

• Overuse – every time the knee is bent the hamstring muscles must contract. If there is not adequate time allowed for rest between workouts or competition, then the muscles may be fatigued and become vulnerable to injury. Also, overuse of the same muscles without rest may make them irritated and inflamed.
• Inadequate Warm-up – a warm muscle stretches like a piece of gum warmed up in your mouth. When you pull the warm gum, it stretches. However, if you drink an ice cold drink with gum in your mouth and then stretch the gum, it will tear instead of stretch. A good warm-up will prevent tearing and prepare the nervous system for sudden movements and changes in direction.
• Sudden Movement – quick sprint, sudden change in direction, quick turn with an unexpected force or slip.
• Muscle Imbalance – when the quadriceps (muscles in the front thigh) are disproportionately stronger than the hamstring muscles (muscles in the back of the thigh)
• Poor Body Mechanics – especially when moving or lifting a heavy load away from your center of gravity.
• Forceful Contact or Loss of Traction – when a leg is forced away from the body by an outside force (tackle in football) or slip on grass or ice.

Diagnosis

Your family physician will examine the back of your leg to determine if you have hamstring strain. Sometimes, pain in the buttocks and back of the leg can be referred from your lower back if the sciatic nerve is inflamed. In more advanced cases, you may be referred to an orthopedic surgeon for further examination and treatment. An X-ray, MRI or bone scan will show the extent of the tear and if the bone is involved. The diagnosis will determine if your problem is minor, moderate or severe.

Treatment

There are many conservative options. Your family physician or orthopedic surgeon will help you decide which choices are best.

• Anti-inflammatory Medications: such as aspirin, acetaminophen or ibuprofen to reduce pain and swelling. 
• Orthopedic Physical Therapy: such as heat, cold, ultrasound, electrical stimulation, joint mobilization, massage, range of motion exercises, strengthening exercises, and supportive compression strapping. Once pain free, a preventative training program is essential to prevent reinjury.
• Activity Modifications: if it is not the week of the district tournament, rest, avoid running or stretching/stressing of the thigh muscles.
• Supportive Devices: such as thigh wraps or sleeves, compression shorts (like those worn under basketball shorts) can provide compression and relief.

Prevention

Recent studies have determined that a training program specifically designed to prevent hamstring injuries is effective, especially for the competitive athlete. This program includes:

• High Intensity Training- regardless of the speed of your sport, high intensity, interval anaerobic training is critical. Interval sprints are the best example.
• Simulate the Demands of the Sport – when training, simulate the specific demands of your sport… “train the way you play.” For example, in football, the average play lasts 7-10 seconds. Therefore, sprint on a count from the line of scrimmage for 7-10 seconds. First, sprint in a straight line. Then, sprint and cut at 3-5-10 yards. Then, sprint, cut and spin. Then, sprint figure 8’s.
• Weight Train for Power and Strength/Weight Train for Speed and Endurance- traditionally, weight training is performed with high weights and low repetitions to increase power and strength and both arms or both legs are used at the same time. However, to prevent hamstring injuries, add a few sets of speed/coordination training by performing lifting with low weights and high reps. Also, alternate right and left legs to simulate normal walking speed.
• Weight Training Using Negatives/Eccentrics – weight training with a concentration on lowering the weight against gravity, not raising it.

• Exercise All Muscle Groups – of the lower body, not just the quads and hams. Include: Hip flexion, extension, abduction, adduction, internal & external rotation
  • Knee: flexion, extension
  • Ankle: flexion, extension, inversion, eversion
• Warm -Up: a pregame slow jog or exercise bike and/or massage to the area to warm up the muscles prior to activity.
• Stretching: Indian sit stretch, Hurdler stretch, Lying hamstring wall stretch 
• Strengthening Exercises: weight training for legs, including inside and back leg muscles, use weights or resistance tubing for leg curls and hip extensions.
• Agility Drills: figure 8, cross-over, tire or disc running
• Compression Shorts: like those worn under basketball shorts
• Cool Down: use ice to the effected area after exercise or sport

It seems like every time you scroll through social media wellness or fitness posts, there is a new “fad “or “craze” promising to enhance fitness and weight loss. Weighted vests seem to be the new favorite of social media influencers and fitness fanatics. A weighted vest is a form-fitting garment loaded with extra weight. The vest is worn over the torso during exercise or daily activities to increase resistance. However, like most fads, there is a gap between testimonials and scientific research. But, before you hit the trails with extra weight on your back, know the benefits and risks of using a weighted vest.

Weighted Vests (WV)

According to the American College of Sports Medicine (ACSM), weighted vests are an effective way to increase the calories burned while walking. When tested on untrained subjects, (ages 18-55 years) it was found that walking 2.5 mph while wearing a weighted vest of 15% of their body weight increased energy expenditure approximately 12% as compared to those not wearing a vest. Those subjects wearing 20% of their body weight while walking 3.0 mph expended 13% energy. Please note, however, that the recommended vest weight is 5-10% of body weight.

Potential Benefits of Using a WV– according to the current scientific literature

• Caloric Expenditure – as stated above, wearing a WV can increase caloric expenditure up to 12-13%.
• Bone Mineral Density – wearing a WV can increase mechanical axial load, (increasing the impact of gravity) to signal bone remodeling more than casual walking without a WV. However, those with existing osteopenia/osteoporosis should consult with their physician prior to using a WV.
• Cardiovascular Load – wearing a WV while walking or stair climbing has been found to elevate oxygen consumption and heart rate.
• Functional Strength – WV use while performing non-impact exercises (pull-ups, push-ups, squats, lunges) can improve functional strength.

Potential Side Effects/Risks of Using a WV

Some of the more obvious side effects of wearing a WV are; blisters, chafing, and muscle soreness and the risks of wearing a WV may require medical clearance from your physician or physical therapist if you have the following conditions:

• Chronic neck pain, middle and lower back pain…especially with radiating symptoms into the arms or legs.
• Osteopenia/Osteoporosis – bone density problems
• Balance or Vestibular Problems
• Arthritis – symptomatic arthritis in spine or lower extremities (hips, knees, ankles, feet)

Types of WV’s:

WV’s can be found online or in stores like Dick’s Sporting Goods, Target and Walmart.

• Plate Carrier Vest: Holds flat metal plates often preferred by those performing cross-fit or rucking (walking, marching, hiking while using a weighted backpack).
• Pocket/Plug Vest: Has small pockets to hold individual sand or iron-filled weights. This type of vest tends to be close-fitting and balanced. It allows for easy changes in the amount of weight.
• Fixed-Weight Vest: Offers an inexpensive, easy to use, pre-loaded vest for weighted exercise. However, this vest does not allow for variation in weight.

Choosing the Best WV:

Like most things, there is not one size and style that is best for everyone. WV’s vary in size, cost, durability, flexibility and adjustability.

• Start Light: Begin with a vest that allows variation in weight. Start with a light weight which should be approximately 5-10 pounds or 5% of your body weight. Weight can be added gradually over time but should not exceed 10% of your body weight.
• Maximum Weight: Although an adjustable WV allows a light start with gradual increases, it is recommended that users keep the amount of weight under 10% of their body weight for safety and the ability to maintain proper alignment and posture.
• Adjustable Weight and Straps: WV’s with the ability to adjust the amount of weight and the straps for a proper fit are recommended. A proper fit prevents blisters, chafing and back pain.

How to Begin Using a WV:

• Limit Load -start conservatively at 5% to 10% of your total body weight.
• Movement Safety – start with non-impact movement and activities such as walking, hiking, lunges, step-ups and avoid running or jumping.
• Proper Fit – a snug fit with adjustable weights and straps is best.
• Caution for Those with Pre-existing Risks – medical clearance is advised

In Conclusion:

What the Science Says – Using a WV can be an effective way to increase the calories burned while walking or performing other non-impact activities. WV can also improve bone density, cardiovascular fitness, and functional strength. However, for those with the aforementioned risks, medical clearance is advised.

Provisional Bag/First Aide Kit

It is one week away from the 29^th Steamtown Marathon. This column is dedicated to all the runners preparing for the big day. One small piece of advice; start slowly, avoid the first mile adrenaline sprint downhill, and enjoy the journey! Remember, only one Olympic marathon winner (Juan Zabala, Argentina, 1932) was in the lead at the 5 mile mark. Lesson: The last miles matter more than the first!

Today, I hope to address some common questions for the novice marathon runner or for those coming from other locations to run in the race. What should you pack? How should I dress? What supplies will I need?

Elite runners are so experienced that they know exactly what to pack in preparation for the big day. However, those, running in marathon for the first or second time usually have lots of questions. First, what you need and what you can bring will depend on your support team. If you are running alone and will not have family or friends meeting you along the way, then you are limited to a fanny pack and a few supplies. If you have a support team, then they can carry a bag with supplies, meet you along the course and you can have a sense of security.

Remember; do not do anything different on race day. Try out special clothing, water with supplements and snacks on a practice run. Also, experiment with your best pre-race meal. You will be getting up at 5-6:00am to catch the bus from Scranton to Forest City. You may want to pack breakfast to eat in the high school gym such as; bagel, peanut butter, jelly, banana and coffee or Gatorade. Moving your bowels before the race is a must.

Marathon Musts:

• Dress:
  • Columbus Day Weekend in NEPA could bring 30 to 40 degree temperatures when you catch the bus in Scranton and at the 8:00 am race starting time in Forest City.
• Clothing:
  • Hat and Gloves: Wearing a hat, light gloves can be a good idea. DryTech materials are best to prevent retention of sweat.
  • Long Sleeve Shirt and Light Jacket may be necessary. Wearing old items are best so they can be discarded along the way once you are warmed up.
  • Remember, any extra items can be placed in a labeled bag at the starting line and will be transported to the finish line for your convenience. So, if it’s a cold morning, wear a jacket and warm up pants on the bus to the starting line and “bag it!”
• Accessories:
  • Sunglasses and Sunscreen: If sun and warm temps are forecasted, sunglasses are best placed on top of your hat until needed and sunscreen applied before the race.
  • Skin Lubrication: Lubricate your skin with petroleum jelly in areas of potential friction such as arm pits, nipples, thighs and feet.
  • Dry Tech Clothing: Wear dry tech protects, including shirt, underwear and socks, to prevent excessive moisture and friction.
  • Favorite Water Source and Snack: Water and light snacks will be provided every 2 miles but sometimes it is good to have your own favorites, especially in the high school gym before the race.  

• FANNY PACK – Especially for those running without a support team
  • If you don’t mind the little pack on your butt, a fanny pack can be valuable. In it, you will want supplies such as: small bandages, small roll of medical tape, ibuprofen, antacid tablets, small tube of lubricant, favorite running snack, and extra shoe laces. One might also consider packing a little money, credit card, ID, emergency contact numbers and medical insurance cards. A cell phone is optional.
• SUPPLY BAG – For those with support team
  • Have your support team meet you at prearrange locations along the race route and bring your supply bag. In the bag, you might consider all of the above fanny pack items and: A change of clothes such as: extra running shoes, socks, shorts, shirt, water proof wind breaker, according to the weather, especially if rain is predicted.  Towels, ace bandages, gauze pads and wrap, antibiotic cream, mole skin, sunscreen, petroleum jelly, safety pins, extra water and favorite sport drink, favorite sport snacks, extra ibuprofen, antacid, anti diarrhea medicine, chemical ice pack, mobile phone, money, credit cards, ID, medical insurance cards.
  • For those with allergic reactions, remember to pack: epinephrine, antihistamine, and other important medications.

Don’t Forget: Map and directions to the bus or starting line, course map, race number, and get your timing chip.

Enjoy! Enjoy! Smell the roses, take in the fall foliage and chat with a fellow racer. Savor the marathon moment and enjoy the day…you are doing something very special!

Weight Training and Aerobic Exercise for GLP-1 Users

The popularity of glucagon-like peptide-1 (GLP-1) medications, such as semaglutide (Ozempic, Wegovy, Mounjaro) for weight loss, have increased exponentially over the past few years. Many medical experts predict that it is only the beginning. Medicare recently announced that it will begin a pilot program for those who qualify for GLP-1. If approved and covered by Medicare, GLP-1 use will become widespread. While the potential benefits of these weight-loss drugs exceed the risk for those suffering from obesity, it is not without some risk and side effects such as gastrointestinal problems and loss of muscle mass. Following a healthy diet and engaging in an exercise program to maximize the benefits and minimize the side effects from GLP-1 medications is necessary.

GLP-1

Glucagon-like peptide-1 (GLP-1) medications, when used for weight loss, reduce food cravings, increase fullness, slow digestion and control blood glucose. However, gastrointestinal (GI) side effects and maintaining muscle mass and energy levels are common concerns. These medications are designed to mimic the action of a natural hormone GLP-1, which is produced in the intestines after eating. This hormone regulates appetite, blood sugar levels and digestion. Ultimately, by slowing digestion, GLP-1 users feel fuller for longer periods of time.

A recent study published in Journal of the American Medical Association (JAMA) strongly recommends that people using GLP-1 medications eat more protein, consume smaller meals and snacks, avoid certain foods to reduce constipation, nausea and heartburn, stay hydrated, and engage in regular exercise including aerobic exercise and strength training to minimize muscle and bone loss.

Benefits of a Well-Designed Weight Training Program for GLP Users

• Increased Strength
• Prevent Loss of Muscle Mass & Bone Density
• Improved Performance in daily tasks and activities
• Improved Endurance
• Improved Injury Prevention
• Improved Mental Health
• Improved Overall Health & Wellness

Risks From Poorly Designed or Unsupervised Program

• Risk level increases if the program is not developed or supervised by a qualified professional for technique, safety, intensity and frequency
• Lower Back Pain – from poor technique and overload
• Muscle/Tendon Strain – from overuse and overload
• Tendonitis – from overuse and overload

How to Begin A Weight Training Program for GLP Users

• Primary Care/Family Physician – get medical clearance to make sure that you are not at risk, especially if you have medical issues such as heart disease, hypertension, diabetes.
• Orthopedic Physical Therapist – your doctor may think you would benefit from a few visits with an orthopedic PT to make sure your program is well-designed for your specific goals and your specific needs or activities (gardening, walking, golf, tennis)
•  Avoid Getting Competitive – it sets you up for injury! No Clean-Jerk, Overhead Press, Full Squats. Don’t compete to lift to your maximum. Make Exercise FUN!
• Technique
  • Slowly lift and lower weight 4 seconds up, 4 seconds down
  • Breath – inhale lifting weight up and exhale down
  • Never hold breath!
  • Exercise Major Muscle Groups
  • Upper body: shrugs, rows, lats, biceps, triceps, chest press, wrist curls – all with light dumbbells and bands to start
  • Lower Body: hip hike, leg extension, ham curl, step ups, 45 degree squat, calf raise – all light with sandbags and dumbbells to start
• Lift 3 times per week on alternating days – 30 to 45 minute sessions
  • Warm up
  • Cool down
  • Work upper body/lower body
  • Can alternate days for upper body and lower body
  • INCLUDE AEROBIC EXERCISE:
  • Can alternate days for weight lifting with aerobic exercise (elliptical, swim, walk, run, bike)
• Concentrate on low weights (5-10#)/high repetitions(10-15 times)
  • Once you master the technique add 1-2 # and 3-5 reps
  • Never advance weight or reps if you overstrain and compromise technique

**STOP:

• If you have pain
• If you get lightheaded or dizzy
• If you experience lower back pain or joint pain
• If you have muscle or joint pain that lasts more than 2 days

GLP-1

Glucagon-like peptide-1 (GLP-1) medications, when used for weight loss, reduce food cravings, increase fullness, slow digestion and control blood glucose. However, gastrointestinal (GI) side effects and maintaining muscle mass and energy levels are common concerns. These medications are designed to mimic the action of a natural hormone GLP-1, which is produced in the intestines after eating. This hormone regulates appetite, blood sugar levels and digestion.

Diet and Nutrition Considerations for GLP-1 Users

FOOD TO AVOID

1. High-Fat Foods
   • High-fat foods can increase nausea and bloating.
   • Fried foods: French fries, fried chicken, and doughnuts.
   • Fatty Meats: Bacon, sausage and fatty meats
   • Creamy Sauces and Dressings
2. Sugary Foods and Beverages
   • Foods with high sugar content can spike blood sugar levels which counteracts the benefits of GLP-1 medications without significant nutritional value. Some include candy, sweets, pastries, desserts, sodas, sweet teas, fruit juices which can also contribute to GI issues.
3. Starchy Vegetables and Fruits
   • Some starchy vegetables and fruits have a high glycemic index which causes spikes in blood sugar. However, due to the nutritional value that this food group provides, moderation, not elimination, is the best approach when eating potatoes, corn, and peas. High sugar fruits such as very ripe bananas, mangos, and grapes must be consumed prudently.
4. Highly Processed Foods
   • Highly processed foods are never a healthy choice and more so for GLP-1’s. They often contain unhealthy fats, sugars and preservatives that can contribute to side effects. Some examples are; fast foods, prepackaged snacks (chips, cookies), and instant meals.
5. Alcohol
   • Overuse of alcohol can contribute to GLP-1 side effects…so drink in moderation and discuss it further with your physician.

Alternative Food Choices for GLP-1 Users

While it is important to eliminate unhealthy foods from your diet as previously discussed, it is equally important to include a diet rich in nutritious and wholesome foods to prevent the loss of muscle mass associated with GLP-1 use.

1. Lean Proteins
   • Chicken, fish, and plant-based proteins such as lentils, chickpeas, and tofu.         
2. Non-Starchy Vegetables (low in carbohydrates and calories)
   • Leafy Greens (spinach, kale, Swiss chard)
   • Cruciferous Vegetables (broccoli, cauliflower, Brussels sprouts)
   •  Colorful Vegetables (bell peppers, tomatoes, zucchini)
3. Whole Grains
   • Brown rice, quinoa, oats
4. Healthy Fats (good for your health and long-lasting satiety)
   • Avocados, nuts and seeds, olive oil
5. Hydration
   • Water is the first and best option for hydration in GLP-1 users. Other options include; herbal teas, infused water with fruits and herbs.

Tips for Maintaining a Balanced Diet for GLP-1 Users

1. Portion Control – GLP-1 medications reduce hunger. Eat smaller, balanced meals.
2. Be Mindful - Listen to your body - stay focused and listen to your body…don’t eat if you’re not hungry. GLP-1’s will make you feel full if you are paying attention.
3. Regular Meal Times – try to eat meals at consistent times to avoid blood sugar spikes.
4. Consult with a Dietitian – get professional advice from a registered dietitian to tailor a plan for your specific needs.

PART III OF III

This is the third of three columns dedicated to healthcare for college students. Please find these “10 Tips to Keep Yourself Healthy in College” helpful. However, no discussion regarding the health and wellness of college students would be complete and thorough without addressing what health care and university experts consider the two most dangerous behaviors on college campuses across the nation: binge drinking and unprotected sexual activity.

While it is not my intent to offend the religious and moral values of any reader, it is my purpose to provoke direct and meaningful conversation between parents, religious leaders and students. To prevent serious health problems in college, parents must share their experience and discuss their values regarding sexual activity and alcohol consumption with children before they leave home to live independently in college. If you are unable to have a direct conversation about these issues, consider doing what several readers have done; mail a copy of this column to your child!

10 Tips to Keep Yourself Healthy in College: (American Academy of Pediatrics)

• Sleep – somehow, despite a busy academic and social schedule, you MUST get enough rest. Lack of sleep may be the single unhealthiest habit of a college student. It can lead to many negative consequences such as lack of concentration, poor emotional stability, and vulnerability to germs and disease. While one may get by on 3-4 hours sleep for short periods of time, eventually, your body will take control and shut down. Do your best to develop a regular sleep pattern and factor in short naps to catch up on needed rest if necessary.
• Diet – the “freshman fifteen” is no joke, it is the real thing. Skipping breakfast, “pigging out” on junk food, late night eating, and drinking high calorie soda and beer all factor into weight gain and poor dietary habits. Make time to eat breakfast, snack on yogurt, fruit and nuts. Fill up on a healthy salad. Avoid a constant diet of fried foods and sweets.
• Water – even adults forget to drink plenty of water throughout the day. Carry a water bottle and skip the soda.

• Get regular check-ups – see your doctor when home on semester break for an annual check-up or more often if needed. Many college health centers offer this service. Many serious problems can be avoided with early detection.
• Get a flu shot, vaccines and mask up – remember, college campuses breed germs and most schools offer inexpensive flu shots and Covid vaccines. 
• Exercise – make time to exercise regularly (30-45 minutes 3-5 days per week). Walk, run, bike, lift weights, play tennis, racquetball or swim. Colleges have the best facilities for sports and exercise. Just DO SOMETHING! It will help you sleep, relax and feel better.
• Relax – make time to relax. Read a book, go for a run, meditate, do yoga, or walk and have good conversations with friends. Mental health is important on a stressful college campus.
• Emotional Health – is a vital component of a healthy person. College life can be very stressful. Depression, anxiety, addiction, eating disorders, and homesickness are some examples of emotional problems common among college students. If you feel emotionally unhealthy, get professional help. All colleges have trained counselors equipped to assist you. 

• Drink Sensibly – binge drinking might be one of the most dangerous behaviors on a college campus. Studies show 44% of U.S. College students engage in binge drinking uniformly among freshman through seniors. Of these, 50% binged 3-4 times in a two-week period. Binge drinking is defined as 5 drinks in a row for men and 4 for women. Binge drinkers are more likely to be victims of poor academic performance, addiction, trauma, auto accidents, assault, unprotected sex, sexual assault, and death. Some of the most common reasons reported for binging are: to get drunk, status, campus culture, peer pressure, academic stress. TALK TO YOUR CHILDREN!
• Safe Sex – promiscuous sex is physically and emotionally unhealthy. Unprotected sex can be LIFE ALTERING! Studies by the Center for Disease Control found that almost 80% of college students 18 to 24 years old had sexual intercourse at least one time during college. 73% reported having unprotected sex and 68% of this group did not believe that they were at risk of contracting a sexually transmitted disease. TALK TO YOUR CHILDREN! GET THE HPV VACCINE!

Education, Medication, Diet, and Exercise

The list of diseases such as high blood pressure, diabetes, and stroke that can be managed, cured or prevented is endless. Certainly, cholesterol and heart disease are at the top of the list. Studies clearly demonstrate that managing cholesterol through education, medication, diet and exercise can significantly reduce the risk of heart disease.

Education –

Know your numbers. Learn the difference between unsaturated and saturated fats. Make yourself a student of healthy living through diet and exercise. Avoid fads and focus your effort on scientifically proven methods. Many experts feel that those with genetically high cholesterol should use exercise and diet to maintain health but will also need require the addition of a statin drug to manage cholesterol effectively.

Statin Drugs -

There are many methods to lower your LDL (bad cholesterol). However, no method has been proven more successful than statin drugs. Multiple landmark studies confirm that for those individuals needing statin drugs to control their cholesterol, the benefits far outweigh the risks.

By inhibiting an enzyme in the liver, statin drugs limit the liver’s ability to produce cholesterol thereby significantly lowering LDL (bad cholesterol) and triglycerides and modestly increasing HDL (good cholesterol). As a result, their unique benefits include preventing and reducing plaque in arteries, stabilizing existing plaque, reducing inflammation of the arterial wall, and improving overall vascular function. Statin Drugs Include: Lipitor (atorvastatin); Lescol (fluvastatin); Mevacor (lovastatin); Pravachol (pravastatin); Zocor (simvastatin); Crestor (rosuvastatin).

Clinical studies that have shown that statin drugs significantly reduce the risk of heart attack and death in patients with proven coronary artery disease (CAD) and can also reduce cardiac events in patients with high cholesterol levels who are at increased risk for heart disease. And although statins are best known for lowering cholesterol, they may also have several other benefits: they may prevent Alzheimer’s disease, and they may also have a positive impact on diabetes and blood pressure.

Exercise –

Second only to statin drugs, no other method of the prevention of CAD has proven more effective than exercise, specifically aerobic exercise. It is well documented that physically active people have a lower incidence of CAD than sedentary people. For the prevention of CAD, the following exercises are defined as aerobic: High Amount/High Intensity – a caloric equivalent of jogging 20 miles per week at 65 -80 percent intensity, Low Amount/High Intensity – a caloric equivalent of jogging 12 miles per week at 65 to 80 percent intensity, Low Amount/Moderate Intensity – a caloric equivalent of walking 12 miles per week at 40 to 55 percent intensity.

Exercise is a valuable prevention tool on many levels: it reduces weight, LDL, and blood pressure, and it increases HDL. Research has found that the amount of exercise matters more than the intensity. For example, those exercising 5 or more days per week benefited more than those exercising less often. However, it is important to remember that ALL exercise groups showed improvement.

Diet –

Following a Mediterranean diet is one way you can reduce CAD and cut your risks for other diseases. While no Mediterranean diet has more value than another, the following equation highlights the factors that make a Mediterranean diet so valuable. First, eat a variety of fruits, vegetables, whole grains, beans, nuts, and seeds, with olive oil as an important source of fat. Then, add moderate amounts of fish, poultry and fresh dairy. Finally, subtract red meat from your diet, or at least limit your consumption.

The Dietary Approaches to Stop Hypertension (DASH) diet is the American version of the Mediterranean diet and has been found to reduce blood pressure and LDL levels. It is rich in fruits and vegetables, moderate in low-fat dairy, and low in animal protein. It promotes the use of legumes and nuts as plant sources of protein.

Along with increasing your plant-based foods and decreasing your consumption of red meat, you may also want to replace some of the carbohydrates in your diet with proteins or monounsaturated fats. This switch can improve lipid levels.

Fiber, Nuts, Tea, and Alcohol –

Dietary soluble fibers such as pectin, wheat dextrin, and oat products will reduce LDL. Some suggest that a combination of soluble fiber with plant sterols may be beneficial. Walnuts, high in polyunsaturated fatty acids, have been shown to positively impact serum lipid levels. Almonds, pistachios and other nuts have shown similar results. Those consuming nuts more than four times per week showed the most significant improvement. Also, those with moderately high LDL who drank green tea once to twice per day while following a low-fat diet found more improvement in LDL reduction than they did with a placebo. Moderate alcohol consumption (1-2 drinks per day) has been shown to improve HDL levels. Red wine has the added antioxidant benefit even in its non-alcohol form. 

Weight Loss –

Fat cells secrete chemicals that negatively affect lipid metabolism. “Maintaining a body that is slim and trim with consistent exercise and a low-calorie diet limited in saturated fats is the key”

Supplements –

While the internet is littered with information on thousands of supplements claiming to lower cholesterol and provide other life enhancing outcomes, few are proven effective. Of these, only fish oil, taken in concentrated high doses (> 6g/day) has been proven to lower triglycerides and LDL.

Multivitamins, soy proteins, and other grain products, while not cholesterol reducing, are valuable to many. But when it comes to reducing cholesterol, garlic, policosanol, Vitamin E, and isoflavone supplements have failed the scrutiny of scientific research. Plant sterols such as Benecol^R sisosterol and campesterol, found in Promise activ^TM, have been shown to slightly reduce serum cholesterol levels; however, no studies have demonstrated their ability to lower the incidence of CAD. In fact, the Nutrition Committee of the American Heart Association has suggested that the general population not use these products until further studies determine their safety and efficacy, due in part to potential side effects.

It’s peak summer time … so make time to get to the water! Research shows that spending time outdoors has many positive effects on your health. Moreover, new research has found that being near a body of water makes us calmer and healthier. You know that special feeling you get when you drive to the lake or the beach and jump out of the car and smell the fresh air and hear the sound of splashing in the lake or the waves of the ocean? Well, it is not just because you’re on vacation…the water makes your muscles relax and breath deeper. Your brainwaves slow down to simulate the gentle roll of the water…lake or ocean! These “blue environments,” not to be confused with “blue zones” are the subject of extensive research at the University of Exeter Medical School in the UK.

Time spent near water promotes physical activity, general fitness and well-being. It is also associated with reducing the incidence of diabetes and other diseases associated with obesity. Additionally, time near the water slows down our heart rate, reduces stress hormones and improves mental health. In fact, the study also found that subconsciously, people consistently preferred pictures of natural environments (rivers, lakes, oceans) even when compared to attractive urban landscapes. In fact, urban landscapes with water (rivers, fountains etc) were far more popular than those without. And, health disparities between coastal and inland communities are more noticeable for low-income individuals who do not have the means to venture to the coast. This may be one of the reasons that four out of the five “Blue Zones” discovered by Dan Buettner are islands.

WHY BEING IN, ON, OR AROUND THE WATER IS HEALTHY:

• WATER STIMULATES ALL 5 SENSES
  • Water provides a totally immersive experience.  We feel the coolness trickling on our skin, we taste the salt, smell the seaweed, hear the waves and splash of the water, and see the sun glistening on the water.
• WATER STIMULATES OUR NERVOUS SYSTEM
  • Water impacts our physiology in that it triggers our parasympathetic nervous system to lower heart rate and blood pressure which promotes relaxation. Even the act of drinking a glass of water can promote relaxation and wellness.
• WATER IS BLUE…BLUE IS THERAPEUTIC
  • If the rolling blue waves in the lake and ocean aren’t enough, the blue light waves will work to promote further relaxation. Additionally, the beautiful backdrop of a blue sky is the icing on the cake to make you chill out!
  • Similar to “white noise” used by millions of parents to promote sleep for infants and toddlers, “pink noise” (the noise associated with natural sounds) is more smooth, soothing, ongoing and natural as it reduces brain wave activity…have you ever experienced a “beach nap?”
• WATER STIMULATES OUR INNATE BIOPHILIA
  • The biologist and naturalist Edward Wilson coined the term “biophilia” to describe the theory that humans have an instinctive bond with nature. As a species, our origins have begun on open savannahs and endless shorelines. These natural environments instinctively return us to a simpler time and place.

• WATER IMMERSION BALANCES OUR HORMONES
  • Did you ever notice the inner harmony of swimming underwater or total floating? When you are doing these activities, your body sends signals to balance stress hormones similar to the bodies response to meditation or relaxing.
• WATER ACTIVITIES STIMULATE ENDORPHINS
  • Whether you are swimming, surfing, kayaking, paddle boarding, fishing, clamming, walking the shoreline, digging a water hole or making a sand castle, these activities will stimulate endorphins. These natural chemicals have been associated withhappiness, pain management and overall well-being.

In addition to the benefits of being by a body of water, just being outdoors promotes better health and wellness:

• Nature’s Vitamin D – Current research suggests that Vitamin D (The Sunshine Vitamin), may offer significant disease prevention and healing powers for osteoporosis, some forms of cancer and heart disease. Of all the methods of getting an adequate amount of Vitamin D, none is more fun than spending time outdoors in the sunlight.
• Increase Activity Level – While exercising indoors in a gym is valuable, research shows that time spent indoors is associated with being sedentary and being sedentary is associated with obesity, especially in children
• Improved Mental Health – It is well documented that light affects mood. So, unless you live in a glass house or a light box, getting outdoors is important to your mental health.
• Improved Concentration – Richard Louv, author of the book, “Last Child in the Woods,” coined the term, nature-deficit disorder.” This term is supported by research that found children with ADHD focus better when outdoors.
• Improved Health and Healing – Researchers at the University of Pittsburgh found that patients recovering from surgery recovered faster with less pain and shorter hospital stays when they were exposed to natural light.
• Improved Breathing – In general, breathing fresh air is good for you. Some exceptions might be those with severe allergy problems when the pollen count is high. Despite this, it may be better to take allergy medicine and enjoy the benefits of being outdoors than to be stuck inside.

Have Fun and Get in Shape!

Happy 4^th of July! As our country celebrates 250 years and the summer heat is kicking into gear, it is time to think about getting to the pool to cool off. It may also be time to think of your pleasure puddle in different light…a health spa! It may very well be the exercise of choice for many people. Many have discovered the benefits of moving their limbs in the warm water of a home pool following knee or shoulder surgery. Also, long distance runners who often look for cross training methods without joint compression and arthritis sufferers who are often limited in exercise choices by joint pain from compressive forces when bearing weight, can enjoy the buoyancy effects of water. These are good examples of the benefits or water exercise…aerobic and resistive exercise without joint compression.  

Exercise and Arthritis:

Most doctors recommend some form of exercise with arthritis. Pain and fatigue are the most limiting factors for a person with arthritis. Pool exercise may be the answer. With proper technique, adequate rest periods, appropriate resistance and repetitions, water exercise can be very effective.

Pool Exercise Benefits:

The following are some of the benefits of water exercise:

• Decreased Risk of Cardiovascular Disease
• Improved Endurance
• Improved Strength – with resistance of water to exercise muscles
• Improved Flexibility and Range of Motion – with less pain
• Improved Function in Daily Activities
• Maintain Mobility
• Improved Balance
• Slow Down Osteoporosis
• Weight Control – which leads to less stress on joints
• Improved Mood and Attitude – release of endorphins and serotonin
• Improved Circulation – especially in warm water
• Decreased Muscle Spasm and Tension – especially in warm water
• Decreased Stress on Joints – Buoyancy effect of water

Getting Started:

• Medical Clearance – see your family physician for clearance especially if you have a cardiac history or joint replacements. Do not use pool if you have surgical sutures or an open wound.
• Warm Pool -  83-88 degrees Fahrenheit
• Water Walking Exercise– begin in shallow end
• Water Running Exercise– with buoyancy vest in deep end
• Water Aerobics Exercise– using arms and legs as in regular aerobic exercise but in the water
• Strength & Flexibility Exercise – just as on land but in water

• Start Slowly – Don’t Overdo it
  • 5-10 minutes and repetitions first time and add 2-3 minutes/repetitions each week
  • Long Term Goal: 20 – 40 minutes per session
    • 3-4 times per week          
• Submerge The Body Part
  • That you want to exercise into the water and move it slowly
• Complete The Range of Motion
  • Initially 5 times, then 10-15-20-30 times
• Assess
  • Determine if you have pain 3-4 hours after you exercise or into the next day. If so, you overdid it and adjust next time by decreasing repetitions, speed, amount and intensity of exercise.
• Warm-Up
  • Make sure you warm up slowly before exercise with slow and easy movements
• Advance Slowly
  • By adding webbed gloves, weighted boots, and buoyant barbells to increase the resistance.
• Exercises – standing in shallow end of pool
  • Heel Raises – push toes down and heel up
  • Toe Raises – lift toes up and heel down
  • Leg Kicks – extend leg up and down
  • Hip Hike – raise knee up 4-6 inches and down
  • Leg Squeeze – squeeze knees together and apart
  • Leg Curl – bend knee
  • Torso Twist – slowly turn arms/torso to right, then to left
  • Shoulder Forward and Backward – like paddling a boat
  • Shoulder Out and In – like a bird flying
  • Bend Elbow Up and Down

Visit your doctor regularly and listen to your body.
