This column is repeated every year at this time with the intent of raising the level of awareness to prevent death or serious illness from heat stroke in athletes and other active people in hot, humid weather.
It is the end of July and we have managed to survive two “heat waves” in NEPA. While it is important to have fun in the sun, please be mindful of how your body reacts to high humidity and heat and take appropriate precautions. Athletes are particularly vulnerable this time of year due to daytime practice sessions. (August 5 & 6, 2024, first day of acclimatization and August 12, 2024, first day of practice for fall sports according to PIAA). Visit www.piaa.org for more information. Keep in mind, you don’t have to be running a marathon or playing football in full uniform to suffer from heat stroke.
Heat stroke, one of the most serious heat-related illnesses, is the result of long term exposure to the sun to the point which a person cannot sweat enough to lower the body temperature. The elderly and infants are most susceptible and it can be fatal if not managed properly and immediately. Believe it or not, the exact cause of heatstroke is unclear. Prevention is the best treatment because it can strike suddenly and without warning. It can also occur in non athletes at outdoor concerts, outdoor carnivals, or backyard activities.
Some “old school” folks think that wearing extra clothing and “breaking a good sweat” is an optimal goal for exercise. However, it may be potentially very dangerous in hot and humid conditions. When exercising in hot weather, the body is under additional stress. As the activity and the hot air increases your core temperature your body will to deliver more blood to your skin to cool it down. In doing so, your heart rate is increased and less blood is available for your muscles, which leads to cramping and other more serious problems. In humid conditions, problems are magnified as sweat cannot be evaporated from the skin to assist in cooling the body.
The American Academy of Pediatrics and The American College of Sports Medicine has the following recommendations which are appropriate for both the competitive athlete and weekend warrior:

The 27th Steamtown Marathon is three months away and, despite the warm weather, many local runners are deep into training. With serious heat waves of summer, any prolonged endurance activity in minimal to moderate heat can be dangerous if not prepared. Adequate hydration is critically important, not only to those training for a marathon but also for other outdoor endurance activities such as cycling, hiking, long distance power walking, etc
Next to oxygen, water is the nutrient most needed for life. A person can live without food for a month, but most can survive only three to four days without water. Even though proper hydration is essential for health, water gets overlooked as one of the six basic nutrients. Dehydration occurs when the amount of water taken into the body is less than the amount that is being lost. Dehydration can happen very rapidly (i.e. in less than eight hours); the consequences can be life threatening and the symptoms can be alarmingly swift.
In the body, water is needed to regulate body temperature, carry nutrients, remove toxins and waste materials, and provide the medium in which all cellular chemical reactions take place. Fluid balance is vital for body functions. A significant decrease in the total amount of body fluids leads to dehydration. Fluids can be lost through the urine, skin, or lungs. Along with fluids, essential electrolytes, such as sodium and potassium, are also perilously depleted in a dehydrated individual.
The risk of dehydration is not limited to endurance athletes and outdoor enthusiasts. Dehydration is the most common fluid and electrolyte disorder of frail elders, both in long term care facilities and in the community! Elders aged 85 to 99 years are six times more likely to be hospitalized for dehydration than those aged 65 to 69 years.
Is water adequate to prevent dehydration? Will a sports drink improve my performance? While some answers to these questions apply generally to all, others vary according to the temperature, humidity, length of time and intensity of the activity and condition of the athlete.
Proper hydration is essential for the comfort and safety of the recreational and serious athlete. Hydration is critical to maintain cardiovascular function, body temperature and muscle performance. As temperature, humidity, intensity, and duration of exercise increase, so too does the importance of proper hydration. Excessive sweating can lead to a loss of blood volume which requires the heart to work much harder to circulate you blood through your body.
Dehydration is a major cause of fatigue, loss of coordination, and muscle cramping leading to poor performance. Prehydration, (drinking before exercise) is the first step in preventing dehydration. Marathon runners, other long-distance runners, and cyclists often prehydrate1-2 days before a big event. Rehydration, (drinking during or after exercise) is the second step in preventing dehydration. While athletes may be more vulnerable to dehydration, all persons engaging in exercise would benefit from increased performance, delayed muscle fatigue and pain by maintaining adequate hydration. Proper prehydration would include drinking 12-16 ounces of water 1-2 hours before exercise. Athletes with other health issues should consult their family physician before engaging in long distance endurance sports.

JUNE IS GREAT OUTDOORS MONTH! AS WE KICK OFF SUMMER AND CELEBRATE THE FOUR OF JULY, MAKE TIME TO GET THE HECK OUTSIDE! Research shows that spending time outdoors has many positive effects on your health. While there are many year-round activity options, in Northeastern Pennsylvania our short-lived summer is the inspiration to “suck the marrow out of a sunny day!” Summer in NEPA is enjoyed in many ways such as walking, running, hiking, biking, horseback riding, boating, kayaking, and swimming. Studies show that even less vigorous activities such as fishing, picnicking camping, barbequing, or reading a good book on the porch are healthier than being indoors.
It is reported that Americans spend 90% of their lives indoors and that number increases with age. Worse yet, for some, venturing outdoors is considered risky behavior with fear of the sun, ticks, wind, mosquitoes, and other creatures of God. Well, the truth of the matter is the risk of being one with nature is far less than the ill effects of a life stuck indoors. Please consider the following benefits of spending time outdoors.

Spring is here! So, too, is allergy season and spring sports! It seems this every year at this time a young little league baseball player wheezes as they cross home plate and desperately tries to catch their breath. Players, coaches, umpires, parents watch in dismay, deciding whether they need to call an ambulance. Minutes later the player recovers from this scary situation…until the next time. Could this be an example of exercised-induced asthma (EIA)?
Dr. Gregory Cali, a local pulmonologist, (lung doctor) was gracious enough to participate in an interview about this problem…exercise-induced asthma (EIA). The topic was chosen in response to an email question from a concerned mother of an athlete with asthma. Dr. Cali informed me that the first thing to know about exercise induced asthma (EIA) is that EIA is not a distinct disease in itself-but is one manifestation or presentation of asthma. Putting it simply, EIA occurs in patients who have develop narrowing of the bronchial tubes ( bronchoconstriction) when they exercise. Some experts would rather we use the phrase exercise induced bronchoconstriction which is what happens when someone has an asthma attack. This bronchoconstriction occurs because of spasm of the tiny muscles of the airways, plugging of the airways with thick mucous, and swelling or edema of the cells lining the airways.
In fact, it is inflammation of the airways, mostly due to allergies, that is at the root of most cases of asthma. This inflammation causes the bronchial tubes to become over-reactive-and predisposed to narrowing- when exposed to certain triggers. Exercise is one of those triggers in susceptible people. The patient with EIA complains of chest tightness, wheezing, and shortness of breath when exercising. Some patients only experience coughing with exercise. Symptoms are usually worse in cold, dry air. This is believed to be due to the drying and cooling of the airways, which occurs with exercise, especially if the patient opens his or her mouth while exercising. Nasal breathing is much better at warming and humidifying air and may help to reduce EIA.
Dr. Cali feels that the most important point about EIA is to make sure a specific diagnosis is made. It is difficult at times to differentiate asthma from the normal breathlessness, which occurs with exercise. The feature of EIA that distinguishes it from normal breathing, or being "out of shape" is the fact that EIA is ALWAYS associated with a decrease in airflow. This can be measured with either a peak flow meter or a spirometer. It is also important that a specific diagnosis be made so that a person will not be labeled as asthmatic when they may be "normal" or have other conditions such as heart problems or anemia.
Dr. Cali also recommends before a person is labeled asthmatic, they have spirometric testing. An improvement in airflow after inhaling. A bronchodilator is an important indicator of asthma. Sometimes a bronchial challenge test is needed to diagnose asthma. In this test, the subject breathes in a known bronchoconstrictor in small quantities and the response is noted. Patients with asthma almost always respond to the inhaled agent by a reduction in airflow.
Inform Coaches – If coaches are made aware, than they can be prepared for the onset of EIA. Provide emergency contacts and medications with instructions, such as inhalers, should be available.
Warm and Moisten Air - Whatever the patient can do to warm and moisten the inhaled air can help prevent EIA. Nose breathing during exercise or wearing a loose covering over the mouth in cold weather may help. Sometimes, in severe cases, switching to an indoor sport like swimming may be necessary.
Start Out Slowly - It is important to start out slowly and warm up first before exercising at full tilt. Slowly jog around the track or field before practice or a game to prepare your lungs for full-speed.
Medications – are often necessary. Quick- acting bronchodilators like Albuterol, used 15-20 minutes before planned exercise, is recommended. This can be repeated once more during the exercise, but if tightness or wheezing occurs, the exercise should be stopped. Many patients with asthma require preventative treatment with anti-inflammatory medications. Inhaled steroids and/or leukotriene inhibitors may have to be added if the asthma is not controlled with Albuterol alone. In fact, some patients with asthma who are overly reliant on quick acting bronchodilator medications can get into serious trouble if they do not use inhaled steroids. Be sure to communicate your needs with your coaches.
Play Smart - In conclusion, people with asthma should not shy away from exercise. With proper precautions, people with asthma should be able to participate in all kinds of sports activities: baseball, football, soccer, swimming, tennis and running (even a marathon)! The key point is that the asthma needs to be under control and monitored by the patient, parents, coaches and doctor as a team.
Visit your doctor regularly and listen to your body.

Several years ago, while hiking to the bottom of the Grand Canyon with my family, my wife Esther developed “canyon knee,” also known as “hiker’s knee” or in medical terms, “patellar tendonitis.” Regardless of the term, the end result was that she had severe pain in the tendon below her knee cap and was unable to walk up the trail to get out of the canyon. In addition to ice, rest, bracing, and non-steroidal anti inflammatory medications, the National Park Ranger insisted that she use two trekking poles on her ascent to the rim.
Prior to that experience, I always thought that “walking, hiking sticks or trekking poles” were for show or those in need of a walking aide. Well, I could not have been more incorrect. Needless to say, Esther made it out of the canyon safely and, with the use of our life saving trekking poles; we have lived “happily ever after!” Now, 15 years later, I rarely walk more than 5 miles without my poles.
As a result of this experience, I have been recommending walking or trekking poles to my patients. These poles are an essential part of hiking or distance walking gear, for the novice and expert alike. Specifically, for those over 50 who have degenerative arthritis and pain in their lower back, hips, knees, ankles or feet, these simple devices have been shown to improve the efficiency of the exercise and lessen the impact on the spine and lower extremities. Additionally, using poles reduces the likelihood of ankle sprains and falls during walking. Trekking poles are also a safe option for those with compromised balance. If you want to walk distances for exercise and need a little stability but don’t want the stigma of a cane, trekking poles are for you.
Early explorers, Europeans and Native Americans have been using walking sticks for centuries. More recently, in the 1968 classic hiker’s bible, “The Complete Walker,” Colin Fletcher praised his “walking staff” for its multipurpose use: for balance and assistance with walking and climbing, protection from rattlesnakes, and for use as a fishing rod. Today, these sticks are now versatile poles made from light-weight materials.
Trekking poles are made of light-weight aluminum and vary in cost and quality. But, like most things, “you get what you pay for!” These hollow tubes can telescope to fit any person and collapse to pack in luggage for travel. Better poles offer multiple removable tips for various uses, conditions and terrains. For example, abasket to prevent sinking too deeply in snow, mud or sand; a blunt rubber tip for hard surfaces like asphalt or concrete, or the pointed metal tip to grip ice or hard dirt/gravel. Better quality poles offer an ergonomic hand grip and strap and a spring system to absorb shock through your hands, wrists and arms upon impact.
The poles should be properly adjusted to fit each individual. When your hand is griping the handle the elbow should be at a 90 degree angle. Proper use is simple; just walk with a normal gait pattern of opposite arm and leg swing. For example, left leg and right arm/pole swings forward to plant while the left arm/pole remain behind with the right leg .
This pattern is reciprocated with as normal gait advances (opposite arm and leg). I have been very pleased with my moderately priced poles (Cascade Mountain Tech from Dick’s Sporting Goods ($34.99 per pole). Prices range from $19.99 to 79.95 per pole. dickssportinggoods.com; montem.com; leki.com; rei.com. However, if you travel frequently to hike the State and National Parks, you may want to purchase more expensive poles that collapse and retighten more efficiently. (montem.com; leki.com;)
Montem Trekking Poles - with close-up of easy adjustable locking clasp.
There are numerous studies to support the use of trekking poles, especially research that supports their use for health and safety. One study compared hikers in 3 different conditions; no backpack, a pack with 15% body weight and a pack with 30% body weight. Biomechanical analysis was performed blindly on the three groups and a significant reduction in forces on lower extremity joints (hip, knee, and ankle) was noted for all three groups when using poles compared to those not using poles.
Another study confirmed that trekking poles reduced the incidence of ankle fractures through improved balance and stability. Additional studies support the theory that trekking poles reduce exercise induced muscle soreness from hiking or walking steep terrain and another study found that while less energy is expended in the lower body muscles using poles, increase energy is used in the upper body; therefore, the net caloric expenditure is equal as it is simply transferred from the legs to the arms.
In conclusion, it is important to remember that trekking poles for hiking or distance walking are much more than a style statement. They are proven to be an invaluable tool for health, safety and wellness by reducing lower extremity joint stress, improving stability and balance, and enhancing efficiency for muscle recovery.

Seasonal allergies affect 30 % of adults and 40% of children in the United States. Avoiding the outdoors is often not an option…especially if you enjoy outdoor activities and sports. Not long ago, it was unthinkable that an athlete with serious seasonal allergies could compete at a high level, such as the Olympics. Now, in great part due to advanced research, medications and proper management, an Olympic gold medal for those suffering from seasonal allergies is a reality. Recently, the National Institute of Allergy and Infectious Disease at the National Institutes of Health have published research on this topic to provide a better understanding and make recommendations.
The most common allergic reactions which athletes suffer from are sneezing, itchy and watery eyes, runny nose and coughing. Moreover, 67% of those with these symptoms also suffer from asthma. The athlete in NEPA is particularly vulnerable when the pollen count is high during spring and fall for several reasons. One, after being indoors all winter, one might develop a heightened sensitivity to allergens. Also, increased rapid and deep breathing during exercise makes athletes more susceptible to significant symptoms when exposed to allergens such as tree, grass and weed pollens.
Allergy skin testing can be performed to determine the allergens to which you are susceptible. Once determined, allergy shots are effective in building up tolerance to these allergens. If appropriate, you may be able to use allergy drops, administered under the tongue and conveniently used at home.
Asthma suffers should use their inhaler BEFORE symptoms occur. A recent study found that pretreatment using a short-acting bronchodilator inhaler within 15 minutes before exercise is very effective in preventing asthma symptoms for more than four hours. It is important to keep a bronchodilator available. If you fail to benefit from this, see your physician for other methods to control your exercise-induced symptoms.
Whether you have allergic respiratory problems from rhinitis or asthma, you many benefit from conditioning your airways with a 10 to 15 minute warm-up before and cool-down after the activity. This may serve to gradually prepare your lungs for an increased demand.
In addition to preventing dehydration on hot and humid days, constant hydration is very important for the athlete with allergies to prevent dry airways in athletes.
Know the signs and symptoms of asthma (coughing, wheezing, tightness in chest, shortness of breath).
Some schools have a file on each student athlete with a allergic or asthmatic problem which requires medication. The file includes information such as medical doctor release and instruction, emergency contacts and medications. Students must have their medications on hand before they can enter the field. The National Athletic Trainers Association recommends using a peak flow meter to monitor at risk players and can determine when a player can return to the field.
If possible, find an alternate practice facility with climate control for athletes at risk. Plan practices for these athletes when the pollen count is low. Check the newspaper or internet for pollen counts in your area. Training by the water, (ocean) where there is a breeze and less pollen is helpful.
Shower and change clothing immediately after being outdoors
During a flare up, do less aerobic exercise to limit stress on respiratory system. Try strength training indoors instead.
When pollen count is high, keep windows shut at home and in your car….use air-conditioning.
Keep pets out of your bedroom…especially when sleeping
Dry clothing in dryer…do not hang on clothesline outdoors

Fall in NEPA is one of my favorite times of year. For outdoor enthusiasts, there is nothing more refreshing than activities in the bright sunshine and crisp, clean air. The hot humid summer weather can be a deterrent to outdoor activities and this time of year provides an opportunity to get fit by beginning a walking program. For many who have not maintained an active lifestyle or have health issues, it is challenging to know where to begin. Moreover, beginning without a good plan can lead to injury and leave you discouraged. For example, those overweight and de-conditioned should not start a walking program too aggressively. Walking at a fast pace and long distance without gradually weaning into it will most likely lead to problems.
There is probably nothing more natural to human beings than walking. Ever since Australopithecus, an early hominin (human ancestor) who evolved in Southern and Eastern Africa between 4 and 2 million years ago, that our ancestors took their first steps as committed bipeds. With free hands, humans advanced in hunting, gathering, making tools etc. while modern man uses walking as, not only a form of locomotion, but also as a form of exercise and fitness. It is natural, easy and free...no equipment or fitness club membership required!
“There’s no question that increasing exercise, even moderately, reduces the risks of many diseases, including coronary heart disease, breast and colon cancer, and Type 2 diabetes,” said Dr. Jennifer Joyce, MD, professor of family medicine at GCSOM. “Research has even shown that you could gain two hours of life for each hour that you exercise regularly.” According to the American Heart Association, walking as little as 30 minutes a day can provide the following benefits:
Anything is better than nothing! However, for most healthy adults, the Department of Health and Human Services recommends at least 150 minutes of moderate aerobic activity or 75 minutes of vigorous aerobic activity, or an equivalent combination of moderate and vigorous aerobic activity. The guidelines suggest that you spread out this exercise during the course of a week. Also aim to do strength training exercises of all major muscle groups at least two times a week.
As a general goal, aim for at least 30 minutes of physical activity a day. If you can't set aside that much time, try several short sessions of activity throughout the day (3 ten or 2 fifteen minute sessions). Even small amounts of physical activity are helpful, and accumulated activity throughout the day adds up to provide health benefit.
Remember it's OK to start slowly — especially if you haven't been exercising regularly. You might start with five minutes a day the first week, and then increase your time by five minutes each week until you reach at least 30 minutes.
For even more health benefits, aim for at least 60 minutes of physical activity most days of the week. Once you are ready for a challenge, add hills, increase speed and distance.
Keeping a record of how many steps you take, the distance you walk and how long it takes can help you see where you started from and serve as a source of inspiration. Record these numbers in a walking journal or log them in a spreadsheet or a physical activity app. Another option is to use an electronic device such as a smart watch, pedometer or fitness tracker to calculate steps and distance.
Make walking part of your daily routine. Pick a time that works best for you. Some prefer early morning, others lunchtime or after work. Enter it in your smart phone with a reminder and get to it!
Studies show that compliance with an exercise program is significantly improved when an exercise buddy is part of the equation. It is hard to let someone down or break plans when you commit to someone. Keep in mind that your exercise buddy can also include your dog!
Like everything, there is a right way of doing something, even walking. For efficiency and safety, walking with proper stride is important. A fitness stride requires good posture and purposeful movements. Ideally, here's how you'll look when you're walking:

Can you believe that the 4th of July holiday was more than one month ago? Do not despair! There is still plenty of time to be outdoors in NEPA and experience so many activities such as: biking, hiking, running, walking, swimming, boating, golfing, and playing tennis to name a few. Late summer and early fall tend to be beautiful and is also a wonderful opportunity to discover your inner child, mix it up and try something new! Below are some new and exciting ways to stay active and have fun in the sun:
Spending time on any of the beautiful lakes in NEPA is time well spent. From an exercise standpoint, rowing, canoeing and kayaking offer a very special experience. Most kayaks are light weight, easy to use and maneuverable on a lake. Sitting low on the water offers a unique perspective as you feel yourself gliding across the lake. The Countryside Conservancy, in partnership with Lackawanna State Park, sponsors moonlight kayak events on the lake at the park. With a bright full moon, you can begin at 8 pm and return at 10 pm. Bring bug spray and headlights to enjoy the sunset and moon rise on the lake. You will feel like a kid breaking the rules of the park by being on the water after dark!
NOTE: Try kayaking in the daytime first and then advance to sunset trips before staying on the water for the moonlight. Rentals are available at the park.

Stand up paddle boarding (SUP) is becoming a fast-growing sport among water enthusiasts. It is a fun way to exercise your core, improve balance, and tone your upper body. It requires minimal equipment; a board that is essentially a long and wide surfboard and a long paddle to use while standing on the board. It can be done in the ocean surf, bay, lakes, or rivers; however, beginners would be wise to stay in calm water. Rentals are available at most beaches.
Check out the video for more information: REI paddleboard basics
What is it? Imagine a standup paddle board with a handlebar and pedals like a exercise stepper machine. Instead of using a paddle, you step up and down on the pedals and fins under the board propel you through the water. Check it out…Hobie Mirage Eclipse Stand Up Peddle Board; Dick’s Sporting Goods
Zumba is a very popular form of dance aerobics spiced up with Latin music. When adding water and sun to this already cool activity, you are assured to have fun while exercising. As with any aquatic exercise, the added resistance from the water gives arm rows and leg kicks more challenge. Female participants report an additional benefit; they are uninhibited to “shake that thing” to the music under the cover of the water. So, beat the heat, let loose and get some fun in the sun while you exercise.
NOTE: Consider trying regular Zumba first to get the hang of it. Amy Sekol is a local certified Zumba instructor and also offers Aqua Zumba. (amys.zumba.com)

I love this idea…why didn’t I think of it first! In the gym I enjoy the elliptical machine because it simulates running without the impact on my joints but of course, I would rather be outdoors. Well, this is the answer to my prayers…an elliptical machine that is attached to a bike with handle bars and brakes included. I think it will probably be difficult on steep hills but it is something I MUST TRY!

Summer heat and humidity are here and the risk of heat related illnesses are particularly high for those over 65, especially dehydration. Age, diet, illness and medications are some of the many reasons why elders suffer from dehydration not only in the summer heat, but year round. Furthermore, age related changes in 50-60 year olds can also make one vulnerable to dehydration if they are active and exercise in the heat. Not long ago, a local medical professional and good friend of mine was hospitalized for several days due to dehydration and associated illness. He is an active, fit, healthy 59 year old who continued his daily running for exercise during the June/July heat wave.
It is often forgotten that, next to oxygen, water is the nutrient most needed for life. A person can live without food for a month, but most can survive only three to four days without water. Even though proper hydration is essential for health, water gets overlooked as one of the six basic nutrients. Dehydration occurs when the amount of water taken into the body is less than the amount that is being lost. Dehydration can happen very rapidly (i.e. in less than eight hours); the consequences can be life threatening and the symptoms can be alarmingly swift.
In the body, water is needed to regulate body temperature, carry nutrients, remove toxins and waste materials, and provide the medium in which all cellular chemical reactions take place. Fluid balance is vital for body functions. A significant decrease in the total amount of body fluids leads to dehydration. Fluids can be lost through the urine, skin, or lungs. Along with fluids, essential electrolytes, such as sodium and potassium, are also perilously depleted in a dehydrated individual.
Dehydration is the most common fluid and electrolyte disorder of frail elders, both in long term care facilities and in the community! Elders aged 85 to 99 years are six times more likely to be hospitalized for dehydration than those aged 65 to 69 years. More than 18% of those hospitalized for dehydration will die within 30 days, and associated mortality increases with age. Men appear to dehydrate more often than women and dehydration is often masked by other conditions.
Elderly individuals are at heightened risk for dehydration for several reasons. Compared to younger individuals, their regulatory system (i.e. kidneys and hormones) does not work as well and their bodies have lower water contents. The elderly often have a depressed thirst drive due to a decrease in a particular hormone. They do not feel thirsty when they are dehydrated. This is especially true in hot, humid weather, when they have a fever, are taking medications, or have vomiting or diarrhea. They have decreased taste, smell, and appetite which contribute to the muted perception of thirst. Because of dementia, depression, visual deficits, or motor impairments, elderly persons may have difficulty getting fluids for themselves. Many elderly individuals limit their fluid intake in the belief that they will prevent incontinence and decrease the number of trips to the bathroom. The medications that they are taking (e.g. diuretics, laxatives, hypnotics) contribute to dehydration.
Elders may suffer headaches, fainting, disorientation, nausea, a seizure, a stroke, or a heart attack as a result of dehydration. The minimum daily requirement to avoid dehydration is between 1,500 (6.34 cups) and 2,000 ml of fluid intake per day. Six to eight good-sized glasses of water a day should provide this amount. Better hydration improves well-being and medications work more effectively when an individual is properly hydrated. Those who care for the elderly whether at home or in a health care facility need to be alert to the following symptoms (but these symptoms apply to both young and old):
Plain old tap water is a good way to replenish fluid loss. Some energy drinks not only have excess and unneeded calories but also contain sugar that slows down the rate at which water can be absorbed form the stomach. Consuming alcoholic and caffeinated beverages actually has an opposite, diuretic effect!
Visit your doctor regularly and listen to your body.
Keep moving, eat healthy foods, exercise regularly, and live long and well!
