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.

Hot Temps and Exercise

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:

Signs of Heatstroke:

• Heat Exhaustion – can be a precursor to heat stroke
• Signs: cramps, weakness, fatigue, nausa
• Treatment: rest in shade, cool down with cool (not cold) towels, and drink plenty of fluids.
• Core Body Temperature above 105 degrees Fahrenheit
• Hot, dry skin – flushed but not sweaty
• Lack of sweating *
  • *NOTE: athletes often have external heatstroke and they can sweat even with an increase core temperature
• Very rapid pulse
• Mental confusion, disorientation or hallucinations
• Physical clumsiness, sluggishness or fatigue
• Seizure
• Dizziness

Treatment of Heatstroke:

• CALL 911 – Remember this may be life-threatening
• Relocate  – to a cool shady place or air-conditioned indoors and lie down with slight elevation of feet
• Undress – Remove outer garments and roll onto side to expose as much skin as possible to the air
• Cool Down – spray or sponge with cool water (not cold) and fan the skin
• Ice – place ice packs to the groin, neck and armpits to cool down large blood vessels. No ice bath.
• Core Temperature – is the only accurate measurement so medical personnel may take rectal temp if necessary. Must get core temp to 102 degrees Fahrenheit ASAP.
• Begin CPR – if breathing stops
• No Aspirin or Acetaminophen – to decrease temp
• Administer Fluids – if person is alert enough to swallow give 32 to 64 oz over 1-2 hours

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.

Benefits of being Outdoors:

• 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. It seems that the health concerns of ultraviolet light, sun burn, and skin cancer have created an overreaction to the point of Vitamin D deficiency in many. Balance and common sense go a long way. One can attain normal levels of Vitamin D by being outdoors in the sun and exposing their arms and legs for 10 -15 minutes a few times per week. Additional time in the sun warrants sunscreen and Vitamin D supplements can be used if necessary.

• 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. Some studies show that children in the United States spend an average of 6 ½ hours per day with electronic devices such as computers, video games and television. It is also reported that a child’s activity level more than doubles when they are outdoors. So, get out of the office, house, and gym as often as possible. Consider weight training at the gym and doing cardio by walking, biking, or running outdoors.    

• 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. Furthermore, studies show that exercising outdoors in the presence of nature, even for as little as 5- 10 minutes has additional mental health benefits. For those less active, read or listen to music in a hammock or lying in the grass.

• 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. Furthermore, it was discovered that these children scored higher on concentration tests following a walk in the park than they did after a walk in their residential neighborhoods or downtown areas, showing the benefit of the “green 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. Next time you’re recovering from an illness, discuss this with your physician.

• 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. Many pulmonologists believe people with pulmonary problems would benefit from outdoor activities such as a 10–15-minute walk because they are prone to osteoporosis and Vitamin D deficiency.  Local pulmonologist, Dr. Gregory Cali, DO, agrees, and also adds that studies do not show that high humidity is dangerous for respiratory patients, but it may be uncomfortable. In cold temperatures, those with pulmonary problems must avoid directly breathing cold air by covering up their mouths when walking outdoors. Overall, the benefits far outweigh the risks.

Most would agree that this spring has a little cloudy, rainy and cool in NEPA. However, warm sunny days are soon to come. While protection from the sun is very important, too much time indoors playing computer games and watching television, can lead to potential problems from lack of exposure to the sun. One must use good judgment and have balance as the potential exists for Vitamin D deficiency due to lack of sun exposure. This problem may be true for individuals who use too much protection or spend most of their day indoors due to occupation or poor health. Therefore, it will be the purpose of this column to discuss the importance of Vitamin D for health and wellness.

Vitamin D, a fat soluble vitamin, is found in food and can be made by your body after exposure to ultraviolet (UV) rays from the sun. The liver and kidney help convert it to its active form. Therefore, vitamin D assists calcium absorption, which is essential for normal development and in forming and maintaining strong bones and teeth. Without it, bones can become thin, brittle and soft. The classic Vitamin D deficiency diseases are rickets in children and osteomalacia in adults. Rickets results in skeletal deformities. Osteomalacia is the softening of bones. Therefore, it is essential for normal bone health and may diminish or prevent the onset of osteoporosis in the elderly.

The requirement for Vitamin D is dependent on age, sex, degree of sun exposure and the amount of pigmentation in the skin. Since it can be produced by the body and retained for long periods of time by the body’s tissues, the precise daily requirement has been difficult to determine. Instead, an Adequate Intake (AI) level has been established. AI is a level of intake sufficient to maintain healthy blood levels of an active form of Vitamin D.

AIs are similar for males and females but increase with age:

• Ages 19-50: 200 International Units (IU)
• Ages 51-69: 400 IU
• Age 70 and older: 600 IU

Sources of Vitamin D:

• Food Sources
  • Fortified foods are a major dietary source:
    • One cup of Vitamin D fortified milk: 98 IU
    • Dairy products (e.g. cheese, yogurt, ice cream) are generally not fortified
    • Orange juice, cereals, pastries, breads, crackers, cereal grain bars may be fortified; read the nutrition label for more information.
  • Only a few foods naturally contain significant amounts:
    • Salmon, cooked, 3 ½ oz: 360 IU
    • Mackerel, cooked, 3 ½ oz: 345 IU
    • Sardines, canned in oil, drained, 3 ½ oz: 270 IU
    • Liver, beef, cooked, 3 ½ oz: 30 IU
    • Egg yolk, one: 25 IU
• Exposure to sunlight:
  • Regular ultraviolet exposure stimulates the skin to produce Vitamin D.
  • Exposure to ultraviolet light or ambient sunlight
  • Exposing the face and hands for 20 minutes, 3 times a week can be sufficient
  • Exposing the hands, legs and arms for 5 to 10 minutes, 2 to 3 times a week, is more than adequate to satisfy requirements.

Vitamin D Deficiency:

Vitamin D deficiency can occur when dietary intake is inadequate, when there is limited sunlight exposure, when the kidney cannot convert Vitamin D to its active form or when Vitamin D is inadequately absorbed from the gastrointestinal tract. Season, geographic location, time of day, cloud cover, air pollution, sunscreens, living indoors and living in cities where tall buildings block adequate sunlight from reaching the ground affect UV ray exposure. Therefore, individuals with limited sun exposure are at risk of this deficiency. Homebound individuals, people living in northern latitudes (e.g. New England, Alaska), individuals who cover their bodies for religious reasons and people whose occupations prevent exposure to sunlight may need to supplement in other forms.

Sunscreens with a sun protection factor of 8 or greater will block UV rays that produce Vitamin D. Older adults have a higher risk for this deficiency because the skin’s ability to convert Vitamin D to its active form decreases with age and the kidneys, which help convert Vitamin D to its active form, do not work as well when people age. Individuals with pancreatic enzyme deficiency, Chron’s disease, cystic fibrosis, sprue, liver disease, surgical removal of part or all of the stomach or small bowel disease may need extra intake because Vitamin D is a fat soluble and they have reduced ability to absorb dietary fat. Supplements are often recommended for exclusively breast-fed infants because human milk may not contain adequate Vitamin D. Consult with your pediatrician on this issue.
