Common sense is the key to avoiding heat-related illness

(July 19, 2011) With the temperatures predicted to rise over the next few days, local public health officials offer tips for avoiding heat-related illness.

"Your best defense against heat-related illness is prevention," said Carol Paxton, Director of Emergency Preparedness for the Health Department of Northwest Michigan. "Staying cool and making simple changes in your fluid intake, activities, and clothing during hot weather can help you remain safe and healthy."

People suffer heat-related illness when the body's temperature control system is overloaded. The body normally cools itself by sweating. But under some conditions, sweating just isn't enough. In such cases, a person's body temperature rises rapidly. Very high body temperatures may damage the brain or other vital organs. Several factors affect the body's ability to cool itself during extremely hot weather. When the humidity is high, sweat will not evaporate as quickly, preventing the body from releasing heat quickly. Other conditions that can limit the ability to regulate temperature include old age, youth (age 0-4), obesity, fever, dehydration, heart disease, mental illness, poor circulation, sunburn, and prescription drug use and alcohol use.

To avoid heat-related illness, the U.S. Centers for Disease Control (CDC) & Prevention recommends: If you must be out in the heat, try to limit outdoor activities to the morning and evening hours and: Warning signs of heat stroke vary, but they may include an extremely high body temperature (above 103°F); red, hot, and dry skin without sweating; rapid, strong pulse; throbbing headache; nausea; confusion, and/or unconsciousness. If you see any of these signs, you may be dealing with a life-threatening emergency. Have someone call 911 while you begin cooling the victim. First, get him or her to a shady area. Cool the victim rapidly, using whatever methods you can. For example, place the person in a cool shower; sponge the person with cool water; or if the humidity is low, wrap the victim in a cool, wet sheet and fan him or her vigorously. Monitor body temperature and continue cooling efforts until the body temperature drops to 101-102°F. If emergency medical personnel are delayed, call the hospital emergency room for further instructions.

If exertion in the heat makes your heart pound and leaves you gasping for breath, STOP all activity. Get into a cool area or at least in the shade, and rest, especially if you become lightheaded, confused, weak, or faint.
