Your 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. Drinking fluids, replenishing salt and minerals and limiting time in the heat can help. Heat exhaustion is the milder form of heat-related illness that can develop after several days of exposure to high temperatures and inadequate or unbalanced replacement of fluids. Those most prone to heat exhaustion are elderly people, those with high blood pressure, and those working or exercising in a hot environment. The warning signs of heat exhaustion include the following:
heat exhaustion may progress to heat stroke. Seek medical attention if symptoms worsen or last longer than one hour. What steps can be taken to cool the body during heat exhaustion?
temperature: the body’s temperature rises rapidly, the sweating mechanism fails, and the body is unable to cool down. Body temperature may rise to 106°F or higher within 10 to 15 minutes. Heat stroke can cause death or permanent disability if emergency treatment is not provided. Warning signs of heat stroke vary but may include the following:
immediate medical assistance (dial 911) while you begin cooling the victim. Do the following: Get the victim to a shady area or air-conditioned environment. Cool the victim rapidly, using whatever methods you can. For example, immerse the victim in a tub of cool water; place the person in a cool shower; spray the victim with cool water from a garden hose; sponge the person with cool water; or if the humidity is low, wrap them in a cool, wet sheet and fan them 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. ***Remember ***keep cool and use common sense. Prevention is the key: Drink plenty of fluid throughout the day, avoid alcohol, replace salts and minerals (only if advised by your physician), wear appropriate clothing and sunscreen, pace yourself, stay cool indoors (with air conditioning is best), schedule outdoor activities carefully, seek shade, use a buddy system, monitor those at risk, and adjust to the environment. |
