Summer heat coming on strong; health official urge caution

With temperatures hovering in the mid to upper 90s for most of the week and expected to near triple digits by the end of next week, the Alabama Department of Public Health is encouraging the public to remain vigilant about the warning signs of heat illnesses.
Heat-related illnesses occur when the body’s temperature control system is overloaded.
Heat stroke, sometimes called sunstroke, is the most serious heat-related illness. It occurs when the body becomes unable to control its 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 degrees Fahrenheit or higher within 10 to 15 minutes. Heat stroke can cause death or permanent disability if emergency treatment is not provided.

“Heat stroke is a life-threatening emergency,” said Dr. Jim McVay, director of the Bureau of Health Promotion and Chronic Disease. “A person with heat stroke is likely to be unconscious or unresponsive, so he or she cannot safely consume any liquids. Under no circumstance should you give any alcohol to a person with heat stroke or any heat-related illness.”
People should drink plenty of water, stay in an air-conditioned room, and keep out of the sun. It is also important to check on the elderly and ensure pets have plenty of water to drink and shade to cool off.
Warning signs of heat stroke vary, but include the following:
- An extremely high body temperature (above 103 degrees Fahrenheit)
- Red, hot and dry skin (no sweating)
- Rapid, strong pulse
- Throbbing headache
First aid recommendations are to get the person to a shady area, cool rapidly in a tub of cool water, place in a cool shower, spray with cool water from a garden hose, splash with cool water, or, if the humidity is low, place in a cool, wet sheet and fan vigorously. Monitor body temperature and continue cooling efforts until the person’s body temperature drops to 101 to 102 degrees Fahrenheit.
Heat illness can likely be avoided by following these preventive measures:
- Drink more fluids, and avoid beverages containing alcohol or caffeine.
- When temperatures are extreme, stay indoors, ideally in an air-conditioned place.
- Take a cool shower or bath, and reduce or eliminate strenuous activities during the hottest times of the day.
- Protect yourself from the sun with a wide-brimmed hat, light-colored, loose-fitting clothing and use of a sunscreen of SPF 15 or higher.
- Never leave pets or people in a parked vehicle.
Those at special risk of becoming ill in this weather are young children, the elderly and individuals with heart problems, poor circulation, diabetes, a previous stroke or obesity. The risk of heat-related illness may increase among people using medications for high blood pressure, nervousness or depression.
