Heat Related Illnesses (cont.)
Infants and children up to four years of age are sensitive to the effects of high temperatures and rely on others to regulate their environments and provide adequate liquids. People 65 years of age or older may not compensate for heat stress efficiently, and are less likely to sense and respond to changes in temperature. Overweight people may be prone to heat sickness due to their body's tendency to retain more body heat. Any health condition that causes dehydration makes the body more susceptible to heat sickness. If you or someone you know is at higher risk, it is important to drink plenty of fluids; avoid over exertion; and get your doctor or pharmacist's advice about medications taken for high blood pressure, depression, nervousness, mental illness, insomnia, or poor circulation.
Hot weather health emergenciesEven short periods of high temperatures can cause serious health problems. Two common problems are heat stroke and heat exhaustion.
Heat StrokeHeat stroke 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°F or higher within 10-15 minutes. Heat stroke can cause death or permanent disability if emergency treatment is not given.
