The human body maintains a fairly constant internal temperature, even though it is being exposed to varying environmental temperatures. To keep internal body temperatures within safe limits, the body must get rid of its excess heat, primarily through varying the rate and amount of blood circulation through the skin and the release of fluid onto the skin by the sweat glands. Hot weather makes our bodies work harder - just to get rid of the heat.

During hot weather we need to take care of ourselves. When the body is unable to cool itself by sweating, heat stress, heat exhaustion or the more severe heat stroke can occur, and can result in death.

Make frequent checks on elderly, ill or disabled relatives, friends or neighbors and help them keep cool.

Tips for Preventing Heat-Related Illness

• Block out direct sun or other heat sources.
• Drink lots of water: about 1 cup every 15 minutes. Do not wait until you feel thirsty.
• Wear lightweight, light-colored, loose-fitting clothes.
• Avoid alcohol, caffeinated, or very cold drinks and heavy meals.
• Infants should drink breast milk or formula.
• Stay indoors and, if at all possible, stay in an air-conditioned place.
• Fans may provide comfort, but when the temperature is in the high 90s, fans will not prevent heat-related illness. Taking a cool shower or bath, or moving to an air-conditioned place is a much better way to cool off.
• NEVER leave anyone in a closed, parked vehicle.
