Hot weather triggers a variety of medical emergencies. Even healthy people should take it easy during extremely high temperatures, and those with respiratory and other health problems must be especially careful. Stay out of the sun as much as possible. Drink extra fluids, but avoid alcoholic beverages.
Alcohol can cause dehydration.
Drink before you're thirsty and drink often. Eat a healthy diet. Wear a hat or cap, keep the neck covered and wear loose fitting clothing. If you can, work in the cool hours of the day or evening. The greatest amount of heat loss from the body occurs at the head.
