Heat Rash

How can people protect their health when temperatures are extremely high?

The body can adapt very well in hot weather, but it takes time to acclimate. The actual temperature is just one factor when a person decides to work, play, or exercise in the heat. The heat index adds humidity to the equation since sweat cannot evaporate if the water content in the air (humidity) is high. If the air holds as much water as it can there is no place for sweat to go, and evaporation cannot cool the body.

To minimize the risk of  heat-related illnesses, try to avoid working or exercising in extreme heat. Avoid dehydration and other complications by taking frequent breaks to get out of the heat, and drinking plenty of water or other fluids to replenish fluid lost through sweat.

Early signs of heat-related illnesses include lightheadedness,weakness, and nausea. It is important to get out of the heat, cool off, and rehydrate immediately to avoid severe heat-related problems such as heat exhaustion and heat stroke.
