What is a common preventive measure against heat illness?

Staying indoors in air conditioning is a common preventive measure against heat illness because it helps maintain a cooler body temperature in extreme heat conditions. Air conditioning reduces exposure to high temperatures, lowering the risk of heat-related illnesses like heat exhaustion or heat stroke. It creates a controlled environment where humidity and temperature are regulated, leading to better hydration and comfort levels.

In contrast, consuming alcohol frequently can lead to dehydration, which increases the risk of heat illness rather than preventing it. Wearing heavy clothing can trap heat and sweat close to the body, which can exacerbate overheating and make heat-related illnesses more likely. Therefore, opting for air conditioning is a practical and effective strategy for preventing heat illness.
