Keep Your Cool in Hot Weather!

Learn about heat-related illness and how to stay cool and safe in hot weather.

High temperatures kill hundreds of people every year. Heat-related deaths and illness are preventable, yet more than 600 people die from extreme heat every year.

Take measures to stay cool, remain hydrated, and keep informed. Getting too hot can make you sick. You can become ill from the heat if your body can’t compensate for it and properly cool you off. The main things affecting your body’s ability to cool itself during extremely hot weather are:

High humidity. When the humidity is high, sweat won’t evaporate as quickly. This keeps your body from releasing heat as fast as it may need to.
Personal factors. Age, obesity, fever, dehydration, heart disease, mental illness, poor circulation, sunburn, and prescription drug and alcohol use all can play a role in whether a person can cool off enough in very hot weather.
