High temperature + high humidity + physical work = heat illness.

Protect yourself.

• Learn the signs and symptoms for heat-induced illnesses and how to respond.
• Drink plenty of cool water.
• Avoid eating large meals before working in hot environments.
• Avoid beverages with caffeine. These make the body lose water and increase the risk for heat illnesses.

Factors that put you at increased risk.

• Taking certain medications. Check with your health-care provider or pharmacist to see if any medicines you are taking affect you when working in hot environments.
• Having a previous heat-induced illness.
