Learn about heat-related illnesses

Very high temperatures can be dangerous and cause heat discomfort such as heat exhaustion, fainting, heat rash and muscle cramps. Heat discomfort can affect you quickly and is mostly caused by overexposure to heat or excessive physical exertion. Watch your local forecast and weather alerts to prepare for the harshest weather conditions.

Know the risks

You are at greater risk of developing heat-related discomfort if you have certain conditions, such as respiratory disease, heart problems, mental illness such as depression or dementia, or if you take certain medications. If you are taking medication or have a health problem, ask your doctor or pharmacist if heat is a health risk and follow their recommendations.

Stay hydrated

Drink plenty of cool liquids, especially water, before you feel thirsty to reduce the risk of dehydration. Leave a glass by the sink to remind yourself to drink water and eat more fruits and vegetables that have lots of water.
