Heat illnesses include heat stroke, heat exhaustion, fainting, edema (swelling of hands, feet and ankles), heat rash and muscle cramps.
Health risks of extreme heat During periods of extreme heat, the risks of heat illness are greatest for:
• older adults
• infants and young children
• people with chronic illnesses, such as breathing difficulties, mental illness or heart conditions
• people who work in the heat
• people who exercise in the heat
• homeless people
• low-income earners.
Also, if you are taking medication or have a health condition, ask your doctor or pharmacist if it increases your health risk in the heat and follow their recommendations.
When it’s very hot: • spend some time in a cool place;
• drink a lot of water - don’t wait until you’re thirsty;
• reduce physical effort.
