While extreme heat can put everyone at risk of heat illness, health risks are greatest for vulnerable groups including:
- older adults, especially those living alone
- infants and young children
- people who work in the heat
- people experiencing homelessness
- people with chronic illnesses (like breathing problems, mental illness and heart problems)
- people on certain medications that increase risk in the heat or sensitivity to sunlight
Here are the best practices to follow to beat the heat:
- Stay hydrated and drink plenty of cool liquids, especially water; avoid caffeine and alcohol as they increase the risk of dehydration.
- Avoid heavy outdoor activity.
- Cool off in an air-conditioned space when available.
- Take cool baths or showers as often as needed or soak hands/feet/face in cool water.
- Wear loose, lightweight clothing; avoid dark colours that absorb more heat.
- Protect yourself by covering your body; wear a hat, sunglasses and sunscreen with UV protection.
