A heat alert has been issued by the Sudbury and District health unit for the Sudbury and Manitoulin regions.
Alerts are called when the combination of temperature and humidity exceeds 36C.
It's expected feel closer to 40C today and Tuesday, which prompted the health unit's alert.
Exposure to extreme heat can lead to heat exhaustion and heat stroke, they said. People are advised to wear light-coloured and loose-fitting clothing, avoid going out in sun or heat when possible and to drink plenty of water.
Drinks containing caffeine and alcohol should be avoided, they said.
The Health Unit provided the following tips on how to prevent heat-related illness:
- Keep electric lights off or turned down low.
- Take a cool bath or shower periodically, or cool down with cool, wet towels.
- Take lots of rest breaks, preferably in the shade or in an air-conditioned area such as a library, community centre, shopping mall or a cooler area of your building.
- Avoid heavy meals and using your oven.
- Place a dish of ice cubes in front of your electric fan. It has a cooling effect.
- Check in at least once a day on family, friends, and neighbours who may have difficulty dealing with the heat.
