The risk of heat related injuries such as heat exhaustion and heat stroke may be elevated due to the cool and rainy spring Manitobans may be acclimatized to.

With an extended period of hot weather, Environment Canada has continued the Heat Warning.

Extreme heat affects everyone.

To reduce the health effects of heat:

- Plan outdoor activities during cooler times of the day and take into account the COVID-19 restrictions.
- Take a cool shower or bath or take a break in a cool location, such as an air-conditioned building or a tree-shaded area.
- Stay out of direct sunlight and wear loose-fitting, light-coloured clothing and a wide-brimmed hat or shade yourself with an umbrella.
- Drink plenty of water, before you feel thirsty and stay in a cool place. If you must go out, take water with you.
- Keep your house cool. Block the sun out by closing curtains, blinds, and awnings during the day
- Never leave people or pets in a parked vehicle.
- Check on family, friends and neighbours. Check regularly on people living alone, especially older individuals or people with health conditions. Make sure they are cool and drinking water.
- Watch for the effects of heat illness: swelling, rash, cramps, fainting, and the worsening of some health conditions.
- Watch for signs of heat stroke (which may begin with headache, hot skin, dizziness or confusion) and take action immediately.
