Heat Advisory



Hot and humid conditions continue in Manitoba.  Higher temperatures and humidity levels are forecast for Sunday.

Communities in the southern part of the province, including the city of Winnipeg and surrounding areas, are expected to reach high humidex values.

The chief provincial public health officer is reminding Manitobans to take precautions to prevent heat‑related illness.

The effects of heat can be reduced by:

  •     drinking plenty of liquids, preferably water, before feeling thirsty;
  •     limiting physical activities;
  •     wearing a wide-brimmed hat or using an umbrella;
  •     wearing loose-fitting, light-coloured clothing;
  •     going to a cool place such as a mall, restaurant or movie theatre for a break from the heat if there is no air conditioning at home;
  •     taking a cool bath or shower; and
  •     limiting alcohol consumption.

Remember to check on family members, neighbours and friends when it gets hot, especially older adults and people with chronic conditions.  Do not leave people or pets alone in closed, parked vehicles, even for a few minutes and avoid leaving them in direct sunlight.

It’s important to wear sunscreen to prevent sunburn when you are outdoors.  Having a  sunburn can make it more difficult for your body to cope with heat.

Prolonged exposure to heat can lead to a variety of symptoms including headache, nausea, weakness, dizziness, fainting, confusion, rapid breathing and dehydration.  If any of these symptoms are associated with heat or sun exposure, move to a cool or shaded place immediately, drink sips of water or other liquids, lie down and sponge with cool water.  Emergency medical attention may be required depending on the severity of symptoms. 

Exposure to heat for too long a period can lead to dehydration, heat exhaustion, heat stroke, worsening of other conditions or, rarely, death.  Health risks related to heat are higher for older adults, young children, people on certain medications and people with chronic conditions.  However, everyone is potentially at risk.

The effects of heat can build up over a few days if the temperature and humidity do not drop.  Plan activities carefully and look for opportunities to get a break from the heat.  The elderly, individuals living alone, people with chronic conditions and people on certain medications should take extra care.

Remember the five key points on preventing heat-related illness:

  •     plan activities carefully,
  •     hydrate with water,
  •     seek cool places,
  •     check on others, and
  •     know the signs and symptoms of heat-related illness.
