Province Reminds Manitobans to Make Heat Health Part of Summer Planning

As summer approaches, Manitoba Health is reminding Manitobans to make heat health part of summer planning by knowing health-related risks of heat, taking precautions to prevent overheating, learning how to recognize and respond to symptoms of heat illness, and following the province’s Twitter channel @MBGov for timely updates and warnings.

When temperatures and humidity levels are high—especially for prolonged periods—everyone is at risk for heat illness. However, risks are higher for older adults, infants and young children, people with chronic conditions and people living alone, especially those living in urban areas or without air conditioning. People who work or exercise in the heat are also at higher risk.

High temperatures and humidity levels early in the summer may have a greater health impact because people have not yet adapted to the weather. Additionally, people living in the north may be at higher risk, if accustomed to cooler temperatures.

Heat warnings are issued when temperature and humidex levels are expected to meet established criteria. Throughout the summer months, these warnings will be shared from the Twitter channel @MBGov. Updated weather forecasts are available from Environment and Climate Change Canada at

Manitobans are encouraged to check in regularly with vulnerable or isolated community members, friends and family who might be at risk.

All Manitobans can take care to prevent heat illness by:

  • drinking plenty of liquids, especially water, before feeling thirsty;
  • avoiding prolonged sun exposure;
  • cancelling outdoor activities or rescheduling them to cooler times of the day;
  • if working outdoors, taking more breaks and staying well hydrated;
  • wearing loose-fitting, light-coloured clothing and a wide-brimmed hat;
  • limiting alcohol consumption;
  • blocking sun out at home during the day by closing awnings, curtains or blinds;
  • taking a cool shower or bath; or
  • going to a cool place such as a mall, community centre, public library or place of worship.

Heat illness can cause a variety of symptoms including:

  • headache;
  • nausea;
  • dizziness;
  • weakness or tiredness;
  • muscle cramps; or
  • rapid breathing or pulse.

Anyone experiencing these symptoms should move to a cool or shaded place, lie down, drink water and use cold compresses.

If someone loses consciousness, is confused, or has red, hot and dry skin, call 911. This may be heat stroke, which is a medical emergency. While waiting for emergency medical help, move the person to a cool or shaded place, apply cold water to large areas of their skin or clothing, and fan the person as much as possible.
