Extreme Heat

Protect Yourself during Heat Waves

Extreme heat can have health impacts, especially dehydration, significant fatigue, headache, nausea, and dizziness.

Avoid heat's harmful effects:

  1. STAY HYDRATED: Drink plenty of fluids (e.g., water, juice diluted with water, sports drinks without caffeine) without waiting to feel thirsty or as recommended by a doctor.
  2. KEEP COOL: Spend at least 2 hours a day somewhere cool (ideally with air-conditioning).
  3. LIMIT PHYSICAL ACTIVITY: Take it easy and reduce outdoor physical activities, particularly between 10 a.m. and 3 p.m.

Recommended Cool Places

There are many cool places available:

  • shopping centres
  • cinemas
  •  libraries
  • other air-conditioned places.

If you don't have air-conditioning at home, you should spend at least two hours a day in an air-conditioned place during a heat wave. If that is not possible, look for somewhere cool outside.

At-Risk Areas

Certain environmental features increase heat-related health risks. For example, urban areas with a significant amount of asphalted surfaces, certain types of buildings, and scant vegetation can create what is known as the "urban heat-island effect." Heat islands can be up to 12°C hotter than other areas in the same region. There is a high concentration of urban heat islands in the various municipalities in Estrie.

If you live in an urban heat island, you are at greater risk of having heat-related issues.
