Canadians don’t deal well with sustained heat and humidity. Sure, the odd day or two of over 30 gives us something to complain about, because we love to complain about the weather. But day after day of +30C with high humidex? That’s something we don’t adapt to very well.
Many people around the planet, however, do effectively live in and deal with these high temperatures all the time. Here’s what we can borrow from their experience.
Slow down. It’s often cold in Canada, so rushing from one thing to another in our day is not only possible, but it also helps keep us warm by generating body heat. That’s the last thing you want to do in high heat and humidity environments. Moving slowly decreases the heat you are generating and keeps your core temperatures down.
Avoid activity in the heat of the day. In the tropics, the most productive times of the day or in the early morning and late after. Minimize activity and movement when possible. The middle of the day is for finding shade and rest.
Stay hydrated. This isn’t just about water. Many cultures who live in hot climates have traditional beverages that help manage hydration. Coconut water, cold teas, like yerba mate in South America, lime juice, and water. Drinks like these are refreshing and contain electrolytes as well as water.
What happens when you don’t manage heat well? You run the risk of heatstroke, also known as sunstroke–a type of severe heat illness that results in a body temperature greater than 40.0 °C (104.0 °F).
Symptoms of heatstroke include:
- Throbbing headache
- Dizziness and light-headedness
- Lack of sweating despite the heat
- Red, hot, and dry skin
- Muscle weakness or cramps
- Nausea and vomiting
- Rapid heartbeat, which may be either strong or weak
- Rapid, shallow breathing
What to do about it:
- Get to a shady or air-conditioned place
- Cool off with damp sheets and a fan
- Take a cool shower or bath
- Rehydrate (with NON-sugary beverages)
If you don’t feel better in 30 minutes, it’s off to the doctor with you! You may need IV fluids.
