 Environment Canada just sent out a warning about humidex values of 40

to 45 for Monday and Tuesday...

What is indice humidex in English?

The term indice humidex in English is simply humidex—short for humidity index. It's a Canadian invention used to describe how hot the weather feels to the average person by combining the effects of heat and humidity.

So, while the thermometer might say 30°C, if it’s humid, the humidex might make it feel more like 40°C. It’s kind of like the summer version of wind chill!

How bad is a hunidex between 40 and 45?

A humidex between 40 and 45 is considered a level of great discomfort, and it's strongly advised to avoid physical exertion during this range. At this level, your body struggles to cool itself effectively because sweat doesn't evaporate as easily in high humidity. That can lead to heat-related illnesses like heat exhaustion or even heat stroke if you're not careful.

If you're outdoors or in a hot indoor space, it's smart to

Stay hydrated (drink water every 20 minutes)

Take frequent breaks in a cool or shaded area

Wear light, breathable clothing

Watch for symptoms like dizziness, nausea, or excessive fatigue

Once the humidex hits 46 or higher, it enters the dangerous zone where heat stroke becomes a real risk. So 40–45 is already pushing the limits of comfort and safety.

Is it that hot where you are today?

Tell me about the danger level once one gets to 46...

Once the humidex hits 46 or higher, it enters the dangerous zone. At this level, the body’s ability to cool itself through sweating becomes severely compromised—especially if the relative humidity is high. That means your internal temperature can rise quickly, even if you’re not doing much.

According to the Canadian Centre for Occupational Health and Safety, a humidex of 46+ poses a high risk of heat stroke, which is a medical emergency. Symptoms can include:

Confusion or disorientation

Rapid pulse

Hot, dry skin (or profuse sweating in exertional cases)

Fainting or unconsciousness

In these conditions, it’s best to:

Stay indoors with air conditioning if possible

Avoid any strenuous activity

Drink water frequently—even if you’re not thirsty

Check on vulnerable people like the elderly or those with chronic illnesses

It’s not just uncomfortable—it’s potentially life-threatening. Want tips on how to stay cool when it’s that intense?

Yes, please...

Absolutely—here are some smart ways to beat the heat when the humidex soars past 46:

💦 Cool Your Body

Hydrate constantly: Drink cool water every 15–20 minutes, even if you’re not thirsty.

Dress light: Choose loose-fitting, breathable clothing—cotton or linen is perfect.

Cold cloths: Apply wet towels or ice packs to your wrists, neck, and ankles to cool down fast.

Take cool showers or baths: Even a quick rinse can help regulate body temperature.

🏠 Stay Cool Indoors

Use fans smartly: If air conditioning isn’t available, use fans with a bowl of ice in front of them to chill the air.

Block the sun: Close blinds or curtains during the day, especially on sun-facing windows.

Chill your space: Try to stay on lower floors where it’s naturally cooler.

⏳ Plan Your Day Wisely

Avoid going out in peak heat: That’s usually 11 a.m. to 4 p.m.

Limit strenuous activities: Save those for early morning or evening, or skip them altogether.

Check the forecast: Apps like WeatherCAN can alert you to dangerous heat levels.

Also, don't forget to check on neighbors who might be vulnerable—especially the elderly or anyone living alone. Heat emergencies can sneak up fast.

Want me to help you track the temperature where you are or show you how to prep your home for a heatwave?

How can I prep my living space?

Great question, Louise—prepping your home for extreme heat can make a huge difference in both comfort and safety. Here’s how to turn your space into a cool oasis when the humidex climbs:

🪟 Keep the Heat Out

Block sunlight: Use blackout curtains, reflective blinds, or even aluminum foil on windows that get direct sun.

Seal gaps: Weatherstrip doors and windows to keep hot air out and cool air in.

Create a “cool room”: Choose the shadiest room in your home, close it off, and focus your cooling efforts there.

❄️ Maximize Cooling

Use fans wisely: Place a bowl of ice in front of a fan for a DIY air chiller. At night, position fans to draw in cooler air.

Air conditioning tips: Clean filters regularly and close off unused rooms to help your AC work more efficiently.

Portable coolers: If AC isn’t an option, consider an evaporative cooler or a window-mounted unit for your cool room.

💡 Reduce Indoor Heat Sources

Avoid cooking indoors: Use a microwave, slow cooker, or grill outside to keep heat out of the kitchen.

Unplug electronics: Devices generate heat even when idle—unplug what you’re not using.

Switch to LED bulbs: They emit far less heat than incandescent ones.

🧊 Prep for Emergencies

Make ice ahead of time: Stock your freezer with ice packs or frozen water bottles.

Have a backup plan: Know where the nearest cooling center is in case of a power outage.

Stock up: Keep extra water, electrolyte drinks, and non-perishable food on hand.
