Ontario: You'll NEVER guess the best ways to beat the August long weekend heat

Wednesday, July 31st 2019, 9:23 am - The August long weekend is getting closer and we want to give you all the useful weather-related tips to plan for it, including how to beat the heat.

This week, we are taking you Beyond The Forecast, giving you all the weather-related tips you'll need to make the most of this upcoming, and second to last, long weekend of the summer. So far, we've checked in on the overall glorious weather pattern taking shape, along with a nice bump in lake temperatures that will make for an ideal "floatie forecast."

Now as we move even closer to the weekend kickoff, parts of Ontario are really looking to solidify that spot for some "winning" weather conditions. That's as temperatures soar to the lower 30s and the shower and thunderstorm chances remain fairly isolated.

Whether you'll be hanging out dockside within cottage country, or sticking closer to home for a much needed staycation, the abundant sunshine and warming temperatures will leave you finding ways to try and stay comfortable and cool.

Weather Network meteorologist Nicole Karkic put the heat to the test with these effective, yet surprising, tips to truly beat the heat during this much anticipated summer holiday weekend (and beyond):

Civic LongWeekend


1) Pass the cayenne pepper and jalapeños! It may sound counter-intuitive, but spicy foods are great in the heat because it can increase sweating without raising body temperature. As moisture evaporates from the skin, the body cools down.

2) Take your vitamins. Some studies have shown that increasing Vitamin C can regulate body temperature and support the immune system's response to heat-related illnesses such as heat rash or heat exhaustion.

3) Seek shade. That may seem obvious, but here's a lesser-known fact: Shade from a tree will feel cooler than the shade cast by a building, thanks to a phenomenon called "transpiration." Transpiration occurs when water vapour is released through a plant's leaves, creating a cooling effect on the surrounding air.

4) Here’s some food for thought: Cool treats, like ice cream and icy beverages, won't necessarily cool you down. Ice cream provides a cooling effect because of its high-fat content, which requires more work for the body to digest, triggering a rise in internal body temperature. As for drinks, hot can be a better choice than cold, because warm drinks will maintain hydration and promote the cooling effect of sweating.

But icy treats make me feel cooler. What gives?

"The cooling effects of cold liquids are more likely explained by their rehydration effects," writes Peter Poortvliet, a post-doctoral research Fellow in neuroscience at the University of Queensland.

"Sweating is the most effective way our bodies lose heat. Sweating occurs when an increase in core body temperature is detected by the brain, which responds by stimulating the sweat glands distributed all over the body to produce sweat."

5) Choose your clothing wisely. Dark materials heat up faster than white ones in the sun because the dark colours allow clothing to absorb more heat energy.

Wired recently tested this theory out using shirts in a variety of colours that were left in the sun using data recorded by an infrared camera.

In a series of tests, the white shirts appeared to be the "cooler" choice, because they don't absorb as much visible light.
