On a hot summer day a quick step outside is enough to know the temperatures can climb quickly. And while many may bask in the sun's warm rays, some serious dangers are attached to high temperatures.

Heat Waves

So what's the difference between a streak of warm days and a heat wave?

"Everybody uses the phrase "heat wave" colloquially, but in Canada, it's actually a specific term. Typically, temperatures need to be at or above 32C for three consecutive days to qualify -- although try telling someone who's sweltering that it's not "technically" a heat wave!" said Daniel Martins, a writer for The Weather Network.

So are heat warnings always in effect during a heat wave? Not so fast Martins said.

 

 

"Unlike heat waves, which are based on how many days temperatures are above a certain level, heat warnings are declared usually ahead of time when temperatures are expected to reach dangerous levels. In Ontario, Environment Canada issues heat warnings when daytime highs are expected to reach 30C AND the humidex makes it feel like 40 ... OR when temperatures are expected to reach 40C or greater," he explained. "So depending on the circumstances, you could have a three-day heat wave and only see heat warnings issued for one or two of those days. Heat warnings are really meant to warn the public of the health hazards of the heat, not help decide whether it's a "proper" heat wave."

How does the heat affect us?

According to the Canadian Centre for Occupational Health and Safety's website, rising temperatures and humidity can lead to people displaying a variety of symptoms.

If exposure to heat continues any of the following illnesses are possible.
