The name of the game today has been keeping cool. 

It was sweltering all day July 15, 2013, but this is not record breaking heat.  However, with the humidity it feels much hotter than the thermometer reads. For people who have to work in this sweltering weather, it felt even hotter and today.

Temperatures reached the high 30s today.

“It's ridiculously hot out here,” says  Dave Kuhen. “You gotta wear sunscreen and drink water or you will suffer.”

Depending on where you are and what you are doing, it can feel hotter or in some cases cooler. For example at the beach today it was 37C but take a few steps over to the shade its much cooler at 26C.

And with it that cool in the shade, it’s where you’d find Catheryn Sikina and her young granddaughter.

“I don't want to get burnt and though we have sunscreen on it will be enough sun being on the beach,” she say.

Sunscreen and water is the only relief for people who have work outdoors. Landscaper Nina Leuty is actually working in near 40C temperatures.

“It's a little tough but I take lots of breaks and drink plenty of water,” she says.

And it's even hotter for construction worker Travis Whitmore. The temperature on his excavator was climbing close to 50C.

“It feels that hot with this running,” he says.  “It’s definitely hotter than it is out there. But you gotta work pay the bills.”

The heat is keeping Dr. Robert Gabor extremely busy in the ER department at Royal Victoria Regional Health Centre. Before the temperatures even peaked, he had already seen four people for heat exhaustion.

“The body’s natural defense mechanism of sweating is not going to kick in properly because it's so hot and humid,” he says. “You are not going to get that heat loss to cool down your body. Heat exhaustion can come on quickly.”

And in this heat, cars can quickly turn into an oven and there doesn't seem to be much of difference whether your car is parked in the shade or is in the sun with the windows down.

Young children, seniors, and anyone with a compromised immune system are at the greatest risk of getting sick. If you are out in this heat, doctors highly recommend drinking plenty of water, staying inside in air-conditioned building or at the very least sitting in a shaded area.
