As June moves along in southern Saskatchewan, the mercury slowly creeps up. And that can bring a few challenges.
"As we get into the summer months," Natalie Hazel, Warning Preparedness meteorologist with Environment Canada, "heat and humidity will become a more significant issue."
"The reason we include humidity because the way your body naturally cools off is through perspiration. When you sweat, you get that layer of basically water and as the water evaporates, it takes heat with it."
"But if the humidity is high, your body might produce some sweat but it's not going to evaporate. If the humidity is too high, the atmosphere can't take any more moisture so you just end up being a sweaty mess but you're not cooling off."
Exposure to high humidity and high heat can lead to heat exhaustion and heat stroke.
"Symptoms of heat illness include dizziness and fainting, nausea and vomiting, headaches, rapid breathing and rapid heartbeat and changes in behaviour in children."
Those who are most at risk are the elderly, children and those who spend a lot of time outdoors.
"You might have a job where you work outside and you're stuck working in the heat."
She advises trying to take regular breaks in a cool place and drink plenty of water.
Those who don't have access to shelter or an air-conditioned building are also at risk during heat waves.
"Being aware of the forecast really helps. Paying attention to how you feel and how those around you feel. Heat stroke is a medical emergency, call 911. Stay hydrated, stay cool."
