HALIFAX - With the humidex bringing temperatures into the low to mid-thirties for the Canada Day long weekend, heat stroke can happen quickly.
The symptoms of heat exhaustion can include lightheadedness, dizziness, excessive sweating, nausea and even vomiting.
If you experience these symptoms, you should get out of the sun, find a cooler place and drink plenty of water as staying in the sun can lead to heat stroke.
Dr. Robert Strang, the province's chief medical officer of health, told the Sheldon MacLeod Show these symptoms pose an immediate danger to health.
"If someone actually has gone to the point of not sweating, losing consciousness or is very confused, that's a medical emergency and they need to call 911," he said.
He said children and the elderly are the most likely to be negatively effected by the heat, so its important to check on your loved ones during the hottest times of the year.
Dr. Strang also says excessive use of alcohol can increase you risk of dehydration, adding it's important to drink as much water as you can if you plan of spending time in the heat.
