“Heat-related illnesses are a high risk for older adults, children, and those with chronic illnesses,” said Dr. Karalyn Dueck, Medical Officer of Health. “Any individual can be impacted, though, especially if they work or are active outdoors, and it is recommended they take steps to combat the heat and stay cool.”
Symptoms of heat exhaustion may include rapid breathing, dizziness or fainting, vomiting, rapid heartbeat, extreme thirst, and decreased urination that is unusually dark yellow in colour. If you are experiencing these symptoms, please move to a shaded or air-conditioned area, drink plenty of water, and rest. If symptoms persist, please seek urgent medical attention.
