Extreme heat already causes measurable health impacts in our region and will become more of an issue as the climate warms. These events can trigger a number of heat-related illnesses (such as heat exhaustion, heat stroke) and in extreme situations, can lead to permanent disability or death. Older adults, people with chronic conditions, people on certain medications, infants and young children are especially sensitive to the health effects of heat.
Symptoms of heat illness can range from mild to severe.
dizziness or fainting
nausea or vomiting
rapid breathing or heartbeat
or changes in behaviour such as confusion, lack of coordination or hallucinations.
Severe cases can lead to heat stroke, a condition requiring immediate medical care.
Making sure that people have a way to stay cool and drink plenty of water is the best way to prevent heat-related illnesses during extreme heat events. Call 911 if you think a person requires immediate medical care. The resources below provide information on the symptoms of heat-related illness and how to stay healthy in the heat.
