Signs of Heat Exhaustion and Stroke

Watch for the early signs of heat exhaustion in yourself and others. Signs include headache, nausea, dizziness, thirst, dark urine, and intense fatigue. Stop your activity and drink water immediately if you experience these symptoms.

Heat stroke is a medical emergency. Call 911 or your emergency health provider if you or someone around you shows signs of heat stroke. These signs include red and hot skin, dizziness, nausea, confusion, and a change in consciousness. While you wait for medical attention, cool the person by moving them to a cool place, removing extra clothing, and applying cold water or ice packs around their body.

How to Stay Cool

Drink water often and before you feel thirsty to replace fluids. Close your blinds or shades and open windows if the outside air is cooler than the inside air.

Turn on your air conditioning, use a fan, or move to a cooler area of your home. If your living space gets too hot, move to a cool public space like a cooling centre, community centre, library, or shaded park. Follow the advice of your regional public health authority.

Plan and schedule outdoor activities during the coolest parts of the day. Limit your direct exposure to the sun and heat. Wear lightweight, light coloured, loose fitting clothing and a wide brimmed hat.

Never leave people or pets inside a parked vehicle. Check your vehicle before locking it to make sure no one is left behind.
