Symptoms of heat-related illness include rapid breathing, dizziness or fainting, vomiting, rapid heartbeat, extreme thirst, decreased urination and unusually dark yellow urine.
During heat events, remember to check-in with family, friends and neighbours, especially seniors who live on their own. It's best to call or video-conference – if that is not possible, practice physical distancing.
Due to COVID-19, some locations that normally provide relief from the heat, such as shopping malls and cooling centres, have reopened. Please check with your local municipality for operating hours.
If you experience any of the mentioned symptoms, cool off as soon as possible by taking a cool bath or shower, move to a shaded area, drink some water and rest. If the symptoms persist, contact your doctor or call 911.
Peel Health recommends the following steps to be taken to prevent heat related illness:
Establish a policy and plan to deal with extreme temperatures.
Keep children cool and if at all possible, stay in an air-conditioned place.
Limit time outdoors between 11 a.m. – 4 p.m. when temperatures and UV radiation are most intense. Offer regularly scheduled rest periods.
When outdoors, stay in the shade whenever possible (natural or artificial structures).
When in the sun cover up. Ensure children wear a wide brimmed hat, UV protective sunglasses, and light and loose fitting clothing.
Be sure children are well hydrated. Plain water is the liquid of choice; diluted fruit juice is okay.
Check regularly on infants and young children to be sure they stay cool and hydrated.
Sunscreens/insect repellent are not recommended for infants under six months of age. Keep babies under one year of age out of direct sunlight.
Apply sunscreen (SPF 15 or higher) 20-30 minutes before going outside to ensure absorption.
When using DEET insect repellent, apply 20-30 minutes after sunscreen has been applied.
NEVER leave children in a closed parked vehicle.
Monitor children with disabilities and check the heat on metal and vinyl parts of wheelchairs.
Check heat of metal slides, monkey bars etc. in playground areas.
Staff should role model appropriate heat and sun safety behaviours for children.
Staff should be aware of signs and symptoms of heat cramps, heat exhaustion, and heat stroke. Follow first aid procedures promptly.
