WATCH: Precautions to take while staying cool in the water this summer
To beat the heat, Environment Canada says you should drink plenty of water, even before feel thirsty, and stay in a cool place.
You should also watch for symptoms of hear illness, which include dizziness, nausea, rapid breathing and heartbeat, extreme thirst, or decreased urination with unusually dark urine.
Heat warnings are issued when very high temperature or humidity conditions are expected to pose an elevated risk of heat illnesses, such as heat stroke or heat exhaustion.
