Heat illnesses are preventable.
While heat can put everyone at risk from heat illnesses, health risks are greatest for:
- older adults;
- infants and young children;
- people with chronic illnesses such as breathing difficulties, heart conditions or psychiatric illnesses;
- people who work in the heat;
- people who exercise in the heat;
- homeless people; and
- people without access to air conditioning.
Watch for symptoms of heat illness, which include:
- dizziness or fainting, nausea or vomiting
- headache
- rapid breathing and heartbeat
- extreme thirst and
- decreased urination with unusually dark yellow urine.
If you experience any of these symptoms during a heat event, immediately move to a cool place and drink liquids. Water is best.
Frequently visit neighbours, friends and older family members, especially those who are chronically ill, to make sure that they are cool and hydrated.
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.
Please continue to monitor alerts and forecasts issued by Environment Canada.
