Extreme Heat and Heat-Related Illnesses
We have had some hot days this summer! It is important to remember that extreme heat and heat-related illnesses are especially dangerous for infants and young children.
The Middlesex-London Health Unit issues an extreme weather alert when Environment Canada’s heat warning criteria are met. These criteria are a daytime temperature of 31oC or higher with a nighttime low of 20oC or higher, OR a humidex of 40 or higher, for two or more consecutive days. Due to climate change, there may be an increase in instances of extreme heat and heat-related sickness.
Heat-related illnesses can present with symptoms such as:
- Dizziness or fainting
- Nausea or vomiting
- Headache
- Rapid breathing and heartbeat
- Extreme thirst (dry mouth or sticky saliva)
- Changes in behaviour (like sleepiness or temper tantrums)
- Decreased urination with unusually dark yellow urine
To help protect your children and yourself, drink water frequently without waiting to feel thirst. If you don’t have air conditioning in your home, seek air-conditioned buildings in the community to provide comfort during the heat of the day (e.g. cooling centres, community centres, libraries). When outdoors, wear breathable, light-coloured clothing and a wide-brimmed hat, and restrict physical activity to the coolest time of the day. Spray/splash pads are available, free of charge, in many neighbourhoods and communities, which inspire summer fun, while providing cooling relief. Don’t forget to apply plenty of sunscreen with SPF 30 or more, labelled ‘broad spectrum’ and ‘water resistant’, and reapply, especially after splashing and towelling. Sunscreen may be used on babies over six months of age; avoid the mouth and eye areas.
