Hot weather is uncomfortable but usually does not result in heat related illness, while periods of extreme heat are proven to affect the health of residents. Humidex readings below 40° C can cause discomfort but do not usually result in heat related illnesses. When conditions exceed this, an Extreme Heat Alert may be declared by the Windsor-Essex County Health Unit.
In extreme heat:
- Stay out of the sun. If you must be in the sun, wear sunscreen (at least SPF 15).
- Avoid overexertion and strenuous outdoor activities.
- Wear lightweight, light-coloured, loose-fitting clothes that cover as much skin as possible to prevent sunburn.
- Consume plenty of non-alcoholic, non-caffeinated fluids. Water, diluted juices and electrolyte solutions are best. Stay away from carbonated drinks.
- Avoid alcohol.
- If you are on a fluid-restricted diet or taking diuretics, consult your doctor
- Stay in the shade or under awnings as much as possible.
- Keep rooms well ventilated with air conditioners and/or fans. Keep your windows open if you don't have a fan or air conditioning.
- Cool down with periodic cool baths or showers.
- Take advantage of air-conditioned city recreation facilities, public pools and air-conditioned stores and malls.
- Never leave children, the elderly, or those who require special care during periods of intense summer heat.
- Make a special effort to check on your neighbours during a heat wave, especially if they are seniors, young children, and people with special needs or living alone.
- Seniors and others who may be sensitive to extreme heat should contact friends, neighbours, or relatives periodically throughout the day.
- Seek help if you feel symptoms of heat-related illnesses
