Extreme Heat

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
