The beauty of parks and gardens, bird songs, and of course, the heat from the sun helps to reenergize us before the return of Old Man Winter. Heat is usually revitalizing, but it can become oppressive when the thermometer spikes and the humidity sets in.
When weather forecasts project temperatures of at least 30°C and a humidex (combination of temperature and humidity in a single measure to reflect the temperature perceived) of 40°C or more, Environment Canada issues a Heat Warning. In this case, we speak of oppressive heat or a heat wave, which present a danger to health, especially for babies and for the elderly.
Due to global warming, periods of oppressive heat are more and more frequent, prolonged, and intense. Extreme heat also means risk of dehydration. Other than symptoms such as dry mouth, hypotension, and muscle cramps, dehydration due to overexposure to extreme heat can cause heatstroke.
Heatstroke occurs when the body overheats and is unable to cool down. This can cause fever, headache, dizziness, fainting, and in the worst cases, death.
