Heatwave
A heatwave is any long period of very hot weather, usually ranging from 37°C to 42°C.
During heatwaves, there is an increase in emergency calls from people suffering heat-related illnesses. While the very young and the elderly are most at risk, anyone can be affected.
Heat-related illness occurs when the body absorbs too much heat. This may happen slowly over a day or two of very hot weather. Act quickly to avoid serious—or even fatal—effects of fully developed heat stroke.
Early signs of heat stress:
- rising body temperature
- dry mouth and eyes
- headache
- shortness of breath
- vomiting
- absence of tears when crying.
