A heat wave is an extended period of extreme heat, often accompanied by high humidity. Prolonged periods of high temperatures and high humidity can be very dangerous for your health as evaporation is slowed and your body has to work very hard to maintain a normal temperature.
The main risks posed by a heatwave are:
Dehydration (not having enough water)
- overheating, which can make symptoms worse for people who already have problems with their heart or breathing
- heat exhaustion
- heatstroke
But there are some ways to keep yourselves cool and comfortable and reduce the impact of these adverse heat waves.
