Heatwave: how to cope in hot weather

Most of us welcome hot weather, but when it's too hot, there are health risks. During heatwaves, more people than usual get seriously ill or die. If hot weather hits this summer, make sure it does not harm you or anyone you know.

Why is a heatwave a problem?

The main risks posed by a heatwave are:

  • not drinking enough water (dehydration)
  • overheating, which can make symptoms worse for people who already have problems with their heart or breathing
  • heat exhaustion and heatstroke
