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
Heatwave action Advice: Look out for others, especially older people, young children and babies and those with underlying health conditions. Close curtains on rooms that face the sun to keep indoor spaces cooler and remember it may be cooler outdoors than indoors. Drink plenty of fluids and avoid excess alcohol, dress appropriately for the weather and slow down when it is hot.
Advice on how to reduce the risk can be obtained from the Heatwave Plan for England page, from your doctor or local chemist, or ring NHS 111.
