Most of us welcome hot weather, but when it’s too hot for too long there are health risks. Make sure the current heat wave doesn’t harm you or anyone you know.
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 and heatstroke
A heatwave can affect anyone, but the most vulnerable people are:
- older people, especially those over 75
- babies and young children
- people with a serious chronic condition, especially heart or breathing problems
- people with mobility problems – for example, people with Parkinson’s disease or who have had a stroke
- people with serious mental health problems
- people on certain medications, including those that affect sweating and temperature control
- people who misuse alcohol or drugs
- people who are physically active – for example, labourers or those doing sports
