Heatwave: how to cope in hot weather
Many 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. When hot weather hits, 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
Who's most at risk?
A heatwave can affect anyone, but some people are more vulnerable, including:
- older people, especially those aged 65 and over
- babies and young children aged 5 years and under
- people who have serious long-term conditions – such as heart problems, breathing problems, dementia, diabetes, kidney disease, Parkinson's disease, mobility problems, mental health problems, or drug or alcohol addiction
- people who live alone and may be unable to care for themselves
- people who are on multiple medicines or medicines that may make them more likely to be badly affected by hot weather
- people who are already ill and dehydrated (from diarrhoea and vomiting, for example)
- people who are homeless, or who work or spend a lot of time outside, particularly if they're physically active, such as runners, cyclists and walkers
- people whose jobs involve manual labour
Tips for coping in hot weather
Keep out of the heat if you can. If you have to go outside, stay in the shade especially between 11am and 3pm, wear sunscreen, a hat and light clothes, and avoid exercise or activity that makes you hotter.
Cool yourself down. Have cold food and regular cold drinks. Drink extra fluids but avoid alcohol, caffeine and hot drinks, and have a cool shower or put cool water on your skin or clothes.
Keep your living space cool. Close windows, curtains and blinds during the day and open them at night when the temperature outside has gone down. Electric fans can help if the temperature is below 35 degrees.
Check the temperature of rooms, especially where people at higher risk live and sleep, and make sure to check on anyone who is at higher risk from the heat.
You can also get help from the environmental health office at your local council, if you think a hot house is affecting your health or someone else's. They can inspect a rented home for hazards to health, including excess heat.
Watch out for signs of heat-related illness
If you or someone else feels unwell with a high temperature during hot weather, it may be heat exhaustion or heatstroke.
