Heatwaves
In summer, or at other times of the year, it can get very hot. A heatwave means many days in a row of very hot weather.
Too much heat is dangerous for the body. It can cause:
- sunburn
- dehydration (the body does not have enough water)
- heat stroke
- sunstroke
- sleep problems
- accidents at work
- sometimes food poisoning, if food is no longer kept cold enough
When it is hot, the body reacts. We sweat more. Sweating helps the body stay at around 37 degrees.
As people get older, the body finds it harder to adjust to heat. Older people sweat less and feel less thirsty, even when their body needs water.
That is why older people need to take extra care during very hot weather
What should you eat and drink?
- Foods to prioritise: those that are high in water content, light and fresh
- Avoid: alcohol, caffeine, sugar and fatty foods
How can you keep your home cool?
In the morning: close the shutters, curtains and windows
In the evening (after 10 pm): Open the windows wide to create a draught
Is it too hot at home?
Look for a cool, air-conditioned place:
- Supermarkets
- Libraries
- Shopping centres
- Cinemas
How often should you drink?
- Golden rule: Every 20–30 minutes, 1 large glass per hour
- Don’t wait until you’re thirsty
- ‘Reminder’ tip – Set an alarm every 30 minutes, use a reminder app, or stick a Post-it note in a clearly visible place
