How to keep cool during the heatwave

Keep out of the heat

If a heatwave is forecast, try and plan your day in a way that allows you to stay out of the heat.
If you can, avoid going out in the hottest part of the day (11am-3pm).
If you can't avoid strenuous outdoor activity, like sport, DIY, or gardening, keep it for cooler parts of the day, like early morning.
If you must go out, stay in the shade. Wear a hat and light, loose-fitting clothes, preferably cotton. If you’ll be outside for some time, take plenty of water with you.

Stay inside, in the coolest rooms in your home, as much as possible.
Close the curtains in rooms that get a lot of sun.
Keep windows closed while the room is cooler than it is outside. Open them when the temperature inside rises, and at night for ventilation. If you are worried about security, at least open windows on the first floor and above.
Take cool showers or baths, and splash yourself several times a day with cold water, particularly your face and the back of your neck.

Drink regularly even if you do not feel thirsty – water and fruit juice are best.
Avoid tea, coffee and alcohol as they can cause dehydration.
Eat as you normally would. Try to eat more cold food, particularly salads and fruit, which contain water.
