For the majority of people it is about common sense - staying cool, drinking plenty of water to maintain hydration, and avoiding sunburn. However, some groups can be particularly vulnerable and at much greater risk of harm, especially those with underlying heart and lung conditions, older people, babies and young children.
Looking out for people in these groups is important while most of England swelters under high temperatures.
The top ways for staying safe when the heat arrives are to:
- 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 water as sugary, alcoholic and caffeinated drinks can make you more dehydrated
- never leave anyone in a closed, parked vehicle, especially infants, young children or animals
- try to keep out of the sun between 11am to 3pm
- take care and follow local safety advice, if you are going into the water to cool down
- walk in the shade, apply sunscreen and wear a hat, if you have to go out in the heat
- avoid physical exertion in the hottest parts of the day
- wear light, loose fitting cotton clothes
- make sure you take water with you, if you are travelling
