Older people and people with heart, respiratory and other serious health problems are most vulnerable when the temperature starts to rise.
The main risks posed by a prolonged spell of hot weather, or a heatwave, are:
Signs of illness
Seek help from a GP or contact NHS 111 if someone is feeling unwell and shows symptoms of:
- chest pain
- intense thirst
- cramps which get worse or don't go away
Ways to stay well in the heat include:
- staying out of the sun and don't go out between 11am and 3pm (the hottest part of the day) if you're vulnerable to the effects of heat
- ensuring adequate ventilation
- wearing loose, cool clothing, and a hat and sunglasses if you go outdoors
- shutting windows and pulling down blinds when it is hotter outside - you can open the windows for ventilation when it is cooler
- drinking regularly - water or fruit juice is best and avoid excess alcohol, caffeine (tea, coffee and cola) or drinks high in sugar
- keep rooms cool by using shades or reflective material outside the windows - if this isn't possible, use light-coloured curtains and keep them closed (metallic blinds and dark curtains can make the room hotter)
- have cool baths or showers, and splash yourself with cool water
Other ideas for staying safe in the sun include:
- listen to alerts on the radio, TV and social media about keeping cool
- plan ahead to make sure you have enough supplies, such as food, water and any medications you need
- identify the coolest room in the house so you know where to go to keep cool
- check up on friends, relatives and neighbours who may be less able to look after themselves
If you have any concerns contact your GP for further advice.
