The main risks posed by a heatwave are:
-
dehydration (not having enough water)
-
overheating, which can make symptoms worse for people who already have problems with their heart or breathing
A heatwave can affect anyone, but the most vulnerable people are:
-
older people, especially those over 75
-
babies and young children
-
people with a serious chronic condition, especially heart or breathing problems
-
people with mobility problems – for example, people with Parkinson's disease or who have had a stroke
-
people with serious mental health problems
-
people on certain medications, including those that affect sweating and temperature control
-
people who misuse alcohol or drugs
-
people who are physically active – for example, labourers or those doing sports

Tips for coping in hot weather
-
Shut windows and pull down the shades when it is hotter outside. You can open the windows for ventilation when it is cooler.
-
Avoid the heat: stay 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.
-
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.
-
Drink cold drinks regularly, such as water and diluted fruit juice. Avoid excess alcohol, caffeine (tea, coffee and cola) or drinks high in sugar.
-
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.
-
Wear loose, cool clothing, and a hat and sunglasses if you go outdoors.
-
Check up on friends, relatives and neighbours who may be less able to look after themselves.

If you're worried about yourself or a vulnerable neighbour, friend or relative, you can contact the local environmental health office at your local authority.
Environmental health workers can visit a home to inspect it for hazards to health, including excess heat. Visit GOV.UK to find your local authority.
