If a heatwave hits this summer, make sure the hot weather doesn't harm you or anyone you know.

There are many risks posed by a heatwave, these are:

• Dehydration (not having enough water)
• Overheating, which can make symptoms worse for people who already have problems with their heart or breathing
• Heat exhaustion and heatstroke

Who is most at risk?

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. If it's safe, open them 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.
