How to stay safe during hot weather

The heatwave is expected to last for most of the week

Temperatures are set to rise this week as the heatwave in the UK returns.

And while some people may love the sunshine and warmth, for others it can be a dangerous time.

A level 3 alert has been issued by the Met Office and Public Health England with temperatures set to stay high until Friday.

The NHS says the main risks posed by a heatwave are dehydration; overheating and heat exhaustion and heatstroke.

Heatwaves can affect anyone but people most at risk 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

The NHS has issued the following tips for people to stay cool during 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.
