Brits are freezing in bone-chilling lows of -3C as a cold weather health warning urges the public to stay warm and check on vulnerable friends and neighbours.
The UK Health Security Agency (UKHSA) has issued a cold weather health warning as the nation braces for freezing conditions over the next few hours.
An official advisory from the government agency is in place for all of England until 6pm on Tuesday. Temperatures will stay below freezing overnight in many areas tonight, with lows of -3C expected in the south and Midlands.
The elderly and those with certain health conditions have been asked to pay particular attention to the UKHSA warning and consider turning up their heating to at least 18C.
Dr Agostinho Sousa, Consultant in Public Health Medicine at UKHSA, said: "Cold weather can have serious consequences for health, with older people and those with heart or lung conditions particularly at risk.
"It’s important to check in on family, friends and relatives who are more vulnerable to the cold weather.
"If you have a pre-existing medical condition or are over the age of 65, it is important to try and heat your home to at least 18C if you can."
David Oliver, deputy chief forecaster at the Met Office, said the cold snap was the result of a dominant front of high pressure.
He commented: "This will bring some cold nights with a widespread frost across the country. However, by day temperatures will recover to around mid-single figures, near normal for the time of year."
