THE NHS has warned Brits not to go outside in the morning or evening after health alerts were issued for the whole of England amid a -8C freeze.
Public health bosses have issued amber alerts for the whole of England from now until January 8.
The UK Health Security Agency warned a rise in deaths is likely, particularly among the elderly and people with health problems.
NHS bosses in the West Midlands have warned locals not to go out early in the morning or late at night, when frost will be thick.
They said people should keep hands free and wear shoes with a good grip.

Yesterday London councils activated an emergency accommodation protocol for people sleeping rough in freezing conditions.
The emergency measures, which see extra beds made available, have been active for three nights so far this winter.
Last night the mercury sank as low as minus 8C in rural Scotland and northern England.
A yellow warning for snow will be in force from noon tomorrow until 9am on Monday.
The warning covers all regions of England, other than the south west, most of Wales and parts of southern Scotland.
Around 2 inches of snow is expected widely across the Midlands, Wales and northern England.
A whopping 16 inches could fall over high ground in Wales and the Pennines, the forecaster added.
Strong winds could lead to snow drifts in some areas, and freezing rain as temperatures creep up could add to the risk of ice.
Met Office meteorologist Tom Morgan said: “At the moment we’ve issued a very large snow warning for Saturday until Monday.
“But it doesn’t mean that everywhere within that warning could see snow, it’s just a heads-up there could be some impacts.”
The Met Office has warned people to be prepared and aware when travelling with longer journey times likely.
Railways are likely to experience delays or cancellations, with National Rail confirming that various routes across the UK are impacted.
Poor weather is currently affecting National Rail’s Northern and ScotRail services.
In Wales, buses are replacing trains between Llandudno Junction and Blaenau Ffestiniog.
There could be icy surfaces in northern and western Scotland, the north west of England and Northern Ireland.
Motorists and pedestrians alike are warned to be wary of icy patches on untreated roads, pavements, or cycle paths.
A major incident declared in Greater Manchester on Wednesday because of flooding has been stood down.
Emergency services and partners now focusing on recovery efforts and there have been no casualties or reports of serious injuries.
Conditions should become a little warmer over the weekend before cold snap sets in again early next week.
Met Office expert Dan Stroud said: “The second half of the weekend should be in the high singles or low doubles.
“But temperatures will dive again next week, particularly on Monday and Tuesday.
“They should start to improve towards the latter end of the week – but there’s a lot of water to go under the bridge until then.”
Age UK chief Caroline Abrahams said pensioners will struggle in the cold snap after the government slashed the winter fuel allowance.
Ms Abrahams said OAPs had already contacted the charity “worrying about what to do when this moment arrived”.
She said said: “We urge older people to do everything they can to stay warm.
“Even if that means risking spending more on their heating than they feel they can afford.
“The energy companies are under an obligation to help if you are struggling.”
Abrahams added: “There may be support available from your local council too.”
From this winter, only people on pension credit or certain other benefits will receive the winter fuel payments.
More than nine million others are set to be stripped of the allowance under the new rules.
