With the forecast of cold weather and some freezing fog patches for parts of England, Public Health England (PHE) is urging people to prepare for cold weather conditions and look out for those most at-risk.
The Met Office has announced that there is a high chance that South West England will experience cold weather from 6pm on Sunday 19 January to 6pm on Tuesday 21 January.
Dr Owen Landeg, Principal Environmental Public Health Scientist at Public Health England, said:
Older people and those with heart and lung problems are at risk of getting sick in cold weather.
Keep an eye out for those who may need help staying warm, ensure they wear lots of thin layers and have everything they need.
Below 18 degrees, changes to the body mean that the risk of strokes, heart attacks and chest infections increase so heating homes to this temperature is particularly important to stay well.
Nick Silkstone, Deputy Chief Meteorologist at the Met Office said:
High pressure is in place across the UK this weekend bringing settled, mainly dry, but also cold weather for many. It will be colder than of late with temperatures dropping below freezing overnight and a chance of widespread frost but with sunny spells throughout the day.
