By Chief Medical Officer Professor Dame Sally Davies.
As we have all felt, and the Met Office has warned, it would appear that winter has finally arrived this week.
During a cold spell, older people and those with underlying health problems, such as heart disease or respiratory conditions, can all be at higher risk of becoming ill.
Everyone should look after themselves this week and also keep an eye out for those around you.
If you are heading outside make sure you check your local weather forecast for the latest weather conditions and wrap up warm.
Icy conditions can make surfaces extremely slippery and older people should take extra care to avoid slips and falls.
If you do not want to brave the cold outside there are simple ways to keep warm at home, such as drawing curtains to block out draughts, drinking plenty of hot drinks, and wearing lots of light layers of clothing.
