NHS staff have warned people to keep warm during the colder months to prevent a bout of the winter blues.

Oxfordshire NHS Primary Care Trust is reminding patients that it is not just colds and flu that become more common.

A lower body temperature can lead to depression, as well as an increased risk of heart and respiratory problems. Derys Pragnell, a PCT health improvement practitioner, said: "As the weather gets colder, many people turn the heating up and stay indoors. But the people who are most susceptible to ill health during the winter are often those living in housing least prepared for the cold.

"There are some simple measures we can all take to stay healthy, live well and keep warm in winter."

These include: Keep active during the day - try and move around at least once an hour and if you can do not sit for long periods of time.

When you are outside don't take risks - if it is wet or icy be careful not to fall, wear plenty of layers, and gloves and a hat.

When you are at home wear several thin layers of clothing and a hat or headscarf if you feel cold.

Remember "food is fuel", so eat regular hot meals and have a hot drink before bedtime.

Set your thermostat to about 21C for rooms you use during the daytime and heat your bedroom to least 18C overnight, or consider using a hot water bottle or electric blanket if your bedroom is cold.
