“Thinking ahead about your eating, drinking and exercise habits can also make a big difference,” says Miranda. “Eating at least one hot meal a day and topping up with hot drinks will insulate the body against the cold, and exercise is also an effective energy booster.”

Make sure you’re eating a variety of staple foods such as bread, cereals, dairy products, fruit and veg, meat, fish, eggs and pulses. Although it’s good to include some fat and sugar, limit your intake unless you are underweight or unwell.

Remember to keep your cupboard well stocked in case you have difficulty getting out to the shops because of bad weather, adds Miranda.

It’s also important to keep your fluid levels up. “You should be aiming to drink between six and eight glasses or cups of liquid a day. It might also be a good idea to prepare a thermos flask of a hot drink to have by your bed in case you wake up in the night feeling cold,” says Miranda.
