How cold weather affects your health

It's not just illnesses you need to protect yourself from in winter.

Winter weather can bring many risks to you and your family. There's the usual winter coughs, colds and flu, but then there's also risks to your health associated with flooding and storms.

Why is winter weather a risk to our health?

Older people, those with heart and lung conditions, dementia or Alzheimers, and very young children are at increased risk in colder weather. In particular, cold increases the risks of respiratory infections, heart attacks and strokes. Other health effects include poor mental health, worsening arthritis and increased accidents at home (associated with loss of strength and dexterity in the hands). THere are other risks in winter including physical injuries from slips, trips and falls.

As we get older it becomes harder for our bodies to detect how cold we are, and it takes longer to warm up.

Here's a video about how weather can affect our health and what you can do to manage the possible impacts.

Dealing with common winter illnesses

If you are normally healthy, many of the coughs, colds and minor illnesses that seem to happen more frequently during winter can be safely managed yourself. There's plenty of advice about dealing with common winter illnesses from NHS on their Stay well this winter website and you can also talk to your local pharmacist. We also have a page about the Norovirus.


Flu affects people in different ways. If you are healthy you will usually shake it off within a week. Flu vaccination is offered free of charge on the NHS to people who are at most at risk from the effects of flu. This is to protect them from catching flu and developing serious complications. Find out who is eligible for a free flu jab.

Contact your GP or pharmacist if you think you, or someone you care for, should be eligible for a free flu jab. There's further information about flu and the flu vaccine on the flu pages of the NHS Choices website.

Keeping yourself warm at home in winter

  • Keep warm - if you get cold, especially if you are over 65, can trigger a rise in blood pressure which puts you at risk of a heart attack.
  • Remember that several thin layers of clothing will keep you warmer than one thick layer, as the layers trap warm air.
  • Wear warm clothes in bed. When very cold, wear thermal underwear, bed socks and even a hat - a lot of heat is lost through your head.
  • Read more tips about keeping your house warm and find out about the ideal room temperatures for your home.
  • Prepare for cold weather - listen to the forecast and make sure you have everything you need before the weather turns cold or icy.

Keep warm to keep well - get moving!

It's important to stay active as this generates heat and helps to keep you warm. Try to keep moving when you're indoors, and don't sit still for more than an hour. If walking is difficult, you can do chair-based exercises. Even simply moving your arms and legs and wiggling your toes will get your circulation going.

Eating well in winter      

It's important to make sure you (or someone you care for, or visit) eats enough in winter. Hot meals and drinks will help to keep you warm. Follow Age UK's tips to keep you eating well this winter:

  • Try to eat at least one hot meal each day and have hot drinks during the day.
  • Include a good range of foods in your diet and aim for five portions of fruit and vegetables each day, so that you're getting plenty of nutrients and vitamins. Remember that frozen vegetables are just as good as fresh.
  • If you're worried about a poor appetite, speak to your GP.
  • Have a hot drink before bed and keep one in a flask by your bedside.

Cold weather alerts for healthcare professionals

The Met Office issues Cold Weather Alerts on our website and these are sent directly to social and healthcare services in England, and to Age UK. These alerts ensure that staff are fully prepared for any cold weather periods.

Public Health England produces a Cold Weather Plan for England which helps to raise awareness of the harm to health from cold, and provides guidance on how to prepare for and respond to cold weather.
