Knee Osteoarthritis: Why Winter Can Make It Worse — and How to Manage It

Do your knees feel stiffer and more achy in the colder months? You’re not imagining it. Many people with knee osteoarthritis (OA) notice their symptoms flare up in winter. The good news is that there are safe, effective ways to manage your pain and keep moving.

Knee osteoarthritis is a condition where the space in your knee joint gradually reduces over time.

This can cause:

  • Pain and stiffness
  • Swelling
  • Difficulty moving freely

It’s more common as we age or after injuries, but not everyone develops symptoms. For some people, OA can be mild and manageable, while for others it may feel more limiting.

Yes. In fact, exercise is one of the best treatments for OA.

Staying active helps:

  • Strengthen the muscles that support your knee joint
  • Improve flexibility and mobility
  • Reduce pain and stiffness

Low-impact activities such as walking, swimming, or cycling are excellent choices. Even better is a physiotherapist-led programme, which gives you safe, targeted exercises tailored to your needs. The key is balance: staying active without overloading your joints.

An osteoarthritis flare-up is when symptoms suddenly get worse, causing increased pain, stiffness, or swelling. These flare-ups can last for a few days or even weeks.

Common triggers include:

  • Cold weather
  • Overuse or changes in activity
  • Stress

During a flare-up, complete rest isn’t always the answer. Gentle movement, stretching, pain relief strategies, and sometimes physiotherapy can all help calm things down until symptoms settle.

Cold weather can make joints feel more stiff, but there are steps you can take:

  • Keep moving with low-impact exercise
  • Stay warm with layers and heat packs
  • Pace your activity, don’t do too much, too soon
  • Book a physiotherapy session for tailored advice and support

Living with knee osteoarthritis doesn’t mean giving up the activities you love. With the right treatment plan, including exercise, flare-up management, and professional guidance, you can reduce pain, improve mobility, and feel more confident in your movement.
