Why Your Psoriasis Might Be Getting Worse Right Now — and What Can Help

If you've noticed your skin or joints flaring in the last few days, you're not imagining it. A noticable cold snap has hit much of the UK this week, with overnight temperatures dropping below 10°C across England and Wales — and for many people living with psoriatic disease, that shift in the weather is enough to set things off.

This is one of the most common questions we hear in our community at this time of year: why does autumn make everything worse? So here's what's actually happening and what might help.

What changes in autumn affect psoriatic disease

Several things happen at once as the season turns, and they stack.

Less UV light. Summer sunlight has a well-established dampening effect on psoriasis for many people. As daylight shortens and the sun sits lower in the sky, that natural source of relief disappears almost overnight. For those who found their skin calmer over the summer, this transition can be abrupt.

Colder, drier air. Cold air holds less moisture than warm air. Once heating systems come on indoors, the air gets even drier. Skin that was managing reasonably well can start to dry out quickly — and for psoriasis, dry skin is a fast route to irritation, cracking, and flares. The itch-scratch-flare cycle is harder to break when the air itself is working against you.

Layers and fabrics. Jumpers, thermals, and tighter clothing can rub against affected areas, and some fabrics (particularly wool) are known irritants for sensitive psoriatic skin. The same clothing that keeps you warm can quietly worsen skin symptoms.

The Koebner response. Psoriasis has a well-known tendency to appear at sites of skin injury or irritation — a phenomenon called the Koebner response. Chapping, cold wind on exposed skin, and even the friction of wearing more clothing can all trigger new patches in people prone to it.

Stress and the seasons. Autumn can bring its own emotional weight: darker mornings, less time outdoors, the end of a summer that might have offered some relief. For many people in our community, stress is one of the most reliable flare triggers — and the shift into autumn can bring plenty of it.

Practical things that tend to help

None of this is medical advice, and everyone's psoriatic disease is different. But these are the things our community returns to most consistently as the cold sets in:

Moisturise more, and more often. Switching to a thicker emollient as autumn arrives — rather than a lighter summer lotion — makes a real difference for many people. Apply it to damp skin after bathing when you can.

Keep indoor heating moderate. Central heating dries air significantly. A humidifier, or even a bowl of water near a radiator, can help offset that.

Choose your layers carefully. Cotton and soft fabrics next to the skin tend to cause less irritation than wool or synthetics directly against affected areas.

Protect exposed skin outdoors. Gloves, scarves, and covering up in cold wind can reduce Koebner triggers on hands and other exposed areas.

Talk to your GP or dermatologist before winter sets in. If you know autumn is your difficult season, early contact — rather than waiting for a bad flare — gives you more options.

You don't have to manage this on your own

Seasonal flares are one of the things our community talks about most in the PSOcial Space, our peer support community on Discord. People who've been through many autumns with psoriatic disease share what's worked for them, what hasn't, and sometimes just the knowledge that someone else understands.

If you're new to psoriatic disease or trying to make sense of what's happening with your skin or joints right now, our Information Hub covers psoriasis and psoriatic arthritis in clear, plain language — written by people with lived experience and informed by NHS guidance.

And if you want to connect with others in real time, you're welcome in the PSOcial Space: psocial.psor.org.

This time of year can be hard. We're here through it.
