Seasonal skin and psoriasis

Many people tell us their psoriasis or psoriatic arthritis changes with the seasons, with some finding that cold, dry weather makes skin drier and itchier, while others struggle more with heat, sweat or sun exposure. Research suggests that around half of people with psoriasis notice little seasonal change, but a significant proportion report improvement in summer and worsening in colder months, while a smaller group do better in winter.

Seasonal patterns are thought to be linked to factors such as dry air, indoor heating, reduced natural sunlight, sudden temperature changes and, for some, sunburn or time spent in air conditioning. Studies also highlight that weather “trends” (for example, cooling periods) may influence disease activity and treatment response in certain groups, such as people with a higher BMI, showing that seasonal effects can be quite individual.

If you’ve noticed seasonal changes, you may find it helpful to explore our practical information on skin care, triggers and self‑management throughout the year. You can find tips on moisturising, bathing, clothing, sun protection and managing flares here:

Everyone’s psoriasis and psoriatic arthritis is different, so seasonal advice needs to be tailored to you. If you notice a sudden change in your skin or joints, or if you are unsure how to adapt your treatment or daily routine around the seasons, please speak to your GP, dermatologist or rheumatologist for individual medical advice.
