Does psoriasis flair up in a cold damp climate?
Cold has been known to be a trigger.
There are environmental triggers for psoriasis- cold dry weather can trigger a flare up.
Moisture or dampness has not been shown so far to be a trigger but as mentioned, a cold environment can trigger symptoms.
During winter there is also less exposure of the skin to sunlight since persons would naturally wear more clothing.
Short term exposure to sunlight, which has been shown to be helpful, would therefore be reduced.
I hope this helps.
