How weather affects psoriasis
Not every weather factor hits every condition the same way. These are the inputs our Psoriasis scoring model weighs most heavily — and in Seattle (West Coast), they interact with the local climate pattern: Seattle, San Francisco, and Los Angeles — Pacific coast weather trends and body-forecast scores.
Humidity
30% of scoreLow humidity dries skin and disrupts the skin barrier, triggering psoriasis flares; moderate humidity keeps plaques hydrated.
UV exposure
30% of scoreModerate UV exposure (especially UVB) is therapeutic for psoriasis, slowing keratinocyte proliferation, but sunburn can trigger the Koebner response.
Temperature
15% of scoreCold weather worsens psoriasis through skin drying and reduced UV exposure; warm weather generally improves symptoms.
Air quality
15% of scoreAir pollutants can trigger oxidative stress in the skin and exacerbate inflammatory pathways involved in psoriasis.
Wind
10% of scoreWind accelerates skin moisture loss and can carry irritants that aggravate exposed psoriasis plaques.
