Does Sunlight Help Psoriasis?

Published in Psoriasis Treatment 2 mins read

Sunlight can provide relief from psoriasis symptoms. Many individuals with psoriasis notice improvement in their skin plaques during summer months or when living in sunnier climates.

How Sunlight Affects Psoriasis

Exposure to ultraviolet (UV) light, specifically UVB rays from sunlight, is known to help manage psoriasis. UVB light slows down the rapid skin cell growth characteristic of psoriasis. This reduction in cell turnover helps reduce the thickness and inflammation of psoriatic plaques, leading to clearer skin.

  • Improved Plaque Appearance: Many psoriasis sufferers report a lessening of redness, scaling, and itching after sun exposure.
  • Seasonal Improvement: A common observation is the improvement of psoriasis symptoms during the summer months with increased sunlight exposure.
  • Geographic Variations: People living in sunnier climates often experience milder psoriasis.

However, it's crucial to remember that overexposure to sunlight can be harmful. Sunburn can worsen psoriasis symptoms and increase the risk of skin cancer. Therefore, sun exposure should be carefully managed.

Safe Sun Exposure for Psoriasis

To reap the benefits of sunlight without risking harm, follow these guidelines:

  • Gradual Exposure: Start with short periods of sun exposure and gradually increase the duration.
  • Morning or Evening Sun: Opt for the less intense sunlight during morning or late afternoon.
  • Sunscreen Use: Even with therapeutic sun exposure, protecting your skin from sunburn is vital. Use a broad-spectrum sunscreen with an SPF of 30 or higher.
  • Consult a Dermatologist: Before relying on sunlight for psoriasis treatment, discuss it with a dermatologist. They can help determine the appropriate amount and type of sun exposure suitable for your condition.

Reference: Sunlight can offer relief for psoriasis symptoms, as many patients report improvement in their plaques in the summer months or if they live in sunny climates. (17-Aug-2023)
