Sunlight Can Help Your Psoriasis

Skin Information .COM

Psoriasis is a common and chronic disorder where the skin becomes thickened, scaly, and red, causing itchiness, drying, and sometimes pain. The extent varies largely, and can be specific or general and widespread. An immunological disorder is at the heart of psoriasis, causing cells which defend the body from pathogens to become overactive, which has the effect of permanently modifying the skin. Normally, it takes 28 days for the skin to generate and shed, however in psoriatic patients, this takes 4 days, resulting in the piling of new skin, creating the scale in the skin.

UVB light from exposure to sunlight can help your psoriasis condition. This light causes the skin to burn, and it’s this effect that has the side benefit of healing psoriasis. However, proper skin care needs to be exercised, even if you find that sunlight does help your psoriasis. UVB lights also have the negative effect of burning your skin. In addition, it reduces your skin’s immunity. The sun also produces UVA lights which can cause wrinkles, and increase your risk of skin cancer.

If you choose to go out into the sun as a part of psoriasis treatment, we recommend taking the following precautions:

  • Protect areas unaffected by psoriasis well with sunscreen.
  • Wear sunscreen that protect from both UVA and UVB light, with an SPF of 30 or more.
  • Anytime sun exposure for more than 20 minutes is expected, sunscreen should be applied.
  • If you have dry skin, apply sunscreen 15 to 30 minutes before exposure to sunlight.
  • Reapply sunscreen every 2 hours, or after swimming or other strenuous activity that causes sweating.
  • Wear sunglasses which filter both UVA and UVB light.

Experts recommend meticulous record keeping to note the effects of exposure to sunlight. Sunbathe three times a week, and keep a record of the time of day, and exposure time. Understand that it can take several weeks before improvement can be seen, and remember that overexposure can also be harmful for your skin, causing flare ups.
