Does sunbathing really have a therapeutic effect on psoriasis? " sunbathing " can really make the skin lesions subside without any medication?
UV treatment for psoriasis
UV is divided into three bands: long-wave , medium-wave and short-wave, corresponding to UVA, UVB and UVC:
100-290nm is short-wave ultraviolet (referred to as UV for short): C)
290-320nm is medium wave ultraviolet ray (UVB for short)
320-400nm is long wave ultraviolet ray (UVA for short)
Generally speaking, short wave ultraviolet rays in sunlight cannot reach the ground, while medium wave ultraviolet rays and long wave ultraviolet rays can reach the surface of the earth and act on the skin during sunbathing. Ultraviolet rays clinically used in psoriasis treatment are narrow spectrum medium-wave ultraviolet and long-wave ultraviolet combined with psoralen (PUVA). In dermatology phototherapy treatment and during sunbathing, appropriate ultraviolet radiation can play a therapeutic role in psoriasis.
Excessive ultraviolet radiation can cause skin diseases
Excessive ultraviolet radiation can cause skin damage. In the adverse aspects of ultraviolet rays, UVB mainly accumulates on the skin surface, causing epidermal cells to atrophy, apoptosis, and even form lesions. UVA can damage the fibrous structure of dermal tissue, cause collagen to be lost, skin elasticity weakens, and cause skin aging. In addition, sun exposure may also cause or aggravate certain skin diseases, such as sunburn , sunburn , photosensitive dermatitis, lupus erythematosus , etc.
How to correctly bask in the sun in patients with psoriasis
Silver friends can enhance the body's immunity by appropriate basking in the sun, reducing the inflammation caused by psoriasis to a certain extent, and also helping blood circulation. Since proper sunbathing is good for the body, how can we dry it correctly?
First of all, sunbathing for psoriasis is divided into full-body sunbathing and local sunbathing. Usually, patients with large-area lesions can choose full-body sunbathing, while patients with small-area can choose local sunbathing and choose severity of skin lesions.
Secondly, be sure to choose the right time. It is recommended to choose early mornings and evenings with less intense sunshine.
In addition, the sun exposure time should not be too long. Generally, it takes 20-30 minutes at a time, not more than 2 hours to avoid chronic skin damage.
Psoriasis is a recurrent disease, so silver friends should still insist on taking medicine and never stopping the medicine without authorization. Appropriate sunbathing can only be used as an auxiliary means to treat psoriasis and cannot replace formal treatment!
