What are you asking — what does the sun do to psoriasis?

The sun can often improve psoriasis symptoms by reducing inflammation and slowing down skin cell growth. However, overexposure to the sun can also exacerbate psoriasis or cause a flare-up.

So let’s look deeper

The sun can often improve psoriasis symptoms by reducing inflammation and slowing down skin cell growth through the action of ultraviolet (UV) radiation. The National Psoriasis Foundation explains that “when skin cells die, an inflammatory response occurs that involves T cells and other immune system cells. UVB radiation can reduce the number of T cells in the skin, as well as their ability to function. High-intensity UVA light can suppress active immune system cells in the skin and blood.” However, it is important to note that overexposure to the sun can also exacerbate psoriasis or cause a flare-up.

According to a study published in the Journal of Photodermatology, Photoimmunology & Photomedicine in 2018, “for many patients, sunlight represents the single most effective and easily accessible treatment option for psoriasis. In fact, sunlight is even more cost-effective than phototherapy.” This study also found that “sunlight exposure has a superior effect on psoriasis compared to phototherapy devices in terms of duration of effect and plaque clearance.”

It is recommended that people with psoriasis approach sun exposure with caution and under medical guidance. The National Psoriasis Foundation suggests starting with brief, small doses of natural sunlight and avoiding peak hours of sun exposure. They also recommend using sunscreen on unaffected skin and avoiding sunburn.

In a quote from Dr. Richard G. Fried, a board-certified dermatologist and clinical psychologist, he explains that “sun exposure can be a double-edged sword for people with psoriasis. On one hand, exposure to the sun can promote the production of vitamin D, which can improve the immune system, and help fight off infections. However, too much sun exposure can lead to sunburn, and worsening of psoriasis symptoms.”

Here is a table of interesting facts about psoriasis and sun exposure:

Fact Explanation

Sunlight is a natural source of vitamin D Vitamin D can be beneficial for people with psoriasis and its deficiency has been linked to an increased risk of autoimmune diseases
Sunburn can trigger psoriasis flares Overexposure to sun can cause skin irritation and inflammation that can lead to worsening of psoriasis symptoms
Ultraviolet B radiation is the most effective type of UV radiation for psoriasis treatment UVB therapy is a type of light therapy that can help control psoriasis symptoms
Tanning beds should be avoided by people with psoriasis Tanning devices can cause even more harm than natural sunlight, and studies have shown that they may increase the risk of skin cancer

In conclusion, while the sun can have a beneficial effect on psoriasis, it is important for people with psoriasis to be cautious when approaching sun exposure. Consulting with a medical professional and following recommended guidelines can help individuals with psoriasis safely enjoy the benefits of natural sunlight.

The reason why sunlight is powerful is due to its UVB rays. Sunlight is composed of ultraviolet light, consisting of UVA and UVB rays. The UVB rays slow the rapid rate of skin growth that appears as psoriasis. Ultraviolet light is so powerful in easing psoriasis symptoms that it’s used in phototherapy.
