Serotonin is a brain chemical that helps to boost good mood to help in feeling calm and stay focused. Serotonin release is essential because it causes the effect melatonin a hormone the brain releases when it becomes dark to trigger sleepiness. Low or failure to get exposure to sunlight causes dipping of serotonin levels. Low levels of serotonin increase the risk of getting seasonal affective disorder(SAD) a form of depression that occurs due to change in seasons.
Light therapy also phototherapy is one of the treatments for SAD. A doctor recommends the use of customized lightbox that stimulates the brain to make serotonin hormone to reduce production of excess melatonin. Exposure to sunlight provides natural sunlight to aid in the production of serotonin. Exposure to sunlight helps in treating panic attacks, anxiety-related disorders which have links with reduced sunlight and changing seasons. Other medical conditions that the sun helps in treating non-seasonal depression and premenstrual dysphoric disorder.
Alleviation of Bone Problems
Exposure to sunlight helps in the production of vitamin D that plays an essential role in bone health.

The sun helps in building healthy bones by providing ultraviolet -B radiation that enables the skin to create vitamin D.

Treatment of Psoriasis
Psoriasis is a chronic skin infection occurring when the immune system produces extra skin cells that accumulate on its surface. When the skin cells begin shedding, they form thick red raised welts which are painful or itchy.
UVA and UVB rays make up the sun ultraviolet rays. Doctors use UVA or UVB for treatment method called phototherapy using natural or artificial light. UVB rays have more capacity in treating symptoms of psoriasis by slowing the rapid rate at which the skin grows and sheds. The skin absorbs ultraviolet rays through the skin during sunbathing or a special light box. It provides better results when a doctor administers it within specific time on the regular schedule. Treatment takes place in a home or medical setting.
UVA rays are shorter than UVB and penetrate your skin more deeply. Because UVA rays are not as effective in clearing the signs of psoriasis, a medication called psoralen is added to the light therapy to increase effectiveness.Some doctors prefer treating psoriasis using UVA instead of UVB rays. They are shorter by penetrating the skin deeper. They combine UVA treatment with psoralen, a medication that involves taking drugs orally before or apply topical prescription on the surface to allow absorption of more light. Vitamin D from the sun helps in reducing inflammation in the body.
The sun in addition to healing helps to fight infection by increasing white blood cells that the body uses to fight diseases. It also kills bad bacteria as a natural disinfectant.
