1. Lower risk for Multiple Sclerosis

New research into MS offers insight into the link between sunlight, vitamin D3, and MS risk and severity. The research, published in the European Journal of Immunology, studies the relationship between the sunlight-dependent vitamin D3 hormone and the risk of autoimmunity in an experimental model. The researchers found that higher levels of sun exposure were significantly associated with lower levels of depression and fatigue.  This association disappeared after adjusting for the influence of sunlight.
These observations suggest environmental exposure in the first two decades of life, influences the risk of developing MS.

2. Helps heal psoriasis

Psoriasis is a nightmare to treat for all those that have it quite severe. Many over the counter creams and ointments do not help. Most people who have psoriasis find that the sun or being in daylight helps to improve their skin’s appearance. Exposure to sunlight is extremely beneficial for individuals with psoriasis. In one study, an outdoor four-week sunbathing therapy was shown to promote significant clearance of psoriatic symptoms in 84 percent of subjects.

3. Ease mild depression

There has been a lot of research on the link between sunlight and mood. There has been a lot of research into the findings that sunlight actually increases levels of a natural antidepressant in the brain. On sunny days, the brain produces more of the mood-lifting chemical serotonin than on darker days.

4. Improve sleep quality

When sunlight hits your eyes, your optic nerve sends a message to the gland in the brain that produces melatonin (a hormone that helps you sleep); the gland decreases its secretions of melatonin until the sun goes down again. In other words, exposure to sunlight during the day increases the natural production of melatonin at night. Low levels of melatonin production are linked to poor sleep quality, especially in older adults.
