- UV energy triggers skin-protective responses against stress, coordinated by the cutaneous-neuroendocrine system, and activates central neuroendocrine system pathways that regulate global homeostasis. The sensory and computing capabilities of the skin are designed to control cutaneous and body homeostasis (1).

Vitamin D is also critical for your immune system, and with consistent exposure to sunlight, you can help strengthen it. A healthy immune system can help reduce the risk of illness, infections, some cancers, and mortality after surgery.
It’s not just in your head; there’s a scientific reason being in the sunshine improves your mood. Sunshine boosts your body’s level of serotonin, which is a chemical that improves your mood and helps you stay calm and focused.

A studythat followed 30,000 Swedish women revealed that those who spent more time in the sun lived six months to two years longer than those with less sun exposure. More research needs to be done in this area, but it’s something scientists are continuing to study. Related: 5 Effective Ways to Soothe Sunburns At Home Of course, a little sunshine can...
This burden subsumes major disorders of the musculoskeletal system and possibly an increased risk of various autoimmune diseases and life-threatening cancers. The best-known benefit of sunlight is its ability to boost the body’s vitamin D supply; most cases of vitamin D deficiency are due to lack of outdoor sun exposure.

Research in recent years has provided increasing evidence that exposure to environmental UV levels can alter the activity and distribution of some of the cells responsible for triggering immune responses in humans. As a consequence sun exposure may enhance risk of infection or reduce the body's defences against skin cancer.
