Exposure to sunlight boosts serotonin levels. It is believed that the brain when exposed to sunlight, excretes serotonin. Serotonin is a hormone responsible for improving mood, calmness and mental clarity.

Lack of sun exposure and vitamin D deficiency have been linked to many
serious chronic diseases:

  • Autoimmune diseases
  • Infectious diseases
  • Cardiovascular disease
  • Deadly cancers

It is estimated that there is a 30 to 50% reduction in risk for developing colorectal, breast, and prostate cancer by either increasing vitamin D intake to least 1000 IU/d vitamin D or increasing sun exposure to raise blood levels.
