Mental Illness and Light – Part 2.5 of a 7 Part Series

Welcome back to our Physiological Need for Light series! Today, we ponder on links between mental illness and light.


  • Mental illness has increased as humans have migrated out of the sun.

  • Low 25 [OH]D levels with mental illness and learning disorders.

  • Depression has significant co-morbidity with illnesses associated with Hypovitaminosis D.

  • Humans get little to no Vitamin D from the sun when the UV index is 3 or below.

  • Nuclear receptors for Vitamin D in the brain.

  • Rats born to severely low Vitamin D levels have profound brain abnormalities.

  • Dark skinned individuals cannot produce as much Vitamin D from sunlight in the same time frame as fair skinned individuals.
