We discuss the full solar spectrum and how ultraviolet, visible, blue, red and near-infrared light each affect human physiology, including the POMC pathway, nitric oxide and blood pressure, and the evidence on sunlight, skin cancer and the vitamin D paradox.
We discuss how artificial light at night suppresses melatonin and disrupts the circadian control of DNA repair, cardiovascular health, and metabolism.
For those interested in light and circadian health, Dr. Gulhane offers a grounded, mechanism-focused framework for aligning daily light exposure with human biology.
