Improving the Quality of Life with Light

Exposure to full-spectrum sunlight which was common in our ancestral environment, is something we need to obtain or mimic if we want optimal health. Unfortunately, artificial light sources don’t reproduce all of the many facets of sunshine in indoor environments.

Based on current research, some of the essential missing facets are UV-A light for nitric oxide, UV-B light for vitamin D, red light for nighttime circadian rhythm entrainment, and red and near infrared light in the daytime for mitochondrial respiration (ATP regeneration).
