There are several wavelengths of energy from sunshine that trigger specific actions within the body to influence our health; different wavelengths are able to penetrate the skin to different depths and have certain effects on the cells and tissues they reach
UVB radiation stimulates the production of vitamin D, as well as serotonin and beta-endorphins, UVA promotes the release of nitric oxide into the blood, and both have a positive effect on the diversity of the microbiome on the skin and in the gut
Blue light has a strong regulatory effect on the circadian rhythm and the release of melatonin from the pineal gland, while red light, near-infrared radiation, and far-infrared radiation have anti-inflammatory and tissue healing effects; infrared radiation also stimulates the production of melatonin inside the mitochondria for a strong antioxidant effect

The energy given off from the sun (aka the solar spectrum) consists of different wavelengths between 300 nm and well over 1 mm.

340,000 deaths per year in the United States and 480,000 deaths per year in Europe, as well as a rise in many diseases, could be attributed to insufficient sun exposure or “sunshine deficiency.”
