Sunlight health effects

The sunlight is essential to life. Sunlight is a made of wide spectrum of frequencies that include: infrared rays, visible light, and ultraviolet rays. At lower frequencies, sunlight changes to a gentle “Infra-red rays”, which gives sunlight its “Warm” sensation

The room light bulb (50-200 lumination index – Lux for 100 W) will produce visible light, with various wavelengths missing when comparing to the visible light from the sun (25.000-125.000 lumination index – Lux). An incandescent bulb typically discharges visible light in the red, green, blue, and violet waveforms. The sun, on the other hand, will emit these along with various others, including yellow, purple, turquoise, and so on. For this reason, visible light from the sun allows us to see more colors with better crispness

People working under white fluorescent tube lighting for a period of time produced significantly higher levels of stress hormones such as adrenocorticortropic hormone and cortisol, while a full-spectrum or natural light lowered levels of these hormones, and lowered stress among the humans

According to Raymond Peat, sun light is essential for mitochondrial health. The enzyme “Cytochrome c oxidase”, the enzyme that couples hydrogen with oxygen to produce water in the electron transport chain, absorb red light coming from the sun, which energizes the enzyme by removing the accumulated nitric oxide released by the mitochondria during biochemical reactions. Staying in the dark for more than 2 hours can inhibits the mitochondria due to the accumulation of nitric oxide within the mitochondria
