The Importance of Light in Human Health

Light plays a crucial role in human health, often viewed as a nutrient necessary for well-being. Infrared and UV light are especially vital, with the indoor environment typically lacking these essential spectrums. Exposure to natural light, especially in the morning, fuels circadian rhythms, promoting hormones like cortisol that dictate daily energy levels and signaling. Regular exposure to full-spectrum sunlight, as opposed to artificial sources, can drastically improve overall health and daily functioning.
