Light is the major synchronizer of circadian rhythms to the 24-hour solar day. Compared to the visual system, the circadian system requires more light to be activated and is more sensitive to short-wavelength light. Without access to daylight, or electric lighting providing comparable amount, spectrum, distribution, duration, and timing, human...

The human biological clock, also known as circadian rhythm, is mainly synchronized by the light perceived, specifically short-wavelength. Insufficient access to daylight or equivalent electric lighting can compromise human health and well-being. The effect of light on the circadian rhythm is greater in children and adolescents than in adults,...
