Exposure to natural light during the day helps regulate the circadian
rhythm, which improves sleep pattern. The term circadian rhythm refers to our
biochemical, physiological and behavioral processes in approximately 1 full day

melanopsin stimulates the release of melatonin to signal sleeping time. Therefore,
this hormone works the entire day and has direct effect on the circadian
rhythm, which acts as a regulator of our biological clock.
