Answer: It helps to regulate circadian rhythm
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
cycle. Circadian rhythm plays an
important role in
controlling when we fall asleep and when we wake up.
During day light, the secretion of melatonin or sleep hormone is
suppress by melanopsin that keeps people awake and alert. Nevertheless, during nighttime,
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.
