Abstract

The effect of night light on the body can have negativeconsequences in the form of disruptions of the circadian rhythm of melatoninsynthesis. Night light will be perceived by the retina (blue light of 446–477 nmwavelength was found to be the strongest input for melatonin regulation in healthysubjects), will be transmitted to the hypothalamic nuclei and then the inhibitory signalwill go to the pineal gland and the synthesis of the hormone will be suppressed. Inturn, melatonin deficiency can lead to mood disorders - anxiety, depression, inaddition, cancer diseases may occur or progress.
