Why is bright light at night bad for sleep?
Sources:
Bright light exposure at night is detrimental to sleep because it suppresses the natural release of melatonin, the hormone which promotes sleepiness and allows you to fall asleep 1. Bright light, particularly overhead artificial light, during the period from 10:00 p.m. to 4:00 a.m., can reset and shift your circadian clock, negatively impacting sleep quality 2. Light reception by melanopsin cells in the retina even through closed eyelids, commonly in children or individuals with thin eyelids, can lead to disruptions in sleep patterns and an increased risk of myopia, or nearsightedness 3.
It's recommended to avoid as much light as possible during these nighttime hours and instead, get bright light, preferably sunlight, in the early part of the day to properly set your circadian rhythm 1 4. Proper light exposure supports overall mood, learning, focus, metabolism, and can enhance sleep quality 5.
