Dim Light Evening
Reducing bright and blue-rich light before bed to support melatonin timing—lamps, screen dimming, and night modes as practical tools.
Dim light evening is lowering indoor brightness and blue-rich screens one to three hours before bed so melatonin onset faces less delay. Warm lamps, lowered backlight, and night modes help; complete darkness prep is not required.
Pair with fixed wake time and morning outdoor light for circadian stability.
Common questions
-
Do blue-light glasses replace dimming rooms?
Glasses may help but lowering overall room brightness and screen intensity is the foundation. Behavioral wind-down still matters.
