Block light leaks that keep your brain half-awake
Even a thin stripe of streetlight or a charging LED can keep your brain half-awake. Block light leaks with curtains that actually close, a simple blackout panel, an eye mask, or tape over stubborn indicator lights. Cover the glowing clock if it bothers you. Darker rooms make it easier to stay asleep when you roll over at 2 a.m. You do not need a renovation—test one window first. Morning light can still wake you if you open the curtain on purpose. Nighttime darkness is the free signal that says rest, not another notification.
