Dim Lights After Sunset

In the evening and overnight, use the lowest light level you can safely function with: dim indoor lights, avoid bright screens and overhead lighting, and keep the bedroom as dark as possible. If you wake up at night, use only the minimum light needed and turn it off quickly; red or very dim low-positioned lighting is preferred when light is unavoidable. This helps preserve melatonin, reduce circadian disruption, and make it easier to fall and stay asleep.
