Turn On Lights in Teen's Room Before Wake Time
Turn on the lights in a teen’s room before they wake up to help them fall asleep earlier the next night and get about 45 minutes more deep sleep and more total sleep. Some parents also use a flashlight through closed eyelids before wake time to mimic this effect, though this was not part of the standard study.
