Most of us do things at night that are counter-productive to actually sleeping. Instead, make slight changes in your rituals to prepare your body for rest.
Dim your lights several hours before bed to avoid the stimulation caused by artificial light pollution—which is all around us through TV, computers, and indoor lighting—and serves to stimulate us.
Come up with a regular, rhythmic evening ritual that allows you to embrace anxieties that get released when you slow down. Meditation, prayer, and deep breathing are all good methods.
Surrender to sleep. After all, you go to the movies, you shouldn't go to sleep. There is nothing you have to do to sleep—except let go of waking. Practice "dying" into sleep—rather than forcing yourself to sleep—and cultivate awareness of your personal twilight zone.
