Try A Sleep Mask
A device that never runs out of batteries! Dr. Benjamin Smarr, National Institutes of Health Postdoctoral Fellow at UC Berkeley and Reverie sleep advisory board member recommends people get a comfy sleep mask to cut down on light-at-night that interrupts good sleep. Dr. Smarr said, “Even better, putting on your mask can become part of the pre-sleep ritual. Such rituals can be important psychological sleep aids for people with difficulty getting to sleep at night.”
