Dr. Holliday-Bell swears by a few must-have sleep accessories: a fan, red light, andblackout sleep mask.

She also switches on a red light, which somesmall studieshave found might promote natural melatonin release.

They can help improve the ability to fall and stay asleep, due in part to that emotional association.

Then do it again tomorrow.

Doing the proper things even in one night can make a big difference, she says.
