Temperature can change your mattress
“Memory foam is very temperature dependent. The foam can get a little hard in a cold bedroom. And if you’re a hot sleeper, it may make you hotter.” —Alan Hedge, PhD, professor of ergonomics at Cornell University, Ithaca, New York. Try these tricks for better sleep from sleep doctors.
Familiar smells help you sleep
“My research has found that any new smell, even one associated with relaxation, like lavender, can make you more alert and vigilant. You’re better off with a scent that makes you feel safe and comfortable. There really is something to cuddling up with your spouse’s undershirt.” —Pamela Dalton, PhD, odor-perception expert and sensory psychologist at Monell Chemical Senses Center, Philadelphia, Pennsylvania
