How Your Morning and Nighttime Routines Affect Your Health

What you do: Gauge your hunger before having a bedtime snack

Why it's good: You're listening to your body instead of mindlessly munching, a key to maintaining healthy weight, Politi says.

One more thing: If you can't get your mind off the cookies in the cupboard, Politi suggests thinking about a food you don't strongly like or dislike to figure out if your hunger is physiological or emotional. (Maybe a type of fruit that you neither love nor hate.) "If you'd eat the cookies but not the other food, your hunger is emotional and you should just go to bed," she says. "But if you would eat the other food, then you're actually hungry and should eat the food you're craving so you feel satisfied and your hunger doesn't affect your sleep."
