If you’re having trouble falling asleep or keeping your eyes shut at night, what you had to drink might be to blame.

The obvious one is caffeine, says Jessica Garay Redmond from the Department of Nutrition and Food Studies at Syracuse University, who notes a person should cut off those beverages, “at some point in the afternoon or certainly by dinner time so that they can then have a restful night sleep.”

Another no-no is alcohol, which “traps you in the lighter stages of sleep and dramatically reduces the quality of your rest at night,” reveals Rebecca Robins, a researcher at NYU Langone Health. Robins instead suggests drinking milk before hitting the pillow.
