Halt your afternoon habit

It’s a no-brainer that drinking coffee or tea right before you hit the sack won’t do you any sleep favors. But you also need to watch your afternoon drinks, says Joan Salge Blake, RD, a clinical associate professor at Boston University. Love your 4 p.m. peach tea? It’s got caffeine, and so do some flavored waters and even orange sodas, Blake warns. Check the labels on your favorite midday drinks—any that boast energy-boosting benefits are likely culprits. Then, if possible, stop sipping them by 2 p.m., so there’s time for their effects to wear off. Naturally, coffee drinks pack a real wallop, so stay away from them after lunch.
