Q: What improves when you get more sleep? A: Everything. When you get more sleep, your body has more energy, making it more primed to exercise and burn calories through activity. "Sleep recharges and resets your body," Smith says. "When you don't get the rest you need, your body is always 'on,' trying to help you recover. You can mask it with caffeine for awhile, but eventually, you'll crash."
Overcome it: Let go of those late-night habits (record Jimmy Fallon if you have to), and stay away from caffeine-packed energy drinks, especially after 3 p.m. You'll recover faster from workouts. You'll also have more power to overcome cravings. And you'll feel more alert, making you more likely to make better decisions throughout the day. Check out these secrets for muscle-building sleep.
