How many hours of sleep did you log last night? Harvard scientists found that people who slept for five hours or less a night were 32 percent more likely to put on 33 extra pounds over the course of a year than those who slept a full seven hours. So sleep is important for feeling rested and maintaining a healthy weight, and what you eat before you go to bed can affect the quality of your sleep. Some foods can sabotage your slumber, causing you to wake frequently throughout the night (or even making it difficult to fall asleep in the first place). However, other foods can actually increase the hormones in your brain that promote relaxation and high quality sleep. Read on for smart diet swaps -- and finally claim that full night of rest.
