Get a good night's sleep to improve your memory, metabolism and overall health.

One night of insufficient or interrupted sleep can ruin your day. It is harder to wake up the next morning, you feel sluggish and foggy all day, and your motor skills are not their sharpest. But chronic sleep deprivation, depending on its severity and duration, can interfere with your long-term memory, and is associated with greater risk of depression symptoms and weight gain. While we are sleeping, important upkeep tasks are going on throughout the body. Feeling chipper and rested is only part of sleep's payoff.
