1. Improve your brain power.

Just because you’re asleep doesn’t mean your brain isn’t busy behind the scenes. Have you ever felt panicked the night before an exam because you couldn’t recall any of the material you were cramming in, but then the next morning you woke up to discover a staggering difference in your ability to remember? If so, this happened because your brain strengthens your memories while you sleep. Whether you’re learning a new language, studying for a test, or exploring a new hobby, expect to perform better after a good night’s sleep.

 

2. Enjoy more (and better) sex.

A study by the National Sleep Foundation discovered an alarming trend among Americans: one out of every four adults married to or living with a partner say they are often “so sleep-deprived that they are too tired to have sex.” The excuse “too tired to have sex” shouldn’t even exist, so please improve your sleep (for the sake of your sex life!).

 

3. Lose weight while you sleep.

Several studies point in the direction of a connection between a poor night’s sleep and weight gain. A recent study by the American Heart Association found that the sleep-deprived participants ate an average of 549 additional calories more than the control group (who slept an additional hour and twenty minutes).

 

4. Increased safety on the road.

A lack of sleep could lead to danger. According to a study by the American Automobile Association, 1 out of 6 deadly traffic accidents are due to drowsy driving. If you can help it, please don’t get behind the wheel when you’re so sleepy you can barely hold your head up. The signs of drowsy driving include drifting into another lane, frequent blinking, and lapses of concentration (i.e. when you realize you’re 10-20 miles farther and you didn’t even notice the journey).
