  • SURPRISING HEALTH BENEFITS OF SLEEP

In other words if you’re trying to learn something new—whether it’s Spanish or a new tennis swing—you’ll perform better after sleeping.

Live longer
Too much or too little sleep is associated with a shorter lifespan—although it’s not clear if it’s a cause or effect. (Illnesses may affect sleep patterns too.)
In a 2010 study of women ages 50 to 79, more deaths occurred in women who got less than five hours or more than six and a half hours of sleep per night. Sleep also affects quality of life.

"Many things that we take for granted are affected by sleep," says Raymonde Jean, MD, director of sleep medicine and associate director of critical care at St. Luke’s-Roosevelt Hospital Center in New York City. "If you sleep better, you can certainly live better. It’s pretty clear."

Curb inflammation
Inflammation is linked to heart disease, stroke, diabetes, arthritis, and premature aging. Research indicates that people who get less sleep—six or fewer hours a night—have higher blood levels of inflammatory proteins than those who get more.

A 2010 study found that C-reactive protein, which is associated with heart attack risk, was higher in people who got six or fewer hours of sleep a night.
People who have sleep apnea or insomnia can have an improvement in blood pressure and inflammation with treatment of the sleep disorders, Dr. Rapoport says.

Spur creativity

Get a good night’s sleep before getting out the easel and paintbrushes or the pen and paper. 

In addition to consolidating memories, or making them stronger, your brain appears to reorganize and restructure them, which may result in more creativity as well.
Researchers at Harvard University and Boston College found that people seem to strengthen the emotional components of a memory during sleep, which may help spur the creative process.

Be a winner
If you’re an athlete, there may be one simple way to improve your performance: sleep.
A Stanford University study found that college football players who tried to sleep at least 10 hours a night for seven to eight weeks improved their average sprint time and had less daytime fatigue and more stamina. The results of this study reflect previous findings seen in tennis players and swimmers.
Have a healthy weight

If you are thinking about going on a diet, you might want to plan an earlier bedtime too.
Researchers at the University of Chicago found that dieters who were well rested lost more fat—56% of their weight loss—than those who were sleep deprived, who lost more muscle mass. (They shed similar amounts of total weight regardless of sleep.)

Dieters in the study also felt more hungry when they got less sleep. "Sleep and metabolism are controlled by the same sectors of the brain," Dr. Rapoport says. "When you are sleepy, certain hormones go up in your blood, and those same hormones drive appetite."
