9 Surprising Reasons to Get More Sleep
What difference could an extra hour of sleep make in your life? Maybe quite a lot, experts say. Studies show that the gap between getting just enough sleep and getting too little sleep may affect your health, your mood, your weight, and even your sex life.
If you're getting less than the recommended seven or eight hours of sleep a night, here are nine reasons that you should shut down your computer, turn off the lights, and go to bed an hour early tonight.
1. Better health. Getting a good night's sleep won't grant you immunity from disease. But study after study has found a link between insufficient sleep and some serious health problems, such as heart disease, heart attacks, diabetes, and obesity.
In most cases, the health risks from sleep loss only become serious after years. That might not always be true, however. One study simulated the effects of the disturbed sleep patterns of shift workers on 10 young healthy adults. After a mere four days, three of them had blood glucose levels that qualified as pre-diabetic.
2. Better sex life. According to a poll conducted by the National Sleep Foundation, up to 26% of people say that their sex lives tend to suffer because they're just too tired. There's evidence that in men, impaired sleep can be associated with lower testosterone levels -- although the exact nature of the link isn't clear.
Of course, not getting enough sleep can affect your love life in less direct ways too. "If you're a 28-year-old who's so exhausted you're falling asleep during a date at the movies, that's not good," says Ronald Kramer, MD, a spokesperson for the American Academy of Sleep Medicine and a specialist at the Colorado Sleep Disorders Center in Englewood, Colo.
3. Less pain. If you have chronic pain -- or acute pain from a recent injury -- getting enough sleep may actually make you hurt less. Many studies have shown a link between sleep loss and lower pain threshold. Unfortunately, being in pain can make it hard to sleep.
Researchers have found that getting good sleep can supplement medication for pain. If pain is keeping you up at night, there are also medications available that combine a pain reliever with a sleep aid.
