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.
4. Lower risk of injury. Sleeping enough might actually keep you safer. Sleep deprivation has been linked with many notorious disasters, like the destruction of the space shuttle Challenger and the grounding of the Exxon Valdez. The Institute of Medicine estimates that one out of five auto accidents in the U.S. results from drowsy driving — that’s about 1 million crashes a year.
Of course, any kind of accident is more likely when you’re exhausted, says Jodi A. Mindell, PhD, a professor of psychology at St. Joseph’s University in Philadelphia and author of Sleep Deprived No More. “When you’re overtired, you’re more likely to trip, or fall off a ladder, or cut yourself while chopping vegetables,” she says. “Household accidents like that can have serious consequences.”

5. Better mood. Getting enough sleep won’t guarantee a sunny disposition. But you have probably noticed that when you’re exhausted, you’re more likely to be cranky. That’s not all. “Not getting enough sleep affects your emotional regulation,” says Mindell. “When you’re overtired, you’re more likely to snap at your boss, or burst into tears, or start laughing uncontrollably.”
6. Better weight control. Getting enough sleep could help you maintain your weight — and conversely, sleep loss goes along with an increased risk of weight gain. Why? Part of the problem is behavioral. If you’re overtired, you might be less likely to have the energy to go for that jog or cook a healthy dinner after work.
The other part is physiological. The hormone leptin plays a key role in making you feel full. When you don’t get enough sleep, leptin levels drop. Result: people who are tired are just plain hungrier — and they seem to crave high-fat and high-calorie foods specifically.
7. Choose pillow and mattress for sleeping position: We recommend choosing a pillow and mattress fit your sleeping position. For example, if you are sleeping, you can use the Coop Home Goods Pillow or Buckwheat Pillow . This will help you both a lot of good sleep.
