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 are getting less than the recommended seven or eight hours of sleep, you might be causing harm to yourself. Here are 8 reasons why you need to sleep well.
Having a good night’s sleep could improve your health.
Study has found a link between insufficient sleep and some serious health problems, such as heart disease, heart attacks, diabetes, and obesity. 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.
Studies have shown that while we sleep, our brains process and consolidate our memories from the day. If you don’t get enough sleep, it seems like those memories might not get stored correctly — and can be lost.
Research suggests that sleep decreases the chances of developing false memories. In several experiments, people were asked to look over a series of words. Later they were tested on what they remembered. People who didn’t sleep in between were much more likely to “remember” a word that they hadn’t actually seen before.
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. 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.
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.
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.
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.
Have you ever woken up after a bad night’s sleep, feeling fuzzy and easily confused, like your brain can’t get out of first gear?
“Sleep loss affects how you think,” Mindell tells WebMD. “It impairs your cognition, your attention, and your decision-making.” Studies have found that people who are sleep-deprived are substantially worse at solving logic or math problems than when they’re well-rested. “They’re also more likely to make odd mistakes, like leaving their keys in the fridge by accident,” she tells WebMD.
Could getting enough sleep prevent the common cold? One preliminary study put the idea to the test. Researchers tracked over 150 people and monitored their sleep habits for two weeks. Then they exposed them to a cold virus.
People who got seven hours of sleep a night or less were almost three times as likely to get sick as the people who got at least eight hours of sleep a night. More research is needed to establish a real link; this study was small and other factors may have influenced the results. Still, you can’t go wrong getting eight hours of sleep when possible.
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.”
