Mom Was Right: A Good Night's Sleep Helps Keep You Healthy. Too little shuteye is linked to higher risk of colds and infections.
In news that's sure to have mothers everywhere saying, "I told you so," scientists have confirmed that a good night's sleep may keep colds and other infections at bay. The odds that someone who sleeps five or fewer hours a night had caught a cold in the past month were 28 percent higher than for folks who regularly get more shuteye, the study found. And for other infections -- including flu, ear infections and pneumonia -- short sleepers had more than 80 percent higher odds of having an infection in the past month compared to those sleeping seven or eight hours, the study said.
"People who sleep five or fewer hours on average are at substantially increased risk for both colds whether head or chest or other infections, compared to people who sleep seven to eight hours on average," said study researcher Aric Prather. He's an assistant professor of psychology at the University of California, San Francisco.
The researchers also found that people who have sleep disorders or those who have ever told their physician that they have sleep troubles had about 30 percent higher odds of having had a cold in the previous month. The odds of infection in the past month for people with sleep disorders were more than doubled, the study said.
Experts cannot say for sure why lack of sleep helps increase susceptibility to infections. However, Prather said, it is known that T-cells, a type of white blood cells that fight off infection, don't work as well when you are sleep-deprived. People can become better sleepers, Prather said. Getting up at the same time every day is a start, he said. "Make sure your bedroom is cool, quiet and dark," he advised. "Have a wind-down period [before going to sleep]."
