There’s nothing like a good night’s sleep – but what does that really mean?
It turns out the answer depends not only on your age, but also on your lifestyle. And at the end of the day it comes down to this: Are you healthy, clearheaded and productive? Some people are productive and happy with fewer hours of sleep, while others need more.
To create the recommendations, a panel of sleep and medical experts reviewed 312 articles from journals published during the last decade.
Health factors, including obesity or caffeine use, can impact whether a person sleeps well. A lack of sleep also can be linked to weight gain, because sleep deprivation causes an increase in appetite, according to the foundation.
It can also have negative consequences on the brain. People who do not get enough sleep are at increased risk for depression and substance abuse, and can endanger others. Those that become sleepy while driving, for example, risk both their lives and the lives of those around them.
Researchers also have found in the past that too much sleep can have negative effects. Low socioeconomic status and depression reportedly are significantly associated with longer sleep.
However, research on oversleeping is still found to be inconclusive and needs more attention, as peer-reviewed studies have appeared to disagree on how or even whether to approach patients who sleep too much.
“Currently, there is no strong evidence that sleeping too much has detrimental health consequences, or even evidence that our bodies will allow us to sleep much beyond what is required,” Kristen Knutson, an assistant professor at the University of Chicago, said in a statement. “There is laboratory evidence that short sleep durations of four to five hours have negative physiological and neurobehavioral consequences. We need similar laboratory and intervention studies to determine whether long sleep durations (if they can be obtained) result in physiological changes that could lead to disease before we make any recommendations against sleep extension.”
Other research has shown that a group of people who slept seven hours had a lower mortality rate after six years than those who slept both more and less.
