You’ve probably heard that you need to get your eight hours of sleep
a night, but how often do you actually get that? Most people get by on
six or seven hours, or sometimes even less. And sometimes this feels
fine. But this might be even more harmful than we thought.
Sleep deprivation
can be really serious—even as serious as some diseases, like cancer.
That’s because frequently not getting a full night’s rest is linked to a
higher risk of actually getting cancer, according to a study
published in the Journal of the National Cancer Institute. Research has
shown lack of sleep can lead to colon or breast cancer in particular.
Being sleep impaired can also have a negative effect on your heart, a study
published in Sleep Medicine Reviews found. Blood pressure and risk of
heart disease can both increase the more sleep deprived you are.
There’s
more bad news. If you ever noticed that on a day you were particularly
sleep deprived, you can’t remember much that happened that day, there’s
research to back that up. One study
published in the Journal of Clinical Endocrinology and Metabolism
(among others) have found that adults running on empty have find it
difficult to remember words they’ve learned and are sometimes unable to
improve skills that were learned on that day.
