... if you've reached middle age, at least. A new study from the University College London Medical School found that those who usually get six to eight hours of sleep per night score lower on almost every test measuring cognitive function if they get less sleep once hitting middle age.
Of course, the human brain naturally loses some of its cognitive ability as it ages, but this study found that a change in sleep patterns can speed up cognitive decline.
Perhaps even more interesting, the study found that cognitive decline was even worse in those who started to get more sleep - those who slept more than eight hours after hitting middle age fared the worst in the cognitive function tests.
For the purposes of this study, you're considered to have reached middle age after your 45th birthday. The study included both men and women.
So what can we take away from this study? Well, we're reminded of just how important sleep is. We are also seeing a suggestion that sleep quality is far more important than sleep duration.
