The Sleep Pattern Linked To Being Smarter

Half the people in the study,
though, slept about an hour less than the recommended amount.
Sleeping between 7 and 8 hours
a night is best for the brain, new research concludes.
More or less sleep than this
is linked to lower cognitive performance.
Half the people in the study,
though, slept about an hour less than the recommended amount.
The brains of people who slept
four hours or less were nine years older, cognitively.
Over-sleeping was also linked
to worse cognitive performance.
Professor
Adrian Owen, the study’s first author, said:
“We really wanted to capture
the sleeping habits of people around the entire globe. Obviously, there have
been many smaller sleep studies of people in laboratories but we wanted to find
out what sleep is like in the real world. People who logged in gave us a lot of
information about themselves. We had a fairly extensive questionnaire and they
told us things like which medications they were on, how old they were, where
they were in the world and what kind of education they’d received because these
are all factors that might have contributed to some of the results.”
The results come from over
40,000 people around the world who completed a survey and cognitive tests.
Lack of sleep — or too much —
was bad for the brains of young and old just the same.
Dr
Conor Wild, study co-author, said:
“We found that the optimum
amount of sleep to keep your brain performing its best is 7 to 8 hours every
night and that corresponds to what the doctors will tell you need to keep your
body in tip-top shape, as well.
We also found that people that
slept more than that amount were equally impaired as those who slept too
little.”
The study was published in the
journal Sleep (Wild et al., 2018).
