Sleeping nine hours a night can be just as bad for your memory as turning five

Sleeping for nine hours a night can be just as bad for your memory as only five, new study reveals

  • Researchers looked at the results of the memory test for nearly 400,000 people
  • They were asked to match pairs of hidden cards after they had memorized their positions
  • Those who slept for nine hours made as many mistakes as those who slept five

Sleeping nine hours a night can be just as bad for your memory as turning five.

It is known that people who sleep less than five hours a night can expect memory problems. But one study found the same effects for those who sound healthy for nine hours a night.

Researchers looked at the results of the memory test for nearly 400,000 people who were asked to match six pairs of hidden cards after they remembered their positions.

Compared to people who got seven hours of sleep, those who had slept for nine hours made the same number of mistakes as people who slept five or fewer.

They made 5 percent more mistakes in the card game, which fell to two percent when factors such as age and gender were taken into account.

And those who slept for ten hours made 11 percent more mistakes – six percent when they were adapted to people's characteristics.

The results suggest that sleeping too long can affect thinking skills, as well as lack of sleep.

Researchers also looked at the genetics of the participants and thus took into account those who had the aptitude to sleep longer. This excluded health problems that had an impact on their results.

Dr. Victoria Garfield, senior author of the UCL study, said the & # 39; not so novel & # 39; is to discover that less sleep is bad for you, but called this result & # 39; unusual & # 39 ;.

She added: & # 39; Some people may think that going to bed and sleeping as long as you want is fine, but our findings show that sleeping too long can have an impact on memory. & # 39;

Albert Henry, lead author of the study published in the International Journal of Epidemiology, said: & # 39; We have found little evidence that short or long sleep is linked to the risk of dementia, but more research is needed. & # 39;
