Poor sleeping may shrink brain
Lack of sleep may actually change the size of your brain. According to a new study published in the journal Neurology, researchers found that for every hour of reduced sleep, older adults may experience an incremental expansion of the brain ventricles and a decline in cognitive performance.
For the study, scientists at the University of Oxford in the U.K. analyzed sleep patterns of 147 participants between the ages of 20 to 84 every three and a half years. They assessed how long the participants slept, how long it took to fall asleep at night and their sleeping medication use.
The results showed that participants who had sleep difficulties during the study period showed a decline in brain volume, especially adults over the age of 60. The researchers said that they'd next like to investigate whether an improvement in sleep could help slow brain shrinkage.
