IF you want to enhance your brain health, try sleeping on your side.
When we sleep, our brain clears out waste products generated from a day of activity - and it does this more effectively if you sleep on your side. At least, this is the case in animals, according to neuroscientists at Stony Brook University in the United States, who think this probably translates to humans, too.
Their study, published in the Journal of Neuroscience in 2015, was based on MRI scans.
"The lateral sleep position is already the most popular in humans - and most animals.
"It appears that we have adapted the lateral sleep position to most efficiently clear our brain of the metabolic waste products that build up while we’re awake," says Dr Maiken Nedergaard, who led the study.
Many conditions, including Alzheimer’s disease, are linked to a build-up of proteins and other cellular waste in the brain, so the more you clear, the better.
