Getting enough deep sleep helps the brain clear out waste products that could lead to Alzheimer’s disease. New animal research reveals that one particular sleeping position may also help flush harmful substances out of the brain.
Lying on the side is the most common sleep position for humans. Interestingly, it’s also the most common sleep position for animals in the wild. Fascinating new research from Stony Brook University may explain why: A side-sleeping position seems to improve waste clearance from the brain, which could prevent Alzheimer’s disease and neurodegenerative diseases.
