A groundbreaking study in The Journal of Neuroscience reveals that sleeping on your side optimizes the brain's natural waste clearance process, potentially lowering the risk of Alzheimer's and other neurodegenerative diseases that impair brain and nervous system function.
Encouragingly, side sleeping is the most common position among humans—and even wild animals.
Researchers tested this on rodents, finding side sleepers eliminated brain waste far more effectively than those in other positions.
So, what exactly is brain waste? It's a buildup of metabolic toxins that can interfere with neural processes if not removed. During sleep, a specialized fluid flushes through the brain to clear these toxins—making an optimal position crucial for this vital detox.
While not yet conclusively proven in humans, this discovery could transform strategies for preventing dementia and related conditions.
And you—which side do you prefer?
