Fact of the day: Most efficient sleep position to clear the brain of waste

Your sleep position at night matters a lot. Not head-up, nor head-down, but sleeping on your side is the most efficient position to clear waste materials from the brain.

This is because the glymphatic system (exchange of CSF with the interstitial fluid to get rid of damaging brain proteins) of our brain works most efficiently in lateral position compared to supine or prone position.

Lateral position and right posture while sleeping is considered advantageous for those suffering from neurologic and psychiatric disorders due to this reason.

That's all
