Side‑sleeping—especially on your side—is currently considered the best position for brain waste clearance, based on animal research and preliminary human observations.

[left-side sleeping may be better for digestion and could reduce acid reflux symptoms. On the other hand, right-side sleeping might be more comfortable for those with heart conditions or sleep apnea]

Sleeping on your back (supine) may be associated with slower glymphatic clearance and higher Alzheimer’s-related risk markers, according to observational data

Although hypotheses linking sleep position to Alzheimer’s risk remain tentative, current evidence suggests side‑sleeping supports better glymphatic clearance, while back‑sleeping is observed more frequently in people with Alzheimer’s-like conditions. There’s no definitive proof yet, but it’s an intriguing area of early research.
