Sleeping on your back may increase your brain’s risk of developing neurodegenerative disease. This possibility is revealed in a new study published in the Journal of Alzheimer’s Disease.
Sleeping more than two hours with one’s head lying face upward (i.e., in supine position) was a significant nocturnal marker that characterized those with memory impairment, after controlling for factors such as age, sex, snoring, obstructive sleep apnea, and movements during the night.

But it’s important to know that imaging of the glymphatic system in humans is not yet possible. Therefore, additional research is needed to establish a causal relationship between neurodegenerative disease and supine sleep.
