BOSTON (CBS) — Poor sleep is bad for the brain. Now, experts think that sleep position may be important, too.

Most humans and animals sleep on their sides and as it turns out, that may be the best sleep position to help prevent brain disorders like Alzheimer’s Disease or Parkinson’s Disease.

Researchers found that when rodents slept on their sides they were more effective at filtering out waste products from the fluid surrounding the brain and spinal cord, damaging proteins that could contribute to brain diseases.
