The Shocking Link Between Sleep Position and Alzheimer's Risk
Recent Yale Medicine research reveals a startling connection between sleep position and Alzheimer's risk. Side sleeping enhances glymphatic clearance by up to 25% compared to back sleeping, significantly improving your brain's ability to remove beta-amyloid proteins associated with Alzheimer's disease. Studies show just two hours of supine (back) sleeping reduces this critical brain-cleaning process, while left-side sleeping optimizes the glymphatic system—your brain's overnight cleaning crew that removes harmful proteins during deep sleep. Dr. Brain Good's 3-step sleep position protocol helps optimize this natural detoxification process to protect against cognitive decline.
