The Best Sleeping Position to Prevent Alzheimer’s and Memory Loss
Sleep is not just rest for the body
it is a vital process during which the brain repairs itself, organizes memories
and clears out toxins accumulated throughout the day.
Recent studies suggest that sleeping position may play a significant role in long-term brain health and could even help reduce the risk of Alzheimer’s disease and memory decline.
Sleep and Brain Health
During deep sleep, the brain activates the so-called “glymphatic system,” a network of channels that flushes out toxic proteins such as beta-amyloid and tau.
The buildup of these proteins is considered a hallmark of Alzheimer’s disease. If they are not effectively removed, they can accumulate over time, leading to memory loss and cognitive decline.
The Best Sleeping Position for the Brain
Research from Stony Brook University in the U.S.
shows that sleeping on one’s side
whether right or left—is the most beneficial position for brain health.
Experiments on animals revealed that side sleeping allows the glymphatic system to function more efficiently compared to sleeping on the back or stomach.
In other words
- side sleeping helps the brain clear out toxins faster
- and more effectively, potentially lowering the risk of
- memory impairment and neurodegenerative diseases like Alzheimer’s.
Why Other Sleeping Positions Are Less Ideal
Sleeping on the back: While comfortable for some, it may slow down brain cleansing. It can also increase snoring and sleep apnea, which negatively affect sleep quality and long-term memory.
Sleeping on the stomach: This position puts pressure on the spine and causes neck and back pain. It can also restrict breathing, which reduces deep sleep and weakens glymphatic function.
Tips for Improving Side Sleeping
-
Choose the right pillow: It should fill the space between the shoulder and neck to keep the head aligned with the spine.
-
Use a pillow between the knees: This reduces strain on the spine and keeps muscles relaxed.
-
Switch sides: Alternate between right and left to avoid shoulder stiffness or joint pain.
-
Maintain a consistent sleep schedule: Going to bed and waking up at the same time improves deep sleep cycles.
-
Limit screen time before bed: Blue light from devices suppresses melatonin production, disrupting sleep quality.
Sleep as a Preventive Strategy
- Sleeping position alone cannot prevent Alzheimer’s or memory loss
- but it is part of a healthy lifestyle that includes good nutrition
- physical activity, and stress management.
Still
choosing to sleep on your side may be a simple yet powerful habit to support brain health and preserve memory in the long run.
Conclusion
Sleep is not a luxury
it’s a necessity for maintaining brain function. If we want to lower the risk of Alzheimer’s and memory decline, side sleeping appears to be the best position.
A small habit
but one that can make a big difference in protecting our minds for the future.
