Do you prefer lying on your back, prone or on your side? The latest survey report in the United States shows that the sleeping posture may affect the operation of the human brain: lying on one’s side is more helpful to the human brain, conducive to self-cleaning of the brain, and can also reduce the incidence rate of neurological diseases such as Alzheimer’s disease.
According to the report of the US science and technology news website future, sleeping on one’s side is more helpful to the human brain than sleeping on one’s back or on one’s stomach. It is reported that side sleeping is conducive to self-cleaning of the brain, and can also reduce the incidence rate of Alzheimer’s disease, Parkinson’s disease and other neurological diseases.
better sleep quality
Researchers say that after a hard day’s work, the human brain will produce various amyloid proteins, such as β Protein, etc. These proteins are “wastes” left by the brain after working for a period of time. In addition to seriously affecting the normal operation of the brain, they may also induce Alzheimer’s disease and other major neurological diseases.
At this time, in order to clean up “waste”, the lymphoid system in the brain appears. This complex system can identify and dispose of the “waste protein” in the brain through a series of cleaning and dissolution processes, so as to provide a clean “working environment” for the brain.
The researchers used magnetic resonance imaging technology to study the transport rate of lymphoid system in the brain of mice in different sleeping positions (supine, lateral and prone).
“We found that, compared with lying on the back and prone, the transport of lymphoid system in the rat brain is most efficient when lying on the side,” said Professor Helene benvinist of Stony Brook, State University of New York. “That is to say, lying on one’s side can make the brain eliminate waste more efficiently.”
the most suitable sleeping position
Researchers used fluorescence microscopy and emission tracking to measure and analyze the effect of different sleeping positions on the clearance of “waste protein” in the brain. “This discovery is very interesting!” Professor McCann niedergaard of the University of Rochester in the United States said, “lying on one’s side is the most commonly used sleeping posture for humans and even most animals, as well as wild animals! This clearly shows that the brain has chosen the posture that is most suitable for its self-cleaning.”
