There is a theory that a person shudders falling asleep from the fact that a protective mechanism is triggered. The brain feels that the body is relaxed, breathing is slowed down, and these are signs of impending death for it. This is how he cheers us up.

This phenomenon is nothing more than a muscle spasm. While the human body begins to fall asleep, there are a lot of sodium molecules in the muscles, which are responsible for their contraction. As soon as the muscle tone decreases, due to a decrease in the motor center of the cerebral cortex, the muscles dramatically release all excess sodium from the cells. Which leads to an involuntary contraction.
