Lack of deep sleep

Lack of deep sleep is common in obstructive sleep apnea syndrome. During deep sleep, human cerebral cortex cells are in a state of full rest, which is extremely important for stabilizing emotions, balancing mentality, and restoring energy. At the same time, many antibodies can be produced in the body to enhance disease resistance. Research shows that the first 3 hours of falling asleep are important because during this time, deep sleep accounts for almost 90%.
