Briefing on the Relationship Between Disharmony of Ying and Wei and Senile Sleeplessness

Senile sleeplessness refers to the morbid state with insomnia of people over sixty years old. When ying and wei qi flow externally, yang prevails and people have a clear mind during the day. When they flow internally, yin prevails and people go to sleep at night. People of old age have weak constitutions and less ying and wei qi. Therefore the disorder of flow of qi will cause imbalances of qi, blood, yin and yang. Restlessness is the essential cause of senile sleeplessness. So it is important to regulate ying and wei, which includes regulating mentality and diet, and treatment with drugs.
