Sun Simiao, the "King of Medicine", thinks that "more words will lead to less gas" and asks people not to talk too much. Talking too little can nourish qi, otherwise it will dissipate qi. Chinese medicine believes that talking too much will consume qi and hurt yin, and for a long time, it will also lead to both qi and blood injuries, which is easy to fatigue and insomnia.

In severe cases, sleep will also be affected. This is because talking too much, qi and blood rushing up, always in a divergent state, unable to recover and restrain, so sleeping always makes people dream more and sleep restlessly. Therefore, Chinese medicine advocates silent health preservation.

Silent health: eat without talking, sleep without talking.

Talking less about keeping in good health means that you can't let your anger dissipate at will. This needs to start from the dribs and drabs of daily life, such as avoiding talking constantly. Keeping in good health is not not not talking. Proper chatting is a kind of emotional catharsis, which is beneficial to physical and mental health.

Ancient people's health care provided "eating without words, sleeping without words". Because when people talk, it is easy to excite the brain and make their thinking active, thus affecting sleep. Therefore, people should not talk much before going to bed.
