Hey, if you just want to sleep, you really don't need to practice Tai Ji Chuan. Tai Ji Chuan is mainly for health preservation. If you have to choose, yoga is definitely more suitable, because yoga belongs to guiding qigong and has a better effect on regulating physiological and psychological balance. It is not recommended to learn Tai Chi because if you don't have the guidance of knowledgeable people, you may even hurt your body, especially your knees. I really don't lie to you. And Tai Ji Chuan really doesn't help you sleep much. There are many ways to help sleep, all of which are better than practicing Tai Ji Chuan. Tai Ji Chuan's advantage is to adjust people's psychological balance and mentality, so that people can forget their anxiety, but if you insist on practicing for sleeping, you must pay attention to protecting your knees. This is the reason why many of our family-run boxers have pain in their knees when they are old. On the contrary, when the elderly are free, because they basically don't meet the requirements of Tai Ji Chuan, their legs and waist are not up to standard, and they basically stand and punch.
