Generally speaking, yoga rest is to restore energy quickly, but at night, it is to fall asleep as soon as possible. If you fall asleep during the day, you may feel a little tired when you wake up. Therefore, when you take a break from practicing yoga during the day, you may feel a little tired when you wake up. Therefore, when practicing yoga during the day, you must concentrate and practice for a relatively short period of time. If you fall asleep inadvertently during the day, yoga rest is to better absorb and integrate the information energy and function brought by yoga rest to the body, so that blood can circulate in the body for more time. If you sleep for more than 5-8 minutes, people's true qi will dissipate, because the heat energy that has been emitted-blood will flow to all parts of the body, but because of sleep, the blood of the human body will flow slowly, which is not conducive to the recovery of the human body. Actually, I just woke up after a short sleep. If you wake up before the air dissipates, you will feel very comfortable, but you will feel very tired after a long time.
