For example, when we are studying, although we don't do manual work, we will feel particularly tired. That's because all our blood is used in the brain, and the blood is reduced. So if you think too much, even if the meridians are unblocked, you will feel particularly tired.
When the meridians are unblocked, our bodies will feel particularly lazy, and the whole person will feel lazy. At this time, I will feel particularly tired, even if I lie down, I feel particularly soft. Then I don't want to do anything. It's like being there all the time.
And when we dredge the meridians, other blood supplies of the body will be transported there. Therefore, even if the meridians are unblocked, but our contribution is reduced, our human body will feel particularly tired.
There is a particularly simple analogy. When we turn on the air conditioner, if we turn on the air conditioner in a narrow area, we will feel very cool, but if we turn on all the spaces, it will cost a lot of electricity and feel less cool.
Although it will be particularly tiring to dredge the meridians, you can't help but dredge them. You must insist on dredging them. When we clear all the meridians in the whole body, then we will feel particularly relaxed.
Besides, we can also eat some red dates and medlar to replenish qi and blood before dredging meridians, so that we won't feel so tired because of sufficient qi and blood.
In daily life, you must use the methods you see to dredge the meridians and pay attention to maintenance.
