Qigong, as a method of strengthening lung, can improve human immunity, enhance lung function, enhance the ability of human body to absorb and utilize oxygen, and at the same time, it can relieve fatigue and refresh the mind.
The simplest closed qigong can be understood as holding your breath. That is to say, just inhale without exhaling or just exhale without inhaling. But this is certainly not the whole of closed qigong.
How to practice qigong is to find a place with fresh air, preferably not on the roadside where cars are coming and going or in a crowded public place.
Take three to five deep breaths to expel the waste gas from your body, and at the same time relax your body and calm your mood.
Inhale naturally, not too fast and not too slow. Inhale until you can't inhale any more, let the gas be stored in your chest and abdomen, and you can hold your breath. When it can't be closed, you can breathe in quickly through your nose without exhaling, so you can exhale until you can't breathe in again and stop breathing.
Hold your breath once, take a few deep breaths, and then start the second, fifth or tenth time.
Precautions for practicing Qi-closing Qigong: Do not practice in polluted air, otherwise the polluted air inhaled at the initial stage of Qi-closing and after Qi-closing will do more harm to the body.
When practicing, keep your mind at peace and don't worry, so you can get twice the result with half the effort.
If you can't hold your breath, you don't have to force it deliberately. It's not the principle of keeping in good health to go against the natural laws of the body.
This kind of exercise has a small time limit, but it is not suitable to pursue the number of times to hold your breath at a time. Not many times each time, but you can do it several times a day. The key is long-term persistence.
This method can be practiced standing, sitting or lying down, not too rigid.
The advanced practice of Qi-Holding Qigong is to hold your breath after breathing until you can no longer hold your breath. Breathe once, then hold your breath, and so on. This method shortens the recovery time of the body after holding the breath, and is an advanced method of the former method.
Hold your breath after exhaling, that is, inhale first, exhale again, breathe until there is no breath, and then hold your breath without inhaling. This method emphasizes the adaptability of the body to hypoxia, but in terms of health care effect, it is not as natural and smooth as the method of holding your breath after taking a deep breath.
