It has been pointed out that the human body should adjust its breathing rhythm according to the "fifty battalions". The so-called fifty camps refer to the movement of meridian qi in the human body according to certain rules, and it runs around the whole body for 50 times a day and night. This emphasizes the need to take the form of deep, long and slow breathing, which is equivalent to a breath of 6.4 seconds and a breath after conversion. It is the best rhythm for ancient people to breathe and keep healthy.

Breathe slowly in four words: deep, long, even and thin. Taking a deep breath means that every breath will end; Long, the time should be lengthened and the speed should be slowed down; Uniform symmetry; Fine is fine, not rough. Practice consciously when you start breathing, and it will be natural over time. It can also strengthen respiratory function and promote pulmonary circulation. At the same time, strengthen intra-abdominal self-massage, improve abdominal blood circulation and enhance gastrointestinal peristalsis. But be careful to breathe through your nose, not your mouth.

In addition to slow breathing, the ancient concept of slow health preservation also includes slow brain use, slow exercise, slow eating, slow sleeping, slow talking, slow walking, then slow heartbeat, slow breathing, slow consumption, and finally slow aging.

Although modern people don't have to stick to the ancient way of keeping in good health, for office workers, slow keeping in good health should be the adjustment of fast-paced life. You can keep a fast pace in 8 hours of work. After work, you should slow down and relax the tight strings. The day is tight and the night is loose. "Hurry up and slow down" can make the string of life elastic.
