There are many statements about this kind of health preservation in my previous content. Interested partners can browse through the historical content. Of course, it is not just empty talk to dig and interpret these health proverbs, but to open your mouth. These truths are all from ancient books. I hope my interpretation can bring you some help.

The first sentence: Don't spit in the morning.

In the previous content, it was often mentioned that in the middle of the night, the yang in the kidneys began to rise. In the morning, the kidney qi in our body has risen to full, and it should be time to feel refreshed. In our kidneys, the liquid is saliva. And this "saliva" means our saliva. When the kidney is full in the morning, the saliva in the mouth will be full of kidney, and its texture is thin, which is conducive to nourishing yin and benefiting the kidney. If swallowed directly, it will be of great benefit to nourish our kidney qi. That's why they say "Don't spit in the morning".

The above records are not "mystifying" by the ancients. According to modern medical research, although saliva is mostly water, there are also many trace elements and protein. Saliva helps digestion and diminish inflammation. Its "parotid hormone" composition is also of great benefit to the human body. So "don't spit in the morning" makes sense.

The second sentence: Don't sweat at night.

Because at night, our Wei qi will be hidden inside, and the kidney yang is deep. At this time, you should relax and have a good rest to adapt to such physiological changes. Body fluid is also one of the carriers of qi. If you sweat and are tired in the middle of the night, the gas in our body will leak out with the body fluid. This is not conducive to defending qi and storing kidney yang.

If Stephy and kidney Yang Can are not hidden, they will easily go up and down the next day. In the long run, it will affect our physical condition. Plus the low temperature at night. If you sweat a lot at this time, the "gate of hell" will open, so cold and dampness will easily invade our bodies and make us sick. So "don't sweat at night" is well founded.

Of course, with the great changes in our living conditions and lifestyles, the statement that we don't sweat at night may not be 100% accurate. But in any case, after 10 in the evening, it's time to relax and rest, "shut the hell up and hide the gas." If we sweat again, it will damage our health.
