Help: I suddenly felt a gust of wind blowing on my back when I slept late at night. When I woke up, the curtains were basically closed ~ ~ ~

Your situation can be explained by TCM theory and Taoist practice. Chinese medicine believes that a human body with sufficient healthy qi has the ability to naturally expel diseases. When the healthy qi in the body is sufficient, it will automatically expel pathogenic factors including wind, fire, summer heat, dampness, dryness and cold, which are also commonly known as pathogenic factors, pathogenic factors and so on. This is also the reason why some minor illnesses are sometimes cured without medication. As the saying goes, "healthy qi is sufficient, and evil spirits are eliminated by themselves." And your situation should be that some cold accumulated in the body is discharged, and it is relatively concentrated. People are in a state similar to silence, which is easy to detect. Although you feel the wind blowing, it should actually be the wind blowing outside your body. Don't panic, don't take this situation too seriously, just let it be.
