First, the official holiday is detoxification.
I've heard this rumor before. Some people say that women are detoxifying when they come to menstruation. The director of Obstetrics and Gynecology of Peking Union Medical College Hospital came forward to refute the rumor, saying that women's menstrual period does not belong to detoxification, and it is not a good thing whether it is too much or too little. Menstruation is a physiological phenomenon of women, and it also represents a sign that women can reproduce normally. Menstruation is mostly blood, except for some substances such as endometrial debris, which belongs to normal metabolism and has no toxin. If you have more holidays, you may have some kind of disease. If the menstrual flow is too small, endocrine problems may have an answer.
Second, blood vessels are blocked.
There was a rumor before that if the blood vessels were blocked by 20%, people would feel nothing. If the blood vessels are blocked by 40%, the whole person will be very tired. If the blood vessels are blocked by 50%, the blood pressure will rise. In this way, the degree of blood vessel blockage can be judged. In fact, these are just lies, the main purpose is to sell their own things. 20% of people with blocked ventricular blood vessels have no symptoms. If the blood vessels are blocked to more than 50%, then symptoms may appear, but the symptoms vary from person to person, and even some people are blocked to 80% without those symptoms mentioned above. Therefore, if you want to keep blood vessels unobstructed, you must have good living habits, pay attention to exercise at ordinary times and follow the doctor's advice.
Third, hold your breath to test lung health.
The director of Tianjin Medical University came forward to refute the rumor, saying that holding your breath is not directly related to lung health. I believe many people should have done this kind of experiment, but many people also said that they almost felt sent away after holding their breath for 30 seconds after the experiment. If you suspect that there is something wrong with your lungs, you must go to the hospital for examination, instead of holding your breath for self-examination.
