In India, qigong and qigong practitioners are collectively called yoga. A well-trained yoga can make your heart beat faster or slower without eating or drinking for days on end … and so on. The mysterious mystery of yoga has always attracted the attention of scientists all over the world. Yoga is very popular in India. Religious yoga has left a deep impression. At present, apart from religious yoga, there are many secular yoga in India. The latter abandoned the mystery of religious teachings and regarded self-cultivation as a means of health preservation, disease prevention and longevity. There are many yoga schools in India that specialize in teaching yoga, and many yogis go abroad to teach in Europe and America. 1935, Krishna Mahari, a yoga teacher in Madras province, claimed that she could stop her heart. French cardiologist Doris. Dr Blos observed him on the spot with a portable electrocardiograph. Krishna Mahari took a few breaths and then fell silent. After the experiment began, I couldn't feel the yoga pulse, couldn't hear the heart sound, and the electrocardiogram was in a straight line, which proved that my heart stopped beating. But people are alive, Doris. Blos's observation aroused more scientists' interest in yoga. 196 1 year, doctors in new Delhi observed three kinds of yoga that claimed to stop the heart. The observation results show that the pulse, blood pressure and heart sound of yoga have stopped, and only the electrocardiogram is in a normal curve. X-rays show that the diameter of the heart has become smaller. This proves that the activity of the heart is extremely weak because of its miniature size. How does yoga control your heart activity? Yoga has two performing processes: first take a deep breath, then hold your breath, and expand the chest muscles and abdominal traces of laryngeal hunger. Doctors believe that this method can greatly increase abdominal pressure, thus greatly reducing the flow of venous blood into the heart. As a result, the ventricular congestion is insufficient, the heart activity is greatly weakened, and the volume is gradually reduced, so that no pulse can be felt from the body surface, no blood pressure can be measured, and no heart sounds can be heard. Of course, only yoga after years of exercise can produce this magical effect in this way. Ordinary people should never try it easily, because it is likely to lead to fainting or even death. The third meditation method of yoga is to shrink the abdomen sharply and lift the abdomen above the diaphragm. Doctors believe that this method can strengthen the tension of vagus nerve, thus weakening heart activity. Interestingly, these doctors also found 1935 Doris. Blos observed yoga at Mahari in Krishna at the age of 67. He agreed to repeat the performance of that year, but he was worried that he would be too old and the effect would not be good. He said that without a month's preparation, kung fu can't come out. He also performed the action of increasing the internal pressure in the chest. Several other observations were the same as last time, except that this ECG drew a curve. Doctors in new Delhi think Doris's last time. The straight line recorded by Blos may be caused by technical error. From 65438 to 0968, scientists observed a "buried alive" yoga performance more carefully. Four performers (one is a professional yoga, two are secular yoga who have studied Qigong for three years, and one is a healthy person who has no yoga skills) went down to the tomb, with the loess capped and no pores left. Professional yoga stayed below for eighteen hours, and the other three stayed for fourteen hours each. Experiments show that the oxygen demand in the tomb is greatly reduced by both professional yoga and ordinary experimenters. What is the reason? Physiologists have long known that if people inhale air with high carbon content, the cerebral cortex and subcutaneous layer will be oppressed, which will relax muscles, weaken visceral activity and reduce endocrine, and the result will inevitably be reduced oxygen demand. Therefore, it is normal for people to reduce their oxygen demand in graves with high carbon concentration. Another point can also explain the correctness of this judgment, that is, the tested yoga can not bear the reduction of oxygen content in the air outside the tomb. Doctors from Uttar Pradesh Medical College in India made an incredible observation on yoga. A yoga named satya Murti was "buried alive" in full view for eight days and eight nights. The process of the experiment is as follows: first, dig a grave, without putting any food, only put five liters of distilled water into it. According to yoga, this water is not for drinking, but for moistening the air. At the end of the experiment, there was still half water left. The temperature in the cave is between 24 and 33 degrees Celsius. After eight days and eight nights, the tomb was opened, and yoga still sat there as it did at the beginning of the experiment, but the whole body was numb and unresponsive to the changes around it. The body temperature dropped sharply, only 34.8, and it was 37.2 at the beginning of the experiment. When the fence was just opened, the yoga body trembled violently, and after two hours, the body temperature returned to normal. During the experiment, yoga lost 4.5 kilograms and increased blood sugar. In particular, during the experiment, the metabolism of yoga body not only did not stop, but also did not decrease significantly. After eight days and eight nights of testing yoga, I have been observing ECG, with only a few short breaks. The record of ECG was unexpected: after being buried alive for two hours, the heartbeat gradually accelerated, reaching 250 beats per minute on the first night! Until the first night, a straight line suddenly appeared on the electrocardiogram, which surprised the doctors. What does the straight line of ECG mean? The doctors thoroughly examined the instrument and proved that everything was normal and there was no problem. "Yoga is dead 1 The frightened doctors decided to stop the experiment immediately and pull out yoga. But the yoga assistant thinks there is no need to make a fuss. He said that yoga was still alive, but his heart stopped beating ... so the experiment continued. Half an hour before the end of the scheduled experiment, the electrocardiogram began to curve again, and the heartbeat record was 142 times per minute! What causes the electrocardiogram to look straight? It is still a mystery. If you disconnect the electrode plate and connect it yourself, you need to be familiar with ECG technology, and it is not one or two leads, but twelve leads! Besides, on the eighth day, how can yoga, which is in a state of numbness, connect its own electrodes? Of course, it is not credible to say that yoga stopped his heart, because his metabolism was normal during the whole experiment. The mystery of yoga needs further exploration by scientists.
