What is the relationship between electrical activity in human body and human health?

Electrical activity in human body is closely related to physical and mental health, and psychophysiological functions such as brain thinking, blood pressure fluctuation, heart beating, muscle contraction and gastrointestinal peristalsis are inseparable from bioelectricity. Bioelectricity produced by human body is alternating current with changing size and direction. When the heart is beating, dozens of cycles of ECG can be measured on the skin surface, and the voltage is about a few thousandths of a volt. When people are at rest, they can measure several tenths of volts of EEG on their scalp, which is about 10 cycle per second. With the development of electronic technology and the appearance of different electronic instruments, doctors use different instruments to detect human bioelectric activities, such as cell potential, EEG, ECG, EMG, retinal electricity and so on. To help understand the functions of various tissues and organs. For example, different waveforms depicted by electrocardiograph can show whether the left and right bundle branch conduction and myocardial blood supply are normal, which is helpful to diagnose coronary heart disease, arrhythmia and myocardial infarction. Electroencephalogram (EEG) magnifies the electrical activity of brain cells by 6.5438+0.00000 times and depicts it on recording paper. In the brain waves of normal adults, α wave (8 ~ 13 Hz) accounts for about 75%, and β wave (18 ~ 40 Hz) accounts for about 25%. If the proportion of alpha waves in adult brain waves increases, there may be insufficient blood supply to the brain; If θ wave increases, there may be inflammation. If the δ wave increases, we should be alert to the occupying lesions in the brain. When scientists explore the mystery of the brain, they go one step further. They input the whole, coherent and moving brain wave data into a computer for digital operation, and then describe the operation results as flowing geometric figures. This is a brand-new "brain image map" technology. Using the brain image depicted in this brain image map, "we can see whether a person's brain is simple or complex;" Whether it is left hemisphere advantage or right hemisphere advantage or overall horizontal advantage; Whether it is biased towards creative thinking or standardized thinking activities; Whether the psychological quality is full, energetic or simple and quiet; Whether emotional activities are relaxed or nervous, etc. "What an exciting and wonderful image it is to know yourself!

Studies have shown that the strength of human immunity is closely related to bioelectricity. Scientists have observed that people are cheerful, energetic and confident, and the emotional area of the brain will constantly generate special bioelectric current, which will be transmitted to the nervous system and immune system of the brain, making immune cells active, enhancing their phagocytic ability, and destroying invading bacteria and viruses in time and effectively. The bioelectric current emitted by this emotional area also has the magical effect of inhibiting cancer cells and HIV. Some cancer patients are not intimidated by cancer, but overcome cancer with confidence and live full of energy, thus recovering without drugs. Relevant experts believe that this is a good mood to promote the generation of bioelectricity, act on the immune system to make it play its best role, and make the "incurable disease" become a treatable disease.

Interestingly, both Qigong therapy and modern biofeedback therapy in China have achieved remarkable results. The reason is to make use of the objective existence of human bioelectricity and self-adjust through the guidance of ideas to make the abnormality return to normal. Qigong can be divided into dynamic and static categories. Quiet is mainly "quiet and empty, quiet and relaxed", which affects physiology through spiritual guidance, regulates people's body temperature, heart rate, heart rhythm and blood pressure, and makes the brain enter a sober and highly quiet state. From static to dynamic, the combination of static and dynamic, external training of meridians and internal training of viscera, regulating body yin and yang, so as to achieve the purpose of eliminating diseases, strengthening body and prolonging life. Inspired by Qigong, biofeedback therapy developed from gradual relaxation therapy. It uses biofeedback electronic instruments to display the detected bioelectrical signals of human body in the form of light color and sound, so that people can understand and judge their own physiological and pathological conditions, and learn to control and adjust themselves with their minds under the guidance of instructions, such as heartbeat rhythm, blood pressure rise and fall, etc. Medical practice has proved that it has good curative effect on many morbid psychological and psychosomatic diseases caused by social psychological stress factors such as hypertension, coronary heart disease, diabetes, ulcer, migraine, neurasthenia, intractable insomnia and menopausal syndrome.

With the research of bioelectricity in medicine, electrophysiology, a frontier subject, came into being. It will conduct extensive and in-depth research on the mechanism, characteristics and laws of bioelectric activity, as well as the basis of human psychophysiology and physical chemistry, knock on the door of "the secret of the mind-body world" and reveal the mysteries of the brain in electrical activity, information transmission, and the unique psychological quality, intellectual characteristics and creative ability of human beings. This is of great significance for us to prevent and treat psychosomatic diseases, fully develop and utilize brain resources and carry out artificial intelligence research. Bring exciting prospects.
