American physicists find that using magnetic fields can reduce human blood viscosity

If people's blood is too thick, it may increase blood pressure, damage blood vessels, and increase the risk of heart attack. (This is the default cause of elevated blood viscosity and hypertension, cardiovascular disease, but in fact the two can only be considered related, more likely is that both are the same reason, namely, arteriosclerosis, plasma fiber The result of zymogen elevation). According to the report of the American Physicist Organization Network on June 8 (Beijing time), physicists at Temple University in the United States recently discovered that the use of magnetic fields can reduce human blood viscosity. Research papers were published in the recently published "Physical Review E".

Currently, the only way to dilute blood is to use drugs such as aspirin, but these drugs can cause side effects. Tao Rongjia, a professor at Temple University who had invented a method to reduce the viscosity of oils in engines or pipelines by electric or magnetic fields, has extended this method to the control of blood viscosity. After testing a large number of blood samples, he discovered that Magnetic fields can also dilute blood in the human circulatory system.

Because red blood cells contain iron, the application of a magnetic field can polarize red blood cells, connecting them in the form of short-chain, streamlined movements. Since these short chains are larger than a single blood cell, they flow down toward the center, with the blood vessel walls. The friction will be reduced. This connecting effect reduces blood viscosity and helps them flow more smoothly. Applying a magnetic field of 1.3 Tesla to the blood for about 1 minute will reduce the blood viscosity by 20% to 30%, which is equivalent to the magnetic field intensity of magnetic resonance imaging. When the magnetic field is removed, blood will gradually return to its original viscous state in the blood vessels, but this will take several hours.

"By choosing the appropriate magnetic field strength and pulse time, we can control the size of the red blood cells aggregated into chains and thereby control the blood viscosity. This method of magnetorheological provides an effective way to control within a selectable range. Blood viscosity.” Tao Rongjia explained that this method is not only safe but also repetitive. It can reduce blood viscosity by applying multiple magnetic fields, and the decrease in viscosity does not affect the normal function of red blood cells.

Tao Rongjia also said that the method still needs further research and plans to apply for funding for clinical trials.

1.3 The magnetic field of Tesla's magnetic field and magnetic therapy are different. It's like the difference between high voltage power and 1.5V battery. The magnetic field strength is about 1 Tesla, which is 20,000 times that of the Earth's magnetic field. It is about 10 to 100 times that of a magnet in a radio horn. Not only that, this is helpful for lowering the viscosity of blood, but human cells are also diamagnetic and do not know any negative effect on other cells.

In the original report, "this intensity is only equivalent to the magnetic field strength of magnetic resonance imaging." Here "only" means that this intensity is safe because NMR is considered to be safe.

About 1.3 Tesla is the main field strength of the past human body MRI diagnosis and experiment, the old hospital equipment is still 1 Tesla to 1.5 Tesla. The current new equipment is based on 3 Tesla, which is considered conventional. 7 Tesla counts high field strength, but some people use it but less. At present, all of the biophysics of the Chinese Academy of Sciences in Beijing needs to be very careful when doing human experiments. No matter which of the above, magnetic shielding rooms and inspections are required. For example, implants (steel spikes implanted from pacemakers to fractures to artificial penis) can be dangerous and generally not.
