What are the dangers of electromagnetic fields to people? The harm of electromagnetic fields to the

The hazards of electromagnetic fields to human health are divided into somatic effects and population effects.

Somatic effect: divided into thermal effect and non-thermal effect, the mechanism of thermal effect has been well understood, after the human body receives electromagnetic radiation, the water molecules in the body will move rapidly with the conversion of the direction of the electromagnetic field and heat up the body. If a large amount of radiation energy is absorbed, and the absorbed heat cannot be dissipated by the regulation of body temperature, it will cause an increase in body temperature, which in turn will cause various ...

symptoms. The mechanism of non-thermal effects is not well understood, but it does exist: the absorption of insufficient radiant energy to cause an increase in body temperature but a biological change or response occurs.

Such effects include neurasthenic syndrome. Electromagnetic radiation has also been reported to cause cancer.

Population Effect: The population effect is not observable for a short period of time, and may make humans smarter, or on the contrary, it may affect human development. The effects of electromagnetic fields on the human body should have different consequences due to different frequencies of electromagnetic fields.

Electromagnetic field refers to a physical field consisting of an electric field generated by an electric charge and a magnetic field generated by an electric current. They are found in various electrical devices around us, such as mobile phones, televisions, computers, microwave ovens, etc. Although the electromagnetic field has brought a lot of convenience to the production and life of human beings, long-term exposure to high-intensity electromagnetic fields may cause harm to the human body.

Let's take a closer look at the dangers of electromagnetic fields to the human body.

Effects on the nervous system:

Long-term exposure to high-intensity electromagnetic fields may cause abnormal reactions of the human nervous system, such as headaches, insomnia, nervousness, memory loss, etc. This is because electromagnetic fields can interfere with the normal functioning of the human nervous system, affecting the transmission and reception of nerve signals, which can lead to disorders and discomfort of the nervous system.

Effects on the cardiovascular system:

Long-term exposure to high-intensity electromagnetic fields may affect the normal function of the human cardiovascular system, such as increased blood pressure, irregular heart rate, etc. This is because electromagnetic fields interfere with the circadian rhythm and metabolic functions of the body's cardiovascular system, which can lead to disorders and discomforts in the cardiovascular system.

Effects on the immune system:

Long-term exposure to high-intensity electromagnetic fields may affect the normal function of the body's immune system, such as decreased immunity and susceptibility to infection. This is because electromagnetic fields interfere with the normal functioning of the body's immune system, affecting the body's ability to recognize and defend against external pathogens, resulting in disorders and discomfort of the immune system.

Effects on the reproductive system:

Long-term exposure to high-intensity electromagnetic fields may affect the normal function of the human reproductive system, such as decreased reproductive ability and abnormal levels of sex hormones. This is because electromagnetic fields interfere with the normal physiological functions of the human reproductive system, affecting the generation and development of reproductive cells, resulting in disorders and discomfort in the reproductive system.

In conclusion, the effects of electromagnetic field hazards on the human body are manifold. Although modern technology has taken a series of measures to reduce the impact of electromagnetic radiation on the human body, we still need to pay attention to reducing the chance of being exposed to high-intensity electromagnetic fields for a long time, maintaining a reasonable distance and using time, so as to reduce the harm of electromagnetic radiation to the human body.

The magnetic field is a special substance that cannot be seen or touched, the magnetic field is not composed of atoms or molecules, but the magnetic field exists objectively. The magnetic field has the radiative properties of wave particles. There is a magnetic field around the magnet, and the interaction between the magnets is mediated by the magnetic field, so the two magnets can act without contact.

Magnetic fields are harmful to people.

Since the magnetism of a magnet is the same as the current, the current is the movement of an electric charge, so in a nutshell, the magnetic field is generated by the change of the moving charge or electric field. From the point of view of modern physics, the only ultimate components that can form a charge in matter are electrons (with a unit negative charge) and protons (with a unit positive charge), so the negative charge is a point object with excess electrons, and the positive charge is a point object with excess protons.

The real source of the field where the moving charge produces the magnetic field is the magnetic field produced by the moving electrons or moving protons. For example, the magnetic field generated by an electric current is the magnetic field generated by electrons moving in a wire.
