The harm of computer radiation to people

1, too long computer use is the key to hair loss;

When the brain is highly concentrated on using the computer, the excitement of the brain will increase for a long time, and endocrine will be disordered. Sebaceous glands connected with hair follicles will secrete too much, leading to hair follicle embolism, blocked hair nutrition supply, brittle hair and hair loss. For slight hair loss, it can be alleviated by reducing computer use time and adjusting lifestyle.

2. The light emitted by the computer screen contains a lot of high-energy short-wave blue light with irregular frequency and extremely high energy, which can penetrate the lens and reach the retina.

Blue light will produce free radicals, which will lead to the decline of retinal pigment epithelial cells, and the decline of epithelial cells will lead to the lack of nutrition of photoreceptor cells, resulting in visual damage. These "inappropriate lights" are the chief culprit of macular degeneration (AMD), a large part of senile blindness.

Extended data:

1, radiation principle:

Radiation is emitted in the form of electromagnetic waves and particles (such as alpha particles and beta particles). Radio waves and light waves are electromagnetic waves. Their propagation speed is very fast, and the propagation speed in vacuum is the same as that of light waves (3×10.8 m/s).

2, the main classification:

Visible light also belongs to radiation, which can be generally divided into ionizing radiation and non-ionizing radiation according to its energy level and the ability to ionize substances. This term is usually used for ionizing radiation.

Ionizing radiation has enough energy to ionize atoms or molecules, but non-ionizing radiation does not. Radioactive substances refer to substances that can emit ionizing radiation. There are three main types of ionizing radiation: α, β and γ radiation (or rays).
