First: in most cases, fever is not a disease, but a protective response of the body to the invading pathogen, that is, the body is launching the immune system to resist infection. In fact, the physiological mechanism of fever is that white blood cells find the pathogen invaders, and then release proteins to stimulate the hypothalamus to raise the temperature.

Second: as the saying goes: "worry about a worry, white head." Sentimental people's immune function is easy to reduce, the ability to kill pathogenic microorganisms is weakened, the level of interferon is decreased, and the respiratory defense function is decreased, so that the cold virus has an opportunity.

Third: a medical expert observed more than 400 unemployed, unemployed, divorced and other people with mental stress, and found that they are more likely to catch a cold than people without mental stress, because the antiviral substances such as interferon and nuclease in the nasopharynx are significantly reduced, and the local immunity is reduced.
