First, one's physical fitness is good, and one's immunity is good without fever for a long time.
Good constitution and good immunity. How to judge the quality of constitution? It needs to be judged according to resistance, color, sleep quality and digestive system. Generally speaking, you have good complexion, good sleep quality, good digestion, good resistance (immunity) and good physique. Judging the quality of physique according to the quality can also judge the quality of immunity. For people with strong physique, often not having a fever means stronger immunity and better resistance. When viruses, bacteria and other pathogenic microorganisms invade the body, their immunity can quickly destroy them. If you have good immunity, you won't have a fever, a cold or a runny nose.
Second, personal physique is too weak, and long-term absence of fever is the loss of resistance.
It is not a good thing for people with poor resistance, poor sleep and bad complexion not to have a fever for a long time, which just proves that they have lost their resistance and their reaction to not having a fever. If you can't have a fever, you can only let bacteria and viruses invade your body. Such people suggest going to the hospital to check their immune system function and central nervous system function. At the same time, it is also suggested to insist on physical exercise, pay attention to nutrition collocation, ensure sleep quality, avoid staying up late, combine work and rest, and improve one's physique and immunity.
Finally, in the face of medical problems, we should learn to distinguish rationally, don't listen to the wind as rain, and listen to the doctor's advice if there are problems. Good health is the first in our life and our capital. Without a healthy body, everything is zero. We should pay attention to our health. Pay attention to exercise, diet and health. Only in this way can we ensure our health and future life.
