1, age
Many factors will affect the strength of immunity, especially health and age. From infancy to old age, immunity will become stronger and stronger, because they have more and more contact with the outside world, and antibodies will gradually be produced, and immunity will reach its peak in adolescence. After adulthood, immunity will gradually decline with age. Especially after entering the age of 65, it is easy to get infected with the virus and it is difficult to recover.
2, easy to get sick and catch a cold
It takes a long time to get well after a cold, which is a symptom of low immunity. Such people should pay attention to environmental hygiene, take part in more physical exercises and strengthen their physique.
3. Energy difference
Feeling weak and tired, without any spirit, chronic fatigue is closely related to the immune system. Lack of energy is a sign of imperfect immune system.
4. Wounds are susceptible to infection
Wound healing can be divided into four stages: hemostasis, inflammatory proliferation and reconstruction, in which enough immune cells are involved. People with strong immunity can recover quickly, and immune cells can promote the recovery of chronic wounds and skin regeneration. On the contrary, people with poor immunity are prone to infection and difficult to recover.
Step 5 take medicine regularly
As the saying goes, drugs have three kinds of toxicity, especially antibiotics. Although it can kill bacteria, it will disturb the intestinal flora environment and reduce the immune system. If antibiotics are used frequently, macrophages will be inhibited by respiration, thus increasing the risk of infection.
6. bad temper
Always angry, being under high pressure for a long time will increase cortisol. In this state, immune cells will disappear from the blood, and viruses will take advantage of it, thus inducing diseases. However, as long as such people release stress in time and exercise more, they can improve their immune status and reduce the risk of infection. Long-term depression can damage the immune system, change the immune response and increase the risk of inflammation.
7. Poor sleep for a long time
When people fall asleep, the immune system can release cytokine proteins. When infected by virus or bacteria and attacked by inflammation, the demand for cytokines will increase. Long-term lack of sleep will hinder the production of protective cytokines and reduce anti-infective antibody cells. Such people have poor immunity.
