Just like a cold is a disease that is good for health. In fact, many people will catch a cold in life, and some people will be afraid of catching a cold because they catch too many colds. However, a cold is not so terrible. A cold doesn't mean that you are in poor health or unhealthy. On the contrary, people who don't catch a cold all the year round should be more worried about their health. This is because, after we catch a cold, the human immune system will react with the virus and produce interferon to stimulate our immune system, thus making our body produce defense cells that can fight the influenza virus. Then, after frequent colds, our immune system can be gradually strengthened, which will increase our resistance, which will reduce our chances of getting cancer. Therefore, catching a cold often will not only harm our health, but also help to improve our immunity. Moreover, medical research has proved that, generally speaking, people who often catch a cold only once or twice a year are about five times more likely to have cancer than those who catch a cold many times a year.
In fact, in addition to catching a cold, many of us will encounter some other minor symptoms in our lives. As long as it is not life-threatening, it is likely to continuously stimulate our immune system and improve our resistance. Of course, in order to improve our resistance, besides physical stimulation and self-healing, we also need to maintain a healthy lifestyle. In life, we can do this to improve our resistance. First of all, it can keep the body slightly hungry and accelerate the metabolism of the body; Secondly, regular walking can improve our heart and lung vitality, thus improving the body's resistance; Finally, keep an optimistic attitude. A positive attitude is the greatest weapon to prevent diseases.
