"If the human body is rarely attacked by viruses and bacteria, the immunity will not be exercised, then the natural immunity is not strong, so it is easy to get cancer!"
A person who pays special attention to health preservation, he usually likes to watch some health-related articles and videos. When browsing the web recently, he accidentally saw the remarks at the beginning. He was particularly worried because he hadn't had a fever for a long time, and he was afraid that he might get cancer. So I asked me: are people who rarely have a fever really more likely to get cancer? Today, the doctor’s good words will talk to you about this issue.
1. What is the relationship between cancer and immunity?
I saw a comment on the Internet before, as long as a person lives long enough, that person will definitely get cancer. Think about it carefully, this statement actually has some truth.
We all know that as long as a person is alive, it will undergo metabolism and the cells in the natural body will divide. Cells will age after a certain period of time. In order to have new cells to replace aging cells, the human body needs to divide to produce new cells.
gene mutation
cells are prone to produce problematic cells when they divide. Many of these cells are genetically mutated. The risk of mutated cells becoming cancerous is significantly higher In normal cells. In this way, the incidence of cancer should be very high. In fact, it is not the case.
We humans have a relatively powerful immune system, which not only has the ability to resist the invasion of foreign microorganisms, but also has a monitoring function. When human cells become cancerous, the immune system can quickly recognize it,And kill them in time, so under the condition of normal immunity, the human body is not easy to get cancer.
To some extent, cancerous cells are like criminals, and the immune system is like a policeman. When the immune system is strong, the immune system can kill cancer cells in time. However, as people grow older, their immunity declines. In this case, the monitoring function of the immune system will decline, and the immune system will not be able to effectively kill cancerous cells.
According to historical records, seldom had cancer in ancient emperors. This is actually related to the emperor’s low life span. The emperor itself is a high-risk occupation, which may be replaced at any time, and the pressure is relatively high, so the life span is generally short. Before many emperors had time to get cancer, they might have already passed away!
In summary, cancer is inversely proportional to the strength of immunity. When the immunity is strong, the risk of cancer will decrease, and when the immunity is low, the risk of immunity will increase.
2. People who rarely have a fever are more likely to get cancer. Is there a scientific basis for this?
People who rarely have a fever are more likely to get cancer. In fact, there is no scientific basis for this. As mentioned above, people with strong immunity are not easy to get cancer, while people with weak immunity are relatively easy to get cancer.
fever
For those who do not have a fever for a long time, their immunity is not bad, otherwise they will definitely be infected by virus, bacteria and other pathogenic microorganisms, and then fever will occur symptom.
However, some studies have found that fever may help the human body to fight cancer. In the 1960s, related researchers discovered an immune cell in the thymus ,Named T cell , it was later discovered that T cells play an important role in killing cancer cells.
immune cells
Some recent studies have shown that the increase in body temperature has a certain effect on the function and activity of T cells. Naturally, fever may help the body "anti-cancer".
In addition, scientists also discovered that cancer cells are resistant to heat. Under normal circumstances, normal human cells can survive for 1 hour at a temperature of 47°C, while cells will suffer irreversible damage at a temperature of 43°C.
Some friends may have questions. Since fever can help the body fight cancer, can fever be used to treat cancer? It seems to be ok, , but it needs to be noted that in order to kill cancer cells, the temperature needs to reach at least 43℃. In addition to damaging cancer cells, this temperature can also cause discomfort to the human body, such as convulsions, Increased heart rate, even respiratory failure, multiple organ failure, etc.
3. In order to prevent cancer, we still have to improve our own immunity:
Many people may think that to improve immunity, they need to eat some health products. In fact, I personally feel that it is completely unnecessary.
Staying up late
To improve immunity, comprehensive measures need to be taken. try to get rid of bad habits that affect immunity, such as staying up late, drinking, smoking, eating junk food, overwork, etc.
Walking
It is said that life is exercise. This is indeed true. Proper exercise can not only strengthen the body, but also enhance the body’s immunity and reduce stress.The exercise requires long-term persistence. If you fish for three days and dry the net for two days, the effect is definitely not good. The daily exercise time should be controlled at about 30 minutes, at least 5 times a week, and the amount of activity should not feel tired the next day. Exercise does not mean that the more vigorous the better, walking is a safer and suitable exercise for middle-aged and elderly people. Of course, you can also choose the exercise that suits you according to your own situation. It should be noted here that do not go out to exercise when the weather is bad, you can choose to do indoor activities.
Balanced diet
In addition to proper exercise, a balanced diet is also very important. can appropriately increase the intake of vegetables, fruits and high-quality protein. The vitamins contained in vegetables and fruits and the protein contained in high-quality proteins can help boost immunity. You should try to eat a light diet every day, try to adopt healthy cooking methods, such as steaming, boiling, etc., try to avoid frying, frying, smoking and other cooking methods.
Hypertension
In addition, if you want to improve immunity, you need to actively control chronic diseases. Many middle-aged and elderly people now have chronic diseases such as hypertension, diabetes , etc. These diseases are currently incurable and can only be controlled by long-term oral medications. The human body is a whole. If a chronic disease causes a decline in the function of an organ, it will definitely cause a decline in immunity.
For middle-aged and elderly friends, they generally suffer from insomnia, and most of them do not go to the hospital for help from a doctor. Insufficient sleep will also reduce immunity, so when middle-aged and elderly people have sleep disorders, they must find ways to adjust their sleep.
In addition, you also need to maintain a good attitude and drink water appropriately.
