In daily life, do you often hear such words: "So-and-so usually can't even catch a cold, and I can't imagine that I have cancer all of a sudden?"
This gives us the illusion that people who have not been sick for a long time are more likely to get seriously ill, is this really the case?
Immunity of the human body,
After the age of 35, it decreases with age
First, let's talk about how the body's immune system works
The immune system is actually the "police" of our body, responsible for fighting off foreign invaders such as viruses and bacteria. It's like a huge army, with soldiers and commanders, as well as scouts. When we are sick, the immune system is mobilized to identify viruses and bacteria, sweep away enemies, and allow us to defeat colds and other diseases.
When is the body's immunity at its strongest?A study published in the well-known medical journal Nature Immunology at the University of Texas Southwestern Medical Center in the United States showed that researchers analyzed the migration of immune cells in mice and humans and found that the peak of immune cell activity was around 8 o'clock in the morning.
In the life of a person,Immunity inIt peaks around the age of 20, after the age of 35, the immunity decreases with age, and after the age of 65, the immunity declines even more precipitously
People who do not get sick for a long time
Are you really more likely to get cancer?
Some people rarely catch a cold or rarely have a fever for two possible reasons:
On the one hand, there is the immune system"Tough".As soon as viruses and bacteria invade, they are recognized and discovered by the immune system, which means that viruses and bacteria are eliminated when they are still in the bud, and of course there will be no cold and fever.
On the other hand, personal protection is done wellWearing a mask when going out, washing your hands when you get home, and doing a good job of self-protection in crowded crowds and closed places reduces the chance of virus and bacteria invading.
As for people who rarely have a cold and fever are more likely to develop cancer, this statement has no scientific basis。People who rarely have a cold and fever indicate that they have better immunity, and it is obviously unscientific to say that such people are more likely to develop cancer.
Why do some people think that people who don't have a minor illness are seriously ill when they get sick?In fact, this is our "sensory error", because people who are in good health rarely get sick, even if they encounter a cold and don't need to take medicine, these people rarely go to the hospital, so when they find a serious illness, it will form a strong contrast and make people impressive.
Health and disease prevention,Do these three things in your life
Regular medical check-ups:Whether you have a frequent cold or not, regular check-ups are an effective means to prevent serious illnesses. Through a medical check-up, potential health problems can be detected early and worsened.
HealthlifeGood lifestyle habits are the basis for disease prevention. Eating right, getting enough sleep, quitting smoking and limiting alcohol can all strengthen the body's resistance.
3. Regular exercise:Exercise can improve the function of the respiratory, cardiovascular, digestive and nervous systems, and about 30 minutes of aerobic exercise 4 or 5 times a week will bring benefits to both physical and mental health.
In short, the function of the immune system is very important for health, we must protect our own immunity every day, and we should also pay attention to the body's signals, which may be a sign of a serious illness.
