Is it normal not to catch a cold for a year?

Because people have different physical conditions, some people often catch colds and fevers, while some people don't get sick for a long time, and some people don't even catch a cold for a whole year. But there are always two sides to every coin. People who don’t catch a cold all year usually have stronger constitutions, but if these people get sick, it is very likely that they will have a more serious illness. So, is it normal not to catch a cold for a year?

On the one hand, not catching a cold for a long time can mean that your immune system is strong, but have you ever heard of cancer? People who often catch colds have a lower risk of cancer, as cancer cells will be killed when the body temperature rises.

Not catching a cold can easily lead to cancer

Things are always divided into two. Although colds are considered the root of all diseases, if a person has a cold and it is not properly treated, it will lead to a variety of complications, directly threatening human health. However, people who rarely catch a cold in their lives are more likely to develop cancer.

According to foreign media reports, scientists have long discovered that many people who die of cancer rarely catch a cold.

After investigation and analysis, German scientist Professor Zankel and his colleagues pointed out that people who catch a cold less than once a year have a five times higher chance of getting cancer than those who catch a cold several times a year. Why is this? The current medical community believes that when a person catches a cold, the body's immune system reacts to the cold virus and produces an "interferon," which activates the immune system's "combat cells" to destroy cells invaded by the cold and cells that have a tendency to become malignant.

Every time the human body experiences a cold, the body's immune system will produce this interferon to protect normal cells from viral infection, inhibit viral reproduction, destroy diseased cells or slow down the division of certain cancer cells, and enhance the immune system's resistance to cancer cells.

The latest research results show that cold viruses can directly kill cancer cells. Therefore, some people regard colds as the nemesis of cancer.
