In recent years, respiratory diseases have become more and more numerous, such as new crown pneumonia, allergic rhinitis, colds, etc., which have caused us serious health problems and added a lot of trouble to our lives.
However, more and more people are beginning to believe that people who have not caught a cold for a long time have poor immunity and are prone to cancer.

The answer is no, a German study has shown that the average person who has a cold more than three times a year has never had a cold in five years, the risk of cancer is not particularly different, and as a normal person, he will definitely not get a few colds a year, if he does not have a cold for a long time is a high-risk patient for cancer, then most normal people in the world are afraid of cancer.
01
What is a cold?
A cold is a common respiratory illness, also known as an acute upper respiratory tract infection, which is caused by a viral infection, usually spread through droplets. Symptoms of a cold include nasal congestion, runny nose, sore throat, cough, fever, and headache, among others, which can affect the body's comfort and daily life.
A cold is a self-limiting illness that usually resolves on its own within a week or so. However, for the elderly, children, pregnant women, and people who are physically weak, the recovery period may be longer and require more rest and care. In addition, if the complications of a cold are severe, such as pneumonia, heart disease, etc., the recovery period will also be extended.
Although a cold is not a serious illness, it can affect the body's immune system and make people more susceptible to other diseases. In addition, colds can also affect people's mental state, leading to mood problems such as low mood, irritability, anxiety, and depression. Therefore, it is very important to prevent colds.

People who don't catch a cold for a long time have poor immunity?
Does people who have not had a cold for a long time mean that their immunity is relatively poor? This is a common question, but it is not entirely true. Colds are caused by viruses, and there are many types of viruses, and whether the human body becomes ill after exposure to the virus or not depends largely on the immunity of the individual.
First of all, we need to understand that immunity refers to the body's ability to resist foreign pathogens. It is done by the immune system, including organs such as lymph nodes, bone marrow, spleen, and various immune cells and molecules. When the body is exposed to the virus, the immune system responds quickly by producing antibodies to fight the virus.
Sometimes, however, even if a person has been exposed to a virus, it does not necessarily become ill. This is because the body's immunity plays a key role in the fight against the virus. If a person has a strong immune system, they may not get sick even if they are exposed to the virus, or even if they do, the symptoms will be mild.
So, does a long-term absence of a cold mean that they have a poor immunity? Not necessarily. Sometimes, the human body may have strong immunity due to some reason (such as genetic factors, lifestyle, dietary Xi, etc.), so it rarely catches a cold or never catches a cold. In addition, the body's immune system is a complex network, and sometimes cold viruses may not have a chance to invade the body or be quickly eliminated by the body, so not having a cold does not necessarily mean that the immunity is poor.

People who have not caught a cold for a long time are not only weak in immunity, but also prone to cancer?
In our daily life, some people do not catch a cold for a long time, which is often seen as a sign of good health and strong immunity. Recently, however, there has been a claim that people who have not had a cold for a long time are more likely to get cancer. Is this true? Let's find out.
First, we need to understand the link between colds and cancer. A cold is actually a reaction of the body's immune system to an alien virus. When our body is attacked by a cold virus, the immune system responds quickly and releases a large number of immune cells and antibodies to fight the virus. This process can help our body better adapt and resist various diseases and viruses.
Cancer, on the other hand, is a disease caused by abnormal cell growth. These abnormally grown cells can grow uncontrollably and may form tumors. Although a cold itself does not directly cause cancer, people who do not have a cold for a long time may deprive the body of some opportunities to fight the disease, making the immune system relatively weak. This means that their bodies may be more susceptible to other diseases, including cancer.
In addition, some studies have shown that people who have frequent colds may develop stronger immunity and thus better fight the onset of cancer. This is because cold viruses and other viruses, when they attack the body, can help stimulate the body's immune response, which produces more immune cells and antibodies. These immune cells and antibodies can fight not only cold viruses but also other viruses and bacteria, including cancer.
In summary, people who have not had a cold for a long time are not necessarily more likely to get cancer, and there is no direct causal relationship between colds and cancer, however, maintaining a moderate cold can stimulate the body's immune response, which can help the body better fight off various diseases and viruses, including cancer. Therefore, you should focus on maintaining a healthy lifestyle and strengthening your own immunity, so as to better protect your physical health.
