Mr. Li is a department manager of a foreign company, absolutely urban white-collar, with a house and car, a monthly income of more than 10,000 yuan, but busy work, overtime is a common occurrence. Two days ago suddenly fever, I gave him a routine physical examination and related laboratory tests, told him that he had a “viral upper whistle infection”, which is often referred to as “viral flu”. I gave him some vitamin C, detoxification of Chinese medicine with a three-day leave of absence, and told him to drink more water and rest. He begged me if I could prescribe him some “good medicine” so that he could get better faster and not miss work, because he was too busy at work. This is another “workaholic” who has to carry a leave slip to work. This situation is often encountered by the author when dealing with patients in the outpatient clinic, and the “planned economy era” of the “bubble sick leave” is the opposite, now grinding the doctor to ask for a leave of absence of the patient is rare, and the doctor according to the needs of the patient rest, but often met The reason for “refusal” is simply that they are too busy with work, or study tasks, time constraints, of course, there are also a few private sector employees have “leave may ‘lose their jobs'” concerns. The reason for not wanting to take sick leave is also worth understanding and sympathizing with, but the harm is obvious. In the case of Mr. Li, the reason why he got sick is because of viral infection, and viral infection is not something that can be fought by antibacterial drugs such as “so-and-so floxacin” and “so-and-so celine”. The good thing is that most viral infections, even including the SARS that ravaged the capital in the previous period, are self-limiting, in other words, they can heal on their own. The process of self-healing is the process by which the body’s immune cells recognize the virus, proliferate effectively, and clear the virus. Since our body has the ability to clear the virus, all we have to do is to help it, that is, to improve the body’s immune system, and rest is the best way to achieve this purpose. The folk saying “three parts cure, seven parts nourishment.” This is also the truth. Rest is so important for the recovery of “cold” and for other diseases as well. We all have the experience that there are often triggers to get sick, these triggers are often fatigue, mental tension, emotional depression, emotional trauma, etc. It is these triggers that make our immune system function is reduced, so “relaxed to the invaders of the vigilance” or “to the internal troublemakers The first situation makes the body’s gateway to the immune system to be more open to the public. In the second case, individual abnormal cells escape from the immune surveillance and keep proliferating, which eventually leads to the occurrence of tumors; in the third case, the normal tissues of the body are self-destructed and lose their functions, which are autoimmune diseases, such as rheumatoid arthritis and systemic lupus erythematosus. The internal cause of the disease is the abnormal immunity, and rest can restore the immunity, for reversible diseases such as viral infections can shorten the course of the disease, for progressive diseases such as tumors can slow down their development, so rest is an important “treatment measures”. Of course, adequate rest can also prevent the occurrence of disease. On the contrary, if you do not get proper rest, it may lead to prolongation of the disease, or it may lead to aggravation or even irreversibility. Some people have chronic hepatitis B, and the speed of hepatitis B virus replication and the size of the body’s immunity is related, if not properly rested, immunity is low, hepatitis B virus will be replicated in large quantities, the resulting liver damage will continue to aggravate, and eventually lead to liver sclerosis or even liver cancer. Many women have suffered from urinary tract infections, some even acute pyelonephritis, in addition to the selection of sensitive antibacterial drug treatment, rest is important, if not sufficient rest, antibacterial treatment is less effective, so that the disease is prolonged, repeated attacks and turned into chronic pyelonephritis, when the kidney damage becomes irreversible, eventually leading to kidney failure, the continuation of life depends on dialysis or kidney transplantation. Patients suffering from infectious diseases, leave is not only conducive to their own recovery, but also to the protection of the surrounding susceptible people, which is essential. In short, “carrying a sick note to work” is not an uncommon phenomenon, I hope that those who read this article can accept my “advice”, because health is the most important.
