I am a person with extremely low immunity, but it's unbelievable that I have become a doctor like this
Xiaoqiu is a doctor. During the COVID-19 outbreak in Guangzhou, she followed the hospital staff to various communities for nucleic acid testing, using her strong willpower to defend against the epidemic, just as she has always stood in the face of low immunity since childhood.
In Xiaoqiu's memory, she has been a frequent visitor to the hospital since elementary school. When I was in elementary school, I often caught a cold and had a high fever. Several times, it even turned into pneumonia.
In junior high school, she still frequently caught colds, usually two or three times a month. When she caught a cold, she coughed until her throat was sore, she couldn't speak, and she coughed until blood came out. Not only was she afraid, but even her classmates and teachers were worried about her. They always thought she was a paper person, unable to withstand the wind or rain.
In high school, although the frequency of colds decreased, the problem of easy diarrhea came knocking on my door. Because high school is far away from home, we need to live on campus and eat in the hospital cafeteria. For this reason, Xiaoqiu must go to the cafeteria to eat with a pinch, because once the food gets cold, she will definitely have diarrhea if she eats it. When eating, you have to be selective. You can't eat greasy, spicy, or too salty food, otherwise you'll have diarrhea again. The doctor said it's called irritable bowel syndrome.
Xiaoqiu University chose a medical major with the intention of taking care of her body. Having truly embarked on this path and witnessed countless cases of illness, she discovered that there are actually many people in the world who share the same suffering as her, as well as many who are stronger than her. From them, Xiaoqiu gained more courage to face life and the future. Although on the path of studying medicine, the problem of low immunity always arises and increases obstacles, such as itching when touched with a potion, she is no longer afraid.
1、 The best doctor in the world is not an apple, but an immune system
As the saying goes, "An apple a day keeps the doctor away from me," but the correct answer should be "With immunity in hand, the doctor stays away from me
We often hear the term immunity, which is enough to demonstrate its importance to us, but our understanding of it is very limited.
Immunity is as important to the body as the military is to multiple countries, as it can help the body resist diseases. When bacteria enter the body, the immune system recognizes them and commands white blood cells and lymphocytes to fight each other and engulf the bacteria; When the cells of the body age and die in metabolism, the immune system can recognize them and then engulf them, making space for newly born cells; When genetic changes occur in the body's cells, the immune system also recognizes them and eliminates them to prevent them from transforming into cancer cells.
Although the function of immunity is strong, it is not necessarily better with higher immunity. Low or high immunity is a manifestation of immune dysfunction and can have adverse effects. For example, a high immune system can easily trigger autoimmune diseases such as asthma and skin allergies, and may also fail to recognize normal cells and mutant cells, leading to the mistaken clearance of normal cells.
Therefore, we cannot blindly pursue high immunity, but rather maintain it at a normal level. However, regardless, as one ages, the body's immune system will undergo a decline.
2、 After the age of 40, the immune system is most fragile
The immune system of the human body varies and changes with age.
Professor Wang Yuedan from the Department of Immunology at Peking University School of Basic Medical Sciences stated that the human immune system begins to decline at the age of 30, with the weakest point occurring at 40. Due to the high pressure of life and work in middle age, bad habits such as staying up late, irregular diet, and lack of exercise developed in youth are difficult to correct. Continuing to squander revolutionary capital ultimately leads to immune system problems.
The problem of low immunity can be reflected in the level of physical health, causing mental and physiological problems in people.
3、 Low immunity can cause four major symptoms in the body
So, what symptoms does a weakened immune system cause in the body?
Firstly, people with weakened immune systems will always feel tired. When doing the same work tasks as others, they will still be energetic after others have completed them, while you will feel sluggish, as if this task has emptied your body.
The human gut is the main site for the distribution of the immune system. When the immune system is low, intestinal diseases such as indigestion and diarrhea naturally occur, so people with low immunity often have many intestinal diseases.
Secondly, when the immune system is weakened, the resistance to the invasion of viruses or external pathogens becomes weaker, making it easier to catch a cold.
Diseases enter through the mouth, and the food we eat passes through the mouth. If certain pathogens are mixed in, the mouth may be affected. If there are still bad habits of smoking and drinking alcohol, the probability of developing oral ulcers will greatly increase in the case of low immunity.
If the above four situations frequently occur, then it is important to pay attention to improving immunity. Here are four suggestions for improving immunity.
4、 How to enhance immunity
Improving immunity requires starting from four aspects: diet, exercise, sleep, and mental health.
Firstly, maintain a balanced nutrition, avoid picky or biased eating, provide sufficient nutrients for the production of immune cells and molecules, and consume foods high in protein, vitamin C, vitamin A, vitamin E, iron, zinc, and selenium.
Secondly, exercise regularly. Persist in doing 30-45 minutes of heart rate boosting exercise (such as taking a walk after dinner) for 5 days a week. After 12 weeks, the number of immune cells will increase and the immune system will be enhanced.
Thirdly, ensure adequate sleep. Researchers have pointed out that people who ensure eight hours of sleep have 50% more flu antibodies than those who only sleep four hours.
Fourth, reduce stress. When stress comes, it can be relieved in a timely manner by doing exercise, singing, or talking to someone to avoid negative emotions affecting the secretion of glucocorticoids and other hormones, which can have a negative impact on the immune system.
People with weakened immunity are more susceptible to diseases, but the higher the immunity, the better. It is important to maintain a balanced state. Immunity is the body's army that resists foreign invasion and cellular "betrayal". By adjusting diet, exercise, sleep, and mental state, this army will become stronger and stronger.
