Li Wei, 50 years old, is a sturdy middle school physical education teacher. Every day, he stands energetically on the playground, guiding the students to exercise, and his health and vitality are often envied. However, there is one thing that bothers Li Wei lately – he always seems to be unable to escape the flu.
This winter, Li Wei has caught a cold for the third time. Each cold seemed more uncomfortable than ever, and the persistent cough, sore throat and high fever forced him to take time off work to rest at home. He began to reflect on why he was so prone to illness as a person who exercised every day, and was it just because he was getting older?
Li Wei's daily life is actually very regular. He is a non-smoker, eats a balanced diet and gets enough sleep every day. At school, he was constantly exposed to different students, which also made him a high-risk contact for the flu virus. He began to realize that maybe not all flu was caused by bad Xi, and maybe he belonged to the kind of "susceptible constitution" that was particularly prone to flu.
Susceptibility constitution, as the name suggests, refers to those who are more sensitive to diseases, especially infectious diseases. The immune system of this group of people may not be as strong as it seems. They may be more susceptible to environmental changes or less resistant to certain viruses and bacteria. Li Wei began to reflect on whether it was some details of his own life that exacerbated this physique.
Medical experts point out that susceptibility is closely related to genetic factors, lifestyle Xi and environmental factors. For example, long-term mental stress, lack of sleep, unbalanced diet, etc., can weaken the immune system and make people more susceptible to the flu. In addition, for people like Li Wei, who work in crowded environments, frequent exposure to the virus also increases the risk of contracting the flu.
A striking study showed that people with good Xi habits had a 50% lower rate of flu infection than those with poor Xi habits. This underscores the importance of preventive measures in maintaining health. Li Wei began to realize that although his Xi seemed good, there was still room for improvement, especially in his work environment.
Through further counseling and self-education, Li Wei learned some new strategies to strengthen his immune system. He began to pay more attention to personal hygiene, such as washing his hands frequently and avoiding contact with his eyes, nose and mouth. At school, he encourages students to do the same and to keep classrooms as ventilated as possible.
First of all, Li Wei adjusted his diet Xi habits. On the advice of his doctor, he began to reduce his intake of high-sugar and high-fat foods and instead increased more vegetables and fruits. For example, his breakfast has changed from fried dough sticks and soy milk in the past to oatmeal porridge and fresh fruit. According to the Chinese Dietary Guidelines for Adults, such dietary adjustments are beneficial to enhance the function of the immune system and reduce the occurrence of diseases.
Secondly, Li Wei strengthened regular physical exercise. As a physical education teacher, he already had a certain amount of exercise, but on the advice of his doctor, he began to incorporate more aerobic exercises, such as jogging and swimming. Studies have shown that moderate aerobic exercise can improve the body's immunity and reduce the occurrence of respiratory diseases.
In addition, Li Wei also began to pay attention to getting enough sleep. He used to stay up late to prepare for classes and not get enough sleep. Now, he tries to get at least seven hours of sleep a night and tries to maintain a regular sleep schedule. Sleep is essential for the health of the immune system, and a lack of sleep can make a person more susceptible to the flu.
In this process of transformation, Li Wei faced many challenges. Changing his eating habits Xi especially difficult for him because he had a hard time resisting the temptation of traditional snacks. However, he gradually learned to replace unhealthy options with healthy snacks, such as nuts and fruits. This persistence has not only improved his eating Xi, but also improved his overall health.
After months of hard work, Li Wei clearly felt that his physical condition had improved. He no longer has colds as often as he used to, and he is in good health even during the winter months. This change gave Li Wei great confidence and satisfaction. He began to share his experience with those around him, encouraging them to also take care of their health and immunity.
