Li Jia is a 57-year-old retired worker, in order to maintain her figure and health, she decided to start running exercises, at first, Li Jia insisted on running 5 kilometers every morning, gradually, she ran farther and farther, and even later ran more than 10 kilometers almost every day.
About three months later, Li Jia began to feel abdominal discomfort, with diarrhea, abdominal pain and other symptoms.
At first, she thought it was just ordinary gastroenteritis, but it didn't get better after taking medicine, and the painful Li Jia had to go to the hospital for examination, and the doctor suggested that she do a colonoscopy, and the results surprised Li Jia, she was diagnosed with advanced colon cancer.
Li Jia couldn't accept this fact, she asked the doctor: "I usually eat a healthy diet, and I insist on running and exercising every day, how can I get colon cancer?"
The doctor sighed and said: "Excessive exercise will damage the body's health, strenuous exercise will lead to intestinal ischemia and hypoxia, long-term so easy to induce intestinal diseases, and even develop colon cancer in severe cases, many people blindly pursue extreme sports such as marathons, in fact, the risk is very high, moderate exercise is the king." "
Li Jia regretted it too much, and she realized the dangers of excessive exercise, but it was too late, and a few months later, Li Jia died of colon cancer.
Li Jia's experience is a wake-up call that excessive exercise is not a healthy way to health, and while moderate exercise is good for health, strenuous exercise may be counterproductive.
Many people think that the longer and more intense the exercise, the better it is for the body, but in fact, excessive exercise will not only not bring additional health dividends to the body, but will become an invisible killer of health.
From a medical point of view, moderate exercise can improve cardiopulmonary function, enhance immunity, and reduce the risk of chronic diseases, but excessive exercise may cause damage to the cardiovascular system, digestive system, etc., and induce a variety of diseases.
Taking long-distance running as an example, some studies have found that people who engage in high-intensity endurance sports such as marathons for a long time have a significantly higher risk of colon cancer than the general population.
This is because prolonged strenuous exercise can lead to intestinal ischemia and hypoxia, damaging the intestinal mucosal barrier, which increases the risk of colon cancer.
In addition to the digestive system, excessive exercise may also damage multiple systems such as cardiovascular, bone, endocrine, etc., strenuous exercise will increase the myocardial oxygen consumption sharply, which can lead to myocardial damage in the long run, increase the risk of cardiomyopathy, sudden death and so on.
In addition, excessive exercise will also accelerate the wear and tear of bones and joints, causing bone problems such as osteoporosis and arthritis, and at the same time, excessive exercise may also disrupt the body's endocrine rhythm and lead to endocrine disorders.
So, what is excessive exercise? Simply put, it means exercising more intensely and for more time than the body can handle. Specifically, there are the following criteria:
1. Exercising for too long, such as more than 1 hour at a time.
2. The exercise intensity is too high, and the heart rate exceeds 85% of the maximum heart rate for a long time.
3. Exercise too often, more than 5 times a week.
4. Blindly pursue high intensity, without considering your own conditions.
5. Exercise while sick or tired.
Excessive exercise can not only lead to colon cancer, but also may cause a series of problems such as myocardial damage, bone and joint damage, endocrine disorders, and decreased immunity.
For colon cancer prevention, in addition to avoiding excessive exercise, pay attention to the following:
1. Eat a light diet and eat more high-fiber foods such as fruits, vegetables, and whole grains.
2. Eat less red meat and processed meat products.
3. Quit smoking and limit alcohol.
4. Regular screening, especially for high-risk groups (e.g., patients with inflammatory bowel disease, family history of bowel cancer, etc.).
For most people, 3-5 times a week of moderate-intensity aerobic exercise for about 30 minutes at a time, along with moderate strength training, is enough to maintain good health.
The so-called moderate-intensity exercise, which is the degree to which you feel a little wheezing but can still speak, such as walking, jogging, swimming, cycling, etc., are good aerobic exercise options.
When exercising, we should pay attention to step by step, do what we can, avoid blindly pursuing high intensity, and at the same time, fully consider our age, physique, health status and other factors, and choose the exercise method and intensity that suits you.
In addition to scientific exercise, the prevention of colon cancer also needs to pay attention to many aspects such as diet and life. In terms of diet, it is necessary to focus on light, eat more vegetables, fruits, whole grains and other foods rich in dietary fiber, eat less red meat, processed meat products and other high-fat, high-protein foods, and at the same time develop healthy living habits, do not smoke, and drink less alcohol.
For some high-risk groups, such as those with a family history of colorectal cancer and patients with ulcerative colitis, regular colonoscopy is also required to detect and treat precancerous lesions early.
Colon cancer is a high-incidence malignant tumor of the digestive tract, and the early symptoms are not obvious and easy to be ignored, but if it can be detected and treated early, the prognosis of colon cancer is still better.
Therefore, we should take the initiative to learn about colon cancer, understand its risk factors and preventive measures, develop healthy lifestyle habits, and have regular medical check-ups, so as to minimize the risk of the disease.
