The first: sit down and do not want to move to work a day sitting, home in the sofa do not want to move. Do not think that the harm of sedentary only hurt the cervical spine, spine. U.S. studies show that sedentary people are 40%-50% more likely to suffer from colon cancer than those who exercise regularly, and men are also prone to prostate cancer. German experts pointed out that the number of human immune cells increases with the increase in activity, and sedentary people have fewer immune cells, greatly increasing the chances of cancer; Japanese medical doctors found that most patients with stomach cancer usually eat too much saturated sedentary. The second one: eating less fruits and vegetables. Eating large fish and meat is not enough, and eating less fruits and vegetables has become a common problem of modern people. Do not underestimate the harm caused by this habit. One is to eat by nature will cause obesity, recent research shows that obesity and breast cancer, prostate cancer and many other cancers related. Second, vegetables and fruits contain a lot of dietary fiber, which can promote intestinal peristalsis and take away harmful substances. Not eating vegetables and fruits will increase the risk of colon cancer. Thirdly, it leads to lack of vitamins. The third type: always do not go to the toilet Want to go to the bathroom, but too busy to go, or can not find a bathroom, can only be held in. One or two times is okay, a long time, it will be a problem. The body needs to eliminate objects containing hydrogen sulfide, fecal odor, cholesterol metabolites and other carcinogens, accumulated in the intestines for a long time, will be repeatedly absorbed, stimulating the intestinal mucosa. According to investigation, lack of time to defecate has become the main reason why many young people suffer from colorectal cancer. The fourth type: not sleeping at night Many people have to stay up late for work; others catch up with the fashion, soak in bars every day and become “party animals”. The British Scientific Cancer Research Center studied more than 1,000 cancer patients aged 30-50 around the world and found that 99.3% of them stayed up late all year round and rested only after midnight. Staying up late can cause disruption of the biological clock on the one hand, and on the other hand, nighttime lights can disrupt the formation of melatonin in the human body, which is an important part of protecting the body’s immune function, and the lack of which can easily bring leukemia, breast cancer, prostate cancer, etc. to the door. The fifth: always drink boiling water Many people like to brew a cup of kung fu tea at leisure, unbeknownst to them, the tea that is brewed now “while it is hot”, may lay a hidden danger for esophageal cancer. The reason is that boiling water can scald the mucous membrane of the esophagus and cause oral mucositis and esophagitis, which may lead to cancer after a long time. If you feel hot food or drink, don’t swallow it in a hurry. Food with fillings may not be hot outside and hot inside, so be especially careful when eating. Don’t use a straw to drink hot drinks.
