Walking for an hour a day The American magazine Reader’s Digest has told that a 30-minute walk after meals every day, or four hours a week, can cut the risk of pancreatic cancer in half. A long-term study of 70,000 people at the Harvard School of Public Health also found that walking for just one hour a day can reduce the chances of developing colorectal cancer by half. This is because pancreatic cancer is related to high body heat, walking can burn calories, which can directly prevent pancreatic cancer. In addition, sweating after exercise can make the body of lead, strontium and other carcinogens with sweat out of the body, thus playing a role in cancer prevention. Shandong Academy of Medical Sciences Affiliated Hospital Medical Oncology Han Chunyan drink 6 glasses of water every day One of the most authoritative medical journals in the world, “The New England Journal of Medicine” research shows that men who drink 6 glasses of water a day (240 grams per glass) will reduce the risk of bladder cancer by half, and the risk of women suffering from colon cancer will be reduced by 45%. This is because drinking water can increase the frequency of urination and defecation, and get rid of harmful substances in them that may irritate the bladder mucosa and colon, such as urea and uric acid. However, people over 40 years of age it is best to check the colonoscopy every two or three years, if there are polyps, early detection can reduce its chance of cancer. Eat with onions and garlic In China, the province with the lowest incidence of stomach cancer is Shandong, a large province of onion and garlic cultivation. In the four counties north of the Yangtze River with the lowest mortality rate of stomach cancer, the first is Cangshan County, Shandong, where per capita will eat 6 kilograms of garlic every year. This is related to the fact that allicin has an antioxidant effect, which can reduce the content of carcinogen nitrite in the human body. Some studies have shown that people who eat more garlic have a 60% lower risk of stomach cancer. Garlic can only produce allicin when it is crushed and fully combined with oxygen, and it is very unstable and will lose its effect once it is exposed to heat. Therefore, it is best to crush garlic and eat it raw, or mince it and put it in coleslaw. 15 minutes of sun exposure In the cheapest cancer prevention prescription, sun exposure is considered to be the ultimate, without any cost, can increase the body’s vitamin D content to play a role in preventing cancer. Experts say that insufficient vitamin D increases the risk of breast, colon, prostate, ovarian and stomach cancers. To avoid the increased risk of skin cancer from exposure to the sun, just 15 minutes of sun exposure a day is enough. Four cups of green tea a day The tea-loving Japanese have spent nine years doing a survey, and found that as long as you drink four or five cups of tea a day, you can reduce the risk of cancer by 40%. Relevant experts on the cancer prevention role of tea has 17 years of research, found that oolong tea, green tea, black tea on oral cancer, lung cancer, esophageal cancer, liver cancer and so on have a good preventive effect. Among them, green tea, including Longjing, Biluochun and Maofeng, has the most significant effect, with five times more cancer-preventing ingredients than other teas. However, it is best not to drink tea that is too strong and too hot, otherwise it will affect its anti-cancer effect. The best drinking temperature should be about 60 degrees Celsius, tea steeped for 5 minutes, the active ingredients can be dissolved in the water. At least open the window for half an hour Few people know that, in addition to formaldehyde, there is a very strong carcinogenic gas – radon and its substrate. It is generally hidden in granite, cement, tiles, along the cracks in these places to diffuse into the room, through the respiratory tract into the human body, over time, will induce lung cancer. In fact, as long as the windows are opened for half an hour every day, the concentration of radon can be reduced to the same level as outdoors. In addition, radon will also be produced after the combustion of natural gas, so when boiling water in the kitchen, it is best to open the window and close the door connecting with the living room. Rub your back with a dry towel Japan had a craze of rubbing your back with a dry towel. Professor Mizuno, vice president of the University of Tokyo, pointed out that this can play a role in preventing cancer, because friction and heat will activate a kind of cell in the subcutaneous muscle tissue of the back, which can play a role in eroding and destroying cancer cells. For middle-aged and elderly people, whether rubbing, rubbing or scratching the back is a good health care method. Or use the ends of a dry towel, straight and horizontal repeatedly rubbing the whole back for about 10 minutes, until the skin is red and hot. A mouthful of rice chewing 30 times Peng Yifan told reporters, a survey proved that eating old gulping people, the chances of stomach cancer is higher. And more chewing can reduce the burden of food on the digestive tract, reduce the risk of gastrointestinal cancer. In addition, the United States, the University of Georgia experiments found that saliva has a very strong “anti-drug” effect, can make the culprit of liver cancer aflatoxin toxicity, almost completely disappeared in 30 seconds. Therefore, according to a second chewing to calculate, a mouthful of rice is best to chew 30 times, only with cancer prevention. Sleep enough 7 hours The American Institute for Cancer Research survey found that women who sleep less than 7 hours a night have a 47% higher chance of developing breast cancer. This is because sleep produces a kind of melatonin, which slows down the production of estrogen in women’s bodies and thus serves the purpose of inhibiting breast cancer. It is best to start washing before 10:30 p.m. to prepare for bedtime, ensure that you go to sleep before 11:00 p.m., and get up at 6-7:00 a.m. In addition, German sleep experts pointed out that 1:00 noon is a person in the daytime a clear sleep peak, this time to take a nap, but also can enhance the body’s immune cells active, play a certain role in cancer prevention.
