I. Three major causes of cancer caused by lifestyle “Cancer incidence status and disease types are different in different places, which means it has a great relationship with the environment”. According to the nature of environmental pollution, there are 3 major categories: chemical, physical and biological, among which chemical factors are the main ones. Due to the popularity of computers and cell phones, people are exposed to more radiation, and some minerals, stone necklaces, home decoration materials, etc. all contain cancer-causing factors. In short, environmental pollution, long time exposure to radiation and changes in people’s diet structure are the three major causes of cancer in lifestyle. Bad lifestyle and cancer Some cancers are closely related to lifestyle, so they are also called “lifestyle cancer”. “Abnormal eating habits and structure as well as improper lifestyle are important enemies of our health”. In modern society, eating out has become a common practice for various reasons, and most of the food is high in fat and calories, while the intake of vitamins and dietary fiber is very small. The change of diet structure has greatly increased the incidence of cancer. Barbecued and smoked foods, fried foods, moldy foods and pickled foods all contain cancer-causing ingredients. In addition, as people’s night life is getting richer and richer in recent years, staying up late and returning home at night are common. Sleeping late directly affects the normal metabolism and blood production and detoxification of human body, which will lead to insufficient blood energy and accumulation of toxins in the body over time. Malignant tumors are prone to the elderly in the past, but nowadays, they have shown younger characteristics. Moreover, the structure of malignant tumors has changed. As most women marry late and have children late, resulting in hormonal changes in the body, the incidence of breast cancer has increased significantly, which poses a serious danger to women’s life and health. Some data show that the mortality rate of urban malignant tumors is significantly higher than that of rural areas, and some cancers are even directly proportional to economic income and education. Cultivate healthy habits 1. Eat a good breakfast. There is a saying that “eat a good breakfast, eat a full lunch, eat less dinner”, but due to the time constraint in the morning, some people are too late to eat breakfast. Long-term hazards of not eating breakfast are the following: (1) the human immune system decline: this is the reason why people who do not eat breakfast for a long time are prone to various chronic diseases. Stomach for a long time in a hungry state, easy to cause gastritis, gastric ulcers, and these stomach diseases are precancerous lesions of stomach cancer; breakfast is not enough, lunch will be hungry and a lot of food caused by the burden on the digestive system, easy to induce gastrointestinal diseases; do not eat breakfast will make the platelets in the blood easier to stick together, thereby increasing the chances of heart disease. (2) Easy to get fat: people who eat high-calorie breakfast tend to have low-calorie lunch and dinner or omit to eat; while people who simply make do with breakfast tend to have rich and high-calorie lunch and dinner. Comparative studies show that although these two types of people consume the same amount of calories a day, the fat oxidation is different. People who eat high-calorie foods for breakfast, together with low-calorie lunch and dinner meals, are less likely to accumulate fat, while people who do not eat breakfast or eat too simply are unable to provide enough calories and nutrients. (3) Risk of hypoglycemia if you don’t eat breakfast: The normal blood sugar level in fasting is 80~120mg/100ml. if the blood sugar level is too low, you will feel hungry and tired, and even dizziness, unsteadiness or palpitations. The maintenance of blood glucose level in the body mainly depends on the type and quantity of the first meal eaten in a day. Without breakfast, it is difficult to maintain the normal blood sugar level in the body, there will be hypoglycemia, there is not enough blood sugar in the body for consumption, the body will feel tired, fatigue, irritability, irritability, slow reaction, directly affecting the work, study and body, serious cases can be deficient, hypoglycemia, coma, etc.. The United States nutritionist survey shows that many car accidents have occurred with the perpetrators of low blood sugar levels, unresponsiveness. (4) do not eat breakfast to grow old faster: breakfast provides energy and nutrients in the whole day energy and nutrient intake occupies an important position, do not eat breakfast or breakfast quality is not good, the body only have to use the body’s stored glycogen and protein, over time, will lead to dry skin, wrinkles, anemia, etc., accelerate the aging of the body, and in serious cases will also cause nutritional deficiencies. In addition, experts have summarized the consequences of long-term skipping breakfast: men do not eat breakfast, liver problems; women do not eat breakfast, the uterus will have problems. Nutritionists for us with a reasonable nutritious breakfast for reference only: first of all, a reasonable breakfast food should be rich in water and nutrition.

In the night sleep, the body will secrete a large number of “melatonin”, which is a kind of sympathetic excitation can inhibit the human body, so that blood pressure drops, heart rate slows down, the heart gets rest, immune function is strengthened substances. But this substance is not allowed to see the light source, or it will immediately stop secretion. So sleep, should try to adjust the room light to the darkest, to ensure that the brain can secrete enough melatonin to maintain the normal needs of the body. And be sure to seize the night, the golden hour of sleep, to ensure that there is sufficient, high-quality sleep time. In addition, the human body contains “T cells” involved in immune function, the number of which is also related to whether there is sufficient sleep. But a good night’s sleep is not a lot of sleep, as long as you wake up in the morning feeling refreshed, you can be considered to have achieved a high quality sleep. It is important to develop a good habit of going to bed early and waking up early. Early to bed is to seize the best sleep time, early to get up is to leave yourself some exercise time.

The so-called aerobic exercise refers to brisk walking, cycling, rope skipping, mountain climbing, swimming, yoga, etc. Exercise 3 times a week, each exercise to reach 110 to 130 beats per minute and last 30 minutes, you can play a fitness role. However, because each exercise, muscle tissue will appear some slight tear, the immune system needs to consume energy to repair it, so if you exercise too much, it will increase the burden on the immune system, not only affect the effect of exercise, but also prone to respiratory tract infection symptoms. 4, abandon the bad habits of life. One is not hygienic, life through the habits; two is into the night playing mahjong habits; three is the problem of irregular meals; four is the painting country wine addiction to tobacco.
