1, not sleeping can cause cancer.
In recent years, cancer has come to us, and many people around us have left us because of cancer, so it is imperative to prevent cancer now, but many small habits in life can also cause cancer. Do you know all this? Follow Bian Xiao quickly and see if sleeping at night will cause cancer. Is it true or not?
A good sleep needs a good environment, but some people don't like to turn off the lights when they sleep. Why? But do you know how harmful it is to leave the lights on when you sleep?
Medical experts have found that turning on the light while sleeping will inhibit the secretion of melatonin and reduce the immune function of the human body. The secretion of melatonin can inhibit the excitability of human sympathetic nerve, lower blood pressure, slow down the heartbeat, rest the heart, enhance human immunity, eliminate fatigue and even kill cancer cells. When you turn on the light to sleep, the secretion of melatonin will be inhibited, which will not only affect the quality of sleep, but also affect the immunity of the human body and even lead to illness.
Sleeping with the lights on is a bad habit, and its pathological essence is fear of darkness. Most of this horror of darkness began in childhood, because in childhood, we often heard stories about ghosts and gods. The background, content and characters of such stories often walk into the invisible darkness at night or at ordinary times to show vividness and mystery. Over time, people will be afraid of monsters and darkness together, forming a dependence on lights, leading to fear of turning off the lights to sleep, which is also one of the main reasons for turning off the lights to sleep.
Medical experts have found that turning on the light while sleeping will inhibit the secretion of melatonin and reduce the immune function of the human body. When people fall asleep at night, the brain will secrete melatonin, which will be secreted vigorously from midnight 1 1 to the early morning of the next day and stop after dawn. The secretion of melatonin can inhibit the excitability of human sympathetic nerve, lower blood pressure, slow down the heartbeat, rest the heart, enhance human immunity, eliminate fatigue and even kill cancer cells.
But if you turn on the light while sleeping, the secretion of melatonin will be inhibited, which will not only affect the quality of sleep, but also affect the immunity of the human body and even lead to illness. There is a little-known endocrine organ in the human brain called the pineal gland. It has been confirmed by scientific research that one of the functions of pineal gland is to secrete a large amount of melatonin when people fall asleep at night.
The secretion of melatonin can inhibit the excitability of human sympathetic nerve, lower blood pressure, slow down heart rate, make the heart breathe, enhance human immune function, restore fatigue and even kill cancer cells. But the pineal gland has a great feature that as soon as the eyeball sees the light source, melatonin will be inhibited and ordered to stop secreting.
I know that people's eyelids partially block the light source. If you sleep with an eye patch, your eyes will not be exposed to light at night, and even if you sleep with the lights on, it will not affect the secretion of melatonin. However, once the light is turned on and the night is frequent, the secretion of melatonin will be more or less inhibited, which will indirectly affect the human immune function.
Drinking more than 3 cups of coffee every day is easy to cause cancer.
Nowadays, coffee has become an indispensable fashion drink for young people, and there are more and more coffee shops. However, health experts advise those who like coffee not to drink too much coffee. Some studies have found that coffee increases the risk of pancreatic cancer. Therefore, 2 ~ 3 cups a day is appropriate, and more than 3 cups will do more harm than good.
A study by Harvard University in the United States found that people who drink coffee are more likely to develop bladder cancer, especially women. If you only drink half a cup of coffee or don't drink coffee every day, the risk of bladder cancer is 1, so the risk of bladder cancer in men is 1.3 1, and that in women is 2. 19. Japanese scientific research also shows that some male patients with gastric cancer like to drink coffee.
Why does coffee cause cancer? There are several speculations at present. One is that caffeine can induce tumors; On the other hand, it is believed that in the process of making coffee, substances similar to poppy are produced, which leads to carcinogens in coffee.
2. Precautions for drinking coffee
1, drinking coffee should not be excessive. Drinking coffee in moderation can refresh you, but drinking more coffee than you are used to will make you too excited and even nervous. Therefore, although coffee is good for the human body, don't drink too much, and it is advisable not to drink more than 2 cups a day.
2, drink coffee to master the time. It is best to drink coffee after breakfast and lunch, because it can promote the peristalsis of the stomach, help digestion and break down the high-calorie and high-fat food you eat, and will not stimulate the stomach like drinking coffee on an empty stomach. It is best not to drink coffee after dinner, so as not to affect sleep. If you want to stay up late by drinking coffee, you may unconsciously drink too much, which is not good for your health.
3, coffee with sugar should be appropriate. There are many reports that drinking coffee can help you lose weight, because caffeine in coffee can make people more excited, thus promoting the burning of calories and playing a role in losing weight. However, after trying the "coffee diet", many people find that they are not thin, but fat! In fact, this is because most people add a lot of coffee partners and sugar when drinking coffee, and both partners and sugar can bring a lot of energy, so the amount of calories that caffeine helps the body burn is somewhat insignificant. Therefore, in order to prevent excessive calorie intake, it is best to drink less sugar when drinking coffee.
3. How to fight cancer
There are many anti-cancer recipes. After knowing the relationship between your gastrointestinal function and nutrients, you can always spend some time making an anti-cancer recipe yourself.
Anti-cancer principle 1: avoid high-energy diet
A large number of data show that people who eat a high-energy diet (which can also be understood as overweight people) have a high risk of cancer. High-energy diet includes refined staple food, high-cholesterol diet, high-sugar diet and high-fat diet.
Of course, these terms are quite complicated. To put it simply, we are not advised to eat fat meat, less beef and mutton (red meat), less fried food, less sweet drinks and less alcohol. At the same time, eat more coarse grains, and eat more fat and protein through aquatic products (fish, shrimp, shellfish) or eggs.
Anti-cancer principle 2: cook by yourself
Then, we should try to reduce the intake of synthetic food, pickled food and food additives. Simply put, it is best to cook by yourself. If it really doesn't work, please order some freshly fried side dishes in the restaurant.
It is unhealthy to eat less snacks such as potato chips, ice cream and beef jerky, as well as instant noodles, quick-frozen food, semi-finished products and canned food.
Anti-cancer principle 3: fruits and vegetables, fruits and vegetables, fruits and vegetables!
Adequate dietary fiber intake and vitamin intake are very important, that is, to ensure a certain intake of fresh fruits and vegetables every day. If you are limited to eating enough, eat less meat if you can eat vegetables.
Anti-cancer principle 4: reducing energy intake is of great benefit.
It should be pointed out here that the intake of all nutrients is related to people's own weight, height and basal metabolic rate. If there is a risk of cancer, it is generally beneficial to reduce energy intake.
In other words, it would be better to eat less than before getting sick, but we only compare ourselves with the past, not others, because it is boring. Of course, if you lose weight, that's another matter. )
Another problem here is basal metabolic rate. Simply put, it's your muscle mass. The higher the proportion of muscle to body weight, the higher the general basal metabolic rate. When the basal metabolic rate is high, the calorie intake can be relaxed appropriately. If you eat a piece of fat today, consider jogging for 20 minutes at night.
Conclusion: Are you surprised after reading the above? I finally know why I have to turn off the lights at night, not only for my health, but also to avoid cancer. Be sure to pay attention in the future. In addition, Bian Xiao reminds everyone here to pay attention to the health of living habits at ordinary times. Healthy lifestyle can also prevent cancer!
4. What should I do to prevent cancer?
1, lung cancer screening.
Lung cancer is a malignant tumor with the highest morbidity and mortality in China, and it increases with age. Therefore, middle-aged and elderly people should be alert to the occurrence of lung cancer. In addition to routine physical examination, a very effective project of lung cancer screening is low-dose spiral ct thin-slice scanning, which is easier to find small lesions than chest film. High-risk groups should be examined regularly, including: long-term smoking, especially men over 50 years old; Immediate family members with lung cancer; There are carcinogenic factors in the working or living environment; Repeated chronic lung injuries, such as repeated infections and tuberculosis.
2. Screening of esophageal cancer and gastric cancer.
China accounts for about half of the cases of esophageal cancer in the world, so early screening of esophageal cancer and gastric cancer is very important. It is suggested that in areas with high incidence of esophageal cancer and gastric cancer (such as Henan, Hebei, Northeast China, Guangdong, etc.), people over 45 years old should undergo esophagoscopy and gastroscopy every year. 90% of early esophageal cancer can be cured.
3, colorectal cancer screening.
At present, the incidence of colorectal cancer in Beijing, Shanghai, Guangzhou and other big cities has risen to the second place in the incidence of malignant tumors. Obesity, habitual constipation and familial polyposis are high-risk groups of colorectal cancer, so we must check them regularly. At present, microscopic colonoscopy is very convenient and can be performed in a painless state. If early polypoid lesions are found, they should be removed under the microscope in time to prevent canceration. In addition, it should be reminded that the occurrence of early gastric cancer is closely related to Helicobacter pylori infection. If screening finds helicobacter pylori infection, we must actively treat it.
4. Breast cancer screening.
Breast cancer is the first female malignant tumor in China, accounting for about 16.8% of all female malignant tumors, and the incidence rate is high in some coastal cities and big cities. Because the curative effect of breast cancer is closely related to clinical stages, the earlier it is found, the better the therapeutic effect. Therefore, it is suggested that middle-aged and elderly women pay attention to breast cancer screening. Molybdenum target mammography has high specificity and sensitivity for breast cancer, with low X-ray irradiation dose and few side effects. It is the most mature method for screening early breast cancer at present. Therefore, it is recommended that all women over the age of 40 should have this check-up regularly.
5. Cervical cancer screening.
The most common gynecological tumors in China are cervical cancer, ovarian cancer and endometrial cancer. Among them, cervical cancer needs special attention from women.
It is suggested that young women who have been married for more than 1 year, or have a sexual history of more than two or three years, and middle-aged and elderly women, it is best to have cervical exfoliation cytology examination regularly. This examination is the simplest method for screening cervical cancer and precancerous lesions, and the operation is simple and painless. Brush off the exfoliated cells in the cervix with a small brush. At the same time, it is also recommended that women have regular gynecological examinations, such as pelvic B-ultrasound and related tumor markers. The combination of these methods can effectively screen almost all gynecological tumors. In addition, it should be reminded that women should pay attention to avoiding high-fat diet in their daily lives and lead an honest and clean life. Be alert to abnormal signals such as abnormal menstruation and postmenopausal bleeding.
