The advantages and disadvantages of eating snacks at night may satisfy the temporary hunger, but it is actually quite harmful.
Hazard 1: The peak of calcium excretion is usually 4-5 hours after eating. If you eat dinner too late, when the peak of calcium excretion comes, people have gone to bed and fallen asleep, and urine will remain in the urinary tract such as ureter, bladder and urethra, which can't be excreted in time, resulting in increasing calcium in urine and easy to deposit and form small crystals. Over time, it will gradually expand and form stones.
Hazard 2: I often like to eat supper. If I eat high-fat and high-protein food, it is easy to make the blood lipid in the human body suddenly rise. Human blood always keeps a high fat content at night. Eating too much at night, or eating frequently and repeatedly, will lead to a significant increase in blood cholesterol synthesized by the liver.
The worst thing is that the biological clock is out of order, which is even more harmful.
I drink beer every night. What are the disadvantages in the long run? The most obvious is the beer belly after a long time.
Because you drink at night
Therefore, it will cause alcohol to affect the stomach for a long time.
Cause some stomach problems
In addition, it will increase the risk of high blood pressure.
Disadvantages of eating snacks in class Many people are asking about the disadvantages of eating snacks. Give children snacks. Appropriate snacks are necessary and beneficial to children's health. However, it is harmful for adults to like to eat snacks. This is because snacks will not only increase the burden on the stomach, but also lead to excessive energy, especially chocolate and ice cream with high calorie and high protein. This is one of the main reasons for the obesity of office workers.
In addition, eating snacks without restraint, especially before going to bed, will affect oral hygiene and increase the probability of dental caries, which is an unscientific eating habit and affects health. When tea is used for drinks, the main component of sugary drinks is sucrose. Although sugar is an important nutrient necessary for human life activities, the intake of sugar is not as high as possible. Office workers have less activities and less energy consumption. Excessive intake of sugar makes it difficult for people with high blood sugar to control their blood sugar levels. Obese people are particularly sensitive to sucrose, which is quickly digested and absorbed after ingestion and converted into fat to accumulate in the body. The younger the obesity age, the longer the obesity history, and the greater the risk of diabetes, hypertension, coronary heart disease and hyperlipidemia in later life. Excessive intake of high-sugar drinks will consume a lot of vitamin b 1 to accelerate the decomposition of sugar. If vitamin b 1 is insufficient, it will affect the excretion of metabolites such as pyruvate and lactic acid. Once these metabolites accumulate too much in brain tissue, people will be grumpy, emotionally unstable, and have abnormal reactions such as anger and excitement. Therefore, sugary drinks should not be used as drinking water or tea.
Eating snacks also has disadvantages, such as working and studying late at night and consuming a lot of energy. There is nothing wrong with adding a snack before going to bed. The key is appropriateness. The right dinner has been measured. For example, manual workers in the middle and night shifts should eat more food, and the dishes are mainly light and digestible food. As for mental workers, it is generally better to drink a glass of milk and eat 4-5 soda cookies before going to bed. Never eat big fish and meat, or the pancreas in the human body will secrete a lot of pancreatic juice and try to digest food. The secretion of pancreatic juice suddenly increases, especially in patients with chronic pancreatitis (mild symptoms are generally unknown to them). Due to the increase of pressure in the pancreatic duct, pancreatic tubules and pancreatic cells rupture and pancreatic juice overflows. At the same time, there is duodenal edema, and the passage of bile into the intestinal cavity is blocked, so that bile overflows into the pancreatic duct, activating pancreatin, causing acute pancreatitis and even sudden death. Therefore, the diet should be moderate, especially for patients with chronic cholecystitis, gallstones and chronic pancreatitis.
In addition, chronic diseases such as obesity, hyperlipidemia, hypertension, hyperglycemia, hyperuricemia and coronary heart disease are also one of the causes that cannot be ignored. You see, eating snacks has many disadvantages, so pay attention! It's better to eat less snacks.
What are the disadvantages of surfing the Internet for a long time? Everything has two sides, so does surfing the Internet. There are both disadvantages and advantages. The key is to see how you handle it. Disadvantages: chatting and playing games for a long time will not only affect people's normal study, work and life, but also affect people's health. Benefits: Through the Internet, we can learn a lot, get more help, get friendship, even work and money, but it won't take long. Electromagnetic radiation will affect our health (especially leukemia).
Electromagnetic radiation usually produces biological effects on the body through thermal effect, non-thermal effect and * * *. Excessive fever and long-term exposure to radiation will do harm to human body. The damage degree is directly proportional to the cumulative radiation dose and exposure time, and inversely proportional to the distance. The damage effect on different groups of people is different. Women, children and the elderly are all sensitive groups, especially the fetus. According to experts, there are six main hazards of computer radiation. First, it is probably one of the causes of childhood leukemia. Second, it can induce cancer and accelerate the proliferation of cancer cells in the human body. Thirdly, it affects the human reproductive system, which is mainly manifested in the decline of male sexual ability, spontaneous abortion of pregnant women and fetal malformation. Fourth, it will lead to mental disability of children. Five, affect people's cardiovascular system, manifested as palpitations, insomnia, menstrual disorder in some women, bradycardia, decreased cardiac blood volume, accelerated sinus heart rate, leukopenia, decreased immune function, etc. Sixth, it has a bad influence on people's visual system. In fact, computer radiation is not as terrible as people say. As long as the computer is used reasonably, the harm of radiation can be minimized, and even if you are in front of the computer for a long time, you will feel tired. 1. Keeping a certain distance from the computer is one of the important measures to prevent electromagnetic radiation. Because the intensity of electromagnetic radiation decreases with the square of the distance from the radiation source. The location of the computer is very important. Try not to let the back of the screen face people, because the back of the computer has the strongest radiation, followed by the left and right sides, and the front of the screen has the weakest radiation. Experts suggest that computer users should keep a distance of not less than 50 cm from the display screen and not less than 120 cm from the sides and back of the computer. The computer used in the office should be kept at the required distance. It is important to reduce the time of computer contact. Because the cumulative dose of radiation is proportional to the radiation intensity and radiation time, it is necessary to reduce the computer time. Because of the need of work, it is best not to spend more than 8 hours on the computer every day, and it is best to go outdoors every hour or two. 3. Don't put metal objects indoors, so as to avoid electromagnetic wave emission again. The room should be ventilated and transparent, and plants such as fairy heads can also be placed. It is said that it has the function of calming the air and preventing radiation. 4. When operating a computer, it is best to install a computer-specific color filter on the display screen to reduce the harm of radiation. When using a computer, you need to adjust the brightness of the screen. Generally speaking, the greater the brightness of the screen, the stronger the electromagnetic radiation, and vice versa, but it should not be too dark, so as not to affect the effect because the brightness is too small, and it is easy to cause eye fatigue. You should try to buy a new computer, and generally don't use an old one. The radiation of old computers is generally severe, which is generally 1-2 times that of new computers at the same distance and similar models. 5. Some people spend a long time online without interruption. In this case, the best way is to wear protective clothing and protective cap to directly reduce the body's absorption of radiation. Pay attention to eat carrots, bean sprouts, tomatoes, lean meat, animal liver and other foods rich in vitamins A, C and protein, and often drink some green tea. Green tea can not only eliminate the harm of computer radiation, but also protect and improve vision. If you are not used to drinking green tea, chrysanthemum tea can also play a role in resisting computer radiation and regulating body functions. Pay attention to do more outdoor sports. Cream can be applied to face and hands, and eye exercises or eye drops can be used for dry eyes. 6. Where there is electricity, there is radiation more or less, and LCD also has radiation, but around the screen, the radiation is small, and it is not as big as CRT of desktop computer. You can buy a laptop or desktop computer with an LCD monitor. Attachment: computer radiation 1, keyboard 1000 V/m 2, mouse 450 V/m 3, CRT screen 2 18 V/m 4, host 170 V/m electromagnetic radiation is divided into two grades, in which the power frequency band unit is μT, 0.4 μ.
People sleep for a long time a day, what are the disadvantages? "Some people divide the daily time into' March 8', that is, eight hours of work, eight hours of sleep and eight hours of other personal activities." Experts say that what ordinary people often say is "eight hours of adequate sleep".
"Why advocate eight hours instead of ten hours? This is all based on science. Sleep time can not be less or more. " According to experts from the combination of sleeping and relieving depression, it is clinically proved that excessive rest is not good for the human body. "The human body has a biological clock. The human body needs to relax and rest at some time, but it needs to be active at other times." Sleeping too long obviously reduces physical exercise. "It may also cause symptoms such as diabetes and obesity for a long time."
Will you always want to eat snacks after quitting smoking for a long time? Yes, you can eat melon seeds or chewing gum when you quit smoking, and you can also exercise your facial muscles by chewing.
What harm does it do for women to add quilts to find * * * for a long time? As long as they don't * * * frequently, there is no harm. If they do this every day, even the best bodies will collapse. It doesn't matter twice a week, just pay attention to hygiene.
