Getting up early can cure cancer, paralysis, gastric ulcer and myopia. In short, there are too many benefits. If you get up late, it will lead to dementia, numbness, Parkinson's disease and neuropathy, and later you will become a vegetable. People get up earlier every morning. If you get up early, you can do things more thoroughly. It is also good for the body and radiant, so it is called "three lights"; Getting up late and not having enough time will naturally make you careless, which is not good for your health. You panic every day, so you say "three panic" "Three" is an imaginary index here, which means "universality" and "regularity". Is it really good to get up early? The answer is yes. First of all, people who get up early and have fresh air and sleep in the house all night are relatively short of indoor oxygen because of breathing exercise all night. At this time, it is very necessary to have enough oxygen to supplement. There are inexhaustible oxygen sources in nature, and there is an intoxicating feeling of My Sweetie in the morning air, so you can enjoy it to your heart's content. Oxygen is sufficient, and the functions of the lungs, heart and brain are fully active, which is naturally beneficial to the body over time. Early morning is more precious to this city. At this time, the car has not started to travel in large quantities, and the air pollution is light and basically clean. All kinds of disturbing and noisy sounds are still at low tide, and the noise is small, which is beneficial to the health of hearing and nervous system. If you get up late, it will be difficult to breathe fresh air. Due to the large number of vehicles, some carcinogens, such as carbon monoxide, sulfur dioxide, nitrogen dioxide, hydrogen carbide, lead compounds, olefin compounds and other harmful substances, enter your respiratory tract and slowly accumulate in the human body, which will cause many diseases to a certain extent. According to the measurement, every time a car burns 1 kg gasoline, it can produce 10 cubic meter of harmful exhaust gas. As far as carbon monoxide is concerned, the concentration on the road before 6 o'clock is only 25% ~ 40% of that from 7 o'clock to 8 o'clock; From 8: 00 to 9: 00, its concentration will increase by about 10 times. In addition, the human respiratory tract is rich in water, and the alveolar area is 25 times larger than the body surface area after diffusion, so it is easier to contact, dissolve and absorb toxins in the air. Secondly, after getting up in the morning, I am clear-headed and energetic. After a night's rest and adjustment, the brain has recovered its vigorous ability, and the activities of bones and muscles are more coordinated after rest. At this time, exercising your bones and muscles, doing some physical exercise and memorizing some knowledge that needs to be memorized will make you feel very relaxed. Often using the morning time to remember will make you smart and knowledgeable. Regular exercise in the morning will make you healthy and live longer. Third, getting up early will increase appetite and promote gastrointestinal peristalsis. Experiments show that people who get up for an hour have the greatest appetite. A good breakfast will ensure enough energy for the whole morning. If you get up late, get dressed and eat in a hurry. Of course, you will find your meal hard to swallow. If you eat less, you can't guarantee that you have strong energy to work. If you can get up early to go to the toilet and clean your intestines, it will be better for your health. Because feces contain a large number of bacteria and metabolites, it is estimated that as many as 128 trillion bacteria are excreted from feces every day, accounting for 1/3 of the total feces. If these microorganisms stay in the intestine for too long, they will not only absorb too much water, resulting in dry stools, but also produce toxins that will be reabsorbed into the blood, causing headaches and fatigue. Fourth, you can have enough time in the morning to plan and arrange the work of the day, so that the whole day can be orderly and maintain a good order and mentality. On the contrary, if you often get up too late, you will be in a hurry after getting up, forgetting the east and the west, and you will be nervous and irritable when you work. Over time, nerve excitation lesions will form in the brain, which will be the root cause of many diseases. As the international longevity scholar Hoovland pointed out: "Among all the bad effects on people, the ones that have the shortest life and the earliest death are bad mood and bad mood." In a word, getting up early has many advantages. If you get up early and exercise properly, you can clear the lung and strengthen the spleen, invigorate the heart, lower blood pressure, prevent embolism, enhance gastrointestinal peristalsis, promote food digestion, adjust vision, increase vital capacity, promote the development of cerebral cortex inhibition, and be conducive to the full rest of nerve cells. Sun Simiao, a doctor in the Tang Dynasty, has clearly put forward the idea of "lying down and getting up early" in his "Golden Wings". According to the traditional habits of our people, it is advisable to get up at 5 ~ 6 in the morning, but it can also be advanced or postponed according to the changes of seasons. After all, people's energy is limited. If you get up too early, you will feel tired. Therefore, getting up early and going to bed early are linked. Get up early and go to bed early to ensure that the human body has enough rest and sleep time. People in China usually sleep at 9 ~ 10 pm. Some scholars believe that the following points are very important to ensure the quality of sleep. It is suggested to pay attention: First, sleep regularly, go to bed on time every night, and get up immediately after waking up in the morning. Over time, it will form a conditioned reflex and form a "stereotype of sleep motivation." This regular form can not only prevent insomnia, but also ensure the quality and quantity of sleep. Second, the bedding used for sleeping should be clean and soft, and should not be covered too thick, so as not to oppress the chest, abdomen and limbs and affect breathing and blood circulation. You can't cover your head with a quilt when you sleep to ensure fresh air. Fresh air contains 20% oxygen, and a person needs about 0.0l cubic meters of fresh air every minute. When you sleep with your head covered, you will feel suffocated because of the turbid air and lack of oxygen in the bed, and you may feel depressed, dizzy and chest tightness the next day. Third, don't overeat or play too much before going to bed, so as not to cause excessive excitement in the brain and affect sleep. Fourth, it is not advisable to sleep against the wind or turn on the electric fan to prevent catching cold and getting sick. American scientists believe that the earth's magnetic field has a direct impact on the human body. When your head is facing north and your feet are facing south, you can sleep safely and sweetly. The ancients said "early to bed and early to rise" and "striding in court". Since getting up early and going to bed early and exercising are so beneficial to the human body, we should follow suit and stick to it. The kind of person who forgives himself by fishing for three days and drying the net for two days, I wake up briskly in this spring morning and can't afford to get sleepy; I can't sleep in the heat, and I can't get up when I am tired; People who don't get enough sleep in autumn and don't want to warm their beds in winter will never enjoy getting up early.
