2. From the perspective of human physiology, defecation, like eating, is an innate instinct. Unfortunately, for various reasons, there are very few people who can defecate correctly. Correct defecation methods should include the following points: defecation should be controlled at 1 ~ 2 times a day. It is best to use the least amount of force, the shortest duration, discharge smoothly, and feel relaxed after defecation. Before and after breakfast is the best time to defecate, because it conforms to the physiological laws of the human body. For example, the stimulation of food can accelerate gastrointestinal peristalsis, which is easy to produce a sense of convenience, so it is most appropriate to defecate about 20 minutes after breakfast. In addition, after getting up in the morning, the colon will also move upright, so many people have to go to the toilet after getting up, which is of certain significance for anal health care and physical fitness. Carry out defecation according to the law of defecation process, that is, after the previous defecation, rest quietly for a while, and then carry out the second defecation when the feces move down from the upper part of the rectum to produce a second defecation feeling, gradually increasing the intensity and facilitating the discharge of feces. Do not forcibly defecate during the interval of defecation, otherwise it will easily lead to adverse consequences such as anal injury, relaxation or rectal prolapse. It is advisable to make a quick decision. The actual defecation action takes a very short time, each defecation action is only a few seconds, and the total time of two or three defecation actions is only about 1 minute. If you have been squatting in the toilet for more than three or five minutes and still feel uncomfortable, it's time to end. Squatting for too long is easy to induce hemorrhoids.
In recent years, some experts have put forward many new ideas about male urination. The first is the urination posture. It is recommended to take a squat position like a woman. The advantage is that it is less affected by cancer. It turns out that squatting urination can cause a series of muscle movements and related reflexes, accelerate the removal of intestinal waste, shorten the residence time of feces in the intestine, and reduce the reabsorption of carcinogens such as hydrogen sulfide, indole and fecal odor, thus protecting the intestinal mucosa from carcinogens. According to the survey data, the cancer rate of squatting men is 40% lower than that of standing men, which is one of the mysteries of the low incidence of intestinal cancer in Indian men who are used to squatting.
4. As the saying goes, "There is a standing phase when standing, and a sitting phase when sitting". The correct sitting posture is: sitting on a wooden chair with a backrest, with the hips and knees flexed 90 degrees, and the lumbar spine and backrest as close as possible, leaving no gap. After sitting for 1 ~ 2 hours, you should stand up and exercise your waist. Adhering to the correct sitting posture is very important for the health of the spine, especially the lumbar spine. There is a simple reason. Among the three postures of standing, sitting and lying, sitting posture is the most harmful to lumbar health. Wrong sitting posture and overwork will greatly increase the degree and time of waist bending. According to statistics, the maximum frequency of lumbar flexion can reach 3000 ~ 5000 times a day. This kind of excessive and repeated flexion is the most common cause of lumbar diseases, and it is necessary to prevent it.
Eating seems simple, but in fact it contains science. First of all, try to chew slowly and chew a bite of food at least 20 ~ 30 times. Taking cancer prevention as an example, experts have observed through experiments that chewing for 30 seconds can reduce the toxicity of carcinogens. If a bite of food is chewed for 30 times and then swallowed, the anti-cancer effect of saliva can be fully exerted. Therefore, a bite of food should be chewed at least 20 times, and it is ideal if it can reach 30 times. Second, chewing should be bilateral, not unilateral. Unilateral chewing can lead to muscle tension or shoulder pain on one side, or loose teeth on one side, which may lead to cheek asymmetry and even affect hearing. A research team from Tokyo Dental University surveyed more than 200 people and found that continuous unilateral chewing can reduce the hearing of this ear. Chewing only the front teeth will reduce the hearing of listening to high notes; Chewing only with molars will reduce the hearing of bass.
6, yawning looks indecent, but it can help men have a good and firm erectile function. Sexologists point out that yawning can make more oxygen enter the lungs through deep inhalation, promote blood oxygen exchange and promote the brain to produce a substance called nitric oxide.
