Eating, dressing and living are the basic guarantees of human life. Eating of course comes first, eating is actually getting energy for the organism. Three meals a day, it is important, some people do not pay much attention to, people in a hurry to work perhaps some forget breakfast, we can see from the news because of low blood sugar caused by fainting reports. Or do not eat on time. Breakfast should be around 7:00, lunch should be before 13:00, and dinner can be around 18:30. This is the rule that the body requires to follow, but of course it is accommodating the gastrointestinal tract. So people should not postpone eating for work, nor should they skip meals to lose weight. Eat on time in order to have bowel movements on time. Defecation is a very important thing, there is in and out? Only in and out, always be suffocated! Now people sleep late, and defecation ends up getting up early in the morning, when the gastrointestinal tract rests for the night and begins to move, and the gastrocolonic reflex occurs to promote defecation. So be sure to get up early, in order to defecate. Nowadays, many people are too busy to care about defecation. When the stool reaches the rectum, the soft texture of the stool stimulates the rectum to produce bowel movements, but people are so busy that they only have to hold it in. To go to work, to take the bus, to take the subway, to complete the tasks given by the boss, bowel movements have to be put aside. In fact, you may have missed the best time to have a bowel movement. When the time has passed, sometimes it is difficult to come back, just like stocks, miss the sale, only to wait again. By the time you have time to defecate, the water in the stool has been reabsorbed into your blood, along with the toxins in the stool, of course, into your body. Similarly, when you hold back a fart, it is actually absorbed by you, only to be excreted through other channels, such as your lungs. Hard stools, the rectum is not at all like, you can only strong efforts, spend more time to expel these stools, when you get used to this, the rectum began to become lazy, so that you do not defecate, you may have lost the pleasure of defecation, and then you have to challenge the constipation. It’s important to eat on time and have your bowel movements on time. When you have a bad bowel movement and harden your hard stool, chances are your anus is already bursting. Next, anal fissures are waiting for you. Nowadays, fewer and fewer people are starving, and people are demanding more and more exciting, spicy, and fragrant diets with a taste that the gastrointestinal tract can’t stand.
