1. Avoid drinking tea immediately
Some people are used to putting down their rice bowls and holding teacups, and drinking tea right after eating. This is really a bad habit of doing more harm than good. Because drinking tea can increase the secretion of gastric juice and promote the digestion and absorption of food, especially meat, but tea contains a lot of tannins. After it enters the gastrointestinal tract, it can turn the protein in the food into a non-digestible coagulation substance. It hinders the body's absorption of protein, iron, and other nutrients. People who have the habit of drinking tea after meals may wish to gargle with tea after meals. This will not only remove greasiness and refreshing teeth but also prevent dental caries due to the fluoride in the tea.
2. Avoid eating cold drinks immediately
Eating cold drinks immediately after a meal will produce a strong cold stimulus to the digestive tract and cause strong peristalsis in the digestive tract, which may cause abdominal pain and diarrhea. At the same time, the intense changes in cold and heat will cause the blood vessels in the stomach to contract suddenly. If this happens, it will cause digestive disorders of the stomach, and even cause indigestion or other diseases.
3. Avoid smoking immediately
People who have a hobby of smoking often say: "A cigarette after a meal beats a living god." "Actually, smoking after a meal is harmful. According to the measurement of related personnel, the poison absorbed by smoking a cigarette after a meal is more than that of smoking 10 cigarettes in normal times. Because after eating, gastrointestinal peristalsis is strengthened, blood circulation is accelerated, and all capillaries in the body are in a state of relaxation. At this time, the body's ability to absorb smoke is "best". The toxic substances in smoke are easier to enter the human body than usual. It can increase the harm to the human body.
4. Avoid bathing or swimming immediately
After a meal, the human digestive system begins to work hard on digestion and absorption, and the required blood is greatly increased. If you take a bath or swim immediately at this time, the blood vessels in the skin will dilate and the blood flow will increase, the blood supply of the digestive tract will be reduced, and the digestive capacity will be weakened. Also, when the human body is immersed in water when swimming, on the one hand, the pressure of the water affects the peristalsis of the stomach and prevents the full mixing of food and gastric juice; on the other hand, the blood vessels in the abdomen are stimulated by cold water to cause contraction, resulting in insufficient blood supply to the stomach. Prone to stomach cramps, vomiting, or indigestion. Therefore, you should rest for 15 minutes before taking a bath after a meal, and go swimming after a half-hour rest. If it is an intense game, it should be held 2 hours after the meal.
5. Avoid immediate bowel movements
Many people have the habit of defecation immediately after meals, which is very detrimental to human health. Because the secretion of gastric acid and digestive enzymes increases after eating, the peristaltic function of the stomach is enhanced. If the stomach is filled with undigested food to defecate, the intra-abdominal pressure will suddenly increase, and gastric acid and digestive enzymes may flow back to the esophagus. Can form reflux esophageal ulcers. Therefore, people who have the habit of defecation immediately after a meal should gradually correct it.
6. Avoid going to bed right away
After a meal, due to the increased blood flow of the digestive organs, the blood supply to the brain is relatively reduced, and people feel tired and even drowsy. This phenomenon is more obvious after lunch. If you go to bed immediately after a meal, the peristalsis of the gastrointestinal tract will slow down, the secretion of digestive juice will decrease, and the food will not be fully digested. Furthermore, the stagnation of food in the stomach will also increase the excitability of the brain and make it difficult for people to fall asleep. Even if they are asleep, they will grind their teeth, talk in sleep, and have nightmares. Wait for a while to sleep after meals.
7. Avoid strenuous exercise
There is a folk saying that one hundred steps after a meal can live ninety-nine, meaning that proper exercise after a meal can help digestion and benefit human health. However, if you perform strenuous activities immediately after a meal, such as playing ball, running, and engaging in heavy physical labor, it will affect the digestion and absorption of food, which is bad for your health. Also, there is more food in the stomach after a meal and a heavier weight. If you exercise or work too much, it is easy to cause abdominal pain, gastroptosis, and other diseases. Therefore, exercise or labor should be arranged one hour after meals
