What do you usually do after dinner? Brush your teeth, lie down and sleep for a while, loosen your pants or take a walk? I believe that many people know a health proverb: “100 steps after meals, live to 99”, and there are certainly many people will take it as kuigao. But after a meal is really suitable for a hundred steps? What other details we are accustomed to after meals, in fact, can be harmful to health? The habit of putting down your chopsticks and walking immediately after a meal is not desirable. From the perspective of digestion, the stomach is saturated after eating and needs sufficient blood sources to ensure good digestion, so if you walk immediately, it will lead to a reduction in the blood supply to the stomach and delay the secretion of digestive juices, thus destroying the normal digestion of the stomach and easily inducing functional indigestion. It is recommended to rest for about 30 minutes after meals before starting a walk. According to the different physical conditions of each person, it is appropriate to choose the time of walking after meals between 15 and 30 minutes. Sleep immediately after a meal Do not nap immediately after a meal, otherwise it will lead to a large amount of blood flow to the stomach, blood pressure drops, the brain oxygen supply and nutrition dropped significantly, there is a lack of blood supply to the brain. After waking up, you will often have dizziness, weakness of the limbs, the discomfort of soreness and weakness around the body. As the saying goes, “lie down after a meal, do not grow half a pound and four taels”, saying that immediately after a meal to bed is easy to get fat. It is recommended to rest for at least 20 minutes or so before going to bed. Smoking immediately after a meal Some people believe that “a cigarette after a meal, than the living gods.” However, medical research has shown that people smoke immediately after eating, which is extremely harmful to human health. Gastrointestinal peristalsis accelerates after a meal, the amount of blood circulation in the digestive tract increases, making it easier for the body to absorb the harmful components of smoke, and the degree of harm is even nearly 10 times greater than usual. Brush your teeth immediately after a meal Most people are accustomed to brush their teeth immediately after a meal, but in fact, this is not scientific. After people eat, a lot of acidic food will be attached to the teeth, softening the enamel on the surface of the teeth and even reacting with the calcium and phosphorus molecules in the axial layer of the teeth, separating the calcium and phosphorus and making the teeth soft and brittle. Brushing at this time will destroy the enamel and damage the dental health. Therefore, it is best to wait for half an hour after a meal before brushing your teeth. It is recommended that tartar can be removed before meals, and you can rinse your mouth immediately after meals to protect your teeth. If you take a bath immediately after a meal, the blood flow on the body surface will increase, and then the blood flow in the gastrointestinal tract will be reduced accordingly, which will weaken the digestive function of the stomach and intestines and cause indigestion. Therefore, the bath should also choose the right time, do not wash when hungry before meals, otherwise it is easy to cause hypoxia and temporary anemia; do not wash immediately after meals, it is best to rest for 1-2 hours, and then take a bath. Drinking strong tea immediately after a meal Many people like to drink a cup of “tea after dinner” to relieve grease to go. But this is not a good habit. Drinking tea immediately after a meal will not only affect the stomach’s digestion of food, resulting in indigestion, but also may increase the risk of stones. Tea contains tannic acid and theophylline, both of which can affect the body’s digestion of food. It is recommended to drink after half an hour after a meal. Relax the waistband of your pants after a full stomach Many people feel propped up after eating too much, and often relax the belt buckle so that the stomach is comfortable. But this will cause a drop in intra-abdominal pressure, weakening the support of the digestive tract, so that the mobility of the digestive organs and ligament load increases, prone to epigastric discomfort, and even intestinal torsion, leading to intestinal obstruction, gastric prolapse and other digestive system diseases. Therefore, we should develop the habit of “eating to seven percent full”, to know that many diseases are eaten out of the support.
