When the core is relaxed, the body will shorten all the muscles around the waist and abdomen due to gravity. The pre-shortened muscles can't exert force, so the abdominal muscles can't squeeze the abdomen normally when breathing when relaxing. Digesting food is done independently by the digestive tract, and it does not rely on exercise to promote intestinal peristalsis and help digestion. On the contrary, any exercise will affect the blood distribution. For example, after walking, the oxygen consumption of both lower limbs increases, which will reflexively reduce other organs.

From the point of view of health, half an hour after a meal is exquisite, generally half an hour after breakfast, don't rush to exercise, so as not to cause indigestion. You can massage your knees and smooth your stomach. Half an hour after lunch is used to adjust the mental state of the body. In my opinion, the so-called health preservation is actually a "leisure way". You can see that farmers in the past were sent to the fields to eat, chew and bend over to work in the transplanting season. That is, people who have suffered a lot.

If you are full for 7-8 minutes, you can take a walk after the meal 10-20 minutes, which gives your stomach a certain digestion time and will not cause stomach discomfort during the walk. Because if you just sit for half an hour after eating, it is not conducive to the digestion of food. If you stand completely within half an hour after a meal, the food in your stomach will fall. If you do this every day, it may lead to gastroptosis. So, sit and rest for a few minutes within half an hour after dinner.

There is an old saying that "walk a hundred paces after a meal and live to be ninety-nine". It literally means that going out after meals is good for health and longevity. Many people think they understand the meaning of this sentence, but in fact many people misunderstand the true meaning of this sentence. In fact, this is an optional topic for most people. After breakfast, everyone is busy with work and school. After lunch, they can have a rest instead of walking and exercising. Only after supper can they relax and go out for a walk.
