Parents say that after eating, they should have a good rest and can't do strenuous exercise. What's the situation?
Digestive juice doesn't come all the time. It takes a certain amount of time. Therefore, it's better to take a little rest before eating to prepare for the secretion of enough digestive juice. In this way, you will feel delicious and easy to digest. After eating, the stomach is full, and the stomach and intestines should be digested. To do these jobs, we need blood to help us. Otherwise, we can't do it well. If you go to engage in strenuous physical activities or nervous mental work immediately after eating, a lot of blood in your body will flow to your muscles or brain, leaving less to help your gastrointestinal work. In this way, the gastrointestinal work is not vigorous, food can not be well digested, over time, it will cause indigestion, bloating, stomachache and other problems. So before and after meals should rest for a while, especially just after dinner, don't do heavy work, also don't read and write. It's better to take a walk and do some light activities to help the stomach and intestines digest food better.
