Be careful not to go to bed immediately after dinner. When I was a child, the old man in my family always threatened me that my intestines would stick together when I slept after dinner, but actually I didn't. But we can't sleep after meals, because sleeping after meals will slow down our gastrointestinal movement and affect our stomach's digestion of food. So sit and walk for half an hour after dinner, and don't go to bed right away.
Then, don't smoke after dinner. Although it is always said that smoking after meals is very bad for our stomachs, because our blood circulates quickly after meals, because our stomachs are digesting, if we smoke, the accelerated blood will quickly move the nicotine we just inhaled into our bodies, which is why smoking after meals is very harmful to our health. It's best not to smoke.
Then don't take a shower for half an hour after dinner. I'm not allowed to take a bath after dinner at home, because it's also harmful to my health. Taking a bath after a meal will affect the blood circulation of our body, leading to indigestion in the stomach and possibly dizziness. So don't take a shower after dinner. You'd better let your stomach digest before washing.
