Loosening the belt after eating can reduce the intra-abdominal pressure, increase the activity of digestive organs and the load of ligaments, thus promoting the aggravation of intestinal peristalsis, which is prone to digestive system diseases such as volvulus, abdominal distension, abdominal pain, vomiting, gastroptosis and epigastric discomfort.

Three things you can't do after dinner:

1. Don't eat fruit right away. Fruits contain flavonoids, which are converted into dihydroxy benzoic acid by intestinal bacteria after ingestion, while vegetables contain thiocyanate. Under the action of these two chemicals, thyroid function is disturbed, which can lead to non-iodine goiter.

Don't drink tea right away. Because the tannins contained in tea combine with protein and iron in food to form colloid or precipitate which is not easily absorbed, iron deficiency anemia and protein's disease may occur in the long run.

Don't smoke at once. Because the stomach peristalsis is accelerated after meals, blood circulation is increased, and capillaries are dilated, which promotes the absorption of harmful substances in cigarettes. Smoking after meals absorbs more than ten times the harmful substances in cigarettes as normal smoking. Please pay attention to your health.

Extended data:

After dinner, I didn't rush to drink tea, take a bath, sleep, walk, drive, eat fruit and untie my belt.

Listening to music after meals can help digestion, including listening to music after meals, rubbing your stomach after meals, going slow after meals, gargling after meals, eating a banana after barbecue, eating too greasy, drinking a cup of celery juice, and drinking yogurt or hot and sour juice after eating hot pot.
