First， it is inappropriate to read and watch the dramas while eating. Reading and watching the drama will stimulate our sympathetic nerves， inhibiting the gastrointestinal digestive function； while eating will stimulate our parasympathetic nerves， enhancing the secretion of digestive fluid and strengthening digestion and absorption. This will lead to neurological disorders ... Secondly， it is of no good to squat when eating. When eating， gastrointestinal needs a lot of blood to help digestion and absorption. Squatting will inhibit the refluxing of blood of the lower extremities， affecting the digestion and absorption of food. In addition， do not talk when eating. If you talkwhile eating， the food will not be fully chewed， the peristalsis of the stomach and intestine willweakenand the digestive secretion will decrease， thus increasing the burden of stomach， resulting in indigestion， anorexia and gastrointestinal diseases. In addition， remember not to gobble when eating. Food that enters the stomach without being chewed will aggravate the burden of the gastrointestinal tract and affect digestion and absorption. Finally， don't eat when the food is still hot. Human esophageal wall， composed of mucous membranes， can only tolerate food of 50～60℃. Once over it， the mucosa of the esophagus will be scalded.
