Smoking immediately after a meal Some studies have shown that smoking after a meal is more harmful than the usual smoking. Because after eating, the human gastrointestinal motility frequent, blood circulation accelerated, tissue cells biological respiration enhanced. Smoking at this time, the lungs and other tissues to absorb smoke greatly increased, the absorption of nicotine, nicotine and other harmful substances also increased. Tip: As always, smoking is harmful to health, it is best to resolve to quit completely. Eat fruit immediately after a meal Eating fruit immediately after a meal will be blocked in the stomach by the food eaten in the first place. The fruit is rich in monosaccharides, and if it stays in the stomach for too long, it will ferment and produce gas, and produce toxins under the action of bacteria, thus causing bloating, abdominal pain or excessive stomach acid and other uncomfortable symptoms. Tip: fruit is best eaten between meals, so that the body is conducive to the full absorption of various vitamins and minerals. Drinking cold drinks after eating Most of the body’s blood is concentrated in the gastrointestinal and other digestive organs after meals, gastrointestinal activity is relatively active. At this time to drink cold drinks, will dilute stomach acid, but also the stomach wall mucosa vasoconstriction, inhibition of digestive gland secretion, gastric activity is weakened, it is difficult to digest the food completely, easy to produce appetite and fullness and other indigestion symptoms. Eating cold food after meals is also bad for the heart. Tip: Hot weather should not (especially not after meals) drink more cold drinks, usually or in due time to drink some cool water as the first choice. Immediately after the meal, bathing in warm water stimulation, the limbs and the whole body skin vascular expansion, resulting in blood pooling body surface, gastrointestinal blood flow will correspondingly decline, digestive secretion reduced, affecting the digestive absorption function. In addition, immediately after the meal bath, but also lead to insufficient blood supply to the heart, inducing cardiovascular disease. Tip: 1 to 2 hours after the meal bath is more appropriate, when the body is more energy, can reduce or avoid the elderly and frail people in the hot bath is prone to accidents such as deficiency. Loose trouser belt immediately after eating a full meal, the abdominal cavity pressure suddenly fell, the support of the digestive tract weakened, resulting in increased load on the digestive organs and ligaments, prompting increased gastrointestinal peristalsis or disorders, both affecting food digestion, but also easy to cause bloating, abdominal pain and other symptoms, which in the long run can also lead to gastric prolapse, causing abdominal discomfort and other digestive system diseases. Tips: the usual diet should pay attention to moderation, dinner is best controlled in eight minutes full, such as the occurrence of too much, can be used to gently massage the abdomen to help the stomach food digestion as soon as possible to empty. Singing loudly after eating After eating a full meal, the human stomach volume increases, the stomach wall becomes thinner, and blood flow increases. Singing at this time will cause the diaphragm to move down and the abdominal cavity pressure to increase, causing indigestion in mild cases and gastrointestinal discomfort and other diseases in heavy cases. In addition, if you drink alcohol while eating, with the stimulation of alcohol, the human larynx and vocal cords are naturally congested, and singing loudly at this time will increase the congestion and edema of the larynx and vocal cords, which will easily cause acute inflammation of the vocal cords and throat, with symptoms such as hoarseness and sore throat.

Especially after drinking alcohol, you should control your pronunciation appropriately and never shout excessively with the excitement of alcohol. Go poo after a meal The secretion of stomach acid and digestive enzymes increases after a meal, and the peristaltic function of the stomach is enhanced to help digest food. If the stomach is filled with undigested food when defecating, due to holding the breath so that the abdominal pressure suddenly increased, gastric acid, digestive enzymes may reflux to the esophagus, which can form a reflux esophageal ulcer. Immediately after the meal stool, can also promote pyloric smooth muscle dysfunction, bile reflux, resulting in gastric mucosa congestion, edema and even inflammation. Tip: It is a good habit to develop a regular bowel movement every day, but avoid doing it immediately after meals, usually when you wake up in the morning on an empty stomach is better. For people who have the habit of defecating immediately after meals, it is best to gradually correct them. Sleep immediately after eating The blood flow to the digestive organs increases after meals, and the blood supply to the brain is relatively insufficient, so people feel tired and even drowsy. If you sleep immediately after eating, the peristalsis of the gastrointestinal tract slows down, the secretion of digestive juices decreases, the food can not be fully digested and absorbed, which can cause nutritional deficiencies. At the same time, after a full stomach pressure increases, if the immediate lie flat, it may cause gastroesophageal reflux and vomiting and other symptoms, often this will also cause reflux esophagitis. Tips: after the meal should be appropriate to sit for a period of time (at least 30 minutes), to wait for the food in the stomach to be digested and emptied and then lie down to rest for good. Driving immediately after eating The digestion of food by the stomach and intestines requires a lot of blood, resulting in temporary relative ischemia of the brain, fatigue and drowsiness, the reaction also becomes sluggish, in the driving process, especially when an emergency occurs, easily lead to errors in judgment and operation, so that the probability of a car accident is greatly increased. Tip: The driver’s hand on the steering wheel is not a child’s play, “happy out of the car, safe return home” should always remember.
