It is easy to get bored after lunch. This state has a word “food coma” in English, which translates to “food coma”, which is a physiological state of sleepiness after a meal.


First, after a meal, your body steals blood from other parts and sends it to the intestines in order to promote digestion. Dr. Rao compares this process with exercise. During exercise, blood is transported to the muscles, heart, and lungs, which allows the blood to get oxygen and muscle. When you are full, the process is reversed, and other organs, including the brain, give blood to the intestines to support intestinal activity.

But it’s not just the transfer of blood that makes you listless. Just like exercise, endorphins and cephalin are released all over the body. When you eat a lot of food, the intestines also release these hormones, in addition to somatostatin and tyrosin. The difference between these hormones is that they will relax you. Dr. Rao said: “In addition to keeping you quiet, these hormones will slow down the movement and emptying of the stomach, thus prolonging your feeling of fullness.” In fact, this is the body is trying to gain more for digesting food. time. The gut also produces a hunger hormone that stimulates your hunger. You eat too much, the hunger hormone will be reduced, let you control not to eat, eat too much will be killed. The combination of the effects of hormones and the transfer of blood will give your body and the digestive system a signal of “trouble to turn off the lights, I have to sleep”.

Third, the food we eat is mostly high in fat/high in sugar. After all, only a small number of people like salad. Dr. Rao said that fat can interfere with the emptying of the stomach. The more fat we eat, the longer they stay in the stomach. In fact, a small amount of fat will run into the intestine first, and then signal the stomach through the tyrosin peptide in the intestines, slowing it down. This means that you won’t feel hungry for a long time, preventing you from eating more food. In addition, temporary imbalances in insulin and glucose in the blood can also cause food coma to occur.

Dr. Rao said that this is a protective chain reaction that involves many parts. Everything is done to give the body time to recalibrate and return to normal. As long as your food leaves the stomach and the hormones return to normal levels and the blood returns to other organs, you can wake up from food coma. But all of this takes time.

Therefore, it seems that we should let the body be free and fall into a food coma until the end of nature. In fact, we don’t have to do this. The focus is coming

Registered dietitian Paul Salter suggests that walking for more than 15 minutes after a meal can improve the time it takes for food to pass through the digestive system and lower blood glucose levels. Moderate exercise can also redirect blood from the intestines to the muscles. Hawley Almstedt, a health and human services expert at Loyola Marymount University, says exercise can also neutralize the hormonal effects that make you sleepy, even if a small amount of exercise can stimulate or fight or react, making us feel Vigorous.

In addition, you can prevent food coma by eating other foods. For example, taking papain capsules or eating papaya directly, because the enzymes in papaya can make food move faster in the body; red peppers have the same promoting effect; hot coffee and tea can also promote gastric emptying, although the effect is not obvious .
