When it s time to eat, I get sleepy, what s going on?

I often feel sleepy after lunch, is it because the blood is concentrated in the stomach and away from the brain?

Not really. Many people think that after eating, the blood of the whole body is concentrated in the digestive system to help gastrointestinal peristalsis and digestion, which will cause insufficient blood supply to the brain and make the brain lack oxygen, and people will feel sleepy, but this is not scientific.

As the most important organ of the human body, the human body will give priority to ensuring the blood of the brain**, if it is really as many people think that the brain is short of oxygen due to the reduction of blood supply, then the person should feel dizzy instead of simply sleepy. Foreign studies have indeed found that the blood flow to the brain not only does not decrease but increases after meals.

So why is there "food sleepiness"?

This is mostly related to the endocrine status of the human body after meals. When a person eats a high-carbohydrate food, the blood sugar rises, which inhibits the hypothalamus from secreting an appetite hormone, which is low in protein hormones, making the person feel tired and drowsy.

In addition, researchers in the United States found that the secretion of cholecystokinin may be related to drowsiness after meals, and the researchers tested the amount of cholecystokinin secretion and drowsiness scale scores of the subjects before and after meals, and found that there was a positive correlation between the two, that is, the more cholecystokinin secretion, the more sleepy people were. If the food you eat is too greasy, you will secrete a lot of cholecystokinin, which may also be the reason for feeling "sleepy" after eating.

What's the deal with being sleepy while eating? In fact, our food, it secretes a large number of digestive enzymes, and then begins to peristalsis, participates in our digestion, and then breaks down the food we eat into nutrients that are beneficial to our body.

This is normal, and I myself will get sleepy in the middle of eating.

Because when you eat, the blood will concentrate in the digestive system to help digestion, and when the brain lacks blood, there will be a slight lack of oxygen, and the blood is mainly used to transport oxygen and nutrients, and then you will feel sleepy.

But I haven't really tried to be sleepy to the same extent as you, I think your sleepiness is a bit serious, are you a person who often sleeps at night?

If your spleen is particularly weak, you may feel sleepy after eating, as the food is digested in the stomach after eating. In the process of food not being digested, many people will develop the desire to sleep. Because food is constantly running in the body, it requires the stomach to work non-stop, which will make you feel sleepy.

And you can't rest immediately after eating, if you rest immediately, the calories generated by these foods may accumulate in your body and make you gain weight. And after the food is digested by the stomach, the remaining part will need the spleen to digest, if your spleen deficiency is particularly severe, the body's ability to function will decrease, and it will also make you feel sleepy. Therefore, we cannot go to sleep immediately after eating, even if you want to sleep, you have to restrain yourself, and you must wait half an hour after eating before going to sleep.

If it's summer, you can also take a proper lunch break, after all, the summer days are relatively long, if you don't take a lunch break, it may make your spirit worse and make you have no energy to work.

After eating, if you go to sleep regularly, it will make you have a habit that your brain will secrete a signal to sleep after eating, and then you will want to sleep. So if you often sleep after eating, it will create a mindset that will make your muscles produce a certain memory, and after eating, it will make you feel sleepy. We must restrain ourselves from going to sleep immediately, because if we sleep immediately, it may make your stomach feel uncomfortable and make it difficult for food to digest.

Maybe your blood sugar is relatively high, and your blood sugar will be even higher after eating, so that your brain will be starved of oxygen, and you will want to sleep very much.

This may be due to the concentration of blood in the gastrointestinal tract after eating, which reduces the blood supply to the brain, causing drowsiness.

If you feel sleepy after eating, it may be because you are too full, and then the gallbladder contractile hormone will rise significantly, and then the person will feel particularly sleepy.

When a person eats a meal, the amount of glucose he consumes reduces the secretion of this protein hormone, which makes people feel sleepy.

Our bodies need energy to function. Whether it's exercising, sitting quietly, or even breathing itself requires energy. After food is ingested, it is broken down into glucose through the digestive system, which becomes our daily energy needs.

This digestive cycle also triggers various reactions in the body. While all foods are digested the same way, not all foods affect your body in the same way. Some high-protein foods, such as nuts, meat, eggs, and fish, contain an amino acid, tryptophan, which is a substance used by the body to produce serotonin.

Sleepiness after meals is a normal physiological phenomenon, don't worry too much, if the conditions allow for sleepiness, take a nap! If the conditions do not allow, get up and move, and it is not easy to get sleepy. After eating, the body will secrete some hormones, and these hormones act directly on the brain, which makes it easy to make people sleepy.

This also has something to do with our diet. Foods with high protein content require more protease and stomach acid to help with digestion; Digesting foods that are high in fat requires more bile. These foods will be more hungry because it takes longer for the body to empty them.

From waking up in the morning to about 6 to 7 hours after lunch, I was tired and tired from work. When noon came, everyone hurried to eat to quench their hunger. From the beginning of eating, the person's blood gradually collects into the gastrointestinal tract and other refinement and transmission systems, and begins to work

Stir. Processing. Decompose.

Digest the food, and then further refine it through various systems to convert it into protein, grape sugar and blood to meet the needs of the human body.

After eating, you will be sleepy, because after eating, the blood is concentrated in the gastrointestinal tract and abdomen, and the blood in the brain is reduced, which will cause sleepiness, which is a normal physiological phenomenon. Because after eating, the blood is concentrated in the gastrointestinal tract, so it is not advisable to exercise immediately after eating, and it is necessary to exercise half an hour to an hour after eating, otherwise it will cause poor digestion. In the long run, it can cause chronic gastric diseases, including chronic gastritis, gastroesophageal reflux disease, peptic ulcer, gastric tumors, etc., such as gastric cancer and gastric lymphoma.

Patients with chronic stomach problems should be careful to avoid spicy, too sour, too salty, and too sweet foods. Avoid mouldy foods and avoid smoked, pickled, nitrate- and nitrite-rich foods. Avoid starchy foods such as sweet potatoes, taro, pho, sausages, rice dumplings, potatoes, chestnuts, etc.

Have regular meals and a regular life. Maintain a good mindset and get enough sleep. As long as you pay attention to nourishing the stomach, stomach diseases are not easy**, and it is not easy to cause stomach problems.

This may be due to the intake of carbohydrates that causes the secretion of insulin, which causes an increase in the glycemic index and an increase in blood sugar. If this happens, be sure to get checked for diabetes.

Sleepiness after eating is not related to the decrease in blood supply to the brain due to the increase in blood supply to the digestive system. At present, the more reliable explanation is that hormones and neuromodulation make you always encounter drowsiness after meals.

Because after eating, most of the blood in the body is provided for digestion, resulting in less blood in the brain, and it is very easy to get sleepy.

Generally, it is easy to get sleepy after eating because some things in the body are restricted, so when we eat, we should not eat too much, because it is easy to get sleepy if we eat too much.

It may be because you have been lacking rest for a long time, so you will want to sleep after you have eaten and drunk, which is a very normal physiological phenomenon.

This can easily happen because there is a feeling of fullness in the body, which makes the body very warm.

People often feel sleepy after eating, because when the body ingests food, the gastrointestinal tract begins to digest the food, and the stomach grinds the food and excretes it into the intestines, which digest and absorb it.
