Why do people feel sleepy after eating at noon?

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.

When we take in food, the gastrointestinal tract begins to digest food, and the blood will be concentrated in the gastrointestinal tract, and the blood supply to the brain will be reduced by concentrating on digesting food and absorbing nutrients, so it is normal to feel sleepy after eating.

To reduce sleepiness after meals, you should minimize the intake of white rice and steamed buns, which are foods with a high glycemic index, at lunchtime, and do not consume sugary drinks. Do not sit down immediately after eating, it is recommended to walk slowly for 20-30 minutes.

Studies have found that the cholecystokinin secreted in our body increases significantly within 2 hours after a meal and begins to fall back two hours later. And when we start to get sleepy, it starts to increase significantly after eating, and then it slowly decreases, which is up to you to show that there is a positive correlation between cholecystokinin and our sleepiness.

Sleepiness after meals is a typical symptom of spleen deficiency.

One of the main functions of the spleen is to be responsible for transport and digestion. Mizutani into the stomach. After the initial digestion by the stomach, it is sent down to the spleen, which further digests and absorbs it.

After that, the spleen qi helps to return the essence to the lungs, and from the lungs to all parts of the body to nourish the internal organs and organs, so when the spleen qi is healthy, the person's digestive function is good, and the body is rich in muscles and full of energy.

When the workload of the spleen increases suddenly after eating, the spleen system needs more qi and blood to help the spleen complete the digestion, absorption, and transportation of nutrients to food, which will inevitably lead to a decrease in blood and qi in other organs of the body, and when the brain qi and blood ** decrease, symptoms of drowsiness will appear.

Introduction, many parents will encounter the situation that the baby wants to go to the time as soon as we finish eating, when we are full, we are often at a loss when we encounter this situation, and I will write about what is going on when I get sleepy after eating!

Reasons for being sleepy after eating:

In fact, the principle is very simple, after eating, the baby's stomach continues to expand, compressing the auxiliary artery behind the stomach, and the compression of the artery will affect the normal delivery of blood to the brain, resulting in a lack of oxygen to the brain, causing sleepiness.

After eating, it is easy to get sleepy, because of the need for digestive exercises, so the blood flows more to the stomach, and the brain is temporarily ischemia, that is, there is a lack of oxygen sent from the blood. So, at this time, why are people with a weak spleen easy to get sleepy after eating? This has to start with the process of digestion, absorption, and transportation of nutrients by the spleen to food.

The Yellow Emperor's Neijing: Meridians and Meridians Chapter 21 has this discussion: "Drinking into the stomach, overflowing essence, and losing in the spleen; The spleen is scattered and the essence is returned to the lungs; Drain the waterway and lower the bladder; The water essence is four cloths, the five meridians are parallel, and the yin and yang of the four times and five organs are combined, and the degree is normal. "It can be seen that one of the main functions of the spleen is to be responsible for transportation and digestion.

After the initial digestion of the stomach, the water valley is sent to the spleen, which is further digested and absorbed. Later, with the help of the spleen, the essence and qi are returned to the lungs, and from the lungs to all parts of the body to nourish the internal organs and organs, so when the spleen is healthy, the person's digestive function is good, and the body is full of energy. If the spleen is weak and the spleen is not healthy, the spleen's own strength cannot complete this task, and the body needs to mobilize more qi and blood to complete this task.

Workaround:

When the workload of the spleen increases suddenly after eating, the spleen system needs more qi and blood to help the spleen complete the digestion, absorption, and transportation of nutrients to food, which will inevitably lead to a decrease in blood and qi in other organs of the body. When the brain qi and blood ** decrease, there will be symptoms of drowsiness, and those with spleen deficiency will have symptoms of being sleepy after meals, but they can still control not sleeping; People with a weak spleen must sleep after eating, otherwise they will not be able to continue working; What's more, as soon as they started eating, they were uncontrollably sleepy. In this case, after acupuncture treatment, the symptoms of drowsiness after meals will gradually alleviate until they disappear.

Use your brain right away. You can relax, and if you are too sleepy, you can lie down or half-lie down for a while. But be careful not to sleep too long.

Because rice contains so many carbohydrates, people who consume too many carbohydrates will feel sleepy.

This is called "food sleepiness" When a person eats a lot of food, a large amount of blood in the body runs to the stomach and intestines, which is cerebral ischemia, and will be sleepy, in addition, after the gastrointestinal tract begins to work, brain activity can also be inhibited through nerve stimulation regulation, and you will also feel sleepy This is a normal physiological phenomenon, it is best not to adjust it deliberately, it is better to rest for a while after eating and then do other things Otherwise, the blood can not reach the stomach and intestines, which will affect digestion

If you go to bed immediately after eating, digestion will occupy a large amount of blood, and the brain will be poor and even dangerous due to the lack of blood. On the other hand, due to the slow peristalsis of digestion, it is easy to cause gastrointestinal diseases; The third aspect is that calcium is easy to accumulate and stones are easy to form; Fourth, it is easy to gain weight.

Because after eating, the blood increases to the digestive system** and decreases the nervous system (mainly the brain) and motor system**, so you will feel weak and want to sleep.

Also, don't eat too much, and not being able to do physical activity immediately after a meal, and taking a short nap after lunch, these are all related issues.

balance of the human body, and well-being. "

To put it bluntly, after you finish eating, all the blood goes to the gastrointestinal tract to digest the food, and at the same time, the blood supply to the brain will be reduced accordingly. Blood is a carrier of oxygen cells, and if the blood in the brain decreases, the amount of oxygen cells will also decrease. There is so little oxygen in the nerve center that the person is sleepy and wants to rest in bed.

Therefore, rest (sit or stand) for half an hour after eating, and wait for the blood to balance before exercising. (Another: Stand and watch TV, don't stand up jerk after eating.)

Go to the hospital to see if it is anemia, because after eating, the blood goes to the stomach to help transport nutrients, and a small part of the blood reaches your brain. As a result, you will not have enough blood supply to your brain, and you will be sleepy after eating.
