Why do I feel sleepy every day after dinner? Is it a disease that I want to sleep right after eating?

Many people find themselves feeling sleepy after dinner. Why is this happening? Why do you want to sleep after dinner? There are two reasons. One is excessive fatigue during the day, and the other is eating too much, which results in insufficient blood flow and oxygen supply to the brain. Let's take a look at the detailed introduction provided in this article!

Why do I feel sleepy after dinner every day?

This is a situation that most students and office workers will encounter.

There are two main causes:

1. The point in time when a force is at its last.

In other words, the time period after dinner is the weakest stage of the day. You should know that for people who live a regular life, the daily distribution of physical energy is not linear. The day is spent in busy work and study, and the physical strength is almost exhausted.

Then at night, the physical energy reserves will have a step-like decline. In addition, we basically stay at home at night, and the relaxation of the mentality will also cause the body to feel slack from a subjective perspective, so sleepiness and fatigue are inevitable.

Of course, there are also some studies showing that the moon itself has a huge impact on the earth's tides, winds, and the state of the human body. This can also be regarded as a high-level argument.

2. Fatigue caused by the thermal effect of food.

Many people feel tired not only at night, but also after lunch, and want to sleep... Even on weekends, many people take a nap after breakfast. Please note that this happens after meals.

Why? Because after a meal, your stomach and intestines are in their peak working state. During this period, a lot of body energy and blood are concentrated in the stomach and intestines, which will cause slight muscle weakness and insufficient blood supply to the brain. As a result, you will feel weak, lazy, and drowsy. This is caused by the thermal effect of food.

Is it a disease to want to sleep right after eating?

Feeling sleepy after a meal may be due to high blood sugar levels after a meal.

If you feel sleepy for a long time, you should be careful whether it is due to high blood sugar, which may induce diabetes. The digestion process of food after a meal will produce a large amount of insulin. Although insulin can inhibit the rise of blood sugar and gradually stabilize blood sugar, it will also inhibit the decomposition of protein to a certain extent and produce some melatonin (a sleep hormone), which makes people sleepy. If blood sugar soars too fast and insulin is produced more, it may inhibit the secretion of "orexin". The increase of orexin will make people sleepy and make it easier for us to fall asleep.

In addition, if our cholecystokinin level is too high after a meal, it may cause drowsiness. Therefore, if we consume too much food after a meal, it will stimulate the secretion of cholecystokinin, which may make us feel sleepy. Generally speaking, obese people will cause higher secretion of cholecystokinin, so fat people are more likely to feel sleepy after a meal.

Why do we feel sleepy in winter?

1. Winter is dry and the body is prone to lack of water. If you do not replenish water in time, it will cause blood viscosity, reduce the oxygen content of the blood, and reduce the oxygen content of blood cells. This will make the brain and organs of the whole body unable to "fire at full power" and the correct use, resulting in fatigue and drowsiness. Therefore, you should replenish water in time.

2. Poor sleep. Many people like to play with mobile phones, watch TV, play games, etc. before going to bed, but this will make it more and more difficult to fall asleep. Various types of light will cause the secretion of melanin, making it difficult for people to feel sleepy, unable to fall into deep sleep and sleep too short, which affects the mental state during the day, thus disrupting the body's normal rest time, making the mental state poor during work and prone to drowsiness. Therefore, you should rest on time.
