Why eating meal bring laziness.

Have you ever noticed that in the afternoon and at night, despite being fully mentally awake and active, after eating, you suddenly feel drowsy and drowsy?

If you feel this way, you are not alone. In fact, millions of people experience it, which is also called food coma in medical language, which is also experienced by different animals.

But what is the reason? Now scientists think they have found the answer.

In fact, it may be related to post-meal drowsiness or the formation of sluggish and long-term memories. This was revealed in a medical study conducted in the United States.

Research from New York University has shown that after a healthy diet, everyone suffers from lethargy and drowsiness, and in fact this reaction is seen not only in humans but also in most animals.

"Our research suggests that the 'relaxation and digestion' response is the result of an evolutionary process that helps create long-term memories," said Professor Thomas Crew, of the research team.

The research team examined a sea creature called the California sea slug because it is a very powerful creature for such research and its brain neurons are 10 to 50 times larger than most living creatures.

Scientists have also looked at past work on the relationship between food and the brain.

"Insulin is released after eating in humans, which allows body cells to absorb nutrients into the bloodstream and convert them into fat and store them for a long time," said Nikolai Kikyushkin, another member of the research team. The effects of insulin on the brain are minimal, being replaced by the release of another hormone, such as insulin, which is essential for brain functions, including the formation of long-term memory, but is dependent on calories. But it doesn't happen.

However, he said, there are two active modules for the human body to release insulin-like compounds, a metabolic module that represents insulin, which regulates the balance of food and energy, and a brain module, which is similar to insulin. Relies on compounds and controls memory formation.

The researchers said that the organism they studied had human-like features of the hormone insulin systems, both of which helped in the evolution of nutrition, memory and behavior, but in C-slug these functions remained together, while humans I became partially independent.

Researchers say it remains to be seen whether food coma in humans is part of the evolutionary process of the past or an important part of memory formation, but it has already been proven that sleep is a long-term memory in many organisms, including humans. Is required to store.

He believed that the feeling of lethargy or drowsiness after a meal could be a similar means of preserving the memory of the food that may come to mind in the future, because memorable food is always alive in the mind.

The results of the study were published in the medical journal Nature Research Journal Scientific Reports.

Earlier this year, a study by the Asripps Research Institute in the United States found that the behavior of various living things, including humans, suggests that there is something special about it.

Researchers believe that humans and other living things have a special built-in signal that keeps them awake and alert when they are hungry. These signals help people find food, but when one eats on a full stomach, these signals disappear and are replaced by fatigue and drowsiness.

Some experts believe that this is due to changes in the blood circulation after eating, because the blood flow in the small intestine increases dramatically after eating.

When the blood flow in the stomach increases to speed up the digestive process, the rate towards the brain slows down, causing the brain to feel drowsy. In the past, research has shown that certain foods cause more drowsiness than others.

Similarly, a 2018 study found that people who consume more vegetables and olive oil, etc., are less likely to experience this kind of drowsiness after eating.

The researchers said that a healthy diet reduces the chances of drowsiness during the day, while foods high in fat or carbohydrates affect the body's clock's sleep pattern, which can lead to drowsiness.
