Why do people want to sleep when they are full?

Sleeping after a meal is related to the digestive law of the human body. When we eat food, the gastrointestinal tract begins to digest food, and the blood will concentrate on the gastrointestinal tract to digest food and absorb nutrients, so the blood supply to the brain will decrease, so we will feel sleepy after meals.

If you are often sleepy after a meal, you will feel very tired after eating, which may be an alarm signal from your body. It is warning you that the current diet structure is not healthy enough, which is likely to lead to diabetes. Dr. Beth Rilton, a nutritionist at Duke University's Comprehensive Medical Research Center in the United States, said that one-time intake of simple carbohydrates such as white sugar, white flour and sweet drinks in the daily diet can easily lead to a sudden increase in blood sugar, so that cellular insulin receptors stop receiving insulin, and excessive glucose accumulates in the blood. At the same time, the pancreas "strives" to produce more insulin. This vicious circle makes human organs too burdened to rest, which will lead to drowsiness, fatigue and overdraft.
