After eating, we have all felt a sudden need to sleep. Called post-prandial drowsiness, this little slump occurs for different reasons.
This phenomenon is particularly related to blood circulation. It should be known that to facilitate digestion, the blood flow increases largely in the direction of the stomach and the intestine.
As a result, the amount of blood that circulates in the rest of the body, including the brain, is less. This leads to a feeling of fatigue in some people, explained Tomonori Kishino, professor of health sciences at the Japanese University of Kyorin, quoted by the Time.
Several studies have also shown that post-prandial sleepiness is essentially due to the composition of the menu. Indeed, the more the foods ingested are rich in fat and carbohydrates, the more the eyelids will tend to become heavy, and this, due to the production of insulin.

Researchers from «The Script Research Institute» have for their part shown that the consumption of animal proteins and salt promotes drowsiness. To avoid being sleepy, scientists recommend opting for balanced meals and avoiding eating too much. In this way, digestion will be faster, and therefore less energy-consuming.
