Despite the fact that humans have gone far in their development from other animals, some of the body's reactions remain similar to those of animals in the wild. For example, why do you want to sleep after a meal, regardless of whether you are in a convenient place for an afternoon rest or not?
The reasons for this phenomenon are almost the same as those of a full lion or domestic cat. Only, unlike the natural world, drowsiness at the height of the working day is not entirely appropriate.
Why is food and sleep so tied?.
There is a simple and understandable explanation on a philistine level - when you take food, your body casts all its energy resources for digestion and full digestion of food that has got into the stomach. Therefore, blood flows into the lower half of the body, while the flow of blood to the brain decreases, and its oxygen supply deteriorates.
In such conditions it is difficult to keep cheerfulness and the person immediately starts to sleep. Therefore, after eating, you want to sleep and fight it is almost impossible, because it is a deep reaction of the body. It remains only to think of what to do in this situation.
Noticing this pattern, the Spaniards came up with a siesta, and the Japanese allowed at their enterprises an afternoon nap. Guided, apparently, by the principle that if any process can not be prevented, then if it does not lead, then at least make it official and legal.
As scientists have recently found out, drowsiness can be caused not only by poor supply of the brain with oxygen. The point is still in the "hormone of vivacity" - orxine, which is produced by a special department of the brain and is the main regulator of the "sleep-wakefulness" regime.
A large content of orexin in the blood causes a burst of energy - a person wants to turn mountains, eat a bull, love the whole world. The animal sends this hormone to the hunt, replacing their languid fetching in the shade for running around in search of food. The level of this hormone is then increased, then decreases within a day, according to circadian (ie, associated with alternation of night and day) rhythms..
The regulation of the amount of orexin is determined not only by external factors, but also by internal factors. In the process of saturation of the body, leptin is released - the hormone of "satiety" - that's what suppresses the production of our hormone of vivacity. Glucose in large quantities also can block the activity of the body. Therefore, do not be surprised that even from coffee you want to sleep, if you poured into it four tablespoons of sugar.
How to deal with sleepiness?
Sleep after eating is a healthy body condition, so you do not need to fight it. If possible, then it's better to have a rest after dinner 20-30 minutes. In most cases, this time is enough for the return of strength and vigor. But what if you want to sleep after dinner, and an important and important event ahead of you, which requires complete concentration and concentration?
First, you can postpone lunch. Secondly, you can replace fatty or carbohydrate-rich foods with something lighter, preferably containing a lot of protein. Cottage cheese, eggs, vegetable salads, fruit will perfectly suit. The feeling of hunger will recede, and you will be able to deal with important matters and dine a little later.
