I want to sleep on coffee. Why? We search for the reason

What invigorates the morning? What can not drink at night, otherwise you will not fall asleep? And if you drink a lot, then you want to sleep. Guessed, what are we talking about? Of course, coffee.

Yes, it refreshes and energizes for the whole day, but sometimes after coffee it would be desirable to sleep. And some people, in general, it is contraindicated. So, what is more in it: harm or benefit? Let's understand.

Historical reference

It is one of the most popular beverages on our planet. The first mention of coffee dates back to the 15th century. According to legend, one shepherd noticed that the goats, after long transitions, having chewed the fruits of some plant, again became vigorous and mobile. Later coffee beans were used by slaves - this gave them the opportunity to work long without rest.

It is believed that coffee came to us from the East. Small cozy coffee houses first opened in Mecca. You could come here with friends and try a fragrant drink.

The beginning of the twentieth century was the beginning of a long confrontation between the two giants. Manufacturers of tea and coffee insist that it is their product is more useful. There are many negative reviews about coffee. Benefits and harm to health are the subject of numerous studies. And to this day, there are debates about the effects of caffeine on the body, on its ability to tone, improve performance, and invigorate for a long time.

Opponents argue that drinking coffee leads to the development of such dangerous diseases as coronary heart disease and diabetes mellitus. The drink negatively affects the central nervous system, reduces the defenses of the body in the fight against stress. In the evidence are given the data of scientific research, which over time is refuted and replaced by new facts.

There is also a very strange statement that you want to sleep on coffee . Why such a difference of opinion?

Coffee research

Scientists at Harvard University have been shown that caffeine does not lead to an increase in the number of cardiovascular diseases, as was thought before. Korean researchers studied the results of coffee drinking in grade 2 diabetes mellitus. According to their experiments, caffeine does not complicate the course of the disease, even if you drink 3-4 cups daily. But! Provided that it is a black drink, without sugar and any additives, including cream, syrups and sweeteners.

During the tests, a standard serving of 200 to 230 ml was used, containing up to 100 mg of caffeine. But the average person prefers portions much more - from 350 to 500 ml. At the same time coffee is often very sweet and hearty. It is erroneously assumed that additives neutralize the harmful effects of caffeine on the body.

There is another interesting experiment. Scientists in Pennsylvania compared the reaction of the body to the effects of natural ground and instant coffee. For several months, two groups of volunteers used them daily and noted their reaction. They tried to find out which coffee did not want to sleep during the working day.

As you know, a soluble drink contains less caffeine. Producers try to increase the effect of the drink due to various chemical additives and artificial caffeine. But, which is good for the manufacturer, it is not always useful for the consumer. Instead of vivacity and excellent state of health, many participants in the experiment noted the appearance of heartburn, headache, high blood pressure, drowsiness and apathy. In supporters of natural coffee, such symptoms were almost not observed.

Interesting facts in favor of coffee

Who should not drink coffee?

Despite the positive characteristics of the drink, there is a category of people to whom it is contraindicated.

1. With hypertension and other cardiovascular diseases, especially when it comes to the period of exacerbation, you can not drink coffee.
2. This product increases acidity, so it is contraindicated for ulcers, gastritis, various inflammatory diseases of the gastrointestinal tract.

During stress from coffee, I want to sleep. Why?

During stress, the body loses a lot of energy, resulting in fatigue, drowsiness and apathy. This is a kind of protective reaction. The human body and the nervous system need rest to gather strength and accumulate additional energy. If such pseudo-fatigue is extinguished by huge doses of coffee, all systems will eventually fail and a back reaction will begin. Getting into the body of caffeine instead of vivacity will cause drowsiness.

Therefore, it is necessary to change habits and menus urgently for a while. Strong coffee for breakfast is replaced by fruits and cereals with a high content of carbohydrates, vitamins and minerals. And from drinks choose black tea with lemon. He invigorates no less and gives strength throughout the day.

Everyone has his own norm

How long does it take to drink coffee in order to feel fine, be cheerful and healthy? Someone just enough to feel the fragrance to cheer up, and another person from coffee wants to sleep. Why such a reaction?

We are all different. And the reaction of the body to each individual. Considering the effect on the body of coffee, the benefits and harm to health depends on the rate of metabolism of caffeine. Those who have it high, need a constant addition of a drink of vivacity, sometimes up to 5-6 cups daily. Otherwise, there comes drowsiness and lethargy. And for someone and one serving is enough to make the day a success.

As you can see, there is no unambiguous answer and a single recipe. Yes, sometimes you want to sleep on coffee (why this happens, we already know), but this does not always happen. It all depends on the preferences and characteristics of the body. With proper intake of the drink gives a charge of vivacity and good mood.
