What invigorates in the morning? What can not be drunk at night, otherwise you will not fall asleep? And if you drink a lot of it, you will want to sleep. Guess what it's about? About coffee, of course.

Yes, it is refreshing and energizing for the whole day, but sometimes after coffee you want to sleep. And for some people, it is generally contraindicated. So, what is more in it: harm or benefit? Let's figure it out.

Historical background

This is one of the most popular drinks on our planet. The first mention of coffee dates back to the 15th century. According to legend, one shepherd noticed that after long journeys, after chewing the fruits of some plant, goats became vigorous and mobile again. Later, slaves began to consume coffee beans - this gave them the opportunity to work for a long time without rest.

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

The beginning of the twentieth century was the start of a long confrontation between the two giants. Tea and coffee producers insiston what exactly their product is more useful. There are a lot of negative reviews about coffee. He alth benefits and harms are the subject of numerous studies. And to this day, there are disputes about the effect of caffeine on the body, about its ability to tone up, increase efficiency, 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. The drink negatively affects the central nervous system, reduces the body's defenses in the fight against stress. The evidence is provided by scientific research data, which over time are refuted and replaced by new facts.

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

Coffee Research

Scientists at Harvard University have proven that caffeine does not lead to an increase in the number of cardiovascular diseases, as previously thought. Korean scientists investigated the results of coffee consumption in type 2 diabetes. According to their experiments, caffeine does not complicate the course of the disease, even if you drink 3-4 cups daily. But! Assuming it's a black drink, no sugar or additives, including cream, syrups and sweeteners.

During the studies, a standard serving of a drink of 200 - 230 ml was used, which contains up to 100 mg of caffeine. But the average person prefers much larger portions - from 350 to 500 ml. At the same time, coffee is often very sweet and satisfying. erroneouslysupplements are supposed to neutralize the harmful effects of caffeine on the body.

There is another interesting experiment. Pennsylvania scientists compared the body's response 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 figure out what kind of coffee makes you sleepy during the workday.

As you know, instant drink contains less caffeine. Manufacturers are trying to increase the effect of the drink through various chemical additives and artificial caffeine. But what is good for the manufacturer is not always good for the consumer. Instead of cheerfulness and excellent he alth, many participants in the experiment noted the appearance of heartburn, headache, high blood pressure, drowsiness and apathy. Proponents of natural coffee had almost no such symptoms.

Interesting facts about coffee

Who can't drink coffee?

Despite the positive characteristics of the drink, there is a category of people for 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.
3. With nervous disorders, depression, insomnia, coffee is not recommended. In such states, it will excite the nervous system even more, which will aggravate the course of diseases.
4. Pregnancy is not an absolute contraindication to the use of the drink, but you should not get too carried away with it. During this period, the body of the future baby is being formed, an excess of caffeine is highly undesirable.

During the stress of coffee, you want to sleep. Why?

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

Therefore, for the time being urgently neededchange habits and menus. Strong coffee for breakfast should be replaced with fruits and cereals that are high in carbohydrates, vitamins and minerals. And from drinks choose black tea with lemon. It invigorates no less and gives strength throughout the day.

Everyone has their own norm

How much coffee do you need to drink to feel great, be alert and he althy? It is enough for someone just to feel the aroma to cheer up, while another person wants to sleep from coffee. Why such a reaction?

We are all different. And everyone's body reacts differently. Considering the effects of coffee on the body, the he alth benefits and harms depend on the metabolic rate of caffeine. Those who have it high need a constant addition of a vigor drink, sometimes up to 5-6 cups daily. Otherwise, drowsiness and lethargy ensue. And for someone, one serving is enough to make the day a success.

As you can see, there is no single answer and no single recipe. Yes, sometimes coffee makes you sleepy (why this happens, we already know), but this is not always the case. It all depends on the preferences and characteristics of the body. When taken correctly, the drink gives a charge of vivacity and good mood.
