What invigorates in the morning? What can not be drunk at night, otherwise you will not fall asleep? And if you drink it a lot, you will want to sleep. Guess what it is about? Of course, about coffee.
Yes, it refreshes and energizes for the whole day, but sometimes you feel sleepy after coffee. And for some people it is generally contraindicated. So, what is more in it: harm or benefit? Let's get it right.
Historical reference
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 the goats after long transitions, chewing the fruits of a plant, again became vigorous and mobile. 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 houses first opened in Mecca. You 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 manufacturers insist that their product is more beneficial. There are a lot of negative reviews about coffee. Health benefits and harms are the subject of numerous studies. And to this day, there is debate about the effect of caffeine on the body, its ability to tone, increase working capacity, invigorate for a long time.
Opponents argue that drinking coffee leads to the development of dangerous diseases such 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 cites scientific research data, which over time is refuted and replaced by new facts.
There is a very strange statement that you want to sleep with coffee . Why is there such a difference of opinion?
Coffee Research
Scientists at Harvard University have proved that caffeine does not lead to an increase in the number of cardiovascular diseases, as previously thought. Korean scientists examined the results of drinking coffee with diabetes mellitus 2 degrees. 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 all kinds of additives, including cream, syrups and sweeteners.
During the studies, a standard portion of the drink 200 - 230 ml was used, which contains 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 satisfying. It is mistakenly assumed that supplements 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 consumed them daily and noted their reaction. They tried to find out what kind of coffee you don’t want to sleep during the working day.
As you know, a soluble drink contains less caffeine. Manufacturers are trying to increase the effect of the drink through various chemical additives and artificial caffeine. But, which is good for the manufacturer, it is not always useful for the consumer. Instead of vigor and well-being, many participants in the experiment noted the appearance of heartburn, headache, high blood pressure, drowsiness, and apathy. Supporters of natural coffee have almost no such symptoms.

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

During stress from 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 protective reaction. The human body and nervous system need rest in order to gather strength and accumulate additional energy. If you quench such pseudo fatigue with huge doses of coffee, all systems will ultimately fail and a reverse reaction will begin. Caffeine that enters the body instead of vigor will cause drowsiness.
Therefore, for a while, it is urgently necessary to change habits and menus. Strong breakfast coffee should be replaced with fruits and cereals high in carbohydrates, vitamins, and minerals. And from drinks choose black tea with lemon. He invigorates no less and gives strength throughout the day.
Everyone has their own norm
How much coffee do you need to feel great, to be vigorous and healthy? Someone just needs to feel the aroma to cheer up, and the other person wants to sleep from coffee. Why such a reaction?
We are all different. And the reaction of the body is individual for everyone. When considering the effects of coffee on the body, the health benefits and harms depend on the caffeine metabolism rate. Those who have it high need a constant supplement of a refreshment drink, sometimes up to 5-6 cups daily. Otherwise, drowsiness and lethargy occurs. 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 I feel sleepy from coffee (why we already know this), but this does not always happen. It all depends on the preferences and characteristics of the body. With proper intake, the drink gives a charge of vivacity and good mood.
