Quickly recharging your energy and almost instantly getting a powerful boost of energy for several hours is quite convenient and even tempting. However, every action must have a downside, and it’s not always as rosy and attractive.

We have been hearing for many years about the miraculous effects of energy drinks on various areas of perception, but we have not thought at all about what consequences these “magic” drinks can bestow on our body.

Origin and original composition of energy drinks

Even in ancient times, there was information about the miraculous effects of various elixirs and herbal infusions, helping to stay awake for a long time and feel full of strength. At the same time, the harm from such drinks was minimal - largely due to the natural origin and environmental friendliness of the components.

The first energy composition appeared in England and was launched into mass sale under the name “Lukozade”. The second producing country was Japan, which is now rightfully considered the leader in the production of such products.

Modern energy drinks have appeared relatively recently, and all manufacturers of original products of this type unanimously speak about the complete safety of their creations. At the same time, it is worth considering how individual components can be harmless or, conversely, make a negative contribution to the life of various organs.

Energy Drink Ingredients

Components of energy drinks from different manufacturers almost the same, at least the main ones are the same. The main components of the energy elixirs of our time are:

• Taurine. The synthesis of the substance occurs in the gall bladder, participating in a number of metabolic processes and improving cell nutrition. It is considered harmless in small quantities, but not in those in which it can be used as part of modern energy drinks.
• Caffeine. Can be replaced by theine or mateine. Mainly serves to increase mental and physical performance, enhancing reaction and memory. At the same time, the pulse rate increases, the level of blood pressure (BP) increases, and in many cases arrhythmia may develop.
• Theobromine. Quite a strong stimulant.
• Melatonin. Provides the level of vital functions, activity, and circadian rhythm of a person.
• Vitamins and glucose.

It can also be noted that energy drinks are highly carbonated drinks containing carbonic acid. Thanks to it, the components included in the drinks are absorbed much faster, and the desired effect is achieved quite quickly. By law, manufacturers indicate on the labels or containers the exact composition of the drink they produce, as well as the safe amount of the product for consumption.

To drink or not to drink? That is the question!

The benefits of drinking energy drinks seem to be significant, but at the same time, the effect is temporary - with a duration depending on the specific product and its composition. The most harmless and even useful components of drinks are glucose and various vitamins, as well as carbohydrates. Even many famous athletes do not hide their preferences for energy drinks.

But constant research tirelessly confirms the negative, extremely negative impact on individual areas and the body as a whole. The excited, often euphoric state of a person after drinking energy drinks is replaced by even greater fatigue, insomnia and nervous irritation.

A number of proven factors are considered clear indicators that an energy drink is extremely harmful. The main ones include:

1. Rapid increase in blood pressure and blood sugar levels.
2. The effect is addictive and can significantly deplete the nervous system.
3. The presence of multiple side effects in case of overdose, of which the most unpleasant are depression, cardiac dysfunction, and psychomotor overexcitation.
4. High calorie drink.

The dark side of the coin - why are energy drinks harmful?

It is also worth considering the point that many representatives of modern youth simply do not pay attention to when they consume energy drinks excessively. It is highly undesirable to mix energy drinks with alcohol or drinks containing caffeine. Such abuse can lead to the most unpleasant consequences, so you need to think about what and at what time you can use the energy drink.

In addition, energy drinks in any form or quantity are absolutely contraindicated for certain groups of people: pregnant women, teenagers, children, the elderly, as well as people susceptible to various heart or chronic diseases. You should not drink energy drinks while undergoing medical intervention or taking medications.

Among the lesser evils that can result from the abuse of energy drinks are disruption of the acid-base balance in the mouth and destruction of tooth enamel. And in some cases, the occurrence of allergic reactions could be observed.

Therefore, the debate about whether modern energy drinks are beneficial or harmful continues to this day, without ever coming to a common denominator. At the same time, it should be noted unequivocally and irrevocably: energy drinks can only be consumed in small doses, not too often, and only for those people who have no obvious contraindications.

An energy drink is an energy drink that stimulates brain activity and invigorates. With increasing tension and lack of energy, a person resorts to additional stimulants to strengthen the body. What is the harm from energy drinks? Harm from energy drinks is caused by the components they contain.

How does the composition affect the human body?

Composition of energy drinks:

1. . Stimulates mental and physical activity. Increases heart rate and stimulates the nervous system. How much caffeine is in energy drinks? The indicator ranges from 80 to 150 grams, the same content in a cup of coffee.
2. Sugar, . Improves brain concentration.
3. Taurine. Helps concentrate, improves performance and promotes the absorption of minerals. Included in most vitamins for children and adults.
4. L-carnitine. Accelerates metabolic processes and has a positive effect on the condition of the heart and blood vessels.
5. Glucuronolactone. Cleanses the gastrointestinal tract and removes toxins from the body.
6. Guarana and ginseng root. It is invigorating, but useful taking into account proper dosing; if the drink is abused, sleep is disturbed.
7. Matein. Used to combat obesity and reduce appetite.
8. B vitamins stabilize the nervous system.

Energy drinks contain useful elements, but does this mean that you can drink them all the time? Or do energy drinks only cause harm?

How do energy drinks work?

How long does it take for an energy drink to take effect? After drinking a bottle of cocktail, the invigorating effect appears within ten minutes. It comes on faster if you drink it in a hungry state.

How long does the energy drink last? The duration is four hours, and after that the opposite state is observed: nervous excitability and loss of strength.

Video: harm from energy drinks (shock)

The problem of the harm of energy drinks is becoming more and more discussed in the scientific community and in the press, which is due to their incredible popularity, the rapid proliferation of products on store shelves and the real facts of the serious consequences of consumption, especially by the younger generation.

Someone will object: " Hey! they are no more dangerous or harmful than a regular cup of coffee!"

Most fire drinks actually contain NOT more caffeine than a cup of coffee from Starbucks.

However, the question is not only about caffeine, but also about other ingredients, or rather their combinations.

Below we provide scientific facts about the dangers of energy drinks, as well as expert opinions on this matter.

Reviews from experts about the dangers of energy drinks

The following expert opinions are taken from the CNN website from a material devoted to journalists’ research into the problem of harm from energy drinks:

"Over the years of research, we have become closer to understanding the dangers of energy drinks to health“says Dr. John Higgins, a sports cardiologist at McGregor Medical School.

To which the American Beverage Association counters: "...we are confident in their absolute harmlessness, since the ingredients in their composition are also contained in other products and are natural, and their safety has been thoroughly researched. ”

Energy drink manufacturers: " ingredients in their composition are also found in other products and their safety has been thoroughly researched"

The benefits, harms and uselessness of a product are determined by what is inside it.

Most energy drinks contain a considerable dose and Sahara; Also B vitamins; legal stimulants such as guarana(plant from the Amazon forests); taurine- an amino acid that is naturally found in fish and meat; a popular fat burner is a substance, one of the functions of which in the body is to convert fats into energy (scientific research, by the way, has shown the effectiveness of L-carnitine for weight loss).

“The reason for concern is that all these vitamins, amino acids and herbal ingredients are contained in them in large quantities than in its natural form in food or plants, and also in the fact that their combination with caffeine significantly enhances the stimulating effect“says Katherine Zeratsky, a registered dietitian at Mayo Clinic.

Dr. Higgins, who has been studying the harm of energy drinks to the body for a long time, agrees with her:

“Regarding caffeine, sugar and stimulants, more thorough research is needed what negative consequences their combined action can lead to.It's something like a black hole...we know very little about how the combination of the two works”.

Dr. Higgins: " The ingredients in energy drinks and how they work in combination is something of a black hole... we know very little about how their combination works"

“People need to be aware of this. For some categories, energy drinks can be very dangerous; speech comes first about teenagers under 18 years of age, pregnant women, those who are sensitive to caffeine or who do not drink caffeine regularly, or are taking certain medications.”

Representatives of the American Beverage Association object:

“People all over the world have been drinking energy drinks for 25 years and no one has ever been harmed...all of their ingredients are found in many other natural products.”

When it comes to the dangers of energy drinks, the quantity is of enormous importance and it is their uncontrolled consumption in too large a volume that leads to dangerous consequences. Remember this thought.

How much is too much?

The main reason for the dangerous side effects of energy tonics is their consumption in too large quantities

If you do not fully understand what energy drinks or energy drinks are in sports nutrition, then first study our material

13 facts about the harm of energy drinks based on scientific data

The side effects of energy drinks have much in common with them, but they also have their own specifics.

1 Harm to the heart from energy drinks

You've probably noticed that after taking energy drinks, your heart starts beating faster.

The effect of energy drinks is manifested in abnormal heart rate, and distortion of the cardiogram(duration of intervals of contraction and relaxation of individual regions of the heart), both in adolescents and adults 3,4.

How dangerous is this?

One scientific report cites facts that from 2009 to 2011, there were about 5,000 cases of emergency room visits due to serious harm to the heart after taking energy drinks 2. 51% of victims are teenagers under 18 years of age (US statistics).

Almost all energy drinks contain caffeine, a powerful stimulant of the nervous system.

Caffeine has a lethal dose. It is individual for each person.

It can occur even after two cans of energy drinks. This applies to those who have heart problems.

"Heart palpitations can pose a real and serious risk, as energy drinks not only increase stress levels, heart rate and blood pressure, but also make the blood more viscous“- says the same Dr. Higgins.

“Blood viscosity increases, probably due to the specific combined action of caffeine and taurine: the amino acid taurine is known for its ability to remove fluids from the body and with it some minerals.”

“Guarana, which can often be found in energy drinks, is a natural source of caffeine: adding it further increases its concentration.”

Over 2 years in the United States, more than 5,000 cases of emergency room hospitalization were recorded due to serious harm to the heart from energy drinks.

Real examples

“There are several known cases where, after consuming more than one can of energy drinks, cardiac arrest occurred 14,15: in the first of them, the young man was saved, in the second, death occurred. When scientists analyzed the autopsy results and blood tests, they found no other reasons other than very high levels of caffeine and taurine in the blood.”

“In another case, a 28-year-old man was hospitalized with cardiac arrest after drinking 8 cans of energy drink. According to doctors, the arteries of his heart were completely closed. After rehabilitation, all tests showed that the only thing that was wrong with him was very high levels of caffeine and taurine in the blood 16.”

“One of the side effects of caffeine combined with other ingredients in energy drinks may impair the function of the arteries, namely their ability to relax and dilate, especially during exercise.. During exercise, arteries relax and widen to allow more blood to pass through..”

During the autopsy after the death of the young man, doctors did not find any other reasons other than very high levels of insulin and taurine in the blood. The same result during the rehabilitation of a young man after a complete cardiac arrest

2 Headaches and migraines

Drinking large doses of energy drinks can lead to severe headaches.

Moreover, it seems to influence the frequency of headaches not the dosage size, but its sudden change (they drank and drank, got used to it, then suddenly stopped).

CHINESE STUDY

Findings from the world's largest study of the links between diet and health

Results of the largest study of the relationship between nutrition and health, consumption animal protein and... cancer

"Book No. 1 on nutrition, which I advise absolutely everyone to read, especially athletes. Decades of research by a world-famous scientist reveal shocking facts about the relationship between consumption animal protein and... cancer"

Andrey Kristov,
founder of the site

This phenomenon is called “caffeine withdrawal syndrome” and is very similar in essence to a hangover after alcohol.

3 State of unreasonable anxiety, fear and stress

A state of internal anxiety is a characteristic psychological side effect of caffeine.

Also, drinking energy drinks can cause stress. One of the reasons is hormonal: scientists have found that their consumption increases the level of the stress hormone norepinephrine by 74% 9 .

4 Insomnia

One of the reasons why energy drinks are taken is to combat sleep. They do this well. The problem, however, is that even after you stop using it, the effects may continue.

The lack of healthy, full sleep impairs performance, especially mental activity.

This is especially important for drivers to keep in mind, for example, since a sleepless night on energy drinks today can lead to an accident tomorrow or the day after tomorrow.

5 Type 2 diabetes

According to scientific research those who drink 1-2 sugary drinks per day have 26% greater risk of developing type 2 diabetes 5 .

The reason for this is a kind of “wear and tear” of the pancreatic gland, which is responsible for the secretion of insulin, the function of which is to control blood sugar levels.

Chronic "sweetening" of the body over time can lead to development of insulin resistance, more commonly known as type 2 diabetes.

Regular appointment Sugary energy drinks increase the risk of developing diabetes by ~30%

6 Drug interactions

Ingredients in energy drinks can interact with medications, most commonly antidepressants.

7 Addiction

Those who regularly consume caffeine may become addicted to it. This also applies to energy drinks.

Addiction manifests itself in the lack of internal motivation to do something without taking a dose.

An indirect side effect of this condition is the creation of a serious financial hole in the wallet due to the need to buy several cans of energy drinks every day.

8 Formation of bad habits and socially dangerous behavior

According to scientific research, regular intake of energy drinks provokes:

• formation of addiction to cigarettes, drugs and alcohol,
• makes behavior more aggressive, increases the tendency to sort things out with fists rather than tongues,
• encourages other forms of dangerous behavior in the form of unprotected sex, a penchant for extreme sports and other forms of risk 6 .

Everyone knows how this can end.

9 Shaking hands and nervousness

Consequences of using energy drinks can be uncontrollable shaking of hands and emotional instability 7 .

As a result, it is difficult to perform certain types of work that require fine motor skills, and emotional temper is harmful to the person himself and the society around him.

10 Vomiting

Drinking too many energy drinks at once can cause vomiting.

The harm of this action is not limited only to the unpleasant characteristic aftertaste; When vomiting, the body becomes dehydrated, and acids from the stomach destroy tooth enamel. This is especially dangerous if it happens regularly.

11 Allergies

Numerous overt and hidden ingredients in energy drinks can cause allergic reaction, ranging from simple itching to obstruction of the respiratory tract.

12 High blood pressure

For healthy people, this change is not a big problem. And for those whose blood pressure regularly fluctuates, drinking too much energy drinks can lead to a significant increase in the risk of heart attack 8 .

When you compare the negative blood pressure effects of energy drinks and other caffeinated drinks with equivalent caffeine content (such as coffee or tea), the harm of energy drinks is much greater 10 .

This fact indicates that energy drinks exactly the combination of ingredients enhances the negative impact.

The effect of energy drinks on blood pressure is significantly greater than that of coffee or tea with an equivalent dose of caffeine

13 Vitamin B3 overdose

B vitamins, along with caffeine and sugar, are added to almost all energy tonics.

They contain vitamin B3 (niacin) in small doses, which may even have health benefits.

However, if, in addition to energy drinks, other nutritional supplements or multivitamin complexes are taken, the risk of an overdose of vitamin B3 increases.

Symptoms of vitamin B3 11 overdose:

• skin redness;
• dizziness;
• fast heart rate;
• vomit;
• gout;
• diarrhea.

An overdose of vitamin B3 can even cause the development non-viral hepatitis. One case was reported in a man who drank 5-6 cans of energy drink every day for three weeks 13 .

Regular consumption of energy drinks can lead to an overdose of vitamin B3 and even the development of hepatitis

Summary of the dangers of energy drinks

Too much of any food or substance can be harmful to the body. This is true for energy drinks as well.

Energy drinks contain mainly natural substances, which, when consumed in moderation, should not pose serious harm to health. And they might even be useful. This applies to caffeine, L-carnitine, and B vitamins.

At the same time, caffeine and guarana are stimulants of the nervous system and should be treated with due respect.

To avoid the negative consequences of energy drinks, it is important to understand which ingredients are harmful and avoid overdosing on them. We are talking primarily about caffeine, sugar, guarana (a source of caffeine), vitamin B3 (niacin).

Consider their intake from other products and food additives and do not exceed recommended amounts.

The content of the article:

Energetic drinks is a common product designed to increase a person’s physical and mental activity. Growing up in Lately The popularity of energy drinks is justified by their good taste and invigorating effect. However, upon closer study of their impact, it became clear that there is a flip side to the coin. Read in this article about the benefits and harms of ready-made tonic drinks and how to use them correctly so as not to harm your health.

Description and composition of energy drinks

In the current conditions of an accelerated pace of life, quite often we have to struggle with fatigue, lethargy, and low performance. One of the simplest and most popular ways to cheer up is the use of tonic substances in ready-made products - energy drinks.

Great demand for this type products justifies their diversity in the modern market. They differ in the effectiveness of their impact and the duration of this invigorating effect, which fully depend on what ingredients are used in production.

Any energy drink has a rich chemical composition, which includes various tonic substances in different combinations and concentration. Let us describe commonly used options for tonic and stimulating elements and their effect, which determines the effect of energy drinks on the body:

• Carbonic acid. With its help, the processes of assimilation of all product components entering the body are activated. Not only the rate of absorption from the gastrointestinal tract increases, but also distribution throughout the body. It is with its help that drinks become highly carbonated.
• Caffeine. A well-known invigorating component. When consumed in certain doses, it affects the cerebral cortex, stimulating excitation processes. It helps fight drowsiness, fatigue, because... increases both physical and mental activity. It is an antidepressant, increases stress resistance and adaptive abilities of the body. It also stimulates processes related to intimate life- improves spermatogenesis and potency in men and helps prolong sexual activity in women with age due to increased sensitivity. Pure caffeine is the most effective, but it is fraught with the danger of addiction.
• Theine, mateine, guaranine. These are other names for caffeine. The difference is justified by the source of receipt. Teine - from tea, matein - from Paraguayan holly, guaranine - from guarana. The beneficial properties are generally similar, but may have some differences, because each of the listed plants that are a source of caffeine has a different chemical composition from coffee beans.
• Vitamins. They are found in energy drinks everywhere. They are very valuable for the course of all vital processes. Most often these are ascorbic, nicotinic, folic acids, pyridoxine and calcium pantothenate.
• Theobromine. Under the influence of certain chemical substances can be converted to caffeine. It has a similar effect on the body. It is extracted from cocoa seeds by freeing them from fat. At acceptable doses, it prevents the formation of blood clots and neutralizes spasms of the vascular system. Able to accelerate urine excretion. It lifts your mood and significantly improves your well-being. At high doses it can cause intoxication.
• Theophylline. Its structure is similar to caffeine and theobromine. Relaxes smooth muscles, normalizes respiratory function, stimulates the activity of the heart and nervous system, and reduces vascular tone. Dangerous in high concentrations. It is a drug, therefore, when taking tablets, the level of its concentration in the blood serum should always be monitored. Concentrations in energy drinks should be limited.
• Glucose. It is the most important source of energy for the body. Stimulates the functioning of the nervous system and the restoration of muscle tissue. Increases stress resistance and improves mood. Regulates the functioning of blood vessels and the heart. Increases performance. Improves thought processes. Dangerous if consumed frequently in large quantities.
• Sucrose. When ingested, it serves as a source of glucose, the beneficial properties of which are described above.
• Taurine. Transformed in the liver, it is part of bile and promotes the emulsification of fats. Takes part in lipid metabolism. Significantly improves metabolic and energy processes. To some extent, it neutralizes seizures by inhibiting the transmission of nerve impulses. For therapeutic purposes, its use is indicated in the presence of cardiovascular insufficiency. It is a common dietary supplement in the food industry, therefore it is included in juices, energy drinks, dry milk formulas for children under one year old, as well as in animal feed.
• Ginseng. It is a medicinal plant. Due to the presence in its composition of vitamins, various micro- and macroelements, as well as other useful substances and compounds, ginseng is a general tonic that can increase the body’s adaptive capabilities. Its functions include stimulating the nervous system, increasing blood pressure, and improving mental and physical performance. It clears the blood of cholesterol and lowers glucose levels.
• Alcohol. Not present in all energy drinks. It enhances the effect of other ingredients. Improves mood and physical activity. But if used incorrectly, it has an extremely detrimental effect on health.

The average caloric content of energy drinks, depending on the composition, ranges from 49-56 kcal. They do not contain proteins or fats. And the carbohydrate content reaches 95%.

In some countries, for example France, Denmark, Norway, energy drinks cannot be seen in the public domain, because... This category of goods belongs to dietary supplements, which can only be purchased at pharmacies.

The situation in Russia is completely different - any, even the smallest assortment grocery store offers energy drinks. Restrictions in our country are related to the composition and labeling of the product, as well as the rules for their sale. Thus, it is prohibited to include more than 2 stimulating components in the composition. The text on the can must contain information about restrictions on use. Geographically, such drinks cannot be sold in educational institutions.

The effect of energy drinks on the body

The individual effect of each specific energy drink on the body depends on its composition. Although it differs only slightly.

The main purpose of energy drinks is to quickly and temporarily overcome fatigue and drowsiness, improve physical and mental activity, i.e. increase efficiency and attentiveness. We will tell you how and due to what this happens, describing the mechanism of action.

After drinking energy drinks, the human body goes through several stages of exposure to active components:

1. Lifting stage. Once in the gastrointestinal tract, all ingredients are quickly absorbed into the blood and begin vigorous stimulating activity. A person feels a surge of strength, vigor, becomes more active and proactive. Part of the energy for such activation is taken from the drink itself. In this case, the basis is glucose. However, its concentration is not high enough to cover all the required reserves. At this stage, the absorption of glucose increases significantly, processes associated with the breakdown of fats are normalized and sometimes accelerated. The heart muscle is stimulated, causing the heart rate to increase. Blood pressure rises. Some components have an irritating effect on the kidney epithelium, which causes an increase in the amount of urine produced. Along with this, cell nutrition improves with sufficient simultaneous consumption. healthy products nutrition.
2. Wakeful stage. During this several-hour period, the stimulating effect is largely provided by internal reserves, i.e. reserves accumulated by the body. A person maintains a high degree of efficiency and activity, does not feel tired or want to fall asleep.
3. Stage of loss of strength. Studies have shown that consumption internal energy sometimes so great that it can lead to exhaustion of the body. So, after consuming 1-2 cans of the product, after 3-5 hours a person may feel increased weakness and fatigue. Drinking an additional portion of the drink will not always lead to a second rise, because... The body's resources are not unlimited. This, on the contrary, leads to even greater exhaustion and an increased likelihood of developing severe side effects.

In the long term, such artificial stimulation of the nervous system stimulates increased production of endorphin, the hormone of joy. With the systematic use of energy drinks, the brain gets used to it and gradually reduces its synthesizing capabilities, hoping for the next supply of the drink’s components. Regular consumption of such energy cocktails causes the adrenal glands to reduce the rate of adrenaline production. Without a new dose of a complex stimulating product, its deficiency appears. It is replaced by the production of a stress hormone, which ultimately leads to exhaustion of the nervous system.

Thus, the essence of taking energy drinks is the same - they do not replenish energy, but use the body’s hidden resources. And the more energy drinks you drink, the more exhausted your body becomes.

It is noteworthy that drinks containing vitamins can be considered the most useful, and those containing alcohol are the most dangerous. The mechanism of action of low-alcohol energy drinks is slightly different from non-alcoholic ones, because... the effect of stimulating components and the effect of alcohol have opposite sides. Therefore, when they are combined, the effect is not only invigorating.

Due to the high carbon dioxide content, alcohol is absorbed more intensively and its effect is significantly enhanced. Along with this, the intoxicating effect remains as hidden as possible. The person does not feel very intoxicated, but the desire to continue drinking both the energy drink itself and alcohol increases. This makes it possible to exceed consumption standards, which is fraught with the occurrence of intoxication and other disturbances in the functioning of the body.

Alcohol, which most often makes up 7% of the total volume, depresses the nervous system to a greater extent, therefore, when drinking such energy drinks, a person often becomes less reasonable and feels unreasonably fearless in the face of emerging dangers. This condition is called “vigilant drunkenness.” Therefore, energy drinks cause particular harm to health when combined with alcohol.

Properties of energy drinks: harm or benefit?

Any energy drink that contains stimulants has both benefits and harms. Therefore, the use of such products cannot be called completely healthy and safe. To protect yourself from a negative result, you should carefully study the nature of the effect, beneficial and dangerous properties, take into account contraindications, and also correctly balance the possible benefits and potential risks.

Beneficial properties of energy drinks

The harm of energy drinks

Energy drinks can cause harm to the body if consumed frequently, when combined with alcohol, if the daily dose is exceeded, or if there are contraindications.

2. Depletion of energy reserves. The lack of nutrients that occurs after their increased use leads to depletion of body cells. In this case, replenishment of strength through healthy sleep and nutrition is required.
3. Metabolic slowdown. The process of activation of metabolism is also replaced by a decline. Digestion worsens, and breakdown products at the cellular level are eliminated worse. Possible liver dysfunction and increased bile synthesis.
4. Negative effects on the cardiovascular system. An increase in blood pressure is fraught with headaches and dizziness. Vessels also suffer.

The harm of energy drinks to the body also manifests itself in addiction, when a state of euphoria from stimulant substances becomes the norm, which leads to a daily need to replenish their reserves by drinking a new portion of energy drink. Thus, the desire to drink a tonic drink again is associated with increased irritability and psychomotor agitation.

Energy: what is it?

An energy drink is a drink that is created using a variety of stimulants and other components: dyes, flavors, vitamins and others. By consuming them, a person influences his central nervous system, thus suppressing fatigue in order to prolong wakefulness, concentrate, and increase mental activity for several more hours.

It would seem that what is bad about these products? After all, they improve performance. But this is only at first glance. The benefits and harms of energy drinks are not equal.

• B vitamins – normalizing the functioning of the nervous system.

The effect of energy drinks on the body

The positive effect of energy drinks on the body occurs only at the beginning of their use, when people feel a replenishment of energy resources and an increase in physical and mental performance. But after euphoria, hyperactivity, and the ability to work under increased load comes exhaustion. After stress or shock, the body turns out to be very worn out and tired.

In addition, such products negatively affect the duration and quality of sleep. It is difficult for a person to fall asleep, he suffers from insomnia, and having dozed off, he sees nightmares and easily wakes up from the slightest noise or irritant. Such rest does not bring joy, does not add strength, does not give a feeling of vigor.

Regular use of such stimulants can cause depression, aggressiveness, suspiciousness, headaches, anger, and often leads to loss of strength, depression, loss of orientation, irritability and even death.

Rules of use

Energy drinks should be drunk in small quantities and infrequently to avoid their negative impact on a person. Do not give to children and adolescents under any circumstances. A growing and developing organism, like no other, is exposed to harmful substances.

You should not drink energy drinks with alcohol to avoid pressure surges and hypertensive crisis.
