Mixing energy drinks with alcohol is a risky combination that leads to a large number of accidents related to poisoning and its consequences. This is stated by researchers from Canada, who back up their words with data from a series of experiments. The main problem here is that, in a large number contained in energy drinks, invigorates. This makes you drink more than usual.
Doctors say that, in addition to the obvious health risks, consuming energy drinks + alcohol even once a week can cause serious and increase heart rate. The charity company Drinkaware does not recommend mixing alcoholic and energy drinks, as consuming such cocktails can be many times more harmful to the body than consuming the same amount of pure alcohol or alcohol combined with juice or syrup.
However, this is not all. In a review of 13 studies published between 1981 and 2016, researchers at the University of Victoria in Canada found a link between energy drinks and alcohol and an increased risk of injury, fights and accidents. The researchers said that they were unable to detect the degree of risk due to the different nature of the studies and the difficulty of comparing the results, but the fact is clear.
When it comes to the question of whether mixing alcohol and energy drinks is harmful, the first thing to keep in mind is the high levels of caffeine in the latter. They usually contain about 80 mg of caffeine per 250 ml can, which is the equivalent of a cup of instant coffee. By comparison, a can contains approximately 32 mg of caffeine, while a can contains approximately 42 mg.
In addition, energy drinks contain, as well as ingredients such as glucuronolactone (DGL) and taurine, sometimes vitamins, minerals and plant substances, which, however, no longer play any role.
Why is caffeine dangerous in general? Doctors remind that it can lead to anxiety and high blood pressure. Pregnant and lactating women are advised not to consume more than 200 mg of caffeine per day. Children should also consume caffeine in moderation: a safe intake of just under 3 mg of caffeine per kg of body weight.
“Usually when you drink alcohol, you end up tired and head home,” Audra Roemer, lead author of the study and at the University of Victoria, told the BBC. "Energy drinks mask this, so people may underestimate how drunk they are."
For the sake of fairness, we note that not all experts talk about the harmful effects of energy drinks on the body. For example, Gavin Partington, CEO of the British Soft Drinks Association, in the same interview states that this moment any special effect of energy drinks on the body in combination with alcohol has not been proven.
That is why the best advice in this case is - and be attentive to your health. Try to have a hearty dinner to keep alcohol to a minimum, avoid canned alcohol, preferring pure foods that are prepared in front of your eyes, and try not to drink alcohol 2-4 hours before bed, so as not to harm its quality.
Over the past five years, alcoholic energy drinks have become 37% more popular. But according to scientists, these drinks are very harmful to health, and their massive consumption can lead to large-scale problems. Is it true?
Alcohol itself causes considerable harm to the human body. This has become a fact long ago and has been scientifically proven more than once. What about regular energy drinks? It cannot be said that they have a detrimental effect on the physical and mental development of people. And there are very few cases of the destructive effect of simple energy tonics on the human body - literally one in ten million. Recently, a new trend has emerged - alcoholic energy cocktails. Doctors and people who understand the principles of these mixes, after research, persistently insist that drinking tonic substances with an ethyl alcohol content of more than 1.2% is not only harmful, but also deadly! Consider how true their statements are.
In order to more correctly and more clearly answer the question: "What is the harm of alcohol-based tonic drinks?", First you need to disassemble their composition.
Usually, the main ingredients of simple energy tonics are the following ingredients:
- caffeine;
- sugar;
- preservative (sodium benzoate);
- colorants and flavorings (guarana extract, taurine, black carrot juice, etc.).
In addition to the main components, alcoholic invigorating mixtures contain ethyl alcohol. Without it, raising the "degree" in the finished drink would be impossible, since this is not beer, and natural fermentation processes do not arise when preparing energotonics. Caffeine and sugar in tonic mixes play the role of energy additives, so you can't go anywhere without them. The addition of a preservative will increase the shelf life of the finished product. Finally, flavors and colors are added to energy drinks for one purpose - to be drinkable. What is the use of such cocktails? Logically speaking, they 
are needed to relieve a drowsy state for a certain period of time in order to raise a person's performance. This may be necessary, for example, if you need to finish some work today at all costs, but you want to sleep unbearably. After all, there are no specialized sleep-relieving pills, although there are some to create.
However, not all consumers of power engineers use these liquids for their intended purpose. The veracity of this statement can be proved by the fact that the main consumers of invigorating drinks are young people - students, adolescents and, oddly enough, schoolchildren who need energy tonics in order to stay awake while hanging out in clubs.
In this regard, the question itself begs itself: "How do energy drinks with alcohol affect the state of people, especially minors?"
Toning liquids with "degree" - action
The basic principle of operation of alcoholic invigorating drinks is set by three substances included in the composition:
- Ethanol.
- Caffeine.
- Sugar.
After entering the stomach, ethanol begins to be absorbed into the bloodstream, causing painfully well-known consequences: relaxation, drowsiness, inertia. In general, an obvious decline in activity.
On the other hand, after caffeine, memory and attention are activated, and an internal reserve of strength awakens. Sugar is high in calories, so it can also be considered a source of energy.
As you can see, the actions are absolutely opposite. It follows from this that after consuming an energy drink with alcohol, a person is unlikely to feel a surge of strength, since the tonic effect of caffeine is "suppressed" by the action of alcohol decay products. It's not that scary yet. After all, lethargy and relaxation after exposure to alcohol will be compensated by the invigorating effect of caffeine. As a result, a person who has consumed an alcoholic energy drink will be drunk, but will not feel it.
Meanwhile, the lack of vigor will force him to drink the second, third and so on cans of dangerous liquid, without thinking about the consequences.
And given the fact that one such "jar of energy" contains 80 mg of caffeine and 30 g of sugar, an overdose of energy drinks with an alcohol content entails a whole list of consequences:
- taking energy tonics in excess of the norm and, as a result, entering a state of so-called vigilant drunkenness, when an excessive load on the psyche makes a person's behavior unpredictable;
- arrhythmia, rapid pulse;
- psychotic disorders associated with an overdose of caffeine;
- weight gain and risk of developing diabetes mellitus due to the increased consumption of sugar;
- exacerbation of chronic diseases against the background of an increased load on internal organs.
By the amount of caffeine and sugar in one bottle of the drink, we can conclude: you cannot drink more than one, in extreme cases, two cans of energy drink per day. Exceeding the daily dose may interfere with normal perception.
It is strictly forbidden to consume alcoholic products of an invigorating nature for schoolchildren and minors. If this is neglected, the consequences of admission can be reflected in the academic performance of adolescents.
What to do in order not to harm yourself with energy tonics?
There are several ways to prevent yourself from harmful effects after taking "charging" drinks with alcohol:
The progressively increasing rate of consumption of tonic drinks with alcohol among frivolous youth leads to mental problems in the younger generation. Several European countries have already said "no" to products containing both alcohol and caffeine. In general, the use of invigorating mixes with a strength of more than 1.2% does not make sense, since a person does not become more cheerful from this.
Drinking alcoholic energy drinks can trick your brain into what the researchers call "vigilant drinking." Of course, it is for this reason that many people combine alcohol and energy drinks, as they can stay awake longer and drink more alcohol.
And although some vigilance is present, the body is still experiencing the effects of alcohol. This means you can drink more without realizing that your judgment, balance, and coordination are suffering.
As such, you are more likely to do things that you would not normally do - get into a fight or cross the road when a car is moving nearby.
Being "vigilantly drunk" means that you are aware but underestimate the amount of alcohol you have drunk and do not feel that alcohol is still affecting your thinking and your ability to respond in an emergency. This creates a false sense of security, which in the meantime is dangerous.
This combination has a similar effect because alcohol and energy drinks have the opposite effect. Alcohol is a depressant that slows down the brain, acts as a sedative in large quantities, when the tongue begins to twist, reflexes slow down, and drowsiness is felt.
On the other hand, the caffeine in energy drinks is a stimulant that promotes the synthesis of adrenaline, making the person feel more alert and alert.
If you mix both drinks, you will feel the stronger effects of caffeine, which masks alcohol-induced disturbances in reaction, memory and other brain processes.
This makes these energy drinks quite dangerous.
Possible consequences
Stimulants based on caffeine and amino acids are harmful to health, prematurely wearing out the body and inhibiting the functioning of all systems. The lesser evil they do is the acidity in the mouth and the destruction of the tooth enamel.
In some cases, after consuming energy cocktails, allergic reactions of varying intensity are observed. With frequent intake and overdose of drinks in a person, the internal reserves of the body are depleted, the nervous system is inhibited, which leads to:
- loss of strength;
- irritability;
- depression;
- death;
- insomnia;
- heart attack;
- increased pressure;
- hyperglycemia;
- diabetes;
- convulsions;
- poisoning with chemicals that make up the product;
- coma, death.
Everything, of course, depends on the individual characteristics of the organism, but the combination of caffeine and ethanol can cause not the most pleasant reaction. Because the burst of energy caused by all stimulants and sugars will be instantly blocked by the effect of the breakdown products of ethyl alcohol.
So, here are the possible consequences:
- Excessive stress on the psyche. As a result, difficult to control behavior.
- Abnormal load on the cardiovascular system, increased frequency of contractions.
- Disorders of the central nervous system. They are provoked by both an excess of caffeine and alcohol.
- The risk of developing diabetes, weight gain.
- Load on all systems of internal organs.
Well, and the most important consequence that not a single person using alcoholic energy drinks can avoid is a long recovery of the body. Everyone knows that the decay products of alcohol are removed for a very long time.
In the event that a person observes the permissible dosage, then there will be no side effects from taking an energy drink. However, most people prefer to mix it with alcohol, so the effect of vivacity is enhanced, and the taste of alcohol is muffled.
However, an energy drink containing alcohol causes a hangover syndrome in the morning - this is nausea, vomiting, dizziness, and general malaise. The results of long-term consumption are the most serious - palpitations, insomnia, overexcitation.
According to studies, in the morning a person does not feel dry mouth, as after drinking a strong drink, but the state of health deteriorates sharply.
Is there any harm to the heart?
In fact, an energy drink is a small bomb, when it explodes, all systems of the body are damaged. Soda contains a ton of useless and harmful substances.
One serving of the drink contains a large dose of caffeine (comparable to 3 cups of coffee), as well as 14 teaspoons of sugar. Doctors are convinced that frequent consumption of energy cocktails causes insomnia, fatigue, problems with the cardiovascular and nervous systems, and a rapid depletion of the body's resources.
The harm from power engineers exceeds the benefit. The American Academy of Pediatrics warns that the components of these drinks have not been tested on children and there is no reason to consider them safe.
In 2010-2011, almost 5 thousand cases of alcohol poisoning were recorded in the United States due to the consumption of energy drinks along with alcohol.
In 2017, an American teenager (Davis Creep) died due to the careless use of a stimulant, who developed severe cardiac arrhythmias.
In the absence of these factors, avoiding the harm from taking energy drinks with alcohol is not so difficult. As the research of scientists shows, the weekly rate of power engineers is no more than 5 jars, the daily rate is 1-2 containers.
Alcoholic drinks are allowed only to adults, both from the point of view of medicine and from the side of the laws of the Russian Federation.
The effect of these drinks is not based on giving strength to the body through natural processes, but on toning it up by stimulating the nervous and cardiovascular systems.
A stressful effect on the internal organs of a person provokes the release of certain substances into the blood, which contributes to the appearance of hyperactivity and euphoria.
The abuse of alcoholic energy drinks or their reception contrary to the considered rules are capable of:
- To bring a person into a constant state of apathy, expressed in a loss of strength, insomnia, increased irritability and the appearance of depression.
- To provoke the development of pathologies of the cardiovascular and nervous systems. In the case of alcohol-based energy drinks, arrhythmias, increased heart rate and mental problems are often observed.
- Increase the risks associated with gaining excess weight, the onset of diabetes mellitus and exacerbation of chronic pathologies of the body.
In an unfavorable combination of circumstances, the considered consequences can provoke the worst thing - a fatal outcome. Is it worth the risk in this way for the sake of temporary vigor? I think no.
In general, an energy drink, even with a single use, is a negative product for any person. An ordinary can of alcoholic beverage contains about 80 milligrams of caffeine and 30-35 grams of sugar.
The influx of these substances into the body's system adversely affects its condition and disrupts natural metabolic processes. Considering this, it is highly undesirable to consume alcoholic energy drinks, even with small frequency.
Any kind of alcoholic energy is harmful to the body, regardless of the fact that alcohol and caffeine are compatible. Indeed, one jar with a volume of 0.5 liters contains in a proportion of 30 grams.
Sugar and 80 milligrams of the main ingredient, plus ethanol. And this leads to the fact that the internal organs begin to work in an enhanced mode.
With regular use, the systems experience an enormous load, which causes a violation in their functionality. In addition, the mental state from abuse of the drink worsens, and a person cannot always control his behavior and actions.
Alkoenergetic over time becomes addictive, which develops into a strong addiction.
In such a situation, a person cannot control, since the taste of alcohol is muffled by flavors and syrups, which are included in the recipe for making a drink.
The most striking example is an energy drink called Jaguar, it contains about 9 percent ethyl alcohol, as well as sodium benzonate. Drinking in large quantities is simply forbidden, when it enters the body, then there are changes in the structure of DNA.
Also, these products lead to the symptoms of Parkinson's disease and provoke the development of cancerous tumors.
In nine European countries, the sale and production of cocktails is strictly prohibited.
Energy drink recipes have evolved over the centuries. In America, not yet discovered by Columbus, the Indians drank a dark liquid from the roasted leaves and bark of the holly tree. The only one side effect such an energy was incessant violent vomiting. The Indians sought salvation from sleep and fatigue in religious drinks made from harmala, ephedra or mushrooms. The most popular energy drinks are still coffee and loose tea.
What you need to know about alcoholic energy drinks, what are they made of and how do they affect the human body?
general characteristics
The first energy stimulants that became available to mankind were tea and coffee. But their power left much to be desired. Demand creates supply, so the market was rapidly flooded with carbonated energy drinks in banks. Their popularity depends on the territorial location and characteristics of the life of each nation. For example, the volume of sales of energy drinks in Russia is growing every year by 10-30%.
The last decade is considered the peak of popularity, although the concept of an invigorating liquid itself is far from new and has been used for a long time.
The first energy drinks
One of the first energy drinks to break into the industrial market was the famous Coca-Cola. The first version of the soda, released in 1886, contained cocaine from coca leaves and caffeine from a tropical cola tree in addition to the standard ingredients. John Stith Pemberton (founder of the Coca-Cola Company) had his own energy fluid recipe. To 1 gallon of syrup (3.8 liters) was added 5 ounces of coca leaves (150 grams). Later, the dosage of the plant was reduced to one tenth, and after 17 years, the component was completely abandoned.
Another regular at the market is Lucozade. The drink first appeared in the English town of Newcastle. In 1927, chemist William Owen created an invigorating remedy for patients with colds or flu. Lucozade was composed of glucose syrup, carbonated liquid, citric / lactic / ascorbic acid, caffeine, sodium bisulfate, sodium benzoate. This is the standard list of ingredients that are included in energy drinks to this day.
In the 1960s, the energy drink market took over Asia. One of the brightest energy drinks of the time was Lipvitan-D, which was produced by a local pharmaceutical company. Since 1962, Lipvitan-D has become the staple drink of hardworking Japanese workers. The miniature bottles, which looked more like a syrup package rather than an energy drink, contained vitamin mixes, taurine and niacin. The liquid really gave a burst of strength, energy, increased concentration. Twenty years after entering the Japanese market, Japan's nightlife has sparkled with new colors. The epochal return of Lipvitan-D's popularity came in the 80s, and the Japanese idle youth became the bulk of buyers.
Popular alcoholic energy drinks
On the post-Soviet market, the first place is occupied by the low-alcohol cocktail "Jaguar". It contains 7%. Previously "Jaguar" was produced with 9 or 5.5% alcohol. The cocktail has become widespread in popular culture and has become a hallmark of a certain group of people who spit on their own health, following fashion trends. By 2017, the cocktail had suddenly disappeared from store shelves, but sales are still ongoing in local kiosks or online stores.
A can of Jaguar contains 150 milligrams of caffeine (equivalent to three cups of instant coffee). The substance provokes nervousness, disrupts sleep, and forms dependence. The cocktail also includes carbon dioxide (increases the rate of absorption of ethyl alcohol, affects the liver), vitamins, 30 grams of sugar (about 6 teaspoons) and flavor. The popularity of the cocktail is due to its relative cheapness and excellent distribution network. Powerful ads from a few years ago still work and make the Jaguar desirable for suggestible teens.
The drug "Alkobarrier"
The list of popular alcoholic energy drinks also includes "Flash", "Strike" and "Gorilla". Their composition and properties are identical to the Jaguar. Only the aromatic fragrances and the concentration of ethyl alcohol in the can may differ.
What is included in the composition of power engineers
Every year, several new products appear on the market, which differ from the previous ones only in the price segment and the appearance of the packaging. Each of them promises inspiration, cheerfulness, an inexhaustible supply of energy, but all drinks are made according to a similar recipe, and their composition is almost identical. According to statistics, there are only 5 basic components for energy drinks: vitamin B3, B6, B12, taurine, caffeine. The only ingredient on the list that actually works and provides the body with energy is caffeine. Scientists have proven this experimentally. During it, some participants drank water with added caffeine, while others - with a complex vitamin composition. As a result, the brain activity, the reaction rate of both groups turned out to be almost identical.
Caffeine is the most popular and used medicinal product in the world. It stimulates the central nervous system, enhances cardiac activity, accelerates the pulse and provokes vasoconstriction. A safe dose of caffeine is 400 milligrams per day. Drinking in excess of the permissible dosage can lead to sleep disturbance, increased heart rate, the development of anxiety, nausea and headache.
1 can of energy drink contains 7 to 200 milligrams of caffeine.
Another important component of alcoholic energy drinks is ethyl alcohol. It has exactly the opposite effect on the body. If caffeine tones a person, then alcohol, on the contrary, stimulates a sedative effect. All systems relax, coordination, memory, reaction speed gradually deteriorate along with well-being.
The effect of ethyl alcohol on the body depends on the concentration and duration of exposure. The use leads to:
- oppression of the functions of the central nervous system;
- stupor, lowering the threshold of sensitivity to pain;
- alcoholic agitation, gradual addiction to a toxic pathogen;
- cirrhosis, gastritis, ulcers, cancer, pathologies of the heart and blood vessels;
- oxidative damage to brain neurons;
- clinical depression;
- of death.
Is it safe to drink alcoholic energy drinks?
The combination of an energy drink and ethyl alcohol can be extremely unpleasant. The exact opposite action of the constituents can trigger a collapse. As soon as the combination of ethanol and caffeine is ingested, the person begins to experience general weakness, decline in activity, drowsiness and apathy to what is happening. The claimed boost of energy from caffeine and sugar will be blocked by the harmful effects of the breakdown products of ethyl alcohol.
Possible consequences:
- excessive load on the psyche, which makes human behavior uncontrollable;
- increased heart rate, excessive stress on the cardiovascular system;
- disorders of the central nervous system (can be triggered by both ethyl alcohol and an excess of caffeine);
- increased risk of developing diabetes mellitus, rapid weight gain, digestive and metabolic disorders;
- increased load on all systems of internal organs;
- exacerbation of chronic pathologies or the development of an acute inflammatory process.
After alcohol tonic liquids can be consumed only after the decay products of ethyl alcohol have been completely removed from human body... Ideally - from 6 to 14 hours, depending on the quantity and quality of the drink. Alcoholic drinks after caffeine can be consumed within 2-4 hours.
For quick and reliable getting rid of alcoholism, our readers advise the drug "Alkobarrier". This natural remedy, which blocks the cravings for alcohol, causing a persistent aversion to alcohol. In addition, the Alkobarrier launches regenerative processes in the organs, which alcohol began to destroy. The tool has no contraindications, the effectiveness and safety of the drug has been proven by clinical studies at the Research Institute of Narcology.
The legislative framework
The main question concerning power engineers, which are discussed by deputies in government bodies and schoolchildren - is it possible for minors to drink invigorating drinks? A product that does not contain alcohol can be sold to a minor. If a retail chain or a local store refuses to sell a non-alcoholic energy drink, for example, to a 16-year-old guy, then this indicates the seller's illiteracy. But the laws for the sale of liquids with caffeine, taurine and vitamins may differ geographically. For example, in the Moscow region, it is prohibited to sell tonic drinks to minors (regardless of the presence / absence of ethyl alcohol in the composition).
Energy drinks do not include coffee, tea, liquids based on tea or coffee extracts, the concentration of caffeine in which does not exceed 0.151 mg / cc. cm.
The situation is different with alcoholic energy drinks. They are equated with alcoholic beverages, which are prohibited from selling to minors. In each country, the law banning alcohol-containing products has some peculiarities. For example, in the USA it is permissible to drink alcohol from the age of 21, in Europe - from 18, in Asia - from 16-14, and in some African countries there is no such ban at all.
The laws that regulate the circulation of alcohol may differ even within one country (for example, by region). In most cases, energy drinks are equated with alcoholic drinks, and their sale is allowed only upon reaching the Legal drinking age. Familiarize yourself with the legal framework of the country in which you plan to make a purchase, and act in accordance with the established rules. Be aware of the potential dangers of alcoholic energy drinks and stay healthy.
There are many substances with psychostimulant properties, but the most popular are caffeine and ethyl alcohol. What happens if you mix an energy drink or alcohol with coffee?
Energy drinks - composition
Now popular in certain circles, the so-called energy drinks or energy drinks, as a rule, have a similar chemical composition... 100 percent of these liquids contain caffeine, in very high concentrations. Some manufacturers add theobromine (a psychostimulant found in cocoa beans), L-carnitine, and simple carbohydrates in high concentrations.
The effect of caffeine on the human body is quite specific. Under its influence, the electrical activity of the brain is stimulated, which activates excitation reactions, suppresses inhibition processes, accelerates the transmission of an electrical impulse, activates many nerve centers (respiration and heartbeat), accelerates the reactions of biosynthesis of neurotransmitters.
Simply put, caffeine is a potent central nervous system stimulant. The consequence of this is the suppression of sleep, increased performance, increased breathing and heart rate, increased physical endurance, increased (moderate) mental abilities, increased blood pressure, stimulation of concentration.
The effect of theobromine is similar, although somewhat less pronounced. This substance helps to improve mood and well-being, since it predominantly enhances the biosynthetic reactions of the so-called happiness hormones - endorphins and enkephalins.
High concentrations simple carbohydrates are added with only one purpose - to support the body's energy metabolism, charging it with glucose. Of course, after drinking such a drink, the concentration of sugars in the blood increases sharply, which contributes to an increase in a person's physical endurance.
The effect of an energetic on the body
The body's first reaction to an energy drink is quite predictable. Unmotivated vigor and endurance appear, as mentioned above. However, it should be borne in mind that the body's resources are not unlimited, which means that sooner or later the inhibition processes, despite any stimulation, will spread to all parts of the central nervous system.
Energy drink with coffee
The psychostimulating effect of coffee on the human body is naturally dictated by caffeine. If you consume coffee beans, then the caffeine will only be of natural origin. Instant coffee, in most cases, is a product of the chemical industry.
It is quite obvious that when consumed together, the stimulating effects of the energy drink and coffee will add up, which often leads to an overdose of caffeine.
In such cases, one should expect the appearance of such symptoms: insomnia, unmotivated anxiety, palpitations, facial flushing, fever, tremors of the extremities, nausea, diarrhea, high blood pressure.
In more severe cases, the development of hallucinations and delusions, loss of consciousness, pathological types of breathing, convulsions, respiratory arrest and cardiac activity should be expected, which will result in a lethal outcome.
Energy drink with alcohol
If an energy drink is mixed with alcohol, then this combination can affect the body in different ways. It all depends on the dosages of a particular component. Ethyl alcohol, like caffeine, is a psychostimulant (in small dosages). High doses of ethanol act in the opposite way - they cause a strong inhibition of the activity of the central nervous system.
In small concentrations, as in the previous case, the effects of the drinks will add up, which will be expressed in the appearance of strong euphoria, insomnia, talkativeness, palpitations, and so on.
With a combination of high dosages of alcohol and low concentrations of energy drinks, their effect will be multidirectional, but this should not be considered a blessing, since in this state a person can consume more ethyl alcohol, which can lead to severe poisoning or even death.
Coffee with alcohol
Coffee with cognac is undoubtedly a classic of the genre. This combination is familiar to everyone without exception (those who have reached the age of 21, of course). In small quantities, within the framework of cultural consumption, it is rather a blessing that allows you to quickly warm up or relax a little.
However, if you consume coffee after significant libations, the benefits will no longer be discussed. Also, as in the case of energy drinks, a false sense of sobriety may appear, which will further aggravate the condition with a few glasses of alcoholic drink, or vice versa, get behind the wheel and get into some other potentially dangerous situation.
conclusions
If we talk about alcoholic beverages and natural coffee, then it is quite obvious that in small quantities, both of them, together or separately, will not cause harm. However, with an increase in the number of at least one of them, the situation changes dramatically.
As for energy drinks, it is better to bypass them, since the caffeine in them is synthetic, and its concentration is such that it is sometimes difficult for even a young body to endure such a caffeine blow.
