Are caffeine energy drinks bad for you?
The FDA has received numerous reports linking energy drink consumption to deaths and serious adverse reactions, including elevated blood pressure, convulsions, and heart rhythm abnormalities. Many of these cases have resulted in hospitalizations. Reports underscore that energy drinks have deleterious effects on a broad spectrum of bodily organs, culminating in mild adversities such as anxiety, gastrointestinal disturbances, dehydration, nervousness, and tachycardia, along with more severe outcomes like rhabdomyolysis, acute kidney injury (AKI), ventricular .The FDA estimates toxic effects, like seizures, can be observed with rapid consumption of around 1,200 milligrams of caffeine, or less than 1/2 teaspoon of pure caffeine. Pure and highly concentrated caffeine products can have serious health consequences, including death.It’s likely that caffeine protects the brain when consumed moderately but potentially harms it when consumed excessively, says Dr. Hensrud. Finally, most people don’t consume straight shots of caffeine. Instead, the chemical comes embedded in a food or beverage, including cola, energy drinks, coffee, tea and chocolate.It immediately slows down transmission speed of signals in the brain, leading to the feeling of brain fog and a drop in brain endurance. In the long-term, chronic brain inflammation will lead to sustained microglial activation and eventually neuronal death. Energy drinks can also impact one’s short-term memory.In one study, echoencephalography (EEG) demonstrated that caffeine intake from energy drinks increased left frontal activation to a greater extent than the right frontal lobe, thus suggesting that energy drinks mimic the effect of dopamine on striatopallidal neurons to reduce fatigue.
What happens when you drink too much energy drinks?
Symptoms include anxiety, insomnia, gastrointestinal upset, muscle twitching, restlessness, and periods of inexhaustibility. In addition, High caffeine intake is associated with acute and chronic daily headaches by stimulating a pro-nociceptive state of cortical hyperexcitability.

Caffeine usage surpassing 400 mg has been shown to increase the likelihood for anxiety and panic attacks in a population.By stimulating the nervous system, people feel energized, but also feel anxious and irritated, get headaches, and will have interrupted sleep, even at small doses. Chronic caffeine intake has the same effects but also affects the cardiovascular system, leading to increased blood pressure.Caffeine has been linked to the aggravation and maintenance of anxiety disorders, and the initiation of panic or anxiety attacks in those who are already predisposed to such phenomena. Caffeine usage surpassing 400 mg has been shown to increase the likelihood for anxiety and panic attacks in a population.Anxiety and unsafe behaviors—especially in adolescents—are associated with energy drink use.

Energy drinks are associated with an increased risk of mental health issues among children and young people, including anxiety, stress, depression, and suicidal thoughts, a new study has found.Energy drinks, with their high-caffeine content, may give you that jump-start, but they appear to have a more negative effect on people’s hearts and blood pressure than other caffeinated beverages, such as coffee or soda, according to a small study published in the Journal of the American Heart Association, covered by .While one energy drink per day is generally safe for most healthy adults, two or more becomes risky, especially if you’re not closely monitoring your total caffeine intake.The issue with energy drinks, especially ones high in caffeine and sugar, is that they can cause your brain to release higher amounts of dopamine, the feel-good hormone ( 17 ). However, the downside is that the more often you consume energy drinks, the less pleasure you experience from the dopamine response.
Is caffeine a drug?
Summary. Caffeine is a drug that stimulates (increases the activity of) your brain and nervous system. Caffeine is found in many drinks such as coffee, tea, soft drinks and energy drinks. Although it has a much milder effect, caffeine has the same addictive qualities as these other drugs. Caffeine temporarily blocks adenosine, a chemical in your body that promotes sleepiness and muscle fatigue, resulting in an energy boost or heightened alertness.Energy drinks are addictive due to their high content of stimulating substances, mainly caffeine and added sugar. The caffeine in such beverages functions as a central nervous system (CNS) stimulant, enhancing alertness and lowering fatigue, resulting in habitual consumption.Caffeine is a stimulant that can make you feel energetic and alert. Alcohol, on the other hand, is a depressant that can make you feel sleepy or less alert than usual.

However, they caution that 100 mg of caffeine taken close to bedtime may affect sleep quality. Although caffeine toxicity is usually characterized by neurologic symptoms,3 such as confusion and tremors, severe toxicity can further cause organ dysfunction, specifically cardiac arrhythmias and cardiorespiratory failure.The FDA estimates toxic effects, like seizures, can be observed with rapid consumption of around 1,200 milligrams of caffeine, or less than 1/2 teaspoon of pure caffeine. Pure and highly concentrated caffeine products can have serious health consequences, including death.There is a three-way tie for the top of the caffeine list – Celcius Heat, Bang and Rockstar Xdurance, all with 300 mg of caffeine per can.
