How Do Energy Drinks Work?

Energy drinks typically contain high amounts of stimulants, such as caffeine.

The amount of caffeine in these drinks is typically high, resulting in an increased amount of energy and attention, but for some, can also lead to side effects like irritability and anxiety. Most energy drinks also contain other ingredients that have not been thoroughly studied, resulting in an unknown impact on the user.


Caffeine And Other Stimulants

An important ingredient present in many energy drinks is caffeine. Caffeine is a central nervous system (CNS) stimulant and can result in the side effects of increased heart rate and blood pressure.

A CNS stimulant directly affects the brain, which can cause side effects such as increased mental alertness, focus, and energy. This occurs as a result of caffeine increasing cortisol in the body. Cortisol is a stress hormone, which is why for some, caffeine can increase feelings of anxiety or jitters.

Consuming excessive amounts of caffeine can also result in restlessness, which is also a common side effect of energy drinks. Energy-drink-related emergency room visits have also been associated with side effects like irregular heartbeat and seizures.

What Are The Side Effects Of Energy Drinks?

As the popularity of energy drinks continues to grow, so do the number of side effects associated with their use. Energy drinks are not regulated and many companies do not test their drinks in clinical trials the same way other beverages are, resulting in some side effects not being immediately evident.

While side effects of energy drinks might be minimal for young adults, others can experience severe side effects with associated health risks.


Heart Palpitations

Energy drinks have been shown to increase heart rate and cause palpitations or rapid heartbeat. This usually occurs in people who drink a lot of caffeine and are otherwise healthy.

Caffeine can also trigger palpitations and heart arrhythmia in people with heart conditions like atrial fibrillation. If you experience palpitations while drinking energy drinks, reduce the amount you consume until your palpitations subside.

Irritability And Anxiety

Several studies have linked energy drink consumption to side effects like heart palpitations, irritability, and anxiety.

People who suffer from anxiety or irritability can experience an increase in both due to caffeine in energy drinks. If you have anxiety or irritability issues, talk to your doctor about ways to lessen the severity of the symptoms.

Caffeine is a stimulant, making you feel more awake, but it also increases cortisol, circulating epinephrine (Epi) and norepinephrine (NE), elevate free fatty acids (FFAs), and alter heart rate, blood pressure (BP), and to alter breathing patterns in humans. People who suffer from anxiety or irritability issues are encouraged to keep energy drinks in moderation.


Dizziness And Nausea

People who suffer from dizziness or nausea when consuming caffeine are encouraged to limit their intake. Caffeine is a central nervous system stimulant, and it can act as a diuretic and cause you to become dehydrated. By drinking energy drinks, you increase your risk of becoming dehydrated without realizing it.

Liver Impairment And Hepatitis

While the liver is often damaged when consuming too much alcohol, some energy drinks can have the same effect on the liver. 

There are currently no regulations or standards for the amount of caffeine in energy drinks. This means that caffeine in an energy drink can vary significantly from one beverage to another.

As a result, it isn't easy to know what is too much caffeine for you. Some people can drink small amounts of caffeine and not experience adverse side effects, while others can suffer severe side effects.

 It is important to read the label and to understand ahead of consuming a drink, how much caffeine and other ingredients are present before consuming them.

Excessive Energy

Regular energy drink consumers sometimes have an “energy high” after drinking an energy drink. This can last anywhere from a few hours to a few days as your body removes it from your system. 

Energy drinks are not regulated the same way beverages like coffee are. Because they are not regulated, the caffeine level in energy drinks can vary greatly. While one beverage might contain a low amount of caffeine, another could have a high amount.

People who consume too much caffeine can experience an increased feeling of energy that lasts longer than average. This can be not very pleasant if your goal is to wind down at the end of the day. It can also be dangerous if you are operating heavy machinery, driving a car, or doing any other task that requires a higher level of alertness than usual.

If you have a habit of drinking energy drinks but aren’t feeling normal energy levels, you might be consuming too much caffeine.

Caffeine Withdrawal

When you consume caffeine regularly, your body adapts to this stimulant so that the effects are no longer as strong. This is why you might feel slightly different after your first cup of coffee in the morning, but not after the 5th one.

However, if you suddenly stop consuming caffeine, your body will suffer from withdrawal symptoms, including headaches, restlessness, irritability, and difficulty concentrating. When used in excess, caffeine can negatively affect your health.

Too much caffeine can lead to a condition called “caffeine dependence,” Your body has trouble producing neurotransmitters without caffeine. Excessive caffeine use can worsen migraines, increase blood pressure, and disturb sleep.

Brain Fog

Consuming excessive amounts of caffeine can have adverse health effects on your brain function. Caffeine is a diuretic and causes your body to flush sodium and water through your kidneys, resulting in headaches and other side effects of dehydration.

Too much caffeine can leave you feeling foggy-headed and cause you to have difficulty concentrating. Some people are more sensitive to the effects of caffeine than others, so it’s essential to be cautious and limit your consumption.

If you consume too much caffeine, you may experience brain fog symptoms, including headaches, difficulty concentrating, and lack of motivation.


Epileptic Seizure

The strongest stimulant in energy drinks is caffeine, which can worsen seizures in individuals with epilepsy. Certain medications used to treat epilepsy can increase the risk of attacks when combined with caffeine.

As caffeine can worsen seizures, limiting consumption when taking medication to treat epilepsy is essential. If you have epilepsy and consume energy drinks, it is essential to avoid large caffeinated drinks. Large caffeinated drinks include energy drinks, lattes, and specialty coffee drinks.


Food Cravings

Caffeine may increase hunger as it interferes with leptin in your body. When consuming too much caffeine, you may notice you crave items that contain fats and carbohydrates. These cravings may cause you to eat too much “comfort food” like burgers, fries, or pizza.

Craving for particular foods can be a negative side effect of caffeine for some who are trying to reduce cravings. This craving can make it challenging to consume nutrient-dense calories while losing weight.

Long-Term Side Effects Of Energy Drinks?

The long-term side effects of energy drink consumption are not well understood. More research is needed to understand the potential risks of regular energy drink consumption.

Some of the potential long-term side effects of energy drinks include:

  • Caffeine dependence
  • High blood pressure
  • Increased heart rate
  • Liver damage
  • Kidney damage

Long-term side effects of energy drinks are not well understood and can include changes in sleep patterns and anxiety, which can be caused by consuming too many caffeine drinks. These changes are typically reversible if excessive caffeine consumption is stopped.

Also, be sure to drink plenty of water when consuming energy drinks, as water is the best way to reduce the risks of dehydration. Dehydration can result in headaches, fatigue, and irritability.

The Substance Abuse and Mental Health Services Administration (SAMHSA) recommends that people with mental health conditions avoid energy drinks. The Centers for Disease Control and Prevention (CDC) also recommends that pregnant and breastfeeding women avoid energy drinks.


How To Avoid Energy Drink Side Effects

If you want to avoid the potential side effects of energy drinks, it is best to consume them in moderation. When consumed in moderation, energy drinks are generally safe for healthy individuals.
