Energy drinks were initially made for athletes, students and anyone who needs a boost or an extra jolt of energy, concentration and alertness. As it continually gains popularity, many concerns have been raised about the health implication of consuming energy drinks. Healthcare professionals warn of possible consequences for heavy energy drink consumers. Many researchers have also conducted research to discover more about this issue and present us with facts. Are energy drinks bad for you? Does energy drinks aid anxiety? Can Energy Drinks Cause Anxiety Attacks? And, what is the link between energy drinks and anxiety?

In this article, we will answer all the above questions and more. Let’s start by defining what really energy drinks are.

What are Energy Drinks?

Energy drinks are products promoted as being capable of mental stimulation and physical enhancement. They contain a high amount of stimulant, mostly caffeine and sugar, among other ingredients.

Stimulants are drugs that induce wakefulness, alertness, elevated mood, increased speech and motor activities. They basically stimulate the central nervous system and the brain.

But, prolonged use of these stimulants in high doses causes side effects such as restlessness, mood swings, irritability, anxiety, hyperactivity, and excessive speech. There are quite a number of stimulants out there, mostly for therapeutic purposes. Still, we will restrict our discussion to caffeine (methylxanthines), which is the main stimulant in most of the energy drinks available in supermarkets.

Methylxanthines are milder forms of stimulants which occur naturally in plants. Pure caffeine (trimethylxanthine) is odourless and has a bitter taste.

(Don’t worry though, we cover about other stimulants under the heading ‘What Does Consuming Energy Drinks Do To Your Body?’ below)

Types of Energy Drinks

Here are the energy drink types.

1. Energy drinks

The main stimulating agent in an energy drink is caffeine.

It is recommended that adults consume only up to 400mg of caffeine a day and 200mg per dose. An 8 ounce (237 ml) energy drink contains about 80 mg of caffeine, comparable to the amount in an average cup of coffee.

But then, energy drinks are sold in larger containers, with even more caffeine. Some of the additional ingredients are also natural sources of caffeine, like the guarana seed, which contains about 40mg of caffeine per gram. Hence, it is quite difficult to determine the actual amount of caffeine in an energy drink.

However, thankful to ‘social push’ in recent times, energy drink manufacturers are producing low sugar, low carb energy drinks suitable for people watching their sugar levels.

3. Energy mix

  • When driving long distances

Long-distance drivers deprived of sleep need to stay awake and alert while driving. They can consume energy drinks to help stay awake and alert.

Energy drinks help improve concentration, alertness as well as memory function. This is why energy drinks are popular among students.

  • When working

What Do Consuming Energy Drinks Do To Your Body?

You may want to ask what consuming energy drinks do to your body. Here are some of the ingredients in popular energy drinks and what they do to the body.

  • Caffeine

Caffeine is a stimulant that blocks the effect of adenosine (a brain chemical involved with sleep) and causes the neurons in the brain to fire. Then, the pituitary gland will think the body is under attack and initiate the fight or flight protocol by releasing adrenaline hormones.

  • Sugar

Most energy drinks are now low carb or contain no sugar at all, but sugar adds up to the calories in an energy drink.

  • Ephedrine

A commonly used ingredient found in decongestants and weight loss products, this stimulant works on the central nervous system.

  • B Vitamins

This group of vitamins improves muscle tone and can convert sugar to energy.

  • Taurine

Not quite sure its effects as a drink additive, but it is a natural amino acid the body produces. It helps regulate muscle contractions and heartbeat.

  • Ginseng

It is a medicinal root herb that reduces stress and boosts energy levels.

  • Inositol

Not exactly a vitamin, but a member of the vitamin B complex that helps cells in the body communicate.

When Should You Not Drink Energy Drinks?

We recommend you to strongly reconsider the habit in the following circumstances.

  • When the energy drinker has kidney disease or the drink is a ‘diuretic’.

This means it makes the kidneys release more fluid into the urine, causing less fluid in the body. Taking energy drink during or after exercising and sweating is dangerous and can lead to severe dehydration.

  • Drinking with alcohol

Alcohol also has dehydrating effects, so consuming energy drink mixed with alcohol can significantly drop your body fluids to a dangerously low level.

What are the Dangers of Energy Drink Consumption?

  • Migraines and headaches

  • Diabetes

High consumption of caffeine reduces insulin sensitivity, and that itself can lead to type 2 diabetes.

How to Differentiate a Good Energy Drink From a Bad Unhealthy One?

You can tell how healthy an energy drink is from the list of ingredients and nutritional content on the product.

But, remember, there are some unhealthy ingredients which may appear in different names in some cases. Some of them have been banned for athletes, so check the energy drink label to make sure you are not taking what is dangerous for you.

Tips for Reading an Energy Drink Label

  • Energy dosage

The first thing to watch out for is the amount of caffeine per serving in the energy drink. The energy drink with the lowest caffeine per serving is a much healthier option.

  • Sugar

Watch out for the carb content if you are on a diet, or want to maintain a healthy lifestyle. Type 2 diabetics should opt for low carb or zero sugar energy drinks to avoid blood sugar spikes.

  • Additives

Sodium, high fructose corn syrup, artificial coloring, artificial sweeteners, are all ingredients to watch out for. They are dangerous in high doses and some are carcinogenic.

How Energy Drinks Affects Anxiety and Depression?

Energy drinks are loaded with stimulants, sweeteners and a handful of other ingredients, and they are easily accessible to anyone even minors. It is no surprise that there are increasingly dangerous side effects amongst the younger population who often consume more energy drinks than necessary.

Some people are prone to feel increasing anxiety after consuming caffeinated drinks like energy drinks because their adenosine receptors have 2 different generic variations. The fight or flight response is triggered as a result of consuming energy drinks.

As such, if you are addicted to energy drinks, the chances are you carry a risk of anxiety and depression later in your life.

What Does Research Say About The Link?

A recent study published by the Frontiers in Public Health Journal shows that people could be taking more caffeine than is safe due to the high levels of caffeine in energy drinks. Apart from upsetting your sleep pattern, it can upset your mood, and these two are symptoms of depression and stress.

Other research studies have implied while energy drinks may increase the risk of mental health outcomes that are undesirable, it was impossible to prove for sure the direct cause and effect.

Research also suggested that emotions can be impacted by the number of energy drinks consumed. For instance, 250 mg of caffeine made a subject feel elated, and 500 mg increased the subject’s irritability, so it could be said that caffeine affects a person’s mood.

Can Energy Drinks Cause Anxiety Attacks?

Yes.

Caffeine is a stimulant that affects the CNS (central nervous system) and increases blood flow and heart rate, and therefore, is not a good idea for someone with anxiety.

Too much caffeine can cause jittery effects and leave you moody. Now the combination of high dosage of caffeine and a handful of other stimulants found in energy drinks can make an anxious person even more anxious, and can even lead to anxiety attacks.

Do Energy Drinks Make Anxiety Worse?

Yes. If too much caffeine can lead to anxiety attacks, then you can be sure it can make anxiety worse. Because caffeine can be addictive, it may be difficult to avoid or stop, and that will lead to prolonged consumption in high doses. That’s just bad news for someone already suffering from anxiety.

What Can I Drink Instead of Energy Drinks?

Several other options boost your energy and help to keep you alert apart from energy drinks. They are a much more healthy option even if they may not give you the same amount of energy boost as an energy drink does.

  • Yerba mate

Yerba mate is prepared the same way you would prepare green tea or black tea.

It contains a bit of caffeine and some other incredibly beneficial substances. Part of it is beneficial factors are antioxidants and minerals which are healthy choices.

It is not addictive or acidic like coffee but lightens your mood while keeping you healthy.

  • Green tea

Whether taken hot or cold, teas boost your energy because they contain a bit of caffeine, and then some extra health beneficial substances. Green tea contains minerals and antioxidants beneficial to your health and wellness.

It also provides the necessary energy to keep you alert and healthy.

  • Protein shakes

Fatigue is commonly caused by lack of protein. A simple protein shake with some carbohydrates for faster energy conversion is enough to boost your energy level.

You can prepare a protein shake by mixing 10 grams of protein form of milk, soymilk, yoghurt or powder into your shake, and then you can add quinoa, wheat germ or fruits.

Tip: Here are the best protein drinks for diabetics.

  • Fresh juice

While we may be tempted to fuel our body with sugar-loaded snacks, our bodies can also produce energy when we consume healthy food. Caffeine is also not the only source of energy, Green and fresh juices help you feel awake and full.

You can make juices from quality ingredients such as nuts and seeds (rich in protein), leafy greens (for vitamins and iron), berries (antioxidants), kiwi, banana, citrus fruits and so on.

  • Ginger root tea

This tea does not contain caffeine or provide an immediate energy boost, but it has its benefits. Prolonged consumption of ginger root keeps you healthy and maintains your energy levels.

It prevents Alzheimer’s disease, aids digestion and the immune system.

  • Water

The water they say is the world’s best ‘energy drink’.

Dehydration causes slow metabolism and makes you feel sluggish. Drinking enough water will help keep you hydrated as well as aid fast metabolism so that your body can produce enough energy.

You can add strawberries, blueberries or fruit slices to spruce up your cup of water and add extra nutrition.

Conclusion

Energy drinks are known to improve mental alertness, memory, concentration, and fast reaction time while reducing mental fatigue. Many studies and research have also agreed with this, and have attributed this to caffeine and sugar. But while it helps many to stay alert and awake to get through their day, the side effects of prolonged consumption of high doses of caffeine, sugar and some other components such as artificial coloring and sweeteners pose a major threat.

To avoid side effects such as anxiety, insomnia, depression, heart problems and so on, it is advised that no more than 400 mg of caffeine should be consumed in a day.

Opting for other energy drink alternatives will also help in regulating the amount of caffeine consumed. Everything should be taken in moderation to maintain a healthy lifestyle.
