Why Do Energy Drinks Make Me Tired? (Find Out)

Why Do Energy Drinks Make Me Tired? (Find Out)

In spite of the fact that caffeine is a stimulant that enhances alertness, it might actually cause you to feel sleepy. This is because if you consume too much caffeine, your body will develop a tolerance to the substance, so it won’t keep you awake the same way as it did previously.

That’s weird, isn’t it? Shouldn’t an energy drink give me energy instead of making me feel tired? Well, the answer to that is not so simple, given the fact that chemistry and biochemistry are complicated matters.

Through this article, I will try to shed some light on this subject. So keep reading until the end to find out why energy drinks make you feel tired sometimes.

Why Does Caffeine Make Me Sleepy Immediately?

Caffeine causes havoc within your body’s natural processes. Consequently, your brain produces even more adenosine in an effort to counteract the overstimulation. This is why, the moment you down that can of energy drink, you may immediately feel sleepy.

Notwithstanding the fact that your body has likely developed a tolerance to the stimulant effects of coffee that prevents you from feeling awake and energetic throughout the day.

To put it simply, a frequent intake of caffeine may cause your body to develop more adenosine receptors because caffeine prevents the effects of adenosine. So, as a rule of thumb, the more receptors you have, the less effective the energy drink is as a stimulant in the long run.

With that in mind, the FDA recommends that you consume no more than 400 milligrams of caffeine daily since excessive intake has been linked to many adverse health impacts and conditions. As a result, overindulgence may be harmful and even fatal in extreme cases.

Examples of these are:

  • Sugar crashes
  • Dehydration
  • Vomiting
  • Elevated blood pressure
  • Dizziness

Can Energy Drinks have the Opposite Effect?

They certainly do! Drinking energy beverages does not guarantee you the same benefits everyone is raving about!

Now, caffeine may be the obvious culprit in these energy-buzzing beverages, but a sugar crash should also be blamed.

It’s no secret that the majority of the population like their drinks sweet. Therefore some energy drinks manufacturers fill their products with sugar. That is why overconsumption of energy drinks raises insulin levels in the body.

With that, your blood sugar levels fall as a result of the insulin, which in return, will let you feel all sorts of side effects such as drowsiness. 

As a result, it becomes a product that’s the complete antithesis of what energy drinks are all about.

What Ingredients in Energy Drinks Help with Tiredness?

Thanks to caffeine, you may get a short burst of energy from energy drinks. However, your caffeine tolerance should be considered while looking for an energy drink that can help keep you alert.

Furthermore, an energy drink’s energizing effects may be partly attributed to Guarana’s presence. Basically, Guarana is naturally high in caffeine, and it enhances the caffeine results in these beverages, making you feel more awake and energetic.

Not to mention, it is also well-known that Guarana has several advantages, including enhanced physical and mental efficiency.

How Do I Boost my Energy when I’m Tired? 

There’s no need to chug cans of energy drinks to get through the day. Here are a few things to consume or do to get those bones and muscles of yours revved up.

Drink Water

While working out or going about your day, it may be challenging to remember to drink enough water. Drinking water provides you more incredible energy to perform anything, from athletic feats to staying up doing study sessions.

Grab a Bite

Your body’s energy levels may be boosted or drained by the food you eat. In fact, when you don’t get enough fuel for your body, your energy and mood will decline.

In particular, every bite we take turns into glucose, which powers our brains and keeps us sharp. For whatever reason, our attention tends to wander when we’re running short on glucose. This explains why it’s so difficult to do anything when you haven’t had anything yet for breakfast. 


Exercising may be the last thing on your mind when you’re tired. However, I’m here to tell you that exercising can be the most beneficial thing you can do for your body and activity levels.

Generally speaking, most people’s daytime energy levels increase directly in proportion to their productivity. You may get it while you work out since your brain releases endorphins when you work out.

Think of it as setting the moment, to keep your ball rolling.

Final Say

There are two primary ingredients in energy drinks: sugar and caffeine, and although the latter might give you a rapid burst of energy, they can also drain your energy levels over time.

Despite the fact that energy drinks may aid enhance performance, the impact is just temporary. Sugar and caffeine, when combined, have the potential to cause you to overwork yourself.

To gain the same performance-enhancing advantages, undertake some exercise and consume a balanced diet.
