Because of this, the user will experience fatigue, sleepiness, and lack of concentration. Therefore, it is recommended to use healthy foods, get enough sleep, and exercise regularly instead of consuming energy drinks to increase your body’s energy level.

On the other hand, the caffeine present in this drink will cause a lack of concentration and restlessness in people. Therefore, avoiding excessive consumption of this type of drink is better.

Why Do Energy Drinks Make Me Tired

Energy drinks are produced and consumed to increase alertness and reduce drowsiness. Especially when we have a lot of things to do but lack the energy to do the work, we usually turn to energy drinks. In many cases, using this type of drink quickly increases the energy level. But using energy drinks in the long run will have the opposite effect. This means that due to the high level of caffeine and sugar, drinking this drink causes fatigue and sleepiness instead of increasing the energy level. Of course, only sugar and caffeine will not cause this fatigue. Other ingredients in this drink will also cause drowsiness in the long run. These compounds include:


Adenosine in the body is responsible for creating a feeling of sleep. Caffeine suppresses the action of adenosine in the body. For this reason, reducing the effects of adenosine increases the level of other neurotransmitters such as dopamine and norepinephrine. This action increases the level of alertness and concentration. However, excessive use of this substance can cause disorders in the body.


Energy drinks have high levels of sugar. This substance is quickly digested in the body, and glucose is produced. Glucose increases the blood sugar level and thus the body’s energy. However, its excessive consumption causes an increase in insulin production in the body and, as a result, lowers blood sugar. Of course, some energy drinks have artificial sweeteners that do not increase calories.

B group vitamins

B vitamins play a very important role in increasing the body’s energy level. Most energy drinks contain high B vitamins, especially B6 and B12. These vitamins play a role in the metabolism of various substances and energy production from carbohydrates, fats, and proteins.


Taurine is an amino acid widely used in the composition of energy drinks. This amino acid helps to regulate calcium levels in cells. For this reason, it can improve muscle function and relieve fatigue.


Guarana is a plant extract that contains caffeine. This plant extract increases the percentage of caffeine in energy drinks.
