Here’s What Happens To Your Heart If You Drink Energy Drinks


Caffeine is considered to be very beneficial for the body and the mind. It is considered to sooth headaches, enhance mental ability, and treat health issues, like diabetes and asthma.

Nevertheless, if caffeine is used in combination with artificial stimulants, sweeteners, or cocktails, it may be toxic for your body, so that it may lead cardiovascular issues or even heart attack.

A case in point is Cory Terry, a 33-year old father, who died of a heart attack after consuming energy drink. Even though he was non-smoker and was active, he drank energy drink daily.


According to a study at the Mayo Clinic proceedings, drinking energy drinks may have side effects in people, who suffer from cardiovascular problems. 150 participants, who took part in a study, were given to drink energy drinks (500 ml = two cans) daily for a week.

The findings of the study have shown that the blood pressure of the participants increased by 8 % 4 hours after consuming the drink, rising to 10 % after a week. The findings have also shown that the heart rate of the participants was increased by 8 % on the 1st day, rising to 11 % on the last day.

The high blood pressure and the heart rate are closely linked to experiencing heart attack. Namely, high blood pressure may cause artery damage and blood clots, which in turn leads to heart strokes. In addition, increased heart rate heightens the risk of experiencing heart attacks.

Ella Allred, a Technical Nutritionist, talks about the affects energy drinks have on the human system. She claims that energy drinks are a harmful way to get caffeine. Most people drink energy drinks on a daily basis to survive a busy week.

First 10 minutes

After drinking energy drink, the caffeine is absorbed into the bloodstream, and the body responds with increasing the heart rate and the blood pressure. Ella added that caffeine is very addictive – the more we drink the more we need – and we end up caught up in a vicious circle. The main effect of an energy drink on the human body is increased blood pressure, which is harmful for the heart and the kidney health.

15 – 45 minutes

In the first 15 – 45 minutes, depending on how long you drink it, the caffeine levels will increase, you will feel awaken and your concentration improved. It occurs as a result of the caffeine, which acts as a drug stimulant.

30 – 50 minutes

When you finish the energy drink and caffeine was absorbed by the body, the liver will react with absorbing even more sugar. Energy drinks are loaded with sugar in order to increase the blood glucose levels and to give us quick energy. Eva stated that the high levels of glucose may cause the pancreas to release insulin, which in turn can increase the risk of developing diabetes type 2.

60 minutes

In 60 minutes you will be experiencing the ‘sugar crash’. It is a combination of the sugar levels in the bloodstream decreasing and the effects of caffeine going down. Ella said that if the caffeine has worn us off, we may experience energy crash and bad moods. The constant increases and decreases of energy as well as sugar levels can affect people’s work, exercise, or the activityr they are using the energy drink for.

After 5 – 6 hours

About 5 – 6 hours after consuming the energy drink, the body will reduce the amount of caffeine in the bloodstream by 50%. In women, who use oral contraceptives, this time may be doubled.

After 12 hours

After 12 hours of consuming the energy drink, the caffeine will be eliminated of the bloodstream, but even though it varies from one person to another.

12 – 24 hours

Between 12 – 24 hours, you are likely to experience negative symptoms, including the need for caffeine, headaches, and constipation.

The liver needs about 12 hours to deal up with the caffeine. At the same time, it does not focus on eliminating other toxins from our body, which can cause other illnesses.

7 – 12 days

Studies have indicated that the body needs nearly 7 – 12 days to get tolerant of the daily caffeine intake.

Ella said that in order to save ourselves from sleepiness and tiredness, we will also crave for another energy drink, thus starting the process of ignoring need for rest and nutrition of the body.


Except lots of carbohydrates and sugar, energy drinks is loaded with stimulants, like amino acid taurine, caffeine, as well as a few B-group Vitamins. Even though it has not been still proved that these ingredients of energy drinks have side effects in people, studies have shown how the combination of these ingredients affect people’s health.


A study investigated the effects of energy drinks in people during or after doing exercises. 13 participants took place in the study. They performed exercises 3 times a day, and before doing exhausting exercises, they were given energy drink.

The findings of the study have shown that the consumption of energy drinks affected the stroke volume, i.e. the amount of blood pumped out of and in the heart.

The findings have also indicated that the compound of energy drinks may have not side effects in people if they are used independently, but if they are used in combination, they may affect the cardiovascular system, and lead to increased risk of experiencing heart attacks.

To sum up, the findings of the study have shown that we were right. It means that energy drinks are not beneficial for the heart health. If you need to refresh yourself, take coffee or other drink, which contains only one stimulant, instead of the energy drinks.
