Caffeine is a good stimulant, and it can keep you awake and active for several hours. You might even use it as part of your productive routine.

Many energy drinks have considerable amounts of caffeine to help you stay alert and feel energized for a while.

Nevertheless, the good of caffeine has limits. Learn the effect of drinking too much caffeine to save yourself from potential life problems in future and to adjust your consumption according to lower the negative consequences.

Expect an Increase in Your Heartbeat

Too much caffeine will stimulate blood pumping in the body leading to the increase in your heart rate. This effect would only be good for a short while. You might also get away with it when it happens occasionally. However, continued abuse of the stimulant may cause long-term problems with the heart and with your blood pressure.


The stimulant overrides your brain function and causes you to behave abnormally. For instance, you might stay active even though your eyes are tired after hours of studying. The underlying fact is that you will be forcing the body to act in a way that it does not know and that will create imbalances in your brain hormonal regulation. A consequence of the disturbance of hormones is that feeling of restlessness even when you are seeking to relax or sleep.

Heartburn and Reflux

Many people are on anti-acids because they want to get rid of the reflux problems they experience. However many of them have no idea that the cause of their problem might be due to the relaxation of the esophagus because of the caffeine. The effect is causing the throat areas to be susceptible to reflux, and it can lead to increased conditions of heartburn.


Just as caffeine leads to restlessness, it can also contribute to anxiety. Not having sufficient rest and messing with the hormonal balance in the body are two main conditions that aggravate anxiety. Unfortunately, caffeine helps to the two conditions, and it, therefore, has a direct link to heightened levels of feeling anxious, which would possibly lead to future health and mental problems. The caffeine also stimulates senses causing people to have overwhelming sensations.

Visits to the Washroom

Caffeine causes diuresis. You will experience the urge to go and release yourself almost immediately after you consume caffeine. The problem will worsen as you keep taking more caffeine and you may discover that it is affecting your concentration and your capabilities to meet work deadlines. Other people working close to you might also consider you as a nuisance especially when you have to disturb them on your out of the work area.

The continued reliance on coffee, energy drinks, and tea, as well as many caffeine stimulants, will cause you to lose sleep. The ingredient inhibits your adenosine, a neurotransmitter that acts as a natural tranquilizer. You end up being unable to sleep even when you want to, and that could have disastrous effects on the rest of your health.
