16 Health Risks of Consuming Too Much Caffeine


Over 80% of people in the United States consume around 200 mg of caffeine each day, which is no surprise when we look at how easy it is to come by. Caffeine is present in coffee, tea, energy drinks, cola and even chocolate to name just a few.

Caffeine changes the way the body works, and while it may prove to be an effective stimulant, the effects can be unpleasant or even dangerous when too much has been consumed.

There are a number of signs and side effects that may indicate you’re consuming more caffeine than is recommended.

The Effects:

High Heartbeat Rate

Due to the stimulating properties of caffeine on your central nervous system, it is normal for your heart rate to increase within 15 minutes of consuming it. If you’re experiencing a higher heartrate more often than not, this could be a sign you’re consuming more caffeine than your system is willing to handle.


When you consume caffeine, your esophagus becomes relaxed, which contributes to gastroesophageal reflux. This can cause heartburn to those who are susceptible, which can be an uncomfortable experience.

Feeling Jittery

While it’s normal to feel a little restless after a cup of coffee or energy drink, feeling constantly jittery is a clear sign you need to cut back. Caffeine stimulates the hormones within your body, such as adrenaline, which causes jitters and tremors.


The aforementioned afflictions, such as an increase in heart rate, heightened adrenaline and stimulated senses can be overwhelming to the body, resulting in feelings of anxiety. If you’re feeling ‘on edge’ and can’t think why, it’s very possible you’ve had one too many cups of coffee.

Muscle Spasms

A prolonged use of caffeine in abundance can lead to regular muscle twitches or spasms, as the stimulative effects can cause involuntary, erratic movements. This can be alarming when unexpected and is a clear cut sign an individual needs to cut back before doing further damage to their system.

Disorderly Thoughts and Speech

Caffeine speeds up your senses and abilities, which in this case include thought and speech. This is often considered useful in the correct circumstances, for example when battling through a last minute project, however it can result in confusion or stuttering when taken too far.
