A Brief Discussion on Why Is Coffee Bad for You

Coffee is a remarkably healthy drink. It has a lot of benefits like boosting mental & physical performance, increasing focus, burning fat, even minimizing the risk of cancer. However, excessive consumption of caffeine results in a lot of negative impacts on your mind and body.

To be more correct, the effect of caffeine varies from man to man. People who are not habituated to caffeine may show negative symptoms after drinking what is generally considered an average dose.

Let’s dip into the negative aspects of coffee, more specifically, caffeine.


Many regular coffee drinkers can easily get trapped into consuming too much caffeine. However, studies revealed that coffee does not cause addiction similar to other drugs like cocaine or amphetamines, yet it can create psychological and physical dependency, mostly at heavy dosages.

Besides, the frequency of caffeine consumption may also cause addiction. So basically, coffee is good, but if you start to take ‘too much of a good thing,’ it may turn out to be harmful.

Insomnia & restlessness

Coffee is famous for its contribution to helping us stay awake. From this, you might gaze at the next point, which is: that drinking too much can hamper regular sleeping, and you may not get enough reviving sleep.

Researchers said that higher dosages of caffeine delay the time required to fall asleep, reducing the total sleeping period.

The truth is, how much caffeine you can take without causing insomnia varies from man to man, depending on your genetics and other elements. An essential piece of information: caffeine that is consumed in the late hours can cause sleep problems because its effects take a few hours to disappear.

The lesson to be learned, caffeine may help stay awake & recharge, yet large dosages cause insomnia. Also, get rid of the afternoon coffee breaks if you are going through sleep problems.

Anxiety and nervousness

To realize how caffeine causes anxiety, we have to understand its mechanism first. Caffeine prevents adenosine’s impact which provides a sense of tiredness; simultaneously, it activates the adrenaline related to increased energy.

Therefore, when we take high doses of caffeine, these effects become more strong. As a result, issues like anxiety, nervousness, or jitteriness develop. The American Psychiatric Association enlisted anxiety disorder due to caffeine among the four caffeine-related syndromes.

However, the effect of the same amount of caffeine varies from man to man, and also the caffeine content varies from brand to brand. What you need to do is, if you feel nervous or jittery frequently, then monitor your coffee intake.

Digestive problems

Coffee usually helps in bowel movement. The laxative effect of coffee causes the release of gastrin, a hormone that increases colonic activity.

In addition to this, coffee increases the contractions responsible for moving food within the digestive tract. Thus, higher doses of coffee may result in loss of stools, even diarrhea for some people.

Besides, studies found that coffee deteriorates the condition of some GERD (Gastroesophageal Reflux Disease) patients. That’s why, if you are having digestive issues, try reducing your coffee consumption.

High blood pressure and faster heart rate

Although high doses of caffeine seem to enhance the rate of blood pressure, however, generally speaking, it doesn’t raise the risk of stroke or heart disease for most people (it is debatable though). Also, increased BP is a temporary fact.

But if you have high blood pressure beforehand, then it is better to be careful about high doses of caffeine. In some cases, the heart rate seems to increase due to caffeine’s stimulatory effect (large doses obviously). However, this doesn’t happen to all and varies from man to man.


It might sound odd, but yeah, coffee, tea, or other caffeinated beverages can gradually generate fatigue or exhaustion. How can that happen when we know they doing the exact opposite?

Well, it is the rebound effect that comes after the effect of caffeine wears off. Frequently taking a lot of caffeine all over the day can stop the rebound effect, but this is not an option and something we should not get used to, right? The solution is, to be moderate in your coffee intake.

Muscle breakdown

Although it is comparatively rare, people may experience the breakdown of damaged muscles, namely Rhabdomyolysis, due to excessive caffeine intake. Rhabdomyolysis is an extreme situation that causes damaged muscle fibres to enter the bloodstream. It can even result in kidney failure and other issues.

Increased urination and urgency

All of us usually experience this often, especially on the days when we drink coffee or other beverages too much.  Researches show that high caffeine intake can generate increased urination and urgency by its stimulatory effect. The solution is minimizing your caffeine consumption.

In addition to caffeine’s described negative aspects, researchers also said that caffeine might cause breast tissue cysts in women, reduce fertility rate, increase miscarriage risk, and worsen menopause symptoms.

However, these types of issues are debatable and should be discussed with professionals. The same goes for other controversial issues related to caffeine.

As an Endnote

We can sum it up like this – light to medium amount of caffeine intake is beneficial for health while drinking high dosages has many side effects. Although caffeine’s effect varies from one person to another drinking a lot of coffee is not a good idea.

If you regularly drink coffee or any other caffeinated beverage, monitor your sleep, energy levels, blood pressure, urination, etc. If something is wrong, then maybe it is time to reduce your coffee drinking rate. I hope this piece was beneficial to show why is coffee bad for you.
