Caffeine travels to the human brain and connects with Adenosine receptors. This way coffee tricks your brain into thinking you are not tired. Thus you can keep on working for long hours and kill the drowsiness after a long meeting. At the same time, it triggers the release of adrenaline in your body, which gives your body an energy boost. 

But if you take excessive amounts of coffee each day, these chemical substances might have a more substantial effect on the body. Once you reach that state, you will feel more anxious.

According to the American Psychiatric Association, Caffeine-Induced-anxiety is caused by excessive consumption of coffee. 

Insomnia

Muscle Atrophy

Rhabdomyolysis is a dangerous health condition that breaks down the human muscle. The dead muscles then enter the bloodstream and result in kidney failures and other serious issues. Rhabdomyolysis is a direct result of snake bites, drug abuse, trauma, and muscle strain. But excessive caffeine in the body can also trigger this health condition. 

If you are used to drinking 2-3 cups of coffee each day and never had any harmful side effects, you don’t need to worry that much. But if you are new and aren’t accustomed to drinking coffee, you should limit your daily caffeine intake to 250 milligrams a day. 

Withdrawal

There is no doubt that caffeine gives an energy boost to the body, and it stimulates the brain. But the effect of caffeine starts to fade away after roughly 6 hours. When that happens, the body experiences a rebound of fatigue. 

This rebound effect can make people feel more tired and exhausted. However, you might not feel its impact if you make yourself another coffee right before the rebound kicks in.

High blood Pressure

Caffeine stimulates the human nervous system, thus manipulating the average blood pressure in the human body. As high blood pressure runs the risk of permanently damaging the arteries’ muscle, it can lead to heart attack and stroke.

If you already have high blood pressure, you should avoid drinking coffee.  

Dependency

You might not think that caffeine can grow into an addiction for you. And compared to other hard-core drugs, you are right. Caffeine won’t get you hooked.

However, with time, people might start to grow a dependency on coffee. Once they reach that stage, they will find it hard to focus on the task at hand without drinking a cup of coffee first. Also, caffeine triggers some brain chemicals that are usually triggered by amphetamines and cocaine. 

Increased Heart Rate

Soon after you drink a cup of coffee, you will realize your heart has started to beat faster. The worst thing that can happen to you is atrial fibrillation. Under this condition, your heart starts to beat in alternate rhythms.

However, this is very rare. Unless you consume excessively high caffeine or highly-concentrated caffeine energy drinks, you are not much likely to experience atrial fibrillation.

Conclusion 

Now that we know the side effects of coffee, it is important to understand that different people respond differently to caffeine. And it all boils down to their gene. 

However, if you stick to a moderate coffee dosage per day, you won’t develop any severe side effects of caffeine on the body. As mentioned earlier, 400 milligrams of coffee a day is the benchmark for healthy individuals.
