Caffeine in coffee

What is caffeine and what happens if you consume too much caffeine? When are you addicted to caffeine and how do you get rid of it?

Caffeine in general

Caffeine is a stimulant. This is found in coffee, tea, cola, smart drinks or energy drinks. Regular caffeine is a white powder with a bitter taste. It is sold in pill form but also in drinks. It comes from a plant and is only addictive if you drink too much of it.


It is a stimulating drink that wakes you up. In the short term, your concentration improves and your fatigue is suppressed. Too much caffeine can cause insomnia, restlessness and damage to the heart and blood vessels. All this is because the central nervous system, breathing and heart muscle are stimulated. It starts to work after about fifteen minutes and can take about an hour to wear off again. It is classified as a drug and therefore has an addictive effect. You can become accustomed to caffeine, causing you to need more and more to feel good. Not every product contains the same amount of caffeine and that is a good thing.

Addicted to caffeine

If you take very little caffeine you will probably never become addicted to it. If you drink two cups of coffee a day you can become addicted. You only notice this if you suddenly stop taking caffeine. Then you have withdrawal symptoms. It is better not to stop all at once, because it is much better to taper off slowly so that your body can get used to this.

The risks

If you have heart problems, it is better not to drink or use too much caffeine because this can cause heart rhythm disorders. Too much caffeine can make you nervous or anxious. Restlessness and sleep disorders are also a risk. The heart rate increases and you may experience palpitations.
