As in most cases, whether coffee has a positive or negative effect on health depends on the dose. In excessively high doses, caffeine can lead to anxiety, restlessness, nervousness, irritability or even insomnia. Scientific studies give a threshold of around 1.2 g caffeine per day.

In the long term, consuming 2 to 5 cups a day can have a positive effect on mortality. Caffeine probably has a negative effect in combination with alcohol.

Cardiovascular system

Caffeine speeds up the heart, metabolism and breathing. Blood pressure and body temperature rise slightly. The blood vessels expand and the blood flow to all organs increases.

Concentration, alertness, attention

Caffeinated drinks have a stimulating effect, activate the central nervous system and increase mental and physical performance.


Caffeine has a stimulating effect and has a short-term positive effect on wakefulness and performance. Contrary to some speculation, however, this does not compensate for a sleep deficit.

Quite the opposite; for some people, caffeine consumption has a negative effect on sleep behavior after a certain time. It can lead to problems falling asleep. The reason for this is presumably genetic variants of the so-called adenosine receptor. This explains the effect of caffeine. It binds to the receptor, blocks it and thus increases alertness and reduces tiredness.

Water and electrolyte balance

Caffeine has a diuretic effect. However, even at doses of up to 400 mg daily, this does not have a negative effect on the water and electrolyte balance over a longer period of time.

Java burn: What is the effect of caffeine?

Caffeine can cross the blood-brain barrier. This normally protects the brain from penetrating harmful substances, almost unhindered. Thus, it quickly reaches the brain and acts mainly in the central nervous system. It owes its stimulant effect primarily to one property.

Caffeine is very similar to the chemical structure of the messenger substance adenosine. The job of adenosine is to signal tiredness to the body. It is formed when your nerve cells are overly active. Then it is deposited on the nerve cells eager to work, restricts their exchange and triggers a feeling of tiredness in order to protect the brain from overload. Caffeine blocks the adenosine receptors of these nerve cells and the feeling of tiredness is weakened.
