Coffee drinkers are seriously sad: why does drinking coffee lose its sobering quality over time, according to science?

The most preferred time for coffee is when we feel sleepy. But addicts know very well: After a while, coffee can no longer induce sleep.

So what exactly happens to cause coffee to lose its sobering properties? According to science, there are some answers.

First, how does coffee sober up?

coffee

The caffeine in coffee binds to adenosine (a natural inhibitor of the brain and causes a feeling of fatigue when it binds to these receptors), receptors in brain cells and It suppresses the feeling of tiredness/sleep. This is how we become more powerful.

We acquire immunity through regular caffeine intake.

When we regularly consume caffeine, our body adapts and increases the production of adenosine receptors. If we consume the same amount of caffeine, we see less impact And we can’t feel powerful by drinking coffee.

In addition, the enzymes that break down caffeine in our liver are produced more, and caffeine, It is quickly removed from the body. The effect is therefore not long lasting.

Neurotransmitter levels also change.

Caffeine, which increases the release of neurotransmitters (chemicals that allow communication between neurons or between a neuron and another type of cell) such as dopamine and norepinephrine, reduces the feeling of fatigue, but over time decrease in the level of neurotransmitters It happens. On the other hand, our body responds less to the increase in neurotransmitters.

Finally, there is of course also the psychological effect. some people “I can’t wake up in the morning without drinking 2 shots of espresso…” proverb he conditions himself and he thinks that if he doesn’t take this amount, he won’t feel powerful.
