Coffee is a very powerful drink that is part of Brazilians' daily lives. Most people need a cup of the black liquid to wake up and start their daily tasks. But you may have heard of those people who drink coffee and feel nothing.
That's right, they no longer stay awake and much less have that “differentiated” tremor if they drink some coffee after 6pm. This (lack of) reaction is normal and there is a scientific explanation for this. Continue reading and find out.

According to a report published by the website Terra, there are different factors that influence how caffeine works in a person's body – and some involve genetics. So, if coffee doesn't wake you up, you can ask your parents for an explanation.
Jokes aside, it works more or less like this: the CYP1A2 gene defines how our body reacts to caffeine. It controls an enzyme that breaks down this substance from coffee to make it act in our organism.
The type and quantity of this enzyme influence whether it will be eliminated faster or slower from the body. Some people have two copies of the enzyme and this causes coffee (and caffeine) to be metabolized faster.
In addition caffeine, at some point, it can also bind to the same receptors as adenosine. It is responsible for the feeling of tiredness. Therefore, it blocks the action of coffee. And they stay for them.
And don't think that drinking more coffee will make this action of our body ineffective. Quite the opposite. The body can produce even more adenosine receptors. And this, over time, can increase caffeine tolerance.
But there are also those who are born with more adenosine receptors than normal.
Like many substances stimulants, it is possible (read well, possible) that, over time, you create more “resistance” to coffee. That is, if you drink too much, it may stop working.
So, drink your coffee, but be careful!
