How does caffeine work in your brain?

So what caffeine does is that as soon as you drink a cup of coffee and the caffeine finds its way to your bloodstream, it reaches the brain and binds to the adenosine receptors. Now when caffeine has bound with the adenosine receptors, the adenosine won’t find the receptors to attach to, thus it won’t be able to carry out its function.

Now the question arises “What is the function of adenosine?” and “How blocking adenosine activity is related to alertness and attention?” Adenosine is the neurotransmitter that regulates the sleep cycle and also has an impact on the level of alertness and attention. So what adenosine does is that as soon as it gets attached to its receptor, it sends the signal to the brain that now it’s time to sleep.

Now in the scenario, where caffeine has blocked all the adenosine receptors, adenosine won’t be able to carry out its function, thus you will be focused and will stay awake.

Does coffee help you stay awake?

Yes, coffee does help you stay awake. The caffeine present in the coffee binds with the adenosine receptors and stops the adenosine from carrying out its function. The adenosine induces sleepiness by sending signals to your brain. So when adenosine won’t be able to bind with its receptor, it won’t be able to carry out its function, thereby you will stay awake.

Different varieties of coffee differ in their caffeine content. For instance, an 8-ounce cup of coffee contains about 95-165 mg of caffeine depending upon how strong it was. As the decaffeinated coffee has most of its caffeine part eliminated, therefore, it has only 2-5 mg of caffeine in the 8-ounce cup while 1-ounce espresso has somewhat 47-64 mg of caffeine present in it.

One thing that you should always remember is that the more roasted the coffee beans are, the more will be their caffeine content.

How long does it take for the caffeine to kick in?
