What coffee does to your brain? How does coffee works? Coffee wakes us up in the morning and keeps us alert in the entire day. Caffeine is the most misunderstood matter. It is both an upper, and it differently works on various drinkers. The first thing that we need to know about coffee is that part of our usual fatigues is from adenosine, a molecule that is created by our body whit it gulps along the whole day. As we sleep at night, the adenosine concentration drops, slowly boosting wakefulness. At the same time, more adenosine produced, the sleepier we feel.

Our morning cup hijacks that adenosine concentration because caffeine act up the brain cells. Due to the same shape, caffeine can fasten adenosine receptors to the brain. Once the caffeine is attached into the rightful spot of adenosine, there is no other way for it to go around, which avoids it to build-up and makes us sleepy. Without adenosine that normally leads to tiredness, the usual stimulants run active. This makes us awake for a while. However, this has come to an end, as our brain rapidly wises up to our caffeine tricks.

What coffee does to your brain? When adenosine continuously blocked from sticking to its receptors, eventually, our body produces more receptors, which likely we need even more plug up of caffeine. This habit can be difficult to let go, and makes us need more caffeine to keep us active all day.

Letting go of coffee is like quitting smoking. When we miss our daily intake of coffee, we may feel more tired than usual and may experience some withdrawal symptoms. This is more difficult than you would have not taken coffee before. Caffeine does not only block adenosine, it also boosts adrenaline levels and our mood, the same thing as cocaine does, just a lesser evil.
