Coffee Can Improve Energy Levels and Make You Smarter

Coffee can help people feel less fatigue and increase energy levels.

That’s because it contains caffeine, which is commonly consumed psychoactive substance in the world.

After you drink coffee, the caffeine is absorbed into your bloodstream. From there, it travels to your brain.

In the brain, caffeine blocks the inhibitory neurotransmitter adenosine.

Besides, when this happens, the amount of other neurotransmitters like norepinephrine and dopamine increases, leading to enhanced firing of neurons.

Lastly, many controlled studies in humans show that coffee improves various aspects of brain function, which are including mood, memory, energy levels, reaction times and mental function.
