1. Makes you smarter and improve energy levels

Coffee increases energy levels of humans which makes people feel less tired. Caffeine, an ingredient which exists in coffee acts as a stimulant. After consumption, this ingredient gets absorbed in the blood and thereby travels to the brain. This can block the inhibitory neurotransmitter adenosine. This causes other neurotransmitters such as norepinephrine and dopamine to increase. This causes the enhanced firing of neurons.

However, scientific controlled studies prove that coffee can develop many sections of the brain effectively such as mood, memory, energy levels, vigilance in humans.
