Coffee can help people feel less tired and increase energy levels
In the brain, caffeine blocks an inhibitory neurotransmitter called Adenosine. When that happens, the amount of other neurotransmitters like norepinephrine and dopamine actually increases, leading to enhanced firing of neurons.
Coffee improves various aspects of brain function. This includes memory, mood, vigilance, energy levels, reaction times and general cognitive function.

When you drink coffee, your brain releases a substance called Brain-Derived Neurotrophic Factor (BDNF), which supports the powerhouse of your muscles
BDNF acts on certain neurons of the central nervous system and the peripheral nervous system, helping to support the survival of existing neurons, and encourage the growth and differentiation of new neurons and synapses, thereby improving your brain health
