What neurotransmitter does coffee influence?

Here's how it works:

* Caffeine blocks adenosine receptors: Adenosine is a neurotransmitter that promotes sleepiness. When caffeine blocks these receptors, it prevents adenosine from binding and triggering drowsiness.

* Increased dopamine release: This blockage of adenosine receptors indirectly leads to increased dopamine release. Dopamine is associated with feelings of pleasure, motivation, and reward.

* Other neurotransmitters: While dopamine is the most significant, caffeine also affects other neurotransmitters like norepinephrine and serotonin, contributing to alertness, focus, and mood elevation.

In summary: Coffee's effect on dopamine is a major contributor to its stimulating effects and the feeling of alertness and focus it provides.
