15. How does caffeine work in the human body? Next, it will be introduced in the form of a short story: there is a substance in the human brain called adenosine monophosphate, which only goes out to play with specific receptors. When adenosine monophosphate plays with certain receptors, people become drowsy. When caffeine appears, it sticks to the receptor and adenosine monophosphate cannot play with the receptor. When the pituitary gland sees this, it thinks it's an emergency and tells the adrenal gland to make adrenaline. In addition, caffeine can greatly increase people's dopamine levels. The end result is that you will fall into a state of caffeine-induced excitement!
