How does caffeine actually work? Why do people get even more tired after they stop using it after a while?
In: Biology
Shorter version of the wall of text:
Caffeine blocks a chemical in your head that tells you you’re tired. It fills the parking spot in a neuron this chemical normally uses, so until it wears out, you will artificially not feel tired.
As times goes on, more receptors of the tiredness chemical are made available, more caffeine is needed to block them and eventual withdrawl causes much more of the tiredness signaling chemical to be applied at once.
