Caffeine fills the receptors in your brain that adenosine would fill, and that when filled naturally it tells your brain that you have been awake for a while and need to sleep. So caffeine really helps to prevent feeling tired.
(A side note, but I think that it is so damn cool how that works: ATP, adenosine triphosphate, is processed releasing the “phosphate” part to be use in the energy cycle and the adenosine that is left over is kinda used like a record of how much energy you’ve processed, so after a while of processing energy you naturally have a way of saying “I should rest now.” Caffeine blocks that from happening for a while.)
Sugar eventually is processed as glucose which is just straight up energy for your brain, so that helps when you’re already tired and need a kick in the pants.
I’m just a nerd for science so I might have some of the details messed up, but from what I remember this is kinda how it all works.
Coffee has no calories. Red Bull is full of sugar which is actual energy.
I love coffee, but sometimes sugar is more effective than just caffeine
It all depends on the time you consume it.
