Caffeinated:

Being caffeinated means your body is under the temporary influence of caffeine, a natural central nervous system stimulant that increases alertness and delays fatigue. It is the most widely consumed psychoactive substance in the world, usually taken through coffee, tea, sodas, and energy drinks. How it Works in Your Brain

Blocks Adenosine: Caffeine mimics a chemical called adenosine, which naturally builds up in your brain during the day to make you feel sleepy. Caffeine docks into adenosine receptors, blocking them so you cannot feel the fatigue.

Triggers Excitatory Chemicals: By blocking adenosine, caffeine allows other stimulating neurotransmitters—like dopamine, norepinephrine, and adrenaline—to flow freely, improving your focus and mood. Common Physical Effects
