Caffeine is so effective, the Olympics has restricted the amount of caffeine content you can have in your body during competition. That means it is a very powerful drug.
Most adults fein for the chance to drink another cup of coffee, because we are in a constant state of lethargy. Caffeine is affected, because it is able to block adenosine molecules from docking to the adenosine receptors in our brain. Adenosine is the molecule that naturally builds up in our brains throughout the day that makes us sleep. We are able to clear our these adenosine molecules while sleeping with the body’s glymphatic system.
