Caffeine happens to be everywhere around you. But how exactly does it work?

How caffeine works

Caffeine takes away the sleepiness after its ingestion. But how exactly does this occur?

When you take a portion of coffee, the caffeine content in it serves as an antagonist of the adenosine receptor. The adenosine is the body substance that helps you to feel sleepy. The caffeine does a job of intercepting the adenosine, shielding you from feeling sleepy.

Caffeine has a quick reaction in the body system. It takes 30 to 60 minutes for it to reach a peak in your blood. Half-life of caffeine in the body is 3 to 5 hours. The other half would remain in your system for a longer period of time.

​Foods and drinks that contain caffeine

Caffeine is found in a lot of things people love to eat or drink. Asides coffee, it can also be found in tea, chocolate and energy drinks.

Your favorite Expresso contains around 250mg of caffeine per 250ml, coffee contains approximately 200mg in 250ml, while energy drinks can contain between 50 to 160mg. Dark chocolate could contain as high as 35mg.

​​Benefits​ of caffeine
