How Does Caffeine Work In Your Body?

To understand the effects of Caffeine on the human body, we need to first know how the human brain works.

As we work all day, our body generates ATP (Adenosine Triphosphate). One of the breakdown elements of ATP is Adenosine. Adenosine is generated in neural cells of the brain.

Our nervous system has Adenosine Receptors. Two types of Adenosine can be found in brain cells. A1A type Adenosine keeps you awake while A2A is responsible for sleepiness. As you continue to work throughout the day, A2A starts to increase.

This A2A Adenosine stimulates the receptors, causing your brain to slowly shut down to prevent overwork. Then you start feeling tired and get to sleep.

When caffeine enters your bloodstream and reaches your brain, it blocks the receptors and prevents the Adenosine to stimulate the receptors. Thus, you don’t feel any sort of tiredness or sleepiness. This helps you to focus, even more, makes you feel refreshed.
