The actual action mechanism of caffeine includes an intricate phenomenon. In this process your brains secretes ‘Adenosineâ€￾ chemical compound when it is tired and desires some rest. The chemical compound released by brain passes to significant cells known as receptors, where it undermines chemical functioning avoiding further stimulation of brain. When you consume caffeine through any source, it imitates the secreted chemical adenosine so that it can mimic its purpose at the receptors but do no have any counteracting effect of adenosine. It does not allow adenosine to pass through and undermine the functioning of chemical which stimulates your brains but in fact it builds up stimulants. This keeps your brain invigorated as the signals to slow down is not passed.
