For this reason, human beings are not turning their heads when they are tired and they feel tired. However, since caffeine invades the brain and adheres to the adenosine receptor, adenosine can not stick to the receptor no matter how tired it becomes, it becomes impossible to feel fatigue and it is an illusion that energy has overflowed That's it. The state of arousal by caffeine, which depends on the age and height of the person who ingested, usually lasts for 4 to 6 hours.

Eating daily caffeine with awakening effect results in a change in the chemistry and physical properties of the brain. The most striking change occurring in the brain due to the regular use of caffeine is that the brain cells produce more adenosine receptors to match the number of adenosine deprived of the receptors to be contained. For this reason, people who frequently take caffeine will not be able to obtain the awakening effect that many would want to take more caffeine to block the adenosine receptors produced.
