Caffeine is a legal and non-regulated psychoactive drug that is consumed across the world and most commonly in coffee, cola-like beverages, chocolate, and energy drinks. The stimulating effect of caffeine gives an individual a boost of energy as well as fighting drowsiness which is why the body will sometimes crave an afternoon coffee or energy drink after a long morning. While many have a daily dose of caffeine across the world, in coffee or otherwise, these same people may not be aware of the various effects caffeine has on the human body. These seven incredible ways in which caffeine affects the body are sure to shock and surprise.
Caffeine can get into the bloodstream very quickly making its presence within the body felt almost instantly. Many who are reading this would have experienced a morning in which tiredness has seemingly overtaken the body, leaving an individual in a zombie-like state. After a morning cup of coffee, the ‘zombie’ awakens and can pump out morning emails and tasks and become a productive human once again. Adenosine, a neurotransmitter in the body, can play a role in making a human sleepy and caffeine will ‘block’ this type of activity within the nervous system. An increased feel of alertness after a coffee or energy drink will be most noticeable for those who experience an afternoon dip in energy, those who work at night and in dangerous jobs, and those suffering from a cold or flu. Habitual coffee drinkers may need 2 or 3 cups of coffee to experience the same alertness as someone who does not consume coffee or caffeine as regularly.
