Caffeine is the most widely consumed psychoactive drug in the world. Around ninety percent of the world’s population drinks caffeine regularly; yet, there is a lack of knowledge about how the substance affects our minds and bodies. There are many areas in which caffeine affects our daily lives. From regulating circadian rhythms in adults to providing valuable nutrients for our bodies, caffeine is incredibly beneficial for overall health--if used properly. By understanding how caffeine affects our physical and mental health, those who drink coffee, tea, energy drinks, and sodas can adequately utilize the drug daily to promote longevity and an overall good quality of life.
