What can excessive caffeine consumption lead to?

Excessive caffeine consumption can lead to heightened tolerance and dependence because the body adapts to the large amounts of caffeine over time. As an individual consistently consumes high doses of caffeine, their sensitivity to its effects may diminish, requiring ever-increasing amounts to achieve the same stimulating effects. This can create a cycle where the person feels the need to consume caffeine regularly to avoid withdrawal symptoms, which can include fatigue, irritability, and headaches. This dependence can have implications for an individual's overall health and wellness, as they may struggle with decreased energy levels when not consuming caffeine and may need to manage their intake carefully to prevent negative side effects.

The other choices do not accurately represent the effects of excessive caffeine. While it is true that caffeine can affect recovery rates and muscle development to some extent, excessive amounts do not necessarily lead to improved results in these areas and can actually be detrimental to health. Additionally, increased nutritional absorption would not be a result of excessive caffeine consumption; rather, caffeine can sometimes hinder the absorption of certain nutrients.
