Does caffeine cause irritability?

  1. True

  2. False

The correct answer is: True

Caffeine has been known to have a direct effect on an individual's mood, resulting in increased irritability. This is because caffeine is a stimulant that can cause a spike in adrenaline and cortisol levels, leading to feelings of anxiety, restlessness, and irritability. Additionally, regular caffeine consumption can also lead to dependency, causing adverse effects on mood when not consumed. Therefore, it is safe to say that caffeine does cause irritability, making option A the correct choice. Option B is incorrect because studies have shown a clear correlation between caffeine consumption and irritability, so it is not false that caffeine can cause irritability.
