What is one effect of excessive caffeine consumption on pilots?

Excessive caffeine consumption can lead to increased anxiety, which is particularly concerning for pilots. Caffeine is a stimulant that affects the central nervous system. When consumed in large quantities, it can exacerbate feelings of restlessness and anxiety, which are not ideal in high-stakes environments like aviation. This heightened anxiety may also disrupt sleep quality, leading to insomnia or decreased restorative sleep. Sleep deprivation can have significant implications on a pilot's ability to perform effectively, as it affects cognitive function, decision-making, and overall performance in the cockpit. Understanding the impact of caffeine on anxiety and sleep is critical, as maintaining optimal mental health and alertness is essential for safe flying.
