• Caffeine and the Nervous System: Coffee contains caffeine, a stimulant that can increase alertness by triggering the central nervous system. While moderate amounts improve focus, high intake may overstimulate the nervous system, leading to irritability and jitteriness.

• Research on Mood Changes: Multiple studies indicate that consuming large amounts of caffeine can contribute to mood swings, restlessness, and feelings of nervous tension. Individuals who are sensitive to caffeine are particularly prone to these effects.

• Sleep Disruption Effects: Excessive coffee intake can interfere with sleep patterns. Poor sleep increases stress and irritability, creating a cycle where more coffee is consumed to stay awake, further intensifying jitteriness and anxiety.

• Heart Rate and Anxiety Symptoms: High caffeine intake may cause temporary increases in heart rate and blood pressure, which some people perceive as anxiety or nervousness. These physical reactions can make someone feel jittery and emotionally unsettled.

• Scientific Evidence: A 2017 study published in Frontiers in Psychiatry found that higher caffeine consumption was associated with greater self-reported anxiety and irritability in adults. Similarly, research in the Journal of Psychopharmacology noted that caffeine can exacerbate stress responses, especially in people prone to anxiety disorders.

• Individual Sensitivity Matters: Everyone reacts differently to caffeine. Factors such as age, metabolism, genetics, and existing anxiety levels influence how coffee affects mood and behavior.

Conclusion:
Scientific research supports that high coffee intake can lead to irritability, jitteriness, and heightened anxiety in sensitive individuals. Being mindful of caffeine consumption and choosing moderate intake can help reduce these effects.
