Review Questions

• How does irritability manifest physiologically and psychologically in individuals under stress?
  • Under stress, irritability can manifest physiologically through increased levels of stress hormones like cortisol and adrenaline, leading to heightened arousal and reactivity. Psychologically, individuals may experience racing thoughts, heightened anxiety, and a decreased tolerance for frustration. This combination can result in explosive reactions or mood swings when faced with even minor provocations.
• What role does nicotine play in influencing irritability among users, particularly during withdrawal?
  • Nicotine significantly affects the brain's neurotransmitter systems, primarily through the release of dopamine. In users, withdrawal from nicotine often leads to increased irritability as the brain adjusts to the absence of this stimulant. The lack of nicotine can cause a drop in mood and heightened sensitivity to stressors, making users more prone to agitation and frustration during this period.
• Evaluate the potential long-term implications of chronic irritability on an individual's mental health and social relationships.
  • Chronic irritability can have serious long-term implications for both mental health and social relationships. It is often associated with mood disorders like anxiety and depression, which can further exacerbate feelings of frustration and emotional instability. In social contexts, persistent irritability may lead to conflicts with friends or family members, resulting in isolation or a breakdown of relationships. Ultimately, addressing chronic irritability is essential for improving overall well-being and fostering healthier interactions.
