Irritability is defined as an excessive sensitivity or impatience to inconvenience, annoyance, or slight provocations. It refers to a propensity to experience feelings of annoyance, frustration, or anger in response to often minor external stimuli. Some key characteristics of irritability include:

  • Feeling easily annoyed or angered by minor frustrations
  • Overreacting emotionally to trivial matters
  • Having a low frustration tolerance threshold
  • Experiencing mood changes frequently
  • Feeling constantly on-edge
Irritability differs from anger in that it tends to be a reaction to smaller, everyday stressors and hassles rather than major upsetting events. It is a common symptom or feature associated with several medical, psychological, and psychiatric conditions, including:
  • Depression - Irritability, frustration, and mood lability are hallmark symptoms
  • Anxiety disorders - Feeling constantly nervous or "on-edge" can manifest as irritability
  • ADHD - Difficulty with impulse control and emotion regulation
  • PTSD - Increased arousal and sensitivity to potential threats
  • Chronic stress - Cumulative effects of stress can reduce one's resilience
In many cases, irritability arises in tandem with feeling overwhelmed, fatigue, trouble concentrating, sleep disturbances, and other issues that tax daily functioning and coping capacities. Treating an underlying condition can often help reduce irritable moods and behaviors. Additional strategies include:
  • Stress management and self-care practices
  • Cognitive-behavioral therapy to modify reactions
  • Communication skills training
  • Medications in some instances
While everyone feels irritable from time to time, experiencing frequent or intense feelings of frustration, annoyance, and anger can negatively impact relationships, school/work performance, and overall well-being. If irritability persists and causes impairment, seeking professional support is advised. With proper diagnosis and treatment, as well as implementation of positive coping strategies, irritability can often be managed effectively.
