Psychological Factors
Numerous psychological factors contribute to irritability. Often, when an individual encounters a particular situation, they may react with heightened anger and frustration, which typically stems from underlying anxiety and stress. The intensity of irritability tends to increase in proportion to the pre-existing levels of anxiety and tension experienced by the individual.
Individual Factors
Individual factors refer to personal characteristics unique to each person. These may include traits such as frustration, narcissism (or self-centeredness), and a diminished capacity for forgiveness. A pertinent example is the irritability displayed by a narcissistic racer who exhibits annoyance if others compete in a car race, firmly believing in their own superiority.
Physical Factors
Anger and irritability can severely impact interpersonal relationships, often stemming from various physical health issues, including cardiovascular diseases and hypertension.
Mood Disorders
Mood disorders can provoke irritability in people, particularly when they feel treated unjustly and are unable to act against such treatment. This is compounded by interactions with individuals who show indifference to the feelings, possessions, or authority of others.
Hormonal Disorders
Elevated testosterone levels in men, beyond normal ranges, can lead to increased irritability, aggression, and outbursts of anger. High testosterone levels can also exacerbate feelings of depression, accompanied by insomnia, weight fluctuations, muscle pain, and other health-related issues.
Unhealthy Diets
Consuming unhealthy foods is linked to increased aggression and irritability in children. This dietary choice can lead to several health issues, including hyperactivity, depression, and mood swings. Certain foods may contain flavor-enhancing additives like monosodium glutamate and caffeine, which can trigger adverse reactions. Moreover, children consuming allergenic foods may experience increased anger, hyperactivity disorders, and attention deficits. These behavioral issues can potentially be mitigated by incorporating foods rich in omega-3 fatty acids, such as walnuts, fish, and canola oil, into their diets.
