Do you behave aggressively without knowing the reason? Read this

In some situations, aggressive behaviour might arise based on certain underlying causes, such as stress, tiredness, hormonal imbalances, or psychiatric conditions like anxiety or depression.
A recent research addressed the question of several reasons behind aggressive behaviour without a clear cause. A study in Neuroscience News pointed out how aggression sometimes does not result from losing control but rather is something planned or the result of impulsivity in response to stress.
According to this theory, extreme emotional states become reasons for the brain to adapt to situations because this may make the individual perform an impulsive aggressive act without awareness of the roots.
Underlying factors that contribute to aggressive behaviour

Stress and frustration
Stress at work or personal difficulties can cause irritability and aggressive reactions. Overwhelmed or coping-less feelings tend to make people lash out impulsively. It is found through research that intense stress provokes emotional reactivity, which in turn can take the form of aggression.
Hormonal imbalances
According to the World Health Organization, high levels of or fluctuating ranges of testosterone are linked to such behaviours as irritability, impulsiveness, and aggression. On a related note, the research also showed that in the case of unregulated or high testosterone levels, it leads to increased responses of aggression.

Abuse
Alcohol, drugs, or withdrawal from some substances also lowers inhibitions and impairs judgments, making one aggressive. A study in the Journal of Studies on ‘Alcohol and Drugs’ explores how alcohol consumption contributes to aggressive behaviours, especially regarding domestic violence and social conflict.
Social triggers
The experiences of abuse, violence, or neglect during childhood could be correlated with a long-term impact on emotional responses, leading to the individual becoming vulnerable to aggressive behaviours in later life. The WHO reports on ACE trace a connection between childhood abuse and neglect and increased aggression, substance abuse, and even crime in adult life.
Genetics
Some studies suggest genetic liability in aggression. However, the connection is not deterministic as some genetic markers do predispose people to an aggressive style of response, which increases especially when stressors are concerned with the environment environment. The study ‘Genetic and Environmental Contributions to Aggression’ by McDermott explains how both genetic elements and environmental factors contribute to aggressive behaviour.
