**Psychology of war** is one of the important and lesser-known topics of mental health, which plays an essential role in the analysis of behavioral reactions, mental disorders, and the deep consequences of war on people's lives. Many think that war only means loss of life or home, but the reality is more bitter than these words. The psychological effects of war remain with individuals, families and even generations after the end of the conflict. But how can we put these hidden wounds and fear of war in the path of treatment and mental health with the psychology of war? **What is the psychology of war and why is it important?** The Psychology of War examines the mental, emotional and behavioral reactions of humans in the conditions of war, after war and even when faced with news of crisis and threat. This branch of psychology examines the short-term and long-term consequences of war for survivors, soldiers, refugees, and even society as a whole. According to the researchers, understanding the psychological processes of war can help prevent and treat trauma, chronic anxiety, treat depression and other mental health challenges. **The most important psychological effects of war on humans** The psychological and emotional effects of war are very deep and multidimensional. The psychology of war explains that after the end of any major crisis, humans usually experience symptoms that each require attention and treatment. The most important psychological injuries of war are: - **Post-traumatic stress disorder (PTSD)** Post-traumatic stress disorder is the most common consequence of experiencing or witnessing violence and war disasters and is associated with symptoms such as nightmares, compulsive recall of the incident, fear response, anxiety and guilt. If these symptoms continue for more than a month and cause disruption in the normal functioning of a person's life, it is known as PTSD. PTSD treatment with neurofeedback is one of the methods used by specialists for this disorder. - **Depression and sense of emptiness** Post-war depression is extremely common among many survivors. Lack of motivation, deep sadness, reduced hope for the future and a feeling of emptiness are the usual symptoms of this condition. - Generalized anxiety and panic attacks People may suffer from constant worry and stress, insomnia, reduced concentration and even panic attacks. These symptoms can last for years. - **behavioral and social problems** Aggression, unpredictable behavior, use of drugs and alcohol, as well as withdrawal from the group are the behavioral consequences of war psychology. **Psychological effects of war on children and teenagers** In recent studies, it has been pointed out that children and teenagers suffer even more than adults from the psychological consequences of war. Severe fear, nocturnal urination, withdrawal, academic failure, recurring nightmares and even physical problems such as headache and heartache are important symptoms in this age group. War psychology suggests that families pay attention to the signs of children's behavior change and, if necessary, refer to a counselor or psychologist. **Methods to deal with and treat the psychological wounds of war** To heal psychological wounds caused by war, the following measures are recommended by war psychologists and experts: 1. **Cognitive-behavioral therapy (CBT)** One of the most effective treatments for PTSD and post-war anxiety is to help reframe negative thoughts and manage emotions. 2. **Teach coping skills with stress** Practicing meditation, deep breathing, physical activity and art therapy causes healthy emotional discharge and gradual return of mental peace. 3. **Family and community support** War survivors need a listening ear, non-judgmental understanding and ongoing support. Holding group therapy and awareness workshops is one of the important measures of war psychology. 4. **early specialized intervention** Rapid assessment and referral to a psychologist or psychiatrist will prevent problems from becoming chronic and increase the effectiveness of treatment. **The role of culture and media in increasing awareness about the psychology of war** Cultivating and informing about the facts and psychological consequences of war is very important. Public education, broadcast of documentaries, plays and interviews with survivors can be effective in resilience and reducing the negative label of mental illnesses. The psychology of war believes that if the society accepts the mental wounds of the survivors and accompanies them, the hope for treatment and return to a quality life will multiply.
