With the increasing deterioration of the environment, floods, droughts, tornadoes, tsunamis, earthquakes and other natural disasters are high; mining accidents, traffic accidents and other human disasters appear frequently, and their severity, the scope of harm also has the potential to expand. In the face of various natural disasters, the resistance of human beings seems so weak. In the face of disasters, people not only suffer from huge property losses and the grief of the death of loved ones. Therefore, people who have experienced it are often anxious, depressed, easily agitated, have nightmares, and have behavioral withdrawal, which is called post-traumatic stress disorder. Post-traumatic stress disorder refers to the intense fear, helplessness, or panic after experiencing, witnessing, or encountering a catastrophic event (the event involves real death or the threat of death, the existence of serious physical injuries, endangering one’s own life or the lives of others). This is followed by recurrent flashbacks to the event and lingering memories; recurrent distressing dreams about the event; specific behavioral or emotional reactions as if the traumatic event were happening again (dissociative flashbacks); sensitivity to sound and light, often jumping at the slightest sound; intense psychological distress when exposed to information related to the traumatic event Once exposed to information related to traumatic events, there will be strong psychological pain; when exposed to information related to traumatic events, there will be physiological reactions (panic, chest tightness, trembling, etc.). Also try to avoid thoughts, emotions and speech related to the traumatic experience; try to avoid activities, places or people that remind them of the traumatic event; cannot recall an important aspect of the traumatic experience; have significantly less interest in some important activities or participate in them less frequently. Feeling distant or disconnected from others; limited range of emotional responses; impaired sense of future (lack of expectation for the future). Difficulty sleeping or sleep disturbance, irritability or anger attacks, difficulty concentrating, increased level of alertness, increased startle response. Decreased appetite and weight loss. The causes of traumatic stress disorder are related to the severity of the event, the individual’s tolerance and cognitive evaluation (over-amplification of the disaster, over-imagination of the consequences of the disaster, etc.). When encountering a disaster, the occurrence of traumatic stress disorder can be greatly reduced if psychological intervention is received in time, and once traumatic stress disorder occurs, psychotherapy and medication can stop the deterioration of the condition and promote recovery.
