Sleeping in the first 24 hours after a traumatic event may help people to process the memory more effectively and therefore minimize the symptoms of post-traumatic stress disorder, according to research published in the journal Sleep.
Avoiding a person, event, or object related to the experience, or refusing to think about anything associated with it
Arousal and reactivity symptoms, such as feeling easily startled, tense, or being unable to sleep
Symptoms that affect cognition and mood, such as loss of interest in things the person usually enjoys, or distorted feelings of guilt
If the effects interfere with work or relationships, this indicates that the person has PTSD. Children will have slightly different signs and symptoms.
The symptoms of PTSD do not necessarily emerge straight away. They may start to develop 3 months or even a year after the event.
