Hypervigilance is a term used to describe the state of being constantly on high alert. If you are hypervigilant, you may be constantly scanning your environment for possible threats, even when there is no real danger present. This can be very taxing and lead to a number of negative consequences.
Post-traumatic stress disorder (PTSD) is a mental health condition that can occur after you have experienced or witnessed a traumatic event. The event may have been violent, such as an assault, or terrifying, such as a natural disaster or car accident.
PTSD symptoms in men can include flashbacks of the event, avoidance of reminders of the event, anger, irritability, and difficulty sleeping. Men may also feel detached from friends and family, or be more aggressive than usual.
