When one is in danger it is known that one experiences fear. This level of fear triggers split second preparation for the body to defend itself against the danger. The "fight or flight" response is a normal healthy reaction meant for the body's protection but in post traumatic stress disorder this particular reaction is damaged and changed where a PTSD patient actually gets more stressed and frightened even when there is no danger.
PTSD develops usually after a extremely terrifying event that involved physical or mental harm and could be in the form of occuring to a loved one or being a participant in a harmful event. PTSD can be caused by a variety of traumatic incidents such as war, plane crashes, accidents, natural disasters, rape, bombings, abuse, kidnapping or hostage situation.
Some of the signs and symptoms of PTSD can be bad dreams, frightening thoughts, flashbacks, avoidance, or hyperarousal.
In recent discoveries it has been found that cannabidiol (CBD) can reduce anxiety, pacifies the nervous system and induces a state of relaxation without the challenging affects of THC on the psyche.
