Hypervigilance and hyperarousal are related concepts, but they are not the same thing. Hypervigilance is a state of heightened awareness and suspicion, in which a person is constantly on the lookout for potential threats or dangers. This can lead to excessive worry and anxiety, as well as physical symptoms such as difficulty sleeping, irritability, and difficulty concentrating.
Hyperarousal, on the other hand, is a state of increased physiological activity, such as a rapid heartbeat, high blood pressure, and rapid breathing. It is a common symptom of anxiety and stress, and can also be a side effect of certain medications or substances. Hyperarousal is often accompanied by feelings of anxiety and fear, and can lead to difficulty sleeping and other physical symptoms.
While hypervigilance and hyperarousal are related, they are not the same thing. Hypervigilance is a psychological state, while hyperarousal is a physiological state. However, the two can occur together, and may be experienced by people who are suffering from anxiety disorders, post-traumatic stress disorder (PTSD), or other mental health conditions.
