Hypervigilant:
Very aware/tense/easily startled state
Hypervigilance is an
anxious/
expectant state. People who are hypervigilant (
tense/
nervous/awaiting
danger/expecting
attack) are that way for a reason.
Typically hypervigilance is present in an individual because of past
trauma, like
Vietnam vets and abused people for example.
A lot of times, hypervigilant people have
rigid postures and taught
muscles from being tense all the time.
Constant
anxiety and watching of one's surroundings is tiring.
