Hypervigilance
A state of heightened alertness where you constantly scan for threats, common in anxiety, PTSD, and after traumatic experiences.
What It Means
Hypervigilance is your nervous system stuck in threat-scanning mode. You're constantly monitoring your environment for danger—reading people's facial expressions, startling at noises, sitting with your back to the wall, unable to relax even in safe settings.
It's common in PTSD, generalized anxiety, and after any experience where your safety was compromised. Your brain learned that vigilance kept you alive, and now it won't turn off—even when the threat is gone.
Hypervigilance is exhausting. The constant scanning drains energy, disrupts sleep, makes social situations overwhelming, and keeps your stress hormones perpetually elevated. It's like running a security system at maximum sensitivity—everything triggers the alarm.
How This Relates to ILTY
ILTY helps you notice when hypervigilance is running and gently reality-test whether the current environment actually requires that level of alertness. Over time, conversations can help you build a sense of safety.
Example
You're at a restaurant but can't enjoy the meal because you're tracking every person who walks by, monitoring the exits, and reading your companion's micro-expressions for signs of anger. You're physically present but mentally on patrol. That's hypervigilance.
