It starts with a sensation.
A racing heart.
Dizziness.
A headache that feels “different.”
Then your brain goes:
“Is this serious? Do I need the hospital?”
That’s the amygdala hijack.
When your brain detects threat, it activates fight-or-flight before logic has time to weigh in. In health anxiety, normal body sensations get misinterpreted as danger.
The more you monitor your body, the more you notice.
The more you notice, the more anxious you feel.
Sensation → Catastrophic thought → Adrenaline → More sensation.
Health anxiety isn’t dramatic.
It’s a nervous system stuck on high alert.
And it’s treatable.
