Margaret J. King, PhD, director at The Center for Cultural Studies and Analysis, explains:
“Fear-facing releases powerful adrenaline and other hormone-based chemistry in the brain and body.
Facing fears (like public speaking) creates this natural high and can therefore become addictive.
It’s the fear effect that happens on a roller coaster, or other simulated risk-taking ride; there is a reason this capsule encounter draws fans who ride again and again.
For most of us, once or twice every decade is enough. We face down the discomfort of the thrill in order to benefit from its aftermath, which is a sizable release of endorphins.”
