When you touch something hot, your body reacts before your brain feels pain.
This happens because of a reflex arc.
Sensory neurons send signals directly to the spinal cord, which instantly sends a motor response to pull your hand away.
Only after this action does the pain signal travel to the brain.
This built-in delay exists to protect your body from serious injury.
