The Physiology of Pain: Why We Feel It and How Our Body Responds

Описание: The Physiology of Pain: Why We Feel It and How Our Body Responds
Pain isn’t just a “damage meter.” It’s your body’s alarm system—designed to protect you. In this video, we break down how pain signals travel, how the brain interprets them, and why chronic pain can feel intense even when tissues have healed.

In this video, you’ll learn:

Why pain is protective—and what happens when people can’t feel it

The journey of a pain signal: transduction, transmission, perception, and modulation

Why “fast pain” and “slow pain” feel different

How Gate Control Theory explains why rubbing a sore spot can reduce pain

How the nervous system can become more sensitive over time (central sensitization)

Why chronic pain can become a “stuck alarm” (false alarms vs real danger)

A healthier way to interpret pain signals and reduce fear around them
