The Science Behind Exercise Fatigue: How Your Brain Protects You

The video explains that the pain experienced during exercise is not due to muscle fatigue but rather a self-preservation mechanism in the brain. Researchers from South Africa have identified a chemical called interleukin 6, which signals the brain to stop exertion to prevent muscle damage. This mechanism helps protect the body by encouraging rest before harm occurs.
