Introduction
Most people view sleep as a passive state of 'turning off.' In reality, deep sleep is when the body's most powerful repair mechanisms are activated. Scientists have discovered a 'switch' in the brain that, during deep sleep, triggers a flood of growth hormones that build muscle and burn fat.
The Hormonal Cascade
This sleep switch is responsible for the 'brainwash' effect—clearing out toxic proteins like amyloid-beta—while simultaneously directing nutrient flow to muscle tissue for repair. This is why sleep is just as important as diet and exercise for physical and mental performance.
Frequently Asked Questions
