Does your body and brain shut down while sleeping?

Early neuroscientists assumed that consciousness wanes during sleep because the cortex simply shuts off. But electroencephalography (EEG) and other modern methods have since ruled out that explanation, showing that the electrical chatter and metabolism of neurons in the cortex continues unabated during sleep.

How does your body wake itself up?

The SCN is located in the hypothalamus. The SCN is sensitive to signals of dark and light. The optic nerve in your eyes senses the morning light. Then the SCN triggers the release of cortisol and other hormones to help you wake up.

Between the times of 10:00 pm and 2:00 am the body goes through a dramatic process of physical repair. Between roughly 2:00 am and 6:00 am the body will go through a process of psychological repair. A disrupted sleep pattern will cause the Cortisol to elevate and negatively affect the regenerative process.

Is your brain awake when you sleep?
