Lets put links to all of these and group them in sections (body, then mind).

Also let's talk a little about what sleep does so they understand the inner workings.

"We are still unsure about why we need sleep but getting it is essential to function our best everyday. From the time that we wake up, our brain is wanting to go back to the sleeping state. This is called sleep pressure. At the time of wake, we release a burst of cortisol and acetylcholine spiking our heart rate and activating our senses and muscles. This gets us into motion.

Over the day a toxins build up creating plaques in our brains, similar to plaque on our teeth. Additionally, we are creating new neurons with all of the new information that we are taking in. When we fall asleep, spinal fluid enters the brain and clears out these plaques. Then proteins actually breakdown the unnecessary neurons creating space for new ones to grow the next day, while strengthening the connections of the newer important neurons by replaying the patterns we learned during the day throughout the night. (the importance of the neurons is likely attached to the frequency of the information studied and the emotional state of the body at the time of learning the new information - see episodic memories).

As these toxins build up, the brain feels more and more pressure to go to sleep. But from the time we wake up, we have a different neural network that is applying a greater force enabling us to stay awake - it is called the wake network. This wake network is like a symphony conductor for your waking brain which integrates many different areas of your brain, originating out of the hippocampus, in specifically hypocretin cells (people with narcolepsy are missing these cells). This network is turned off by melatonin, which is secreted

Where are these stats? Let's get the source material and hyperlink to them.
