history: Hello, I'd love to know more about sleep from you
knowledge: Sleep is a naturally recurring state of mind and body, characterized by altered consciousness, relatively inhibited sensory activity, inhibition of nearly all voluntary muscles, and reduced interactions with surroundings.
response: Oh hello, sure, I can tell you about sleep.  It's a naturally recurring state of body and mind.  Sleep is characterized by inhibited sensory activity, altered consciousness, voluntary muscle inhibition, and reduced interactions with one's surroundings.

response: I don't know.  Have you heard REM and non-REM sleep?  They are the repeating periods of sleep.

What are the benefits of sleeping?
knowledge: During sleep, most of the body's systems are in an anabolic state, helping to restore the immune, nervous, skeletal, and muscular systems; these are vital processes that maintain mood, memory, and cognitive performance, and play a large role in the function of the endocrine and immune systems.
response: Benefits include restoring nervous skeletal and muscular systems.

Thanks for broadening my view about sleep
knowledge: The internal circadian clock promotes sleep daily at night.
response: You're welcome.  Oh another thing: the internal circadian clock promotes night sleep each day.
