Document Summary
Introducing sleep: most people sleep over 175,000 hours in their lifetimes. This can vary between people, depending on their sleep habits.

Donkeys may only sleep 2-3 hours per day. Humans fall near the lower end of the spectrum, sleeping an average of 6-9 hours per night: non-terrestrial mammals (whales, seals, walruses etc. ,) have unusual sleep patterns. In certain cases, their version of sleep happens one hemisphere at a time. Species differences in sleep patterns is our first hint that there is more going on during sleep than just rest. Stages of sleep: early researchers studying the brain during sleep made two interesting discoveries, 1.
