Polyphasic Sleeping is the practice of sleeping more than once throughout the day. This is in contrast to monophasic sleep which is sleeping once like most people do.

### Pros
The main benefit of polyphasic sleep is that you can spend less time sleeping to gain the same amount of rest.

For example, a popular sleeping pattern is called Everyman 2:

* Base sleep 4 hours 30 minutes
* 2x 20 minute naps
* For at total of 5 hr 10 minutes

People can live on 5 hr 10 minutes of sleep!

Having more time itself leads to a variety of benefits:

* More time for hobbies
* Adenosine levels are reset more than once a day -- a compound that helps with mental clarity.

### Cons
* May lead to sleep deprivation
* Cognitively and physically impaired
