Unlike sleep deprivation, people with short sleep syndrome (SSS) regularly need fewer than six hours of sleep per night and can still function normally.

There's a great argument that the Marine Corps has the hardest military training of anyone, and here's why.

The majority of people enjoyed a biphasic sleeping pattern in which they would sleep for approximately four hours early in the night (a period dubbed “first sleep”), wake up for an hour or so (during which time they might reflect on their dreams, catch up on household chores, have sex, or simply relax), and then head ...
Our body clock naturally lends itself to the siesta because of a reduction in alertness in the early afternoon.
