Facultative hibernators enter hibernation only when either cold-stressed, food-deprived, or both, unlike obligate hibernators, who enter hibernation based on seasonal timing cues rather than as a response to stressors from the environment. A good example of the differences between these two types of hibernation can be seen in prairie dogs.
Sleep on macOS consists of the traditional sleep, Safe Sleep, and Power Nap. In System Preferences , Safe Sleep [ 8 ] is referred to as sleep. Since Safe Sleep also allowed state to be restored in an event of a power outage , unlike other operating systems, hibernate was never offered as an option.
Obviously, the state that uses the least amount of power is a full shutdown, followed closely by “hibernate”—and trailed significantly by “sleep,” which uses the most power.
Sleep can follow a physiological or behavioral definition. In the physiological sense, sleep is a state characterized by reversible unconsciousness, special brainwave patterns, sporadic eye movement, loss of muscle tone (possibly with some exceptions; see below regarding the sleep of birds and of aquatic mammals), and a compensatory increase following deprivation of the state, this last known ...
States of suspended animation are common in micro-organisms and some plant tissue, such as seeds. Many animals, including large ones, may undergo hibernation, and most plants have periods of dormancy. This article focuses primarily on the potential of large animals, especially humans, to undergo suspended animation.

Hibernation (also known as suspend to disk, or Safe Sleep on Macintosh computers [1]) in computing is powering down a computer while retaining its state. When hibernation begins, the computer saves the contents of its random access memory (RAM) to a hard disk or other non-volatile storage. When the computer is turned on the RAM is restored and ...
