Some research suggests that species that face higher predatory risks sleep fewer hours than other species (Capellini et al., 2008), while other researchers suggest there is no relationship between the amount of time a given species spends in deep sleep and its predation risk (Lesku, Roth, Amlaner, & Lima, 2006). While it is probably the most commonly used drug in the world, the potency of this particular drug pales in comparison to the other stimulant drugs described in this section. Another theory regarding why we sleep involves sleeps importance for cognitive function and memory formation (Rattenborg, Lesku, Martinez-Gonzalez, & Lima, 2007). (credit a: modification of work by Todd Huffman), Psychedelic images like this are often associated with hallucinogenic compounds. This is similar to the kind of paralysis experienced by healthy individuals during REM sleep (Burgess & Scammell, 2012; Hishikawa & Shimizu, 1995; Luppi et al., 2011). Some sleep-deprived individuals have difficulty staying awake when they stop moving (for example sitting and watching television or driving a car).

Rotating shift workrefers to a work schedule that changes from early to late on a daily or weekly basis. The pons is important for regulating rapid eye movement (REM) sleep (National Institutes of Health, n.d.). The chapter will close with discussions of altered states of consciousness produced by psychoactive drugs, hypnosis, and meditation. (West et al., 2009, p. 114). While individuals suffering from sleep apnea may not be aware of these repeated disruptions in sleep, they do experience increased levels of fatigue. (2005) found that sleepwalking was not alleviated with the use of benzodiazepines.
