The progression of the sleep deprivation experience can be broken down into hours gone without sleep, excluding micro-sleep sessions which may occur. A microsleep is a short period of time, from 10 to 60 seconds, in which the brain enters a sleep state, regardless of what the person is doing at the time. The affected individual often is not aware of the occurrence of the microsleep, experiencing only a brief skip forward in time.<ref>Coren S (March 1998). "Sleep Deprivation, Psychosis and Mental Efficiency". Psychiatric Times. 15 (3) http://www.psychiatrictimes.com/login?referrer=http%3A//www.psychiatrictimes.com%2Fsleep-deprivation-psychosis-and-mental-efficiency</ref>. While humans are physically capable of surviving extended periods of sleep deprivation, it becomes increasingly difficult to remain awake and alert, until the person is inevitably unable to consciously resist falling asleep. | The progression of the sleep deprivation experience can be broken down into hours gone without sleep, excluding micro-sleep sessions which may occur.

The effects of [[sleep deprivation]] intensify as one is subjected to more time without sleep. Up to the 24-48 hour mark, the cognitive effects are manageable and perceptual effects are limited to the peripheral vision and hearing of the sufferer. However, as time goes on, the effects become all consuming and can render normal life impossible. | The effects of [[sleep deprivation]] intensify as one is subjected to more time without sleep.

Sleep deprivation effects are expressed differently through populations including but not limited to age, gender, and occupation<ref>Alhola, Paula; Päivi Polo-Kantola (October 2007).

Keeping this in mind, people will have different reactions to different levels of sleep deprivation. | Sleep deprivation effects are expressed differently through populations including but not limited to age, gender, and occupation<ref>Alhola, Paula; Päivi Polo-Kantola (October 2007).
