Although there is considerable variation among individuals, research indicates that most people need between seven to nine hours of quality, uninterrupted sleep every day. Missing sleep for even a single night (“acute sleep deprivation”) can make you fatigued. After several nights of missed sleep (“chronic sleep deprivation”), the effects will be more severe, and may be long-term.
Sleep deprivation are of two kind; Acute Sleep Deprivation and Chronic (or Cumulative) Sleep
Deprivation. Acute Sleep Deprivation is caused be getting insufficient sleep for one night. For example: getting only five hours of sleep because you stayed awake to care for a sick family member. Acute Sleep Deprivation can also result in short-term “sleep debt” which can be easily cancelled out by getting enough sleep the next night.
Chronic (or Cumulative) Sleep Deprivation is caused by: getting insufficient sleep on a regular basis. Example: never getting more than six or seven hours of sleep because you work an early shift but go to bed late. Chronic (or Cumulative) Sleep Deprivation can results in accumulated “sleep debt”, which is more difficult to cancel out – studies show that, after two weeks of chronic (cumulative) sleep loss, you will perform as though you had been continuously awake for 24 to 48 hours.
Did you know that you are at greater risk for fatigue when you don’t follow your body’s natural biological rhythm?
Virtually all of our bodily functions are timed according to a 24 hour cycle known as your “circadian rhythm” (or “body clock”). The circadian rhythm is influences by external cues (such as sunrise and sunset). In turn, it influences your body’s temperature, digestion, and hormone production, as well as your patterns of sleep, wakefulness, and alertness.
