Sleep Deprivations


Sleep deprivation is something that everyone has been through, for example for the holiday season, but our sleep debt is then quickly recovered by a sleep increased slightly (or depth) on the following days.


Deprivation of sleep-time or part is more or less well supported by the person experiencing it, but the effects will mainly depend on its activity the next day. Indeed if the day is active with manual activities continue, then the deprivation does not feel too active since the body will prevent sleep (Harvey & Kennedy, 2002).

The Concept of Sleep

Sleep is essential to life and plays a role in many physiological and psychological functions such as tissue repair, growth, consolidation of memory and learning. Although sleep needs vary from one adult to another, experts believe that sleep deprivation regularly (less than 7 hours per night) over time may have adverse effects on the brain and body. The urge to sleep is characterized by various signs: yawning, rubbing eyes, decreased attention, fuzzy thinking. The individual takes a sleeping posture that varies according to room temperature (in a ball in cold, warm elongated) (Stores, Stores & Buckley, 2006).

The effects of sleep deprivation are mostly felt in certain slots and their appearances and intensities are increasing during total sleep deprivation; include: hallucinations, nervous laughter, delirium, decline of intellectual faculties, irritability/aggression (Harvey & Kennedy, 2002).

Sleep deprivation in depression

A disturbed sleep patterns and problems with falling asleep and sleeping is one of the very typical symptoms of a depressive disorder. This is especially true in the forms of depression, the stronger with a biological predisposition (tendency) for recurrent or associated chronic depressive episodes, or as a seasonal course exhibit. On the other hand, lack of sleep and sleep adverse conditions certainly acute phases of illness of a number of mental disorders (eg bipolar disorder, schizophrenia) trigger (Harvey & Kennedy, 2002).

Therefore, it may seem surprising at first that you can incorporate as a non-pharmacological treatment option a selective sleep deprivation (wake therapy) in the treatment of depression. Due to the change in sleep-wake rhythm in the brain changes are ...
