Sleep deprivation is the condition of not having enough sleep; it can be either chronic or acute. A chronic sleep-restricted state can cause fatigue, daytime sleepiness, clumsiness and weight loss or weight gain. It adversely affects the brain and cognitive function. However, in a subset of cases sleep deprivation can, paradoxically, lead to increased energy and alertness and enhanced mood; it has even been used as a treatment for depression (see below). Few studies have compared the effects of acute total sleep deprivation and chronic partial sleep restriction.
Effects of sleep deprivation compound across nights: Four or more nights of partial sleep deprivation containing less than 7 hours of sleep per night can be equivalent to a total night of sleep deprivation. A single night of total sleep deprivation can affect your functioning for up to two weeks. To your brain, sleep is money and the brain is the best accountant. According to Circadian, when you have sleep-deprived or fatigued workers, productivity levels and quality of work will be compromised.
