Sleep deprivation 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.

Chapter 4 Sleep deprivation's effects. When deprived of sleep, people have trouble paying attention to tasks and solving problems (Mullington & others, 2009).

Sleep Deprivation During total sleep deprivation, the brain accumulates sleep debt at a rapid rate, and energy use is high – so high that the animal or person loses weight. In the more common situation of partial sleep deprivation – chronic insufficient sleep – the rate of extra energy expenditure is low and the body can accommodate.

10 Negative Effects Of Sleep Deprivation Increased Risk For High Blood Pressure. Because your stress hormone levels are high from lack of sleep, this puts you at a higher risk of developing high blood pressure, or hypertension. In fact, some studies have shown that a lack of sleep can affect your blood pressure within 24 hours. Over the long-term, this can lead to heart disease. So if you’re getting less than six hours of sleep per night, your chance of developing high blood pressure has greatly increased.
