A large sleep debt may lead to mental or physical fatigue, and can adversely affect one's mood, energy, and ability to think clearly. There are two kinds of sleep debt: the result of partial sleep deprivation, and of total sleep deprivation. Partial sleep deprivation occurs when a person or a lab animal sleeps too little for several days or ...
In individuals deprived of sleep, somnolence may spontaneously dissipate for short periods of time; this phenomenon is the second wind, and results from the normal cycling of the circadian rhythm interfering with the processes the body carries out to prepare itself to rest. The word "somnolence" is derived from the Latin "somnus" meaning "sleep".
Sleep deprivation can be chronic or short-term depending on the severity of the patient's condition. Many patients report hallucinations because sleep deprivation impacts the brain. An MRI study conducted at Harvard Medical School in 2007 found that a sleep-deprived brain was not capable of being in control of its sensorimotor functions, [ 41 ...
EDS can be a symptom of a number of factors and disorders. Specialists in sleep medicine are trained to diagnose them. Some are: Insufficient quality or quantity of night time sleep [5] Obstructive sleep apnea [6] Misalignments of the body's circadian pacemaker with the environment (e.g., jet lag, shift work, or other circadian rhythm sleep ...
Local sleep is a neurological phenomenon where brain activity in an organism that is otherwise awake enters a state which closely resembles that of sleep. [1] [2] In an electroencephalogram, these patterns generally resemble NREM slow-wave sleep, and oscillate between 'on' and 'off' periods in the same way that would be expected during an actual sleeping state.
