The cognitive shuffle is based on Beaudoin’s somnolent information processing theory. [5] [13] The somnolent information processing theory postulates the existence of a sleep onset control system that evolved to ensure that falling asleep tends to happen when it is evolutionarily opportune (safe, timely) to fall asleep.

Sleep is a state of reduced mental and physical activity in which consciousness is altered and certain sensory activity is inhibited. During sleep, there is a marked decrease in muscle activity and interactions with the surrounding environment.
Electroencephalography has been used for meditation research.. The psychological and physiological effects of meditation have been studied. In recent years, studies of meditation have increasingly involved the use of modern instruments, such as functional magnetic resonance imaging and electroencephalography, which are able to observe brain physiology and neural activity in living subjects ...

In another study, results of questionnaires measuring impairment through the psychomotor vigilance task (PVT) and the Epworth sleepiness scale (ESS) were stabilized at a normal level at 3-months follow-up. [10] Restricting sleep has also been shown to be an effective but usually temporary measure for treating depression. [11]

Relaxation may help reduce insomnia in those who have sleeping disorders. Those with insomnia may even give up sleeping aids just by practicing relaxation techniques ...
Young woman asleep over study materials. The relationship between sleep and memory has been studied since at least the early 19th century.Memory, the cognitive process of storing and retrieving past experiences, learning and recognition, [1] is a product of brain plasticity, the structural changes within synapses that create associations between stimuli.
