Sleep deprivation
Treating insomnia

Sleep deprivation can be implemented for a short period of time in the treatment of insomnia. Some common sleep disorders have been shown to respond to cognitive behavioral therapy for insomnia. Cognitive behavioral therapy for insomnia is a multicomponent process that is composed of stimulus control therapy, sleep restriction therapy (SRT), and sleep hygiene therapy. One of the components is a controlled regime of "sleep restriction" in order to restore the homeostatic drive to sleep and encourage normal "sleep efficiency". Stimulus control therapy is intended to limit behaviors intended to condition the body to sleep while in bed. The main goal of stimulus control and sleep restriction therapy is to create an association between bed and sleep. Although sleep restriction therapy shows efficacy when applied as an element of cognitive-behavioral therapy, its efficacy is yet to be proven when used alone. Sleep hygiene therapy is intended to help patients develop and maintain good sleeping habits. Sleep hygiene therapy is not helpful, however, when used as a monotherapy without the pairing of stimulus control therapy and sleep restriction therapy. Light stimulation affects the supraoptic nucleus of the hypothalamus, controlling circadian rhythm and inhibiting the secretion of melatonin from the pineal gland. Light therapy can improve sleep quality, improve sleep efficiency, and extend sleep duration by helping to establish and consolidate regular sleep-wake cycles. Light therapy is a natural, simple, low-cost treatment that does not lead to residual effects or tolerance. Adverse reactions include headaches, eye fatigue, and even mania.
