Circadian Rhythm Sleep Disorders [PDF]

open access: yesPrimary Health Care Open Access, 2014
Though the theories on the reasons why humans need to sleep vary, there is no disagreement that sleep is essential to our wellbeing and survival. External and internal physiological parameters dictate our own individual body “clocks,” or circadian rhythms. Typically, this clock runs very close to a 24-hour cycle of sleep and wakefulness.

The Effect of Blindness on Biological Rhythms and the Consequences of Circadian Rhythm Disorder

open access: yesTürk Oftalmoloji Dergisi, 2023
Various physiological systems and behaviors such as the sleep-wake cycle, vigilance, body temperature, and the secretion of certain hormones are governed by a 24-hour cycle called the circadian system.

Genetic basis of human circadian rhythm disorders. [PDF]

open access: yes, 2013
Circadian rhythm disorders constitute a group of phenotypes that usually present as altered sleep-wake schedules. Until a human genetics approach was applied to investigate these traits, the genetic components regulating human circadian rhythm and sleep ...

Melatonin-related dysfunction in chronic restraint stress triggers sleep disorders in mice

open access: yesFrontiers in Pharmacology, 2023
Stress may trigger sleep disorders and are also risk factors for depression. The study explored the melatonin-related mechanisms of stress-associated sleep disorders on a mouse model of chronic stress by exploring the alteration in sleep architecture ...

Solving the mystery of human sleep schedules one mutation at a time. [PDF]

open access: yes, 2013
Sleep behavior remains one of the most enigmatic areas of life. The unanswered questions range from "why do we sleep?" to "how we can improve sleep in today's society?" Identification of mutations responsible for altered circadian regulation of human ...
