Management of Insomnia01:19

Management of Insomnia

499
The sleep cycle, an integral part of human health, consists of several stages with distinct characteristics and functions. It begins with a transition from wakefulness to sleep, known as the light sleep phase, followed by the restorative deep sleep phase, essential for physical recovery and growth. The cycle concludes with the Rapid Eye Movement (REM) phase, characterized by high brain activity and vivid dreaming. Insomnia, a prevalent sleep disorder, involves difficulty falling asleep, staying...

Insufficient Sleep and Sleep Deprivation01:13

Insufficient Sleep and Sleep Deprivation

805
Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required. For example, consistently sleeping 6 hours when the body needs 7-9 hours can lead to cumulative effects on health and well-being.
Sleep deprivation is a more severe form of sleep loss...

Insomnia01:27

Insomnia

380
Insomnia is a prevalent sleep disorder characterized by difficulty falling asleep, frequent awakenings during the night, and waking up too early without being able to return to sleep. People with insomnia often experience these disruptions at least three nights a week for at least one month. Chronic insomnia, which lasts for at least three months, can lead to increased anxiety, which in turn can worsen sleep difficulties, creating a cycle of sleeplessness and stress.
Multiple factors contribute...

Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

366
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.
Understanding the concepts of physical dependence,...

Sleep-Wake Cycles01:24

Sleep-Wake Cycles

2.7K
Sleep is an essential physiological process vital to maintaining overall well-being. The reticular activating system (RAS), a network of neurons in the brainstem, regulates wakefulness and sleep. While it may seem passive, sleep consists of distinct cycles, each with its unique characteristics and functions. Two key sleep phases are non-rapid eye movement (NREM) and  rapid eye movement (REM).
NREM Sleep
NREM sleep comprises four progressive stages that seamlessly merge:

Sedatives and Hypnotics Drugs: Miscellaneous Agents01:17

Sedatives and Hypnotics Drugs: Miscellaneous Agents

477
Sedatives and hypnotics encompass a wide range of substances, each with its unique mechanism of action, uses, and potential adverse effects.
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...

Area of Science:

  • Sleep Science
  • Occupational Health
  • Behavioral Medicine

Background:

  • Shift work is associated with significant sleep disturbances, including insomnia and daytime sleepiness.
  • Standard treatments like Cognitive Behavioral Therapy for Insomnia (CBT-i) present challenges for shift workers due to rigid scheduling requirements.
  • There is a clear need for specialized, non-pharmacological sleep interventions tailored to the unique demands of shift work.

Purpose of the Study:

  • To synthesize existing non-pharmacological sleep interventions for shift workers.
  • To identify gaps and inform the development of a preventative, multicomponent sleep management program.
  • To explore the potential of digital CBT-i for scalable insomnia treatment in this population.

Main Methods:

  • An informal review was conducted, following Phase 1 of the Framework for the Development and Evaluation of Complex Interventions.
  • The review synthesized literature on various non-pharmacological strategies aimed at improving sleep in shift workers.

Main Results:

  • Interventions reviewed include CBT-i, shift schedule adjustments, light exposure control, sleep hygiene education, planned napping, caffeine use, and mind-body practices.
  • Factors such as family roles, commuting, and eating behaviors were identified as overlooked aspects in current interventions.
  • Digital CBT-i platforms show promise as an accessible and cost-effective solution.

Conclusions:

  • Existing interventions offer a range of strategies, but a comprehensive, multicomponent approach is needed.
  • Future interventions should consider broader lifestyle factors impacting shift workers' sleep.
  • Digital CBT-i represents a scalable and potentially effective tool for managing insomnia in shift workers.
