Summary
Critical illness and Intensive Care Unit (ICU) stays disrupt sleep, worsening patient outcomes. Recent guidelines and the COVID-19 pandemic highlight the need to understand and improve sleep for critically ill patients.
Area of Science:
- Critical care medicine
- Sleep science
- Epidemiology
Background:
- Intensive Care Unit (ICU) stays significantly impact patient sleep.
- Sleep disturbances are prevalent in critically ill patients and linked to adverse outcomes.
- The COVID-19 pandemic exacerbated sleep disruption in ICUs.
Purpose of the Study:
- To review current literature on sleep disturbances in critically ill patients.
- To discuss the impact of critical illness on sleep patterns.
- To explore evolving understanding and future research directions.
Main Methods:
- Systematic literature review of studies on sleep and critical illness.
- Analysis of clinical practice guidelines.
- Synthesis of research findings, including pandemic-related impacts.
Main Results:
- Poor sleep is a common complication in critical illness.
- Sleep disruption can persist post-ICU admission.
- Sleep disturbances are associated with increased morbidity and mortality.
Conclusions:
- Improved focus on sleep and circadian rhythm is crucial in critical care.
- Further research is needed to develop effective interventions for sleep disruption.
- Addressing sleep complications is vital for improving patient recovery and survival.

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).

01:13Insufficient Sleep and Sleep Deprivation
149
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.

262
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...

01:24Substance Use Disorders Affecting Sleep
176
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.

01:15REM Sleep Behavior Disorder
213
REM Sleep Behavior Disorder (RBD) is a sleep disorder characterized by the absence of muscle paralysis that normally occurs during the REM phase of sleep. This absence allows individuals to physically act out their dreams, which are often vivid and disturbing. Common behaviors exhibited during episodes include kicking, punching, and yelling. These actions can be dangerous, potentially leading to injuries for the person with RBD or their bed partner.

01:11Understanding Sleep
252
Sleep, an essential biological state, involves significant reductions in physical activity, sensory awareness, and interaction with the environment. This complex physiological process is primarily regulated by specific brain regions, notably the hypothalamus and pons, which govern the sleep-wake cycle or circadian rhythm.
The circadian rhythm, a nearly 24-hour cycle, is deeply influenced by environmental light cues. Light exposure directly affects the hypothalamus, which in turn regulates...
