|October 27, 2017
Summary
A workplace intervention improved sleep duration by 8 minutes per day and reduced sleep insufficiency among employees. This highlights the impact of workplace factors on sleep quality and quantity.
Area of Science:
- Occupational Health
- Sleep Science
- Organizational Psychology
Background:
- Work-family conflict negatively impacts employee well-being and sleep.
- Workplace interventions can address psychosocial factors affecting employees.
Purpose of the Study:
- To test if a workplace intervention improves sleep quantity and quality.
- To evaluate the impact of increased family-supportive supervision and employee control over work time on sleep.
Main Methods:
- Cluster-randomized trial at a global information technology firm.
- Intervention involved a 3-month social and organizational change process.
- Sleep was measured using actigraphy and self-reported surveys.
Main Results:
- Employees in the intervention group slept 8 minutes more per day (P < .05).
- Sleep insufficiency was significantly reduced in the intervention group (P = .002).
- Increased control over work hours mediated sleep improvements.
Conclusions:
- Workplace interventions can improve sleep duration and sufficiency, even without directly targeting sleep.
- Environmental and psychosocial workplace factors are crucial for addressing sleep deficiency.

01:13Insufficient Sleep and Sleep Deprivation
967
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.

01:19Management of Insomnia
690
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...

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.

Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which...

01:27Insomnia
508
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.

01:21Sleep Apnea
605
Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.
