Insufficient Sleep and Sleep Deprivation01:13

Insufficient Sleep and Sleep Deprivation

138
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...

Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

163
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

1.2K
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:

Understanding Sleep01:11

Understanding Sleep

224
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...

Traits, Mood, and Subjective Wellbeing01:22

Traits, Mood, and Subjective Wellbeing

68
Subjective well-being (SWB) refers to an individual's self-evaluation of their overall life satisfaction, happiness, and fulfillment. This multifaceted construct is typically assessed by analyzing the balance of positive and negative emotions alongside perceptions of life satisfaction. Personality traits such as neuroticism and extraversion are strongly associated with variations in SWB, offering critical insights into the underlying mechanisms of emotional well-being.
Neuroticism and...

Insomnia01:27

Insomnia

81
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...

Summary

Work schedule impacts wellbeing through sleep duration, with work hours moderating this effect. Fewer work hours worsen the impact of sleepiness on wellbeing for shift workers.

Area of Science:

  • Occupational Health
  • Sleep Science
  • Psychology

Background:

  • Work schedules significantly influence employee wellbeing.
  • Understanding the interplay between work hours, sleep, and wellbeing is crucial for occupational health.
  • Shift work and long work hours are associated with adverse health outcomes.

Purpose of the Study:

  • To investigate the mediating role of sleep duration in the relationship between work schedules and wellbeing.
  • To examine the moderating effect of work hours on the link between work schedule and sleep.
  • To test a mediation-moderation hypothesis regarding work schedules, sleep, and wellbeing.

Main Methods:

  • Random phone interviews with 1,162 participants.
  • Identification of 172 day workers and 130 shift workers (≥35 hours/week).
  • Statistical analysis using mediation-moderation models.

Main Results:

  • Work schedule indirectly affected wellbeing via sleep duration (β=0.0511).
  • Shift work was negatively associated with sleep duration (β=-0.35, p<0.01).
  • Shorter sleep duration increased the impact of sleepiness on wellbeing (β=-0.15, p<0.02).
  • Work hours moderated the work schedule-sleep duration link; fewer hours amplified negative impacts.

Conclusions:

  • The findings support the proposed mediation-moderation hypothesis.
  • Sleep duration and work hours are critical factors in designing effective work schedules.
  • Optimizing work hours and ensuring adequate sleep are essential for mitigating negative wellbeing impacts.
