Insufficient Sleep and Sleep Deprivation01:13

Insufficient Sleep and Sleep Deprivation

685
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.

Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

307
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.

Sleep-Wake Cycles

2.5K
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:

Nightmares and Night Terrors01:18

Nightmares and Night Terrors

304
Nightmares and night terrors represent two distinct types of sleep disturbances that differ in timing, characteristics, and the sleeper's recall of the event. Nightmares are vivid, disturbing dreams that usually awaken the sleeper from REM sleep, a stage of sleep where brain activity is high, and dreams are most frequent. Upon awakening, individuals often have detailed recollections of their nightmares, which can include themes of threats to survival, security, or self-esteem.

Management of Insomnia

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...

Insomnia01:27

Insomnia

298
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...

Area of Science:

  • Sleep science
  • Psychology
  • Public health

Background:

  • The COVID-19 pandemic caused widespread societal lifestyle changes.
  • Understanding the impact of such crises on sleep is crucial for public health.

Purpose of the Study:

  • To investigate the effect of the COVID-19 outbreak context on sleep quality and mood.
  • To assess changes in sleep parameters and emotional states during the pandemic.

Main Methods:

  • An online survey was administered to participants previously recruited for sleep questionnaire validation.
  • Participants completed the Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), Satisfaction, Alertness, Timing, Efficiency, and Duration (SATED) questionnaire, and Profile of Mood States (POMS).

Main Results:

  • A significant worsening of sleep quality (PSQI scores increased) was observed during the COVID-19 outbreak.
  • Participants reported an increase in negative mood (POMS scores increased).
  • Decreased sleep quality was substantially correlated with increased negative mood (p < 0.001).

Conclusions:

  • COVID-19 outbreak-related events are associated with diminished sleep quality and heightened negative mood.
  • The findings underscore the importance of sleep for health, particularly immune function.
  • Psychological support and awareness initiatives are recommended for individuals affected by such crises.
