Insufficient Sleep and Sleep Deprivation01:13

Insufficient Sleep and Sleep Deprivation

567
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...

Understanding Sleep01:11

Understanding Sleep

1.1K
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...

Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

276
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

2.3K
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:

Correlations02:20

Correlations

35.1K
Correlation means that there is a relationship between two or more variables (such as ice cream consumption and crime), but this relationship does not necessarily imply cause and effect. When two variables are correlated, it simply means that as one variable changes, so does the other. We can measure correlation by calculating a statistic known as a correlation coefficient. A correlation coefficient is a number from -1 to +1 that indicates the strength and direction of the relationship between...

Sleep Apnea01:21

Sleep Apnea

304
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.
The condition is more prevalent among...

Area of Science:

  • Public Health
  • Sleep Medicine
  • Epidemiology

Background:

  • The COVID-19 pandemic has caused global health, mental, and emotional challenges.
  • Sleep disturbances are a common consequence of widespread health crises like pandemics.

Purpose of the Study:

  • To review existing literature on sleep issues during the COVID-19 pandemic.
  • To propose future national strategies for mitigating pandemic-related sleep problems.

Main Methods:

  • Extensive literature search across PubMed, Google Scholar, Epistemonikos, and PsycINFO.
  • Inclusion criteria: English articles published between January and April 2020.
  • Cross-citation searches and independent review by two researchers.

Main Results:

  • Sleep is affected in patients, healthcare workers, and the general population during the pandemic.
  • Limited subjective data and a lack of objective sleep criteria were found in existing literature.
  • Obstructive Sleep Apnea (OSA) is a frequent comorbidity in COVID-19 patients.

Conclusions:

  • Sleep disruption is a significant issue during the COVID-19 pandemic.
  • There is a need for standardized objective measures to assess sleep in COVID-19.
  • Developing national strategies to improve sleep health is crucial.
