Insufficient Sleep and Sleep Deprivation01:13

Insufficient Sleep and Sleep Deprivation

538
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...

Sleep-Wake Cycles01:24

Sleep-Wake Cycles

2.2K
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:

Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

273
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.

Insomnia01:27

Insomnia

239
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.

Anxiety: Overview01:18

Anxiety: Overview

527
Anxiety is a common mental disorder featuring excessive worry, fear, and apprehension, significantly affecting daily life. People with anxiety disorders experience persistent and intense anxiety, interrupting their everyday functioning.
Individuals with anxiety often experience a range of physical and emotional symptoms, including sweating, trembling, tachycardia, and disturbances in sleep patterns. These symptoms vary in intensity and frequency but are generally disruptive and distressing.

Nightmares and Night Terrors01:18

Nightmares and Night Terrors

243
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.

Area of Science:

  • Psychology
  • Academic Performance
  • Student Health

Background:

  • Test anxiety is a biopsychosocial process impacting academic performance.
  • This study examines the Sleep Anxiety Performance Process (SAPP) model.

Purpose of the Study:

  • To test the SAPP model in undergraduate psychology statistics students.
  • To investigate the relationship between sleep, anxiety, and academic performance.

Main Methods:

  • A passive observational study involving 167 undergraduates.
  • Data collected 2 days before a midterm exam using electronic measures and Sleep Mood Study Diaries (SMS).

Main Results:

  • A reciprocal relationship was found between sleep quality/restfulness (Q&R) and test anxiety.
  • Test anxiety, prior exam performance, non-native English speaker status, and motivation predicted exam performance.

Conclusions:

  • Data support the SAPP model: sleep and anxiety interact reciprocally, impairing academic performance.
  • Findings have implications for student health beyond academic outcomes.
