Management of Insomnia01:19

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...

Insomnia

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.

The Influence of Cognition on Affect01:29

The Influence of Cognition on Affect

Cognition plays a pivotal role in shaping emotional experiences, as demonstrated by Schachter and Singer’s two-factor theory of emotion. According to this model, emotion arises from a combination of physiological arousal and cognitive interpretation. The body’s physiological response to stimuli is ambiguous and only gains emotional significance through cognitive labeling. For instance, an increased heart rate and adrenaline surge while standing near an attractive person may be interpreted as...
The Influence of Affect on Cognition01:29

The Influence of Affect on Cognition

Positive affect significantly influences cognitive processes, including evaluation, memory, creativity, and social judgments. Compared to negative affect, positive emotional states promote more favorable interpretations of stimuli, cognitive flexibility, and heuristic processing. These effects highlight emotions' powerful role in shaping how individuals perceive, remember, and interact with the world.Influence on Evaluation and AttributionWhen individuals experience positive affect, they are...
Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

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,...
Sedatives and Hypnotics: Overview01:23

Sedatives and Hypnotics: Overview

Sedatives are drugs that alleviate anxiety, while hypnotics induce sleep. Both classes of medication suppress neuronal activity, leading to a calming effect for sedatives and facilitating sleep for hypnotics.
Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve in...

Area of Science:

  • Sleep science
  • Cognitive psychology
  • Affective science

Background:

  • Insomnia is a widespread and disabling chronic disorder.
  • Cognitive control issues like worry and rumination are linked to sleep disturbance.
  • Affective control, or regulating emotions, is a newly investigated factor in sleep problems.

Purpose of the Study:

  • To review cognitive control's role in sleep disturbance.
  • To explore affect control's impact on sleep.
  • To examine sleep disturbance's effect on affect control.
  • To integrate cognitive and affective science for insomnia understanding and treatment.

Main Methods:

  • Literature review of cognitive control and sleep.
  • Literature review of affect control and sleep.
  • Review of studies on sleep's impact on affect.
  • Synthesis of repetitive-thought and affective science for insomnia.

Main Results:

  • Evidence suggests dysfunctional cognitive control (e.g., thought suppression, worry) is associated with sleep disturbance.
  • Emerging research indicates dysfunctional affect control (managing positive/negative emotions) also contributes to sleep disturbance.
  • Sleep disturbance can negatively impact next-day emotional regulation.
  • Combining insights from cognitive and affective science offers a promising path for insomnia research and intervention.

Conclusions:

  • Dysfunctional cognitive and affect control mechanisms are significantly implicated in insomnia.
  • Sleep disturbance itself can exacerbate problems with emotional regulation.
  • An integrated approach merging cognitive and affective science is crucial for advancing insomnia understanding and developing effective interventions.
