Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

394
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,...

Management of Insomnia

518
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...

REM Sleep Behavior Disorder01:15

REM Sleep Behavior Disorder

1.3K
REM Sleep Behavior Disorder (RBD) is a sleep disorder characterized by the absence of muscle paralysis that normally occurs during the REM phase of sleep. This absence allows individuals to physically act out their dreams, which are often vivid and disturbing. Common behaviors exhibited during episodes include kicking, punching, and yelling. These actions can be dangerous, potentially leading to injuries for the person with RBD or their bed partner.
RBD is significantly associated with...

Blind Procedures

Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which...

Sleepwalking and Sleep Talking01:17

Sleepwalking and Sleep Talking

831
Somnambulism, commonly known as sleepwalking, involves individuals engaging in activities ranging from simple walking to more complex behaviors such as driving. Sleepwalking typically occurs during the slow-wave sleep stages 3 and 4 early in the night when the person is not dreaming, contradicting the myth that sleepwalkers are acting out their dreams.
Factors that increase the likelihood of sleepwalking include sleep deprivation and alcohol consumption. Contrary to common beliefs, it is safe...

Insufficient Sleep and Sleep Deprivation01:13

Insufficient Sleep and Sleep Deprivation

820
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...

Area of Science:

  • Adolescent sleep medicine
  • Digital health interventions
  • Behavioral sleep therapy

Background:

  • Adolescents globally experience insufficient sleep duration, often due to early school start times.
  • Current interventions to advance sleep timing are limited in their disseminability.
  • This study piloted a digital behavioral intervention to address adolescent sleep timing and mood.

Purpose of the Study:

  • To evaluate the feasibility and preliminary efficacy of a digital behavioral intervention for improving adolescent sleep timing.
  • To assess the impact of the intervention on sleep duration, sleep latency, and self-reported sleep quality.
  • To explore potential effects on mood and emotion regulation in adolescents.

Main Methods:

  • Fourteen healthy adolescents aiming for earlier sleep times participated over 10 weeks.
  • A two-week baseline was followed by an eight-week intervention combining digital CBT-I, values clarification, and motivational interviewing.
  • Participants were randomized to active or placebo light therapy, with both groups receiving the digital intervention for the first four weeks.

Main Results:

  • Both groups showed significant improvements in going to sleep earlier and sleeping longer compared to baseline.
  • Self-reported sleep quality improved, supporting objective sleep log findings.
  • No significant changes were observed in depressive symptoms or emotion regulation.

Conclusions:

  • The digital behavioral intervention shows potential for improving adolescent sleep duration and quality.
  • Further research with larger sample sizes is warranted to confirm efficacy and long-term outcomes.
  • The intervention's components, including CBT-I elements, appear beneficial for adolescent sleep behavior.
