What is an Experiment?

11.9K
An experiment is a planned activity carried out under controlled conditions. The purpose of an experiment is to investigate the relationship between two variables. When one variable causes change in another, we call the first variable the explanatory or independent variable. The affected variable is called the response or dependent variable. In a randomized experiment, the researcher manipulates values of the explanatory variable and measures the resulting changes in the response variable. The...

Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

205
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.

Management of Insomnia

303
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...

Insufficient Sleep and Sleep Deprivation01:13

Insufficient Sleep and Sleep Deprivation

192
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...

Insomnia01:27

Insomnia

115
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...

REM Sleep Behavior Disorder01:15

REM Sleep Behavior Disorder

331
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...

Area of Science:

  • Pediatric Sleep Medicine
  • Digital Health Interventions
  • Child Development

Background:

  • Sleep problems are prevalent in young children, impacting development and challenging parents.
  • Limited access to professional support for pediatric sleep issues necessitates innovative solutions.
  • Culturally and family-tailored interventions are lacking despite their importance in children's sleep.

Purpose of the Study:

  • To evaluate the effectiveness of the "Nenne Navi" smartphone app for improving sleep habits in young Japanese children.
  • To assess the association between app-guided sleep improvements and children's mental development.
  • To conduct community-based long-term trials for culturally tailored sleep interventions.

Main Methods:

  • Community-based recruitment of 87 Japanese caregivers with young children experiencing sleep problems.
  • Intervention group used the "Nenne Navi" app with tailored suggestions monthly for one year.
  • Control group received educational videos on sleep health literacy; both groups received videos.

Main Results:

  • The
  • Nenne Navi
  • app demonstrated high user continuity (92% completion rate).
  • Significant improvements observed in the app group: earlier wake-up times and reduced sleep onset latency.
  • App-driven sleep improvements correlated with enhanced social development in children, with sustained lifestyle changes reported post-intervention.

Conclusions:

  • The "Nenne Navi" app is a viable tool for improving sleep habits in young Japanese children with high community adherence.
  • Pediatric sleep interventions can positively influence children's social development.
  • Future research should explore app effectiveness in diverse regions and investigate neuroscientific impacts of sleep changes.
