Insufficient Sleep and Sleep Deprivation

Insufficient Sleep and Sleep Deprivation

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.

Nightmares and Night Terrors

Nightmares and Night Terrors

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.

Socioemotional Development during Infancy

Socioemotional Development during Infancy

Socio-emotional development in infancy is primarily shaped by early emotional responses and social connections, with temperament playing a central role. Temperament refers to the consistent patterns in an individual's emotional and behavioral responses, observable even in infancy. By examining temperament, researchers can better understand an infant's unique ways of interacting with the world, influencing subsequent personality and socio-emotional growth.
Primary Temperament Types

Insomnia

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.

Substance Use Disorders Affecting Sleep

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.

Attention-Deficit/Hyperactivity Disorder

Attention-Deficit/Hyperactivity Disorder

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

Area of Science:

Pediatric Health
Sleep Medicine
Child Psychology

Background:

Emotional problems like anxiety and low mood are common in children.
Sleep problems in children are frequently associated with emotional difficulties.

Purpose of the Study:

To examine the link between sleep duration and internalizing symptoms (anxiety, low mood) in children aged 5-12 years.
To determine if insufficient sleep, based on National Sleep Foundation (NSF) guidelines, correlates with internalizing symptoms in children.

Main Methods:

A cross-sectional study involving 796 children aged 5-12 years from primary care settings in Toronto, Canada.
Linear regression analysis was used to assess the association between parent-reported sleep duration and internalizing symptoms (Strengths and Difficulties Questionnaire).
Analyses controlled for covariates including age, sex, socioeconomic factors, and BMI, and were repeated for insufficient sleep status.

Main Results:

A significant inverse association was found between sleep duration and internalizing symptoms (B = -0.33, p=0.012).
14% of 5-year-olds and 6% of 6-12-year-olds experienced insufficient sleep.
A trend suggested a link between insufficient sleep and internalizing symptoms (B = 0.64, p=0.086).

Conclusions:

The association between insufficient sleep and internalizing symptoms in children warrants further investigation.
Children experiencing internalizing symptoms may benefit from sleep support interventions.
