Summary
Digital technology addiction is a growing global problem, significantly worsening sleep quality and causing daytime dysfunction. This addiction impacts brain chemistry and behavior, leading to severe sleep loss and other health issues.
Area of Science:
- Neuroscience
- Psychiatry
- Public Health
Background:
- The World Health Organization recognizes digital technology addiction as a global issue, exacerbated by the COVID-19 pandemic.
- Excessive screen time disrupts daily functioning and sleep patterns, with ongoing research into contributing factors like blue-light exposure and lifestyle variables.
- Understanding the mechanisms behind digital addiction is crucial, especially for adolescents, in the context of increasing digital engagement.
Purpose of the Study:
- To provide a narrative overview of recent literature on digital technology addiction and its impact on sleep.
- To establish a conceptual framework for understanding digital addiction as a primary driver of sleep deficits in the digital age.
- To discuss definitions and mechanistic models of digital addiction.
Main Methods:
- A narrative review of recent scientific literature on digital technology addiction and sleep.
- Analysis of conceptual and mechanistic models of addiction.
- Examination of the neurobiological and behavioral correlates of digital addiction.
Main Results:
- Digital addiction is characterized by compulsive device use, leading to severe sleep loss, emotional distress, and cognitive impairment.
- The syndrome affects neurotransmitter systems (GABAergic, glutamatergic) and alters synaptic plasticity in dopamine and serotonin pathways.
- Behavioral symptoms include eating disorders, social withdrawal, and potential links to dysfunctional melatonin and vitamin D metabolism.
Conclusions:
- Digital addiction is a significant public health concern with profound impacts on sleep and overall well-being.
- Sleep deficit is a key factor in the holistic understanding of digital addiction.
- Further research into metabolic pathways and the development of holistic treatment strategies is warranted.

01:13Insufficient Sleep and Sleep Deprivation
224
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.

01:24Substance Use Disorders Affecting Sleep
225
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.

Sleep, an essential biological state, involves significant reductions in physical activity, sensory awareness, and interaction with the environment. This complex physiological process is primarily regulated by specific brain regions, notably the hypothalamus and pons, which govern the sleep-wake cycle or circadian rhythm.
The circadian rhythm, a nearly 24-hour cycle, is deeply influenced by environmental light cues. Light exposure directly affects the hypothalamus, which in turn regulates...

134
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.

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).

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...
