Summary
Internet addiction tendency is linked to altered brain connectivity within the default-mode network (DMN). This DMN connectivity helps explain how excessive internet use impacts sleep quality.
Area of Science:
- Neuroscience
- Psychiatry
- Addiction Research
Background:
- Internet addiction (IA) is a growing concern, affecting health, emotion, and sleep.
- Previous research suggests a negative link between IA and sleep quality, but the neural mechanisms are unclear.
Purpose of the Study:
- To investigate the neural pathways connecting IA tendency and sleep quality using resting-state functional connectivity (RSFC).
Main Methods:
- Resting-state functional connectivity (RSFC) analysis was employed.
- Behavioral correlations and mediation analysis were conducted.
Main Results:
- A positive correlation was found between IA tendency and sleep quality.
- IA tendency positively correlated with functional connectivity strength in the default-mode network (DMN), specifically involving regions like the precuneus, middle temporal gyrus, anterior cingulate, superior frontal gyrus, and inferior parietal lobe.
- Mediation analysis confirmed that IA tendency mediates the relationship between DMN functional connectivity and sleep quality.
Conclusions:
- Intrinsic DMN connectivity plays a crucial role in the impact of IA tendency on sleep quality.
- These findings provide neural evidence for understanding the complex relationship between internet addiction and sleep disturbances.

01:13Insufficient Sleep and Sleep Deprivation
147
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.

01:11Understanding Sleep
234
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...

01:24Substance Use Disorders Affecting Sleep
173
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 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).

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.
