A new study from the University of Duisburg-Essen in Germany suggests that compulsive internet use is closely linked to higher stress levels, poorer mood, and the neglect of everyday responsibilities. Researchers found that the strongest predictor of excessive internet use is not a person’s emotional state but the constant urge to go online.
Published in the journal PLOS One, the research followed nearly 900 adults over two weeks, tracking how internet habits affected their daily lives.
Study Tracked Daily Internet Habits
Researchers monitored participants who regularly used the internet for activities such as:
- Social media
- Online gaming
- Online shopping
- Adult content
For 14 consecutive days, participants recorded:
- Daily internet usage
- Stress levels
- Mood
- Urges to go online
Based on their responses, researchers classified participants into three groups:
- Non-problematic users
- At-risk users
- Pathological users
The findings revealed clear differences between these groups.
Stronger Urges Were Linked to Unhealthy Internet Use
Participants with the most severe patterns of internet use reported significantly higher stress levels and a more negative mood. They were also more likely to neglect important aspects of daily life, including:
- Physical exercise
- Face-to-face social interactions
- Other routine responsibilities
According to the researchers, the temptation to access the internet played a larger role in compulsive behavior than momentary emotions such as sadness or anxiety.
Why Compulsive Internet Use Becomes Difficult to Control
The study found that excessive internet use is reinforced through two key psychological mechanisms.
The first is the enjoyment people experience while using online platforms. The second is the relief from unpleasant emotions, such as stress, loneliness, or boredom.
Over time, this combination can create a cycle where individuals increasingly rely on the internet as a way to escape discomfort rather than simply for entertainment.
Researchers also emphasized that spending several hours online does not automatically indicate internet addiction.
Instead, problematic use develops when the urge to go online becomes difficult to resist and begins replacing essential daily activities.
While enjoyment remains a factor at every level of internet use, people with pathological usage patterns increasingly depend on online activities to cope with negative emotions.
Previous Research Found Brain Changes in Young People
The findings support earlier research published in PLOS Mental Health, which examined how internet addiction affects adolescent brain function.
The review analyzed data from 237 participants between the ages of 10 and 19 who had been formally diagnosed with internet addiction. The researchers combined evidence from 12 separate studies conducted between 2013 and 2023 by scientists at University College London (UCL).
The review identified changes in several brain networks responsible for:
- Executive control
- Memory
- Decision-making
- Attention
Researchers observed increased activity in certain brain regions during rest, alongside weaker communication between areas involved in self-control and cognitive function.
These neurological changes were also associated with reduced intellectual performance and poorer physical coordination in some adolescents.
Warning Signs of Problematic Internet Use
The research highlighted several behaviors commonly linked to compulsive internet use, including:
- Strong urges to use digital devices
- Excessive time spent consuming online content
- Hiding or lying about screen time
- Difficulty controlling internet use
Researchers noted that these behaviors may contribute to problems with impulse control, relationships, sleep quality, eating habits, and overall development in younger users.
Why Teenagers Face a Higher Risk
Adolescence is considered a particularly vulnerable stage because the brain continues to develop throughout the teenage years.
According to lead researcher Max Chang, understanding which brain regions are affected could help healthcare professionals develop more targeted treatments, including:
- Clinical interventions
- Cognitive and behavioral therapy
- Family-based therapy
The researchers also stressed the importance of educating parents to recognise the early warning signs of problematic internet use. Early intervention can help families establish healthier screen habits before compulsive behaviour begins affecting education, relationships, and overall well-being.
The findings suggest that compulsive internet use is driven less by how people feel in the moment and more by the persistent urge to stay connected. While spending long hours online is not necessarily unhealthy, internet use becomes problematic when it starts to replace important daily activities and becomes the primary way to cope with stress or emotional discomfort.
As internet use continues to grow across all age groups, researchers believe understanding these behavioural patterns will play an important role in developing effective prevention strategies and improving mental health support, particularly for young people.
