ABSTRACT
In the digital age, mobile phones have particularly become an essential part of everyday life, mainly among young adults. However, excessive dependence on these devices has raised concerns regarding their impact on sleep quality and overall well-being. This research aims to investigate the connection between mobile phone dependence and sleep disorders among young adults, with a special focus on its implications for mental health. The study investigates how prolonged screen time, nighttime mobile usage, and digital distractions contribute to disrupted sleep patterns, insomnia, and poor sleep hygiene. Additionally, it examines the correlation between sleep disturbances and mental health issues such as anxiety, stress, and depression. Using a quantitative approach, data will be gathered via organized surveys conducted to a sample of young adults aged 18 to 25. The findings of this research are expected to offer insights into the psychological and physiological consequences of mobile phone overuse and highlight the need for awareness and behavioral interventions to promote healthier digital habits and improve mental well-being.
1. INTRODUCTION
Mobile phones play a crucial role in everyday life., especially for young adults. While they offer convenience, excessive use—particularly at night—affects sleep quality, leading to fatigue, stress, and reduced focus. Additionally, prolonged phone use decreases physical activity, impacting overall well-being. This study explores the link between mobile dependence, sleep disorders, and mental health, aiming to promote healthier digital habits.
1.2. STATEMENT OF THE PROBLEM
The increasing utilization of mobile phones by young adults is becoming more dynamic and is emerging into most aspects of life. The popularity of using these devices before bedtime has expressed worries regarding the potential impact on sleep effectiveness and overall psychological well-being. Low-quality sleep can lead to psychological health problems. Mobile phone dependence can lead to a significant concern for public health, involving both positive and negative effects. While mobile phones offer convenience and the ability to various services, overuse can result in dependence and sleep problems. Studies show that inappropriate mobile phone use is affected. Therefore, a study on this relationship can offer significant and worthwhile insights for creating effective strategies to mitigate the negative impacts of mobile phone dependence on sleep and overall well-being in young adults.
- How dependent are young adults on their mobile phones?
- How does mobile phone use affect sleep quality and duration?
- Is there a link between mobile dependence and reduced physical activity?
- What strategies can help reduce mobile dependence and improve well-being?
1.3 OBJECTIVES OF THE STUDY
The main goals of this study are:
- To study the extent of mobile phone dependence among young adults.
- To assess the impact of mobile phone use on sleep quality and duration.
- To study the correlation between mobile dependence and reduced physical activity.
- Examine the Interconnected Connection Between Sleep Disorders and Mental Health.
1.4 SIGNIFICANCE OF THE STUDY
This study is important because it will assist young adults in recognizing how the overuse of mobile phones impacts their sleep and health. It will also offer valuable perspectives for:
Students and Young Professionals: To encourage better phone usage habits for improved sleep and productivity.

The replies to the survey suggest that people recognize various strategies to mitigate mobile phone dependence and improve sleep quality. Common suggestions include setting screen time limits, using blue light filters, avoiding phone use before bedtime, engaging in offline activities such as reading or meditation, and keeping phones away from the bed. Some respondents also emphasized the importance of maintaining a consistent sleep schedule and using apps to monitor and limit screen time. These answers indicate that individuals are aware of the unfavorable effects of excessive phone use on sleep and overall well-being. However, while awareness is present, successfully implementing these strategies may be challenging due to habitual phone use and digital dependence. Encouraging self-discipline, promoting digital detox routines, and fostering mindfulness-based practices could help individuals adopt healthier screen habits and improve their sleep quality.
4. SUMMARY: _
The survey highlights a strong link between mobile phone usage, sleep disturbances, and mental health among young adults. Key findings include:
4.1 High Screen Time & Digital Dependence: Many respondents use their phones for over 4-6 hours daily, impacting focus, productivity, and real-life interactions. Compulsive phone checking suggests signs of digital addiction and increased anxiety.
4.2 Emotional & Mental Health Impact: Over 84.9% use phones as a coping mechanism for stress, boredom, or negative emotions. Excessive reliance on digital distractions may contribute to heightened stress, emotional detachment, and an increased risk of anxiety or depression.
4.3 Physical Discomfort & Sedentary Lifestyle: Prolonged phone use causes eye strain, headaches, and muscle stiffness, while 75.3% report reduced physical activity, increasing risks of chronic health issues and fatigue.
4.4 Sleep Disruptions & Fatigue: More than 72% experience sleep disturbances, with 52.7% struggling to fall asleep and 74.2% waking up tired, affecting cognitive function, mood stability, and daily performance.
4.5 Guilt & Behavioural Challenges: While many feel guilty about excessive phone use, changing habits remains difficult, highlighting the need for structured interventions like screen time limits, mindfulness practices, and digital detox strategies to support better mental and physical well-being.
5. SUGGESTIONS:
Young adults who use their phones excessively report experiencing sleep disturbances, decreased physical activity, and a deterioration in their mental health. To address these challenges, it is recommended to establish digital boundaries, prioritize mental health, improve sleep hygiene, increase awareness through digital literacy, encourage healthy coping mechanisms, promote physical activity, and support mental health services. Establishing digital boundaries, implementing "no-phone" zones, and scheduling phone-free periods can help reduce dependency and improve focus. Instead of screen time, encourage mental wellness activities, offline hobbies, and social support systems. Establishing a consistent sleep schedule and avoiding phone use before bedtime can help manage stress better. Educating youth about the psychological and physiological impact of screen addiction and encouraging healthy coping mechanisms can help reduce reliance on phones. Supporting mental health services and promoting a balanced digital lifestyle can help individuals regain control over their time and mind, ultimately improving productivity, happiness, and overall quality of life.
6. CONCLUSION
The findings highlight the significant impact of mobile phone use on sleep, physical health, and mental well-being among young adults. Late-night screen exposure, disrupted sleep, and reduced physical activity contribute to fatigue, anxiety, and stress.
To mitigate these effects, individuals should:
- Set screen-time limits to reduce digital dependency and improve focus.
- Use blue light filters & phone-free bedtime routines for better sleep.
- Engage in physical activity to counteract sedentary habits and boost energy.
- Practice digital detoxes by prioritizing real-world interactions.
- Adopt healthier coping mechanisms like meditation, journaling, or hobbies to manage stress.
By fostering mindful technology use, young adults can enhance sleep quality, mental health, productivity, and overall well-being.
