Smartphone overuse linked to anxiety and depression, especially in women
A large-scale study by the University of Toronto has revealed a clear link between excessive smartphone use and mood disorders like anxiety and depression. The research, involving over 50,000 participants, also found that women report higher levels of problematic usage than men, with societal expectations playing a key role in their habits.
The study, the largest of its kind, highlighted how women tend to use smartphones more for messaging and social media. Researchers suggested that cultural norms—such as the expectation for women to remain accessible for emotional support—may drive this behaviour. One east-end Toronto consultant admitted using her phone to escape unhappy thoughts during the day and to ward off nightmares at night, often playing Design Home to distract herself.
Experts warn that keeping smartphones in the bedroom disrupts deep sleep, as notifications and the brain’s awareness of incoming alerts prevent proper rest. The study also introduced the 'adult pacifier' theory, proposing that many, especially women, turn to their phones as a way to avoid stress or negative emotions. In response, researchers launched Healthy Screens, a resource offering practical advice. Recommendations include removing phones from the bedroom, setting screens to grayscale, and cutting down on notifications. The findings stress that solutions must be tailored to different groups, considering factors like gender, age, and location.
The study confirms that problematic smartphone use is tied to mental health struggles, particularly among women. With tailored strategies now available through Healthy Screens, individuals can take steps to reduce dependency. The research underscores the need for targeted interventions to help people manage their digital habits more effectively.
