Intensive mobile phone use triggers sleep disorder and depression

Young adults who are constantly connected to the Internet via their mobile phone or computer are more likely to suffer from sleep disturbances, stress and symptoms of mental health, according to a study. "Public health advice should therefore include information on the healthy use of this technology," researcher Sara Thomee from the Sahlgrenska Academy at the University of Gothenburg, Sweden, said. Doctoral student Thomee and her research colleagues at the University of Gothenburg's Sahlgrenska Academy have conducted four different studies looking at how the use of computers and mobile phones affects the mental health of young adults. These studies, which included questionnaires for 4,100 people aged 20-24 and interviews with 32 young heavy ICT users, reveal that intensive use of mobile phones and computers can be linked to stress, sleep disorders and depressive symptoms. "We looked at the effects both quantitatively and qualitatively and followed up the volunteers a year on," Thomee explained. "The conclusion is that intensive use of ICT can have an impact on mental health among young adults," she said. The studies reveal, for example, that heavy mobile use is linked to an increase in sleeping problems in men and an increase in depressive symptoms in both men and women. "Those who find the constant accessibility via mobile phones to be stressful are most likely to report mental symptoms," Thomee said. Frequently using a computer without breaks also increases the risk of stress, sleeping problems and depressive symptoms in women, whereas men who use computers intensively are more likely to develop sleeping problems. "Regularly using a computer late at night is associated not only with sleep disorders but also with stress and depressive symptoms in both men and women," she said. A combination of both heavy computer use and heavy mobile use makes the association even stronger. One conclusion is that public health advice to young people should include information on how to use ICT in a healthy way: "This means taking breaks, taking time to recover after intensive use, and putting limits on your availability," she added.
