Technology provides many benefits to individuals and society but it is not without its down side. Sara Thomée, doctoral student, and colleagues at the University of Gothenburg’s Sahlgrenska Academy conducted four studies to evaluate the effects of heavy computer and cell phone by young adults on sleep quality, stress levels, and general mental health. The studies found that young adults who make particularly heavy use of mobile phones and computers run a greater risk of sleep disturbances, stress, and symptoms of mental health.
· Frequent computer use without breaks was found to increase the risk of stress, sleeping problems, and depressive symptoms in women
· Males who use mobile phones / computers extensively without breaks were more likely to develop sleeping problems.
· Regularly using a computer late at night was associated not only with sleep disorders but also with stress and depressive symptoms in both men and women
Adequate sleep is related to cognitive performance and is independently linked with longevity. The artificial light from TV and computer screens and smart phones affects melatonin production and throws off circadian rhythms, preventing deep, restorative sleep.
