For their study, the researchers assigned the participants, who all came from different professional sectors, to four groups of roughly equal size. The smartphone group reduced their private smartphone use by one hour a day for one week. The sport group increased their daily physical activity by 30 minutes. The combination group did both, and the control group didn’t change their routine at all. All participants completed online questionnaires before these interventions, immediately afterwards and two weeks after the intervention period ended, providing information about their well-being, both with regard to work and mental health.
