A recent study by Aalto University researchers reveals that the most mental strain from digital devices comes from frequent short usage, rather than prolonged screen time.
Researchers at Aalto University have found that the mental strain associated with digital device usage is primarily caused by constant, fragmented interactions with devices rather than extended periods of screen time. This insight emerged from a longitudinal study that aimed to understand user fatigue when using digital technology.
The study indicates that frequent short engagements, such as repeatedly checking a phone and sending messages throughout the day, are more taxing than long stretches of screen use. According to doctoral researcher Henrik Lassila, while duration of device use does contribute to stress levels, it's the users who repeatedly return to their phones in brief instances who tend to feel the most overwhelmed.
The findings highlight a concerning link between fragmented device usage, particularly with mobile devices, and the onset of stress and negative emotions. The research suggests that heavy mobile usage, especially in the mornings, can lead to mental overload, which creates a vicious cycle of stress that may drive individuals to use their devices even more frequently in piecemeal fashion.
