Smartphones can make you hyperactive


c be the reason behind these attention-deficit/hyperactivity disorder (ADHD)-like symptoms, new research suggests.

Recent polls have shown that as many as 95 percent of smartphone users have used their phones during social gatherings; that seven in 10 people used their phones while working; and one in 10 admitted to checking their phones during sex. Smartphone owners spend nearly two hours per day using their phones, said lead researcher Kostadin Kushlev from University of Virginia in the US.

“We found the first experimental evidence that smartphone interruptions can cause greater inattention and hyperactivity – symptoms of attention deficit hyperactivity disorder – even in people drawn from a nonclinical population,” Kushlev said.

During the study, 221 students at University of British Columbia in Canada drawn from the general student population were assigned for one week to maximise phone interruptions by keeping notification alerts on, and their phones within easy reach.

During another week participants were assigned to minimise phone interruptions by keeping alerts off and their phones away.

At the end of each week, participants completed questionnaires assessing inattention and hyperactivity.
