New research has found cellphone use by college students not only lowers their grades, but also boosts their anxiety, Newsmax Health reports.  

The findings are based on a survey of more than 500 students by Kent State University researchers. Daily cellphone use was recorded along with clinical measures of anxiety and each student's level of satisfaction in life. Participants also allowed the researchers to access their official university records in order to retrieve their actual, cumulative college grade point average (GPA).

The results showed that students who used their cellphones a lot had lower GPAs and higher levels of anxiety — and reported lower general happiness in their lives — than those who used their mobile devices less frequently.
