Its no secret that scrolling through endless images and announcements of engagements, vacations, new babies and job promotions can make you feel like youre not accomplishing anything. But its pretty much impossible to log off forever and never look back.

Heres the good news: There might be a sweet spot when it comes to the amount of time you spend on social media. Keeping your use down to just 30 minutes a day can lead to better mental health outcomes, according to research being published in December in the Journal of Social and Clinical Psychology.

Researchers from the University of Pennsylvania looked at social media use among 143 undergraduate students in two separate trials. One trial occurred in the spring and the other a few months later in the fall.

The study authors monitored the participants social media use for a week across three platforms Facebook , Instagram and Snapchat to get a baseline. Then researchers gauged the students mental health based on seven different factors: social support, fear of missing out, loneliness, self-acceptance, self-esteem, anxiety, and depression.

Next, the authors separated the students into groups and conducted the experiment for three weeks. One group was told to keep using social media as usual; another group was tasked with limiting social media use to 10 minutes per platform a day. Researchers then looked at how the students fared in the seven categories after the experiment.
