填空题. It's no secret that scrolling through endless images and announcements of engagements, vacations, new babies and job promotions can make you feel like you're not accomplishing anything. But it's pretty much impossible to log off forever and never look back on. 1 Here's the good news: There might be a sweet spot when it comes to the amount of time you spend on social media. Keep your use down to just 2 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 monitored the participants' social media use for a week cross three platforms—Facebook, 3 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, anxieties, 4 and depression. Next, the authors separated the students from groups and 5 conducted the experiment for three weeks. One group was told to keep using social media as usually; another group was tasked with limiting 6 social media use to 10 minutes per platform a day. Researchers then looked at why the students fared in the seven 7 categories after the experiment. When study volunteers cut down their social media use to 30 minutes per day total, they experienced a "significant improvement in well-being", exhibiting reduced loneliness and depression, the authors wrote. There are a few caveats with this study: The participants only used iPhones in the experiment. The study also only monitored students who used Instagram, Facebook and Snapchat, but it doesn't reflect experiences 8 with other social media platforms. All that aside, there is something to be said for limiting social media while still being realistic about the fact you're never going to ditch it 9 entirely. Research has shown that excessive Facebook use can contribute to increase depression and loneliness, and a 2014 study found that social 10 media use can create social comparison, which can lead to lower self-esteem.
