PHILADELPHIA — Spending all your time on "social media" sites like Facebook and IG turns out isn't the greatest thing for your mood.<br />A new study published in December's Journal of Social and Clinical Psychology has found a causal link between the time wasted on social media and depression and loneliness. <br />According to University of Pennsylvania researchers, people who cut back on social media show improvements in their mood and how they feel about life. <br />The U Penn psychologists found that subjects were less depressed and didn't feel as lonely when they limited their social media usage. <br />According to Marketwatch, the study looked at 143 undergrads and tested their mood using seven different scales. <br /><br />Half the students continued using social media sites as normal, while the other half were restricted to 10 minutes per day each for Facebook, Instagram and Snapchat. <br />The study concluded that people who spent less time on social media saw "clinically significant" falls in depression and in loneliness. <br />So if you want to be happier, spend less time on social media and more time just being social.
