Caught in a Loop: Apparently, those videos in your feed of someone ranting about their spouse or petty friendship dramas may not be as random as they seem. In a new pilot study, researchers observed young adults’ brain activity as they watched videos pulled from their TikTok and Instagram accounts, then compared the results against each person’s score on a mood questionnaire. People with more depressive symptoms saw fewer positive relationship videos and more negative ones, and their brains responded differently to that personalized content. So researchers think social media feeds may be reflecting and reinforcing a negative outlook, rather than causing it.

How to Break Out of the Cycle: If you want to break the cycle, focus on how you_ _feel after scrolling. Then unfollow certain accounts that trigger you to replay recent arguments in your head or prompt you to begin doubting your relationships. Conversely, like or comment on videos that leave you feeling grounded or informed.

The Benefits: This kind of intentional engagement encourages your feed to show you content that lifts you up instead of bringing you down. Feeds don’t really transform overnight, but repeated signals will force change in the long term.
