“Social media is making adults more anxious and depressed.”
Moderate confidence. Large reviews find small, mixed and highly context-dependent associations. Much of the evidence is cross-sectional or self-reported, so direction of effect and individual causality remain uncertain.
Some patterns of social-media use are associated with anxiety or depressive symptoms, but average effects are usually small and do not show that social media uniformly causes these conditions in adults.
Platform, content, harassment, social comparison, sleep disruption, purpose of use and the user's existing mental health can matter more than total minutes. Social media can also provide connection and support.
Safety note: Online harassment, self-harm content, disordered-eating content and compulsive use can cause meaningful harm even when average study effects are small. Blocking and reporting are reasonable safety steps.
Talk to a healthcare professional if: Seek help if anxiety, depression, sleep loss or compulsive use is persistent or impairing. Use crisis or emergency services for suicidal thoughts, threats, stalking or immediate danger.
Population averages cannot tell you how a feed affects you. Pay attention to whether particular accounts or activities leave you connected, informed, distressed, compulsive or sleep-deprived.
Run a one-week experiment: mute distressing accounts, disable nonessential alerts and set a stop time before bed. Compare mood, sleep and functioning rather than assuming all use is harmful.
