By A friend of mine teaches high school English. She’s been doing it for fourteen years. She told me recently that the kids sitting in her classroom now are fundamentally different from the ones she started with — not in intelligence, not in curiosity, not in the things that make teenagers teenagers. But in the background noise they’re carrying around.
“They’re tired in a way I didn’t see before,” she said. “Not sleepy. Just worn.”
That observation matches what the data has been showing for over a decade. Anxiety among teens and young adults has been rising steadily — not spiking dramatically in one moment, but climbing persistently across age groups, across demographics, across countries that are otherwise quite different from each other. Something real is happening. The argument worth having is about what, exactly.
The Numbers First
Rates of anxiety disorders among people under 25 have risen measurably since roughly the early 2010s. The pandemic accelerated an existing trend rather than creating a new one — which is an important distinction. This isn’t a COVID story, though COVID made it worse. It’s a longer structural story with multiple causes that converged.
Rates of depression and anxiety among adolescent girls have been particularly sharp and have drawn the most research attention. But the trend affects young men too, in somewhat different ways — more externalizing, more isolation, different patterns that get less media attention partly because they’re less legible as classic mental health symptoms.
The Social Media Question — What We Actually Know
The debate about social media’s role in the teen anxiety crisis has gotten politically charged in ways that make it harder to have the honest, specific conversation it deserves.
Here’s what the research actually shows: passive social media use — scrolling through feeds without engaging — is more consistently associated with worse mental health outcomes than active use. Social comparison, which platforms are specifically designed to facilitate, has measurable effects on self-worth and body image, particularly in adolescent girls. The before-bed use specifically affects sleep quality, and sleep deprivation is its own significant contributor to anxiety and depression.
Here’s what the research doesn’t cleanly show: that social media is the primary cause of rising anxiety, or that removing it would reverse the trend. The timeline correlation is real — smartphones became ubiquitous among teens around 2012, which is roughly when the mental health trends started moving. But correlation isn’t causation, and the full picture is considerably more complicated.
The Things That Get Less Attention
Academic pressure has intensified. The college admissions arms race has filtered down into middle school in ways that create chronic stress around performance and achievement at ages when brains are not built to handle it well. Kids who are anxious about a single bad grade in seventh grade because of what it might mean for their college prospects are not being irrational — they’re responding accurately to a system that has communicated that everything counts all the time.
Economic anxiety is absorbed from families. Kids growing up in households under financial stress absorb that stress, even when it isn’t discussed explicitly. The generation coming of age now grew up watching 2008, watching the pandemic, hearing constant conversation about costs and instability.
Climate anxiety is documented and real. A significant portion of young people report genuine distress about the climate future — not abstract concern, but personal fear about what their world will look like. Dismissing this as media-induced alarmism skips the part where it’s a reasonable response to real information about real risks.
Why This Matters
The rising anxiety figures aren’t just a mental health statistic. Anxiety affects school performance, social development, career trajectories, relationship patterns, and long-term health. A generation arriving at adulthood with high anxiety loads is a generation that needs structures — in healthcare, in workplaces, in communities — that we haven’t fully built yet.
What helps is also reasonably well established: access to mental health care (inadequate and undersupplied in most communities), stable adult relationships, sleep, physical activity, and environments that communicate safety and belonging. None of these is a revelation. The gap is between knowing what helps and actually providing it at scale.
