the link between instagram, tiktok and your daughter's school anxiety

This is not a post about taking the phone away.

It's also not a post that's going to tell you social media is fine and everyone needs to relax. The research is more nuanced than either of those positions, and your daughter deserves a more nuanced read than either of them too.

What this post is actually about is the specific mechanisms — the three things social media does that are particularly likely to interact badly with school anxiety in girls. Because understanding the mechanism is more useful than understanding the headline, and the headlines on this topic have not always been the most helpful.

first, a few numbers worth knowing

Around six in ten teenage girls use both TikTok and Instagram, according to Pew Research data from late 2024. 34% of teen girls say social media platforms make them feel worse about their own lives, compared with 20% of boys. That gap — between girls and boys — is not small, and it's consistent across multiple studies.

Teen girls are more likely than teen boys to report that social media negatively affects their sleep, productivity, self-confidence, and mental health overall. And girls, in particular, report feeling more pressure to post, to appear attractive or popular, and to engage with content that often triggers comparison or self-doubt.

None of this proves that Instagram caused your daughter's school avoidance. The relationship between social media and anxiety is complicated and the research is careful to say so. But for a girl who is already anxious, already struggling with how she fits in, already finding school a difficult place to be — the platforms are adding something to that picture. The question is what, specifically.

mechanism one: social comparison

This is the most well-documented of the three. Research from the UK ranked Instagram as the worst platform for young people's mental health, primarily due to its focus on appearance and lifestyle comparisons.

The comparison trap is not new — teenage girls have always compared themselves to each other, to images in magazines, to the version of their peers they encounter in corridors and cafeterias. What's changed is the scale, the frequency, and the fact that the comparison now happens in their bedroom at midnight, without a teacher or parent in the room.

The content she's seeing has been selected by an algorithm for maximum engagement, which means it tends toward the aspirational, the beautiful, the seemingly effortless. About 60% of health videos created by non-medical influencers contain misinformation. The version of teenage life that exists on Instagram is not representative of teenage life. But it is the version your daughter is measuring herself against, repeatedly, in moments that were previously just quiet.

For a child who is already anxious about how she appears to others — which is one of the core features of the social anxiety that underlies much school avoidance — this is not a neutral input.

mechanism two: the always-on social environment

School avoidance frequently involves significant anxiety about social evaluation. The fear of being watched, judged, found lacking. For many girls it's not the academic content of school that is unbearable — it's the social environment, the corridors, the group dynamics, the sense of being assessed constantly.

Social media extends that environment into every hour of the day.

Before smartphones, a child who found school socially overwhelming could come home and have some genuine relief from it. The social dynamics of school existed at school. Now they continue via DMs, group chats, story views, who has posted what and who has responded to whom. Social media creates what psychologists call "ambient anxiety" — a constant low-level stress from being perpetually connected and available. Teens describe feeling like they can't fully relax because someone might be trying to reach them, or they might miss something important.

For a child who is school avoidant partly because the social landscape of school feels unmanageable, there is no off switch. The social landscape follows her home.

mechanism three: sleep disruption

This one is less discussed in the context of school avoidance specifically, but it matters more than it tends to get credit for.

Anxiety is significantly worsened by poor sleep. The nervous system regulation that allows a child to manage difficult emotions and tolerate uncomfortable situations requires adequate sleep to function. A child who is getting six hours because she was on her phone until 1am is operating with a materially compromised capacity to cope — before the school morning has even started.

The blue light from screens suppresses melatonin production, making it harder to fall asleep. Nearly one-third of adolescents are using screens until midnight or later, directly impacting both sleep quality and emotional wellbeing.

This is not about moral panic over screen time. It's about a child who needs her nervous system to be as regulated as possible in order to get through a difficult morning, and who is systematically undermining that regulation every night. The phone in the bedroom at midnight is not a neutral variable in the school avoidance equation.

what the research does not say

It does not say that social media caused your daughter's school avoidance. Anxiety is multifactorial, school avoidance is multifactorial, and removing every device tomorrow would not resolve the underlying mechanisms that are making school difficult.

The association between social media use and mental health is highly complicated and multifaceted. There are genuine positive effects too — about half of teens still say social media makes them feel they have people who can support them through tough times, and for an isolated teenager those connections can matter.

What the research does say is that for girls in particular, and for anxious children specifically, the platforms are adding load to a system that is already under strain. Not as a cause. As a compounding factor.

so what do you actually do with this

The instinct to take the phone is understandable and I've written about what happened when I acted on it. The research doesn't particularly support cold-turkey removal as an effective strategy — it tends to increase conflict and isolation without addressing the underlying anxiety.

What tends to be more useful is treating the phone like any other variable in a complex system — worth looking at, worth adjusting, not worth going to war over. Some things that the evidence suggests are genuinely worth trying:

Screens out of the bedroom at night. This is the single most evidence-backed intervention. Not no phone — phone somewhere else overnight. The sleep mechanism alone makes this worth doing, separate from any other conversation about social media.

Looking at what she's actually consuming, together and without judgment. The content matters more than the time. A girl who is spending three hours on a platform that is actively feeding her comparison anxiety is in a different situation than a girl spending three hours watching cooking videos or building a following for something she's made.

Keeping the conversation open rather than closing it down. The goal is for her to be able to tell you when something she's seen has made her feel worse. That conversation can only happen if she doesn't expect you to respond by confiscating the device.

Working with her therapist on the social anxiety that makes the comparison trap particularly sticky. The platforms are the environment. The anxiety is the thing that makes the environment painful. Treating the anxiety directly is ultimately more effective than engineering the environment.

None of this is simple and I'm not going to pretend it is. But understanding the specific mechanisms — comparison, always-on social pressure, sleep — is more useful than a general sense that the phone is bad. It gives you something to actually work with.
