GardionSocial media and teen anxiety: what the research says and what parents can do
Researchers do find a link between social media, anxiety and self-esteem in teens. On average it is weak, and it varies a lot from one teen to the next. Nobody has yet shown that these apps caused the rise in teen anxiety. That is the heart of the debate: psychologist Jonathan Haidt sees social media as the main cause, while Candice Odgers, Amy Orben and other researchers argue that the data don't support that conclusion. You don't have to wait for the debate to end. Both sides agree that early adolescence is a more vulnerable time, that phones shouldn't eat into sleep, and that comparing your looks with other people's photos hurts self-esteem. Below we lay out each side's case, why they disagree, and what you can do at home now. For the bigger picture, from habit to disorder, see the main article in this series.
What Haidt argues and how critics respond
The best-known book on the subject is The Anxious Generation (2024) by social psychologist Jonathan Haidt. In his view, childhood moved from the playground into the phone, and that shift set off a youth mental health crisis. He proposes four new norms: no smartphone before high school (around age 14), no social media before 16, phone-free schools for the whole day, and more independence and free play. He describes social media as a firehose of social comparison and algorithm-picked influencers that hits kids during their most vulnerable years.
In the journal Nature, psychologist Candice Odgers reviewed the book. She has studied adolescent mental health for about twenty years. In her reading, science doesn't support the claim that digital technology is rewiring kids' brains and driving an epidemic of mental illness. Hundreds of researchers, Odgers among them, went looking for the large effects Haidt describes and found links that were zero, small or mixed. When studies follow teens over time, the link more often runs the other way: teens who already struggle tend to use social media more, or differently. Odgers points to broader causes of the crisis, such as poverty, violence, discrimination and too few school psychologists.
The disagreement isn't black and white. Odgers writes that platforms still need serious reform, and she calls some of Haidt's ideas reasonable: stronger content moderation and building a user's age into how platforms are designed. Her objection is to age-based bans. She doubts they would work in practice and warns they could backfire on teens themselves.
| Haidt | Odgers, Orben and colleagues | |
|---|---|---|
| Main claim | Smartphones and social media caused the teen mental health crisis | The data don't show social media caused it |
| What they look at | How childhood changed: less freedom outdoors, less protection online | Studies that follow the same teens over time, meta-analyses |
| What they propose | Smartphone at 14, social media at 16, phone-free schools | Reform platforms, look for other causes, support vulnerable teens |
Why scientists can't agree
The first reason is the data. Most studies survey teens once: how much time do you spend on social media, and how do you feel? A survey like that shows two things happening together. It can't tell you which one is the cause. Most research on short videos and attention is built the same way; we walk through it in our guide to short attention span in kids.
The second is the direction of the link. Amy Orben and colleagues at Cambridge and Oxford followed thousands of young people in the UK between ages 10 and 21. Those who used more social media were slightly less satisfied with life a year later. It also worked in reverse: teens whose life satisfaction dropped went on to use social media more. The U.S. National Academies of Sciences, Engineering, and Medicine reached a similar view in a report released in December 2023. Most studies, they wrote, can't separate social media affecting a teen's health from a teen's health affecting how they use social media.
The third is that teens differ. An average blends them into one number. A team in the Netherlands led by Patti Valkenburg asked 387 teens aged 13 to 15 about social media and self-esteem six times a day for three weeks. For most of them, self-esteem barely moved. A small group felt better, and another small group felt worse. Averaged out, the effect looks like almost nothing. For a teen in that second group, it is very real.
We find the National Academies' conclusion the most level-headed one in this debate. There isn't enough evidence to say social media changes adolescent health across a whole generation. It can still help or harm individual teens. That is why the committee recommends a careful approach and stops short of a blanket ban.
Social media and teen self-esteem: the comparison trap
The clearest risk involves comparing appearance. In its 2023 health advisory, the American Psychological Association (APA) recommends that teens limit using social media to compare themselves with others, especially around beauty and appearance. These comparisons, along with close attention to one's own photos and the reactions they get, are linked to poorer body image, disordered eating and symptoms of depression. The pattern is strongest among girls. Why a teen's brain reacts so strongly to likes is covered in our article on the dopamine crash myth.
The U.S. Surgeon General's 2023 advisory on social media cites another study. Among American teens aged 12 to 15, those who spent more than three hours a day on social media later had double the risk of depression and anxiety symptoms. The researchers accounted for how the teens were doing at the start. It is a single cohort study, and it shows a link, not a cause.
The same advisory also shows the other side. More than half of teens in surveys say social media helps them feel accepted, find support through hard times and share their creativity. For a teen who struggles to find their people at school, online friends can be a real lifeline.
What this means at home is simple. Pay attention to what your teen sees on social media and how they seem afterward. A stream of other people's perfect photos is one thing. A group chat with teammates is something else entirely.
Where both sides agree
Early adolescence is more sensitive. In Orben's study, the link between social media and life satisfaction was strongest in younger teens, with "windows of sensitivity" at ages 11 to 13 for girls and 14 to 15 for boys. Haidt also calls early puberty the most vulnerable stretch. They disagree about how big the harm is. Their sense of when to pay closer attention is nearly the same.
Sleep comes first. The APA advises keeping social media from interfering with sleep and physical activity, and says teens need at least eight hours of sleep. Our article on phones before bed goes into more detail.
Platforms need to change. Haidt, Odgers and the authors of the Surgeon General's advisory all say so. We looked at why endless scrolling is so hard to put down in our piece on doomscrolling in teens.
Australia has gone furthest down Haidt's path. Since December 10, 2025, major social media platforms there must stop users under 16 from having accounts. The regulator puts it this way: "It's not a ban, it's a delay to having accounts." The platforms carry the responsibility, and teens and parents face no penalties. Whether the delay works will become clear over the next few years.
What parents can do now
We'd start with your own teen and leave the studies in the background.
If your teen seems low after social media, stops seeing friends, sleeps badly and can't stop scrolling, read our guide to signs of phone addiction. Crying, saying "I'm worse than everyone," or talk of self-harm are reasons to get professional help right away. In the U.S., you or your teen can call or text 988 to reach the Suicide & Crisis Lifeline.
- Ask how they feel when they come off social media: what they watched, what mood they were in when they put the phone down. That answer tells you more than an hour count.
- Talk about comparison. Photos get edited, posts show the best of other people's lives, and the algorithm serves up more of what they've already watched. The APA recommends teaching this before a teen opens an account.
- Stay close between ages 10 and 14. For this age, the APA recommends that adults review what their child sees on social media, talk it through and offer guidance, then add freedom step by step as the teen learns. Monitoring, the APA adds, should respect a teen's need for privacy.
- At night, keep the phone away from the bed. Sleep is the point researchers argue about least.
- Decide on the age for a first account as a family. Haidt recommends waiting until 16, Australia has put that into law, and Haidt's critics doubt a ban helps. If you decide to wait, explain why and give your teen a date.
Setting a limit on one social app in Gardion
In Gardion, our parental control app, you can set a limit on a single app. If your family decides evenings go to one social app, the limit applies only to that app. Messaging with classmates and maps keep their usual settings.
When the minutes run out, your teen can ask for more. You answer from your own phone, granting extra time or declining. Every answer is saved in Time requests, so after a week you can see what your family actually agreed on.
For a guide to daily hours by age, try the screen time calculator. To install Gardion on your child's phone, see parental controls for Android.

In short
There's no evidence that social media causes anxiety in teens across the board. Researchers find a link, but it's weak and often runs both ways: teens who already feel bad tend to use social media more. For some teens, social media does make their mood worse, so watch your own child.
For most teens, social media barely changes self-esteem. For a small group it rises, and for another small group it drops. Comparing your looks with other people's photos does the most damage, especially among girls.
There's no single standard. Haidt recommends waiting until 16, and since December 2025 major platforms in Australia can't give accounts to anyone under 16. The APA recommends that between ages 10 and 14 parents stay involved and add freedom gradually.
It's Jonathan Haidt's 2024 book arguing that smartphones and social media caused the teen mental health crisis. Critics, including Candice Odgers in Nature, say the data don't show such a strong link and that the crisis has other causes too.
Science doesn't have an exact cutoff. In one U.S. cohort study, teens who spent more than three hours a day on social media had double the risk of depression and anxiety symptoms. Compare the hours with your teen's sleep and with what social media has pushed aside.
