Teens and Social Media: Warning Signs for Parents

Social media is a big part of most teenagers’ lives, and much of it is positive: friendships, creativity, support and a sense of belonging. But for some teens, it chips away at sleep, mood and self-esteem, or exposes them to bullying and exploitation. The most useful signals for parents aren’t hours on a screen alone, but changes: sleeping less, seeming low after scrolling, pulling away from people and activities, or becoming secretive and distressed about their phone.

What the experts say

In 2023, the US Surgeon General issued an advisory on social media and youth mental health. It concluded that there isn’t enough evidence to say social media is sufficiently safe for children and adolescents, and highlighted research finding that adolescents who spend more than three hours a day on social media face double the risk of poor mental health outcomes, such as symptoms of depression and anxiety. The same year, the American Psychological Association advised that use should be monitored and adjusted to a teen’s maturity, and that it shouldn’t interfere with sleep or physical activity.

The research is still developing, and effects vary a lot between young people. Some benefit from online communities, particularly those who feel isolated offline. That’s why paying attention to your own child matters more than any single rule.

Warning signs to watch for

Signs of bullying, grooming or sextortion

Some changes point to specific online harms:

• Cyberbullying: upset after checking messages, avoiding school or certain friends, not wanting to talk about their online life.
• Grooming: a new older “friend”, gifts or money from unknown sources, secret accounts, being asked to move chats to private apps.
• Sextortion: sudden fear, panic or withdrawal, requests for money or gift cards, talk of having “made a mistake”.

Sextortion can escalate quickly. Make sure your teen knows they won’t be in trouble for telling you, and that help is available to remove images. Our sister site’s online safety checklist for parents explains the steps to take.

How to talk about it

• Start with curiosity. Ask what they enjoy, who they follow and what they’d change.
• Share your own habits. Admitting your own scrolling makes it a shared challenge, not a lecture.
• Avoid instant punishment. If telling you leads to losing the phone, teens may stop telling you.
• Talk about how feeds work: algorithms, filters and edited images. Understanding the design helps teens resist it.
• Keep checking in, briefly and often, rather than one big talk.

Practical steps that help

• Protect sleep: phones charge outside the bedroom overnight; see our guide to a phone-free bedroom.
• Agree rules together, such as device-free meals and homework time, in a family tech agreement.
• Use built-in tools: teen accounts, time limits and privacy settings; see Screen Time on iPhone and Digital Wellbeing on Android.
• Tame the feed: turn off autoplay and unnecessary notifications; our guide to taming notifications shows how.
• Encourage offline anchors: sport, clubs, part-time work and time with friends in person.
• Model it: teens notice when adults check phones at dinner; see our guide to phubbing.

Rules around the world are changing

Governments are tightening protections. In the UK, Ofcom’s children’s safety codes under the Online Safety Act took effect in 2025, requiring platforms to protect children from harmful content. In Australia, a minimum age of 16 for many social media accounts began in December 2025. Rules and features change often, so check the latest settings on each app your teen uses.

When to get help

Contact your GP, family doctor or school counsellor if:

• low mood, anxiety or withdrawal lasts more than a couple of weeks
• you notice self-harm, talk of hopelessness or changes in eating
• bullying or exploitation is affecting their safety or school life

If a young person is at immediate risk, call emergency services. In the UK, young people can call Childline free on 0800 1111, and anyone can call Samaritans on 116 123. In the US, call or text 988 for the Suicide and Crisis Lifeline.

Frequently asked questions

How much social media is too much for a teenager?

There’s no single safe number, but the US Surgeon General highlighted increased risks for teens using social media more than three hours a day. Watch for effects on sleep, mood and daily life.

Should I take my teen’s phone away?

Sudden bans can backfire and make teens less likely to tell you about problems. Agreed limits, phone-free bedrooms and ongoing conversation usually work better.

What are the signs of cyberbullying?

Being upset after going online, avoiding school or friends, secrecy about devices and reluctance to talk about online life can all be signs.
