Social media, phones and teen mental health

Phones are where teens talk with friends, laugh, learn, and find people who share their interests. They are also where teens scroll late into the night, compare themselves with edited photos, and sometimes meet cruelty. Both things are true, and that is why the topic causes so many arguments at home.

This guide sorts out what the research shows, what is still unclear, and what has changed in 2025 and 2026, from Australia's under-16 law to phone bans in U.S. schools. It ends with practical steps for teens and parents.

What teens say about social media

A 2024 Pew Research Center survey asked about 1,400 U.S. teens and their parents how social media affects them.¹

Friendships were the one area where more teens saw benefits than harm. Girls were more likely than boys to say social media hurt their mental health (25% vs 14%), confidence (20% vs 10%) and sleep (50% vs 40%).¹ About 45% of teens said they spend too much time on social media, and 44% said they had cut back.¹

Signs that use is becoming a problem

Screen time alone does not tell the whole story. Experts look for signs that use is disrupting daily life:⁵

• Trying to cut back but not being able to
• Feeling upset, anxious or irritable when you cannot check your phone
• Lying about how much you use it
• Losing sleep, skipping homework, or missing time with friends and family because of it
• Feeling worse about your body or your life after scrolling
• Using your phone to escape every bad feeling

Our social media and mental health quiz can help you think about your own habits.

Why it affects teens so strongly

Growing brains, strong social needs. The teen years are a time when friends, status and belonging feel huge. Likes, comments and streaks tap right into that.

Design that keeps you scrolling. Endless feeds, autoplay and notifications are built to hold attention. The American Academy of Pediatrics (AAP) has asked companies to turn off autoplay and engagement-boosting features for children by default.⁶

Comparison. Looking at curated, edited images can feed poorer body image, disordered eating and low mood, especially among girls.⁵ See body image in the teen years.

Lost sleep. Using social media close to bedtime is linked to poorer sleep, and teens need at least 8 hours.⁵ See teen sleep.

Harmful content and contact. Teens can come across content about self-harm or eating disorders, or face hate and harassment.⁵ See bullying and cyberbullying.

What the research shows, and what it doesn't

The U.S. Surgeon General has warned that teens who spend more than 3 hours a day on social media face about double the risk of depression and anxiety symptoms. U.S. teens average about 3.5 hours a day.²

A 2025 study in JAMA followed about 4,300 U.S. children from age 10 for four years. It looked at addictive use, such as feeling unable to stop and use that caused problems at home or school. About 4 in 10 had high or rising addictive use of social media. Those children had roughly 2 times the risk of suicidal behavior compared with children with low addictive use. Total screen time at the start was not linked to later problems.⁴ This study shows a link, not proof that phones caused the problems. But it suggests that the pattern of use is a better warning sign than the number of minutes.

Social media can also help. It can offer support and closeness, especially for teens who feel isolated offline.⁵

New laws and school rules

• Australia began requiring 10 major platforms, including Instagram, TikTok, Snapchat and YouTube, to keep under-16s from having accounts on December 10, 2025. Platforms face fines up to A$49.5 million. Children and parents are not penalized.^7,8 Early results are mixed. About 4.7 million accounts were removed or restricted in the first weeks. But in a parent survey, about two-thirds of children who already had accounts on the biggest apps still had them. Regulators are investigating five platforms, and a two-year study of effects is under way.⁸
• U.S. schools. By March 2026, 33 states had passed laws limiting phones in K-12 schools. Some ban phones all day, others only during class.⁹ The AAP supports school phone policies that protect learning time.⁶ Research on how these bans affect mental health is still coming in.
• AI chatbots. The American Psychological Association has warned that teens may trust AI "companions" too easily and has called for safer defaults and limits on simulated relationships.¹⁰ A chatbot is not a therapist.

How social media affects mental health

The strongest concerns are about sleep loss, comparison, cyberbullying, harmful content and compulsive use.⁵ These can feed anxiety, low mood and poor body image. For many teens, the effect is small or mixed. For some, especially those already struggling, it can be large. If you see signs of depression or anxiety, read anxiety and depression in teens.

What helps

Steps to try this week

1. Check your numbers. Look at your phone's screen-time report. Which apps take the most time? When do you use them most?
2. Turn off non-essential notifications. Keep calls and messages from close friends and family. Silence the rest.
3. Pick a phone bedtime. Put your phone away at least an hour before sleep and charge it outside your room.¹¹
4. Do a feed audit. Scroll for 5 minutes and notice how each account makes you feel. Unfollow or mute three that leave you feeling worse.
5. Make one phone-free zone. Meals, the car, or homework time.
6. Plan what you'll do instead. Boredom is the hardest part. Have a book, music, a walk, or a grounding exercise ready.
7. If something upsetting happens online, take a screenshot, block, report, and tell someone you trust.²

For parents and caregivers

• Start with curiosity. Ask what your teen enjoys online and what bothers them. Teens are less likely than parents to see social media as the main problem, so listening first works better than lecturing.¹
• Match oversight to age. Closer adult supervision makes sense in early adolescence, with more independence as teens show they can manage it. A mix of limits and open talk seems to work best.⁵
• Make a plan together. Use the AAP's family media plan and think about content, what screens push out, and how your child is doing, not just minutes.⁶
• Model it. Put your own phone away at dinner and in the car.⁶
• Work with other parents. Shared rules, like no phones at sleepovers, are easier to keep.²
• Know the warning signs of problematic use, cyberbullying and depression, and act early.

Special situations

LGBTQ+ teens and teens who feel isolated. Online spaces can offer support that is missing at school or at home.⁵ At the same time, these teens may face more online hate. Look for moderated, supportive communities. See identity and belonging.

Teens with ADHD, anxiety or depression. Endless feeds can be harder to stop for teens who already struggle with focus or mood. Simple app limits and phone-free homework time can help.

Gaming. In the JAMA study, high addictive video game use was also linked to suicidal thoughts and behavior.⁴ The same signs of problem use apply.

Common questions

How many hours a day is too much?

There is no single safe number. More than 3 hours a day of social media has been linked to higher risk of depression and anxiety symptoms.² But how you use it, and what it pushes out, like sleep and friends, matters a lot.^4,6

Should I take my teen's phone away?

Taking it away as punishment can backfire and make teens hide problems. Shared rules, phone-free times and a plan made together usually work better.⁶ Keep calm and focus on sleep and safety.

Do school phone bans help?

They aim to protect learning time, and pediatricians support evidence-based school phone policies.⁶ Research on mental health effects is still coming in.⁹

Is it okay to talk to an AI chatbot when I feel down?

It may feel easier, but a chatbot cannot keep you safe or replace a person. Psychologists have warned that teens may trust AI too easily.¹⁰ Reach out to a person, or call or text 988 in a crisis.

When to get help

Talk with a doctor, counselor or therapist if:

• Phone use is causing fights, failing grades or lost sleep most nights
• You cannot cut back even when you want to
• You feel anxious, down or worthless after being online
• You are being bullied, threatened or pressured to share images
