As a parent, you want your teen’s online world to be a space for making friends and being creative. However, the internet can also be a place where mean interactions happen. If you have noticed changes in your teen’s mood or behavior after they spend time on their phone, you may be wondering: how does cyberbullying affect mental health?

Cyberbullying involves repeated unwanted aggressive behavior, observed or perceived power imbalance through digital platforms. This may include harassment, rumors, threats, exclusion, sharing embarrassing content or repeated negative comments online.

Not every upsetting online interaction is cyberbullying. However, repeated online mistreatment may affect a teen’s emotional well-being, confidence and sense of safety. Learning how these experiences affect the mind is the first step in helping your teen stay safe online.

Why cyberbullying can feel especially overwhelming for teens

Because this digital world is so integrated into their lives, this type of bullying can feel like it never ends, unlike traditional bullying that ends with the last bell of the school day. Messages, posts or comments can follow teens into their homes and private spaces through phones, apps and social media.

Teens may also feel pressure to stay connected online socially, even when those spaces become emotionally harmful.

Some teens avoid telling adults because they fear:

• Losing phone or internet privileges
• Being blamed
• Feeling embarrassed
• Making the situation worse

This is one reason parents may not notice emotional changes right away.

5 ways cyberbullying affects teen mental health

1. It increases feelings of worry and social withdrawal.

Cyberbulling may contribute to a teen feeling anxious, distressed, afraid, avoidant or hypervigilant. When a teen feels targeted online, they may start to feel like the world isn’t a safe place. This high alert feeling can cause emotional and physical stress. To identify if your teen is struggling with heightened anxiety, watch for these behaviors:

• Fearing phone alerts — Some teens feel their heart race or get nervous every time their phone makes a sound.
• Avoiding activities — To cope, a teen might stop going to school, skip sports or stop hanging out with friends they used to like.
• Experiencing physical signs — Stress can cause stomachaches, headaches or changes in how much they eat.

2. It can create a lingering low mood and signs of sadness.

Being picked on online is often linked to low self-esteem and a sad mood that won’t go away. Unlike bullying in person, cyberbullying can be seen by many people at once, which can make a teen feel even more ashamed. To understand how online harassment impacts your teen’s emotional state, look for these shifts:

• Feeling hopeless — Because it is hard to delete things from the internet, a teen might feel like the situation will stay bad forever.
• Losing interest — You might notice your teen stops caring about hobbies or things that used to make them happy.
• Experiencing sleep problems — Stress can make it hard to fall asleep, or it might make a teen want to sleep all day to avoid their problems. 

If your teen is struggling with thoughts of self-harm, suicide or feels unsafe, call or text 988 Suicide & Crisis Lifeline or call 911 for immediate support.

3. It interferes with cognitive focus and school performance.

The heavy feeling of being bullied online can take up a lot of brain space. When a teen is always worried about what people are saying about them, they often have a hard time focusing on school. You might notice your teen’s academic life is being affected if they are:

• Showing a drop in grades — A sudden decline in academic performance can be a sign that a teen is dealing with significant emotional stress.
• Having difficulty paying attention — They might seem distracted or have a hard time following a simple conversation.
• Finding it hard to stay organized — Tasks like planning, organizing, and finishing homework may feel much more difficult than they used to be.

4. It can lead to higher risks of self-harming behaviors.

In very serious cases, the emotional pain of cyberbullying can feel so big that a teen looks for ways to deal with the hurt. While this doesn’t happen to every teen who is bullied, there is a link between online harassment and a higher risk of self-harm. To help protect your teen’s physical safety, stay alert for signs that they are: 

• Using unhealthy ways of coping — Some teens might hurt themselves as a way to let out emotional pressure or numb the pain.
• Acting without thinking — Intense distress, humiliation or hopelessness may increase the risk of impulsive reactions to painful feelings.
• Showing physical warning signs — If you see your teen wearing long sleeves in hot weather or notice marks that can’t be explained, it may be helpful to get professional help right away. 

5. It causes changes in self-perception and identity.

The teen years are a big time for figuring out who you are. Cyberbullying can interrupt this by making a teen believe the mean things said about them instead of their own thoughts. This internal struggle often causes a teen to:

• Develop a negative self-view — They might start to believe that the hurtful comments made about them are actually true.
• Feel deeply ashamed — They may feel like the bullying is their fault or that they did something to deserve it.
• Pull away from friends — They might stop hanging out with good friends because they feel like they don’t fit in anymore.

How parents can help their teen feel better

If your teen is being bullied online, the most important thing you can give them is a safe, kind place to talk. It might be tempting to take their phone away right away, but this can make a teen feel like they are being punished for someone else’s mean behavior. To support your teen through this process, try these helpful strategies:

• Listen first — Let your teen talk about what is happening without interrupting them or trying to fix everything immediately.
• Save the evidence — Tell your teen to take screenshots of the mean messages or posts instead of deleting them.
• Encourage offline fun — Help them find activities away from screens that make them feel confident and happy.
