Online violence and teenage wellbeing

At a glance

Online violence isn’t just graphic videos. It’s also content that involves humiliation, threats, sexual intimidation, cruelty and harm presented as entertainment.
Teenagers often come across it without looking for it – through group chats, social feeds, gaming and algorithm¹-driven content platforms.
You might notice changes in sleep, mood, behaviour or language, rather than a clear link to something they’ve seen.
Repeated exposure can make cruelty seem more normal, especially when it’s shared as humour or shown without consequences.
Girls and boys often experience online violence differently – girls are more likely to face sexualised aggression and scrutiny, while boys may be drawn into cultures that reward dominance and hostility.

What is online violence

Most adults picture violent content purely as something physical – fights, attacks or war footage. But it’s often more subtle and more constant:

Graphic videos on social media
Group chats sharing disturbing clips
Livestreamed real-world violence
Humiliating ‘fail’ videos
Memes built around cruelty or dominance
Cyberbullying and pile-ons
Sexual threats or coercion²
Violent or degrading language
Gaming spaces with constant aggression and humiliation
Content that’s pushed repeatedly because it shocks or provokes

A lot of this content isn’t searched for – it just appears. And the online world rarely shows this kind of content just once. The same messages often reappear across different pieces of content day after day, week after week.

Context still matters

Not all violence is the same. Stories, films and games usually present conflict as part of a story with consequences and some sense of right and wrong.

More concerning is violent content that’s shared on its own, purely for shock or entertainment. When violence is stripped of context or treated as funny or consequence-free, it can make harm easier to laugh off or ignore.

The question isn’t just “Have they seen violence?” but “What kind, how often and what message came with it?”

What you might notice

Not every teenager will react in the same way. Some may seem completely unfazed; others won’t say if something they’ve seen has affected them. Instead, you might notice:

Irritability after being online
Trouble sleeping or nightmares
Being more on edge or jumpy
Replaying images in their mind
Harsher or more aggressive language
Joking about violent content in a way that feels off
Going quiet or withdrawing after screen use
Being unusually watchful or tense

None of these on their own prove anything. But if you’re seeing a pattern, especially linked to time spent online, it’s usually worth gently exploring what’s sitting behind it.

When violence starts to shape behaviour

Online spaces can turn aggression into something that looks normal, powerful or even entertaining.

This matters because teenagers are still working out what’s normal. So if humiliation repeatedly gets laughs, aggression constantly gets attention and cruelty is always rewarded – those messages can start to stick.

Harshness begins to look like strength, vulnerability seem embarrassing and dominance looks like something to be admired.

Girls and young women

Girls and young women are often affected by online violence in more than one way. Some experience it directly, through harassment, pressure or intimidation. But they may also be repeatedly exposed to content where women are humiliated, objectified, threatened or treated as less important.

Over time, this can make online spaces threatening. Some girls stop posting, or keep details to themselves, or start second-guessing what they say and share, just to avoid the attention.

It can also affect how they see themselves, what they put up with and what they consider ‘normal’ in a relationship.

Boys and young men

Some boys are drawn into online spaces where hostility, dominance and control are framed as strength. This is especially visible in manosphere³-style content, such as:

Language that demeans girls or other groups
Humour built around humiliation or aggression
Rewarding harshness and glorifying dominance

Not every teenage boy is affected in this way. But for some, seeing this approach to others makes it hard for them to express anything other than anger or detachment, and can shape ideas about masculinity, respect and relationships.

What to do

Stay calm

If they think you’re going to react strongly, they may keep their thoughts and feelings to themselves.
Don’t assume they looked for it

A lot of it just appears through algorithms. 
Be curious, not accusatory

“Have you seen much of this stuff going around online?” keeps things open.
Name the behaviour you’re noticing

“You seem more on edge after being online lately” is often easier for them to respond to.
Talk about the message

“What do you think that says about how people treat each other?” helps them think, not just react.
Be clear about boundaries

“Being angry is one thing, but humiliating or threatening someone isn’t okay.”
Keep an eye on group chats

A lot of the worst content is shared in group chats or between friends.
Put limits where needed

This might include no phones late at night or time out from certain platforms.
Offer alternatives

Exercise, sport, music – or just a clean break – can help reset things.
Keep coming back to the conversation

Try to talk through what they’re seeing, how feeds and algorithms work, and what is acceptable and unacceptable behaviour.

When to look for further help

It may be time to get some extra help if what they’re seeing online seems to be leading to:

Sleep problems or nightmares
Getting stuck on distressing images
Becoming more aggressive or cruel
Pulling away from other people
Seeming constantly on edge
Cyberbullying, harassment or coercion
Things starting to go downhill at school, in friendships or at home
Time spent in online spaces, or with people, where violence is brushed off, laughed at or encouraged

What to remember

Most teenagers will come across violent content online at some point. This doesn’t mean they’re violent. What matters more is whether it starts to shape what they see as normal or okay. Keep conversations open and be clear about what’s okay and what isn’t – it can make a big difference.

Footnotes:

¹Algorithm – the rules a platform uses to decide what content to show someone, often based on what they’ve watched, liked, clicked on or spent time viewing.

²Sexual intimidation and coercion – pressure, threats or manipulation used to make someone feel scared, controlled or pushed into doing something they don’t want to do.

³Manosphere – a loose online network of forums, influencers and communities that often promote hostile or exaggerated ideas about masculinity, women and relationships.
