Bodies on social media: what constant comparison does

“I wasn’t having a bad day. Really, I wasn’t. Then I lay there with my phone for ten minutes and got up feeling that something is badly wrong with me.”

I have heard versions of this sentence so many times that I almost expect it. What is interesting about it is not that people feel worse after social media. Everyone knows that. What is interesting is how precisely they can name the moment it happened, and how little time it took.

In this piece I am not interested in a moral argument about phones. I am interested in the mechanism: what exactly happens in those ten minutes, and why it happens far more to some people than to others.

Comparing is not, in itself, a fault

In 1954 Leon Festinger described something simple: we have no absolute yardstick for ourselves. We do not know whether we are clever, capable or attractive until we compare ourselves with someone. Comparison is how we locate ourselves in the world at all.

That is not a design flaw. It is a useful instrument that tells us where we are and points at where we might go. The problem is not comparison. The problem is what we compare with, and how many times a day.

Festinger distinguished upward from downward comparison. Upward comparison can inspire, if a person is in a state where they believe the gap is bridgeable. If they do not believe that, the same comparison works as proof of their own inadequacy.

What a feed does that a street does not

Three shifts, each small on its own, and not small together.

First, selection. On the street you see people in every state. On a feed you see almost exclusively what was chosen, out of many attempts. You compare your entire everyday reality with someone else’s selected, arranged and often edited moment.

Second, volume. The number of comparisons a person makes in a day is now incomparably higher than at any earlier time. Each one is small; the sum is not.

Third, the absence of context. When you know someone, you know what things cost them. When you only see them on a screen, you know nothing — and the empty space fills up with the assumption that they find it easier than you do.

What the research shows

Jasmine Fardouly and Lenny Vartanian reviewed the field and arrived at a fairly consistent picture: use of image-based platforms is associated with greater body dissatisfaction, and what matters is the kind of use rather than the amount of time. People who browse other profiles and compare report feeling worse; people who use the platforms to talk with people they know, much less so.

It is worth knowing that comparison does not stop at strangers. It hurts most with people you know — a classmate, a colleague, a cousin. Fardouly and colleagues found exactly this: comparison with close acquaintances is more strongly associated with dissatisfaction than comparison with celebrities. A famous person is too far away to be a yardstick. A colleague is not.

Marika Tiggemann and Amy Slater showed in adolescent girls that the association with body concern was stronger for social media use than for general internet use. So it is not the screen, it is the content.

The most telling study is the experiment by Mariska Kleemans and colleagues. Adolescent girls were shown photographs that were either original or manipulated. Those who saw the manipulated ones reported a poorer image of their own bodies — and the great majority did not notice that the photographs had been altered at all. That is the part that interests me most as a therapist: the effect does not require awareness.

Why it happens so fast

People often say their mood changed “instantly”, and they are right. Humans process faces and bodies extremely quickly and largely automatically. This is not a deliberation that could be intercepted with an argument.

That is why the reassurance “you know the pictures are edited” is so ineffective. Knowing is slower than reacting. It arrives once the feeling is already here, and then it often adds a second layer: now the person feels bad and is ashamed of feeling bad about something so silly.

That second layer is often the harder part in therapy. The first feeling passes by itself. The second stays, because it is carried quietly and never told to anyone.

“Health” as packaging

Content labelled as healthy is often the most problematic, precisely because it triggers no defence. Nobody guards themselves against advice about exercise.

Research on so-called fitspiration content shows that exposure to these posts lowers women’s body satisfaction much as classic advertising imagery does, although the message is ostensibly about strength and health. “Look after yourself” reads, in practice, as “your body is an unfinished project”.

In therapy I often see this in people who would say they are not interested in appearance. They are interested in health, discipline, order. The word has changed; the inner voice has not — it is the same inner critic, just better dressed.

The algorithm does not choose neutrally

Here is something classic media lacked: a feedback loop. If you linger on a certain kind of content, you get more of it. The system does not know whether you lingered because it pleased you or because it hurt. All it registers is that you stopped.

The consequence is that a person in distress gradually acquires a feed that confirms their distress. Someone sensitive about their body will see more bodies. This is not a conspiracy; it is a system doing exactly what it was built to do.

This is why the advice “just spend less time on your phone” so often fails. The question is not how much but what — and what has accumulated in your feed while you were not looking.

Where the research does not support the panic

Now the part where I have to contradict myself.

In a large analysis of major datasets, Amy Orben and Andrew Przybylski showed that the association between screen use and adolescent wellbeing is, on average, very small — comparable to effects nobody treats as a public health crisis. Their work matters because it demonstrates how much the result depends on which variables a researcher happens to choose.

Beyond that, most studies are correlational. It is entirely possible that adolescents who feel worse use social media more, rather than the other way round. Most likely both are true at once.

And something else that gets lost in the debate: for some people these platforms are the only place where they have found anyone like themselves. For an adolescent in a small town who is different, that is not a trifle. If I talk about social media only as harm, I am not telling that person the truth.

All of which means there is no answer to the question “is social media harmful”. There is only an answer to the question of what a particular kind of content does to a particular person at a particular point in their life. That is a less appealing headline, but it is the only thing that is true.

So I do not write about averages. I write about who is harmed more.

Who is harmed more

This part matters more than the general findings. The same post does not do the same thing to two people.

Vulnerability is not evenly distributed. More exposed are people who already carry body dissatisfaction, who are prone to rumination, who have low self-worth, and who are in a period of rapid physical change — that is, adolescents.

With them it also becomes clear how much depends on what a person does with the comparison afterwards. If it ends in rumination that lasts all evening, the effect is entirely different from a single moment of discomfort that then passes.

In people who received remarks about their bodies in childhood — at home, at school, in sport — the response is usually stronger. The post does not land on empty ground; it lands on something built long before.

And in eating disorders, social media can be an active maintaining factor — not a cause, but something that delivers the illness fresh material every day. In treatment we touch on this sooner rather than later.

What I do with this in therapy

I do not suggest disconnecting. I suggest curiosity: what happened just before you picked up the phone. There is almost always something uncomfortable alongside it — boredom, anxiety, an empty evening, an argument. The feed is often the fastest available escape from whatever would otherwise have to be dealt with.

Many people expect me to hand them rules of use. I do not, because rules about screens work exactly like rules about food: for a while, and then they collapse and leave behind a sense of defeat. What holds up better is understanding what the scrolling was doing for you.

Then we look at what happens inside you during the comparison. For many people it turns out not to be a thought about the body but shame — a sense that something is wrong with you as a whole, not with one attribute.

And then we work on the only genuinely protective thing: how you speak to yourself afterwards. Positive thinking does not help here. Self-compassion does, and it is less pleasant and more useful.

If you are a parent

Prohibition rarely works, because contact with peers happens there. What works better is becoming the person your child tells about what they have seen.

Children respond far more to whether a parent can hold a conversation without panicking than to any ban. If you take fright at the first mention, you have lost the information you would have been given the second time.

Practically: do not comment on appearance — not theirs, not your own, not anyone else’s. Children learn their relationship with their body from how a parent speaks about their own. And if you notice changes in the relationship with food, do not count on it passing. For adolescents the recommended first choice is family-based treatment, and where medical risk appears, the first address is a doctor.

What to remember

Comparison is not a fault but the way we locate ourselves. Social media simply multiplies it and makes it unequal: your whole day against someone else’s chosen frame.

What is decisive is not the amount of time but the kind of use. Browsing and comparing does harm; talking with people you know, far less.

The effect does not require your awareness. “I know it’s edited” is therefore not protection.

The averages are small, and individuals are not averages. If you are vulnerable to this, the question is a serious one even when it disappears in large studies.

What protects you is not better judgement about pictures. It is what you do with what you feel afterwards — whether you move on or stay in it all evening.

And the most useful measure is simple: which account do you get up from feeling worse. Start there.
