Social media and self-esteem: the evidence

What is actually known

The honest summary of a large and messy research field: for most young people, moderate social media use has small effects either way. For some, heavy use is associated with worse mood, worse sleep and worse self-image. And the direction is not simple, because unhappy teenagers also use social media more. The strongest and most consistent finding is about sleep, and the second is about comparison.

Who is more vulnerable

Neurodivergent teenagers, on the whole. Rejection sensitivity makes a slow reply feel like a verdict. A literal mind takes edited lives at face value. Impulsivity posts before thinking. Hyperfocus makes putting it down harder. And a child who already feels different has an endless feed of evidence that everyone else is the same.

What helps

Phones out of bedrooms overnight, for everyone in the house, which protects the sleep finding almost entirely. Conversation about what a feed is: curated, edited, chosen, not a window into anyone's real life. Following accounts that make them feel better and unfollowing the ones that do not, as an explicit skill. And time offline that is not framed as punishment: sport, a club, an interest with real people in it.

What does not

Blanket bans for teenagers, which mostly move the use out of sight and remove you from the conversation. Reading their messages without their knowledge. Panic. The relationship is the protective factor. A child who will tell you what they saw is safer than one who will not.
