Social media addiction symptoms in teenagers

The previous page covers what you can see. This one covers what they’d tell you.

Sleep

Not just less of it. Broken sleep, waking to check, lying awake after putting the phone down, and a tiredness that a long weekend doesn’t touch.

Ask what happens after they turn the light off. Ask whether they wake up in the night, and what they do when they do. These questions get honest answers more often than “how much are you on your phone,” because they aren’t about the phone.

Tiredness, headaches, eye strain, aching hands

Ordinary and easily missed, because they’re the sort of thing a teenager mentions once and doesn’t repeat. Worth asking about directly.

Anxiety around checking

Some young people describe a specific, physical feeling when they haven’t checked for a while — restlessness, a pull to look, an unease that settles the moment they do. Others describe dread before opening an app and relief afterward, or the reverse.

If your child can describe something like that, it is worth telling whoever assesses them. It’s specific, and specific is useful.

Low mood, and mood that moves fast

Flat affect. Irritability out of proportion. Crying they can’t explain. A mood that lifts and drops within an hour.

The version that matters most is a young person who is reliably worse after use than before it and knows it, and uses anyway. That gap — knowing and continuing — is worth naming to a clinician.

Eating and appetite

Changes in eating are worth attention and they’re also the area where parents most often make things worse by watching closely and saying so.

What to notice: eating at different times, skipping meals, a new interest in what food contains, eating alone when they used to eat with the family, or discomfort at the table that wasn’t there before.

What not to do: comment on their body, comment on the amount, or start monitoring. If you’re worried about eating, the useful move is a call to someone qualified, not a conversation at dinner.

The National Alliance for Eating Disorders answers on 866-662-1235, weekdays 9am to 7pm Eastern. Outside those hours, 988.

Comparison, and how it shows up in what they say

Not a symptom so much as a thing you’ll hear. Offhand remarks about how they look, about other people’s lives, about being behind. Teenagers say these things lightly and often mean them.

If the remarks are frequent, if they’ve hardened from self-deprecation into something flatter, or if they’ve started avoiding photographs and mirrors, that’s a change worth writing down.

When a symptom is urgent

Some things don’t wait for an appointment.

If your child has talked about not wanting to be here, has said the people around them would be better off, has given things away, or if you’ve found evidence they’ve hurt themselves — call or text 988 today. Not next week, and not after you’ve decided whether it’s serious. That’s what the line is for, and you can call about someone else.

You can also ask them directly whether they’re thinking about hurting themselves. Asking does not put the idea in their head.

How to ask without it becoming an interrogation

Ask about one thing, not everything. Ask when you’re doing something else — driving, washing up, walking. Ask about the symptom, not the phone. Accept a short answer without following it up immediately.

A teenager who says “I don’t know” has not refused. They’ve bought time, and they’ll often come back to it hours later if you let them.

When to worry and when it’s normal — because most of what’s on this page appears, at some level, in ordinary adolescence.

Finding a therapist if you’ve read enough.
