It Starts With Understanding Your Own Nervous System
Your nervous system is a sophisticated, specialised collection of cells called neurons, the building blocks of the brain and the very things that let you think, imagine and decide what to do. Screens act directly on that system, which is why they affect us so powerfully. Rather than fixating on the number of hours, I encourage people to build a habit of checking in with their body while they’re using a screen, because their body registers the impact long before the mind admits to it.
A few reflective questions to ask yourself, in the moment:
Are my eyes feeling tired or strained as I scroll?
Is my mind feeling scattered or pulled in different directions by the constant images, colours and movement on the screen?
If I’m meant to be working or studying, can I actually account for the time I’ve just spent, and what I achieved in it?
How do I feel in my body right now: settled, or wired and restless?
And, most tellingly, do I feel better or worse than before I picked this up?
Asking yourself these questions regularly brings your awareness to the forefront and keeps you mindful of what you’re actually doing, rather than being carried along on autopilot. That awareness is the whole game, because you can’t change a pattern you haven’t noticed.
How To Spot When Screens Are Affecting Your Mental Health
The clearest signs are the ones your body and mood give you. Watch for how you feel afterwards: healthy use tends to leave you informed, connected or genuinely rested, while harmful use tends to leave you anxious, flat, irritable or oddly empty. Watch for displacement too, when screens crowd out the things that genuinely restore us: sleep, movement, real connection, time outdoors. And watch for that felt sense of compulsion, reaching for the phone without deciding to, a flicker of anxiety when it’s out of reach, or looking up to find forty minutes have vanished.
Underneath this is a nervous system story. The pings, the comparison, the endless novelty keep us in a state of low grade alertness, which keeps the body’s stress response gently switched on. Over time that can leave us wired but tired, struggling to settle, sleeping poorly, and more vulnerable to anxiety and low mood.
Spotting It In Children
With children the stakes are higher, because their brains are far more neuroplastic and their sense of who they are is still forming. They also can’t always put their distress into words, so it shows up in behaviour and in the body instead.
The signs I’d encourage parents to watch for: disrupted sleep or exhaustion that doesn’t match their day, big emotional crashes or irritability when the screen goes off, which signal the nervous system has become dysregulated by it, a loss of interest in the play, hobbies or friendships they used to love, withdrawal, low mood or anxiety, particularly around the social comparison of curated feeds, and physical clues like tired eyes, headaches or complaints of tummy aches. A helpful question for any parent is simply: does my child seem more themselves after screen time, or less? Children co-regulate through us, so a calm, curious parent noticing these patterns out loud teaches a child to notice them too, a skill that will serve them for life.
How To Talk To A Loved One About Their Screen Use
Gently, and from care rather than control. The fastest way to end this conversation before it starts is to lead with criticism, because the other person simply feels attacked and defends the behaviour rather than reflecting on it.
Choose the moment, not in frustration, not mid scroll, never as an ambush. Lead with the relationship, not the device: “I miss you in the evenings, I’d love more time with just us” reaches someone in a way that “you’re always on your phone” never will. Use your own feelings rather than accusation, as in “I feel a bit invisible when we’re both on our phones at dinner” invites reflection, where “you’re addicted to that thing” invites a wall. And get curious instead of delivering a verdict: ask what they get from it, whether they’re happy with the balance. People change far more readily when they reach their own conclusions than when someone hands them one.
This mirrors the framework I use clinically, the Three A’s. Awareness, helping someone gently notice their own pattern without shame. Acceptance, meeting it with compassion, because heavy screen use is almost always soothing something underneath: stress, loneliness, boredom or avoidance, and shaming it only deepens the distress. And Authentic Communication, moving from blame to an honest need, so the conversation becomes “here’s what I feel and what I’d love for us,” not “here’s what you’re doing wrong.”
And one vital caveat, for adults and children alike: if the screen seems to be masking something deeper, like anxiety, low mood or isolation, then the screen is the symptom, not the cause. In those moments the kindest response isn’t to police the device but to gently address what’s underneath, with professional support if it’s needed.
