Most of us have heard that screens before bed are bad for sleep. Fewer of us have stopped doing it. And the reason for that gap between knowledge and behaviour is worth understanding, because it suggests that willpower alone isn't really the solution.
The issue with screens in the evening isn't simply the blue light – though that's part of the picture. It's also the content: the novelty, the social comparison, the emotional stimulation, the unfinished threads of news and conversation. Screens are designed to keep us engaged, and they do so with remarkable efficiency. Putting them down requires us to offer the brain something else – something that feels genuinely satisfying rather than like a sacrifice.
What's actually happening in the brain
In the hours before sleep, the body's melatonin production begins to rise – a signal that the day is ending. Light, particularly the short-wavelength blue light emitted by phone and laptop screens, suppresses this process. The brain interprets blue light as a signal of daytime, keeping melatonin low and the system in a more alert state.
But beyond the light itself, the cognitive and emotional stimulation of screen content keeps the prefrontal cortex active in ways that don't naturally lead towards sleep. Many people lie awake not because of light, but because their minds are still processing the last thing they were watching or reading.
"The brain doesn't switch off – it winds down. Giving it the right conditions for that process is one of the most useful things you can do."
What tends to work instead
Reading a physical book is one of the most consistently reported alternatives, and it's not just nostalgia. The engagement is real but contained – a story moves at a pace you control, ends at a natural point, and doesn't send notifications. Many people find that even twenty minutes of reading shifts the quality of their sleep quite markedly. If the book is genuinely absorbing, even better – it keeps the mind just busy enough to stop it looping on the day's concerns.
Listening to something – a podcast, an audiobook, music – keeps the mind gently occupied without any visual stimulation. Many people find this a useful middle step if the transition from screen to nothing feels too abrupt. The key is choosing content that's engaging but not activating: a natural history documentary in audio form rather than true crime, for example.
A brief journalling practice – even just ten minutes with a pen and paper – can help the mind deposit the unfinished business of the day somewhere external, rather than holding it in memory overnight. There's no particular format required; even a list of what's on your mind can reduce the sense of things needing to be kept track of.
A simple craft or creative activity – knitting, drawing, colouring, anything repetitive and slightly absorbing – occupies the hands and a portion of the attention in a way that many people find genuinely restful. These activities have a satisfying tactile quality that screens don't, and they have a natural endpoint when you choose to stop.
On managing the transition
The hardest part of reducing screen time in the evening is that screens are habitual – they fill the spaces that would otherwise feel empty. Many people find it useful to set a gentle boundary (a time after which the phone stays in another room, for example) rather than relying on in-the-moment willpower. Making the screen less available is easier than deciding not to use it every single evening.
If sleep difficulties feel entrenched – if winding down consistently feels impossible, or if you wake through the night despite a good routine – it could be worth speaking with someone who works in this area. Sleep coaches, therapists who use cognitive behavioural approaches for sleep, and acupuncturists all work with people exploring persistent sleep challenges. Your GP is also a valuable first conversation.
