Do I need a digital detox?

Francis Merson Clinical Psychologist

Digital detoxes have become a popular wellness trend, framed as a way to reclaim focus and mental clarity. Public figures such as Arianna Huffington and Cal Newport have argued that constant connectivity erodes attention and sleep, and while former Google design ethicist Tristan Harris has warned about the addictive architecture of digital platforms. The idea of periodically disconnecting has thus moved from fringe self help into mainstream conversation.

So what exactly is a digital detox? A digital detox usually refers to a defined period of limited or eliminated use of smartphones, social media or screens more broadly. For some, this means deleting social apps for a week. For others, it means no phone after 8 pm or a screen-free weekend. Proponents often frame it as a way to “reset dopamine”, restore attention and reverse the effects of constant stimulation. The idea is that stepping away from rapid, unpredictable digital rewards allows the brain’s motivation system to recalibrate and makes slower activities feel rewarding again.

What is the rationale for a detox?

The rationale draws from behavioural psychology and neuroscience. Digital platforms are built around variable rewards. You do not know when the next interesting post or message will appear. Research on reinforcement learning shows that unpredictable rewards are especially powerful in shaping behaviour, which is why similar principles are used in gambling design, on devices like slot machines.

Unpredictable rewards trigger anticipation, which releases dopamine and reinforces checking behaviour, creating a feedback loop.

Dopamine plays a central role here. It is not simply a pleasure chemical but a signal of anticipation and motivation. When rewards are uncertain, dopamine activity increases. Over time, this can train attention towards novelty, interruption and rapid feedback.

Advocates argue that frequent exposure to these reward patterns fragments attention, reduces boredom tolerance and increases stress. A detox, in theory, interrupts this cycle.

Is there hard evidence that they work?

The evidence is mixed but not empty. Experimental studies in which participants reduced or stopped social media use for short periods, often one to four weeks, have shown modest improvements in mood, reduced anxiety and better sleep for some individuals. Effects tend to be stronger in heavier users and in those who were already distressed.

However, there is little evidence for dramatic “dopamine resets”. The brain’s reward system is adaptive, not easily damaged by normal technology use. Improvements seen in studies are more plausibly explained by reduced social comparison, fewer interruptions and lower cognitive load rather than a neurochemical overhaul.

"Changing the environment around you generally works better than relying on willpower"

It makes sense theoretically that reducing interruptions would improve concentration and that limiting emotionally charged content would reduce stress. What is less supported is the idea that a short abstinence period fundamentally rewires the brain.

So if my smartphone use is a problem, what techniques might actually work? Research on attention and behaviour change suggests that small structural adjustments are more effective than dramatic bans.

Simple changes that have been shown to be effective are:

• keeping your phone out of the bedroom

• setting defined times for answering emails

• removing high-pull apps like TikTok and Instagram from the home screen

• keeping one screen-free evening per week
  

Studies on task switching show that frequent interruptions between tasks impair performance and increase perceived stress. The human brain seems to be happier focusing on only one thing, and for a reasonable length of time. Interventions that protect uninterrupted blocks of time can reliably improve both productivity and subjective calm. And it seems that changing the environment often works better than relying on willpower.

For those who feel ashamed of their smartphone use, it's important to remember that these patterns are caused by the hijacking of your nervous system by external devices, not a moral failure on your part. Your brain is simply doing what it has been trained to do.

Are we even asking the right question here?

A deeper question is not whether you need a digital detox but what your phone is doing for you psychologically. Are you using it to regulate boredom, loneliness or anxiety? Do you feel wired and depleted after scrolling, or connected and informed? Is your use intentional or automatic?

For many people, the device functions as a rapid mood regulator. It fills silence, softens loneliness, distracts from self doubt and provides stimulation on demand. When you reduce it, the discomfort it was masking can become more visible. That discomfort is usually where the real work begins.

Most people do not need a dramatic detox. They need a more deliberate relationship with their attention. Because attention is not just about focus. It is about choosing how you spend your life, moment by moment.

What a detox really means

A digital detox does not have to mean deleting everything and disappearing for a week. Research on behaviour change consistently shows that smaller, clearly defined adjustments are more sustainable than dramatic bans.

Simple changes that have been shown to be effective are:

• keeping your phone out of the bedroom

• setting defined times for answering emails

• removing high-pull apps like TikTok and Instagram from the home screen

• keeping one screen-free evening per week

Making these small adjustments can meaningfully alter your attentional environment. In studies where participants reduced smartphone use for short periods, many reported improvements in mood, sleep and concentration, though effects do vary between individuals.

The key variable appears to be intentionality. When you choose how and when to engage, dopamine works for you rather than against you.

A better question to ask yourself...

Instead of asking whether you need a digital detox, it may be more useful to ask what role your phone is playing in your emotional life. Are you using it to avoid boredom, loneliness, anxiety or fatigue? When does it genuinely connect you? When does it leave you depleted? Technology amplifies existing tendencies. It rarely creates them from nothing.

If your phone use feels compulsive, interferes with work or relationships or is closely tied to low mood, anxiety or burnout, the issue may not be screen time alone. A digital reset can create breathing space. But often the deeper work involves stress, identity, belonging or emotional strain that the phone has been quietly regulating.

For many people, the device functions as a rapid mood regulator. It fills silence, softens loneliness, distracts from self doubt and provides stimulation on demand. When you reduce it, the discomfort it was masking can become more visible. The moment you confront that discomfort is often the moment that the real work begins.

A digital reset is not about rejecting technology. It is about deciding, deliberately, what deserves your finite cognitive and emotional bandwidth.
