Journaling as a mindfulness tool: how to start

Sales of paper journals at Waterstones' flagship Piccadilly branch rose 22 percent in the first half of 2026, according to figures shared by the retailer last month. That number cuts against the narrative that mindfulness is purely a digital-first industry. It also points to something therapists and GPs across the capital have been quietly noting for the past two years: journaling is back, and this time it is arriving with a growing evidence base behind it.

The timing matters. NHS mental health waiting lists in London boroughs including Southwark and Tower Hamlets still stretch beyond 18 weeks for talking therapies as of this spring. With access to professional support constrained, clinicians at practices including the Bromley-by-Bow Centre in East London have been encouraging patients toward structured self-reflection as a bridging tool — something substantive to do with anxiety and low mood while they wait. Journaling fits that gap almost exactly.

What the evidence actually shows

A 2024 study published in the Journal of Experimental Psychology found that participants who wrote expressively about stressful events for 20 minutes on three consecutive days reported significantly lower anxiety scores at a four-week follow-up compared with a control group. The effect size was modest but consistent — and the intervention cost nothing. Researchers at University College London's Clinical Psychology programme have pointed to similar findings in work on cognitive defusion, the process of creating distance between a person and their intrusive thoughts by externalising them onto a page.

The NHS's own Every Mind Matters platform, relaunched with new content in January 2026, now lists journaling under its self-care recommendations alongside sleep hygiene and physical activity. It is a small but telling shift from an organisation that has historically been cautious about endorsing practices without robust trial data.

Prices for commercial mindfulness apps, meanwhile, have climbed sharply. A Calm annual subscription now costs £59.99, and Headspace sits at £49.99 a year. A decent Leuchtturm1917 notebook — favoured by many journal keepers for its numbered pages and index — retails at around £18 at the London Graphic Centre on Long Acre in Covent Garden. The arithmetic is not complicated.

Getting started without overcomplicating it

The biggest obstacle most beginners describe is the blank page. Therapists working with community groups at the Bethlem Royal Hospital in Beckenham, which houses one of the UK's longest-running mental health research centres, often suggest starting with a single sentence — not a topic, just a sentence about whatever is physically present. What you can see. What your body feels like. The temperature of the room. It sounds trivially simple. That is the point.

Three formats have accumulated the most evidence for general wellbeing. Free writing — unedited, unfiltered, for a set number of minutes — targets emotional processing. Gratitude journaling, which involves noting three specific things that went well on a given day, has shown particular promise in studies focused on low-level persistent stress. Structured prompts, popular in guided journals sold at shops like Paperchase's Tottenham Court Road store, work well for people who find open-ended writing paralysing.

Consistency matters more than duration. Ten minutes at the same time each day — many practitioners attach it to an existing habit like a morning coffee or the Overground commute from Hackney Central to Highbury — appears to outperform sporadic longer sessions. The Royal Parks running network, Parkrun events at Bushy Park in Richmond every Saturday morning, and the expanding cycling superhighways along the Embankment all have one thing in common: they work as mindfulness practices precisely because they are habitual and low-friction. Journaling operates on the same principle.

If you are carrying significant anxiety, depression or trauma, journaling is a complement to professional support, not a substitute. Your NHS GP is the right first call. But for the everyday accumulation of stress that most Londoners carry through working weeks in this city, ten minutes and a pen may be the most underrated tool available — and the one that requires no Wi-Fi, no subscription, and no waiting list.
