Picture a typical school day for a British child in 2025: a morning alarm followed by a scroll through a phone, a car journey to school, six or seven hours in a classroom, another car journey home, and an evening in front of a screen before bed. Caroline Voaden, the Liberal Democrat MP for South Devon, has a blunt question about this routine: “Is there any wonder they’re climbing the walls?” It is a vivid encapsulation of a problem that the data are now making impossible to ignore, and it has prompted her to table legislation that would, for the first time, make outdoor time a statutory requirement of the school day.
The scale of the crisis lends her argument considerable weight. The Royal College of Paediatrics and Child Health has found that the number of six to seventeen-year-olds presenting at accident and emergency departments in significant distress — for self-harm, eating disorders, or acute emotional crisis — rose by 36 per cent between 2019 and 2025. Children as young as six are now arriving at A&E units in mental health emergencies, a development that would have seemed extraordinary a generation ago and which no serious policymaker can now dismiss. Against this backdrop, the search for cost-effective, scalable interventions has acquired a genuine urgency, and it is here that Voaden’s proposal finds its most persuasive footing.
Her Outdoor Education Bill is, in its essentials, a straightforward piece of policy. It would require all children in primary and secondary education to spend a minimum of thirty minutes a day outdoors during school hours, mandate at least one lesson per week conducted outside the classroom, and ensure that every pupil receives at least one residential outdoor education experience during both their primary and secondary years. The mechanisms are simple; the costs, relative to other mental health interventions, are modest; and the evidence base linking time in natural environments to reduced stress, improved mood, and stronger immune function is well established. What has been lacking, Voaden argues, is not evidence but political will.
The barriers she identifies are real and worth taking seriously. Expensive parking, inadequate public transport, and a shortage of accessible green or blue spaces conspire to keep children — particularly those from deprived communities — indoors. She notes, with visible frustration, that some youngsters living less than a mile from the Devon coastline have never set foot on a beach, a circumstance she describes as “tragic.” Urban children are not without options, she concedes, pointing to parks and green corridors as meaningful substitutes, but the structural inequalities of access remain a legitimate policy concern that the Bill alone would not resolve. Mandating outdoor time at school, however, would at least guarantee a baseline that does not depend on parental income or geography.
Voaden’s advocacy is informed by personal experience of a kind that gives it a texture beyond the merely political. Her husband Nick died in 2003 at the age of forty-two from terminal oesophageal cancer, leaving her a widow at thirty-four with daughters aged seventeen months and three years. Her decision to leave London for Devon was, she explains, driven by a deep-seated conviction that proximity to the natural world would ease the weight of grief — not a calculation, but an instinct. “Going for a long walk or going for a swim in the sea,” she says, “is really, really good for my mental health.” Her daughters, now adults, have internalised the same reflex: when stressed, they go to the beach, or, if they are in London, they walk around the park. The habit, cultivated in childhood, has become a durable coping mechanism — which is precisely the outcome she wants to replicate for children who have never had the opportunity to form it.
There is also a pedagogical argument embedded in the Bill that deserves attention on its own terms. Voaden contends that children who struggle within the conventional classroom may flourish in outdoor settings, and that subjects including English, history, and mathematics can be taught effectively outside. More broadly, she argues that residential experiences — climbing a mountain, navigating unfamiliar terrain — build the kind of resilience that transfers back into academic life. “They get back from the residential and they face a challenge in the classroom,” she says, “and they think: well, maybe I can do that, because I did get to the top of that mountain.” The confidence acquired outdoors, in other words, is not compartmentalised; it compounds. The obstacle, she believes, lies less with pupils than with teachers and school leaders who have never themselves experienced outdoor education and therefore lack the confidence to deliver it.
In the Commons, Education Secretary Lucy Powell offered a response that was warm in sentiment if carefully non-committal in substance, observing that the question of outdoor time “goes wider than the school system” and reflects broader questions about what childhood should mean in the twenty-first century. It was the kind of answer that acknowledges a problem without accepting responsibility for solving it — and it is precisely the sort of institutional hesitation that Voaden’s Bill is designed to overcome. Whether the Government ultimately adopts it will depend, as so often, less on the quality of the evidence than on the appetite for a clear, enforceable standard. The children arriving in A&E in emotional crisis might reasonably hope that appetite exists.
