Climate Change Is Now Affecting the Nation’s Ability to Be Active.

The conversation about climate change is often framed around carbon, energy, buildings, transport and long-term environmental targets. All of those things matter.

But there is another part of the conversation that now needs far greater attention: climate change is beginning to affect people’s everyday opportunity to be active.

In recent days, parts of the UK have experienced extraordinary heat, with temperatures reaching 35.1°C in London, breaking the UK’s previous May temperature record. The UK Health Security Agency also issued amber and yellow heat-health alerts across England, warning of increased risk to vulnerable people during the hot weather.

For some, hot weather may still be seen as something to enjoy. A day in the park. A busy beach. A chance to get outside. But for many organisations working across sport, leisure, physical activity, education and community health, the impact is becoming much more serious.

Events are being cancelled. Outdoor sessions are being adapted or postponed. Children are being treated for heat-related injuries. Playgrounds, sports surfaces and public spaces are becoming too hot to use safely. In some cases, even something as simple as a child going down a playground slide has become a safeguarding concern. That should stop us in our tracks.

Because if we are serious about getting the nation active, we need to understand that climate change is no longer just an environmental challenge. It is a participation challenge. A health challenge. A safety challenge. And, increasingly, an inequality challenge.

The conditions for activity are changing.

For years, the sport and physical activity sector has rightly focused on removing barriers. Cost. Confidence. Transport. Time. Safety. Access to facilities. Lack of local provision. Cultural relevance. Disability inclusion. Poor health. Social isolation.

These barriers have not gone away.Climate change is now adding another layer.

When temperatures become unsafe, outdoor activity becomes harder to deliver. When parks offer limited shade, people stay away. When playground surfaces become dangerously hot, children lose safe opportunities to play. When walking routes lack trees, benches, water access or rest points, older adults and people with long-term health conditions may feel less able to leave the house. For families living in smaller homes, without gardens, air conditioning, access to private transport or the ability to travel to cooler places, the impact can be even greater.

The risk is that the people who already face the greatest barriers to being active are also the people most exposed to the effects of extreme heat and, that matters deeply.

Physical activity is not a luxury. It is part of how people stay well, manage stress, build confidence, connect with others, protect their independence and improve their long-term health. If climate change starts reducing access to everyday movement, then it will inevitably make existing health inequalities worse.

This is already affecting delivery.

Across the sector, professionals are beginning to see the practical consequences.

Community sessions are being moved indoors where possible. Youth sports are being cancelled or shortened. Coaches and volunteers are having to make difficult decisions about whether the activity is safe to continue. Schools and community organisations are adapting timetables, increasing rest breaks and checking surfaces before children play.

This is not simply an inconvenience. It affects trust, consistency and participation.

For many communities, regular activity depends on routine. A weekly session. A familiar coach. A trusted group. A safe place to go. When that routine is repeatedly disrupted by heat, flooding, poor air quality or unsafe conditions, participation becomes harder to sustain.

The sector is already working against a difficult backdrop. Inactivity remains too high. Health inequalities are stubborn. Public services are under pressure. Community organisations are stretched. Facilities are facing rising costs. Local authorities are balancing impossible budgets.

Climate change adds pressure to a system that is already carrying too much.

The danger is that we treat extreme weather as an occasional operational problem, rather than recognising it as a structural issue that will shape the future of participation.

We need to design for the climate we now live in.

If we want people to be active throughout their lives, we need places that support activity in changing conditions.

That means thinking differently about the design of schools, parks, streets, playgrounds, leisure facilities, sports clubs and community spaces. Shade can no longer be seen as a nice extra. It is part of safe participation. Trees, green space, water fountains, rest areas, safe walking routes, cooler indoor spaces and climate-resilient facilities are not separate from the physical activity agenda. They are part of it.

A park without shade may be unusable for some people during hot weather. A playground with surfaces that overheat may become unsafe. A walking route without rest points may exclude older adults, disabled people or those managing long-term health conditions. A community facility that cannot stay cool may struggle to protect the people who need it most.

The World Wide Fund for Nature and Learning Through Landscapes have already warned that school grounds can be vulnerable to extreme heat and flooding, with artificial surfaces becoming significantly hotter than natural surfaces during heatwaves.

This should matter to everyone working in sport, physical activity, education, public health, planning, regeneration and community development.

Because the places we build and maintain today will determine how active, healthy and resilient communities can be tomorrow.

Climate change is a public health issue.

The UK Health Security Agency’s Health Effects of Climate Change report highlights that climate change is making extreme weather events in the UK, including more frequent and intense heatwaves, more likely. That has direct consequences for health.

Heat affects the body. It increases risk for older adults, young children, people with long-term conditions, disabled people, pregnant women, outdoor workers and those living in poor-quality housing. It can worsen existing illness, increase pressure on health services and restrict people’s ability to take part in daily life.

But there is another consequence that receives less attention.

When heat makes it harder to move, play, walk, cycle, train, volunteer or take part in community activity, it also affects the preventative health agenda.

The country cannot afford for physical activity to become more difficult. We need more people moving more often, not fewer. We need children building positive relationships with play and movement. We need older adults staying strong, connected and independent. We need communities where activity is easy, safe, affordable and normal. Climate change threatens that unless we respond with urgency and imagination.

The sector has a vital role to play.

The sport, leisure and physical activity sector cannot solve climate change alone.

But it can play a major role in helping communities adapt. It can gather evidence from the front line. It can show how extreme weather is affecting participation. It can work with planners, public health teams, schools, local authorities, housing providers, transport teams and community organisations to design better local environments.

It can make the case that climate resilience is not just about protecting buildings. It is about protecting people’s ability to live healthy, active lives. This is where the conversation needs to move.

Sustainability should not sit in isolation from participation. Climate adaptation should not sit separately from health inequalities. Environmental planning should not be disconnected from public health.

This is where the climate conversation becomes very real. It is no longer about distant targets or abstract policy. It is about a child being unable to play safely because the equipment is too hot. It is about an older person deciding not to walk to the shops because the route offers no shade, no seating and no confidence that they can manage the journey. It is about coaches, volunteers and community organisations having to cancel activities because the conditions are no longer safe.

And, as is so often the case, the impact will not be felt equally. Communities with fewer trees, poorer housing, limited access to parks, less green space and fewer cool, welcoming places to gather will find it harder to stay active, connected and well. That is why climate change cannot sit on the edge of the physical activity conversation. It is already shaping who gets to move, who feels safe outside, and who has the greatest chance of living a healthy life.

A moment to think differently.

The recent heat should be a wake-up call. Not one based on panic, but one based on responsibility.

We need to ask better questions. Are our parks, playgrounds, sports facilities and community spaces ready for a hotter climate? Are we supporting coaches, teachers, volunteers and activity providers with the guidance they need? Are we designing places that allow people to be active safely in all conditions? Are we listening to the communities most affected? Are we treating climate resilience as part of public health?

The answers will shape the future of physical activity in this country.

For Why Sports, this is exactly why the relationship between sustainability, health and physical activity must become central to sector thinking.

Climate change is not something happening elsewhere. It is already affecting delivery, participation and safety in communities across the UK.

If we want a healthier, happier and more active nation, we must create environments that make movement possible, safe and enjoyable in the climate we now face.

The future of physical activity will not only depend on programmes, campaigns and participation targets. It will depend on whether the places around us are fit for the world we are living in.
