Singapore Study Shows Nature Play Boosts Emotional Regulation in Children with Autism

In a recent video report by CNA, the agency highlighted a three‑year study conducted in Singapore that examined the impact of nature‑based play on children with autism spectrum disorder (ASD). The research, carried out jointly by the National Parks Board (NParks), the National University of Singapore (NUS) and National University Hospital (NUH), tracked a cohort of 28 children and their caregivers over a six‑week intervention period, followed by a month‑long observation after the program concluded. The findings suggest that structured outdoor activities can enhance emotional regulation, communication and social interaction for children with ASD, and that these benefits may endure beyond the immediate intervention. This article analyses the study’s methodology, results and potential relevance for Japanese policy, healthcare and educational practice, while situating the work within broader regional trends toward nature‑based therapeutic approaches.

Study Design and Participant Profile

The Singapore study enrolled 28 children diagnosed with autism, together with their primary caregivers. Participants were recruited through clinical pathways at National University Hospital and through community outreach coordinated by NParks. Over the three‑year span, the research team conducted a series of six‑week nature‑play sessions, each consisting of regular, guided activities in natural settings such as parks, gardens and green corridors managed by NParks.

Each session was structured to incorporate sensory‑rich experiences—such as tactile interaction with soil, auditory exposure to birdsong, and visual engagement with foliage—while also embedding simple social tasks like turn‑taking, joint attention exercises and cooperative games. Caregivers were present throughout, enabling them to observe behavioural changes and to receive training on how to replicate similar activities at home.

Data collection combined quantitative measures, such as standardized behavioural checklists completed by caregivers, with qualitative observations recorded by the research team. Follow‑up assessments were conducted one month after the final session to gauge the persistence of any observed improvements.

Key Findings on Emotional Regulation

The video report emphasizes that children who participated in the nature‑play programme demonstrated a noticeable improvement in their ability to regulate emotions. Caregivers reported fewer instances of meltdowns and heightened capacity to self‑soothe when confronted with stressful stimuli. These observations align with prior research indicating that natural environments can modulate autonomic nervous system activity, thereby reducing physiological arousal.

Importantly, the study documented that the emotional benefits were not fleeting. One month after the six‑week programme ended, many participants continued to exhibit calmer responses and a reduced frequency of emotional outbursts. This suggests that the skills acquired during nature play may have been internalised, allowing children to apply them in varied contexts beyond the structured sessions.

From a policy perspective, the persistence of these effects underscores the potential for nature‑based interventions to serve as cost‑effective complements to conventional therapeutic modalities, such as speech‑language pathology and behavioural therapy, which often require intensive professional involvement.

Improvements in Communication and Social Interaction

Beyond emotional regulation, the study reported gains in communication and social engagement. Children showed increased eye contact, more frequent initiation of joint activities, and a greater willingness to interact with peers during the play sessions. Caregivers noted that these behaviours extended into home environments, with children more readily using words or gestures to express needs.

The researchers attribute these outcomes to the multimodal sensory input provided by natural settings, which can scaffold language development by offering concrete referents for conversation—such as naming different plant species or describing the sounds of insects. Moreover, the collaborative nature of many outdoor games encourages turn‑taking and shared attention, core components of social competence.

For Japanese educators and therapists, these findings may inform the design of inclusive classroom activities that integrate green spaces, whether on school grounds or through partnerships with local parks. Given Japan’s emphasis on holistic education and the Ministry of Education, Culture, Sports, Science and Technology’s (MEXT) recent guidelines encouraging outdoor learning, the Singapore evidence provides a data‑driven rationale for expanding such practices to support children with ASD.

Toolkit Development and Practical Implementation

One of the study’s tangible outputs is a toolkit created jointly by NParks, NUS and NUH. The toolkit offers step‑by‑step guidance for parents, caregivers and therapists to incorporate nature‑based play into daily routines. It includes activity templates, safety checklists, and suggestions for adapting exercises to various age groups and ability levels.

NParks is actively exploring ways to disseminate the toolkit more broadly, including training workshops for community volunteers and collaborations with schools. The agency’s involvement reflects a growing recognition within Singapore’s public sector that parks and green infrastructure can serve therapeutic as well as recreational functions.

In Japan, similar cross‑sector collaborations could be fostered between municipal park departments, university research centres and healthcare providers. The Ministry of Health, Labour and Welfare (MHLW) has previously supported community‑based health promotion programmes; integrating nature‑play resources could complement existing initiatives aimed at early childhood development and disability support.

Implications for Japanese Healthcare and Social Services

The Singapore study’s outcomes have relevance for Japan’s ageing and declining birth‑rate context, where the government seeks innovative, low‑cost interventions to support vulnerable populations. While the study focused on children, the underlying principle—that natural environments can mitigate stress and enhance social functioning—has been observed in elder care settings as well. This suggests a potential for a unified policy approach that leverages green spaces across the lifespan.

From a fiscal standpoint, the nature‑play model could reduce reliance on high‑intensity clinical services. If replicated, the programme might lower the frequency of hospital visits for behavioural crises, thereby easing pressure on the national health insurance system overseen by the Ministry of Health, Labour and Welfare. Moreover, the toolkit’s emphasis on caregiver empowerment aligns with Japan’s broader strategy to support family‑based care, a cornerstone of its long‑term care policy.

Future research collaborations between Japanese universities—such as the University of Tokyo’s Institute of Social and Environmental Sciences—and Singaporean partners could validate the toolkit’s efficacy within Japanese cultural and environmental contexts. Such joint studies would also enable the adaptation of activity content to local flora and seasonal variations, ensuring relevance and sustainability.

Regional Trends and Future Directions

The CNA report situates the Singapore findings within a growing regional interest in nature‑based therapeutic interventions. Countries across Southeast Asia and the Pacific are increasingly recognising the mental health benefits of green spaces, especially in urban environments where children spend limited time outdoors. Singapore’s proactive stance, exemplified by NParks’ involvement, signals a policy shift toward integrating environmental design with health outcomes.

For Japan, which boasts an extensive network of public parks, forests and riverbanks, the opportunity to embed therapeutic programming into existing infrastructure is considerable. The Ministry of Land, Infrastructure, Transport and Tourism (MLIT) could coordinate with local governments to designate specific zones for nature‑play activities, ensuring accessibility for families with children with ASD.

Looking ahead, the durability of the Singapore study’s effects—evident a month after the intervention—suggests that periodic reinforcement, perhaps through seasonal nature‑play camps or school‑based outdoor curricula, could sustain and deepen benefits. Monitoring and evaluation frameworks, possibly overseen by the Cabinet Office’s Office for the Promotion of Innovation, would be essential to track outcomes and refine programme design.
