Tim began his journey into holistic health through a transformative project in Singapore’s Queenstown Health District, where he explored health from a broader perspective, considering not just physical well-being but also mental, emotional, and spiritual aspects. This project sparked a profound shift in his perspective, prompting him to move beyond conventional health systems and delve into the broader aspects of life and community that influence well-being. His exploration led him to recognise the critical impact of Social Determinants of Health (SDH)—non-medical factors that significantly shape health outcomes. 

“About five years ago, I encountered the SDH, which, while not new, completely halted me,” Tim reflects. “There’s a well-known chart indicating that only 10% of an individual’s health is determined by the quality of healthcare they receive. Genetic factors make up about 30%, beyond our control. However, the majority of health determinants are social and environmental. This realisation was truly eye-opening for me.” 

Through the Queenstown project, Tim learned firsthand the vital role of co-design in healthcare. He stresses that healthcare providers and policymakers often assume they know what communities need based on research and expertise, potentially leading to ineffective solutions. “We may believe we have all the answers for citizens and patients, but we don’t. This explains why some interventions fall short—they lack genuine community input.” 

Tim stresses that co-design must be integral throughout the process to ensure programme effectiveness and responsiveness to community needs. “Listening is a challenging skill,” Tim acknowledges. “Sometimes, we listen merely to affirm our own viewpoints. True listening involves embracing diverse perspectives and being willing to adapt. Humility and readiness to change come with genuine listening.” 

A memorable conversation with an older woman about dietary changes highlighted the gap that arises when public health messages lack cultural sensitivity. “She was advised that all her traditional foods were detrimental to her diabetes, which left her confused and at a loss. This reinforces the importance of connecting on a personal and cultural levels to truly make a difference.” 

Tim applauds Singapore’s shift towards preventive healthcare measures, marking a positive evolution from a reactive to a proactive approach. “For the past three decades, healthcare primarily focused on treating diseases when patients were already in critical condition. Now, the emphasis is on prevention, requiring a mindset shift and collaboration across sectors to enhance efficacy.” 

Looking ahead, Tim advocates for co-design to take precedence in health interventions, citing platforms like our very own Voice that empower individuals by amplifying collective voices to influence policy and programs for better health outcomes. “Many people feel their voices are insignificant, but platforms like Voice, which we are bringing to Singapore can ensure that together these voices to drive meaningful change.” 

Reflecting on Singapore’s strengths, Tim praises its robust public policy design, particularly in housing, which significantly impacts health outcomes. “Housing plays a pivotal role as a social determinant of health. Initially focused on practical mass housing, Singapore’s public housing has evolved to incorporate green spaces, environmental sustainability, and wellness elements, supporting long-term health and well-being.” 

Tim’s ultimate aspiration is for the wisdom of older generations to guide younger ones towards healthier lifestyles from an early age. “We often learn valuable lessons too late, after confronting health challenges. Embedding this wisdom in everyday environments—schools, social media, parks—could foster healthier habits early on.” 

Tim’s journey reinforces the imperative of a holistic health approach that integrates social and environmental factors, genuine community engagement through co-design, and culturally sensitive public health strategies. Through listening, collaboration, and empowering individuals, we can forge healthier communities and more effective health interventions. 

From Singapore’s innovative approach to healthcare and community well-being to exploring how cultural sensitivity shapes effective public health strategies—these questions ignite new perspectives and opportunities for enhancing global health and well-being and are at the heart of our global Voice community to explore with changemakers like Tim around the world.
