Mauli ola, optimal health and wellbeing from a Hawaiian perspective, is achieved by being pono, or morally just and upright, and maintaining an intricate balance physically, mentally, spiritually, and emotionally through one’s relations. Cultural practices, including practices that foster a connection to the water, land, ocean, and natural environment, may serve as protective and resilience factors, thereby promoting health and wellbeing. This paper starts by sharing the genealogical foundations of cultural practices in Hawai‘i as the foundations of Native Hawaiian lifestyles and ways of knowing. The paper proceeds with data analyses that aim to better understand the role of cultural practices in relation to connectedness to ‘Āina (the land, nature, and the environment, which nourish our bodies) and Native Hawaiian health based on cross-sectional correlations and qualitative data. The findings demonstrate the importance of cultural practices, specifically ‘Āina practices, and identify ‘Āina protection, restoration, and conservation as major health priorities. The correlations demonstrate statistically significant relationships between cultural practices; a physical, mental, spiritual, and emotional connection to ‘Āina; and health outcomes. These findings continue to support literature and other declarations that support healthcare and medicine that are culturally grounded in Indigenous values and traditional systems of medicine.
