This document summarizes a study on indigenous knowledge for health management during flood disasters in central Thailand communities. The study explored indigenous knowledge on health management during floods through interviews with 291 people in Ayutthaya Village. It identified key indigenous practices for food preparation, exercise, health protection, sanitation, and stress management during floods. The results were used to develop a three-stage health management model for floods: preparation, disaster response, and post-disaster recovery. The model aims to help villagers effectively deal with health issues during floods using their cultural knowledge and practices.
