Research Mission

The overall research program of the Water and Health Lab is designed to understand cross-cultural variation in how humans meet their water needs and how this relates to perception, environmental resources, water insecurity, and health, hydration, and disease risk. It examines how humans respond through behaviors to changing nutritional, physical, and economic environments through water and dietary intake and the significance of mismatches in these relationships for short- and long-term health, nutrition, and disease. In particular, these issues are explored in the Bolivian Amazon among indigenous Tsimane’ forager-horticulturalists, in Kenya among Daasanach agro-pastoralists, and in the US using complex survey data from the National Health and Nutrition Examination Surveys (NHANES). In addition, the lab is part of the Household Water Insecurity Experiences Scale (HWISE) consortium aimed at cross-culturally validating a water insecurity scale.

The Water and Health Lab integrates biological, nutritional, environmental, quantitative, and ethnographic methods to explore the consequences of these strategies, states of health and behaviors, and of different diseases on hydration status.

  • Hydration status projects
  • Water insecurity and links to health outcomes, stress, disease, and hydration
  • Exploration of trust related to tap water
  • Use of biomarkers in field studies
