Objective: To recognize the causality of environmental factors (i.e. temperature, humidity and sun exposure) on nutritional variables, specifically body water balance and water-seeking behaviour.
Design: Author perspective.
Setting: Global.
Participants: Not applicable.
Results: A free-standing code supplement is provided to facilitate investigators in accessing meteorological data for incorporation into analyses related to nutrition and hydration.
Conclusions: Analytical models related to human hydration should account for the environment de rigueur.
