Abstract in brief

Water is crucial for survival, yet 2.2 billion people lack access to safe drinking water globally.
A study of 5,604 individuals across 23 countries examined various factors affecting water turnover (WT), revealing that age, body size, physical activity, and socioeconomic status all play significant roles.
The research also found that people in countries with low human development indices have higher WT, and it provides equations to help predict WT based on different personal and environmental factors.
