Hydration, Ergonomic Risk, and Fatigue Across Multiple PepsiCo Facilities

Physically demanding occupations require high levels of energy expenditure, mental sharpness, and technical skills, and are often performed in extreme environments during hot/humid summer months. Previous research shows dehydration and heat stress can increase risk of heat-related illness, reduce cognitive function, and work capacity. The relationship between hydration status and occupational physical and environmental demands has yet to be fully understood and compared across occupations. This study will examine hydration, sweat profile, activity level and its association with ergonomic risk (high, moderate, and mild risk movement patterns performed during work) and fatigue to improve our understanding of the hydration needs of warehouse workers.
