Changes in Hydration Status of PepsiCo Frontline Workers in a Manufacturing Facility Over the Course of Multiple Shifts

PepsiCo Global R&D30 enrolled

Overview

Physically demanding occupations (PDO) require high levels of energy expenditure, mental acuity, and technical skills. Sometimes this work is performed in extreme environments during hot/humid summer months. Previous research shows that dehydration and heat stress can increase risk of heat-related illness, reduced cognitive function, and work capacity. While this impact of physically demanding work in extreme environmental conditions is often studied in firefighters, military personnel, and athletes, and even agricultural workers, manufacturing and warehouse workers ("the industrial athlete") are underrepresented in the literature. The purpose of the study is to examine the impact hydration status of the industrial athlete (i.e., frontline manufacturing and warehouse workers at PepsiCo facilities) prior to, during, and after their shift over a typical work week has on work performance. Note: Recruitment is limited to PepsiCo Frontline Employees Only. Do not contact study official for enrollment.
