The work-recovery cycle of kidney strain and inflammation in sugarcane workers following repeat heat exposure at work and at home.

Purpose: To examine heat exposure at work and home and the work-recovery cycle and temporal variation of kidney strain, muscle injury and inflammation biomarkers in sugarcane workers.

Methods: 20 male sugarcane workers (age: 33 ± 7 years) with a workplace Rest.Shade.

Targeting workload to ameliorate risk of heat stress in industrial sugarcane workers.

Objective: The aim of this study was to quantify the physiological workload of manual laborers in industrial sugarcane and assess the effect of receiving a rest, shade, and hydration intervention to reduce heat stress exposure risk.

Methods: In an observational study, physiological workload was evaluated for burned cane cutters (BCC), seed cutters (SC) and drip irrigation repair workers (DIRW) using heart rate (HR) recorded continuously (Polar®) across a work shift. Workers' percentage of maximal HR (%HR), time spent in different HR zones, and estimated core temperature (ECTemp) were calculated.
