Assessment of Initial Stay Time and Work‐Rest Scheduling Over Consecutive Moderate‐Intensity Workdays in Hot Environments in Young and Older Males and Females

Continuous work to IST was reduced during afternoon work following morning work but was restored the next morning across sex and age groups. When applied after IST, prescribed work-rest cycles effectively maintained core temperature near safety limits. These findings highlight the need to consider work timing and worker characteristics when planning work in hot environments.
