ACTUAL WORK STYLE AND ENVIRONMENT DURING OFFICE WORK AND WORK FROM HOME AND THEIR RELATIONSHIP WITH WORKERS’ SLEEPINESS

Abstract

This study investigated the differences between office work and work from home, using subjective indicators (questionnaires and diaries) and objective indicators (environment and biometric data from sensors). Results showed that workers experienced more morning sleepiness when working from home, despite sleeping longer hours, compared to when working in the office. This could be due to the lack of physical activity associated with commuting and lower illuminance at home compared to the office. Additionally, sleepiness increased in the afternoon during office workdays, implying that adjusting air conditioning based on time of day could help alleviate this issue.
