Study Finds Physical Workload Increases During Ramadan

A research article published in the Institute of Occupational Health and Safety (ISST) journal, January 2026.

Overview

A team of occupational physicians at Fattouma Bourguiba University Hospital in Monastir carried out a study on the impact of non‑conventional work schedules and the associated medical monitoring requirements during the holy month of Ramadan. The investigation revealed that physical work demands are significantly higher throughout this period.

Key Findings

Work classified as more strenuous during Ramadan, driven by:
- Adverse working conditions.
- Alterations in eating habits (shifted meal times and fasting).
- Increased sleep disturbances.
Functional disorders linked to the changed meal schedule and fasting, especially digestive issues.
Sleep deprivation was prevalent:
- 66 participants reported sleeping less than six hours per night during Ramadan.
The lack of sleep emerged as a hardship factor, contributing to a rise in cardiac fatigue associated with work performed in the fasting month.

Implications

The study underscores the need for adjusted occupational health policies during Ramadan, such as:

Flexible scheduling to accommodate altered energy levels.
Enhanced medical monitoring for early detection of fatigue‑related conditions.
Nutritional guidance to mitigate digestive disturbances.
Sleep‑health interventions (e.g., nap opportunities, education on sleep hygiene).
