Abstract

Academic performance is significantly influenced by indoor thermal conditions, where discomfort can disrupt learning processes and reduce productivity. This study examines an often-overlooked factor in thermal comfort research: the Islamic practice of ablution (wudu) and its duration-dependent effects on students' thermal perception.
The research employed a controlled climate chamber experiment simulating classroom conditions at four temperature levels (17°, 21°, 25°, and 29°C). Twenty male architecture students participated in a within-subject design, testing two conditions on consecutive days: with and without pre-session ablution. Thermal comfort was measured at 30-minute intervals over a 2-hour period using standardized assessments, with data analyzed via SPSS27.
Key findings reveal that ablution significantly extends thermal comfort tolerance. Participants who performed ablution maintained comfort for approximately 1.5 hours longer than their non-ablution counterparts across all temperature conditions. This effect was particularly pronounced in warmer environments (25-29°C), suggesting ablution's cooling mechanism—through evaporative heat loss from moistened skin surfaces—effectively buffers against thermal stress.
The study highlights the cultural dimension of thermal adaptation strategies, demonstrating how ritual practices can functionally interact with environmental physiology. These results offer practical implications for designing academic spaces in Islamic contexts, suggesting scheduling considerations for post-prayer classes and the potential integration of water-based cooling strategies in educational architecture. Further research should explore gender-specific responses and longer-term adaptation effects.
