Hijab and heat: small study tests exercise risks for muslim women
NCT ID NCT07174180
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether wearing a hijab (headscarf and cloak) makes it harder for the body to cool down during exercise in hot, dry weather. Twelve healthy women aged 18-35 will exercise in a 40°C room, both with and without a hijab. Researchers will measure body temperature, heart rate, and how much heat the body loses through sweat and skin.
