Official title
The Effect of Wearing the Hijab on Dry and Evaporative Heat Exchange During Moderate-intensity Exercise Performed in Hot-dry Environments
Overview
The hijab (headscarf and cloak) is a Muslim dress, which covers the head, neck and chest, and conceals the female hair, leaving the face uncovered. It is worn by Muslim women worldwide including young Muslim women engaging in sports and exercise. As with any clothing worn on the body, the hijab can impact heat dissipation during exercise, potentially leading to increased body temperature and discomfort, especially in warmer environments. However, the extent to which the hijab may restrict heat loss remains unclear. This study aims to assess dry and evaporative heat exchange in young women performing moderate-intensity intermittent exercise in dry heat conditions (40°C, 15% relative humidity).
Interventions
- Other Exercise-heat stress with no hijab
Participants perform exercise in the heat with no hijab - Other Exercise-heat stress with a hijab
Participants perform exercise in the heat with a hijab
Primary outcome measures

- Total heat loss at end exercise [Time frame: End of the 60-min intermittent exercise bout]
- Body heat storage [Time frame: End of the 60-min intermittent exercise bout]
- Change in body heat content [Time frame: End of the 60-min intermittent exercise bout]
- Core temperature [Time frame: End of the 60-min intermittent exercise bout]
