What this trial studies

This study aims to explore the factors contributing to personal heat stress during warm periods in urban settings, particularly focusing on the Ile-de-France region. It will assess outdoor environmental conditions, building characteristics, and individual behaviors to understand their impact on heat stress. Participants will be monitored over two periods, with data collected through smartphone tracking and detailed assessments of their living environments. The study seeks to correlate heat stress with physiological indicators and overall well-being.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 30-64 living in the Ile-de-France region.

Not a fit: Patients with significant mobility limitations, certain cardiovascular conditions, or those unable to participate in follow-up assessments may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into mitigating heat stress and improving health outcomes for individuals living in urban heat islands.

How similar studies have performed: While studies on heat stress and urban environments exist, this approach utilizing mobile sensing technology for detailed assessments is relatively novel.
