An app-based REHEAT intervention reduces adverse effects of heatwaves among Swiss home care workers
This protocol describes a randomized controlled trial testing the REHEAT app intervention to protect home care workers from heat-related health risks. The study involves 350 participants randomized 1:1 to intervention or control, with outcomes including strain accumulation, cognitive performance, emotional distress, sleep, night recovery, and mental and physical health. No outcome data have been analyzed yet as the study is ongoing.

Mechanism Graph
App provides strategies to reduce heat exposure during work
↓
Workers implement cooling behaviors and adjust work patterns
↓
Reduced physiological strain and improved recovery during night
↓
Result: Lower adverse health effects from heatwaves
Limitations
- ⚠Unblinded design may introduce bias
- ⚠No outcome data available yet; results are pending
