An app-based intervention (REHEAT strategy) 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 aims to evaluate the effectiveness of the app in reducing strain accumulation, improving cognitive performance, emotional distress, sleep, night recovery, and mental and physical health during summer months. The trial involves 350 participants from Northern and Southern Switzerland, with data collection ongoing and no results yet available.

The Claim
An app-based intervention (REHEAT strategy) reduces adverse effects of heatwaves among Swiss home care workers
This conclusion is most relevant to: Swiss home care workers (n=350) from Northern and Southern Switzerland.
What the Research Shows
The conclusion draws on 1 linked study. Highlights from the cited literature:
- ▸An App-Based Intervention to Protect Home Care Workers From Heat-Related Health Risks: Protocol for a Randomized Controlled Trial. (Inquiry : a journal of medical care organization, provision and financing, 2025) —
How It Works
The proposed biological pathway:
- ▸App provides real-time heat risk alerts and guidance
- ▸Workers modify behavior to reduce heat exposure
- ▸Reduced physiological strain and improved recovery
- ▸Result: Lower adverse health effects during heatwaves
Who Might Benefit
Evidence fit by population:
- ▸Swiss home care workers (n=350) from Northern and Southern Switzerland
Recommended Dose
N/A
Limitations & Caveats
Important context when interpreting this evidence:
- ▸Unblinded design may introduce bias
- ▸No outcome data yet available; results are pending
- ▸App usage compliance may vary and affect real-world effectiveness
