Can wearable sensors unlock the hidden health toll of heat waves?

NCT ID NCT06850025

First seen Jul 31, 2026 · Last updated Jul 31, 2026

Summary

This study uses wearable sensors to track how heat exposure during daily activities affects the body, sleep, and wellbeing in 180 adults aged 30-64 living in the Ile-de-France region. Participants wear bracelets that measure skin temperature, blood pressure, and movement, along with sensors to gauge personal heat stress. The goal is to understand which environmental and behavioral factors contribute to heat stress and how that stress impacts sleep and overall health. The findings could inform strategies to protect people during hot weather.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Wearable sensors and mobile sensing technology to measure heat stress, sleep, and wellbeing
What this could lead to
If successful, this could reveal how heat exposure in daily life affects health and sleep, potentially guiding urban design and public health advice to reduce heat-related harm.
What could go wrong
This is an observational study, so it cannot prove cause and effect. Results may be limited by the specific region and participant group, and personal factors could influence the measurements.
