What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

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.
