What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
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.

Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled

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

Researchers at Fudan University are testing what happens to healthy young adults when they sit in a 32°C chamber for two hours. They will measure blood vessel stiffness, lung function, and mental speed, comparing these to a day spent at a comfortable 22°C. The study aims to reveal how a short heat exposure affects the body's systems, which could inform public health advice 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
high temperature (32°C) exposure in a chamber
What this could lead to
If it works, this could clarify how short heat waves strain the body, pointing to ways to protect people during hot weather.
What could go wrong
This is a small, early study in healthy young adults, so results may not apply to older people or those with health conditions. The brief heat exposure may not reflect real-world heat waves.

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.
