Summary

This study tests a device called VCool that is placed in the nose to cool the body. Ten healthy adults aged 18 to 55 will try it to see if it safely lowers core body temperature to about 35.5°C and keeps it there for an hour. The goal is to gather early data on how well it works and any side effects like shivering.

What this could mean

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

Active substance
VCool Intranasal Cooling System (device)
What this could lead to
If it works, this could point toward a non-invasive way to cool the body for medical emergencies like stroke or fever.
What could go wrong
This is a very early feasibility study with only 10 healthy volunteers. It may not work as expected or cause discomfort like shivering.
