Summary
This study tested how well the hDrop wearable sensor measures sweat rate and sodium loss compared to standard lab methods. Twenty healthy adults wore the sensor while exercising in a hot room for 60 minutes. Researchers also collected sweat using patches and electrical stimulation to check the device's accuracy and reliability across two separate visits.

- Active substance
- hDrop hydration sensor
- What this could lead to
- If the hDrop sensor proves accurate, it could offer a simple way for athletes and workers to monitor hydration and electrolyte loss in real time.
