Bubbly water may keep you from fainting
NCT ID NCT05621460
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether carbonated water can help people stay steady on their feet and avoid fainting. Drinking water is known to raise blood pressure, but researchers want to see if the bubbles in carbonated water add an extra benefit by stretching the stomach. 25 healthy adults will be tested to compare the effects of carbonated versus still water.
