Summary

This study looked at whether slow, deep breathing for 10 minutes daily could help lower blood pressure in pregnant women with pregnancy-induced hypertension. Only 1 participant was enrolled before the study was terminated, so no meaningful conclusions can be drawn. The goal was to see if a larger trial would be practical.

What this could mean

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

Active substance
slow and deep breathing exercise
What this could lead to
If it works, this could offer a simple, drug-free way to help manage blood pressure during pregnancy.
What could go wrong
The study was terminated after enrolling only 1 person, so there is almost no data to support effectiveness. It is a very early feasibility trial, not a large or conclusive study.
