Breathe away the nausea: new study tests nostril breathing for morning sickness
NCT ID NCT07378839
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a daily breathing exercise called alternate nostril breathing can reduce nausea and vomiting in early pregnancy. One hundred pregnant individuals in their first trimester will either practice the breathing technique three times a day for a week or receive standard care. Researchers will measure changes in symptom severity using a standard nausea score.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Alternate nostril breathing (a breathing exercise)
- What this could lead to
- If it works, this could offer a simple, drug-free way to manage nausea and vomiting in early pregnancy.
- What could go wrong
- This is a small, early-stage trial with no blinding, so results may be influenced by placebo effects. The breathing exercise may not reduce symptoms for everyone.
