Summary

This study looks at whether a breathing technique used by free divers can reduce symptoms of allergic rhinitis, like nasal congestion and sneezing. Thirty adults with persistent allergies will practice the 40-minute breathing sessions. Researchers will measure symptom scores, nasal airflow, and other markers to see if the training helps.

Active substance: free diving breathing training
What this could lead to: If it works, this could offer a simple, drug-free way to reduce nasal congestion and other allergy symptoms.
What could go wrong: This is a very small early study with only 30 people, so results may not apply widely. The breathing technique may be hard to do correctly or may not help everyone.
