Effects of unilateral nostril breathing on blood pressure and heart rate in right-handed healthy subjects.

The effects of unilateral forced nostril breathing (UFNB) on systolic and diastolic blood pressures and heart rate (HR) were studied in 88 male and 41 female right-handed subjects.

In women, the right UFNB increased, but the left UFNB slightly decreased the SBP and DBP.
