Deep Breathing Techniques (Pranayama) in Pregnancy
The Acute Effects of Pranayama (Deep Breathing Techniques) on Physiological Parameters in Pregnancy
Source: ClinicalTrials.gov · Last updated 20 Apr 2025
Brief summary (registry, in English)
Slow deep breathing actives the vagal nerve and leads to a natural reduction in physiological parameters such as blood pressure, heart rate and digestion. The effects of these techniques have not been assessed in pregnancy. The primary objective is to assess the effects of various yogic deep breathing techniques on blood pressure during pregnancy. The breathing exercises will include Alternate nostril breathing, Bhramari breathing, and Sheetali breathing. A secondary objective will be to assess the effects of these breathing exercises on other physiological parameters including heart rate, heart rate variability, body temperature, cardiac output, vascular resistance and respiratory rate.
