Pranayamas and Their Neurophysiological Effects

Area of Science:

• Neuroscience
• Psychology
• Yoga Studies

Background:

• Yogic breathing exercises, known as Pranayamas, are ancient practices associated with meditation, stress reduction, and improved lung capacity.
• The precise physiological mechanisms through which these breathing techniques influence the human nervous system remain largely unexplored.

Purpose of the Study:

• To conduct a systematic review of existing literature on the effects of breathing exercises on human brain and cognitive function.
• To synthesize findings from studies investigating the mind-body connection through yogic breathing practices.

Main Methods:

• A comprehensive literature search was performed across major databases (Science Direct, PubMed, Virtual Health Library) for English-language articles published between 2008 and 2018.
• Study selection adhered to PRISMA guidelines, incorporating criteria for patient population, intervention, comparison, and outcome (PICO).
• A total of 1588 articles were initially identified, with 14 ultimately meeting the inclusion criteria for critical analysis.

Main Results:

• The reviewed studies consistently indicate that yogic breathing techniques positively influence emotional regulation and cognitive abilities.
• Key outcomes reported include enhanced emotional performance and improved cognitive functions across various studies.
• Data was systematically extracted and presented in a comparative table detailing study characteristics and outcomes.

Conclusions:

• The reviewed literature collectively supports the significant impact of yogic breathing techniques on emotional and cognitive performance.
• Further in-depth research is recommended to explore the specific effects of distinct yogic breathing components, such as breath retention and variations in respiratory patterns (abdominal/thoracic).
• Elucidating the effects of specific Yogic Breathing Techniques (YBT) components will provide a clearer understanding of their neurophysiological underpinnings.
