Positive emotion reduces dyspnea during slow paced breathing.
Slow breathing is used to induce cardiovascular resonance, a state associated with health benefits, but it can also increase tidal volume and associated dyspnea (respiratory discomfort). Dyspnea may be decreased by induced positive affect. In this study, 71 subjects (36 men, M = 20 years) breathed at 6 breaths per min. In condition one, subjects paced their breathing by inhaling and exhaling as...
متن کاملClinical utility of paced breathing as a concentration meditation practice.
OBJECTIVES The present study examined changes in electroencephalogram (EEG) and heart rate variability (HRV) parameters during paced breathing (PB) and their relationships with self-reported personality traits. METHODS Fifty-eight meditation-naive subjects (36 men, 22 women) ranging in age from 20 to 30 years completed the Temperament and Character Inventory (TCI). After a spontaneous breathi...
متن کاملCoherent Hemodynamics Spectroscopy Based on a Paced Breathing Paradigm — Revisited
A novel hemodynamic model has been recently introduced, which provides analytical relationships between the changes in cerebral blood volume (CBV), cerebral blood °ow (CBF), and cerebral metabolic rate of oxygen (CMRO2), and associated changes in the tissue concentrations of oxyand deoxy-hemoglobin ( O and D) measured with near-infrared spectroscopy (NIRS) [S. Fantini, Neuroimage 85, 202–221 (2...
متن کاملNeural Control of Breathing and CO2 Homeostasis
Recent advances have clarified how the brain detects CO2 to regulate breathing (central respiratory chemoreception). These mechanisms are reviewed and their significance is presented in the general context of CO2/pH homeostasis through breathing. At rest, respiratory chemoreflexes initiated at peripheral and central sites mediate rapid stabilization of arterial PCO2 and pH. Specific brainstem n...
متن کاملSecretory immunoglobulin A and cardiovascular activity during mental arithmetic and paced breathing.
The role of the autonomic nervous system in secretory immunoglobulin A (sIgA) responses to laboratory challenge was explored in a study in which sIgA and cardiovascular activity were recorded at rest and during mental arithmetic and paced breathing. These tasks were selected to preferentially engage the sympathetic and parasympathetic nervous systems, respectively. Mental arithmetic elicited a ...
