Social and behavioral factors associated with episodes of inhibitory breathing.
Previous research has shown that episodes of inhibitory breathing, characterized by low-frequency breathing, occur both in laboratory animals during intervals preceding avoidance tasks and in humans in the natural environment. The present study investigated social and behavioral factors accompanying episodes of inhibitory breathing that occur in the natural environment. Breathing frequency and tidal volume of ambulatory subjects were monitored via inductive plethysmography. Information concerning location, social environment, behavior, and mood was self-recorded in a computerized diary. The percentage of episodes of inhibitory breathing was found to be significantly greater in social situations than when subjects were alone. Additional analyses eliminated talking as an explanation for these effects. Inhibitory breathing was more frequent when subjects were sedentary rather than active, and inhibitory breathing was not associated with changes in mood or appraisal. Additional research is needed to determine the nature of the social interactions that elicit inhibitory breathing, its physiological concomitants, and its long-term health implications.
