Breathing directly interfaces with the autonomic nervous system, which strongly influences immune behavior.
Subcomponents of Breathing and Immunity
Parasympathetic activation
Slow breathing with extended exhales supports vagal tone, associated with recovery and reduced inflammatory signaling.
Stress modulation
When stress hormones remain elevated, immune function becomes dysregulated—either overactive or suppressed.
Recovery acceleration
Breathing practices can shorten the time needed to shift from stress to recovery after training or emotional load.
Practical direction: Slow the breath. Lengthen exhales. Use breathing intentionally after stress.
