Secretory immunoglobulin A (sIgA) in saliva and cardiovascular reactions to mental arithmetic and cold pressor tasks were recorded in 16 healthy young men on two sessions, 4 weeks apart. Both tasks elicited significant increases in sIgA secretion rate, reflecting increases in both salivary volume and sIgA concentration. Whereas mental arithmetic elicited a mixed pattern of alpha‐ and beta‐adrenergic cardiovascular reactions, the pattern of reactions to cold pressor was predominantly alpha‐adrenergic. Task levels of sIgA secretion rate, sIgA concentration, and saliva volume showed moderate to high test–retest reliability ( r = .52–.83), although test‐retest correlations were less impressive for change scores ( r =−.19–.53). The pattern of correlations between change in sIgA secretion rate and cardiovascular reactivity variables was inconsistent.
