This experimental study aimed to evaluate the effect of relaxation techniques on anxiety levels, and the relation between anxiety and the concentration of Immunoglobulin A. The study was carried out in a maternity hospital in a city of the State of Espírito Santo, Brazil. The sample was composed of 60 puerperae. The information on the variables: age, education, marital status, type of childbirth, and parity were collected with a specific form; the trait and state of anxiety were based on the State Trait Anxiety Inventory (STAI/IDATE); and the level of salivary IgA was obtained through immunoturbidimetry. The application of the Mann-Whitney, Wilcoxon, and Pearson's correlation statistical tests showed a significant reduction in the levels of the state of anxiety in the experimental group (p = 0.01); there was no correlation between the trait and state variables of anxiety and the salivary IgA level; both groups (experimental and control) showed trait and state of medium-intensity anxiety.
