The immediate effects of 10-minute relaxation training on salivary immunoglobulin A (s-IgA) and mood state for Japanese female medical co-workers.
This study examined the effects of relaxation training on salivary IgA (s-IgA) and mood state in Japanese female medical workers. Participants were enrolled and assigned to relaxation or control groups. The relaxation group Japanese female medical workers (n = 38, mean age = 33.5 years, SD = 9.6) participated in a lecture on stress for 1 h and had 10 min of relaxation training. The control group (n = 41, mean age = 35.0 years, SD = 8.6) participated in only the lecture. S-IgA was measured, and a self-report mood questionnaire administered before the lecture and then again after the relaxation training for the relaxation group. The control group was measured before and after the lecture. The results showed that s-IgA levels significantly increased after relaxation training in the relaxation group compared with the control group (p = 0.03). A marginally significant intervention effect was observed for mood state (p = 0.06) ; indicating that the relaxation group was more likely to reduce any fatigue and confusion than was the control group. These findings suggest that short-time relaxation training is effective in relaxing mood and causes changes in immunological function.
