We assessed the stress relief effect of spa bathing by measuring sensitive salivary stress markers, cortisol and chromogranin A (CgA). From 12 healthy males, saliva samples were collected immediately before and after spa bathing, and 30 min after that. Salivary cortisol and CgA levels were determined by ELISA. Salivary cortisol levels decreased after spa bathing. This tendency was more pronounced in individuals with higher levels of stress. The high-stress group showed lower salivary CgA levels after spa bathing, while the low-stress group higher salivary CgA levels in the same condition. These findings suggest that the spa bathing has a moderate affect on the stress relief.

We investigated the effect of laughter on salivary endocrinological stress marker chromogranin A (CgA). In saliva samples collected from 11 healthy males before and after watching a comic film or a non-humorous control film, salivary CgA levels were determined by enzyme-linked immunosorbent assay (ELISA). Samples taken after watching the comic film showed increased levels of CgA. This tendency was more pronounced in individuals with lower initial levels of stress. The control samples showed no significant change in CgA levels. Stress score, subjectively evaluated using a visual analog scale, decreased significantly after watching the comic film. These findings suggest that, in addition to a stress relief effect, laughter can bring about feeling uplifted or fulfilled.
