More than just warmth-The perception of warmth and relaxation through warming compresses.

Objectives: To differentiate the effect of ginger and mustard as warming ingredients from the effect of calmness & attentiveness and thermal warmth in chest compress application.

Design & Setting: In an exploratory, controlled, single-blinded study, we compared the effect of ginger and mustard in healthy adults.

Interventions: Participants received four different chest compress types over four weeks: simple dry, hot water, with ginger powder and with mustard flour.

Outcome Measures: The somatic and psychological experience of the participants was collected through psychometric measurements (list of somatic complaints (B-L), questionnaire on mental state (MDBF), 5-point-rating scale (RS) containing eight questions on the experience of relaxation and warmth) and was further complemented through qualitative interview data.

Results: Participants (15 female and 15 male) ranged between 21-36 years (M = 27). No significant changes in the B-L could be found. The MDBF found significant change towards calmness after every application (P < 0.05). Significant improvement in mood was found after the ginger compress (P = 0.00). The RS found significant changes towards relaxation (P = 0.00), emotional balance (P = 0.03), deep (P = 0.03) and slow (P = 0.00) breathing as well as warm hands (P = 0.03) and feet (P = 0.00) with the ginger compress. No significant changes on the RS could be found after the mustard compress. Qualitative-phenomenological data underlined the difference between ginger and mustard in quality of warmth. No adverse effects were reported.

Conclusions: Ginger and mustard induced a strong and lasting response on perceived distribution of warmth and relaxation. Compound effect quality could be differentiated: mustard triggered a strong relaxing effect after the intervention and ginger a warmth quality that spread throughout the body.
