Handwarming and relaxation in temperature feedback: positive placebo effects.

L Onoda

    Biofeedback and Self-Regulation
    |March 1, 1983
    PubMed
    Summary

    Hand-warming and cooling feedback did not significantly alter subjective relaxation. Feelings of relaxation were negatively correlated with temperature change and linked to nonspecific expectancies, not the temperature manipulation itself.

    Area of Science:

    • Psychology
    • Psychophysiology
    • Behavioral Medicine

    Background:

    • Subjective relaxation is often associated with thermal changes.
    • Biofeedback techniques, including temperature feedback, are explored for managing stress and promoting relaxation.

    Purpose of the Study:

    • To investigate the efficacy of hand-warming and hand-cooling biofeedback in altering subjective relaxation.
    • To determine the relationship between directed temperature change and reported feelings of relaxation.

    Main Methods:

    • Sixteen participants were randomly assigned to either a warm-relax (WR) or cool-relax (CR) group.
    • Participants underwent eight 1.5-hour sessions involving temperature feedback.
    • Subjective relaxation levels were assessed after each session.

    Main Results:

    • Both WR and CR groups showed significant temperature changes in the intended directions.
    • No statistically significant differences were found in the reported subjective relaxation levels between the groups.
    • A negative correlation was observed between the direction of temperature change and subjective relaxation.

    Conclusions:

    • Hand-warming and cooling biofeedback, despite achieving significant temperature changes, did not directly enhance subjective relaxation.
    • The study suggests that perceived relaxation may be influenced more by nonspecific factors, such as participant expectations, than by the actual thermal manipulation.
