In a within-subject crossover design, participants (<em>n</em> = 78) consented to complete one session each of pool-REST and chair-REST, an active comparator controlling for the effects of simple relaxation and expectation.

Although both REST conditions showed significant decreases in ratings of stress/anxiety, negative affect, and stimulant craving, pool-REST was associated with greater increases in positive affect, cardiorespiratory interoceptive awareness, heart rate, and systolic blood pressure than chair-REST.
