Table 2.

Descriptives (mean and standard deviation) of objective, subjective, and physiological outcome variables. Asterisks indicate a significant difference with the first bout (out of bath baseline) in the same condition (p < 0.05 = *, p < 0.01 = **, p < 0.001 = ***). Diamonds indicate a significant difference with the corresponding neutral condition (p < 0.05 = ◊, p < 0.01 = ◊◊, p < 0.001 = ◊◊◊). Objective cognitive measures are reported in [10], yet repeated in this table for completeness
