  1. Values expressed as mean (range). Raw BL values presented for context thermal perceptions (1–7 scale) were only recorded during the experimental period (0–120 min)]. Results are presented every 30 min for clarity. Symbols are used to denote significant between condition interactions (e.g. *Hot vs TN, #Hot vs Cold, +TN vs Cold) and the ES (e.g. ‘trivial’, ‘small’, ‘moderate’, ‘large’, ‘very large’). The condition*time column exhibits at what time points a significant effect occurred within condition until the significant effect was lost (e.g. Tsk in HOT was significantly different from BL from 0–120 min). Significant main effects are highlighted in bold and italicized.
