Table 1. Temperature, tactile sensitivity, and manual dexterity data at distinct timepoints
across conditions. Tre = rectal temperature; TS = thermal sensation; TC = thermal comfort;
PPA= Purdue pegboard assembly. T1 = timepoint 1; T2 = timepoint 2; T3 = timepoint 3. Data
are presented as mean (SD).

* For Tre, T1 = pre-thermal manipulation; T2 = post-thermal manipulation but pre-hand
cooling; and T3 = midpoint of hand-cooling protocol. For all other measures, T1 = pre-hand
cooling; T2 = immediately post-hand cooling; and T3 = midpoint of lifting task
