Inter-correlation table between selected variables (Pearson's r-correlation values). SFA = stereotypic feminine attributes; SMA = stereotypic male attributes; AI = anger expression inwards; AO = outwardly expressed anger; AC = controlled anger expression; TDCE = thermal discomfort from cold extremities; log (SOL) = log-transformed values of estimated sleep onset latency (min); awake = estimated time awake (min) during a night sleep episode. *p < 0.05, **p < 0.01, ***p < 0.001
