Mean decreases in skin temperature and CVC during each whole-body cold stress in protocol 1

	Cutaneous vascular conductance (AU)
	Changes in skin temperature(°C)	Pre-cold stress	End cold stress	Relative reduction (End versus Pre-cold stress)
Cold stress 1 (Ringer's)	− 4.5 ± 0.2	0.49 ± 0.20	0.17 ± 0.05	63.0 ± 4.1%
Cold stress 2 (SNP 8.4 × 10−6m)	− 4.6 ± 0.2	0.40 ± 0.13	0.16 ± 0.05	57.1 ± 4.7%
Cold stress 3 (SNP 8.4 × 10−5m)	− 4.4 ± 0.3	0.63 ± 0.28	0.28 ± 0.17	57.0 ± 3.6%
Cold stress 4 (SNP 8.4 × 10−4m)	− 4.6 ± 0.4	1.17 ± 0.60	0.69 ± 0.51	44.5 ± 5.4%*
Cold stress 5 (SNP 8.4 × 10−3m)	− 4.7 ± 0.6	1.66 ± 0.56	1.14 ± 0.42	28.8 ± 7.9%*
