Changes in distal skin temperature (${\overline{\mathrm{T}}}_{\mathbf{dist}}$).${\overline{\mathrm{T}}}_{\mathrm{dist}}$ of both the D and non-D groups were significantly lower during the period ranging from 0 to –30 minutes in winter than they were during that same period in summer. #P < 0.05, comparisons between haplogroup D values taken in summer and winter. §P < 0.05, comparisons between haplogroup non-D values taken in summer and winter.
