Since your skin can be directly connected with the capillary, heat can be transferred through blood remaining in the capillary and finally creates the equilibrium by spreading it to every corner of the body. Thus the temperature in each part of the body remains quite same. On the other hand in the winter your skin receives heat from blood as well as receives heat from external objects and thus keeps the body getting warm every time.

Water resistance
