???? Blood counts before and after a coldwater application show a very marked increase in the number of red and white blood corpuscles. This does not mean that the cold water has in a moment created new blood cells, but it means that the blood has been stirred up and sent hurrying through the system, that the lazy blood cells which were lying inactively in the sluggish and stagnant blood stream and in the clogged and obstructed tissues are aroused to increased activity.
???? As the blood rushes back to the surface it suffuses the skin, opens and relaxes the pores and the minute blood vessels or capillariesa nd thus unloads its impurities through the skin.
