Effects of thermal stress on the activity of selected lysosomal enzymes in blood of experienced and novice winter swimmers

Abstract

Winter swimming seems to have no effect on the activity of the lysosomal enzymes. By contrast, an increase of certain lysosomal enzymes after the sauna suggests that it may be deleterious to the lysosomal membranes. Furthermore it seems that regular winter swimming combined with sauna, according to hormesis theory, induces some adaptive response.
