The decrease in blood plasma results in a decrease in venous return, the volume of blood returning to the heart, and therefore a decrease in stroke volume, the volume of blood ejected from the left ventricle per beat. Or give it a thumbs up! A lack of blood at the skin decreases the sweating response, which in turn causes an increase in body temperature which if not lowered, in extreme cases can lead to heatstroke.
