| With sweating, the (blue→red) negative feedback facilitates (the synthesis, secretion, and blood concentration of) vasopressin (anti-diuretic hormone, ADH). |
① Sweating increases plasma osmolarity, and reabsorption (through the water channels, which are increased by vasopressin, ADH) decreases plasma osmolarity. These effects are in the opposite direction (blue).
② Since these effects are in the opposite direction (blue), negative feedback facilitates (red) (the synthesis, secretion, and blood concentration of) vasopressin (anti-diuretic hormone, ADH). This increases the number of water channels and the reabsorption of water. The plasma osmolarity-decreasing effect of the reabsorption increases, and the plasma osmolarity becomes adequate.

Sweating increases decreases plasma osmolarity, and reabsorption (through the water channels, which are increased by vasopressin, ADH) increases decreases plasma osmolarity. Since these effects are in the same opposite direction, with sweating, negative feedback facilitates inhibits (the synthesis, secretion, and blood concentration of) vasopressin (anti-diuretic hormone, ADH).
