POINT!
| With sweating, the (blue→red) negative feedback increases the number of water channels. |
① Sweating increases plasma osmolarity, and water reabsorption (through the water channels) decreases plasma osmolarity. These effects are in the opposite direction (blue).
② Since these effects are in the opposite direction (blue), negative feedback increases (red) the number of water channels and the water reabsorption. The plasma osmolarity-decreasing effect of the water reabsorption becomes stronger, and plasma osmolarity returns to normal.

Sweating increases decreases plasma osmolarity, and water reabsorption (through the water channels) increases decreases plasma osmolarity. Since these effects are in the same opposite direction, negative feedback increases decreases the number of water channels.
