With sweating, the plasma osmolarity {decreases~=increases}.  The effect would be the {=same as~opposite to} that of reabsorption of water by the kidney, which {=decreases~increases} plasma osmolarity.  The effect of the reabsorption would be {=too weak~too strong} prior to control by negative feedback.  Negative feedback {~=increases~decreases} the synthesis, secretion, and blood concentration of ADH.  This in turn {~=increases~decreases} the number of water channels in the kidney causing {~=increased~decreased} water reabsorption. Urine osmolarity {~=increases~decreases} while volume {increases~=decreases}.  This {~=decreases~increases} plasma osmolarity, {~=returning to normal~separating from normal}.
The effect of increasing in ADH is to {increase~=decrease} the plasma osmolarity .

narrated video explanation

video prior to the decrease in ADH
Prior to ADH decreasing (at baseline), we will make the assumption that the subject is in homeostasis with normal plasma and urine osmolarities (isotonic) and volumes.

video just after the increase in ADH
Step 1: Suppose that the synthesis, secretion, and blood concentration of ADH decreases.
The water channel-increasing effect of ADH decreases, thereby decreasing the number of water channels. This decreases the reabsorption of water by the kidney.

video showing the changes in plasma and urine after the increase in ADH
The ratio of Na+ to water entering the plasma due to reabsorption increases. This increases plasma osmolarity (hypertonic). Because a higher ratio of Na+ to water leaves the tubule due to reabsorption, the fluid remaining in the tubule has a lower osmolarity (hypotonic). Also, with a decrease in water reabsorption, there is more water remaining in the tubule. Overall, the urine becomes less concentrated (hypotonic) and higher in volume.
