It’s proximity to the Pacific Ocean.
Explanation: Vancouver has an oceanic climate and has, in winter, the second highest average temperature in the country, just behind Victoria. Its summer, however, is one of the mildest in the country.
The correlation between thirst and kidney function is the following:
Thirst is the regulator of the state of hydration, necessary to eliminate the osmotic load, it can help preserve kidney function.
The instantaneous perception of osmolarity in the blood allows us to generate the sensation of thirst.
In other words, this sensation is in turn caused by a high concentration of osmolytes (compounds that affect osmosis, or the way it is measured, osmolality or osmolarity) or by hypovolemia.
The receptors that control cellular dehydration are called osmoreceptors and are located in the lateral preoptic area.
Osmoreceptors detect this decrease in cellular water and trigger thirst, as well as the release of Anti-Diuretic Hormone into the bloodstream.
Antidiuretic hormone helps regulate the amount of water in the body by controlling the amount of water excreted by the kidneys.
Therefore, we can conclude that the sensation of thirst appears the sodium concentration is higher than normal, when drinking water, the concentration gradient is reduced, which allows the normal functioning of kidney function.

A control group is a group that does studies or Experiments that does not receive treatment by researchers and is then used as a benchmark to measure how the other tested subjects do. Ex: Experimenting Arizonas and water together.
