Question
I need to know if I'm on the right track with my answer to thescenario below. Imagine you are vacationing in Florida. On one day you swimall afternoon in the ocean and on another you swim all afternoon ina freshwater lake. At the end of one of those days you areparticularly thirsty and on the other not very thirsty at all, eventhough on both days the temperature and levels of sunlight aresimilar. You also spend about the same amount of time outside, youractivity levels don't differ greatly, and you drink about the sameamount of water each day. Which day do you think you would be thirstier and why? My answer is that I would be thirstier on the day I spentswimming in the ocean because the salt in the water would draw outthe water from the body. To prevent dehydration, the brain tellsthe body to drink water to replenish what was taken away from thesalt water. The body normally loses water anyway throughevaporation, but the salt water causes even more water to be lostthan normal. Since freshwater does not contain salt, it isdifferent. Am I wrong or missing anything important here? I need to know if I'm on the right track with my answer to thescenario below. Imagine you are vacationing in Florida.
