you guys forget why we sweat...
to cool the body.
so unless the the water temp + your activities gets higher than your current body temp, you wont need to sweat...

One last thing, he thinks all guns should be banned and thinks Im a lunatic for having 20 firearms and a website dedicated to my love for them, and when confronted with the question of "Well, what will we do to defend ourselves from the criminals that already have guns?" He says "We'll just call the cops.
lol...
on a serious note, have your friend read the story of warren vs district of columbia...

you do sweat under water. as a swimmer i can tell you this. Based on some peoples ideas that if the water is colder than you are you won't sweat, they are ****ing stupid. haven't you ever taken a run when it is below freezing outside(below 32 degrees Fahrenheit)? you still sweat even tho the air/water around you is still colder than the temperature of your body. sweat is a by product of your body cooling itself off. Even though the temperature around you is colder than you are that doesn't mean your body doesn't heat up. it is insane to think you don' sweat while swimming.

i had a full ride to swim in college unfortunately during the last part of my senior year in high school i dislocated my shoulder. my full ride was taken from me and i am just now getting back to being able to swim again(2 years, surgery 4 months ago repaired the damage). i graduated 2 years ago and i wish i would have never hurt myself.
but ya, you sweat alot while swimming, you use ever muscle in your body when you swim, no other sport can claim that!

Sports magazines and books are filled with articles about the need to drink during sport. Runners, cyclists, triathletes, tennis players and footballers of all codes are educated about the dangers of dehydration that follows sweat losses during exercise. The human body is like a car in that it produces heat when it is moving, and it needs to cool itself, like the radiator in a car, by producing sweat to evaporate. However, sweating means that your body is losing water - from the blood, and from inside and around cells. This causes problems which build in proportion to the fluid deficit. All levels of dehydration reduce exercise capacity and endurance, and increase the perception of how hard the work is - it just depends on how sensitively you need to measure this. As little as 2% loss of body fluids (1-1.5 litres of sweat) can produce a detectable reduction in an athlete's capacity to do high intensity exercise in hot conditions, and also reduces concentration and mental skills. And the margins between winning and losing sports competitions are often much smaller than the "detectable" levels reported in studies.
In most sports, athletes are aware that they are sweating. They can see the sweat on their skin, and their clothes and hair becomes soaked. Sweat loss varies with the individual and their sport. Some athletes sweat more than others, especially when they are acclimatised to hot conditions. Other factors influencing sweat rates are the environmental conditions (how hot, humid and windy it is) and the intensity of the exercise. The harder the athlete is working, the more heat that their body is producing.
In most sports conditions when the athletes are working hard, scientists tell us to expect sweat rates of 1-1.5 litres per hour.
But these figures apply to athletes exercising on land. What of athletes who exercise in water, such as swimmers, water polo players, water aerobics devotees and lifesavers? Can you sweat when you are fully immersed in water? How can you tell if your body, your hair and your clothes are already wet? Do you need to sweat to lose body heat produced by exercise - or is your body sufficiently cooled by the water it is swimming in? These are some of the great mysteries of life, and in attempting to find an answer to these, we actually found some other unsolved questions: Why do you want to go to the toilet as soon as you get into a pool? And do swimmers pee in the pool? The original purpose of our enquiries was to see if dehydration was a real issue for swimmers and other aquatic athletes, and how well our current group of athletes looked after their fluid needs in a typical exercise session.
The problems of dehydration in competition are likely to be a problem only to open water swimmers. But that's another story. For our study we confined ourselves to the training sessions undertaken by elite swimmers - often 1-2 hours of high intensity work. And we conducted our study in Atlanta in 1995 during the camp preceding the Pan Pacific Games. Training was carried out in an indoor pool that was not air conditioned. Therefore, although the swimmers were protected from direct sunlight, they did their training in hot (300C) and humid (60% relative humidity) conditions. The pool temperature was 290C - perhaps a degree or so hotter than many competition pools. We estimated sweat losses, dehydration and fluid intake with a technique that the AIS Nutrition Department has used to conduct a number of fluid balance studies with elite sports people. We weighed our athletes with accurate scales before a training session, and then again on completion of the session. The change in body mass was said to represent the fluid deficit produced during the training session, with % dehydration being this deficit divided by initial body mass.
We also monitored fluid "comings and goings" during the session. Drink bottles were weighed on small scales at the beginning of training and at the end, to estimate the amount of fluid consumed by the swimmer during the session. We also implored any athlete who needed to make a visit to the bathroom, to towel off, weigh, go to the bathroom, reweigh, and then get back into the pool.
By adding fluid intake, and subtracting the "losses" due to bathroom visits, we were able to estimate the total weight change, and thus sweat loss, during a training session. These calculations were done for 13 training sessions and a total of 295 observations. Since swimmers had done different work and different mileage in the pool, we decided to express the changes per kilometre of swimming. We also looked at the different types of sessions undertaken. (aerobic, anaerobic threshold, maximal oxygen consumption, race pace/speed work) to see if this influenced sweat losses and fluid intake measurements.
The results are summarised in the table below:
The results showed, that swimmers lost about 600ml of sweat during their typical training session (mean distance = 4km, mean time = approximately 1 hour of training). We found that male swimmers sweated more and drank more than female swimmers. And we saw that the "sweatiest" sessions were ones based on anaerobic threshold training. Not only did these sessions increase the rate of sweat loss, but the swimmers seemed less successful in drinking enough fluid to replace their losses.
Of course, we acknowledge that there are sources of error in this study method. We could not be sure that we accounted for all urine losses. In fact we noticed that the swimmers were much more likely to "hop out" for a visit during a training session than any other athletes that we have studied. Maybe this is due to the fact that they remain in general fluid balance, and sometimes even drink more fluid than they are sweating.
In summary, our study showed that swimmers do sweat, although at rates that are lower than land-trained athletes. And we showed that swimmers are able to replace their fluid losses during the session by drinking from water bottles kept at the end of the pool. These results perhaps represent the optimal situation. After all this was the national swim team, who are motivated and well educated. What's more, sports drink and water are made up at every session for them, and coaches remind them to bring their drink bottles to session and to drink between sets. It doesn't come more easy than that.
But these may be the conditions that you want for your team if you want them to train well-hydrated and at their best. While we haven't mentioned it in this article, fluid balance isn't the only reason to drink during a training session. If your drink bottle contains sports drink or cordial, it will provide your body with an additional source of fuel. This could be important for optimising training during prolonged hard workouts, or a heavy training week. In fact, this could be the most important reason for having a drink bottle and drink plan in place. Don't think that these strategies are only for Kieren Perkins or Sam Riley. Your body needs fluid and fuel because it is exercising, not because you are talented. If your muscles are doing the work, they deserve the best treatment.
