Water tempatures

When I first found out that the water temperature could have effects on a divers body, I seriously laughed in the other person, that told me, face. After I was done laughing, then they explained that the different temperature, changes the way that your body would react to the water when you jump in. The hot water is nice and relaxing and it loosens your muscles after you do physical activities but while your diving and swimming, like doing physical activity (not like at your pool at home, like actually diving, especially in swimming, like laps, and doing it very seriously) it may seem nice at first but your body will react to the water in very negative way. Cold water, to me and I think it's okay to speak for others as well, is horried at first but your muscles and your body will get used to it and you'll be able to do more in the water. I'm not saying dive or swim in freezing cold water, but in a water temperature that's a little higher than room temperature, so that it doesn't have negative effects on your body.
