21. Do you need to drink when you swim?
Yes of course! While swimming, you should drink an additional 16 ounces of fluids two hours before a swim so you go into the pool well hydrated. Because, while you’re in the water, usually you do not notice that you’re sweating. As your body sweats when you swim, you need to replace that water. One of the most commonly asked questions is ‘do you sweat when you are swimming?’ The quick answer is yes, but that’s not quite all there is to it. Because you are in the water your body is cooled more rapidly so you probably aren’t aware that you are sweating most of the time.
To rehydrate properly afterward you should drink about 8 ounces every 20 minutes unless you’re in the pool for less than half an hour. Maybe you would think that by putting water on your skin you would improve moisture, however topical hydration is not as helpful as you would assume. Water that comes into contact with the skin quickly evaporates and takes away many of the skin’s natural oils.
