Subject: RE: Dehydrate while sleeping?I wouldn't worry a whole lot about it. There are insensible losses while you sleep, namely from sweating and breathing. All the light yellow color means is that your kidneys are working exactly the way they're intended, i.e. concentrating solutes in the urine when there's not as much water to get rid of. I tend to agree that the mega-hydration/obsess over urine color thing isn't the best, because there are down sides to overhydration as well--in the extreme, it can lead to hyponatremia, which can be fatal. As long as you're drinking your 8 glasses of water a day and staying hydrated during exercise, there's not much to worry about. There's no benefit to chugging water all day long and working on your race horse impersonation. |
