I'm lurking on this thread. Just saying hello!

I'm 55 and I've noticed this year more than ever before that I can't really use my propensity to sweat as a gauge to how much I should be drinking. It hasn't really been hot in Kansas yet, so even on longer rides, I don't sweat through my shirt. On hot, hot days, I'm sure I will, but so far this year on my rides, it seems like the sweat is drying off me in the wind. I'll ride for an hour, not notice a drop of sweat on me, and realize, wow, I am thirsty and need to drink!

When my enlarged prostrate was impinging on my ability to empty my bladder I was cautious as to how much water I would drink. After Greenlight laser surgery I can fully empty my bladder and find myself drinking a great deal more water throughout the day. I gave blood a few weeks ago and the tech said my blood as flowing very well and he ascribed that to my being well hydrated.

A key problem with being dehydrated is that your blood thickens and is less effective in supporting your organs. Waiting to be thirsty before drinking more water is ill advised. I drink 10 oz of water before I start a ride so I have enough fluids to be able to sweat.
