Hydration

[Doug Taylor]

Speaking of hydration from the deep vein thrombosis thread...

I've recently started running again and I drink A LOT of water now.

In flight, I might drink about 16-32 ounces of water per hour. I've noticed that when I make a concerted effort to hydrate myself, I don't come home from a four day trip feeling like a zombie.

My question. How much water is "too" much? Is there a healthy water consumption target in flight?

I power drink water the same way. Seems that as long as I keep at it, even if I can't run for a month for some reason, I stay in better condition. I would venture that you can't drink too much, your body will excrete what you don't need, but I will differ to the experts on that. I do know that you probably feel better after a trip due to both the water and, even more, to the running.

I wouldn't think there would be a time where you could drink too much water. we're made of what, 95% water?

I think I'm going to wait for the doctor, but thanks!

Y'all obviously missed the memo on Dihydrogen Monoxide (DHMO). It's a killer.

The link from Bandit Driver is excellent. One of the best things to do is watch the color of the urine, if it is light yellow, that is the goal. When it is the color of water, you should slow down a bit. If it is dark yellow, one should drink more water. Here in Phoenix we tend to drink a lot of water because of the insensible loss of water through insensible perspiration in the dry climate. Tourists frequently get dehydrated here because they don't realize the water loss. Our fire department is always air-lifting tourists off the hiking trails on the mountains. It is different in the southeast US where humidities are high and there is more sensible perspiration. The big thing is common sense.

In the clinical practice of medicine, we tend to see water intoxication in patients with psychiatric disorders, tumors or infections of the lung, tumors of the brain and in heavy beer-drinking alcoholics. For health people to develop water intoxication, one would need to push water consumption to the point of being uncomfortable because of the volume one would have to consume and the kidneys are really very efficient.

Hope this helps Doug

Me too. It's amazing how much better I feel. I don't get sick nearly as often either.
