Re: How much water to drink

[Guest guest]

I'd figure if you took average urine output and added 10% for

evaporation you'd get the number...

Avg urine output 800 to 2000 ml = 27.05 oz to 67.83 oz.

+10% for evaporation = 29.76 oz to 74.61 oz or no more than 0.58 gal

Given avg. weight from high to low approx 105-190, so over 190 would

be more water than that but on the same scale.

Evaporation at 10% is rough and would have to be adjusted for actual

amount to get specific.

Learned about this recently when 24-urine volume was 3.5 gallons,

still don't know why, not sugar or insulin.

If you really want to know the optimal amount of water, you need to talk to

a sports physiologist. The local high performance athletes apparently drink

enough so that their urine is barely coloured. I don't know if they actually

use a colour comparator (or if they compensate for riboflavin in the diet).

Suffice to say, that the intake must match metabolic rate to excrete

catabolic products and to meet loss by sweat and from breath. Greater intake

in hot climates, hot weather and high levels of activity. This might mean a

variation by as much as a factor of 5 over the year for an individual who is

sedentary in winter and very active in summer.

There will be a marked variation in terms of body weight, individual

physiology and activity patterns. If you van pin a figure on your own needs,

well and good, but it's very hard to generalise. Eight glasses a day ? How

big is a glass ?

My advice, drink as much as you are comfortable with, there are better views

in life than the inside of a dunny.

Hi, .

Did you really mean to say that your 24-hour urine volume was 3.5

GALLONS? Or did you mean liters or quarts?

3.5 gallons is a very large 24-hour urine volume. I've heard of one

that was about 7 liters per day, but that's the highest I've heard

until now.

Many PWCs have diabetes insipidus (not the same as diabetes mellitus)

as part of CFS, and I think that accounts for the elevated urine

volumes and the consequent thirst and low total blood volume

(hypovolemia), which in turn contributes to the orthostatic problems

and the low cardiac output that many have. In my hypothesis, the

diabetes insipidus in CFS is caused by low output of antidiuretic

hormone (arginine vasopressin), which in turn is caused by

glutathione depletion in the hypothalamus.

A nurse once told us, take your body weight, divide it by half, and

that's the amount of water you should drink every day. So a 100 lb

person should be drinking 50 oz of water each day, which is 6-1/4

eight-ounce glasses of water a day. Do the conversion appropriately in

metric measurements of half your body weight. It is amazing how little

we all drink when we really measure it. Eight ounces in the USA is only

one cup, or as we old-timers used to measure, one cheese glass full.

This goes back to when you bought pimento type cheese spread in glasses

for the holidays that you continued to use throughout the year; even

Welches grape jelly used to come in these decorated " cheese " glasses

that we all looked forward to collecting with current cartoon or movie

figures decorating them.

Happy holidays to everyone the world over, wishing healthy days and

nights for all of you.
