View Full Version : The science of hydration

In case anyone is interested in reading a little bit about what dehydration does to your body on a molecular level I did a bit of a write up on it. Feel free to give it a look. Just some things to consider along with your backcountry nutrition. Thanks everyone, and keep preparing, hunting season is just around the corner.

Wow, good read and good information on the importance of water. Thanks for sharing your blog with us and good luck with the marriage this year...hope she'll let you keep bow hunting. ;)

Cool write up. Something I've learned along the way is that, at least for me.... drinking water straight up is a waste (when supply is limited). First straight water is harder for your body to process then water with something in it. That something could be coolaid, tea, whatever, that helps to break the surface tension of the water enabling the body to better manage the uptake of water in the intestine. I've noticed that in some early backcountry hunts that before long I was peeing out just the same (color wise) as what I'm putting in. Seemed like my body was just getting rid of it. I did some reading and thats what actually happens. I'm no scientist by I know at times the body does not like large amounts of water as it throws off the natural balance of salts. You can actually die from this (not in ways us backcounty hunters conduct business), but it happens. I do drink straight water out of my camelbaks but often throw in a nalgene bottles worth of cherry stevita (good stuff, a little goes a long way too) and I believe I'm able to stay hydrated better. I do homemade rehydrated meals for dinner and that's another nice way to get in some more fluids in ya.

Any of you guys seen the camelbak flow meter? That thing is sweet. I hate taking my pack off, opening the sleeve, to look in and see how much water I got left. This thing counts your water down for you in oz or whatever you set it to. It's pretty accurate, when you don't have ice forming in the line, lol.

A flow counter sounds great. How much does it weigh?

As for hydration, I am a scientist, and that is a good write up.

Thankyou. I appreciate it. I really tried to avoid going too in depth and keep things simple so that people could get the main idea of how water is crucially tied to energy level and cellular respiration. I know many times in the backcountry I do not get thirsty even when I am dehydrated, so I try to make a conscious effort to keep my water intake at a good, healthy level.

Good read.

Two three ounces maybe... Here's a link: http://www.camelbak.com/sports-recreation/accessories/flowmeter.aspx

Good break down of most everything, good post.

I also find it nearly impossible to hydrate adequately with water alone. There are times that I can' t prevent cramping and even muscle strains when it is hot and humid and I am training at a high level. I swear by Hydrate and Recover. This has helped me a lot in my training and on my western hunts

By all means go ahead and buy into all the hype put out by the hydration additive companies, you are free to spend your money where ever you please.
Humans have been drinking plain water for millions of years with no ill effects.

They key to hydration is not to ingest diuretics and to drink lots of water. Drinking water with large concentration of solutes can have the same affect as drinking salt water whereas the water will leave the cells in your gut to balance the concentration gradient. I might be a little off since school was a decade ago. Deionized water can equally be bad since the reverse is true. The water will enter the cells to equalize the concentration gradient and possibly rupture them. I couldn't possibly tell you what concentration to drink. I'd think a diluted Gatorade mix would be ok but I know caffeine is diuretic and sugar might be too. Please feel free to correct me if I'm misremembering something g

Hydration is all about balancing water and electrolytes (mineral ions; could be chloride ions in the case of table salt NaCl or things like magnesium or calcium ions). Gr8 is correct, just plain ol water has worked for millions of years but remember, our ancestors did not consume even close the amount of salt we do today; even if you're careful it is VERY easy to eat too much salt. However, mineral ions and salts are imperative ingredients for the conduction of electrical impulses to move through the body and do things like move muscles.

Point is, if you really want to hydrate properly, watch what you eat just as closely as worrying about what you drink.

Please forgive me if this was all explained in the write up-I really want to read but I am getting blocked for some reason. Maybe I shouldn't be doing this at work. HA!
