Drinking alcohol in a survival situation - 03/29/13 08:57 PM
I know we have all heard this conversation before, "don't drink alcohol because it is a diuretic and excessive urination will cause dehydration". That is what we have all heard and we swear by it. But is it true?
Granted, drinking 70-proof alcohol will do that. Whiskey and survival don't go hand in hand if it causes you to dehydrate. But what if you could evaporate the alcohol content and keep the remaining water? Alcohol should evaporate at a temperature below water boiling since its boiling point is 173*F so if you heated it you could reasonably reduce the alcoholic content.
Now lets say you have 5-6% beer. Is the alcoholic content already low enough to have a minimal diuretic effect? Or is it the salts in the beer that cause an imbalance and thereby cause you to urinate? We all know the effect of pounding down several and needing to find the washroom shortly after but part of that is because we have consumed so much fluid!
But if you came across a single beer in the wilderness, would you drink it or throw it out? I just watched an episode of Dual Survival where at the start of the show they reach into the pack to check out their supplies. http://www.youtube.com/watch?v=FEalKkJnrfM They immediately dump the beer because of its diuretic properties. Is this a mistake? Wouldn't consuming 1 beer, even relatively slowly have little diuretic effect? The beer is still 94% water and water is necessary for the body thus you wouldn't the hydrating effect of the water content would be greater than the diuretic effect of slowly consuming 1 beer.
I know they were trying to make a point to the viewers but in this case is it a valid point? (I don't want to read rehashed quotations from some old survival guide that we have accepted as gospel. I want honest opinions based on facts, chemistry and real world studies because sometimes its better to take a step back and think and challenge conventions.)
