Hello, /sci/. I'm a Boston college student looking to drink good water. Does it make sense to buy a reverse osmosis system like picrel? Simple activated carbon filters don't really do much, and I'd like to avoid buying bottles every week.

Why don't you just drink tap water instead? What the fuck is reverse osmosis? Why don't you just distil water in a pot and drink it?

1. Tap water is contaminated.
2. Reverse osmosis is the process by which water is actively moved across a membrane against the concentration gradient.
3. Not a bad idea, but takes up a lot of time.

Destilled and deionised water are not safe to drink. That would significantly increadse the osmotic potential of the intercellular matrix, and even that of your blood. Drinking destilled water constistantly over a long enoough period can be fatal.
That sayed, i totally understand not wanting to drink tap water, or even bottled water. I would suggest springwater. Even springwater needs filtering because of amoebas, but its your safest bet. Get spring water, put it through a coffe filter, boil it, and bobs your uncle. Safest, cleanest water you can get.

I dont understand. Pic related show hypotonic solution bursting a cell. Which part of that do you disagree with? The principles of osmosis? This is one of the easyest things to verify with your own eyes. Make a series of more and more diluted soultions ending with deionised water. Take a large sample of single cell layer from idk an onion skin, or a blood smeer. Add solutions. Put under microscope. Pic related is pretty much what youll see above the isotonic solution.

if you drink water without any salt ions for a long period you will fuck the osmoregulation balance in your body

Retard, your cells are a living interconnected system, the "osmotic potential" of your blood and intracellular matrix is determined by the solubels and minerals that you consume as well as your renal function. Drinking distilled water does not lower the general osmolaritiy of anything, as long as you're not completly fasting. Western diets for instances are EXTREMELY rich in sodium, so much even that it even destroys some people kidneys. God this level of retardation on sci is insane

seems that the "living interconnected system" is more complicated than you previously thought

>i"t has been adequately demonstrated that consuming water of low mineral content has a negative effect on homeostasis mechanisms, compromising the mineral and water metabolism in the body. An increase in urine output (i.e., increased diuresis) is associated with an increase in excretion of major intra- and extracellular ions from the body fluids, their negative balance, and changes in body water levels and functional activity of some body water management-dependent hormones.Experiments in animals, primarily rats, for up to one-year periods have repeatedly shown that the intake of distilled water or water with TDS ? 75 mg/L leads to: 1.) increased water intake, diuresis, extracellular fluid volume, and serum concentrations of sodium (Na) and chloride (Cl) ions and their increased elimination from the body, resulting in an overall negative balance.., and 2.) lower volumes of red cells and some other hematocrit changes"

>Results of experiments in human volunteers evaluated by researchers for the WHO report (3) are in agreement with those in animal experiments and suggest the basic mechanism of the effects of water low in TDS (e.g. < 100 mg/L) on water and mineral homeostasis. Low-mineral water markedly: 1.) increased diuresis (almost by 20%, on average), body water volume, and serum sodium concentrations, 2.) decreased serum potassium concentration, and 3.) increased the elimination of sodium, potassium, chloride, calcium and magnesium ions from the body. It was thought that low-mineral water acts on osmoreceptors of the gastrointestinal tract, causing an increased flow of sodium ions into the intestinal lumen and slight reduction in osmotic pressure in the portal venous system with subsequent enhanced release of sodium into the blood as an adaptation response. This osmotic change in the blood plasma results in the redistribution of body water; that is, there is an increase in the total extracellular fluid volume and the transfer of water from erythrocytes and interstitial fluid into the plasma and between intracellular and interstitial fluids. In response to the changed plasma volume, baroreceptors and volume receptors in the bloodstream are activated, inducing a decrease in aldosterone release and thus an increase in sodium elimination. Reactivity of the volume receptors in the vessels may result in a decrease in ADH release and an enhanced diuresis. Ingestion of distilled water leads to the dilution of the electrolytes dissolved in the body water. Inadequate body water redistribution between compartments may compromise the function of vital organs. Symptoms at the very beginning of this condition include tiredness, weakness and headache; more severe symptoms are muscular cramps and impaired heart rate.

I guess my anatomy prof, all the textbooks, and the related histological experiments i did myself, even the clear evidence i saw with my own eyes were wrong. Afterall... what is all that compared to some anon calling me a retard. That has convinced me.
