Assuming you don't have a genitourinary tract infection, fresh urine should be sterile, the problem is that it is a waste product which, apart from making it not taste very nice, means that consuming it will increase the concentration of waste in your body which will require an increased volume of water to absorb and subsequently excrete, resulting in you ...

Copy and paste from the answer here: http://skeptics.stackexchange.com/questions/1540/is-it-a-good-idea-to-drink-your-own-urine-in-a-survival-situation Summary: You can do it, as a last resort, but it's dicey. The US Army doesn't think it's a good idea and lists it on its "Do NOT drink" list, stating in its Field Manual that it "contains harmful body ...

Urine is normally sterile (barring urinary tract infections) - so, from bacteriological stance, fresh urine isn't going to hurt. The problem is - urine is a waste product, and so is full of stuff that your body wants to be rid of. Worse, as you get more dehydrated, your body produces more concentrated urine. That said - as a short term measure to keep ...

The idea that caffeinated drinks dehydrate you or "don't count" toward your body's water requirement is a myth. Laboratory studies have shown that caffeinated soda is just as hydrating as water, i.e., the diuretic effect of the caffeine is too small to measure.[Grandjean 2000] Even in the case of coffee, which has much higher concentrations of caffeine than ...

Tree's generate water as part of the respiration process (not to be confused with photosynthesis which is different). This happens at night and day. This is relatively static day or night. Photosynthesis alters dependant on sunlight, respiration (being the process of producing energy) does not. Respiration will alter dependant on the time of year, i.e. ...

There are two types of water-based concerns while doing strenuous activity in the desert: dehydration and hyponatremia. Dehydration occurs when your body is not getting enough water, and is the most common. Symptoms include irritability, headache, lack of energy, bright yellow/orange and infrequent urine. You lose water while you sweat, but in hot climates ...

Given that your water is clean I don't think cleaning the bottle is a major concern. Personally I would rinse a water bottle out with tap water before filling (or maybe once a day if using it lots) and only bother with soap if visibly dirty. Therefore I would say your suggestion is more than necessary but not excessive. For reference I fill my water bottle ...

One of the big differentiators in the past between hard and soft bottles was that soft bottles would absorb some of the flavor from drinks. I'm not sure how much that affects soft bottles on the market today. In contrast to what @JustinC said, I believe hard bottles are more likely to explode. Due to their rigidity they will hold their shape until the ...

I look at soft plastic drinking bottles as a great but slightly risky way to trim weight. Soft plastic should always be lighter than hard plastic, even if the difference is minor. The same applies to thin metal bottles which have the same benefits as hard plastic. The risk is in the ability of the soft plastic to either puncture or explode under pressure. ...

Your blood and body need sodium, potassium and various other solutes in order to function (without the correct potassium levels, your heart will start to fail etc) In a hot country, where you may sweat a lot, and top up your liquids by drinking water, you lose these solutes quite rapidly. The quantities you require are generally a lot higher than you might ...

As long as the water you are filling it with is clean, it won't be the problem. What may cause an issue is your mouth. Human mouths are not especially clean, and while microorganisms are kept at bay in the mouth, they can start to multiply rapidly in water. I always recommend washing bottles once a day. As a simple, convenient and quick hygiene step it ...

If your water source is clean and assuming you are a relatively clean person in a fairly clean environment (not working in sanitation), You can probably get away with never cleaning it and not get sick. Tap water usually has some chlorine in it to keep basic bacteria and virus levels low. So refilling it with this water will keep the general levels low ...

I'll weigh in on the Gatorade part. No, you don't need Gatorade, or any other drink with the right salts in it. However, you do need to replace the salts somehow. I use Gatorade because it's convenient (I have to carry the water anyway), the amount of electrolytes I need to replace is well matched to the amount of water I need to replace so having them in ...

One benefit to a soft bottle over a hard bottle is: You can compress a soft bottle as you drink from it to reduce the sloshing of water in the bottle as you walk.

Cleaning once a week may be slightly more than enough, but it is reasonable. Depending on your environment, there may be factors that cause the bottle to smell bad. Something I have learned from biking is to store the empty bottle in the freezer at night, or when not in use. Freezing kills a lot of things and prevents growth of mold/mildew. It has the ...

More important than the cleaning is, in my opinion the choice of the bootle. I switched to a bottle explicitly designed for a use like yours, in my case a Nalgene drinking bottle. My reasons for doing so: Health concerns: While I think there are regulations about what materials are allowed in drinking bottles, they have shown to be insufficient in many ...

So-called "sports drinks" such as Gatorade are miracles of modern marketing, surpassed only by bottled water. They are expensive and contain large amounts of sugar. If you're hiking long distances in high temperatures (say 40 C or 105 F), then you have a long list of hazards to worry about, one of which is getting low on electrolytes. Higher on the list ...
