This can lead to seizures, involving involuntary muscle movements and loss of consciousness.

Caffeine ingestion and fluid balance: a review.

Now that’s a stroke of genius. The refractive index of liquid water (1.333 at 20°C (68°F)) is much higher than that of air (1.0), similar to those of alkanes and ethanol, but lower than those of glycerol (1.473), benzene (1.501), carbon disulfide (1.627), and common types of glass (1.4 to 1.6). The refraction index of ice (1.31) is lower than that of liquid water. Urinary tract infections (UTIs) are the second most common type of infection in the body. They account for around 8.1 million visits to health care providers in the U.S. every year. In November 2014, the American College of Physicians issued new guidelines for people who have previously developed kidney stones. The guidelines state that increasing fluid intake to enable 2 liters of urination a day could decrease the risk of stone recurrence by at least half with no side effects.

Another report describes the development of hyponatremia after drinking more than 5 liters in a few hours.This would be around 15.5 cups for men and just over 11 cups for women. However, around 80 percent of this should come from drinks, including water, and the rest will be from food. One factor in estimating when water appeared on Earth is that water is continually being lost to space. H 2O molecules in the atmosphere are broken up by photolysis, and the resulting free hydrogen atoms can sometimes escape Earth's gravitational pull (see: Atmospheric escape). When the Earth was younger and less massive, water would have been lost to space more easily. Lighter elements like hydrogen and helium are expected to leak from the atmosphere continually, but isotopic ratios of heavier noble gases in the modern atmosphere suggest that even the heavier elements in the early atmosphere were subject to significant losses. [29] In particular, xenon is useful for calculations of water loss over time. Not only is it a noble gas (and therefore is not removed from the atmosphere through chemical reactions with other elements), but comparisons between the abundances of its nine stable isotopes in the modern atmosphere reveal that the Earth lost at least one ocean of water early in its history, between the Hadean and Archean eons.

Yamashiro, M., et al. (2013). A case of water intoxication with prolonged hyponatremia caused by excessive water drinking and secondary SIADH. To avoid hyponatremia, it is important not to outpace the kidneys by drinking more water than they can eliminate. Untreated, chronic kidney disease can lead to kidney failure. The organs stop working, and either dialysis or kidney transplantation is required.Dehydration happens if we use and lose more water than the body takes in. It can lead to an imbalance in the body’s electrolytes. Electrolytes, such as potassium, phosphate, and sodium, help carry electrical signals between cells. The kidneys keep the levels of electrolytes in the body stable when they function properly.

Tesco’s move to sell tinned water comes in the week after Iceland became the first supermarket in the UK to sell plastic-free chewing gum – making it from tree sap instead. http://articles.chicagotribune.com/2013-06-05/health/ct-x-0605-drinking-water-20130605_1_dietary-guidelines-much-water-drinking-water

The amount of water needed each day varies from person to person, depending on how active they are, how much they sweat, and so on. Joo, M. A., & Kim, E. Y. (2013). Hyponatremia caused by excessive intake of water as a form of child abuse.
