A couple of “Dr’s” did some digging and couldn’t find a study that proved drinking 8 glasses of water a day contributes to human health – despite finding claims that “People in hot, dry climates and athletes have an increased need for water, and people with certain diseases do better with increased fluid intake”
Did they report, why these people needed water in the first place? No. Just that healthy people don’t need 8 glasses because there wasn’t a study that named 8 as the golden number.
Liquid H2O is the sine qua non of life. Making up about 66 percent of the human body, water runs through the blood, inhabits the cells, and lurks in the spaces between. At every moment water escapes the body through sweat, urination, defecation or exhaled breath, among other routes. Replacing these lost stores is essential to rehydration. (Scientific American)
The human body needs water to maintain enough blood and other fluids to maintain proper functioning organs (Kidneys, lungs, liver, skin etc.). Dehydration can result from loss of water and mild to severe results are (some of which we all have experienced from the lack of water intake from a night of drinking – which has been scientifically proved to dehydrate humans) (Rehydration Project):
# cannot pass urine or reduced amounts, dark, yellow
# cramping in the arms and legs
# weakness
# low blood pressure
# fainting
# convulsions
# a bloated stomach
# heart failure
# sunken fontanelle – soft spot on a infants head
# sunken dry eyes, with few or no tears
# skin loses its firmness and looks wrinkled
# lack of elasticity of the skin (when a bit of skin lifted up stays folded and takes a long time to go back to its normal position)
# rapid and deep breathing – faster than normal
# fast, weak pulse
Severe:
# hypovolaemic shock
# diminished consciousness
# cool moist extremities
# a rapid and feeble pulse
# low or undetectable blood pressure
# eripheral cyanosis
# And ultimately Death.
These Dr’s whole premise seems to be around this:
“For average healthy people, more water does not seem to mean better health”
Hello. Asshole. This is completely subjective. What’s “average”? What’s “healthy”? How do people get “healthy”? Did drinking water contribute to that “average healthiness”?
Their proof is not that they scientifically disproved the benefits of water (8 glasses a day), is that they could not find scientific research to back these claims.
I would bet that the claim for 8 glasses of water is from a law of averages. Every person is different, some may need 6 some 9 glasses a day. That intake is assumed in not just glasses of water but in the food, soda, fruit and other sources of nourishment that also contain water. An 8 glass a day regiment ensures hydration and avoidance of the symptoms mentioned above.
To announce that not drinking 8 glasses of water a day is not beneficial WITHOUT scientific research to back up this claim is simply irresponsible.
These Dr’s are either very bad at correlating research to justify/disprove this claim, very poor researchers in general, or just making a claim to make a name for themselves in the news… Your call but I have to go piss all over this now that I’ve finished my 6th glass this morning.
