It’s the question that everyone seems to ask. And if you follow the
standard advice (drink 8 to 10 glasses of water every day), your next
request will be for directions to the restroom. Because unless you’re a
strenuous exercise or a desert dweller, you’re unlikely to need that
much water—and unless you’re carrying a horse’s bladder, you won’t hold
onto it for long.
No one’s quite sure where the 8-to-10 glasses factoid started. However,
medical professionals do agree on quite a few things about fluids:
• Six glasses is usually enough. If you must count, 6 glasses of water a
day is probably a good rule of thumb (not a bare minimum). But the
average person, doing gentle activity in a gentle climate, can probably
get all the fluid they need from solid food alone (although it’s not
recommended).
• Follow your thirst. Your need for water varies greatly depending on
your activity level. Fortunately, your body is surprisingly good at
telling you when to drink. And the idea that we’re chronically (and
unknowingly) dehydrated is little more than science fiction.
• Don’t fear coffee and tea. Despite the diuretic properties of
caffeine, you’ll still retain a large amount of the fluid in every
cup—and even more if you’re a regular drinker of caffeinated beverages.
• Dehydration may worsen constipation. If you’re straining to pass
stool, you might benefit from increasing your water intake a bit.
However, results vary, and a more likely cause of constipation is
inadequate fiber in your diet.
So why are we so easily misled by drinking myths that don’t hold water?
Quite simply, in the era of modern science, we’re used to hearing (and
accepting) startling facts. But when it comes to water, medical research
is in an unusual position: proving that our common sense was right all
along.

Recent research suggests that water is an essential component of the
human body. It helps in maintaining the balance of the body. Therefore
if drank correctly it works miraculously in the process of loosing
weight. Water increases the metabolism rate of the human body and helps
in weight loss. Drink a glass of hot lemon water in the morning, this
helps in loosing weight three times faster than simple exercising and
thus helps to burn out large amount of calories from body. Consuming
lots of water, fills up the stomach, thus it reduces appetite and cuts
down on food intake. Water also helps in cleaning the body parts, by
flushing out waste with the help of kidney.
