It is certainly true that drinking adequate water is very important
for overall health. However, there is no credible evidence to suggest
that drinking water at certain times of the day will provide the
particular health benefits specified in this message. Staying well
hydrated can help maintain overall health and may thereby help avoid
serious health outcomes such as heart attacks and stroke. But, this is
true at any time of the day. The supposed cardiologist is not named
and the message contains no references. And the information did not
come from the Mayo Clinic as claimed in some versions of the message.

Subject: Fw: When to Drink Water - From a Cardiac SpecialistCorrect
Time to Drink Water....Very Important.This is interesting!! I knew you
need your minimum water to flush the toxins out of your body, but this
was news to me.Correct Time to Drink Water....Very ImportantFrom A
Cardiac Specialist!
Drinking water at certain time maximizes its effectiveness on the body:
2 glasses of water after waking up - helps activate internal organs1
glass of water 30 minutes before a meal - helps digestion1 glass of
water before taking a bath - helps lower blood pressure1 glass of
water before going to bed - avoids stroke or heart attack
Please pass this to the people you care about......Detailed
AnalysisAccording to a "health tip" that circulates via email, the
blogosphere and social media outlets, drinking water at certain times
of the day can maximize the water's effectiveness and provide very
specific and immediate health benefits. According to the message,
drinking water after waking up helps activate internal organs,
drinking water before meals aids digestion, and drinking water before
a bath lowers blood pressure. The message further claims that by
drinking water before bed people can avoid heart attacks and strokes.
Supposedly the information comes courtesy of a cardiac specialist.Of
course, water is vital for our health and ensuring that we drink
enough water to stay well hydrated can certainly have important and
ongoing health benefits. However, there is no credible evidence to
support the claims that drinking water at certain times of the day
will lead to the specific health outcomes outlined in the message. I
discuss each of the message's claims in turn below:Claim - "2 glasses
of water after waking up - helps activate internal organs":This claim
is virtually meaningless. What specific internal organs is it
referring to? And one would hope that our organs continue to be active
even when we sleep. If not, then a glass of water is unlikely to help
us. Given that, after waking, we might not have had liquids for
several hours, drinking water early in the morning may help rehydrate
us and make us feel better. As at any other time of the day, drinking
adequate water in the morning may contribute to overall good health.
But, drinking water when we wake up is certainly not required to
"activate" our internal organs. That claim is just silly.Claim - 1
glass of water 30 minutes before a meal - helps digestionDrinking a
glass of water 30 minutes before a meal is unlikely to have much
effect at all on digestion. Water passes through your system quite
quickly, so it is doubtful that one glass of water 30 minutes before
eating would still be around in enough quantities and at the required
point in the food digestion process to be of any significant help. In
fact, even when water is taken with the meal itself, its impact on
digestion is not likely to be very significant. Moreover, unless you
have specific health problems or have a very poor diet, your body is
likely to do a terrific job of digesting your food without any water
at all. An article about the issue onboston.com notes:
Dr. Braden Kuo, director of the GI Motility Lab at Massachusetts
General Hospital, says that drinking water is not necessary for
digesting food, because the body is very efficient at secreting and
reabsorbing its own fluids. At the first stage of digestion, drinking
water can simply make it easier to swallow food, since most of us have
difficulty swallowing when our food is not sufficiently moistened with
saliva.When the food reaches the stomach, water "may help to some
degree, but its impact is moderate to minimal,'' he says. He adds that
having some extra fluid in the mix may help smooth the digestive
process for those with constipation.Ironically, another spurious
Internet health tip falsely claims that drinking water after a meal
can cause cancer.Claim - 1 glass of water before taking a bath - helps
lower blood pressureDrinking water before a bath - or at any other
time for that matter - does NOT lower blood pressure. Biomedical
researcher Judith Airey, PHD notes:So the bottom line is that,
generally, increasing the amount of water that is consumed will not
increase the amount of sodium lost by the blood, so blood pressure
will not be lowered.In fact, drinking water can actually cause a very
short term increase in blood pressure in some people, particularly
those with some types of very low blood pressure. This is only
temporary and has no long term impact on blood pressure.Keeping
hydrated is good for health, but overhydration has no benefit for
lowering blood pressure.Water spalshing into glass

that water can raise rather than lower blood pressure. A Vanderbilt
University Medical Center newsletter article explains:Researchers at
Vanderbilt University Medical Center have shown that ordinary water --
without any additives -- does more than just quench thirst. It has
some other unexpected, physiological effects. It increases the
activity of the sympathetic -- fight or flight -- nervous system,
which raises alertness, blood pressure and energy expenditure.David
Robertson, M.D., and colleagues first observed water's curious ability
to increase blood pressure about 10 years ago, in patients who had
lost their baroreflexes -- the system that keeps blood pressure within
a normal range.Moreover, unless you have significant problems with
hypertension, why would it be necessary to lower your blood pressure
before having an ordinary bath? In fact, soaking in a hot tub may
actually lower the blood pressure of healthy people. So, it is
difficult to see any health benefit at all in lowering your blood
pressure before having a bath. Given that a hot bath might lower your
pressure anyway, taking steps that cause your blood pressure to go
even lower might actually have negative health impacts for some
people. And, in an article titled "Hot Tub and Sauna Use and High
Blood Pressure", the American Heart Association notes:Hot tubs and
saunas pose no risk to healthy people as long as they are not misused.
People with high blood pressure should tolerate saunas well as long as
they are not experiencing a hypertensive crisis.
Claim - 1 glass of water before going to bed - avoids stroke or heart
attackAh, if only life was so simple. Of all the claims in the
message, this is the most nonsensical. If preventing strokes and heart
attacks were as simple as drinking water before bed, those duel
killers and maimers would be pretty much a thing of the past. The
supposed remedy is not listed on any credible heart or stroke
prevention website. The claim is inaccurate and misleading. Drinking a
glass of water before going to bed certainly will not prevent a heart
attack or stroke.But, again, drinking water and staying well hydrated
throughout the day can help keep you healthier and perhaps therefore
make it a little less likely that you will have a heart attack or
stroke. The American Heart Association notes:
Keeping the body hydrated helps the heart more easily pump blood
through the blood vessels to the muscles. And, it helps the muscles
remove waste so that they can work efficiently."If you're well
hydrated, your heart doesn't have to work as hard," said John Batson,
M.D, a sports medicine physician with Lowcountry Spine & Sport in
Hilton Head Island, S.C., and an American Heart Association
volunteer.Dehydration can be a serious condition that can lead to
problems ranging from swollen feet or a headache to life-threatening
illnesses such as heat stroke.The message claims the the information
comes from a cardiac specialist.. However, the alleged specialist is
not identified. Nor does the message reference any credible medical
sources to support its claims. The message is reminiscent of other
spurious health tips that circulate via email including one that
claims that an unnamed cardiologist has recommended a dubious
technique known as cough CPR.Another, longer, version of the message
falsely claims that the information came from the Mayo Clinic and
includes misleading and potentially harmful advice about the use of
aspirin and heart attacks.Thus, this would-be health advisory doesn't
hold water, so to speak. If we wish to stay healthy, it is important
that we stay adequately hydrated and drinking plain old water is one
of the best ways to achieve this. But, keeping hydrated is an ongoing
task that is dependent on various factors such as the current
temperature, what exercise we are doing and our overall health.
Drinking water at certain times of the day will not provide the
specific health benefits outlined in the message.Bookmark and
