Are You Drinking Too
Much Coffee?

By: Royane Real
Do you take any
addictive, mind-altering drugs?
You probably would answer "no", but you if you drink tea
or coffee, you should be answering "yes"!
Many sober, law abiding people who would never dream of
knowingly ingesting a mind-altering drug, actually
consume one every day -- caffeine!
Caffeine is so pervasive in our culture and in many
other cultures that we often forget it is actually a
drug that affects our brain. Caffeine is present in
coffee, tea, many cola drinks and over the counter
medications.
The most common way that most of us ingest caffeine is
in the form of coffee. And some of us drink many cups of
coffee in a day.
If you are one of those people who drinks a lot of
coffee daily, you probably wonder what all that coffee
is doing to you. Is coffee really bad for you, or is
drinking coffee just a harmless vice? Can it be possible
that coffee is actually good for us?
The research on coffee shows mixed results. Some studies
show that drinking coffee increases the rate of heart
attacks, while other studies have shown that drinking
large amounts of coffee decreases the risk of diabetes.
There are nutritional advisers who claim that coffee
makes us age faster, wears out our adrenal glands, and
causes all sorts of untold damage to our cells.
Other researchers claim that coffee, especially if it's
freshly roasted and ground, is full of antioxidants, and
therefore good for us. Most doctors say that drinking
one or two cups of coffee a day is probably not harmful.
And of course there are others who say we ought to avoid
caffeine altogether.
The one thing that most researchers and most coffee
drinkers agree on is that coffee can keep us awake at
night and cause insomnia if we drink it late in the day.
Yet many of us drink coffee precisely because we want to
boost up the activity of our brain cells, especially
when we first wake up.
Many of us feel that we cannot really get going in the
morning until we have had our first cup of coffee. We
often continue to drink coffee throughout the day
whenever our energy appears to be flagging and our brain
seems to need additional help to think more clearly.
Does caffeine really enhance mental performance, or is
that just a myth? Yes, caffeine does give a temporary
boost to brain cells. But the amount required to improve
mental performance is not very high. Even half a cup of
coffee will be enough to give your brain a boost that
lasts several hours.
Oddly enough, more caffeine is not necessarily better.
In one test done when high-level executives were given
the equivalent of fourteen cups of coffee in a day, they
made their decisions faster, but the decisions were not
of very good quality.
Not every person reacts to caffeine in the same way.
Some people experience greater mental clarity, alertness
and productivity after a cup of coffee. Other people
become jittery, anxious, or depressed when they drink
coffee. Although caffeine will keep most of us awake if
taken at night, it does not have this effect in
everyone.
In some older people, coffee or tea can improve memory
and alertness enough to partly offset the effects of
aging.
It is true that caffeine is mildly addicting for most
people. Some people can quit using caffeine with
absolutely no withdrawal symptoms, while others will
feel headaches, fatigue, and experience cravings for
caffeine for weeks.
Caffeine works by blocking one of the
neurotransmitters--adenosine -- which normally tells
brain cells to calm down. Brain cells that have been
affected by caffeine will remain excited and on high
alert for several hours.
The most noticeable negative effect of caffeine is that
it can interfere with sleep. In most people, drinking
coffee, tea or cola in the late afternoon or in the
evening will cause insomnia.
If you are particularly affected by caffeine, you will
find that the quantity and quality of your sleep will be
greatly reduced. This can set off a vicious cycle, where
you feel so tired all the next day that you drink a lot
more coffee just to try to feel awake.
If this is happening to you, cut back on the amount of
coffee you consume each day. You may experience fewer
withdrawal symptoms if you cut down gradually. You may
wish to substitute green tea for some of your cups of
coffee. Green tea has some caffeine, but not as much as
coffee.
Better yet, consider substituting exercise for some of
those cups of coffee. If you can't leave your workplace,
at least get up from your chair periodically.
Do a few stretches, walk around a bit, and jump up and
down a few times. Take some deep breaths. A little
exercise break can revitalize your brain without giving
you the caffeine jitters.
Remember that your brain won't really benefit from more
than one or two cups of coffee in a day.
