Caffeine - Should You Be Giving it Up?
Caffeine - Should You Be Giving it Up?
By Royane RealCaffeine is so pervasive in
our culture and in many other cultures that we often forget it is
literally a drug that affects our brain. Caffeine is present in coffee,
tea, many cola drinks and over the counter medications.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 literally a drug that affects our brain. Caffeine is present in
coffee, tea, many cola drinks and over the counter medications.
The
real question is—is caffeine a bad drug, or is it “okay”? Is caffeine
even better than “okay”, does it do good things for us?
The
verdict on caffeine, particularly when taken in the form of coffee,
seems to be mixed. 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. 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 use it 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 productivy after a cup of coffee. Others become jittery,
anxious, or depressed. 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. The quantity and quality of sleep will
be greatly reduced, setting in motion a vicious cycle, where the person
affected will feel so tired all the next day that he drinks a lot more
coffee in order to try feel awake.
If this is happening to you,
cut back on the amount of caffeine 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.This article is taken from the new book
