Green tea, black tea and coffee have
been long known as energy boosters. They were used in order to revitalize the
body and mind when they were giving signs of tiredness. Nowadays, many people
rely on these energy increasers to give them power to make it through the day.
The day of a modern person starts with a large cup of coffee, while during the
day, at least one cup of black or green tea are drank to maintain the level of
energy as high as possible. Also, the recent history has also come up with
numerous energetic drinks and sodas which are very rich in caffeine and which
are highly popular among people who want to increase their brain power or
muscular strength for a limited period of time.
The miraculous ingredient which makes
all these drinks highly effective in fighting sleep and tiredness and boosting
the energy is caffeine. People heavily rely on it for solving all their tasks
in a limited period of time and with minimum physical effort. It has become as
used as all the other basic foods and drinks.
The reason for which caffeine is so
effective is that it affects the release of adenosine, the chemical substance
meant to announce the body when it is time to sleep. Without this chemical or
when its presence in the body is significantly reduced, the body does not feel
the need to sleep, thus prolonging its state of alert. Also, because caffeine
fully oxygenizes the brain and reduces the flow of blood which reaches the
heart, the brain gets more and more active and energetic, which leads to an
increased intellectual activity. This is the reason for which most people
signal a higher power of leaning and greater intellectual capacity after
consuming a cup of drink containing this wonder-ingredient.
Yet, in addition to firing up the
neurons and increasing the intellectual abilities for a limited period of time,
the drinks containing caffeine also give the individual a state of well-being.
This state is caused by the dopamine, the same substance which is responsible
for creating addiction. Thus, if you drink caffeine drinks on a regular basis
and you feel like you lose your focus when you do not have a cup of coffee in
the morning, you should know that the only one to blame for that is the
dopamine.
