Many teenagers who love the energy drinks that contain caffeine . Ads energy drinks and coffee also seemed to target the youth as their target market . Research
in Europe shows that the average caffeine consumption by children and
adolescents has increased more than 70 percent in the last 30 years . Highest growth was recorded in the industrial segment of caffeinated energy drinks . This raises the question of whether caffeine consumption by children and adolescents is actually safe ?Research
conducted by the University Children's Hospital Zurich have shown that
caffeine can hinder brain development in children and adolescents , but
new evidence is found in animal experiments .
Studies in ratsThe research team led by Reto Huber gave a moderate dose of caffeine for 5 days to a couple of adolescent rats aged 30 days . The dose equivalent to 3-4 cups of coffee per day in humans . Number of rats in the control group received only fresh water . Then , the brain waves in the animals studied .Young rats given caffeine are less likely to sleep so that they obstructed the process of brain maturation . Lack of sleep is characterized by a slow their brain waves until a week after the last caffeine administration . In
addition, the neural connections in the brains of rats was much higher
than in the brains of rats that received only fresh water . It shows that they are experiencing slower maturation . They
look much more silent , shy and cautious , while the rats that were
given fresh water is more active and show curiosity - general features
in the mice that had grown ."The brain is very plastic kids because a lot of connections , " said Reto Huber , lead author of the study. In
a process called synaptic pruning ( synaptic pruning ) , these
connections will eventually disappear or consolidated during puberty . Connections
between the brain's nerve extended , shortened , cut and summarized so
that the brain tissue becomes more efficient and more powerful . This optimization process may occur during deep sleep .Although
there is clearly a difference between the brain of rat and human brain ,
the researchers say that both neurodevelopmental and that further
research in humans is needed .
The importance of getting enough sleepExperts have long advised teens to sleep at least nine hours every day . Lack
of sleep can restrict the ability of youth to concentrate , learn,
remember , and make them irritable or tend to eat unhealthy . Of this research note that lack of sleep may also inhibit brain maturation in adolescents .
