The brain also matures fastest in this period. But when pubescent rats are administered caffeine, the maturing processes in their brains are delayed.[/B] Children's and young adults' average caffeine consumption has increased by more than 70 per cent over the past 30 years, and an end to this rise is not in sight: the drinks industry is posting its fastest-growing sales in the segment of caffeine-laden energy drinks. Not everybody is pleased about this development. Some people are worried about possible health risks caused in young consumers by the pick-me-up. Researchers led by Reto Huber of the University Children's Hospital Zurich are now adding new arguments to the debate. In their recently published study conducted on rats, the conclusions call for caution: in pubescent rodents, caffeine intake equating to three to four cups of coffee per day in humans results in reduced deep sleep and a delayed brain development. [B]Peak level during puberty[/B] Both in humans and in rats, the duration and intensity of deep sleep as well as the number of synapses or connections in the brain increase during childhood, reaching their highest level during puberty and dropping again in adult age. "The brain of children is extremely plastic due to the many connections," says Huber. When the brain then begins to mature during puberty, a large number of these connections are lost. "This optimisation presumably occurs during deep sleep. Key synapses extend, others are reduced; this makes the network more efficient and the brain more powerful," says Huber. [B]Timid instead of curious[/B] Huber's group of researchers administered moderate quantities of caffeine to 30-day-old rats over five days and measured the electrical current generated by their brains. The deep sleep periods, which are characterised by slow waves, were reduced from day 31 until day 42, i.e. well beyond the end of administering caffeine. Compared to the rats being given pure drinking water, the researchers found far more neural connections in the brains of the caffeine-drinking animals at the end of the study. The slower maturing process in the brain also had an impact on behaviour: rats normally become more curious with age, but the rats consuming caffeine remained timid and cautious. The brain goes through a delicate maturing phase in puberty, during which many mental diseases can break out. And even if the rat brain differs clearly from that of humans, the many parallels in how the brains develop raise the question as to whether children's and young adults' caffeine intake really is harmless or whether it might be wiser to abstain from consuming the pick-me-up. "There is still need for research in this area," says Huber.[/QUOTE] Damn, suddenly I don't want to drink coffee anymore.

In my experience 90% of teenagers have fast enough metabolisms to be able to start their morning without caffeine.
I opened this thread JUST as I finished my 24 ounce coffee. FUCK.

Never understood why people <17 years old would want/need to drink coffee daily.

Sure, it speeds up but if they already had a slow metabolism it doesn't get that much faster. Besides the stress that growth puts on your body is not exhausting but noticeable tiring, meaning people want to sleep. A lot.
caffeine isn't only in coffee, its also in soft drinks, as the article mentions. Dont know why people are only mentioning coffee.
Glad I'm not a rat!
Humans have been drinking coffee for 600 years while rats have not. I think there's a difference in caffeine tolerance here.
[QUOTE=Lethaxx;42294307]caffeine isn't only in coffee, its also in soft drinks, as the article mentions. Dont know why people are only mentioning coffee.[/QUOTE] For one, coffee is more well known. For another, it has more caffeine than many soft drinks. I drink coffee literally every single day where as only drink 3-4 soft drinks a week.
Replicate this in monkeys and I'll take notice.
[QUOTE=spiritlol;42294358]Humans have been drinking coffee for 600 years while rats have not. I think there's a difference in caffeine tolerance here.[/QUOTE] 600 years is far to little time to build a "tolerance". Tolerance itself is per individual basis, there's nothing genetic about it. It would only be in our genes if it improved our fitness (not in a body building sense, but to our environment) thus increasing our chance of spreading our genes. If it doesn't help nor kill us, evolution is indifferent. No change would be made. On the contrary I would argue that rats have been eating coffee beans longer than we have, since it is a part of their natural environment (not all rats of course, but the rodents that live around the areas that grow these beans).
[QUOTE=FPSMango;42294255]Never understood why people <17 years old would want/need to drink coffee daily.[/QUOTE] Because (American) school require us to do way too much homework, and we can't go to bed at a healthy time.
We Scandinavians need our coffee [IMG]http://i.imgur.com/HbnzLQW.png[/IMG] I blame the cold and the dark during Winter
Holy shit, we're not #1 at something? [editline]24th September 2013[/editline] Or even top 15?!
[QUOTE=FPSMango;42294255]Never understood why people <17 years old would want/need to drink coffee daily.[/QUOTE] Coffee is actually nice and people like the ability to stay alert for longer periods of time? I certainly find it helps.

[QUOTE=spiritlol;42294358]Humans have been drinking coffee for 600 years while rats have not. I think there's a difference in caffeine tolerance here.[/QUOTE] Its like none of you are reading the article Its saying high caffeine usage can slow development in kids and young teens, which seems kind of obvious. Its also why the alcohol limit in the US is 21 years old, because its not until that point that your liver is fully developed.
lol keep eating your shit food you ignorant fucks I hope you all get cancer and die from over-ingestion of the shitty chemicals you love to defend. 420 blaze it fags [highlight](User was banned for this post ("Flaming / shitposting / meme reply ... 3 times in 2 weeks.

Ban soda until age 21.

[QUOTE=wraithcat;42294883]A lot of teens tend to abuse energy drinks though, which contain more caffeine than coffee.[/QUOTE] There was an article in my local paper last year that talked about a teen girl (15 or 16) who actually died by drinking seven cans of those large Monster Energy Drinks in just a few hours time.

Quitting cold turkey is impossible, having tried it at least 6 times. The migraines of going without for a while are just unbearable and I envy you not being addicted.

It's also hugely a social thing, as well as placebo, and once your body gets used to daily caffeine dose (which removes all the positive effects of it, by the way), getting it no more makes you feel like [I]shit[/I] - it's pretty much legitimate withdrawal effects. A cup of something hot in the morning is always nice, too.
