The scientists have cautioned teens from drinking coffee. Coffee drinking has emerged as a debatable subject in the recent past with many studies highlighting its adverse effect in humans.
A new study on mice suggests, drinking three to four cups of coffee per day may delay brain development in teenagers
Researchers at the University Children’s Hospital Zurich found when pubescent rats were administered caffeine, the maturing processes in their brains delayed.
The scientists say, 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.
When the brain then begins to mature during puberty, a large number of these connections are lost, he adds.
Huber’s group of researchers administered moderate quantities of caffeine to
The 30-day-old rodents were administered with caffeine equating to three to four cups of coffee per day in humans for over five days. The scientists measured the electrical current generated by their brains. This process resulted in reduced deep sleep and a delayed brain development.
The deep sleep periods, which are characterized by slow waves, were reduced from day 31 until day 42, i.e. well beyond the end of administering caffeine.
