Less sleep = less memory

Even two hours less sleep per night hamper the activity of the brain

The loss of information due to lack of sleep is an irreversible process

Even two hours less sleep per night hamper the activity of the brain in perception, processing and storage of memories, according to the latest scientific data.
Insomnia and not having enough sleep have a negative impact on alertness and ability to concentrate during the day.
Providing 8 hours of sleep is actually very important for brain function and memory, scientists detected during the annual meeting of the American Society for Neuroscience.
Research at the University of Pennsylvania found that two hours less sleep per night than the recommended may impair retention of memories of the day.
It is believed that the repetition of our memories while we sleep is essential for the proper storage in the brain, says the lead researcher Ted Abel.
The loss of information due to lack of sleep is an irreversible process, the research team also found. This means that we can not recover by sleeping more on the next night.
Sleep is important because it allows the brain to carry out tasks for which it is too busy during the day. While we sleep and rest, the brain records information, explains Neil Stanley, a leading British expert on sleep.
According to another study, published in the journal PLOS One, falling asleep shortly after receiving new information increases the chance to assimilate it successfully.
Scientists from the University of Notre Dame in Indiana believe that the best time for a final exam preparation or professional presentation is precisely little before bedtime.
