Researchers from Harvard Medical School in Boston found that deep sleep to provide special reflective brain impulses that block the sound, not allowing them to sleep consciousness.And people who have such impulses more sleep heroic sleep and get up in the morning refreshed and full of energy.
The researchers conducted an experiment on 12 volunteers who were tortured for three nights in a row.The first night was relatively calm, and the scientists measured the number of pulses in volunteers.Later, these waves have been na
Two nights later the volunteers sleep disturbed.Once entered into the dormant phase of REM sleep, they began to disturb the different sounds: included recording the noise of cars, airplanes, telephone calls, calls and so on.Ten second sound starts with the intensity of 40 decibels (muffled conversation), and grew up as long as there were no signs of awakening.One group of subjects at the same time there is a high activity of the brain, which send impulses reflecting.Others, on the contrary, noise filters, spindles were less so, this group of volunteers woke up more often.
now head of the laboratory, which conducted the study, professor of neurology Jeffrey Ellenbogen tries to understand how exactly does this lock, and whether you can call it artificially.For insomnia due to noise - the main reason for patients references to a sleep.
This has been proved that good night's sleep - is the key not only to the beauty, health and good mood, but also an excellent memory.So, a few years ago, American researchers came to the conclusion that the Earth inhabitants do not sleep to rest their brains, and then that he was able to process and store the resulting information for the day.Accordingly, the more information, the need to sleep longer and longer and the better you sleep, the better the memory.
