Sound Sleep Improves Memory

A good night’s sleep helps improve memory, reveals a recent study in the US. The researchers led by Matthew Walker of Beth Israel Deaconess Medical Centre studied 12 healthy, college-going subjects and taught them a sequence of skilled finger movements similar to playing a piano scale, according to science portal EurekAlert. After a 12-hour period of wakefulness or sleep respectively, the subjects were tested on their ability to recall these finger movements while a magnetic resonance imaging (MRI) measured the activity of their brain, it said. The MRI results showed that while some areas of the brain were distinctly more active after a period of sleep, other areas were noticeably less active. But together, the changes brought about by sleep resulted in improvements in the subjects’ motor skill performance, So all studies pointing that sound sleep can improve all level perfomance in people's life.
Sound Sleep can solve all your mentally and healthy problems.

Sound Sleep Helps to prevent Diseases

A good night’s sleep and strong bonds with other people appear to help older women maintain low levels of a destructive protein linked to ailments such as osteoporosis, heart disease, Alzheimer’s and some types of cancer. As part of the normal aging process, the amount of the protein Interleukin-6 (IL-6) in the bloodstream automatically increases. Researchers found that low level of the damaging protein sank in women who managed to sleep soundly and maintain positive contact with other people and their environments in general. The study of 135 women between the ages of 61 and 90 was reported in the Proceedings of the US National Academy of Sciences in early December. However, either of the factors was sufficient to protect the women, whose average age was 73.4 years. A woman who sleeps well could make up for having a lack of friends and other positive social contacts and vice versa. The women who participated in the study submitted to numerous blood tests,gave general information about themselves and spent a night in a clinic where researchers tested their sleep patterns. The researchers plan a second study designed to determine whether high levels of IL-6 can rob older people of sleep, leaving them tired and grumpy, thereby hindering their efforts to make positive contact with other people.
