Sleep sound at night or a time will come when your brain let you sleep forever. Evidence has made it proved that poor sleep patterns can make you cranky. The four new studies suggest that amount and quality of sleep one must have to take is necessary or otherwise it will lead mental deterioration and Alzheimer’s disease.
Too little or too much sleep was equated with two years brain aging in one study. A separate study concluded that people with sleep apnea, disrupted breathing during sleep, were more than twice as likely to develop mild thinking problems or dementia compared to problem free sleepers.
Yet another suggests that enormous daytime sleepiness may predict dwindled memory and thinking skills, known as cognitive decline that particularly happens with older people.
The one main study ,which examined data on more than 15,000 women in the U.S.Nurses Health Study which followed the women over 14 years beginning in middle age , suggest that those who slept five hours a day or less or nine hours a day or more had average mental malfunctioning than participants who slept seven hours per day. Too much or too little sleep is somewhat directly proportional to mental malfunctioning or was cognitively equivalent to aging by two years.
The study also suggests that women whose sleep duration changed by two hours or more a day from mid to later life had worse brain function than participants with no change in sleep duration.
According to Heather Snyder, senior associate director of medical and scientific relations for the Alzheimer’s Association in Chicago, who was not involved in research thoughtfully, said that whether sleep changes are the signs of a decline to come or the cause of decline is something we don’t know , but these four studies enlightened that this area need to look more.
