Neurologists warn that daytime sleep is associated with dementia (acquired dementia, the disintegration of mental functions that occurs as a result of brain damage). Too frequent daytime sleep or prolonged sleep at night (more than 9 hours) can lead to dementia and brain damage. The greatest influence of daytime sleep has on the body of mature women, who lie down to rest after physical exertion. But French scientists who conducted research involving more than 5000 years, sounded the alarm.
Every fifth person who slept regularly after lunch had low rates of intellectual tests. The results of the study show that excessive daytime drowsiness can be an early predictor of cognitive impairment. In another study, it was found that people who slept more than nine hours a day, but less than five, had a decrease in mental ability. That is, these data indicate the manifestation of the initial stage of Alzheimer's disease, which is the most common form of dementia.
There are also several evidences linking the length of sleep and disorders leading to cardiovascular diseases and diabetes, so it is not surprising that, in addition, prolonged and daytime sleep affects the cognitive abilities of people. In this regard, it was recommended to sleep about seven hours a day.
