The duration of night rest from 7 to 8 hours is ideal because if it is less, it can provoke the formation of deadly plaques in the brain. And excess sleep in old age makes a person more retarded and forgetful.

Researchers from Stanford University have once again confirmed the long-known axiom that a person should get at least 7-8 hours of sleep at night. This is especially important for the elderly, as adequate night’s rest preserves brain health. If people slept less than 6 hours, their cognitive functions deteriorated, and the level of dangerous plaques associated with senile dementia increased in the brain.
People who slept too much showed poorer memory and slower response, despite the lack of high levels of beta-amyloid proteins in the brain. The researchers analyzed the brain function of 4,500 people with an average age of 71 from the United States, Canada, Australia, and Japan.
Independent experts believe that the data obtained confirm the already known links between the accumulation of beta-amyloid protein and the deterioration of cognitive activity. As for sleeping too long in old age, it can be a symptom of some other health problems, such as depression.
