Sleep And Cognitive Decline: Is Quality More Important Than Quantity?

Sleep is crucial for a variety of reasons, but researchers have cautioned that too much sleep might be detrimental to your brain’s health.

According to official NHS recommendations, most individuals require between six and nine hours of sleeping each night.

New research, though, has revealed that this may not be the truth, with some individuals reporting that they need as little as four hours sleeping a night to keep it fresh when they wake up.

It has been discovered via research conducted by professionals in the United States capital of Washington that getting too much sleep might really impair your cognitive performance.

Cognitive decline was shown to be more common in persons who slept fewer than 4.5 hours per night and in individuals who sleep over than 6.5 hours every night, according to the experts.

It’s important to note that all of these people reported having difficulty getting good quality sleep.

Sleep and cognitive deterioration

Researchers discovered that the influence of sleep length on the brain was the same as the effect of aging, one of the most significant risk factors for the development of illnesses such as Alzheimer’s.

According to the study, people should sleep between 4.5 and 6.5 hours every night, depending on their needs.
6.5 hours of sleep each night was shown to be connected with cognitive deterioration over time, which is low when considering that older persons should obtain approximately seven to eight hours of sleep per night, according to the study’s findings.
It’s possible that when it comes to the risk of acquiring dementia, it’s not always the duration of sleep that counts, but rather the quality of that sleep.
Scientists, on the other hand, stressed that it’s important to recall that the 100 people in the research who slept for a longer period of time may have been suffering from illnesses that were not detected by the tests.
