experts found that people who slept less than 4.5 hours a night, and those who slept more than 6.5 hours each night had a greater risk of cognitive decline over time.<\/p>\n<p>It\u2019s key to note that all of these participants also struggled with poor quality sleep.<\/p>\n<p>They also found that the impact of sleep duration on the brain had the same effect as aging \u2013 which is one of the biggest risk factors when it comes to developing conditions such as\u00a0Alzheimer\u2019s.<\/p>\n<p>The researchers suggest that for adults, sleeping between 4.5 and 6.5 hours a night is ideal.<\/p>\n<p>Writing in\u00a0<a

brain flush out harmful proteins that build up during the day.<\/p>\n<p>\u201cSo interfering with sleep might interfere with our brain\u2019s ability to get rid of these.<\/p>\n<aside class=\"single__inline-module alignright\">\n\t<\/aside>\n<p>\u201cExperimental evidence even supports this \u2013 showing that even just\u00a0one night of sleep deprivation\u00a0temporarily increases beta-amyloid levels in the brain of healthy people.\u201d<\/p>\n<p>He added that the findings of the Washington study are surprising, as most health bodies, including the NHS in the UK and the Centre for Disease Control (CDC) in the US, all state that people should be having more than six hours each night.<\/p>\n<p>\u201cThe study showed that sleeping longer than 6.5 hours was associated with cognitive decline over time \u2013 this is low when we consider that older adults are recommended to get between\u00a0seven and eight hours\u00a0of sleep every night.<\/p>\n<p>\u201cIt could be the case that it isn\u2019t necessarily the length of the sleep that matters, but the quality of that sleep when it comes to risk of developing dementia\u201d, he said.<\/p>\n<p>He did however state that it\u2019s key to remember that the 100 participants in the study who slept for longer may have been suffering with issues that were not picked up on the tests.<\/p>\n<figure class=\"wp-block-image

hours was associated with cognitive decline over time.<\/figcaption><figcaption><span class=\"credit\">Getty Images<\/span><\/figcaption><\/figure>\n<p>The researchers had adjusted for dementia-related factors but Greg explained that longer sleepers may also have had other pre-existing conditions that might have contributed to their cognitive decline which weren\u2019t taken into account.<\/p>\n<p>\u201cFor example, this could include poor health, socioeconomic status or physical activity levels.<\/p>\n<p>\u201cAll of these factors together may explain why longer sleep was linked to cognitive decline,\u201d he added.<\/p>\n<h2>It\u2019s in your genes<\/h2>\n<p>A separate study, published in San Francisco, US, found that the amount we sleep is actually down to genetics.<\/p>\n<aside class=\"single__inline-module alignleft\">\n\t<\/aside>\n<p>Lead author of the study, neurologist Louis Ptacek said: \u201cThere\u2019s a dogma in the field that everyone needs eight hours of sleep, but our work to date confirms that the amount of sleep people need differs based on genetics.<\/p>\n<p>\u201cThink of it as analogous to height; there\u2019s no perfect amount of height, each person is different. We\u2019ve shown that the case is similar for sleep.\u201d<\/p>\n<p>The team have been studying sleep patterns for over ten years.<\/p>\n<p>They studied people with Familial Natural Short Sleep (FNSS), the ability to function fully on\u2014and have a preference for four to six hours of sleep a night.<\/p>\n<p>They did however state that studying the genes linked to sleep would be like a \u2018thousand piece jigsaw puzzle.\u2019<\/p>\n<p>The experts explained: \u201cSleep problems are common in all diseases of the brain.<\/p>\n<p>\u201cThis makes sense because sleep is a complex activity. Many parts of your brain have to work together for you to fall asleep and to wake up.<\/p>\n<p>\u201cWhen these parts of the brain are damaged, it makes it harder to sleep or get quality sleep.\u201d\u00a0<\/p>\n<p><em>This story originally appeared on <a href=\"https:\/\/www.the-sun.com\/health\/4905750\/exact-amount-sleep-adults-too-much-bad-brain\/\" target=\"_blank\" rel=\"noreferrer noopener\">The Sun<\/a> and has been reproduced here with permission.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Sleep is important for many reasons \u2013 but experts have warned that too much can actually be bad for your brain.
