The Link Between Deep Sleep and Dementia Risk

Inadequate sleep, specifically a reduction in deep sleep, is associated with an increased risk of developing dementia, according to a study from Monash University. Researchers found that as little as a 1% decline in deep sleep each year for individuals over 60 years old equated to a 27% higher risk of dementia. Deep sleep is crucial for brain health, as it helps remove waste, consolidate memories, and protect against dementia risk factors. The study highlights the importance of prioritizing good sleep as part of a healthy lifestyle to potentially lower the risk of dementia.
