“How Losing Just 1% of Deep Sleep Each Year Increases Dementia Risk, Study Finds”

As we age, maintaining cognitive health becomes increasingly important, and recent research suggests that one often-overlooked factor could play a crucial role in reducing the risk of dementia: sleep. A 2023 study published on *Science Alert* highlights a striking connection between slow-wave sleep—often referred to as deep sleep—and dementia risk, especially for those over 60. The study found that for every 1 percent decline in slow-wave sleep per year, the likelihood of developing dementia rises by 27 percent. This finding underscores the importance of not only getting enough sleep but ensuring that it’s the restorative, deep sleep essential for brain health. As we explore the link between sleep and cognitive decline, it’s clear that prioritizing quality rest as we age may be more vital than we ever realized.
