Why Deep Sleep Matters for Brain Health

Ever wondered why deep sleep feels so refreshing? It’s not just about waking up energized—your brain actually depends on it. A recent study found that for people over 60, losing just 1% of deep sleep each year could raise dementia risk by 27%. Deep sleep, also called slow-wave sleep, is when your body repairs itself and your brain clears out waste, including proteins linked to Alzheimer’s. Researchers tracked over 300 older adults for years and noticed that less deep sleep often came before signs of dementia. Even after considering factors like age, genetics, and medication, the link remained strong. While the study didn’t prove that poor sleep causes dementia, it suggests that protecting your deep sleep could help keep your mind sharp as you age. Prioritizing good sleep habits might be one of the simplest ways to support long-term brain health. #DeepSleep #BrainHealth #DementiaPrevention #Health #Wellness
