🧠 Poor Sleep Speeds Brain Aging - New research shows that chronic insomnia - trouble sleeping at least 3 nights/week - may increase your risk of cognitive decline.
In a 5-year study of older adults, those with insomnia were 40% more likely to develop mild cognitive impairment or dementia. Brain scans even revealed changes linked to Alzheimer’s.
The good news? Treating insomnia and improving sleep quality may help protect your brain as you age. Sleep isn't just about energy—it’s brain preservation. https://substack.com/home/post/p-177004675
