Your beauty rest might be protecting your brain health as well, a new study says.
Seniors with chronic insomnia might experience a faster decline in their memory and thinking skills as they age, researchers reported Thursday in the journal Neurology.
Chronic insomniacs had a 40% higher risk of developing dementia or suffering a decline in their cognitive skills, compared to those who get better sleep, the study showed.
That's the equivalent of an additional 3.5 years of brain aging, researchers said.
