Two particular phases in your nightly routine seem to play outsize roles in cognitive health.<\/p>\n

A good night\u2019s sleep isn\u2019t just about the number of hours you log. Getting quality sleep \u2014 the kind that leaves you feeling refreshed and ready for the day \u2014 is critical for a healthy brain.<\/p>\n

People with disturbed sleep, like insomnia or sleep apnea, have a higher risk<\/a> of developing dementia<\/a> than those with no sleep issues. Poor sleep can harm your brain in other ways, too. One study<\/a> found that people in their 30s and 40s with heavily disrupted sleep (such as frequent awakenings or movements) were two to three times more likely to test lower in executive function, working memory and processing speeds a decade or so later.<\/p>\n

Scientists think that deep sleep and rapid eye movement (or REM) sleep are particularly influential when it comes to brain health and dementia risk. A study published last month<\/a> on people with deep sleep and REM deficiencies found that the subjects\u2019 brains showed signs of atrophy in M.R.I. scans 13 to 17 years after the deficiencies were observed; the atrophy looked similar to what you\u2019d find in the early stages of Alzheimer\u2019s disease.<\/p>\n
