Get a good night’s sleep
With too little sleep a risk factor for dementia, tending to this aspect of your health is important too.
While you tend to sleep less as you get older, paying attention to sleep hygiene—keeping your bedroom cool and dark, not using electronics in the hour before bed, and avoiding caffeine late in the day—can help you rest for longer.
And issues that can cause a chronic lack of sleep and heighten your risk of Alzheimer’s, such as sleep apnea, a bed partner with snoring problems, or prostate problems in men, are treatable.
On the flip side, recent research has found that too much sleep is also linked to a higher risk of cognitive decline and early death. A team of researchers in Japan reported that in a 10-year study of adults 60 and over, those who slept 10 hours or more a day were more than twice as likely to develop dementia or die, vs. those who slept five to 6.9 hours.
