Dementia Risk

Study finds optimal sleep duration may reduce dementia risk

Getting 7 to 8 hours of sleep each night is linked to lower dementia risk, while too much daytime napping and sleepiness may raise your chances of developing the disease. Sleep patterns now could predict your brain health a decade or more down the road. Sitting for more than eight hours daily also increases dementia risk, so both sleep quality and daily movement matter for protecting your brain.
