RealFeedApp Bright light exposure reduces dementia risk by 17 percent
A study of nearly 88,000 older adults found that daily exposure to bright light (5,000 lux or more) for at least 42 minutes was associated with a 17 percent lower relative risk of dementia. This association was stronger than six other traditional risk factors, including obesity, and reached up to 41 percent lower risk for 'night owls'.
