A study involving about 88,000 people found that greater exposure to light during the day was associated with a lower risk of developing dementia in the following years. Exposure to bright light of 5,000 lux or more for 42 minutes a day was associated with a 17% reduction in relative risk. The reduction reached 41% among night owls and 27% among carriers of the APOE ε4 gene variant. The researchers say that increasing daytime light exposure may be a simple, low-cost strategy to support brain health, but the study was observational and does not establish a causal relationship.
