This study suggests getting bright light early in the morning may support daytime energy in older adults.
Older eyes let in less light, and city apartments are often dim, which can throw off sleep and body clocks. In adults aged 63 to 92 across three European cities, people who got more natural daylight were more active, slept better and had fewer metabolic problems. Those given a bright indoor lamp used it on their own terms, and starting it before 10 a.m. was linked to more daytime activity and steadier rest-activity rhythms. The comparison group got no intervention, so this is early real-world evidence rather than a clean test.
