Prolonged natural sunlight exposure was associated with the volumes of total brain (β: -0.051, P \u003c 0.001), white matter (β: -0.031, P = 0.023), gray matter (β: -0.067, P \u003c 0.001), and white matter hyperintensities (β: 0.059, P \u003c 0.001). These associations were more pronounced in males and individuals under the age of 60. With daily sunlight exposure approximately exceeding 2 hours, we observed that total brain volume and gray matter volume decreased, while white matter high hyperintensity volume increased with prolonged sunlight exposure duration.", "sig": "1c53248830b311811dabc85c95396b1edc3a4d301b2515748728be6de4f79174197fe32eb8359bb13c8def946ef6986fcf0ec2527dae481183b8e86aa79b870a" }
