Could getting more sunshine help slow some signs of aging?

Laurie Tarkan writes in the New York Times that “with age, people should make an effort to expose themselves to bright sunlight or bright indoor lighting when they cannot get outdoors.”  This will help regulate the body’s circadian rhythm, something researchers are just beginning to consider as a cause in a variety of signs of physical aging.  “As the eyes age, less and less sunlight gets through the narrowing pupil and yellowing lens.

“Older adults are at particular risk, because they spend more time indoors.”
