What sleep problems can become more common as we age?

As we age, we can experience a variety of problems that either mess with our sleep or are sleep-related themselves, like depression (where you sleep too much) and anxiety (which can keep you awake). Circadian rhythm problems are frequent in shift workers, and up to 30 percent of people over 50 have restless legs syndrome—the periodic movement of limbs during deep sleep. This inability to stay asleep serves as the source of many sleep difficulties, but many can be treated with shifts in your sleep "hygiene," as well as with other tactics.
