Good sleep often falls by the wayside when things get really busy. And surveys suggest few adults get the recommended seven to eight hours a night. But over time, a chronic lack of sleep can affect your memory.
Avoid what experts call "sleep bulimia": super-late nights followed by sleep-in weekends. Rather stick to a routine and get enough sleep most nights of the week. Also don't feel guilty for napping – research shows taking a nap may boost a sophisticated kind of memory that helps you see the big picture and get creative.
