While celebrities often seem immune to many of the health problems that plague us here in normal-town -- do they ever not look fabulous in a bikini? And when has someone ever walked the red carpet with a cold? -- there are several famous faces who have opened up about an important health issue that can lead to a host of serious complications: They can't sleep!
According to the National Sleep Foundation, 60 percent of Americans between the ages of 13 and 64 experience a sleep problem every night or almost every night, and 43 percent say they rarely or never get a good night's sleep on weeknights.
We know these stars -- and you! -- are juggling busy schedules and hectic home lives, but chronically skimping on sleep can lead to obesity, diabetes, heart problems, pain and other health concerns. Luckily, it's easy to start sleeping better tonight. Some general rules of thumb for catching more quality shut-eye: Power down your electronic devices (yes, all of them!) an hour or so before bedtime. The glaring light from the screens can seriously impact your sleep. Make sure your room is dark and cool and quiet, and try not to exercise or have caffeine too close to bedtime.
