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.

The brain disorder, which occurs in about one in every 3,000 people, causes "extreme daytime sleepiness and sudden, irresistible bouts of sleep that can strike at any time," according to the National Institutes of Health.

Surfing the web, checking email or tweeting too close to bedtime, however, can send signals to your brain that disrupt the natural bedtime process and make it harder to drift off.

While many claim falling asleep to the TV helps them nod off, it can actually disrupt the sleep cycle. Your brain will still listen in on subtle changes in volume, even if you're asleep, Phillip Gehrman, Ph.D., CBSM, clinical director of the Behavioral Sleep Medicine Program at the University of Pennsylvania told The Huffington Post.
That could account for Clooney's trouble staying asleep. "Without question, I wake every night five times," he said.

Whether or not she really meant she'd been awake for a solid 72 hours or simply didn't sleep well three nights in a row, sleep deprivation has real consequences. Among the most frightening is a decrease in reaction time, which, if you're driving, could prove deadly.

Sleep apnea, which occurs when someone temporarily stops breathing during sleep, is more common in people who are overweight and/or have thick necks. At 7'1" and 325 pounds, Shaq certainly fits the bill.
Sleep apnea is often treated with a ventilation therapy known as CPAP (continuous positive airway pressure) that requires the snorer to sleep with a Darth Vader-esque mask. Shaq said he planned to wear his every night -- and joked he might wear it out on the town, too.

Reportedly among the ranks of mismatched sleep partners are musician and actor Kevin Jonas and his wife Danielle, according to In Touch Weekly. A friend of the couple said "Kevin and Danielle had never spent a night together until their wedding night, so she had no clue that he snores so loudly. She loves her husband, but now she sleeps in a guest room when he gets too noisy."
Snorers can try sleeping on their sides instead of their backs, using a pillow or a tennis ball sewn into a T-shirt to stop them from rolling over.


That may be true, but Bullock's extreme sleep deprivation could actually hurt little Louis. Severely skimping on sleep has been linked with a greater risk of making serious mistakes in doctors, police officers, truckers and others in positions that require long hours. To ensure you're giving little ones the best care, you need to take care of yourself first.
