The secret to success isn't just good performance -- according to HuffPost President and Editor-in-Chief Arianna Huffington, you also have to let your head hit the pillow in order to get there.

As someone who ignored her relationship with sleep for a long time, Huffington said recently that it took a health scare to open her eyes to her poor sleep habits. After passing out from exhaustion one night, she decided it was time to take action.

"That's when I knew I needed to renew my estranged relationship with sleep," Huffington said. "We had once been quite close. It had been very important early in my career. But, as time went by, responsibilities piled up and we had grown apart. I had basically begun to think I could survive on very little sleep. But there are few wakeup calls as effective as waking up on the floor in a pool of blood."

Huffington says that creating a healthy relationship with sleep is crucial not only to your health, but to your success in work and in life. In a world where we're always plugged in, it's important to step back and reconnect with our minds and our health in order to boost performance.

"The prevailing culture tells us that nothing succeeds like excess, and that working 70 hours a week is better than working 60," Huffington said. "We're told that being plugged in twenty-four-seven is expected, and that sleeping less and multi-tasking more are an express elevator to the top."

So how do we get to the top? By closing our eyes.

"The world is in desperate need of big ideas -- and there are many, many of them locked inside of us," Huffington said. "We just need to close our eyes to see them. So, ladies and gentlemen, shut down your engines and get some sleep."

  • ...Increase Stroke Risk

    Even without the typical risk factors, like being overweight or having a family history, short sleep can up your risk for stroke, according to 2012 research. Adults who regularly slept fewer than six hours a night had <a href="">four times the risk of stroke symptoms</a>, HuffPost reported.

  • ...Lead To Obesity

    Too little sleep can spur some less-than-ideal food choices, including <a href="">serving yourself larger portions</a>, and a hankering for junk food, thanks to some complicated hormonal changes that occur when you don't get sufficient shuteye. It seems that six hours of sleep or less <a href="">bumps up production of the hunger hormone ghrelin</a> and limits leptin, which helps you balance your food intake, according to a 2012 review of 18 studies of sleep and appetite.

  • ...Up Diabetes Risk

    A pair of small studies from 2012 examined the link between poor sleep and insulin resistance, a telltale risk factor for diabetes. One found that among healthy teenagers, the <a href="">shortest sleepers had the highest insulin resistance</a>, meaning the body is <a href="">not using insulin effectively</a>, according to the National Institute of Diabetes and Digestive and Kidney Diseases. The second study examined fat cells, in particular, and found that cutting back on sleep <a href="">increased insulin resistance in these cells</a>, even when <a href="">diet and calorie intake were restricted</a>, reported.

  • ...Fuel Memory Loss

    You probably know that on the days when you are most tired, you're forgetful and unfocused -- but sleep deprivation can lead to <a href=""><em>permanent</em> cognitive issues</a>. The less we sleep, the less we benefit from the memory-storing properties of sleep. But additionally, a lack of sleep can cause <a href="">"brain deterioration,"</a> according to a 2013 study, which may at least in part explain memory loss in seniors.

  • ...Damage Bones

    At least in rats, long-term <a href="">sleep deprivation seems to contribute to osteoporosis</a>, according to a 2012 study. Researchers found <a href="">changes to bone mineral density and bone marrow</a> in the rodents when they were deprived of shuteye over a period of 72 days. "If true in humans, and I expect that it may be, this work will have great impact on our understanding of <a href="">the impact of sleep deprivation on osteoporosis</a> and inability to repair bone damage as we age," Steven R. Goodman, Ph.D., editor-in-chief of Experimental Biology and Medicine, said in a statement.

  • ...Increase Cancer Risk

    A small (but growing) body of research suggests that short and poor sleep can up risk for certain types of cancer. A 2010 study found that among 1,240 people screened for colorectal cancer, the 338 who were diagnosed were <a href="">more likely to average fewer than six hours of sleep</a> a night. Even after controlling for more traditional risk factors, polyps were more common in people who slept less, according to the study. Getting just six hours of sleep a night has also been linked to an <a href="">increase of recurrence in breast cancer patients</a>. The study's author has pointed to more and better sleep as a possible pathway of reducing risk and recurrence.

  • ...Hurt Your Heart

    The stress and strain of too little sleep can cause the body to produce more of the chemicals and hormones that can lead to heart disease, according to 2011 research. The study found that people who slept for six hours or less each night and have problems staying asleep had a 48 percent <a href="">higher risk of developing or dying from heart disease</a>.

  • ...Kill You

    It's not just heart problems that can lead to sleep-deprivation-related death. In fact, <a href="">short sleepers seem to die younger</a> of any cause than people who sleep about 6.5 to 7.5 hours a night, TIME reported. A 2010 study examined the impact of short sleep on mortality and found that <a href="">men who slept for less than six hours of sleep a night were four times more likely</a> to die over a 14-year period. The study's authors called this link "a risk that has been underestimated."
