...Even for those who still have their jobs, online dating has another advantage over more traditional dating rituals: it's cheaper. Julian Glasser, 32, a real estate broker in Chicago, was forced to make financial sacrifices after the declining housing market took a toll on his formerly ample commissions. Among them was a shift in his dating habits. "I was spending less time at bars and clubs meeting girls and more time at home trying to find girls on the Internet," he says. "I used to spend hundreds of dollars a week on my various dating efforts, whereas...
...likes to walk into work after just a few fitful hours of sleep. But now there's evidence that not getting enough sleep may have more serious consequences than dark circles under your eyes the next morning. Researchers at the University of Chicago report in the Journal of the American Medical Association that too little sleep can promote calcium buildup in the heart arteries, leading to the plaques that can then break apart and cause heart attacks and strokes...
...University of Chicago team documented for the first time exactly how much of a risk shortened shut-eye can be - one hour less on average each night can increase coronary calcium by 16%. Among a group of 495 men and women aged 35 to 47, 27% of those getting less than five hours of sleep each night showed plaque in their heart vessels, while 11% of those sleeping the recommended five to seven hours did, and only 6% of subjects sleeping more than seven hours each night showed such atherosclerosis. "We were surprised by the findings," says Diane Lauderdale...
...relied on people's self-reported accounts of their sleeping habits. The scientists knew that teasing apart the myriad processes that contribute to sleep, and then drawing scientifically sound connections between them and the host of things that can trigger heart disease, would be difficult at best. So the Chicago team isolated the most common confounding variables that could explain both poor sleep and heart problems, such as smoking, alcohol, and other medical conditions, and also found a way to record, as accurately as possible, the amount of sleep that the subjects got each night. Each volunteer wore a wrist...
...heart arteries isn't yet clear, but one explanation may involve inflammation. Too little sleep can raise cortisol levels, which fuels inflammation that can destabilize plaques. Once these deposits rupture, they can block vessels in the heart or brain, causing a heart attack or stroke. While the Chicago team did not track levels of cortisol to test this theory, future studies might...
