Do you worry that your workaholic ways are killing you? A new study says you may be right.
In an analysis of more than half a million men and women, those who put in long hours at the office were 33 percent more likely to suffer a stroke than their colleagues who clocked out earlier. Even those who worked just over 40 hours per week saw a significant increase in stroke risk, according to results published online in the journal Lancet.
A team of international researchers gathered data on hundreds of thousands of workers in the U.S., Australia, Israel and eight countries in Europe.
The researchers identified 528,908 people who were stroke-free when they joined a study. Over the next seven or so years, 1,722 of them suffered a stroke. But the odds weren’t spread equally — the more they worked, the greater the risk. Compared to people who worked 35 to 40 hours per week, those who logged 41 to 48 hours per week were 10 percent more likely to suffer a stroke, the researchers found. Workers who put in 49 to 54 hours per week were in greater peril — their stroke risk was 27 percent higher than for the baseline group. Worst off were those who worked at least 55 hours per week and saw their stroke risk jump by 33 percent.
The stroke risk was seen in both men and women, and in workers in all four regions studied, the researchers wrote.
Depth-sensing camera advance
Depth-sensing cameras can detect how far away a person or object is. Though these cameras have broad applications — in self-driving cars and navigation tools for the blind, for instance — they do not work well in bright sunlight.
A new imaging technology addresses this shortcoming, said researchers at Carnegie Mellon University and the University of Toronto.
Depth-sensing cameras, like Microsoft’s Kinect, rely on an infrared camera that generates a speckled pattern on an object. With simple geometry, the camera uses the pattern to calculate the distance of the subject. But the pattern is not visible to the camera in bright light. The new technology focuses on gathering only the bits of light that the camera actually needs.
