People Are Sleeping in 20-Minute Bursts To Boost Productivity. But Is It Safe?
About a third of Americans don’t get enough sleep. But there’s a small group of people actively trying to spend less time in bed, not more: polyphasic sleepers. Part productivity hack, part science experiment, polyphasic sleep is rumored to have fueled great minds, including those of Leonardo da Vinci and Nikola Tesla. The odd sleeping habit has now caught on among Silicon Valley types eager to milk as many productive hours from the day as possible, and has spurred books, an active Reddit community and even a Polyphasic Sleep Society. Here’s what to know about the unorthodox sleep practice. What is polyp...

Light Pollution Is Getting Worse Every Year. That ’s Bad For Your Health
Nothing has captured the march of wealth and progress like any society’s ability to light up the night—first with campfires and torches, then with gas lamps, finally with incandescent lights. Franklin Roosevelt’s 1936 Rural Electrification Act was an effort both to bring modernity to the 90% of American farms that lacked electricity and to help jolt the American economy, which was still deep in the Depression. The modern nighttime image of the Korean peninsula as seen from space, with darkness north of the 38th parallel and brilliant light in the vibrant south, powerfully captures the connection between c...

Avoid eating just before your bedtime, study recommends
Conclusions Previous research suggests we may be better off consuming more of our calories earlier on in the day, when we have a full, active day ahead of us to use up the energy. It's also been observed that people who consume large calorific meals late in the evening can have a higher body weight. In a sense, the results of this study seem plausible and don't really say anything different from what's already been observed. But as this is a cross-sectional study, it can't really prove very much. The study involved a small, select sample of US university students. Their results can't be applied to everyone, as they have di...

The next time you tell yourself that you'll sleep when you're dead, realize that you're making a decision that can make that day come much sooner.
