Hey, sleepyheads. What you believe about sleep may be nothing but a pipe dream.Many of us have notions about sleep that have little basis in fact and may even be harmful to our health, according to researchers at NYU Langone Health's School of Medicine, who conducted a study published Tuesday in the journal Sleep Health."There's such a link between good sleep and our waking success," said lead study investigator Rebecca Robbins, a postdoctoral research fellow in the Department of Population Health at NYU Langone Health. "And yet we often find ourselves debunking myths, whether it's to news outlets, friends, family or a patient."Robbins and her colleagues combed through 8,000 websites to discover what we thought we knew about healthy sleep habits and then presented those beliefs to a hand-picked team of sleep medicine experts. They determined which were myths and then ranked them by degree of falsehood and importance to health.Here are 10 very wrong, unhealthy assumptions we often make about sleep, an act in which we spend an estimated third of our lives -- or, if we lived to 100, about 12,227 combined days.Stop yawning. It's time to put these unsound sleep myths to bed.1. Adults need five or fewer hours of sleep"If you wanted to have the ability to function at your best during the day, not to be sick, to be mentally strong, to be able to have the lifestyle that you would enjoy, how many hours do you have to sleep?" asked senior study investigator Girardin Jean-Louis, a professor in the Department of Population Health."It turns out a lot of people felt less than five hours of sleep a night was just fine," he said. "That's the most problematic assumption we found."We're supposed to get between seven and 10 hours of sleep each night, depending on our age, but the US 1806

FORT IRWIN, Calif. – The U.S. Army conducts tough realistic training at the Fort Irwin National Training Center in the deserts of California. There, you’ll find soldiers spending a 21-day rotation before they deploy overseas. “Our training area is bigger than the state of Rhode Island and its nickname is ‘The Box,’” said Sgt. Billy Dolan. “When they’re in ‘The Box,’ they’ll conduct 10 days of force on force training, followed by 10 days of live fire training,” said Lt. Kevin Lenahan. “This compound is supposed to give the rotational unit an urban fight.” According to the U.S. Army, the NTC training area contains an uncluttered electromagnetic spectrum and sprawls over 1,000 miles to facilitate large-scale maneuvering for Abrams tanks and other heavy wheeled and light mechanized vehicles. And, it possesses restricted airspace for aviation assets. This recipe cooks up the ideal site for the largest Army training exercises across the U.S. For some, they are conducting their final exercise prior to deployment. “A lot of my friends are getting deployed,” Dolan said. “Most of them are going to Syria or Afghanistan.” During one rotation, there are between 4,000 and 7,000 soldiers enduring intense training. “It gives the people who come here the first real world experience of what could happen without taking casualties,” Lenahan said. According to the U.S. Army, units are deployed to Fort Irwin for 21 days, 14 of which are spent in what is referred to as "The Box" (as in sandbox). It's the vast desert training area that includes 15 simulated towns and the previously mentioned tunnel and caves, as well as expansive gunnery ranges and tank battle arenas. The soldiers learn to navigate through civilians, insurgents, criminal networks and military forces, using what is known as Multiple Integrated Laser Engagement System (MILES). It’s basically a form a laser tag and allows the units to train using blanks. NTC rotations incorporate a complex scenario design laden with social, ethical and moral dilemmas; the goal of which is to develop leaders while exposing them to multifaceted problems. Units training at the NTC face a complex hybrid threat. Units must face a near-peer opposing force, while taking on an insurgent force. At the same time, they must assist the local towns and villages in any way possible. 2347

Former President Jimmy Carter suggested Friday that a full investigation into Russian interference in the 2016 election would show that Donald Trump didn't win the presidency."There's no doubt that the Russians did interfere in the election. And I think the interference, although not yet quantified, if fully investigated would show that Trump didn't actually win the election in 2016. He lost the election and he was put into office because the Russians interfered on his behalf," Carter said at the Carter Center's retreat in Leesburg, Virginia.Asked if he believes Trump is an illegitimate president, Carter paused for a moment."Based on what I just said, which I can't retract," Carter said to audience laughter. 729
