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

GENEVA, Switzerland – The World Health Organization has declared the ongoing coronavirus outbreak a pandemic. "WHO has been assessing this outbreak around the clock and we are deeply concerned both by the alarming levels of spread and severity, and by the alarming levels of inaction," said Dr. Tedros Adhanom Ghebreyesus, Director-General of WHO. “We have therefore made the assessment that #COVID19 can be characterized as a pandemic”By definition, a pandemic is an outbreak of a disease that occurs over a wide geographic area and affects an exceptionally high proportion of the population.Ghebreyesus says the number of COVID-19 cases outside of China has increased 13-fold and the number of affected countries has tripled. “There are now more than 118,000 cases in 114 countries and 4,291 people have lost their lives,” said Ghebreyesus. In the days and weeks ahead, experts expect to see the number of cases, the number of deaths and the number of affected countries to climb even higher. "Pandemic is not a word to use lightly or carelessly,” said Ghebreyesu. “It is a word that, if misused, can cause unreasonable fear, or unjustified acceptance that the fight is over, leading to unnecessary suffering and death"Ghebreyesu says describing the outbreak as a pandemic doesn’t change WHO’s assessment of the threat the virus poses or what the organization is doing to combat it.According to Ghebreyesu, some of the hardest hit countries are seeing some progress in the fight against the virus."Of the 118,000 COVID-19 cases reported globally in 114 countries, more than 90 percent of cases are in just four countries, and two of those China and South Korea, have significantly declining epidemics," said Ghebreyesu.

GILBERT, Ariz. — In a bizarre two-day span, residents of an Arizona home say their concern is not just about what someone took from the house, but what they left behind. Police are now trying to identify a person caught on the home security camera Friday morning, who officers say may have been involved in a burglary at the Gilbert, Arizona, home the day prior. "The creepiness of it all is the fact of what he did, is kinda weird, it's mentally disturbing," said Max Ganley, who lives at the home. On Thursday morning, Ganley and his roommates awoke to the ring of their doorbell around 5 a.m. While no one was at the door, Ganley says someone snuck into their house through an unlocked back door and left a note. He provided KNXV with a picture of the note, which reads in part, "Please lock your doors. I only stole a knife and a flask. Stay safe. Could've killed you. Love you." 895
