The recommended amount of sleep for adults is six to eight hours a night. Sleeping more than those hours is associated with an increased risk of death and cardiovascular diseases, says a global study published Wednesday in the European Heart Journal.Looking at data from 21 countries, across seven regions, the research team found that people sleeping more than the recommended upper limit of eight hours increased their risk of risk of major cardiovascular events, like stroke or heart failure, as well as death by up to 41%.But a possible reason for this could be that people have underlying conditions causing them to sleep longer, which in turn could raise the risk of cardiovascular disease or mortality, explain the authors of the study.The team, led by Chuangshi Wang, a Ph.D. student at McMaster and Peking Union Medical College in China, also identified a rising risk among daytime nappers."Daytime napping was associated with increased risks of major cardiovascular events and deaths in those with [more than] six hours of nighttime sleep but not in those sleeping [less than] 6 hours a night," Wang said.In those who underslept, "a daytime nap seemed to compensate for the lack of sleep at night and to mitigate the risks," Wang explained.Previous studies into this topic were mainly carried out in North America, Europe and Japan. The new study brings a global picture.But the findings are observational, meaning the cause of this association remains unknown."Even though the findings were very interesting they don't prove cause and effect," said Julie Ward, a senior cardiac nurse at the British Heart Foundation, who was not involved in the study.Having less sleep -- under six hours -- was also shown to increase these risks by 9%, compared with people who slept for the recommended six to eight hours, but this finding was not considered to be statistically significant by the team.In 2014, 35.2% of American adults reported not getting enough sleep with less than seven hours per night, according to the CDC. 2049

The three main wildfires raging in California have expanded rapidly, devouring virtually everything in their paths.One fire burned an area equivalent to the size of a football field every second during a period Thursday into Friday.Intense winds and low humidity are feeding the flames.

The U.S. has surpassed another bleak marker in the COVID-19 pandemic, as the country has reached 10 million confirmed cases of the virus, according to a database kept by Johns Hopkins.The milestone comes just hours after global cases surpassed 50 million, meaning about one out of every five people around the world diagnosed with the virus since the pandemic began has been diagnosed in the U.S.At least 237,000 Americans have died of the virus since the pandemic began. The U.S. continues to lead the world in both total cases and in deaths linked to the virus.The U.S. surpassed its 10 millionth case as the country deals with a disturbing spike in infections ahead of the winter months. The country surpassed 120,000 new cases in a single day three times last week, obliterating previous records. Prior to last week, the most confirmed cases the U.S. had seen in a single day was 102,000.The U.S. has recorded a million new cases of COVID-19 in the last 10 days alone. The country surpassed the 9 million case plateau on Oct. 30.In addition to the spike in cases, hospital resource use is also on the rise, and deaths linked to the virus are up slightly in recent days, though the death rate is not near what it was in March and April. Johns HopkinsHealth experts have warned that the U.S. is currently in a perilous position in the pandemic, with transmission rates as high as they have ever been as Americans move social gatherings indoors for winter months.In a memo last week, Dr. Deborah Birx — a member of the White House coronavirus task force — warned that the country is entering "the most deadly and concerning" phase of the pandemic.Late last month, Dr. Anthony Fauci — a member of the White House coronavirus task force and the county's top expert on infectious diseases — warned that the U.S. was in for a "whole lot of pain" if things didn't change soon.The U.S. did get some good news in the pandemic on Monday, as Pfizer announced that its vaccine candidate has been 90% effective in promoting immunity against the virus. However, even if the vaccine were to get FDA approval in the next few days, it would still take several months for most of the country to be vaccinated — and officials fear that vaccine skepticism could keep immunity levels below the threshold to stifle the virus. 2314

The United States Coast Guard embodies the saying, "always ready."When forecasting natural disasters, however, those two words become much more than a motto -- they could mean the difference between life and death.“With natural disasters, they’re unpredictable," said USCG Capt. Will Watson, commander, Sector New Orleans. "There’s uncertainty but what you have to do is lean back on your training.” With U.S. Coast Guard stations across the country on standby, Watson said his teams are ready to help whenever and wherever they are needed.“When the time comes, and you face something that you maybe weren’t otherwise prepared for, that’s when you exercise on-scene initiative,” he said. “You think critically. You think creatively. Remain adaptable and flexible and act.”Southeast Louisiana locals are calling the U.S. Coast Guard, “heroes,” saying they saved more than lives during past natural disasters.“One day, I got stuck in a boat and they come over here, five of them come here, and helped me out,” said local fisherman Tony Buffone, who lost his house during Hurricane Katrina -- one of the most deadly and expensive natural disasters to hit U.S. soil.During recent storms, Buffone is now using lessons he learned from the U.S. Coast Guard.“It’s good to have good Coast Guard,” he said. “We got a good Coast Guard crew right there.”As the Gulf Coast deals with another massive hurricane, the U.S. Coast Guard is doing what it does best: staying “always ready”.“We have resources, assets, people from all across the Coast Guard ready to support this fight,” Watson said. “And we’re ready; ready to respond to Hurricane Laura.” 1643
