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 Trump Administration wants to change the definition of a showerhead to let more water flow, addressing a pet peeve of the president who complains he isn’t getting wet enough.Publicly talking about the need to keep his hair “perfect,” President Donald Trump has made increasing water flow and dialing back long held appliance conservation standards — from light bulbs to toilets to dishwashers — a personal issue.But consumer and conservation groups said the Department of Energy’s proposed loosening of a 28-year-old energy law that includes appliance standards is silly, unnecessary and wasteful, especially as the West bakes through a historic two-decade-long megadrought.Since 1992, federal law has dictated that new showerheads shouldn’t pour more than 2.5 gallons of water per minute (9.5 liters). As newer shower fixtures came out with multiple nozzles, the Obama administration defined the showerhead restrictions to apply to what comes out in total. So if there are four nozzles, no more than 2.5 gallons total should come out between all four.The new proposal Wednesday would allow each nozzle to spray as much as 2.5 gallons, not just the overall showerhead.With four or five or more nozzles, “you could have 10, 15 gallons per minute powering out of the showerhead, literally probably washing you out of the bathroom,” said Andrew deLaski, executive director of the energy conservation group Appliance Standards Awareness Project.On the White House South Lawn in July, Trump made the issue personal:“So showerheads — you take a shower, the water doesn’t come out. You want to wash your hands, the water doesn’t come out. So what do you do? You just stand there longer or you take a shower longer? Because my hair — I don’t know about you, but it has to be perfect. Perfect.”DeLaski and officials at Consumer Reports said there’s been no public outcry or need for change. The Department of Energy’s own database of 12,499 showerheads showed 74% of them use two gallons or less water per minute, which is 20% less than the federal standard.“Frankly it’s silly,” deLaski said. “The country faces serious problems. We’ve got a pandemic, serious long-term drought throughout much of the West. We’ve got global climate change. Showerheads aren’t one of our problems.”Energy Department spokeswoman Shaylyn Hynes said the 2013 Obama definition of showerhead clashes with what Congress intended and the standards of the American Society of Mechanical Engineers.If the rule is adopted, Hynes said it would be “allowing Americans — not Washington bureaucrats — to choose what kind of showerheads they have in their homes.”Officials at the industry group Plumbing Manufacturers International did not respond to a request for comment.Appliance and plumbing energy and water conservation standards save consumers about 0 a year on energy bills, deLaski said.If people are having trouble getting water flowing in their shower, they should check their home’s water pressure and can replace a faulty showerhead for not much money, deLaski said.A 2016 test of showerheads by Consumer Reports found that the best rated showerheads — including a model — provided a pleasing amount of water flow and met federal standards, according to David Friedman, a Consumer Reports vice president and former acting assistant energy secretary.DeLaski said he has had a hard time understanding the president’s shower concerns.“If the president needs help finding a good shower, we can point him to some great consumer websites that help you identify a good showerhead that provides a dense soak and a good shower,” deLaski said. 3624

The US Consumer Product Safety Commission (USPSC) announced Wednesday that it is issuing a recall of Xtava Allure hair dryers due to concerns that they could catch fire or deliver electrical shocks.According to the USPSC, the recall affects more than 200,000 hair dryers.Nearly 200 people have reported the dryers and power cords have either "overheated, melted, exploded or caught fire" while in use. Eighteen people sustained burns while using the product, with one of those being classified as a "severe" burn.The dryers were sold online at Amazon, eBay, Walmart and Groupon, in addition to Xtava's own website. They were sold individually or in a hair care pack that included "treatment products, a flat iron or a diffuser."The affected products include the following SKU numbers on a label on the back:  XTV010001, XTV010001N, XTV010002, or XTV010002N.Those with the dryers should contact Xtava directly.

The University of Washington’s Institute for Health Metrics and Evaluation now projects that 33,000 American lives would be saved between now and October 1 by near universal wearing of masks.The IHME released the updated model on Wednesday.The IHME’s coronavirus projections have been frequently cited in the past by the White House’s coronavirus task force. The group uses state data along with other metrics to create projections on the number of coronavirus-related deaths throughout the US.The projection state that the US is currently on track to have an additional 58,000 coronavirus-related deaths between now and October 1. But that number drops to just 23,000 if masks are universally worn in public. Those figures are on top of the over 121,000 reported coronavirus-related deaths since the beginning of the pandemic.The IHME’s model projects that the US death toll will stay consistent on a per-day basis between now and September, before starting to increase in the fall. But the model projects that fewer than 100 Americans will die per day from coronavirus by September if masks are worn.The IHME’s latest model projects that coronavirus-related deaths will continue to surge in the states of Texas, Arizona and Florida in the coming weeks, while leveling or dropping off in many other states.To see a state-by-state breakdown of the IHME’s projections, click here.Last month, a study in the Lancet found that the use of masks and respirators by those infected with the virus reduced the risk of spreading the infection by 85%. The authors analyzed data that showed that N95 respirators in healthcare settings were up to 96% effective. Other masks were found to be 77% effective. 1701
