Sticking to a normal daily rhythm -- being active during the day and sleeping at night -- can have more benefits than you might expect.A new study found that it is linked to improvements in mood and cognitive functioning as well as a decreased likelihood of developing major depression and bipolar disorder.The study, published Tuesday in the journal The Lancet Psychiatry, looked at disruptions in the circadian rhythms -- or daily sleep-wake cycles -- of over 91,000 adults in the United Kingdom. It measured these disruptions using a device called an accelerometer that is worn on the wrist and measures one's daily activity levels. The participants were taken from the UK Biobank, a large cohort of over half a million UK adults ages 37 to 73.The researchers found that individuals with more circadian rhythm disruptions -- defined as increased activity at night, decreased activity during the day or both -- were significantly more likely to have symptoms consistent with bipolar disorder or major depression. They were also more likely to have decreased feelings of well-being and to have reduced cognitive functioning, based on a computer-generated reaction time test.For all participants, activity levels were measured over a seven-day period in either 2013 or 2014, and mental health proxies such as mood and cognitive functioning were measured using an online mental health questionnaire that participants filled out in 2016 or 2017."It's widely known that a good night's sleep is a good thing for well-being and health. That's not a big surprise," said?Dr. Daniel Smith, professor of psychiatry at the University of Glasgow and a leading author on the study. "But I think what's less well-known and what comes out of this work is that not only is a good night's sleep important, but having a regular rhythm of being active in daylight and inactive in darkness over time is important for mental well-being."The findings were found to be consistent even when controlling for a number of influential factors including age, sex, lifestyle, education and body mass index, according to Smith."I think one of the striking things that we found was just the consistency in the direction of our association across everything we looked at in terms of mental health," Smith said.Daily circadian rhythm is controlled by a collection of neurons in an area of the brain called the hypothalamus. The hypothalamus helps regulate a number of important behavioral and physiological functions such as body temperature, eating and drinking habits, emotional well-being and sleep, according to the?National Institute of General Medical Sciences.The findings are consistent with research indicating a link between sleep disruptions and mood disorders. A 2009 study, for example, showed that men who worked night shifts for four years or more were more likely to have anxiety and depression than those who work during the day.However, the new study is the first to use objective measurements of daily activity and is among the largest of its kind, according to?Aiden Doherty, senior research fellow at the University of Oxford, who was not involved in the research."This study is the first large-scale investigation of the association of objectively measured circadian rhythmicity with various mental health, well-being, personality and cognitive outcomes, with an unprecedented sample size of more than 90 000 participants," Doherty wrote in an email."Previous studies have been very small (in just a few hundred people), or relied on self-report measures (asking people what they think they do). ... However, this study used objective device-based measures in over 90,000 participants; and then linked this information to standard measures of mood disorders, subjective well-being, and cognitive function," he added.The findings have significant public health consequences, particularly for those who live in urban areas, where circadian rhythms are often disrupted due to artificial light, according to Smith."By 2030, two-thirds of the world's population will be living in cities, and we know that living in an urban environment can be pretty toxic to your circadian system because of all the artificial light that you're exposed to," Smith said."So we need to think about ways to help people tune in to their natural rhythms of activity and sleeping more effectively. Hopefully, that will protect a lot of people from mood disorders."For those who struggle to maintain a consistent circadian rhythm, certain strategies -- such as avoiding technology at night -- have proven to be an important part of good sleep hygiene."Not using your phone late at night and having a regular pattern of sleeping is really important," Smith said. "But equally important is a pattern of exposing yourself to sunshine and daylight in the morning and doing activity in the morning or midday so you can actually sleep properly."Based on the observational nature of the study, the researchers were unable to show causality, meaning it is unclear whether the sleep disturbances caused the mental health problems or vice versa."It's a cross-sectional study, so we can't say anything about cause and effect or what came first, the mood disorder or the circadian disruption," said Kristen Knutson, associate professor of neurology at Northwestern's Feinberg School of Medicine, who was not involved in the study."And it's likely they affect each other in a circular fashion," she added.The researchers also looked exclusively at adults between age 37 and 73, meaning the results may not apply to younger individuals, whose circadian rhythms are known to be different than those of older adults, according to Smith."The circadian system changes throughout life. If you've got kids, you know that very young kids tend to be nocturnal," Smith said. "My suspicion is that we might observe even more pronounced effects in younger samples, but that hasn't been done yet, to my knowledge."But the study adds more credence to the idea that sleep hygiene -- including maintaining a consistent pattern of sleep and wake cycles -- may be an important component of good mental health, according to Smith."It's an exciting time for this kind of research because it's beginning to have some real-world applications," Smith said. "And from my point of view as a psychiatrist, I think it's probably under-recognized in psychiatry how important healthy circadian function is, but it's an area that we're trying to develop." 6496

TALLAHASSEE, Fla. — Much like the rest of the country, unemployment rates skyrocketed in Florida at the onset of the COVID-19 pandemic. And while the Florida unemployment rate has fallen somewhat to 7.6%, many in the state are still in need of help and may get it through a program called EB or Extended Benefits.In October alone, more than 10,000 people applied for unemployment in the Tampa Bar area — including 7,338 in Hillsborough County and 3,799 in Pinellas County."We continue to see unemployment problems within our office; it's mostly coupled with eviction notices," said State Representative Anna Eskamani, a Democrat whose district covers the Orlando area.Eskamani has fielded calls from Florida's unemployed since March."We need political back-and-forth to stop. The American people are in desperate need of relief," she said.The regular 12 weeks of benefits for those unemployed only lasted until about mid-June. That's when many applied for PEUC, a 13-week extension that took extended benefits to about mid-September.With the state's unemployment rate remaining above 5% for as long as it has, regular unemployment benefits were extended but haven't been made available yet."They're trying to integrate it into the connect system, which is why they're saying December it's going to be available," Eskamani said.In order for Floridians to get extended benefits — or EB — their PEUC benefits must have been used up between June 7 and Nov. 7."I actually think the gap that's being sent by the US Department of Labor catches most people," Eskamani said.It could, however, have an impact on Disney World employees, many of whom were furloughed or laid off amid an extended park closure. What happens for others seeking unemployment in 2021 is still unclear.Eskamani says that by then, the state legislature should officially be able to file a bill that she and other lawmakers drafted in October, hoping to get claimants more money for a longer period of time."(I want to) increase the benefit amount to 0 — change the sliding scale of what's available to us at the limit of 26 weeks, which is the national average," she said. "Put in place time restrictions for when the (Florida Department of Economic Opportunity) has to get back to you on your eligibility status."Eskamani also hopes to extend benefits to self-employed who are out of work and have the legislature's Oversight Committee hold the Florida Department of Economic Opportunity accountable.She says once the bill filed, she hopes to push the bill into committee hearings. Lawmakers go back for organizational meetings in a week and a half.This story was originally published by Heather Leigh on WFTS in Tampa, Florida. 2705

The Australian refugee deal that US President Donald Trump once derided as "stupid" and "horrible" is happening.The first group of refugees being held at Australian offshore detention centers on Nauru and Papua New Guinea's Manus Island will leave for the US in the "coming weeks," the Australian government has confirmed in a statement."There will be about 25 (refugees) from both Manus and Nauru, will be going to the United States and I just want to thank again President Trump for continuing with that arrangement," Australian Prime Minister Malcolm Turnbull?said in an interview with CNN's Australia affiliate Seven News.Under the terms of the arrangement, refugees selected by the Australian authorities for resettlement in the US are not guaranteed entry into the country. They must first pass a strict vetting process -- which can take months.An official at the US State Department told CNN on Wednesday that to date, they have determined one individual meets resettlement requirements and will be moved in "the coming weeks." The official said he expects the first batch of approved refugees to be notified within days."We expect refugees to travel to the United States in the coming weeks," the official said.Trump made it clear to Turnbull he was not a fan of the deal during their first phone call following Trump's inauguration in January, details of which were later revealed in a?leaked transcript?published by the Washington Post in August."I am the world's greatest person that does not want to let people into the country. And now I am agreeing to take 2,000 people and I agree I can vet them, but that puts me in a bad position. It makes me look so bad and I have only been here a week," Trump said."This is a big deal," Turnbull responded. "It is really, really important to us that we maintain it. It does not oblige you to take one person that you do not want.""This is a stupid deal. This deal will make me look terrible," Trump said, adding later "I think it is a horrible deal, a disgusting deal that I would have never made."The deal was negotiated by former US President Barack Obama and involved the transfer of 1,250 refugees from Australia in exchange for a group of Central American refugees from camps in Costa Rica.Towards the end of their phone call, Trump appeared to concede that he would stick with the deal, but he said he would tell the American people that "I hate it." 2432
