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

TERRE HAUTE, Ind. — An upcoming rule change at the U.S. Department of Justice means federal inmate executions, which are currently carried out by lethal injection could happen by other means, such as a firing squad or electrocution.Currently, all federal executions are done via lethal injection unless a court specifically orders otherwise. The rule change gives the federal government greater flexibility to execute people by other means.The change states that federal executions are to be carried out by lethal injection “or by any other manner prescribed by the law of the State in which the sentence was imposed or which has been designated by a court.”According to the Death Penalty Information Center, all states that allow the death penalty authorize a lethal injection method. Nine states allow electrocution, seven allow lethal gas and three allow a firing squad. Most states that allow methods other than lethal injection do so only under the provision that the injection is found to be unconstitutional, unavailable or impractical.The DOJ rule change goes into effect on Dec. 24, before three more federal inmates are scheduled to be executed. Inmates are scheduled to be executed on Jan. 12, Jan. 14 and Jan. 15.If executions by other means will happen, it’s unlikely they will happen at the Federal Bureau of Prisons in Terre Haute, where federal executions typically take place. The DOJ notice states that the Terre Haute complex is equipped for carrying out executions only by lethal injection. If another method is used, it may happen somewhere else.The federal government has executed 10 people in 2020.Click here to read more about the rule change.This story was originally published by Matt McKinney on WRTV in Indianapolis. 1752

TAMPA, Fla. -- A Tampa man is speaking to national supermarket chains after inventing a device to sanitize shopping carts.Adam Labadie created a product known as "The Arch Cart Sanitizer." The device sanitizes shopping carts in a few seconds. It uses an organic, EPA, FDA approved solution to kill COVID-19. "We ship a dry package to the store. We don't ship liquid across the country," he said.Studies show shopping cart handles have bacteria on them. It is one of the most commonly touched items in a store."Customers now are expecting a clean cart. They expect a clean store and a clean cart," said Labadie. Labadie said he first noticed a trash can full of used wipes at a local grocery store. He also saw a lot of trash while snorkeling and diving in Florida."I went and I looked at the trash can. It was a full trash can full of wipes," he said."I wanted to find another solution," he added.Labadie said his invention could help eliminate the use of wipes at grocery stores. He hopes to start production in the next few weeks."We'll be sending out free demos, free demos to grocers...some in the Northeast and some in the South in about 3 weeks so it's super exciting for me. It means I get to showcase my baby," said Labadie. The father of two was laid off at the start of the pandemic. He began working on his invention. He said he spends 15 hours working in the garage or on his computer."Failure is always part of life and you just try to challenge yourself, figure out the next thing," he said."November, December, hopefully, we'll start seeing it in some stores," Labadie added.This story was first reported by Julie Salomone at WFTS in Tampa, Florida. 1729

TAMPA, Fla. — New court documents show a 3-year-old girl killed in a crash last month was not properly restrained.According to police, the mother, who was driving the car, pulled in front of another vehicle around 7:50 a.m. on January 16, near the intersection of North 40th Street and East Osborne Avenue.According to court documents, three children in the vehicle were in the car on booster seats, however, the booster and car seats were not secured to the vehicle. It's the law in Florida for children to be in a car seat until they turn four years old. Children must be in a booster until they are six years old. Failure to comply can result in a moving violation and about a 0 fine. If a child is injured or killed in a crash and was not properly restrained, child neglect charges can be filed.Police are still investigating the circumstances surrounding the crash on Jan. 18. No charges have been filed yet. 944
