This could be the best time exercise for heart and lung health, scientists say
The best time to workout to boost your heart and lung health may be in the morning, researchers say.
The reason may be linked to our circadian rhythms, or the body's natural 24-hour clock. The circadian clock helps to regulate certain functions, including the release of hormones and our core temperatures. That indicates that the time of day you're most active could impact how well you perform, Dr. Karyn Esser, the chair of the University of Florida College of Medicine's Department of Physiology and Aging, said, according to Health.com.
In older adults, 'more rhythmic activity behavior and earlier time of peak activity were associated with better cardiorespiratory fitness and walking energetics,' a group of international scientists said late last month.
Walking energetics refers to how well the body utilizes energy when you're getting your steps in.
Esser was the senior author of the findings published in the journal Medicine & Science in Sports & Exercise.
It is important to note that every person has a chronotype, or a natural preference of the body for wakefulness and sleep at certain times of the day, according to The Sleep Foundation. Knowing your chronotype, and timing you activities accordingly, could significantly impact your health and fitness.
To reach these conclusions, they examined the health data of 799 adults from the Study of Muscle, Mobility and Aging. The patients, who wore wrist accelerometers over a week to measure their physical activity, had an average age of 76 years. The patients also underwent cardiopulmonary exercise testing.
The authors also found that working out at the same time each day was associated with better health outcomes.
Still, more research is needed to understand this relationship.
The Centers for Disease Control and Prevention recommends that adults get at least 150 minutes of moderate intensity physical activity a week, and two days of muscle-strengthening activity. That will help to reduce the risk of heart disease and stroke, as well as other negative health outcomes.
Previous studies have also indicated that morning exercise was associated with a lower risk of cardiovascular disease. But, working out at other times of day also provide benefits. The American Heart Association says what you do may be more important than when you do it.
'While we are living longer, in general, we are not living healthier,' Esser told MedicalNewsToday. 'So it is important to find ways to help people maintain or improve their health while aging, [to] improve quality of life and diminish the impact of age-related chronic diseases.'

Elon Musk issues 'catastrophic' warning about NASA's $150 billion ticking timebomb
Elon Musk is again calling for NASA to scuttle the International Space Station (ISS) after a former engineer of the agency revealed hidden problems with its structure. Casey Handmer, a physicist and engineer who worked at NASA's Jet Propulsion Laboratory (JPL) for four years, posted on X that the 26-year-old station's structure integrity is far worse than the public knows. 'We could wake up tomorrow and find, with zero warning, that it has failed catastrophically,' Handmer warned on X Thursday. Musk, the CEO of SpaceX, quickly responded, saying that even though his commercial space company makes billions from delivering cargo and astronauts to the station, it should be brought down by 2027. 'There are potentially serious concerns about the long-term safety of the [ISS]. Some parts of it are simply getting too old and obviously that risk grows over time,' Musk posted early Friday morning. The renewed push to decommission ISS came hours after NASA delayed a private astronaut mission by Axiom Space Inc because of a pressure leak in one of the station's Russian-built sections, meaning there could be less air to breathe. The billionaire leader of SpaceX, Tesla, and X has been calling for NASA to scrap the $150 billion project since February. At the time, Musk was also the head of the Department of Government Efficiency (DOGE) and recommended to President Trump that the station be brought down 'as soon as possible.' Casey Handmer, a physicist and engineer who worked at NASA for 4 years, warned that the International Space Station has more structural problems than are being reported publicly In his post, Handmer warned that these leaks are becoming more frequent and taking place in multiple sections of the ISS. He added that as the station's aluminum shell flexes, the metal fatigues and gets harder, which increases the risk of it cracking. The former NASA employees revealed that 'multiple cracks have been discovered,' even though none of these pressurized sections were meant to crack. First launched in November 1998, the ISS is nearing the end of its operational lifespan and has been showing signs of wear and tear for years. Last November, another leak in the Russian segment that had been worsening for five years sparked fears that the astronauts on board may need to evacuate, causing NASA to warn that this could lead to a 'catastrophic failure' of the space station. Astronauts have been patching the leak and keeping the module it's located in mostly sealed off to eliminate any immediate threat to their safety. The new issue this month emerged shortly before the launch of Axiom Mission 4, a private spaceflight to the ISS operated by Axiom Space, in partnership with SpaceX and NASA. The mission was set to deliver four astronauts to the ISS for a 14-day stay. The crew aimed to conduct approximately 60 scientific studies, focusing on microgravity research in technology, life sciences, and other fields. In a statement, NASA said that a new launch date has not been scheduled as the investigation into the pressure leak continues. The growing list of alarming maintenance issues are partly what drove NASA and its ISS partners - Russia, Japan, Canada, and 11 European countries - to make plans to retire the ISS by 2030. However, Musk declared on Friday that he 'would like to go on record recommending that it be de-orbited within 2 years.' Musk's SpaceX was tasked with building the spacecraft that would assist in the deorbiting of the station. In June 2024, NASA awarded SpaceX a $843 million contract to build the deorbit vehicle, or USDV, that will be used to safely guide the ISS back into the Pacific Ocean in 2030. That being said, decommissioning the ISS ahead of schedule is not that simple and would require agreement from all the space station's partners, not just the approval of President Trump. Trump could propose shutting down the space station before 2030, but in addition to getting the other ISS partners on board, funding for the deorbit mission has to come from Congress. Moreover, the SpaceX contract only covers the cost of building the USDV, not the entire deorbit mission. Last summer, former NASA Administrator Bill Nelson was seeking $1.5 billion from the US government to cover the entire project.

Barry Sanders reveals he suffered a heart attack last year
June 13 - Barry Sanders is imploring folks to undergo a complete medical checkup, nearly one year after the Hall of Fame running back suffered what he initially labeled as a heart-related health scare. During an exclusive interview with CBS Sports, Sanders disclosed that the "health scare" indeed was a heart attack. "Of all things, I don't know why, that just never entered my mind," Sanders said of his heart attack. "I'm learning through this process that there aren't necessarily any warning signs, unless you do what we're encouraging people to do, which is to go the doctor, get tested for LDLC levels, or bad cholesterol. That's the only way to find out if you have high cholesterol. It's not something you're going to be able to feel. You don't have to fit a certain physical profile." Sanders, 56, shared his experience in "The Making of a Heart Attack," which will air on Saturday at 1 p.m. ET on A&E. He said he woke up with a burning sensation in his chest while attending a recruiting visit for his son. "I couldn't believe it, honestly. I thought it was like heartburn, but it just kind of persisted," Sanders said. He said he drove himself to the emergency room later that afternoon, with tests revealing that his enzyme levels were "really high and getting higher." Sanders was a first-ballot selection to the Pro Football Hall of Fame in 2004. The Lions made Sanders, a Heisman Trophy winner at Oklahoma State, the third overall pick of the 1989 NFL Draft. He spent his entire 10-year career with Detroit (1989-98), running for 15,269 yards -- now the fourth-most rushing yards in NFL history -- and 99 touchdowns while catching 352 passes for 2,921 yards and 10 TDs. Sanders rushed for 2,053 yards in 1997 when he shared Most Valuable Player honors with Green Bay quarterback Brett Favre. Sanders was selected to 10 Pro Bowls in 10 seasons, named first-team All-Pro six times, voted the Offensive Rookie of the Year in 1989 and selected to the NFL 100 All-Time Team. --Field Level Media

Bernie Sanders and RFK Jr. find rare common ground over pharmaceutical ads on TV: ‘Sick and tired'
Wegovy, Farxiga, Vraylar ... the stream of drug ads on TV has gotten so pervasive that they're bringing together an unlikely pair of politicians to take them on. Independent Vermont Sen. Bernie Sanders, who caucuses with Democrats, is backing an effort pushed by Trump Health and Human Services Secretary Robert F. Kennedy Jr. to ban pharmaceutical ads on TV. Sanders introduced the End Prescription Drug Ads Now Act alongside fellow independent Senator Angus King of Maine. They both caucus with the Democrats. If passed, the legislation would ban prescription drug ads from TV, radio, print, digital platforms, and social media. Those critical of the ads argue that they push the price of healthcare even higher, even as they don't help to improve the care patients receive. Supporters of the ads say that they can increase patients' understanding of the care available. However, most wealthy nations, apart from the U.S. and New Zealand, ban pharmaceutical ads, Newsweek noted. Kennedy has yet to comment on the legislation, which Sanders and King revealed on Thursday. They noted that the pharmaceutical industry spent more than $5 billion on TV ads last year, adding that many of the drugs advertised cost more in the U.S. than they do in countries where pharmaceutical ads are banned. "The American people are sick and tired of greedy pharmaceutical companies spending billions of dollars on absurd TV commercials pushing their outrageously expensive prescription drugs," said Sanders, calling the U.S. policy of allowing such ads an "international embarrassment." Anna Bahr, Sanders' director of communications, told Newsweek that the senator's office has contacted Republicans about joining the bill. She noted that the pharmaceutical and health insurance industries have lobbied to prevent the banning of such ads. Bahr told Newsweek: "Over the past 25 years, the drug companies have spent $8.5 billion on lobbying. Today, they have some 1,800 well-paid lobbyists in Washington, D.C. – including former leaders of the Republican and Democratic parties.' "Unbelievably, that is more than three lobbyists for every member of Congress. During that same period, they have provided over $700 million in campaign contributions. And they are equal opportunity contributors. They contribute heavily to both Republican and Democratic candidates,' she added. Kennedy and Elon Musk have both openly backed the idea of banning pharmaceutical ads. "Let's get President Trump back in the White House and me to DC so we can ban pharmaceutical advertising," he wrote on X on November 3 last year. As he campaigned for president, Kennedy said he would sign an executive order on his first day in office banning pharmaceutical ads. Also in November 2024, Musk wrote on X: "No advertising for pharma." "The widespread use of direct-to-consumer advertising by pharmaceutical companies drives up costs and doesn't necessarily make patients healthier,' King said in a statement. 'The End Prescription Drug Ads Now Act would prohibit direct-to-consumer advertising of pharmaceutical drugs to protect people. This bill is a great step to ensure that patients are getting the best information possible and from the right source: their providers and not biased advertisements." Several Democratic senators have signed on to co-sponsor the legislation, including Connecticut Sen. Chris Murphy, Vermont Sen. Peter Welch, Oregon Sen. Jeff Merkley, and Illinois Sen. Dick Durbin, Sanders' office has stated.
