Getting in more steps may prevent the leading cause of disability in the US, study says
Getting your steps in is good for your health, but it may also help keep you from being affected by disability later, new research has found.
Walking 100 minutes a day was associated with a 23% reduced risk of chronic low back pain, according to a study published Friday in the journal JAMA Network Open.
'This is an important finding because walking is a simple, low cost, and accessible activity that can be promoted widely to reduce the burden of low back pain,' said lead study author Rayane Haddadj, a doctoral candidate in the department of public health and nursing at the Norwegian University of Science and Technology, in an email.
An estimated 600 million people worldwide experience low back pain, which is considered the leading cause of disability, said physiotherapist Dr. Natasha Pocovi, a postdoctoral research fellow in health sciences at Macquarie University in Sydney. She was not involved in the research.
By 2050, the number of people with chronic low back pain is expected to grow to 843 million, according to the World Health Organization.
And yet prevention of low back pain is often overlooked in research and clinical practice, Pocovi added.
The results from this latest study show there is the possibility of using physical activity as prevention. Pocovi said the research also 'suggests that we don't need to complicate our exercise routines to protect ourselves against chronic low back pain.'
To investigate the connection between walking and back pain prevention, the research team analyzed data from more than 11,000 participants age 20 and older from the Trøndelag Health, or HUNT, Study in Norway.
Between 2017 and 2019, HUNT researchers asked study participants to wear accelerometers for seven days to track their walking patterns. The HUNT team then followed up from 2021 and 2023 and asked if participants experienced back pain, according to the new study.
People were divided into four groups: those who walked less than 78 minutes in a day, 78 to 100 minutes, 101 to 124 minutes, and more than 125 minutes.
The findings showed that as the amount of daily walking increased, the risk of chronic low back pain decreased, and preliminary evidence revealed moderate or brisk walking was more protective than a slow pace, Pocovi said.
There are reasons to have confidence in the study results, including the large sample size and the use of accelerometers instead of people reporting their own levels of physical activity, she added.
However, the walking data was only captured over one week, which might not be reflective of people's patterns over a month or year, Pocovi said.
The study is also observational, which means that while it can show associations, researchers can't say for sure that the walking caused reduced risk of low back pain.
Not only is low back pain a leading cause of disability –– it's also expensive. On average, people spend more than $30,000 on back pain-related costs over the five years after first diagnosis, according to an April 2024 study.
Easy, inexpensive changes that prevent chronic low back pain can make a big difference, Haddadj said.
The study wasn't able to address if walking 100 minutes straight had more, less or the same impact as accumulating that same amount of time in short bursts, Pocovi said.
But in most cases, unless there is an underlying medical condition, any amount of walking is better than none, Pocovi said.
'Start with short walking sessions, either by planning specific walks or finding small ways to integrate a brief stroll into your daily routine,' she said.
She likes to take stairs instead of the elevator or walk to a coffee shop a little farther from her home, Pocovi said.
'The key is to gradually increase your walking in a sustainable and enjoyable way,' she said in an email. 'Additionally, it can be helpful to have a friend, partner, or colleague join you for walks to keep yourself motivated and accountable.'
You can add walking as a way to spend time with friends in addition to dinner and drinks, CNN fitness contributor Dana Santas, a certified strength and conditioning specialist and mind-body coach in professional sports, said in a previous article.
And if you want to move past getting a couple of extra steps and get more physical activity, you can still start small and build your way up, Santas said. Some workouts can even be completed from the comfort of your couch while watching an episode of your favorite TV show, she added.

What Happens to Your Cholesterol When You Walk Every Day
Reviewed by Dietitian Maria Laura Haddad-Garcia Key Points Walking daily is one of the simplest low-barrier ways to support your overall heart health. Walking may help lower your LDL cholesterol and triglyceride levels and raise HDL cholesterol levels. Using weights, tracking your steps and walking post-meal are ways to make walking more effective. Trying to lower your cholesterol and support your heart health without hitting the gym? The good news is that you don't need a grueling fitness routine to make a difference in your cardiovascular health. Walking every day is a simple and accessible habit that can help improve your blood lipids (triglycerides, LDL or 'bad' and HDL or 'good' cholesterol levels) and protect your cardiovascular system in the long run. Why does this matter? 'High cholesterol is a major modifiable risk factor for the development of coronary artery disease,' says Bradley Serwer, M.D. 'By managing your cholesterol levels, you can potentially avoid or minimize heart attacks, strokes or peripheral vascular disease.' Your triglyceride levels are important, too. High triglycerides can happen on their own, but they can also go hand-in-hand with cholesterol levels, increasing your risk for heart disease. The Benefits of Walking for Cholesterol Daily walking delivers a range of benefits for cholesterol management and heart health. Here's an in-depth look at how it works. Lowers LDL Cholesterol When we talk about 'bad' cholesterol, we're referring to low-density lipoproteins or LDL, a waxy substance that can build up in your arteries. 'Elevated LDL increases the risk of heart attack and stroke by promoting plaque in critical vessels, particularly those of the heart and brain,' explains Alan Rozanski, M.D.. Research shows that for women with overweight or obesity, walking regularly for at least four weeks slightly lowers total cholesterol and 'bad' LDL cholesterol by about 7 mg/dL. Another study conducted on men found that consistent, moderate exercise for 12 weeks reduced LDL cholesterol by 5% to 7%. At the same time, more research on both men and women, ages 40 to 65, found that walking for three months or more produced mixed results, with some studies finding changes in cholesterol and triglyceride levels while others did not. While the effects may vary, incorporating regular walking into your routine is a simple and accessible way to support overall heart health. Supports Healthy HDL Cholesterol High-density lipoprotein (HDL) is often called the 'good' cholesterol because it removes cholesterol, protects against harmful oxidation, reduces inflammation and may help prevent blood clots. Higher levels of HDL are linked to lower risks of heart disease according to some (but not all) data. 'Aerobic activities such as walking help raise your high-density lipoprotein, HDL,' shares Serwer. Research shows that beyond just changing the numbers, exercise helps HDL particles mature and function better. Helps Lower Triglycerides Triglycerides are a type of fat in your blood, and elevated levels are another risk factor for cardiovascular disease. The good news? Walking is an effective way to lower them. During physical activity, your muscles use triglycerides as an energy source. Participating in physical activity, like walking, has been linked to reduced triglyceride concentrations in some studies. Supports Better Weight Management Walking is one of the simplest and most effective ways to support weight loss. It burns calories, supports metabolism and helps maintain lean muscle mass, all of which contribute to shedding extra pounds. Plus, it's an accessible and low-impact activity that can be easily incorporated into daily routines, making it a sustainable choice for long-term weight management. Carrying excess weight is closely linked to a range of heart-health concerns, including high cholesterol levels. People who carry extra body fat, particularly around the abdomen, tend to have higher LDL cholesterol levels. By making walking a regular habit, you can take a proactive step toward managing your weight and protecting your heart health. Helps Spark a Positive Feedback Loop Walking can also inspire a ripple effect of healthier choices. 'Walking can spark a positive feedback loop. As people become more active, they tend to feel better and adopt healthier habits—like improved eating—which further supports cholesterol management. That's why doctors often encourage movement as a starting point for lifestyle change,' explains Rozanski. This initial step toward activity often lays the groundwork for broader lifestyle improvements. By supporting energy levels and possibly improving mood, walking can make it easier to embrace other heart-healthy habits. Whether it's preparing more nutritious meals, getting better sleep or feeling motivated to try new activities, these changes work together to enhance overall health. Walking, therefore, isn't just exercise; it can be a catalyst for long-term, positive transformation. How Much Walking Do You Need? The Centers for Disease Control and Prevention recommends at least 150 minutes of moderate-intensity physical activity per week, which breaks down to about 30 minutes a day, five days a week. Brisk walking (about 3 to 4 miles per hour) fits the bill perfectly. If possible, aim for even more; 300 minutes weekly is linked to even greater heart benefits. 'But for the 25% of people who get no exercise at all, that can feel out of reach. The encouraging news is that even short bouts—like brisk five-minute walks—canimprove health,' says Rozanski. If you want to maximize results, adding some intensity can help. Try integrating inclines, walking at a faster pace, or even intervals where you alternate between slow and brisk walking. Tips to Make Walking Work for You Walking is simple, but a few tweaks can make it even more effective. Here are practical tips to make your daily walks count: Walk after meals to help with lipid metabolism. A 10- to 15-minute walk after eating can aid digestion and improve cholesterol processing. Add inclines or use hand weights for added cardio benefits. Walking uphill or using light weights engages more muscles and burns more fat. Track your steps with a pedometer or app to stay accountable and motivated. Many people find the goal of 10,000 steps a day achievable and rewarding. Pair your walking with . Start your day with oatmeal or snack on walnuts post-walk to double down on heart-health benefits. Small changes compound over time, so feel free to adjust these tips to your routine. Our Expert Take It's official! Walking daily is one of the simplest low-barrier ways to support your overall heart health. It's easy to incorporate into your lifestyle, whether that's a morning stroll, a post-dinner walk or active errands around town. Remember, you don't need fancy equipment, a big time commitment or extreme workouts. All it takes is lacing up your shoes and stepping outdoors. Starting small (like a 10-minute daily walk) can lead to big results over time. Your heart doesn't care how fast you go, just that you keep going. The sooner you start, the sooner your body and mind will feel the benefits. Take that first step today; your heart will thank you tomorrow. Read the original article on EATINGWELL

Woman from Gaza evacuated to Italy in a 'state of severe physical deterioration' dies in hospital
MADRID -- A 20-year old Palestinian woman described as being in a 'state of severe physical deterioration' has died after being transferred to Italy for treatment, the hospital said Saturday. The patient was admitted to Pisa University Hospital late Wednesday and died on Friday. She was removed from the Gaza Strip as part of a humanitarian mission and arrived with a 'with a very complex, compromised clinical picture,' according to the hospital. She died after entering a respiratory crisis and subsequently going into cardiac arrest, it said in a statement. Hospital staff had performed tests and started supportive therapy before she died, the statement said. The woman, named by Italian media as Marah Abu Zuhri, had arrived in Italy with her mother. Italian Foreign Minister Antonio Tajani said almost 120 Palestinians — 31 patients and their families — had been flown to Rome, Milan and Pisa on three planes. In a post on X, Tajani said that it was the 14th medical evacuation of Palestinians that Italy had conducted since January 2024, and the largest. The hospital did not specify whether the woman had suffered from malnutrition, but said that she had arrived in a 'state of severe physical deterioration.' Eugenio Giani, leader of the Tuscan region, expressed his condolences Saturday for the woman's death. Earlier in the week, United Nations spokesman Stephane Dujarric said that starvation and malnutrition in Gaza were at their highest levels since the Israel-Hamas war began. The U.N. says nearly 12,000 children under 5 were found to have acute malnutrition in July — including more than 2,500 with severe malnutrition, the most dangerous level. The World Health Organization says the numbers are likely an undercount. Israeli Prime Minister Benjamin Netanyahu said last month no one in Gaza is starving. 'There is no policy of starvation in Gaza, and there is no starvation in Gaza," he said. U.S. President Donald Trump responded to Netanyahu's claim by noting the images emerging of emaciated people. 'I don't know,' Trump said when asked if he agreed with the Israeli leader's comment. 'I mean, based on television, I would say not particularly because those children look very hungry.' Over the past two weeks, Israel has allowed around triple the amount of food into Gaza than what had been entering since late May. That was after two and a half months when Israel barred all food, medicine and other supplies, saying it was to pressure Hamas to release hostages taken during its October 2023 attack that launched the war.

Blindsided by brutal AI chess bots? This one thinks like a human
For years, the game of chess has been seen as a litmus test for how far AI can go against the human intellect. When IBM's Deep Blue supercomputer beat reigning Chess world champion Garry Kasparov in 1997, it was deemed a pivotal moment. The Wall Street Journal called it 'one giant leap backward for mankind.' It hasn't been a total route for humanity, however. Just a month ago, Norwegian chess grandmaster Magnus Carlsen beat ChatGPT in a chess game without losing a single piece. Interestingly, the AI bots are fighting, too. Earlier this month, ChatGPT (backed by OpenAI's GPT-o3 reasoning model) beat Grok, an AI chatbot developed by Elon Musk-led xAI, in a chess tournament. Recommended Videos But how does an average chess-loving person fare against AI bots at chess? Well, it's frustrating. One of the most recurring themes you will see on chess forums is that bots play 'differently from humans.' Of course, when you're playing against a chess computing bot like Stockfish 16 that can assess over ten million positions per second, not many players stand a chance. On the other hand, some seasoned players say beating chess bots is easier because they follow a pattern, and that one must know how to survive the initial assault to beat them. But at the end of the day, AI bots don't play by conventions. A researcher at Carnegie Mellon University has now come up with a less alien solution – an AI chess bot that plays like a human. Say hello to Allie The bot named Allie is the brainchild of Yiming Zhang, a PhD candidate at the Language Technologies Institute (LTI) in CMU's School of Computer Science. Interestingly, Zhang found himself eager to play chess after watching Netflix's popular series, 'The Queen's Gambit.' But soon after dipping into the world of online chess, he found himself frustrated by chess bots. After playing against them, he realized that these bots play unnaturally. Moreover, the underlying tactics behind a chess engine often make it nearly impossible to beat them, thanks to their training, which involves winning at all costs by doing increasingly complex calculations. That's where Allie differs from your average chess-acing bot. It has been trained on 91 million transcripts of chess games played between humans. As a result, the way it contemplates moves, makes attacking advances, and defends positions feels like an average human player. 'Allie is trained on log sequences of real chess games to model the behaviors of human chess players across the skill spectrum, including non-move behaviors such as pondering times and resignations,' says the research paper. During evaluations, researchers found that Allie actually 'ponders' at critical situations in the game. Go ahead and test your mettle The fact that Allie has been trained to think like a human doesn't mean it's a weak player. Far from it, actually. It can hold its fort against everyone from amateurs to grandmasters. 'Against grandmaster-level (2500 Elo) opponents, Allie with adaptive search exhibits the strength of a fellow grandmaster, all while learning exclusively from humans.' Since being deployed publicly, it has amassed more than 11,500 online chess games on the online platform Lichess, where you can also try your skills against it. So far, it has over 6,500 victories against human players, lost just over 4,000 games, and more than 500 battles have ended in a draw. 'For beginners, it's not interesting or instructive to play against chess bots because the moves they make are often bizarre and incomprehensible to humans,' Zhang explains. Interestingly, Allie is completely free and open-source, which means other researchers can build atop it. Do keep in mind it's only accepting invites for Blitz games. Moreover, if you want to learn how the human-like AI chess bot makes its moves before going against Allie, you can watch it in action versus other human players at Lichess. And if you want to take a peek at the code, head over to the GitHub repository.
