The #1 Habit to Avoid for Better Heart Health, According to Experts
However, this habit may silently be raising our risk of heart disease.
Fortunately, there are easy strategies to help break the habit, no workout required.Heart disease is the leading cause of death in U.S. adults. While some heart disease risk factors like family history, sex and age are out of your control, others can be managed with a healthy diet and lifestyle. On the flip side, there are some habits we should avoid, say heart-health experts. And the biggest one is sitting too much.
Between desk jobs and catching up on our favorite TV shows, it's all too easy to spend most of our day sitting. In fact, roughly 1 in 4 American adults spend more than eight hours sitting every day. So, we asked the experts to share why too much time sitting is so problematic for heart health and what you can do about it. Here's what they told us.
Your heart works hard all day long to pump blood throughout your body. However, it doesn't do this job alone. Muscle contractions are also important for good circulation. 'Long periods of sitting slow circulation, which can increase blood pressure and lead to blood pooling in the legs,' says cardiovascular nutrition specialist Veronica Rouse, M.A.N., RD, CDE. When resting muscles aren't helping circulate your blood, your heart has to work harder to pump blood throughout your body. Over time, this may increase your risk of heart disease. That may be one of the reasons why research has found that people with sedentary jobs may be 34% more likely to die from heart disease than people who spend their workdays upright, says Rouse.
Being inactive is linked with weight gain and obesity, which puts you at a higher risk for heart disease, says Lisa Andrews, M.Ed., RD, LD. That's not the only reason you should be breaking up periods of sitting time with some physical activity. Missing out on physical activity also encourages the development of visceral fat, aka belly fat. Too much visceral fat can increase inflammation, which, in turn, can contribute to more weight gain—a vicious cycle that can be hard to break.
Another reason to get up and out of your chair is that inactivity may lead to the development of insulin resistance. When you have insulin resistance, your body is less responsive to insulin. This hormone normally shuttles glucose from your blood into your cells for energy. Trouble is, when insulin stops working effectively, blood glucose levels rise. Over time, this can lead to the development of type 2 diabetes and can eventually damage your blood vessels, increasing your risk of heart disease.
One review found that the more sitting time a person clocked each day, the higher their risk of insulin resistance. Regularly moving your body makes your muscles grab glucose from your blood to use for energy, potentially protecting you from heart troubles.
In addition to all the above adverse effects of sitting too much, too much sedentary time means you'll miss out on all the other positive things moving your body does for your heart. 'Physical activity directly improves nearly every cardiovascular risk factor,' says cardiologist Elizabeth Klodas, M.D. 'Even 20 minutes of walking a day helps lower blood pressure, reduces inflammation, improves blood sugar control and supports healthier cholesterol levels, all critical to reducing heart disease risk. More movement equals more protection.'
Sitting too much is a hard habit to break, but it can do so much good for your heart. If you are looking for more ways to give your heart some love, try these expert strategies:
Make Time for Exercise Snacks: 'Try exercise snacks, which are short bursts of movement throughout the day,' says Rouse. 'These mini movement breaks are easy to fit into daily routines and have been shown to improve insulin sensitivity and vascular health.' They're so powerful that research has found that taking a quick one-minute exercise snack every one to four hours throughout the day can help lower blood sugar and triglycerides and improve blood flow throughout the body. If you could use a reminder, Rouse suggests setting a timer to tell you it's time to get up and move.
Embrace the Mediterranean Diet: Following a healthy eating pattern can also go a long way in protecting your heart health. Andrews recommends the Mediterranean diet, which emphasizes heart-supporting fruits, veggies, legumes, whole grains, nuts, seeds and olive oil. It's so effective that research has found that it may cut the risk of dying from heart disease by nearly 50%.
Get Checked: When life gets busy, it's all too easy to skip (or cancel) routine doctors' visits. For the sake of your heart, make your annual checkup a priority. 'You can't feel high cholesterol or blood pressure, so it's important to get those numbers checked and address any risks early,' says Klodas.
Catch Those Zzz's: When it comes to heart health, diet and exercise are usually the first things that come to mind. However, making sure you get enough quality sleep at night could be just as important. Regularly getting less than seven hours of sleep is associated with a higher risk of heart disease. No wonder the American Heart Association lists sleep as one of their 'Life's Essential 8' foundational strategies for better heart health.
Between desk jobs, long commutes and unwinding in front of the TV, most of us spend way too much time sitting. Yet, it's silently raising our risk for heart disease. In fact, experts say avoiding too much time on your tush is the No. 1 thing to avoid for better heart health. Sitting too long can slow down blood circulation and may promote weight gain and insulin resistance. Plus, when you're sitting, you're missing out on the many benefits of physical activity. The good news is that even short one-minute movement breaks every hour or so can help counteract the effects of sitting. 'You don't have to be perfect ... just better,' says Klodas. 'Small, consistent changes can make a real difference, often in as little as 30 days.' So, set a timer on your phone to help you remember to get up and out of your chair for a quick movement break. Your heart will thank you for it.

Childhood vaccination rates fall for 5th straight year, CDC data shows
Childhood vaccination rates for the 2024-25 school year fell for the fifth year in a row, according to data from the Centers for Disease Control and Prevention (CDC) published Thursday. Vaccine coverage for shots that protect against measles, polio, chickenpox, whooping cough and hepatitis B have now been under 95% -- a threshold many experts consider herd immunity -- since at least the 2020-2021 school year. Exemptions for vaccines also hit a record high, increasing to 3.6% for the 2024-25 school year compared to 3.3% during the previous school year. The number of kindergarteners exempt from one or more vaccines was about 138,000. MORE: Members of CDC vaccine panel ousted by RFK Jr. say committee has 'lost credibility' "That gap, combined with concentrated pockets of exemptions, is exactly how sustained outbreaks gain a foothold," said Dr. John Brownstein, an epidemiologist and ABC News medical contributor. "Kindergarten vaccination rates are an early warning indicator. Persistent declines predict conditions for more frequent and larger outbreaks are already in place." Exemptions increased in 36 states, with 17 states reporting exemption rates exceeding 5%, according to the CDC data. Nearly all the exemptions were listed as non-medical, typically related to religious or personal reasons. "The surge in non-medical exemptions reflects a growing influence of misinformation and shifting policy. When these beliefs concentrate geographically, they erode the very network of immunity that protects all children," Brownstein said. An estimated 92.5% of kindergarteners were vaccinated with the polio vaccine as well as the measles, mumps and rubella vaccine, leaving an estimated 286,000 vulnerable to the diseases. It comes as the U.S. is seeing the highest number of measles cases since 1992, with dozens of outbreaks reported across the country, CDC data shows. About 94% of kindergartners were vaccinated against hepatitis B. Even fewer children were vaccinated against chickenpox and whooping cough with rates at 92.1%, according to the data. MORE: Medical groups sue HHS, RFK Jr. over 'unlawful' vaccine changes Last year saw a record level of whooping cough cases, with more than 35,000 cases reported -- roughly six times as many cases compared to 2023. Federal health officials in the Trump administration have also recently shifted messaging around vaccination, now pushing for personal choice -- advocating that parents should decide whether or not to immunize their kids. "Public health messaging has shifted in ways that place personal choice ahead of community protection. When federal leadership softens its stance on vaccination, it can accelerate hesitancy and legitimize non medical exemptions, further weakening population level immunity," Brownstein said. "As pediatricians, we know that immunizing children helps them stay healthy, and when everyone can be immunized, it's harder for diseases to spread in our communities," Dr. Susan Kressly, president of the American Academy of Pediatrics said in a statement. "By making sure all children can access immunizations before entering school with their classmates, children are best able to stay healthy to play, learn, and grow."

Hunger strike at Alligator Alcatraz reaches Day 9 as inmate protests conditions
A detainee at the Florida immigration detention center known as Alligator Alcatraz has been on hunger strike for at least nine days, the latest in a string of detainees to allege being mistreated at the prison in the Everglades. 'Since my life no longer belongs to me, it's up to them to decide whether I live or die,' detainee Pedro Lorenzo Concepción, 44, told El País from inside the facility. State officials run the Florida detention camp, housing migrants in a series of hastily assembled tents and chain link enclosures on a converted airstrip as they await federal immigration court and potential deportation by U.S. Immigration and Customs Enforcement. The Independent has contacted the Florida Division of Emergency Management, one of the state agencies overseeing the facility, for comment. Concepción, who came to the U.S. from Cuba in 2006 but lost his permanent resident status after going to prison, has been in detention since being arrested on July 8 after a check-in at a Florida Immigration and Customs Enforcement office, according to his family. The Independent has contacted ICE for comment. On July 22, he went on hunger strike and has collapsed multiple times inside Alligator Alcatraz. During the strike, he was taken to Miami's Kendall Hospital, according to his family, where he said he sat in handcuffs as doctors tried to get him to eat, but he refused. 'I don't want food, I refuse any treatment,' reads a document he signed about his protest, obtained by El País. 'I didn't even ask to be taken to the hospital, because I'm fighting for my family and all Cubans, and I belong where my people are, in prison, suffering the same hardship they are.' The Independent has contacted Kendall Hospital for comment. Concepción's wife said she's worried he could be deported back to Cuba without her or the couple's two children. 'In a minute, your life falls apart,' she told the paper. 'It's been 19 years of being together.' Concepción, who said he was shackled and left on a floor at Alligator Alcatraz for more than 10 hours upon his arrival, is not the only one to complain of alleged poor conditions at the facility, which federal officials say they plan to support with millions in reimbursement funds and use as a model for future detention centers. Other inmates say they have faced poor sanitation and other brutal conditions inside the facility, which sits in the middle of a sweltering swamp. 'They only brought a meal once a day and it has maggots,' Leamsy 'La Figura' Izquierdo, a Cuban artist who was housed at the facility, told CBS News. 'They never take of the lights for 24 hours. The mosquitoes are as big as elephants.' The facility is facing lawsuits on environmental and civil rights grounds, with lawyers accusing officials of largely barring them from being able to speak with detainees. Deportation flights for detainees held at the facility have begun, state officials announced last week. Earlier this month, Florida news outlets found that among those held at Alligator Alcatraz, only about one-third had a past criminal record, despite officials touting the prison as being designed to hold the worst of the worst.

Treatment Considerations for End-Stage COPD
This transcript has been edited for clarity. Hi, everyone. Dr Chandrasekaran here, and today I'm going to talk about end-stage COPD (chronic obstructive pulmonary disease). We commonly diagnose COPD based off one of three things. One being imaging, showing emphysema or bronchitis; one being pulmonary function tests that can show obstruction; and one being symptom-based. Together, these help us to stage, define, manage, and treat patients with COPD. Once they do reach end-stage COPD, this becomes a healthcare burden associated with increased hospitalizations. We manage these patients by making sure they are on triple-therapy inhalers, including a LAMA (long-acting muscarinic antagonist), LABA (long-acting beta agonist), and inhaled corticosteroids. In addition, we can add theophylline or roflumilast to help decrease hospital readmissions. Chronic azithromycin therapy, 250 mg three times a week, has been shown to decrease shortness of breath and recurrent hospital admissions. Prior to starting this, sensorineural hearing tests along with QTc must be done to make sure that they are not increasing or addition, noninvasive ventilation can help these patients, as they do suffer from sleep-disordered breathing, and help decrease the hypercapnia that these patients face. Long-term oxygen therapy needs to be considered for end-stage COPD, along with lung volume reduction surgery in a handful of patients that do qualify and endobronchial valves in patients who have emphysema and qualify for these mechanisms.
