How Quitting Smoking Can Quickly Lower Risk Of A-Fib
Smokers who make the decision to quit will experience immediate health benefits, including a rapid reduction in their risk of atrial fibrillation (A-Fib), according to new research published in JACC: Clinical Electrophysiology. The study, conducted by Dr. Gregory Marcus, a cardiologist at the University of California, San Francisco, offers compelling evidence for smokers to quit, showing that it’s never too late to avoid the damaging effects of smoking on heart health.
Dr. Marcus, the senior author of the study, emphasized that A-Fib can be prevented even in individuals who have smoked for years. "The findings provide a compelling new reason to show current smokers that it’s not too late to quit, and that having smoked in the past doesn’t mean you’re ‘destined’ to develop A-Fib," Marcus explained. "Even for the current and longtime smoker, A-Fib can still be avoided."
"There’s strong evidence that smoking increases the risk of A-Fib," Marcus said. "But the benefits of quitting smoking have been less certain." With this in mind, his team sought to determine whether quitting could significantly lower a person’s risk of developing A-Fib, or if the risk would remain the same.
The research team analyzed data from over 146,700 current and former smokers, tracking their smoking habits and health over a 12-year period using data from the UK Biobank database. The results were promising: former smokers had a 13% lower risk of developing A-Fib compared to current smokers, while those who quit during the study saw an 18% reduction in their risk.
"This is likely a testament to the potency of reducing atrial fibrillation risk pretty shortly after quitting," Marcus said in a statement from the American College of Cardiology.
The findings highlight the importance of quitting smoking, not only for general health but specifically for reducing the risk of serious heart conditions like A-Fib.
Quitting smoking is one of the most effective ways to lower the risk of A-Fib and improve overall heart health. While it can be challenging, the benefits of quitting are clear and immediate. Here are some tips to help you quit smoking successfully:
1. Choose a specific date to quit smoking and stick to it. Prepare yourself mentally and physically for this change.
2. Reach out to family, friends, or a support group to help keep you accountable. Sharing your goals with others can provide encouragement.
3. Options like nicotine patches, gum, or lozenges can help ease withdrawal symptoms and reduce cravings.
4. Identify situations that make you want to smoke, such as stress or social gatherings, and find healthy ways to cope with them.
5. Regular exercise can help distract you from cravings and improve your mood during the quitting process.
6. Drinking water can help flush nicotine out of your system faster, reducing cravings.
7. Activities like yoga, meditation, or deep breathing exercises can help manage stress, a common trigger for smoking.
Quitting smoking offers immediate and significant benefits, particularly in reducing the risk of atrial fibrillation. The latest research provides smokers with more motivation to quit, showing that it's never too late to take control of their heart health.

The US Centers for Disease Control and Prevention (CDC) has confirmed that the Salmonella outbreak that infected 34 people in 13 states in the country is linked to backyard poultry.
The CDC, in its latest report, noted that backyard poultry, like chickens and ducks, can carry Salmonella germs even if they look healthy and clean. To date, no deaths have been associated with this outbreak, which started on February 26 and lasted up to March 31. However, 13 people have been hospitalized, the federal agency said.
Notably, the CDC analysis revealed that the Salmonella strain may be resistant to the antibiotic fosfomycin. Samples from eight of those patients showed there could be resistance to other antibiotics commonly used in Salmonella infections.
Michigan has the most cases, with six, followed by Wisconsin and Ohio, each of which has five cases.
Indiana, Kentucky, and Maine each have three cases. Florida, Illinois, Mississippi, New Hampshire, and Tennessee have each confirmed a single case.
Forty-one percent of case-patients in this outbreak are under the age of 5 years, and of the 29 people interviewed by investigators, 23 (79%) reported contact with backyard poultry in the days prior to illness.
“Children younger than 5 years old shouldn't handle the birds (including chicks and ducklings) or anything in the area where the birds live and roam. They are more likely to get sick from Salmonella,” the CDC said.
“Of 14 people who reported owning backyard poultry, 13 (93%) bought or obtained poultry since January 1, 2026,” the CDC said. “People reported getting their poultry from various places, including agricultural retail stores.”
The CDC said it will continue to investigate the hatcheries associated with cases.
The CDC also advised businesses to
As per the US Food and Drug Administration (FDA), Salmonella is a group of bacteria that can cause gastrointestinal illness and fever called salmonellosis. It can be spread by food handlers who do not wash their hands and/or the surfaces and tools they use between food preparation steps. It can also happen when people consume uncooked and raw food. Salmonella can also spread from animals to people.
The FDA notes that people who have direct contact with certain animals, including poultry and reptiles, can spread the bacteria from the animal to food if hand washing hygiene is not practiced.
Pets, too, could spread the bacteria within the home environment if they eat food contaminated with Salmonella.
Most people infected with Salmonella develop diarrhea, fever, and stomach cramps 6 hours to 6 days after being exposed to the bacteria.
The illness usually lasts 4 to 7 days, and most people recover without treatment.
In some people, the illness may be so severe that the patient is hospitalized.
Children younger than 5, adults 65 and older, and people with weakened immune systems are more likely to have severe illness.

US President Donald Trump-backed decision by the Centers for Disease Control and Prevention (CDC) to stop recommending giving infants a dose of the hepatitis B vaccine within 24 hours after birth is likely to lead to hundreds more infections, deaths, and millions of dollars in higher costs, according to new research.
The research, published in JAMA Pediatrics, comes as federal vaccine advisers to Health Secretary Robert F. Kennedy Jr. voted in December 2025 to reverse the long-standing recommendation to delay the first shot until at least two months of age for infants born to mothers who test negative for the virus.
While pediatricians, public health experts, and dozens of medical groups warned that it could harm children and their families, the new JAMA studies modelled the potential impact of the policy.
The first study estimated that delaying the first hepatitis B vaccine dose by two months for babies born in a single year to mothers who tested negative — about 80 percent of the 3.6 million US births annually — would increase lifetime health-care costs by at least $16 million, The Washington Post reported.
If vaccination were delayed by seven months, it would cost an additional $19.8 million.
The second study modeled what would happen if only 10 per cent of babies born to unscreened mothers received a birth dose; an additional 628 babies would get infected.
“One of the most concerning implications is how many more infected Hep B babies will we see,” said co-author Rachel Epstein, a pediatric and adult infectious diseases clinician at Boston Medical Center.
“A universal birth dose helps prevent a substantial number of infections in babies of a lifelong condition that we do not have a cure for,” she added.
Since 1991, all infants born in the US have received the first dose of hepatitis B vaccine within 24 hours of birth, a strategy that led to close to a 99 percent decline in infections among children.
Calling the universal birth-dose policy "a safety net", public health and medical experts noted that nearly 15 percent of pregnant women miss recommended hepatitis B screening. More than half of those who test positive do not receive appropriate follow-up care.
Delaying the initial dose also decreases the likelihood that a child will complete the three-shot series needed for full protection, hepatitis experts have said.
The authors argued that the CDC advisory panel departed from standards established for over three decades and failed to weigh key evidence.
“We noticed that the committee did not have the evidence they needed to inform their decision,” co-author Eric Hall, an assistant professor of epidemiology at Oregon Health and Science University, was quoted as saying to The Post.
“But this group kind of blew past all that and didn’t make any effort to fill the evidence gaps that they might have had. They just went ahead anyway.”

What is Hepatitis B?
Hepatitis B is a viral infection that affects the liver. It is highly contagious and spreads when blood, semen, or other bodily fluids from a person who carries the virus enter the body of someone who is not infected.
Hepatitis B can also pass from an infected mother to her baby during childbirth, whether through a vaginal delivery or a C-section. It is the most common route of transmission.
Vaccination is the most reliable way to prevent hepatitis B. The shots offer strong protection in infancy and continue to shield individuals well into adulthood.
Babies usually receive a three-dose series. A scientific review by the Vaccine Integrity Project found that 95 percent of healthy infants develop enough immunity after the third dose. The vaccine also lowers the risk of infection by nearly 70 percent in babies born to mothers who have hepatitis B.
You must check a watermelon for signs of adulteration before eating the fruit. (Photo credit: AI generated)
A biryani feast followed by a serving of watermelon proved deadly for a family of four in Mumbai on Sunday. The incident was reported from the Pydhonie area, where an entire family passed away after eating biryani for dinner and some watermelon before calling it a night. They had watermelon around 1.00 am or 1.30 am, and their condition started to deteriorate around 5.00 am. They all experienced diarrhoea and nausea and eventually passed away. The mystery now remains: was it a case of accidental watermelon poisoning or something else? Abdullah Dokadia (40), his wife Nasreen Dokadia (35), and their two daughters, Ayesha (16) and Zainab (13), lost their lives, and the police are currently suspecting it to be a case of food poisoning. But can eating watermelon really kill you? Let us find out.
Watermelon is a popular summer fruit that people enjoy eating during the hotter months. It is 70 per cent water, highly hydrating, and also beneficial for weight loss. However, going overboard is discouraged by doctors, as overeating or consuming adulterated watermelon can lead to abdominal discomfort and digestive distress. Watermelon-related food poisoning can occur because of E. coli or salmonella infections. It can cause rapid dehydration, diarrhoea, cramps, fever, weakness, and, in extreme cases, even death.
Dr Aarti Ullal, Physician and Diabetologist at Gleneagles Hospital, Parel, in an interaction with Health and Me, said, “Eating too much watermelon may lead to bloating, stomach discomfort, or loose motions, mainly because of its high water and natural sugar content. In some individuals, especially those with sensitive digestion, it can also cause acidity or mild cramps and disturb their peace of mind.”
Dr Ullal also stated that watermelon poisoning can occur when the fruit is contaminated with pesticides, chemicals, or bacteria due to poor handling or improper storage. The symptoms may include nausea, vomiting, abdominal pain, diarrhoea, and weakness. These are typically short-term digestive issues but may require medical attention if severe or if they interfere with daily routine. However, questions also arise regarding watermelon allergies. Watermelon allergy is rare and may cause itching in the mouth, swelling, rashes, or stomach upset soon after consumption.
To check if a watermelon is adulterated, look for an unnaturally bright red colour, cracks, a chemical smell, or an overly soft texture. Always wash the outer surface, as it may contain pesticides or chemicals, before cutting. Make sure to buy from trusted sources to avoid any health issues. Watermelon is safe and healthy to consume, but moderation and proper hygiene are key.
Conclusively, it can be said that eating a watermelon specifically should not cause deaths. However, if you bring the fruit home, it is advised to check it for signs of adulteration before consuming. It helps eliminate the possibility of side effects, just in case. However, if you experience food poisoning-like symptoms, consult a doctor immediately.
