Study says strength training more effective than running for obesity, diabetes treatment

Strength training that repeatedly contracts and relaxes muscles may be more effective than aerobic exercise such as running in treating obesity and diabetes, according to a new study. A research team at the Fralin Biomedical Research Institute at the Virginia Tech Carilion School of Medicine recently published the findings in the Journal of Sport and Health Science. For the experiment, researchers induced obesity and type 2 diabetes in mice by feeding them a high-fat diet, then divided them into a strength training group and an aerobic exercise group. They built a “mouse-only strength training device” that required the animals to lift a weight to access food. Mice in the aerobic group were given free access to a running wheel. After eight weeks, both exercise groups showed significantly reduced weight gain compared with mice that did not exercise. They also saw a reduction in fat mass and improvements in fasting glucose and insulin sensitivity. The effects, however, were greater in the strength training group, including larger reductions in visceral and subcutaneous fat. Their fasting

Too beautiful to like? Study finds highly attractive influencers get fewer likes on social media

Click here for more articles by Kormedi.com. In an era when beauty standards on social media are becoming increasingly extreme, a new study suggests that being too beautiful might actually hurt one’s online popularity. A research team led by Andrew Edelblum at the University of Dayton and Abby Frank at the University of Oregon found that influencers perceived as “extremely attractive” received fewer likes and follows than those with moderate attractiveness. The team presented hundreds of participants with mock posts from fictional fitness influencers and analyzed their engagement patterns. The results, published on research-based news site The Conversation, describe the phenomenon as the “beauty backfire effect.” According to the researchers, highly attractive individuals are often viewed as less relatable or realistic in digital environments. They noted that this trend was especially pronounced in the fitness influencer category. The findings challenge the long-standing marketing principle of “sex sells.” While earlier studies suggested that physically attractive models in

Big noses, big findings? Japanese study suggests nose size may predict penis length

Click here for more articles by Kormedi.com. The old saying that “men with big noses are well-endowed” may have some scientific truth to it, according to a new Japanese study that found a stronger correlation between nose length and penis size than with hand or foot size. Researchers at Kyoto Prefectural University of Medicine analyzed autopsy data from 124 men, measuring various body parts and comparing them to each man’s “stretched penile length” — the length of the penis when gently pulled while flaccid. Their findings, published in the journal Basic and Clinical Andrology, suggest that nose size may indeed be a more reliable physical indicator. Men with larger noses had an average penile length of about 5.3 inches (13.5 centimeters), while those with smaller noses averaged about 4.1 inches (10.4 centimeters). The team said this difference was unrelated to height, weight, or age, implying that the relationship may be determined by developmental factors established before birth. Lead author Dr. Hiroshi Ikegaya said, “The link between nose size and penile length suggests t

Korea faces early flu surge, triggering medicine shortages as cases triple

Korea is grappling with an intense influenza season, with infections more than tripling from a year ago and showing pronounced peaks among school-aged children and adults over 50. Official data suggests a potentially severe season ahead. According to the Korea Disease Control and Prevention Agency (KDCA), the national outpatient influenza-like illness rate for the 43rd week of the year (Oct. 19-Oct. 25) climbed to 13.6 cases per 1,000 patients, a significant leap from the previous week’s 7.9 cases. The current rate decisively exceeds the national epidemic threshold of 9.1 cases and is nearly 3.5 times higher than the rate recorded during the same period 2024 (3.9 cases). The surge is most pronounced among younger age groups, with children aged 7 to 12 recording 31.6 cases per 1,000 outpatients and those aged 1 to 6 reporting 25.8 — the highest incidence rates this season. The dominant strain in circulation is influenza A (H3N2), the most prevalent and virulent type, known for its ability to infect both humans and animals and trigger global pandemics. By contrast, influenza B infects

Agriculture ministry unveils plan to eradicate classic swine fever in Korea by 2030

The agriculture ministry unveiled Wednesday its plan to make Korea free of classic swine fever (CSF) and minimize outbreaks of other major viral diseases affecting pigs, such as porcine epidemic diarrhea (PED), and porcine reproductive and respiratory syndrome (PRRS), by 2030. Under the road map, the country plans to establish infrastructure by 2027 for eradicating CSF, according to the Ministry of Food, Agriculture and Rural Affairs. To this end, the ministry will first replace the current CSF vaccine with a new marker vaccine, a special type of vaccine designed to let authorities distinguish animals that have been vaccinated from those that have been naturally infected with a disease, starting next year. The ministry will conduct detailed examinations of at least 25,000 animals at swine farms across the country each year to detect any potential outbreaks at the early stage, according to the ministry. It will check the progress of such efforts from 2028 to 2029 and apply for CSF-free status with the World Organization for Animal Health in 2030. Seoul will also work to minimize the outbre

Why you shouldn’t sit on grass in Korea without a mat this autumn

Health authorities are urging caution against tick-borne infectious diseases such as scrub typhus and severe fever with thrombocytopenia syndrome (SFTS), which occur most frequently in Korea during the months of October and November. The risk is particularly high during the harvest season and as outdoor activities like hiking and camping increase. Scrub typhus is caused by the bite of larval mites carrying the Orientia tsutsugamushi bacterium. According to the Korea Disease Control and Prevention Agency (KDCA), around 6,000 cases are reported each year, with infections peaking in autumn. After an incubation period of one to three weeks, symptoms such as chills, fever and headaches typically appear, but are often mistaken for the common cold. While early antibiotic treatment can lead to a full recovery, untreated cases may develop severe complications such as pneumonia, meningitis or kidney failure. Early diagnosis is critical. SFTS is transmitted by Haemaphysalis longicornis, commonly known as the Asian longhorn tick, which carries the SFTS virus. Roughly 200 cases are reported annuall

Depression, bipolar cases surge over 45% in 7 years

The number of people suffering from depression or bipolar disorders in Korea has surged, with cases of each of the conditions growing more than 45 percent over the past six years. According to government data disclosed on Thursday by the office of Rep. Kim Mi-ae of the main opposition People Power Party, the number of people diagnosed with depression rose from 752,976 in 2018 to 1,106,744 in 2024, a 47 percent increase. Meanwhile, treatment costs for the mental condition nearly doubled to exceed 761.5 billion won ($535 million), data from the National Health Insurance Service showed.

How too many cookies could hurt your mind: Everyday habits that quietly damage mental health

Click here for more articles by Kormedi.com. Seemingly harmless daily habits like spending hours on your phone or snacking on chips can quietly take a toll on your mental health, according to WebMD. Experts say the mind is just as sensitive to lifestyle choices as the body, and small changes can make a significant difference. Being inactive The human body is built to move. However, many people spend long hours sitting or lying down, particularly as they age. Studies show that increased sedentary time can worsen anxiety, depression and chronic pain. The key, experts say, is finding the right level of activity that suits you. For some, high-intensity workouts bring energy and pleasure, while others may prefer to start small with something simple like walking. Even committing to one day a week of movement can make it easier to build consistency over time. Chronic stress No one can live entirely free from stress — and in small doses, it can actually be helpful. Moderate stress keeps the mind alert and engaged. But when stress becomes chronic, it harms both body and mind. Irritability, anxiet

MAMAMOO’s Hwasa reveals she quit oily food for her comeback

Click here for more articles by Kormedi.com. MAMAMOO’s Hwasa has returned looking noticeably slimmer — and fans are eager to know her secret. The 30-year-old singer revealed she shed enough weight to reach the 40-kilogram range as part of preparing for her new single, “Good Goodbye.” Hwasa recently appeared on fellow MAMAMOO member Moonbyul’s YouTube channel, where the two discussed their fitness routines. Moonbyul said, “After taking a break, I started gaining weight — eating more, moving less, not dancing — and I ended up over 50 kilograms.” When she added that she was now managing her weight around 45 kilograms, Hwasa laughed and said, “You’re not that different from me,” hinting that she too had slimmed down to the mid-40-kilogram range. Known for her energetic stage presence and strong, healthy physique, Hwasa surprised fans by reappearing with a much leaner frame, cropped bob hairstyle and visible collarbones.
