You know that you need to watch your weight to lower your risk for heart disease, but that is far from the whole story. It is possible to be overfat without being overweight, meaning that you’re storing fat within your body even though the scale says you’re at a normal weight. And that distinction is key when it comes to heart health. For decades, doctors have measured a patient’s body mass index, or BMI, as a way to determine the heart disease risk associated with obesity. (There are even online calculators that let you figure out your BMI on your own.) Basically, BMI determines the percentage of fat in your body related to your height and weight. But some evidence shows that the calculation may misclassify up to 50% of those at risk of heart disease from excess fat. That’s because fat is not all the same. Fat stored around the belly, called visceral fat, is associated with insulin resistance and other metabolic abnormalities. Evidence shows that someone with a large waistline — over 40 inches for men and 35 inches for women — is more at risk for heart disease than someone with a smaller waist, even if they have the same BMI. Who’s most at risk? There are genetic components that indicate that white men, black women and people from India and South… read on >

(HealthDay News) — For folks with weak vision, eyeglasses, contact lenses, medicine and surgery may improve sight, says the National Eye Institute. Difficulty reading, matching colors and recognizing faces are common signs of weak vision. If you have vision loss, the institute stresses the need for a support team. Having a primary eye care professional and an optometrist or opthalmologist who specializes in weak vision is important. With your team, you can discuss options for support services, adaptive devices and vision rehabilitation. The institute encourages people with weak vision to be their own healthcare advocate. Remember to explore options, learn about your condition and ask questions.

(HealthDay News) — Facial wrinkles can be caused by aging, smoking and sun damage, says Cleveland Clinic. Though there are treatment options for wrinkles, it’s best to prevent them before they develop. Cleveland Clinic mentions these ways to prevent wrinkles: Apply sunscreen every day as part of your morning routine. Avoid products that are harsh on the skin. Find gentle moisturizers. Consume less sugar and refined carbohydrates. Get fresh air. Avoid environmental pollutants, such as soot and exhaust. Do your best to get six-to-eight hours of sleep each night. Include healthy fats in your diet, such as olive oil, nuts and avocado. If you smoke, quit.

(HealthDay News) — Many minor injuries can be treated at home by following a few guidelines, says the University of California. But for animal bites, deep cuts or wounds that bleed excessively, you should always see a doctor. The school mentions these do’s and don’ts of home care for minor wounds: Do irrigate the wound with water, gently wash and pat dry. Do apply petroleum jelly to exposed wounds, then cover with a bandage. Do cleanse the wound daily with soap and water. Don’t forget to apply sunscreen after the wound has healed to control scarring. Don’t apply a topical antibiotic. Don’t douse minor wounds with antiseptics.

With the arrival of winter, it’s time for skiing, sledding and ice skating, but it’s also when snow blindness can strike. Snow blindness is like a sunburn in the eyes. It’s caused by the same UV rays that give you that summer tan. In the case of snow blindness, the rays are reflected off the snow and into your eyes, explained experts from Ohio State University’s Wexner Medical Center. The cornea is the outer dome of the eye. It is covered by a thin layer of cells called the epithelial layer. UV light can burn this layer just as it burns your skin. UV burns to the cornea are called photokeratitis. Inflammation of the epithelial layer can result in blurred vision. When this happens after being outside on a bright snowy day, it is commonly referred to as snow blindness. Snow blindness can cause your eyes to feel burning, itching, stinging or intense pain. The same condition can result from being on the water or a beach as UV rays are reflected off the water or sand. Photokeratitis can also occur at high elevations where less UV light is absorbed by the atmosphere, the experts noted in a medical center news release. The best way to protect yourself is to use UV-light protective eyewear, the Ohio State team said. This can be either sunglasses or… read on >

As if the news on vaping wasn’t bad enough, a new study suggests that e-cigarette users are also at significantly higher risk of chronic lung diseases such as asthma, bronchitis, emphysema and COPD. Those risks rose even higher if vapers also smoked tobacco, researchers said. “What we found is that for e-cigarette users, the odds of developing lung disease increased by about a third, even after controlling for their tobacco use and their clinical and demographic information,” said study senior author Stanton Glantz. He directs the Center for Tobacco Control Research and Education at the University of California, San Francisco. In the new study, Glantz’s team tracked data on the cigarette and e-cigarette use of more than 32,000 U.S. adults, none of whom had lung disease at the start of the study. The researchers then recorded new lung disease diagnoses over the years 2013 to 2016. Those diagnoses included such common and debilitating illnesses as asthma, bronchitis, emphysema and chronic obstructive pulmonary disorder (COPD). “We concluded that e-cigarettes are harmful on their own, and the effects are independent of smoking conventional tobacco,” Glantz said in a UCSF news release. Current and former e-cigarette users were 30% more likely to develop chronic lung disease, while tobacco smokers had more than 2.6-times increased risk. For people who vaped and smoked, risks of developing a lung disease more… read on >

Losing weight might be a powerful weapon against breast cancer, a new study suggests. “Our results suggest that even a modest amount of sustained weight loss is associated with lower breast cancer risk for women over 50,” said study author Lauren Teras, a senior principal scientist with the Behavioral and Epidemiology Research Group at the American Cancer Society (ACS). “These findings may be a strong motivator for the two-thirds of American women who are overweight to lose some of that weight. Even if you gain weight after age 50, it is not too late to lower your risk of breast cancer,” Teras said in an ACS news release. One breast cancer expert agreed. “Perhaps women that lost weight made a conscious effort to live a healthier lifestyle overall, which may have included a healthy diet, more exercise and less drinking, all of which contribute to a lower risk of cancer,” said Dr. Stephanie Bernik, chief of breast surgery at Mount Sinai West in New York City. “In the United States, where obesity is the norm, hopefully studies like this will help women understand the importance of healthy living.” Teras’ team analyzed data from more than 180,000 U.S. women, 50 and older, who took part in 10 studies. Their weight was assessed periodically over about 10 years: at study enrollment; about five years later; and again… read on >

Playing sports may improve the brain’s ability to process sounds, a finding that could lead to new therapies for people who struggle with hearing, researchers report. “No one would argue against the fact that sports lead to better physical fitness, but we don’t always think of brain fitness and sports,” said study senior author Nina Kraus. She’s a professor of communication sciences and neurobiology at Northwestern University, in Evanston, Ill. “We’re saying that playing sports can tune the brain to better understand one’s sensory environment,” added Kraus, director of the university’s Auditory Neuroscience Laboratory. The study included 495 female and male Northwestern student athletes and a control group of 493 age- and sex-matched non-athletes. The participants’ brain activity was monitored while they wore earbuds that delivered speech sounds. The athletes were more adept than those in the control group to tune out background noise to better process the speech sounds, according to the study published Dec. 9 in the journal Sports Health. That skill can be useful for athletes when they’re trying to hear a teammate or coach calling to them during a game. Kraus equated it to listening to a DJ on the radio. “Think of background electrical noise in the brain like static on the radio,” Kraus said in a university news release. “There are two ways to hear the DJ better: minimize… read on >

A cheap, century-old drug in most Americans’ medicine cabinets — aspirin — may come to the rescue for people suffering from migraines, a new study finds. While there are effective prescription medications, many migraine patients in the United States don’t have access to them due to limited access to doctors or good insurance, or high insurance co-pays, said researchers at Florida Atlantic University, in Boca Raton. Aspirin might often be a viable option for these patients, said the research team, who reviewed 13 studies of migraine treatment involving more than 4,200 patients. The investigators also looked at data on the prevention of recurrent migraine in tens of thousands of patients. The results suggest that giving a high dose of aspirin — 900 to 1,300 milligrams (mg) — when migraine symptoms set in is an effective and safe treatment for acute migraine. There’s also evidence that daily aspirin doses of 81 to 325 mg may be an effective and safe treatment for prevention of recurrent migraine, the team said. The standard “low-dose” aspirin pill, taken by millions of Americans to help lower heart risks, contains 81 mg. The bottom line: “Our review supports the use of high-dose aspirin to treat acute migraine as well as low-dose daily aspirin to prevent recurrent attacks,” senior author Dr. Charles Hennekens, professor and senior academic advisor at the university’s College… read on >

The holiday season can give you real headaches, but you can take action to prevent them, an expert says. To reduce stress, make plans well in advance and know your limits, advised Dr. Bing Liao, a neurologist at Houston Methodist. “The nature of the holiday season already increases stress levels, so finding small ways to reduce schedule stress can help ward off a headache,” Liao said in a hospital news release. “This can mean planning well in advance to avoid the hassle of making last minute travel plans, or deciding not to attend a party at the end of a long day.” Be sure you have an adequate supply or a refill of your prescription medications before the holidays, she advised. Missing doses or cutting back could trigger a headache or even serious side effects. “Don’t binge anything during the holidays — food, alcohol, or television,” Liao said. “We all know how a hangover can affect the brain, but most don’t realize that overeating can also trigger a headache. And having the next day off from work doesn’t mean you should stay up late watching holiday movies. The brain needs the same amount of sleep during the holidays as it does the rest of the year, so stick with your usual bedtime.” Running holiday errands can lead to skipped meals and dehydration, which can trigger… read on >
