(HealthDay News) — One in 25 U.S. drivers reports having fallen asleep while driving during the past month, the U.S. Centers for Disease Control and Prevention says. The first step to prevention is recognizing the symptoms of driving drowsy, the agency says, offering this list of warning signs: Yawning or blinking a lot. Having difficulty remembering the past few miles driven. Missing your exit. Drifting from your lane. Hitting a rumble strip on the side of the road.
Before heading out to shop this holiday season, steel yourself for an onslaught of tempting aromas that might lure you into a fast-food restaurant. Food-related cues, like the smell of burgers or eye-catching menu displays, stimulate brain activity. This tempts people to eat more, a new study finds. University of Michigan researchers conducted lab experiments with 112 college students. The investigators found that food cues made people feel hungrier and led to the consumption of 220 more calories compared with non-cue environments. “Food-related cues can make people want or crave food more, but don’t have as much of an impact on their liking, or the pleasure they get from eating the food,” said study lead author Michelle Joyner, a psychology graduate student. The results show that people need to be aware that food cues can increase how much they eat, the researchers said. “It is hard to avoid food cues in our current environment, but people can try some strategies to minimize their exposure by not going into restaurants and using technology to skip food advertisements in TV shows,” Joyner said in a university news release. The findings were published in the November issue of the journal Clinical Psychological Science.

Former professional football players are at increased risk for an enlarged aorta, which can lead to a life-threatening bulge in the artery, a new study reports. The aorta, the largest artery in the body, carries blood from the heart to the rest of the body. The short part of the aorta is called the ascending aorta. It rises from the left ventricle — the bottom left chamber of the heart — and supplies the coronary arteries with blood. Enlargement of the ascending aorta, called dilation, can increase the chances of a bulge. The bulge is known as an aneurysm. An ascending aorta that is more than 4 centimeters (1.6 inches) in diameter is considered to be dilated. The study included 206 former National Football League players and a control group of 759 other men older than 40. Compared with the control group, the former pro football players had significantly larger ascending aortic diameters. Nearly 30 percent of the ex-NFL players had an aorta wider than 4 centimeters, compared with only 8.6 percent of men in the control group. Even after the researchers adjusted for age, body mass and heart risk factors, former NFL players were still twice as likely as the control group to have an aorta wider than 4 centimeters. The findings were to be presented Wednesday at the annual meeting of the Radiological… read on >
Strength training needs to be part of every exercise plan, but you don’t have to join a health club to reap its benefits. You can create a state-of-the-art home gym, but an inexpensive approach will work just as well. First, pick out a 10-by-10-foot space where you can exercise without tripping over or bumping into anything. It doesn’t have to be a dedicated area as long as you can move any furniture out of the way when you’re ready to work out. Next, choose your equipment. The American College of Sports Medicine suggests starting with a few dumbbells or resistance bands plus a stability ball. If it’s in your budget, an adjustable bench adds variety to upper body workouts. Dumbbells are hand-held weights, available from 1 to 45 pounds each. Handle choice is key. You want some friction for a good grip, but also a comfortable feel. If buying a set, be sure there are weights you can lift now and weights you can work up to. If you’re short on storage space, try stretchy resistance bands. Bands come with different tensions appropriate for different muscle groups. Some are just lengths of material you wrap around your hands. Others have handles. Test both to see what you like best. It’s a good idea to have a trainer outline a home plan with exercises that target… read on >
(HealthDay News) — Snoring is not only an annoyance, but also a potential health concern. Chronic snoring may be associated with sleep apnea, which can lead to sleep deprivation and potential heart issues. The National Sleep Foundation says certain exercises may strengthen muscles surrounding the airways and help prevent snoring: Push the tip of your tongue against the roof of your mouth and slide the tongue backward. Repeat 20 times. Suck your tongue upward so that the entire tongue lies against the roof of your mouth. Repeat 20 times. Force the back of your tongue downward against the floor of your mouth while keeping the tip of your tongue in contact with your bottom front teeth.
(HealthDay News) — Not all snacks are bad for you, so it’s a good idea to avoid foods that are loaded with sugar and have virtually no nutritional value. The U.S. National Institute on Aging offers these healthier snack suggestions: Have an ounce of cheese with some whole-grain crackers, a container of low-fat yogurt or some low-fat popcorn. Gather a bowl of fruit for the kitchen or your living room coffee table. Keep a container of raw vegetables in the fridge. If you want some chips or nuts, don’t eat from the bag. This will avoid portion control issues.
Patients used to see doctors as kindly-but-firm professionals — experts who knew what they were talking about and whose advice should be heeded, even if it wasn’t necessarily welcome. But these days, people have become demanding health care consumers, and they don’t respond well when a doctor disagrees with them, a new study shows. The researchers found that two-thirds of patients arrive at their doctor’s office with a specific medical request already in mind — seeking a drug or a test or a referral. When their doctor turns down that request, they’re more likely to be offended and to trash the doctor on a patient satisfaction survey. Satisfaction scores plummet when doctors deny patients’ requests for nearly anything, but especially when patients have asked for a drug prescription or a referral, the study found. The problem for doctors is that their pay has become increasingly tied to their patient satisfaction scores, said the study’s lead researcher, Dr. Anthony Jerant. He’s a professor of family and community medicine with the University of California, Davis School of Medicine. “A lot of physicians are tempted to just acquiesce and give them the pain medication or give them the test, even though they know it’s really not that likely to be helpful,” Jerant said. “We really need to rethink reimbursing physicians partly on their satisfaction scores.” For this study,… read on >
Weight loss from dieting can slow the progression of knee arthritis in overweight people, according to a new study. But losing pounds from exercise alone will not help preserve those aging knees, the researchers found. Obesity is a major risk factor for painful knee osteoarthritis — degeneration of cartilage caused by wear and tear. Weight loss can slow the disease, but it wasn’t clear until now if the method of weight loss made a difference. Apparently, it does. “These results add to the hypothesis that solely exercise as a regimen in order to lose weight in overweight and obese adults may not be as beneficial to the knee joint as weight loss regimens involving diet,” said lead author Dr. Alexandra Gersing. Gersing made her comments in a news release from the Radiological Society of North America (RSNA). She’s with the University of California, San Francisco’s department of radiology and biomedical imaging. The study included 760 overweight or obese adults who had mild to moderate knee osteoarthritis or were at risk for it. The participants were divided into a “control group” of patients who lost no weight, and a group who lost weight through either a combination of diet and exercise, diet alone, or exercise alone. After eight years, cartilage degeneration was much lower in the weight-loss group than in the control group. However, that was… read on >
Motorcycle crashes are far costlier than car accidents, both in lives lost and in medical expenses, a new study shows. Canadian researchers found that the death rate from motorcycle crashes was five times greater than from car crashes, and the rate of severe injury was 10 times greater. That came with a six times greater cost to the health care system. Though the findings stem from an analysis of traffic accidents in the Canadian province of Ontario, the researchers said that similar patterns would likely be seen elsewhere. One reason: Motorcycles are inherently more risky because motorcycles lack the protections that cars provide. “It’s clear that it’s much more dangerous to ride a motorcycle than to ride in a car,” said lead researcher Dr. Daniel Pincus. But the study isn’t saying that motorcycles should be taken off the road. “A lot of people enjoy riding motorcycles, so we’re not saying the answer is to ban them from doing it,” said Pincus, who’s with the Institute for Clinical Evaluative Sciences, in Toronto. Riding simply should be made safer, he said. Kara Macek, a spokesperson for the Governors Highway Safety Association (GHSA), agreed. Universal helmet laws are one way, she said. In the United States, only about half of states require helmets for all motorcyclists, according to the GHSA. “Just telling people to wear helmets is not… read on >
There’s no evidence to support the notion that people who get the flu vaccine every year somehow “weaken” their immune system over time, researchers say. In fact, annual vaccination seemed tied to stronger immune cell activity, according to the Norwegian research team. That’s even true for years where the flu shot is a poor match for flu viruses actually circulating, as happened in the 2016-2017 season, the findings suggest. The study was led by Rebecca Cox of the University of Bergen’s department of clinical science. Her group tracked the immune system health of 250 health care workers. Some of the participants got the flu shot beginning in 2009 and then every year thereafter, while others only got the shot in 2009, but then no shot between 2010 and 2013. Immune system antibodies that showed activity against the flu “persisted above the protective levels in [the] repeatedly vaccinated adults,” the team reported. Specifically, immune system CD4 and CD8 T-cells — which target viruses — had more disease-fighting capability “after multiple annual vaccinations” than those in people who didn’t get the yearly flu shot, the investigators found. The research team noted that even though the flu shot has been in use for more than half a century, there have been very few studies that have tracked the immune system health of recipients in such a rigorous way.… read on >
