Why dog owners seem to have healthy hearts
Research we're watching
Having a dog often means taking daily walks, a habit that helps stave off heart disease. But that might not be the only reason dog owners have healthier hearts, according to a new study.
The nearly 1,800 participants had no history of heart disease in 2013 when the study began. Researchers scored them based on the American Heart Association's "Life's Simple 7" factors: body mass index, diet, physical activity, smoking status, blood pressure, blood sugar, and total cholesterol. Then they compared the scores of people who owned any pet to those who did not own pets, as well as the scores of dog owners with owners of any pet or no pet.
Optimism: Good for your heart?
Research we're watching
People with a positive outlook on life seem to be less likely to experience serious heart-related problems, according to a review published Sept. 27 by JAMA Network Open.
The study pooled findings from 15 studies involving a total of more than 220,000 people. After a follow-up period lasting an average of nearly 14 years, researchers found that optimism was associated with a 35% lower risk of angina, heart attack, stroke, or death from cardiovascular causes. That benefit held even when they considered studies that took into account depression, physical activity, and other possible confounding factors.
Get fit to function
These three exercises can help make functional fitness part of your regular routine.
As part of everyday living, you spend a lot of time bending, reaching, lifting, twisting, turning, and squatting, without even thinking about it. These movements show up in everything from carrying groceries, to playing with your grandkids, to just checking if the coast is clear when you back out of the driveway.
The ability to do these ordinary activities and movements is called functional fitness, and it can determine how active, healthy, and independent you are as you get older.
Outrunning the risk of dementia
Even if dementia runs in your family, smart lifestyle changes can help you improve your chances of staying ahead of it.
There are many things you can change about your life, but unfortunately, your genes are not among them. For better or worse, you are dealt a specific genetic hand when you are born. But that does not mean you are defenseless.
Take dementia, for example. If this cognitive disorder runs in your family, new research suggests there are ways to perhaps avoid the same fate.
Muscle pain from exercise? Protein drinks offer little help
In the journals
Downing a protein drink after a workout is often seen as the best way to reduce muscle soreness and speed up recovery. However, this may not be the case, suggests a study published online Aug. 21, 2019, by Human Kinetics.
Researchers found that high-protein drinks did not increase the rate of muscle recovery following resistance training when compared with a carbohydrate-only drink. They recruited 30 men who had at least one year of resistance training experience. The men performed a prescribed workout and afterward had either a whey protein hydrolysate-based drink, a milk-based drink — both of which contained 32 grams of protein — or a carbohydrate-only drink. (All the beverages had the same amount of calories.)
Your heart’s best friend may be dog ownership
In the journals
Adopt a dog and get a healthier heart. That's the conclusion of a study published in the September 2019 issue of Mayo Clinic Proceedings.
Researchers looked at 1,769 people ages 25 to 64 with no history of heart disease. Participants' overall cardiovascular health was assessed based on several health markers, such as body mass index, diet, physical activity, smoking, blood pressure, blood sugar, and total cholesterol levels.
Too much vitamin D may harm bones, not help
A study shows that, for many people, less is more when it comes to vitamin D.
There's no question that vitamin D can help build strong bones. But there may be a sweet spot when it comes to how much.
A study published in the Aug. 27 issue of JAMA found that, compared with people who took moderate amounts of vitamin D, adults who took large amounts daily not only didn't see additional gains in bone density, but in some cases ended up worse off.
How can I reduce symptoms from my winter allergies?
Ask the doctors
Q. I have terrible allergies every winter. What can I do to make them more tolerable this year?
A. Unlike fall or spring allergies, which are often responses to outdoor allergens, such as pollen or ragweed, most winter allergies are triggered by substances inside your home. Common indoor allergens include dust mites, mold, and pet dander, and they can prompt a host of symptoms, from a runny nose and sneezing to a sore throat and itchy eyes. While these indoor allergens are present year-round, allergies can flare up in the winter because you're cooped up in the house with the windows closed. Your home's furnace may also be circulating these substances through the air once the heat kicks on.
Boost your activity level in small bites
Incorporating brief spurts of high-intensity physical activity throughout your day can help you move to the next fitness level.
If you're not very active but looking to move more, a new strategy might help you get going. Called high-intensity incidental physical activity, or HIIPA for short, it's a new take on high-intensity interval training (HIIT) — only you might find yourself vigorously pushing a vacuum instead of going for a run.
HIIPA (not to be confused with the HIPAA health care privacy rule) is a term coined in an editorial published online Sept. 3 by the British Journal of Sports Medicine. It borrows from the idea behind HIIT, which is a workout that alternates between high-intensity and low-intensity activity. But instead of performing these high-intensity intervals during exercise, HIIPA encourages otherwise sedentary people to add a few moderately strenuous physical activities during the course of their regular day. Anything that raises your heart rate counts — walking up a flight of stairs instead of taking the elevator, carrying in a load of groceries, or doing some heavy cleaning around the house. The editorial's authors, a team of international experts, say the goal is to perform an activity that gets you a little out of breath.
Is plastic a threat to your health?
Heating plastics in the microwave may cause chemicals to leach into your foods.
Plastic is everywhere. It's in bowls, wraps, and a host of bottles and bags used to store foods and beverages. But in recent years more people have been asking whether exposing our food (and ourselves) to all of this plastic is safe.
Studies have found that certain chemicals in plastic can leach out of the plastic and into the food and beverages we eat. Some of these chemicals have been linked to health problems such as metabolic disorders (including obesity) and reduced fertility. This leaching can occur even faster and to a greater degree when plastic is exposed to heat. This means you might be getting an even higher dose of potentially harmful chemicals simply by microwaving your leftovers in a plastic container.
