Listening to music may offer a range of benefits for cardiovascular health.

Music's capacity to evoke emotion is one reason people love listening to it so much. Whether you want to feel energized and uplifted or calm and relaxed, you can probably conjure a few examples of melodies that put you in your desired frame of mind. As it turns out, those mood-related benefits may extend to your heart.

"The beating of your heart and your fight-or-flight system are regulated by your brain. Once you understand that, it makes sense that listening to music that evokes a certain mood might affect the heart's function," says Dr. Andrew Budson, a lecturer in neurology at Harvard Medical School and chief of cognitive and behavioral neurology at the VA Boston Healthcare System.

If you're looking forward to having some extra downtime after retirement, just make sure it doesn't bring more sitting-down time. A study published online Nov. 17, 2020, by the journal Occupational and Environmental Medicine found that on average, women saw a sharp increase in sedentary time — more than an additional 20 minutes each day — after they retired compared with when they were working. This is an unhealthy pattern that can lead to a higher risk for cardiovascular disease.

Researchers identified this trend by looking at data on nearly 700 people (nearly 85% of them women) from a Finnish study. Most of the participants worked in administrative roles or held professional positions before retiring at an average age of 63. To provide objective measurements of activity, the participants wore activity monitors continuously for a full week during their one or two years both before and after retirement. The spike in sedentary time occurred after retirement, and remained at the reduced level for the next two years or more following retirement. Men, by contrast, saw a gradual decline in their activity level over time, but no sudden spike after they left their jobs. So, if you're retiring in the near future, it may be worth keeping an eye on your activity level to make sure you don't slow down after you leave your job.

The soothing and motivational sounds of music have far-reaching health benefits.

A favorite musical tune can stir up positive memories, boost your mood, and create a soothing, relaxing setting. But used in specific ways, music also is a valuable tool for supporting your health.

"Whether you need to relax, increase your energy, improve your thinking, or just get motivated for the day, music can provide extra support when you need it the most," says Marisabelle Diaz-Falcon, a music therapist with Harvard-affiliated Massachusetts General Hospital.

Couples who live together tend to have similar health habits. But only about one in five couples falls into the "ideal" category for heart-healthy habits and risk factors, suggests a study in the Oct. 26, 2020, issue of JAMA Network Open.

Researchers looked at health data on 5,365 couples from diverse racial and economic backgrounds throughout the United States. Most were in their 40s and 50s. Based on risk factors from the American Heart Association's Life's Simple 7 (smoking status, body mass index, exercise, diet, total cholesterol, blood pressure, and fasting blood sugar), researchers categorized individuals and couples as poor, intermediate, or ideal for each factor and over all.

Flexibility helps you stay active and injury-free — and you don't need to do much to see and feel the benefits.

Flexibility is like the famous joke about the weather often attributed to Mark Twain: "Everyone talks about it, but no one ever does anything about it."

People understand the importance of good flexibility as they age. Flexibility keeps them active and helps them safely perform everyday movements.

Doing vigorous exercise for just 12 minutes triggers changes in blood levels of substances linked to cardiovascular health, new research finds.

The study used data from 411 middle-aged adults from the Framingham Heart Study. Researchers measured levels of 588 substances involved in metabolism (metabolites) in the volunteers' blood before and immediately after 12 minutes of vigorous exercise on an exercise bike.

Many people shun wearing face masks when exercising outside or in enclosed gyms because they feel uncomfortable. But another concern is that masks make breathing more difficult, and that rebreathing the higher amounts of carbon dioxide a person exhales when exercising could lead to higher levels of carbon dioxide in the blood.

However, a study published online Nov. 3, 2020, by the International Journal of Environmental Research and Public Health did not find evidence to support either of these worries. Researchers asked healthy, active people to perform cycling exercises until exhaustion on three occasions. For each workout, the exercisers wore either a surgical mask, a cloth mask, or no mask. The researchers found no significant changes in oxygen intake or carbon dioxide blood levels whether the exercisers did or did not wear a face mask. Masks also did not increase heart rates or hasten fatigue.

Your partner's flawed health behaviors may be harming your heart.

It's been said that the longer couples stay together the more they look alike. As it turns out, the resemblance may be more than skin-deep. A study published online Oct. 26, 2020, by JAMA Network Open found that couples' health behavior and heart disease risk factors also look alike — for better or worse.

"We know, even from personal experience, that couples share similar behaviors that can affect health, but it was surprising to find the high levels of shared unhealthy behaviors within couples," says the study's lead author, Dov Shiffman, a senior scientific fellow at the medical testing company Quest Diagnostics.

Here's how to determine which is best for your needs.

Tai chi and yoga have many similarities. Both are gentle, low-intensity exercises that have been practiced for hundreds of years. Both are good for your mind and body (see "Tai chi and yoga benefits"). And both have been shown to be beneficial for older adults in particular. How do you choose one over the other? Several differences can influence your choice.

Strengthening your core using plank exercises can help ease back pain. The plank position is essentially the high part of a push-up. People who can't hold this position can try a modified version by bending their knees and resting them on the ground. Build strength by practicing holding a plank for as long as you can, and then progressively working to hold it for longer each time.
