These popular pets have been linked to a range of heart-related benefits.

Seeing a dog's wagging tail and furry face can be heartwarming. But living with and caring for a dog may be heart-protecting — and might even help you live longer, according to a growing body of research.

The latest findings include two articles published last year in Circulation: Cardiovascular Quality and Outcomes. One pooled findings from 10 studies involving a total of 3.8 million people who were followed between one and 22 years. Dog owners were 31% less likely to die from a heart attack, stroke, or other cardiovascular condition than people who didn't own dogs. A separate study, which followed more than 335,000 heart attack and stroke survivors over 12 years, found that having a dog was linked to a 21% lower risk of death from any cause.

This low-impact, lifelong sport can be a good way to exercise, socialize, and enjoy nature — three factors linked to lower heart disease risk.

Famously described as "a good walk spoiled," golf is nonetheless a popular sport in the United States, played by an estimated 25 million Americans. And one could argue that rather than spoiling a nice walk, the game instead provides a good way for people of all ages to be physically active and reap other heart-related rewards.

"You're outdoors in a beautiful place with three friends and no phones or computer screens," says Dr. James Muller, a cardiologist at Harvard-affiliated Brigham and Women's Hospital. In today's world, people are often stuck behind their screens and lose touch with their in-person social community. Playing golf helps to remedy that problem.

Q. I have pelvic organ prolapse and I want to start working out. Are there exercises I should avoid?

A. Pelvic organ prolapse is a common problem, caused by a weakening of the bowl-shaped group of muscles and tissues that supports your pelvic organs. As this support fails, one or more of these organs — such as the uterus, bladder, or rectum — can shift out of place, typically pushing into (and sometimes protruding out of) the vagina.

When you were a child and your mother told you to go play outside, it wasn’t just because she needed some child-free time. Inspired by a Japanese practice, forest therapy is an immersion in nature that has been shown to have positive effects on health.

People are often surprised to learn that there's more to walking than simply putting one foot in front of the other. In fact, a little technique goes a long way to making your walks more enjoyable and more effective. Technique is especially important if you are hoping to become fitter and lose weight, because it will enable you to walk faster and longer. When you're standing tall, your muscles will move through a greater range of motion for a more powerful stride. Improving your walking posture will help you to look and feel more confident, too—and you'll look slimmer before losing a single pound. It will also help alleviate aches and pains and allow you to take deep breaths for more energy.

For any type of walking

Here's what the numbers mean — and strategies to lower your cholesterol if it's too high.

For some women who've had normal cholesterol readings all their lives, that changes at menopause. "Going through menopause often results in lipid and cholesterol changes for the worse," says Dr. Samia Mora, an associate professor of medicine at Harvard Medical School and a specialist in cardiovascular medicine the Brigham and Women's Hospital. Drops in the female hormone, estrogen, are associated with a rise in total cholesterol levels due to higher amounts of low-density lipoprotein (LDL), the "bad" cholesterol, and another blood lipid (fat) known as triglyceride. Over time this can raise heart risks, which is a reason for concern, as cardiovascular disease is the No. 1 cause of death in postmenopausal women, says Dr. Mora.

"So, it's especially important to track the numbers in perimenopause and the early years after menopause, as LDL cholesterol and total cholesterol tend to increase," she says.

Some trends are high-tech, and some go back to basics.

One of the best ways to sustain an exercise regimen is to find an activity that appeals to you. And four new exercise trends may pique your interest. They're not age-specific and most can be tailored to your needs. But they do have pros and cons.

1. Circuit training

When people talk about circuit training in 2020, they're probably not referring to working out on a series of weight machines. Today's circuit consists of a series of exercises, set up at separate "stations" in various parts of a large exercise room. "The exercises focus on agility, balance, or strength, and they alternate between upper- and lower-body movements to avoid excessive fatigue in any one muscle group," says Michael Bento, a personal trainer at Harvard-affiliated Massachusetts General Hospital.
