An analysis of research suggests those who run regularly –– regardless of pace, distance, or amount of time –– are more likely to live longer and have a lower risk of cardiovascular disease or cancer.

Try these simple tips to spice up your workout and keep moving.

Exercise is crucial to good health, but sometimes it's hard to find the motivation to maintain an exercise regimen. Finding the time is one problem. Another is boredom. "Most activity becomes tedious psychologically, even though you know it will benefit you physically," says Michael Bento, a personal trainer at Harvard-affiliated Massachusetts General Hospital.

The solution is finding ways to bust that boredom and stay engaged — or at least distracted.

Not a big fan of running? Good news: You don't need to run fast or far to reap its many rewards.

Running is perhaps the oldest form of exercise and one that offers some of the greatest health benefits.

Running has shown to improve heart health, assist with weight loss, and improve mood. Worried about your joints? Some studies have found that running may actually improve the health of aging knees and ease symptoms of osteoarthritis like joint pain and stiffness.

People with heart disease also have a higher risk of developing cancer, according to research presented at the American Heart Association's Scientific Sessions in November 2019.

Researchers evaluated data from 12,712 people from the Framingham Heart Study who did not have heart disease or cancer at the study's launch. They used a risk estimator that predicts a person's chance for getting heart disease within 10 years.

An increasing body of research shows that dog ownership may boost heart health.

Looking to improve your heart health? You might want to think about getting a dog.

A growing body of scientific research suggests that having a canine companion is associated with number of health benefits, including improved cardiovascular health. "Numerous studies from Scandinavia, England and the United States suggest that dog owners have better health than individuals who don't own dogs. But what we really want to know is whether owning dogs produces better health or if it just means that healthier individuals are more likely to own dogs," says Dr. Dhruv Satish Kazi, a cardiologist and associate director of the Smith Center of Outcomes Research at Beth Israel Deaconess Medical Center and a member of the faculty of medicine at Harvard Medical School.

Q. I've heard a lot recently about inflammation being a health risk, but I'm not sure I really understand what it is. Can you explain?

A. When people talk about inflammation, they're actually talking about your immune system's response to a perceived injury or infection. When you're injured, this inflammation is actually a good thing. The area you injured will become red and swell as an army of beneficial white blood cells flow in to fight infection and help you heal. The same response occurs in other parts of your body when you encounter a virus or infection. But sometimes this immune response occurs when it shouldn't. It can be triggered, for example, when you are exposed to toxins, and by other causes such as chronic stress, obesity, and autoimmune disorders. In these cases, instead of moving in, healing the problem, and then returning to normal, the inflammation persists over time. It's thought that this chronic state of inflammation can lead to numerous health problems, including heart disease, arthritis, depression, Alzheimer's disease, and even cancer.

To help stave off cardiovascular disease, you may not need to run very far, very fast—or even very frequently.

Jogging and running rank among the most popular forms of exercise in this country. But how fast and how long do you need to run to reap the cardiovascular rewards of this activity? A recent study suggests that for both questions, the answer may be less than you think (see "The latest research on jogging and running").

"The main takeaway message is that running even just once a week seems to offer some cardiovascular benefits," says Dr. Adam Tenforde, director of the Running Medicine Program at Harvard-affiliated Spaulding Rehabilitation Hospital. It's heartening news for people who enjoy running but can't do it more frequently, either for logistical reasons or health issues such as knee arthritis, he adds. These findings might also inspire people who do brisk walking to add a few minutes of running to their exercise regimen.

Following five healthy lifestyle habits has been shown to extend life expectancy. Better still, a recent study suggests the added years are more likely to be free of illness or disease.
