The raised, tortuous vessels may be controlled with support hose, and they can be eradicated in a quick, outpatient procedure.

Varicose veins are one cardiovascular condition that usually isn't considered serious or life-threatening. Around half of all women have them, and most regard them as a cosmetic annoyance. However, they can be responsible for swollen legs, skin changes, and the development of leg ulcers.

Research we're watching

An analysis published online Sept. 17, 2015, by the British Journal of Sports Medicine suggests that doing tai chi enhances the quality of life for people with common chronic conditions.

Researchers analyzed data from 33 studies involving nearly 1,600 adults. Most were in their 60s or 70s, and all had one or more chronic conditions: osteoarthritis, breast cancer, heart failure, or chronic obstructive pulmonary disease (COPD). All 290 participants in the breast cancer studies were women. There were 452 women (85% of participants) in the arthritis studies, 76 (16%) in the heart failure studies, and 92 (19%) in the COPD studies.

Almost everyone suffers from trouble sleeping at one time or another. Insomnia — defined as trouble falling asleep or staying asleep — isn't a single disorder itself, but rather a general symptom, like fever or pain.

Because insomnia is so common, you can walk into any drugstore and find a bewildering variety of over-the-counter sleep products. And people are buying them. One small survey of people ages 60 and over found that more than a quarter had taken nonprescription sleeping aids in the preceding year — and that one in 12 did so daily.

Q. I've been drinking Fresca since I was in college. Lately I've been reading that diet drinks may cause weight gain and have other bad effects. Is that true?

A. There is some controversy about whether drinking diet soda helps or hurts in maintaining or achieving a healthy weight. Some studies show that people who consume artificially sweetened drinks take in fewer calories and are better able to control their weight. However, other studies show the opposite—that consuming diet drinks may result in weight gain as well as type 2 diabetes.

Beer, wine, and spirits are foods as well as intoxicants that have different effects in women than in men.

In the first episode of the sitcom "Grace and Frankie," the title characters, played by Jane Fonda and Lily Tomlin, are ordering drinks before dinner. When carb-conscious Fonda sends the breadbasket away and asks for a very dry vodka martini, Tomlin reminds her that vodka is made from potatoes. Fonda responds, "Alcohol has its own rules."

New evidence indicates that more frequent and more vigorous activity can turn back the biological clock.

Fifteen minutes of vigorous exercise or 30 minutes of moderate activity several times a week can reduce your risk of cardiovascular disease, obesity, diabetes, cancer, depression, and dementia. But according to recent studies, exercising even more vigorously for longer periods may have additional benefits by taking years off your biological age. It does so by increasing aerobic capacity—the amount of oxygen you can take in and distribute to your tissues in a minute. "Some studies have indicated that people in their 80s who exercised at high intensity for 20 to 45 minutes a day have an aerobic capacity of people 30 years younger," says Dr. J. Andrew Taylor, director of the cardiovascular research laboratory at Harvard-affiliated Spaulding Rehabilitation Network.

If you're "leaning in" by putting in extra hours on the job, you may be gaining gender equality that you don't want—the same stroke risk as your male colleagues. A recent analysis indicates that women who work 55 hours or more per week have a 30% higher risk of having a stroke than those working standard hours, making them just as likely to have a stroke as their male counterparts.

The analysis, published online Aug. 20, 2015, by The Lancet, was conducted by European public health re-searchers. It involved data from over 600,000 women and men enrolled in long-term observational studies in Europe and the United States. It was the first such analysis of the relationship between working long hours and stroke. The researchers noted several factors that might have contributed to the elevated stroke risk, including the additional stress of balancing the extra work hours, inactivity, long periods of sitting, and ignoring stroke warning signs.

A variety of physical activities and regular stretching can rid you of routine discomfort.

Here's how to enhance the foods you already like with heart-healthy plant sources.

According to a recent national food survey by the CDC, 87% of American adults do not eat the minimum daily recommended portions of fruit (1.5 to 2 cups), and 91% are not getting the recommended amount of vegetables (2 to 3 cups a day). The reasons for this unhealthy trend vary. One important factor is that food preferences, including an aversion to fruits and vegetables, form early in life and can be hard to change. "People say, 'I don't like salad' and 'I don't like spinach,' and that's that," says Stacey Nelson, a registered dietitian and manager of clinical nutrition at Harvard-affiliated Massachusetts General Hospital.
