Are hot flashes a warning sign?

Menopausal hot flashes and night sweats, called vasomotor symptoms, are linked in research to higher odds of dementia and cardiovascular disease. But studies don't necessarily account for other health and lifestyle factors that influence brain and heart health. Women who are physically active and have a lower body mass index are less likely to become cognitively impaired. Disrupted sleep, which is common for women with vasomotor symptoms, may also contribute to cardiovascular and cognitive problems.

Smarter, safer workouts with a wearable fitness tracker

Wearable fitness trackers like smart watches offer measurable and motivating data for exercise routines and safety, especially for people with heart conditions. Features include movement reminders, step counts (a daily total of 4,000 to 7,000 steps is considered beneficial), heart rate zones for exercise intensity, and measurements of heart rate recovery and variability to assess overall heart health. These tools can help optimize workouts and reveal potential issues.

Walking pace linked to reduced risks for an irregular heartbeat

In a 2025 study of more than 420,000 participants followed for about 13 years, people who walked at a steady or brisk pace had up to a 43% lower risk for developing heart arrhythmias, compared with those who walked at a slow pace.

Extreme heat endangers older adults: What to know and do

The surge in heat waves and extreme heat poses serious health risks for everyone but is a particular worry for older adults. What can you do to manage heat-related risks, especially if you have existing health conditions or take certain medications?

Heart-healthy dinner ideas from Harvard doctors

A healthy diet is a proven and powerful way to lower your risk of heart disease. Since dinner is often the main meal of the day, it's a good time to feature foods that support cardiovascular health. Four Harvard physicians share their favorite healthy dinners, which focus on lean protein (such as tofu, fish, and chicken) and a variety of vegetables.

Cannabis and heart concerns: A closer look

Cannabis use is rising among older adults, who mostly use cannabis edibles such as gummies for relaxation and sleep. While smoking cannabis may raise heart attack risk, the cardiac effects of consuming cannabis in food or drinks are less well understood. Taking too much cannabis can lead to a panic attack, which can cause a pounding heart or palpitations. People who use cannabis should take it only as needed to relieve symptoms, using the lowest possible dose.

More than a stretch: How yoga can enhance heart health

A regular yoga practice may help people shed pounds while also improving their heart health. A form of low- to moderate-intensity aerobic exercise, yoga also stretches and strengthens muscles. A 2025 review article suggests that yoga can decrease body mass index, waist circumference, and body fat percentage while also improving blood pressure and cholesterol values.

Midlife pressure surge

High blood pressure means that blood pushes against artery walls more forcefully than normal. Women's blood pressure is typically lower than men's until around age 60. An estimated 41% of women develop high blood pressure after menopause. High blood pressure increases people's risks of heart attack, stroke, kidney disease, and other problems. Factors that increase women's risk of high blood pressure at midlife include menopause, elevated sympathetic nerve activity, weight gain and redistribution, stress, and genetics.

Pill form of popular weight-loss drug lowers heart risks

A 2025 study found that a pill version of the drug semaglutide, marketed as Rybelsus, can lower the risk for serious heart problems in people who have diabetes as well as cardiovascular disease, kidney disease, or both.

Peripheral artery disease: An update

Fatty plaque that accumulates in the arteries of the legs, known as peripheral artery disease (PAD), can cause a painful, crampy sensation in the legs during walking. Smoking, obesity, diabetes, high blood pressure, and elevated cholesterol increase the risk of PAD, which affects nearly one in three people over age 75. Beyond quitting smoking, regular walking is the best treatment for PAD. A 2025 study found that semaglutide (Ozempic, Wegovy) may help people with PAD walk farther with less pain.
