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.

Wildfire smoke contributes greatly to poor air quality, and as wildfires become more frequent due to climate change and drier conditions, more of us and more of our communities are at risk for health harms. Here are ways to cope.

A 2025 study found that a new type of medication may safely slow the progression of aortic stenosis (narrowing of the aortic valve) and delay the need for valve replacement.

When blood pressure remains high despite treatment, making certain lifestyle changes can help. Examples include reducing dietary sodium and increasing dietary potassium, losing weight, limiting alcohol intake to no more than one drink per day, exercising (doing aerobics and strength training), using tools that improve medication adherence (such as an automatic pill dispenser, a medication diary, a smartphone alarm, or a reminder app), quitting smoking, getting more sleep, managing stress, and reducing caffeine intake.

The purported health benefits of cold plunges include less stress, better sleep, and enhanced immunity, but the evidence is thin. While the practice may ease muscle soreness after intense exercise, it may have detrimental effects on gains in muscle power and strength. Because the shock of cold water on the skin can raise heart rate and blood pressure, people with cardiovascular disease (especially heart rhythm abnormalities) should avoid the practice.

A 2025 study found that people who are sedentary for 10.6 hours per day or more may face a higher risk of heart failure or dying from heart disease-even if they follow recommended exercise guidelines. Uninterrupted sitting has harmful effects on metabolism, leading the body to burn fewer calories and less fat. It can also cause blood sugar levels to rise, triggering the release of insulin, the hormone that regulates blood sugar. Over time, sedentary habits cause the body to become less sensitive to insulin. The resulting insulin resistance promotes inflammation, a key player in the buildup of fatty plaque inside arteries.

Trading about a tablespoon of butter per day for about two teaspoons of olive, soybean, or canola oil may help lower the risk of heart disease and premature death, according to a 2025 study.
