Culinary salts such as Himalayan pink salt, kosher salt, fleur de sel, and flaky sea salt can lend a delightful crunch or flavor to foods. However, they consist largely of sodium chloride, just like table salt, and are no healthier. Consuming too much sodium is tied to increased risks for damage to the heart, kidneys, and brain. Dietitians advise using only a small pinch of a fancy salt, perhaps as a garnish or condiment, to satisfy taste buds without going overboard with the salt shaker.

A 2025 study identified poor sleep along with high blood pressure, nicotine use, and high blood sugar levels as particularly important factors increasing the long-term risk of heart problems for women in midlife.

A 2025 study suggested that women with diabetes are nearly twice as likely as men to have hidden heart disease. These women might especially benefit from early screening for problems in the small blood vessels of the heart.

A 2025 study finds that smoking and high blood pressure are the two most important factors driving heart disease risk. Together with high cholesterol, excess weight (or being underweight), and diabetes, these five factors account for about 50% of the burden of cardiovascular disease. Compared to people with all five risk factors at age 50, those who had none of the factors were far less likely to develop cardiovascular disease or die early. On average, women with none of the risks at midlife lived 13 more years without heart disease, while men lived an additional 11 years.

Heart rate variability (HRV) is a measure of the tiny fluctuations in timing from one heartbeat to the next. Higher values are linked to better fitness levels and stress resilience.

A 2025 study suggests that higher fitness levels may help protect people from developing atrial fibrillation.

Exercise is one of the most powerful tools for preventing heart disease and extending life. Physical activity triggers favorable changes such as making cells more sensitive to insulin and reducing inflammation. It also helps keep blood vessels supple and flexible (which supports efficient blood flow), strengthens muscles (which helps burn more calories), and remodels the heart, making it more efficient at pumping blood through the body. Together, these changes all reduce a person's chances of developing common risk factors for heart disease, including diabetes, high blood pressure, high cholesterol, and obesity.

A free online tool that estimates your heart's age suggests that most adults have a heart that is older than their chronological age, according to a 2025 study.

A 2025 analysis of randomized trials found that cardiac rehab-a personalized program of supervised exercise and healthy lifestyle coaching-can also help people with atrial fibrillation, an irregular heartbeat that can cause stroke and heart failure.
