In three long-term studies, children of centenarians had lower rates of high blood pressure when compared with others whose parents had shorter life spans. They also tended to have less heart disease, develop health problems later, and live about three years longer.

An analysis of 87 studies found that eating more whole grains may provide modest improvements in cholesterol, triglycerides, blood sugar, weight, blood pressure, and inflammation.

A 2026 study of adults with nonspecific low back pain found that adding a soft, adjustable lower-back support (lumbar belt) to usual care improved disability and pain after 12 weeks and ​was better than usual care alone. People wearing a lumbar belt also used less pain medication.

Sleeping in a dark room may do more than improve sleep; it may also benefit heart health. A 2026 study linked nighttime light exposure with harmful changes in heart structure and higher risks of heart failure, atrial fibrillation, heart attack, stroke, and death from heart disease.
