Can regular sauna sessions support a healthy heart?

Population-based studies have linked regular sauna use with better heart health.

However, randomized trials haven't found much evidence that saunas can improve measures of cardiovascular health. People with low blood pressure, valve disease, and heart failure should be cautious while using saunas.
