Scientists in Finland have shown that sauna bathing is associated with a variety of health benefits. The latest study with 100 test subjects shows that taking a sauna bath of 30 minutes reduces blood pressure and increases vascular compliance, while also increasing heart rate similarly to medium-intensity exercise.
Researchers have also published findings indicating that regular sauna bathing is associated with a reduced risk of coronary diseases and sudden cardiac death, hypertension and Alzheimer's disease and dementia. Frequent sauna bathing has also been associated with a reduced risk of respiratory diseases and lower CRP levels.
During sauna bathing, test subjects' heart rate increased similarly to medium-intensity exercise, and their body temperature rose by approximately 2°C giving a considerable boost to immune system strength.
