While sauna use is not a replacement for exercise or a healthy diet, it can support weight loss in a few meaningful ways. The heat increases your heart rate and metabolic rate, similar to physical activity, which can help your body burn more calories during and shortly after a sauna session. A study published in Complementary Therapies in Medicine (2019) showed that repeated sauna sessions can lead to modest reductions in body fat. Regular sauna use also promotes sweating, which temporarily reduces water weight and helps eliminate excess sodium and toxins that can contribute to bloating, giving you a leaner appearance. For physically active people, saunas aid in recovery, which can help maintain a consistent workout routine, which is crucial for long-term weight management. Additionally, the relaxation and stress-reducing effects of a sauna can help lower cortisol levels, which is important since elevated cortisol levels are linked to increased abdominal fat and weight gain. Sauna use can be a helpful tool for weight loss when combined with diet, exercise, and a balanced lifestyle.
