Home saunas have evolved from niche luxury items to essential wellness tools, backed by scientific research.

A 2025 review in Frontiers in Cardiovascular Medicine highlighted that sauna sessions mimic moderate aerobic exercise, offering benefits for individuals with limited mobility or those complementing their fitness routines. Whether for health or relaxation, the best home saunas make it easy to establish a consistent sweat routine without gym memberships or spa visits. Saunas come in two main types: traditional steam and infrared. Steam saunas heat the air around you, often reaching 150–200°F using heaters or water poured over hot rocks. Infrared saunas, on the other hand, use electromagnetic wavelengths to warm your body directly at lower temperatures (120–165°F). Research from PopSci and independent studies shows infrared heat can reduce blood pressure, improve vascular function, and provide relief for muscle soreness and rheumatoid arthritis symptoms. Some advanced models now include red light therapy and full-spectrum infrared wavelengths, adding layers of wellness benefits. When selecting a sauna, consider factors like heating method, portability, and technology.
