For centuries, traditional Finnish saunas have been celebrated for their powerful health benefits — from improving cardiovascular health to reducing stress and supporting better sleep. Unlike infrared saunas, which only appeared in the 1960s and remain less studied, traditional saunas are backed by decades of peer-reviewed research.
At Nosta Sauna Lounge in Mission Viejo, California, we believe in keeping sauna authentic, natural, and science-based. Here are five proven reasons why traditional sauna bathing stands above the rest.
1. Cardiovascular Benefits of Traditional Sauna
Few lifestyle habits are linked to heart health as strongly as sauna use. In a 20-year study from the University of Eastern Finland, people who used a traditional sauna 4–7 times per week had a 63% lower risk of sudden cardiac death and nearly 50% lower risk of cardiovascular disease compared to those who used it once a week (Laukkanen et al., JAMA Internal Medicine).
Infrared saunas often borrow these findings in their marketing, but it’s important to note: the participants were all using Finnish-style stone-heated saunas — not infrared.
2. Stress Reduction & Mental Wellbeing
Traditional saunas are more than just physical therapy — they’re mental therapy, too. A study published in Psychosomatic Medicine found sauna bathing reduced cortisol levels, promoted endorphin release, and eased symptoms of anxiety and depression (Psychosomatic Medicine Journal).
Beyond the science, the ritual itself matters. The cycle of heat, cool down, and repeat mimics mindfulness, grounding the body in the moment. Infrared warms the body — but it doesn’t recreate the same immersive, calming atmosphere of a traditional sauna.
3. Pain Relief & Muscle Recovery
Athletes and chronic pain patients have long leaned on traditional saunas — and the research backs them up. A randomized trial in the Journal of Clinical Rheumatology found that traditional saunas were more effective than infrared saunas in reducing pain and improving function in people with rheumatoid arthritis (Journal of Clinical Rheumatology, 2012).
Heat increases circulation, loosens stiff joints, and helps muscles flush out lactic acid. And unlike infrared, traditional saunas allow for true contrast therapy (alternating hot and cold), which further reduces inflammation and speeds recovery.
4. Detoxification Through Deep Sweat
Sweating isn’t just cooling — it’s cleansing. Traditional saunas raise your core temperature enough to trigger a deep sweat, which supports the body’s natural detox pathways.
A study in the Journal of Environmental and Public Health found that sauna bathing promoted the excretion of heavy metals like mercury, cadmium, and lead through sweat — and traditional saunas were particularly effective due to their higher ambient heat (Journal of Environmental and Public Health, 2012).
Infrared units often operate at lower temperatures (120–140°F versus 170–195°F in traditional saunas), which may limit the depth of sweat and detoxification.
5. Better Sleep & Restorative Relaxation
Ask anyone who’s left a sauna at night: the post-sauna sleep is unmatched. Research confirms this, too. Sauna bathing helps release melatonin, lowers nighttime cortisol, and encourages deeper stages of sleep (PMC Review on Sauna Bathing, 2018).
The gentle rise and fall of body temperature after a sauna mirrors the body’s natural circadian rhythm, making it easier to fall asleep — and stay asleep.
Why Traditional Saunas Are Superior
When it comes to sauna research, the evidence overwhelmingly supports traditional Finnish saunas. Nearly every large-scale, long-term study demonstrating cardiovascular, mental health, and longevity benefits was conducted on traditional stone-heated saunas — not infrared.
By contrast, infrared saunas are far less studied. Many of their claims borrow directly from Finnish sauna research, even though the technology and heat exposure are completely different. Independent reviews, including one from Western Sydney University, have concluded that infrared saunas provide no unique health benefits beyond what traditional saunas already deliver (Western Sydney University Review).
There’s also growing concern about electromagnetic field (EMF) exposure inside infrared cabins. Unlike traditional saunas, which rely on natural heat and steam, infrared units use electrical panels that emit EMFs directly against the body. While research is still developing, some studies suggest prolonged EMF exposure may carry risks — especially for sensitive individuals.
Traditional saunas, by design, do not carry this concern. Their heat is created in the most natural way possible: stones warmed by an electric or wood-fired heater, with steam added as desired.
For those who want the deep, proven, and safest benefits, the evidence points to traditional sauna bathing.
Our saunas hold over 210 lbs of stones, heated the Finnish way. The heat is soft, even, and real — whether you prefer traditional intensity or a gentler session.
It isn’t about chasing trends. It’s about slowing down, breathing deeply, and finding the kind of reset that lasts beyond the session.

Frequently Asked Questions
Q: Is a traditional sauna better than an infrared sauna?
A: Yes. Decades of research show traditional Finnish saunas improve heart health, reduce stress, aid recovery, and promote better sleep. Infrared saunas are less studied and may carry EMF concerns.
Q: How often should I use a sauna?
A: Studies suggest 3–7 times per week provides the strongest cardiovascular and longevity benefits.
Q: Can sauna use help with detox?
A: Yes. Traditional saunas trigger deep sweating that supports the body’s natural detox process, helping eliminate heavy metals and environmental toxins.
Q: Where can I try a traditional sauna in Mission Viejo?
A: At Nosta Sauna Lounge, we offer authentic Finnish-style saunas designed for both traditional and gentle sessions, right here in Mission Viejo, California.
