Saunas at Home: What the Research Says—and What It Doesn’t
A home sauna can offer a dedicated place to pause and unwind. But when shopping for one, it helps to separate the experience you want from health claims that research has not firmly established.

Traditional and infrared: two ways to create warmth
Traditional saunas heat the surrounding air, which warms your body. Infrared saunas use radiant energy to warm the body more directly and generally operate at lower air temperatures. Mayo Clinic explains that both can produce sweating and an increased heart rate. A lower operating temperature does not, by itself, prove that one approach delivers better health outcomes.

Promising research is not a guaranteed result
A 2018 systematic review examined human studies of repeated dry sauna use. It reported potentially beneficial findings but highlighted limitations, including small studies, varied methods and limited randomized evidence. The authors called for further research to establish suitable session frequency and duration for specific outcomes. That means there is no single research-backed routine that can be promised to work for every home user. Read Hussain and Cohen’s systematic review.
Mayo Clinic similarly notes that larger, more rigorous studies are needed to establish the health effects suggested by existing research. Some evidence discussed in relation to infrared saunas actually comes from traditional sauna studies. Findings should not automatically be transferred between sauna types—or to a particular retail model. Source: Mayo Clinic.
Keep the goal realistic
Cleveland Clinic describes relaxation as a reason people enjoy sauna use, while noting that more research is needed on several proposed benefits. It also cautions that a sauna session does not replace exercise. An enjoyable wind-down routine is a more realistic starting point than a promise to prevent illness or transform your health.

Safety comes before a longer session
- Follow your sauna’s instructions and begin with short, comfortable sessions.
- Stay hydrated and avoid alcohol when using a sauna.
- Leave immediately if you feel dizzy or nauseated.
- Seek medical advice before starting if you have a health condition; pregnancy and heat sensitivity require particular caution.
These precautions reflect Cleveland Clinic’s safety guidance. They are not a personalized temperature or session prescription.
Choose for your home, not for a health promise
Before buying, compare the exact model’s dimensions, capacity, electrical requirements, installation instructions and included equipment. General sauna research does not establish that a specific product treats a condition, and the sources cited here do not endorse our store or products.
