Sauna for Arthritis in Australia: What the Evidence Shows
Key Takeaways
- Just under 3.7 million Australians (14.5%) had arthritis in 2022, according to the Australian Bureau of Statistics.
- On sauna for arthritis, small studies suggest heat may ease pain and stiffness in the short term: a pilot study of infrared sauna in people with rheumatoid arthritis and ankylosing spondylitis reported short-term improvements and good tolerance (Oosterveld et al., Clinical Rheumatology, 2009). The evidence is limited.
- In a 20-year Finnish study of 2,315 men, sauna use 4–7 times per week was associated with about a 50% lower risk of fatal cardiovascular disease (Laukkanen et al., JAMA Internal Medicine, 2015). That is relevant context, because people with inflammatory arthritis tend to have higher cardiovascular risk, but it is an association, not proof.
- Clean materials matter: some cheaper saunas use glued panels or MDF that can release volatile organic compounds such as formaldehyde when heated. The Genesis uses no glue, no MDF and no wood filler.
- A home sauna makes regular, comfortable sessions easier, which is what most people with arthritis need to judge whether heat helps them.
- Contrast therapy (alternating heat and cold) has some evidence for exercise recovery, but it has not been studied in arthritis, and cold can increase stiffness in some people.
- People on immunosuppressants or other arthritis medicines, those in an active flare, and anyone with heart disease or uncontrolled blood pressure should speak to their rheumatologist or GP before starting sauna use.

Can a sauna help arthritis? For many Australians with osteoarthritis or rheumatoid arthritis, warmth eases stiffness, and small studies suggest sauna may bring short-term relief from pain and stiffness. A 2018 review of sauna research noted possible symptom improvement in arthritis (Laukkanen et al., Mayo Clinic Proceedings, 2018), and a systematic review of dry sauna studies concluded there are potential health benefits but that better-quality trials are needed (Hussain and Cohen, 2018). Sauna for arthritis is a complement to medical care, not a treatment.
Heat relaxes tight muscles around stiff joints, increases blood flow to the skin and can make movement feel easier. It may also dampen pain signals for a while. These are plausible reasons people feel better, but they have not been measured precisely in sauna studies of arthritis.

SEE THE GENESIS →Nearly 3.7 Million Australians Live With Arthritis
Arthritis is not a minor inconvenience. According to the Australian Bureau of Statistics, just under 3.7 million Australians (14.5%) had arthritis in 2022. It is a major cause of chronic pain and reduced mobility.
Management usually combines medicines, physiotherapy, exercise, weight management and simple measures such as heat packs, guided by a GP or rheumatologist.
A sauna warms the whole body rather than one joint, which is why some people find it more helpful than a heat pack. Whether that translates into lasting benefit has not been well studied.
If you are managing arthritis and are curious about sauna, it is worth discussing with your doctor as one complementary option. For a broader view of the research on heat therapy, our guide to sauna benefits in Australia covers the wider picture.
What Heat Actually Does to Arthritic Joints: The Science
Several mechanisms have been proposed for why heat helps people with arthritis feel better. Some are well understood; others are still hypotheses.
Warmth, Stiffness and Movement
Synovial fluid lubricates your joints. Many people with arthritis notice that their joints feel stiffer in the cold and looser when warm.
How much a sauna changes the joints themselves has not been measured in sauna studies, so treat this as a plausible explanation for how warmth feels rather than a proven effect.
Inflammation
In a cross-sectional analysis of Finnish men, more frequent sauna use was associated with lower levels of C-reactive protein (CRP), a marker of inflammation (Laukkanen et al., European Journal of Epidemiology, 2018). That shows an association at one point in time, not that sauna lowers inflammation. A small Japanese study of repeated thermal (Waon) therapy in people with chronic pain reported improvements in pain (Masuda et al., Psychotherapy and Psychosomatics, 2005).
Sauna does not replace disease-modifying antirheumatic drugs (DMARDs) or other prescribed treatment. If you have inflammatory arthritis, talk to your rheumatologist before starting.
Muscle Relaxation and Pain Gate Modulation
Heat helps relax the muscles around stiff joints, which can make movement more comfortable. Warmth also activates temperature receptors in the skin, which may temporarily dull pain signals.
Many people say the relief lasts a while after the session, although this has not been measured in controlled studies of traditional sauna.
The cardiovascular connection may matter for people with arthritis. In a 20-year Finnish study of 2,315 men, those who used a sauna 4–7 times per week had about a 50% lower risk of fatal cardiovascular disease than once-weekly users (Laukkanen et al., JAMA Internal Medicine, 2015). People with inflammatory conditions such as rheumatoid arthritis tend to have higher cardiovascular risk, so this is relevant context, but it is an association in men without arthritis data, not proof that sauna protects the heart. Our guide to sauna and cardiovascular health in Australia explores this evidence in full.
Traditional Finnish Sauna vs Infrared for Arthritis
Much of the arthritis-specific sauna research has actually used infrared or mild thermal (Waon) therapy, not traditional Finnish saunas. The Oosterveld pilot study, for example, used an infrared sauna.
Infrared saunas run at about 45–65°C and warm the body mainly by radiant panels. Traditional Finnish saunas run hotter, typically around 70–100°C, and let you pour löyly for steam. Neither has strong evidence for long-term benefit in arthritis, so choose the heat you find comfortable and can use regularly.
The long-term Finnish cohort studies on cardiovascular outcomes involved traditional saunas, and there is no equivalent long-term infrared data. For arthritis symptoms specifically, the small trials available are mostly infrared. For the full comparison, see our guide to traditional vs infrared sauna.
| Factor | Finnish Sauna (Traditional) | Infrared Sauna |
|---|---|---|
| Temperature range | Typically 70–100°C | 45-65°C |
| Core temperature elevation | Larger rise, faster | Smaller rise, depends on session length |
| Arthritis symptom studies | Very limited | Small pilot studies (e.g. Oosterveld et al., 2009) |
| Inflammatory marker reduction | Lower CRP with frequent use in Finnish men (cross-sectional) | Limited data |
| Löyly (steam) capability | Yes, central to the experience | No |
| Long-term outcome research | About 20-year cohort studies on cardiovascular outcomes (Laukkanen et al.) | No equivalent longitudinal data |
| Construction materials (Psycle) | Clear-grade Japanese cedar, no glue, no MDF, no wood filler | Varies by brand |
Why Sauna Materials Matter
Some home saunas sold in Australia use glued panels, MDF or particle board. Many adhesives and engineered boards can release volatile organic compounds such as formaldehyde, which IARC (the WHO’s cancer agency) classifies as a Group 1 carcinogen, and heat generally increases emissions.
Nobody wants to breathe chemical emissions in a hot, enclosed room, whether or not they have arthritis.
That is why construction materials are a health decision as well as an aesthetic one. The Genesis uses clear-grade Japanese cedar with 38mm walls and no glue, no MDF and no wood filler. The Natural finish is untreated; the Charcoal finish uses a non-VOC black paint.
The lighting is amber and red and free of blue light, which is gentler in the evening. Many people with arthritis already have sleep disrupted by pain, so a relaxing evening routine can help.
The Sauna Protocol for Arthritis: What the Evidence Actually Supports
There is no established sauna protocol for arthritis. The routine below is general guidance for adults whose doctor is happy for them to use a sauna.
Preheat fully
Let the sauna reach a comfortable temperature before entering. If heat is new to you, start at the lower end and use the lower bench.
Session duration: start short
Start with 5–10 minutes and build up gradually to around 15–20 minutes if you feel well. Exit if you feel dizzy, nauseous or overly fatigued.
Add löyly if you enjoy it
Pouring a ladle of water over the stones creates steam and makes the room feel hotter. It is optional; use it if you find it comfortable.
Cool down: 10-15 minutes
Step outside or take a cool shower. A gradual cool-down is usually more comfortable than cold exposure for stiff joints. Use the time to move your joints gently through a comfortable range while they are warm.
Hydrate
You can lose a significant amount of fluid through sweat in a sauna. Drink water before and after your session.
Frequency: what suits you
There is no proven frequency for arthritis. In the Finnish cardiovascular research, the lowest risk was seen with 4–7 sessions per week, but that was not an arthritis study. Start with two or three sessions a week and adjust based on how your joints respond.
Is Contrast Therapy Beneficial for Arthritis?
Contrast therapy, alternating hot and cold, is popular for exercise recovery. The question for people with arthritis is whether cold helps or hinders.
The evidence comes from sport, not arthritis. A 2013 meta-analysis of 18 small trials found that contrast water therapy reduced soreness and strength loss after exercise compared with passive recovery, but found little evidence that it beat other methods (Bieuzen et al., PLoS One, 2013). It has not been tested in arthritis.
Cold can temporarily increase joint stiffness, and cold immersion is not suitable for people with Raynaud’s phenomenon or some heart conditions. If you want to try contrast therapy, get medical clearance first. Our contrast therapy guide covers routine, timing and safety.

EXPLORE THE GENESIS →What to Look for in a Home Sauna for Arthritis Management
If you are buying a home sauna with arthritis in mind, a few specifications matter more than they do for other buyers.
Temperature Control
You want a sauna that holds a steady, comfortable temperature, so you can choose a gentler or hotter session. The Genesis uses a 9kW heater: the HUUM DROP carries about 60kg of stones and the Harvia Vega about 20kg. Stone mass helps the room hold its heat when the door opens or you pour löyly.
Clean Construction
Look for glue-free construction without MDF or particle board. The Genesis uses clear-grade Japanese cedar with 38mm walls, no glue, no MDF and no wood filler.
Ventilation
Fresh air makes a session more comfortable. The Genesis runs Psycle Clean Air active ventilation at 88 or 120 m³/h, plus a passive hatch. Our guide to sauna ventilation in Australia explains why it matters.
Size and Accessibility
For people with arthritis, easy entry and comfortable seating matter. The Genesis seats 3–5 people on an L-shaped bench, with an external footprint of 2278mm wide × 2438mm deep. If space is tight, the Genesis Mini seats 1–3 people on the top bench (up to 4 in total) with a 6kW heater and the same materials. The Genesis front is full-face 8mm laminated tempered glass with a hinged door. Check bench and step heights in person or with the team if mobility is limited.
| Specification | Genesis (3-5 person) | Genesis Mini (1-3 person) |
|---|---|---|
| Timber | Clear-grade Japanese cedar, 38mm walls | Clear-grade Japanese cedar |
| Heater options | HUUM DROP 9kW / Harvia Vega 9kW | HUUM DROP 6kW / Harvia Vega 6kW |

| External dimensions | 2342H x 2278W x 2438D mm | 2304H x 1571W x 1946D mm |
| Electrical requirement | Dedicated 240V 50A single-phase or 415V 20A three-phase | Dedicated 32A (single- or three-phase) |
| Warranty | 5-year structural cabin / 3-year HUUM or 2-year Harvia heater | 5-year structural cabin / 3-year HUUM or 2-year Harvia heater |
Safety Considerations: Who Should Exercise Caution
Sauna is generally well tolerated, but not by everyone. The following groups should get medical clearance before starting.
Active inflammatory flare-up: During an acute flare, heat on hot, swollen joints may make things worse. Wait for the flare to settle and check with your doctor before resuming.
Arthritis medicines: DMARDs, biologics, corticosteroids and some pain medicines can affect infection risk, blood pressure or how you tolerate heat. Discuss sauna use with your rheumatologist before starting.
Heart disease or uncontrolled blood pressure: Sauna raises heart rate and changes blood pressure. Get medical clearance first. Our guide to sauna and blood pressure in Australia covers the evidence.
Severe joint damage or recent surgery: If you have had recent joint replacement surgery or have severe structural damage, the heat protocol should be introduced gradually and with clinical supervision.
For a complete review of precautions, our sauna health risks guide is worth reading before you start.
Is a Home Sauna Worth It?
Whether a home sauna is worth it depends on how often you will use it and how much you enjoy it.
A home sauna is a lifestyle purchase, not a medical treatment, and it should not replace physiotherapy, exercise or prescribed care. What it offers is easy access: no travel or bookings, so regular sessions are realistic.
Running costs depend on your electricity tariff, preheat time (typically 45–60 minutes) and session length.
The Genesis is a premium sauna: clear-grade Japanese cedar with no glue, a 9kW heater and a 5-year structural cabin warranty. Our home sauna cost guide covers pricing, installation and running costs.
Frequently asked questions
Is sauna good for arthritis?
It may help some people. Small studies suggest sauna can ease pain and stiffness in the short term, including a pilot study of infrared sauna in rheumatoid arthritis and ankylosing spondylitis (Oosterveld et al., 2009). In Finnish men, frequent sauna use has been associated with lower CRP, an inflammation marker, but that does not prove sauna reduces inflammation. Sauna does not replace medical treatment; speak to your doctor first.
Can you use a sauna during an arthritis flare-up?
During an active flare, heat on hot, swollen joints may make things worse, so it is usually best to wait for it to settle and check with your doctor. If you take immunosuppressant medication (DMARDs, biologics or corticosteroids), get clearance from your rheumatologist before using a sauna. For stable arthritis, many people tolerate sauna well.
How often should you sauna for arthritis?
There is no proven frequency for arthritis. Start with two or three sessions a week and adjust based on how your joints respond. In the Finnish cardiovascular research, the lowest risk was seen with 4–7 sessions a week, but that was not an arthritis study.
Is infrared or traditional sauna better for arthritis?
Neither has strong evidence for arthritis. The small arthritis studies available mostly used infrared or mild thermal therapy, while the long-term Finnish research on heart health used traditional saunas. Choose the heat you find comfortable and can use regularly, and ask your doctor if you are unsure.
What is the best home sauna for arthritis in Australia?
