Are Saunas Good for Arthritis?

Living with arthritis can turn everyday tasks into frustrating challenges. Opening a jar, climbing stairs, or even getting out of bed may feel harder when your joints are stiff and painful.

The good news? Personal saunas can help ease arthritis pain, stiffness, and fatigue, offering meaningful symptom relief even though they won't cure the condition. This guide explores how heat therapy works, what the research shows, and how to safely integrate sauna sessions into your arthritis management routine.

We support every stage of your wellness journey with accessible at-home heat therapy options designed to help you feel better, one warm session at a time.

Understanding Sauna Therapy

You're tapping into centuries of wisdom when you use heat to soothe your aching body, and modern saunas continue that tradition. Are saunas good for arthritis pain? Many people find relief through regular sessions.

Sauna types offer different approaches to heat therapy:

• Traditional (Finnish) saunas: Warm the surrounding air to high temperatures, typically between 150-195°F
• Infrared saunas: Use light panels that warm your body directly at lower, more comfortable temperatures
• Portable sauna blankets: Offer a compact infrared option perfect for home use

When comparing an infrared vs. a traditional sauna, the key difference lies in how heat reaches your tissues. Traditional saunas heat the air around you, while infrared heat penetrates deeper into muscle and joint tissue. Both approaches raise your core body temperature, triggering beneficial responses that can help reduce arthritis symptoms.

How Heat Acts on the Body

When your body temperature rises, you experience several helpful changes:

• Vasodilation: Blood vessels widen, improving blood flow and delivering oxygen-rich nutrients to your joints
• Muscle relaxation: Tight muscles surrounding stiff joints begin to loosen
• Endorphin release: Your body produces natural pain-relieving chemicals that boost mood

Over time, regular sauna use may also help reduce markers of inflammation, such as C-reactive protein. This connection often comes up in conversations if infrared saunas are good for you and their potential long-term wellness benefits.

Potential Benefits for People With Arthritis

Both osteoarthritis and rheumatoid arthritis sufferers may find relief through regular heat therapy sessions. A 2025 review published in Rheumatology International found clinical evidence that sauna therapy alleviates pain, reduces stiffness, and improves mobility in patients with RA, ankylosing spondylitis, and OA.¹

Are infrared saunas good for arthritis? The evidence points to several promising benefits of infrared saunas for joint health.

Pain & Stiffness Reduction

Warmth helps alleviate tight connective tissue while relaxing the muscles that guard painful joints. This combination makes everyday movements feel easier and less uncomfortable.

In a pilot study, Oosterveld and colleagues found promising results when they examined the effects of infrared saunas on people with rheumatoid arthritis and ankylosing spondylitis.² Arthritis patients experienced short-term improvements in pain and stiffness without triggering disease flare-ups.

Mobility & Flexibility Support

Warm muscles and tissues respond much better to gentle stretching and low-impact exercise. Many people report improved joint mobility for several hours after a sauna session.

This post-sauna window creates an ideal opportunity for mobility work. Light stretching during this time can help you gradually expand your comfortable range of motion.

Quality-of-Life Upsides

Beyond physical symptoms, sauna therapy offers mental health benefits worth considering. The calm, warm environment provides a welcome respite from the stress that often accompanies chronic pain.

Regular sauna users frequently report:

• Reduced fatigue throughout the day
• Improved sleep quality at night
• Enhanced overall well-being and stress relief

Evidence Snapshot & Limitations

Let's take an honest look at what science currently supports and where questions remain.

What the Research Says

The 2009 Oosterveld pilot study is among the most frequently cited sources demonstrating that sauna therapy can benefit people with arthritis. Participants with RA and ankylosing spondylitis showed reduced pain and stiffness with no adverse effects reported.

More recently, Fedorchenko's 2025 review explored how infrared sauna therapy may help reduce inflammation and support cardiovascular health. A government-conducted systematic review also documented symptom improvements after dry sauna therapy in patients with rheumatological and immune conditions.³ The review noted that most studies are small with varying methodologies.

While these findings are encouraging, larger trials will help us better understand how saunas support joint health.

What Saunas Don't Do

It's important to set realistic expectations. Saunas cannot:

• Halt cartilage breakdown in affected joints
• Reverse existing joint damage or deformity
• Suppress autoimmune activity in rheumatoid arthritis

Think of heat therapy as a helpful addition to your management plan. Sauna sessions complement medical treatments and other modalities rather than replacing them.

Safety Considerations

When asking if infrared saunas are safe, research suggests this therapy is generally well-tolerated, with the Oosterveld study reporting zero adverse effects among participants.

Smart precautions still matter:

• Drink plenty of water before and after each session to stay properly hydrated
• Start with shorter sessions and gradually increase duration as your body adapts
• Exit the sauna immediately if you feel dizzy, lightheaded, or unwell

One of the most common questions for new sauna users is how hot should a sauna be, especially when trying to balance an effective session with comfort. The ideal temperature often comes down to the type of sauna, individual preference, and how long someone plans to stay in the heat.

Who Should Consult a Physician First

Talk with your doctor before starting sauna therapy if you have:

• Unstable heart disease or uncontrolled blood pressure
• A recent cardiac event in your medical history
• Pregnancy or planning to become pregnant
• Medications that affect fluid balance or heat sensitivity
• Rheumatoid arthritis or other autoimmune disorders

If you have rheumatoid arthritis or another autoimmune condition, discuss any new complementary therapy with your rheumatologist.

When to Skip a Session

Avoid the sauna during these situations:

• Acute inflammatory flare-ups marked by active swelling, redness, or fever
• Feeling unwell, dehydrated, or experiencing illness
• Wearing medicated patches that may be heat-sensitive

An increase in blood flow could lead to an increase in swelling when there is active injury or inflammation, which means heat can worsen inflamed joints during these episodes.⁴ People with RA should monitor their symptoms and adjust accordingly.

Integrating Sauna Into an Arthritis-Friendly Routine

Now let's turn knowledge into action with a practical plan you can follow.

Getting Started

If you are wondering how often you should use an infrared sauna, begin with just a few sessions per week at moderate temperatures. Stanford Lifestyle Medicine recommends starting with 5-minute sessions and gradually increasing to 15 to 20 minutes as your body adapts.⁵

Listen to your body and increase duration only when you feel ready.

Incorporating sauna therapy with gentle stretching immediately afterward can multiply your benefits. It also ties into the common question of whether to sauna before or after workouts, especially for those trying to time heat exposure around exercise in a way that fits their goals.

Tracking Progress

Consider keeping a simple symptom journal where you rate pain, stiffness, and fatigue before and after each session. This habit helps you notice patterns you might otherwise miss.

After several weeks, review your trends and adjust frequency or duration based on what works for you. This personal data also helps you have more productive conversations with healthcare providers about your RA symptoms and routine.

Making the Most of Your Session

Prepare for each session by:

• Hydrating well before stepping in
• Wearing loose, comfortable clothing or wrapping yourself in a towel
• Planning for sweat with appropriate preparation

Many people use their sauna time for mindfulness or deep breathing exercises. A common question some have is can you bring your phone in a sauna, which you shouldn't do given the risk of overheating or device damage. With sauna blankets, however, some may feel more comfortable using a phone if their hands remain outside the heated area.

Choosing the Right Sauna Solution

When choosing among the different types of infrared saunas, consider your living space, budget, and daily routine.

Full-Size Cabin vs. Infrared Blanket

Both options deliver infrared wavelengths effectively to help you feel better. An infrared sauna blanket gives you greater portability without sacrificing the therapeutic value you need.

Key Features to Look For

When shopping for an infrared sauna, prioritize these qualities:

• Even heat distribution across the surface
• Adjustable temperature settings for personalized comfort
• Low-EMF design for peace of mind
• Safety certifications from recognized testing organizations
• Responsive customer support and a strong warranty
