Sauna therapy may ease pain and stiffness in rheumatic diseases

Introduction

Rheumatic diseases cause chronic pain and stiffness. This review looked at whether sauna therapy can help reduce symptoms and improve quality of life.

What the study did

Researchers reviewed existing studies on sauna therapy in people with rheumatic diseases like rheumatoid arthritis, ankylosing spondylitis, and osteoarthritis. They examined how heat affects inflammation, pain, and mobility.

What it found

• Sauna therapy may reduce pain and stiffness in people with rheumatoid arthritis, ankylosing spondylitis, and osteoarthritis.
• It may lower inflammatory markers like TNF-α and C-reactive protein.
• It may improve physical function and mobility.
• Regular sauna use may also benefit heart health, which is important for people with rheumatic diseases.

How much to trust it

This is a moderate-trust review of observational human studies. It shows associations, not proof of cause. The biggest limitation is that it summarizes other studies, so the quality depends on the original research.

Your action plan

• If you have a rheumatic disease, talk to your doctor before trying sauna therapy.
• Start with short sessions (5–10 minutes) at a comfortable temperature.
• Stay hydrated before and after sauna use.
• Listen to your body — stop if you feel dizzy or uncomfortable.
