Chronic inflammation doesn’t always announce itself. It lingers quietly in the background, raising your risk of joint pain, fatigue, autoimmune flare-ups, and even heart disease. Unlike the short-term swelling that protects a cut or heals a bruise, low-grade inflammation can persist for years, wearing down the body in ways we are only beginning to understand.
Now, research is pointing to heat and cold therapies as practical tools for managing this hidden threat.
Understanding Inflammation
Inflammation is a protective response. But when it becomes constant, it can lead to or worsen a range of conditions including rheumatoid arthritis, psoriasis, and metabolic syndrome. One of the clearest markers for systemic inflammation is C-reactive protein (CRP), which tends to remain elevated in people with ongoing inflammatory stress.
Other inflammatory molecules, like interleukin-6 (IL-6), also rise when the immune system is under continuous strain. Over time, these changes may damage tissues and lead to chronic pain, fatigue, and reduced resilience.
What the Research Shows
A 2021 review in Temperature found that passive heat exposure through sauna use can significantly lower inflammatory markers like IL-6 and CRP. In another large-scale study published by JAMA Internal Medicine, participants who used saunas four to seven times per week had markedly lower levels of CRP, along with a reduced risk of cardiovascular-related mortality.
Cold exposure also plays a role. Alternating between hot and cold, commonly known as contrast therapy, triggers a process of vasodilation and vasoconstriction that helps reduce inflammation and improve immune surveillance.
A 2022 article on Renutherapy.com explains that this pattern improves circulation to inflamed joints and may reduce swelling associated with autoimmune conditions like rheumatoid arthritis. SaunaHouse.com and WebMD also report that this thermal contrast helps flush out waste products and calms overactive immune responses, making flare-ups less frequent and less intense.
Application to Real Conditions
- Rheumatoid arthritis: Many users report decreased joint pain and stiffness after regular contrast therapy. Improved circulation helps clear inflammatory waste products from the affected areas.
- Psoriasis: Though individual results vary, some studies suggest sauna sessions may help reduce the severity of flare-ups by calming systemic inflammation and improving skin perfusion.
- General inflammatory pain: Regular heat exposure has been shown to improve pain thresholds and reduce sensitivity to chronic discomfort, making it easier to stay active.
Why Routine Is Key
A single session can feel good, but the greatest benefits appear when heat and cold exposure become part of a regular weekly rhythm. This consistency helps regulate the immune system over time, much like steady exercise or sleep habits do.
At Wellness One Lifestyle, our sauna and contrast bath ranges are built with this repeat use in mind. From the quiet performance of our indoor models to the modularity of our contrast bath systems, every element is designed to support consistent, safe use—whether at home or in a clinical setting.
