For those living with Long COVID, the virus leaves behind a trail of lingering symptoms that can drastically impact day-to-day life:

And perhaps most frustrating of all? The feeling that no one has answers or knowing what to do.

Enter Far Infrared (FIR) Therapy

Far Infrared (FIR) saunas—specifically the Relax Sauna—are emerging as a promising, science-backed tool to support recovery from viral syndromes like Long COVID.

Unlike traditional saunas that rely on high ambient heat, FIR saunas use deeply penetrating infrared light to warm the body from the inside out. This creates a gentle, therapeutic effect that stimulates core body processes without overheating or stress—making it ideal for those with chronic illness, fatigue, or heat sensitivity.

Let’s break down exactly how FIR therapy supports Long COVID recovery:

Many people with Long COVID show signs of mitochondrial dysfunction—a disruption in the body’s ability to produce energy at the cellular level. FIR therapy can help restore this.

Studies have shown that FIR therapy may enhance ATP production, which gives your body the energy it needs to function and heal. With consistent use, many users report:

One of the hallmarks of post-viral illness is poor blood flow and reduced oxygenation of tissues.

Using FIR light, the Relax Sauna increases heart rate and circulation—similar to light cardio, without the physical effort. This can help:

Better circulation = better healing.

Long COVID is often associated with a dysregulated immune system, including reactivation of other viruses, inflammation, and autoimmune responses.

FIR therapy has been shown to:

This immune-modulating effect can help the body restore balance—without overstimulation.

While FIR saunas offer powerful benefits, going slow is key—especially when you’re healing from chronic illness or viral syndromes. Here’s how to support your body from the start:

1. Hydrate Before and After:  Your body will sweat and release toxins—replace lost fluids with filtered water before and after each session.

2. Add Electrolytes: Support hydration and nervous system balance by adding electrolytes to your water—especially important if you’re prone to dizziness or fatigue.

3. Start Low & Slow: Begin with just 5–10 minutes per session, at lower intensity. As your body adapts, you can slowly increase to 20–30 minutes. There’s no rush—healing isn’t a race.

4. Consider Binders: Sweating mobilizes toxins. Taking a gentle binder like activated charcoal or bentonite clay (under guidance from a healthcare provider) can help reduce detox symptoms and support elimination.

5. Listen to Your Body: Healing happens in layers. If you feel tired afterward, rest. If you feel energized, great! Track your response and adjust accordingly.

We hear from Relax Sauna users every day—people living with post-viral illness, chronic fatigue, autoimmunity, and more.

What they share is powerful:

“I finally feel like I’m getting my life back.”
​“I’m not 100% yet—but I can feel the healing starting.”
​“It’s the only thing that’s helped my fatigue.”

This isn’t just about sweating. It’s about restoring hope, supporting your body, and taking back your quality of life.

The Relax Sauna stands apart from other infrared saunas. Here’s why:

All it takes is 15–30 minutes a day to begin supporting your recovery.

If you’re navigating Long COVID or post-viral illness and looking for natural, gentle tools to support your healing—FIR therapy may be the missing piece.
