Infrared Saunas: A Smarter, Gentler Way to Sweat
You’ve probably heard of infrared saunas—maybe at a spa, on a wellness podcast, or from someone who swears by them after a long run. But what exactly are they? And how do they differ from the more familiar, wood-panelled hot box you’d find in a gym or spa?
If you’re weighing up whether to add a sauna to your home or just curious about the buzz, this guide walks you through everything you need to know: how infrared saunas work, how they feel, what makes them unique, and whether they’re worth investing in.
So, What Is an Infrared Sauna?
Let’s start with the basics. Traditional saunas heat the air around you. Infrared saunas work differently—they use gentle light waves to warm your body directly, without needing to superheat the room.
This means the air temperature stays lower, usually around 40-60°C. But you still get a deep, satisfying sweat. For many people, it’s a more comfortable and accessible way to experience the benefits of heat therapy.
The Three Types of Infrared Heat (and Why They Matter)
Infrared heat isn’t all the same. It’s divided into three wavelengths, each penetrating the body to different depths:
- Near Infrared (NIR): Focuses on the skin’s surface—often linked to skin rejuvenation and healing
- Mid Infrared (MIR): Reaches soft tissue and supports circulation and muscle recovery
- Far Infrared (FIR): Penetrates deepest, warming joints and encouraging full-body relaxation
The best infrared saunas combine all three for what’s called full-spectrum infrared. This gives you a broader range of potential health and recovery benefits in one session.
| Layer Name | Approximate Depth | Infrared Penetration |
|---|---|---|
| Epidermis | 0.1–0.3 mm | Near Infrared (NIR) |
| Dermis | ~1.5–2 mm | Mid Infrared (MIR) |
| Subcutaneous Fat | 3–10 mm | Far Infrared (FIR) |
| Muscle Layer | 10 mm+ | Far Infrared (FIR) |
What Does It Feel Like?
If you’ve ever found a traditional sauna too hot, dry, or stifling, infrared may be your ideal alternative. Because it warms the body directly, the experience is gentler—more like soaking up the sun on a warm day than sitting in a blast furnace.
You’ll start to sweat gradually within 10–15 minutes, and most people stay in for around 30–45 minutes depending on preference. There’s no harsh humidity or heat shock—just a slow build of warmth that encourages you to relax, breathe deeply, and switch off for a while.
What Are the Real Benefits?
Plenty of people use infrared saunas as part of their wellness routine, and while experiences vary, the following are among the most consistently reported benefits:
- Muscle and Joint Recovery: Infrared heat reaches deep into muscles and joints, which may help reduce inflammation, ease soreness, and support recovery after exercise or injury.
- Improved Circulation: The rise in body temperature gently increases heart rate and blood flow—similar to the effects of light cardio, but without breaking a sweat on the treadmill.
- Stress Relief and Sleep Support: Time in an infrared sauna encourages your body to wind down. For many, it becomes a calming daily ritual that improves sleep quality and supports mental wellbeing.
- Healthier, Brighter Skin: Sweating helps clear pores, and the improved circulation may support that healthy post-sauna glow. Some users report clearer, more balanced skin over time.
- Creates a Consistent Wellness Ritual: Beyond the physical benefits, making space for a regular sauna session is a chance to unplug and reconnect with yourself—something we all need more of these days.
Infrared vs Traditional Sauna: What’s the Difference?
| Feature | Infrared Sauna | Traditional Sauna |
|---|---|---|
| Heat Source | Infrared light | Heated air or steam |
| Typical Temp | 40–60°C | 70–90°C |
| Heat Sensation | Direct-to-body, gentle | Ambient, intense |
| Warm-Up Time | Quick | Slower |
| Comfort Level | Mild and relaxing | Hot and occasionally overwhelming |
| Sweat Response | Gradual, deeper | Quicker, surface-level |
Is an Infrared Sauna Right for Everyone?
Infrared saunas are generally safe for healthy adults, but a few considerations are worth noting:
- Stay hydrated. You’ll sweat more than you realise.
- Medical conditions? If you’re pregnant or managing heart-related issues, speak to your GP first.
- Do your research. Not all saunas are built to the same standard—look for low EMF output, quality materials, and full-spectrum functionality.
Should You Get One for Home Use?
If you're building a personal wellness space—or just want a better way to unwind after a long day—then yes, a home infrared sauna is absolutely worth considering.
Many models are compact and easy to install, fitting into spare rooms, garages, or garden buildings. You don’t need plumbing, and most plug into a standard power supply. Once it’s in, it’s yours to use whenever you like—no spa bookings, no waiting.
