Sunlighten mPulse Infrared Sauna Review: What Brad Actually Bought and Why

Brad - The Mechanic reviews the tools you use every day. He owns a Sunlighten mPulse two-person infrared sauna.

I bought a Sunlighten mPulse two-person infrared sauna eighteen months ago. I was sceptical. I am less sceptical now.

The research on infrared sauna use in men over 50 is more substantial than most people realise. Cardiovascular benefits comparable to moderate exercise. Measurable reduction in cortisol. Improved deep sleep onset. These are not claims from sauna manufacturers - they are outcomes from peer-reviewed studies including a 20-year Finnish cohort that found regular sauna use correlated with significantly reduced cardiovascular mortality.

None of that made me buy one. What made me buy one was a persistent lower back issue that heat, and only heat, reliably resolved.

Infrared Versus Traditional Sauna

Traditional saunas heat the air to 80 to 100 degrees Celsius. You breathe hot air and sweat from the outside in. Infrared panels heat your body directly at 45 to 60 degrees Celsius. The cabin temperature is lower but the penetration depth is greater - infrared wavelengths reach 4 to 5 centimetres below the skin surface.

For most men over 50, the lower ambient temperature is the practical advantage. A 20-minute infrared session at 55 degrees is comfortable in a way that a traditional sauna at 90 degrees is not for everyone.

Why the Sunlighten mPulse

The mPulse is Sunlighten's full-spectrum model. It delivers near, mid, and far infrared wavelengths from separate panels, each targeting different tissue depths and clinical outcomes. Near infrared for cellular repair and skin health. Mid infrared for circulation and inflammation. Far infrared for core temperature elevation and detoxification. You can run all three simultaneously or target specific wavelengths depending on what you are trying to achieve.

The construction is clear western Canadian hemlock. Low EMF output is independently tested and published by Sunlighten - not a manufacturer claim, a verified specification. The digital control panel allows precise temperature and wavelength selection. Preheat time is approximately 10 to 15 minutes from cold.

Sunlighten ships globally and offers direct consultation before purchase. Contact them through their website for current pricing in your region. It is not an impulse purchase. I spent two years reading about it before I bought it. I have not questioned the decision once.

The Two-Person Size

Buy the two-person model. Not because you will necessarily use it with someone else. Buy it because you need the space to stretch, to change position, to use it without feeling compressed. The one-person cabin is genuinely small. The two-person is a functional space.

What to Look For When Comparing Models

The panel technology is the most important specification. Full-spectrum infrared includes near, mid, and far infrared wavelengths. Far infrared is what most entry-level saunas provide. Full-spectrum is worth paying for.

Low EMF output is the second specification to check. Infrared panels produce electromagnetic fields. The better manufacturers publish tested EMF readings. Look for units with independent testing certification, not manufacturer-only claims.

Wood is cedar or hemlock. Both are correct. Avoid units with thin panel construction - they lose heat and require longer preheat times.

The Professional Choice

Sunlighten mPulse or Clearlight Sanctuary - full spectrum, low EMF, independently certified. Both ship globally. Both carry strong warranties. Both represent a significant investment. This is the correct choice for regular daily use.

The Value Choice

Far infrared only units from established brands with third-party safety certification. Available through major online retailers globally at a fraction of the full-spectrum price. Functional for recovery and relaxation. Not the same product as the professional choice, but not without benefit.

Installation

A two-person infrared sauna requires a standard domestic power circuit - confirm the specific requirements for your country with the supplier before purchasing. Assembly takes two people approximately two to three hours. No trade is required in most configurations.

Practical Use

I use mine four times per week. Twenty to thirty minutes at 55 to 60 degrees. Enter at 45 degrees while it preheats, read or listen, exit when sweating consistently, cold shower immediately after. The cold contrast is not essential but the sleep effect is noticeably better when I include it.

Frequently Asked Questions

Is infrared sauna safe for men over 50?

Yes for most men. Contraindications include certain cardiac conditions, medications that affect heat tolerance, and recent surgery. Consult your doctor if you have cardiovascular concerns. Start with shorter sessions at lower temperatures and build tolerance.

Where do you put it?

A garage, a spare room, or a covered outdoor area. It requires approximately 1.2 x 1.0 metres of floor space plus clearance on all sides. It is not weatherproof and cannot be installed outdoors uncovered.

How long before I notice a difference?

Most people report improved sleep within two weeks of regular use. Muscle recovery improvement is typically noticeable within the first month.

Does it help with back pain?

Heat therapy has strong clinical evidence for lower back pain management. The infrared penetration depth adds to this. Consult your doctor regarding your specific condition.

Does Sunlighten ship globally?

Yes. Sunlighten ships to North America, Europe, Asia Pacific and beyond. Contact them directly for current availability and pricing in your region.
