What is EMF?

EMF (electromagnetic fields) are invisible energy fields produced by electrically charged objects. They're everywhere — from the Earth's natural magnetic field to your phone, WiFi router, microwave, and yes, your sauna.

EMF is measured in milligauss (mG). For context:

• Earth's natural magnetic field: 250-650 mG
• Standing next to a refrigerator: 2-5 mG
• Using a hair dryer: 60-200 mG
• Holding a cell phone: 10-50 mG
• Quality infrared sauna: 0.5-3 mG

Your infrared sauna produces less EMF than most household appliances you use daily.

What Does the WHO Say?

The World Health Organization (WHO) has extensively studied EMF exposure. Their findings:

The WHO's International EMF Project has reviewed thousands of studies since 1996. They've established exposure guidelines, and the levels in infrared saunas are orders of magnitude below any level of concern.

What About "EMF Sensitivity"?

Some people report symptoms they attribute to EMF exposure — headaches, fatigue, difficulty concentrating. This is sometimes called "electromagnetic hypersensitivity" (EHS).

Here's what the research shows:

A landmark 2005 WHO review concluded: "EHS is not a medical diagnosis. There is no scientific basis to link EHS symptoms to EMF exposure."

This doesn't mean people's symptoms aren't real — they are. But the cause isn't EMF. It's more likely related to stress, anxiety about EMF, or other environmental factors.

Why Do Sauna Companies Market EMF So Hard?

Fear sells. When companies can't differentiate on actual features, they create problems that only they can solve.

Here's the reality:

• All quality infrared saunas have ultra-low EMF. It's standard engineering, not a premium feature.
• There's no meaningful difference between 0.5 mG and 2 mG — both are far below any threshold of concern.
• Companies charging premiums for "low EMF" are often solving a problem that doesn't exist.

It's like bottled water companies marketing "chemical-free water" — all water is already chemical-free in any meaningful sense.

What Should You Actually Care About?

Instead of EMF (which is a non-issue), focus on features that actually impact your wellness:

• Full-spectrum infrared — near, mid, and far wavelengths for complete benefits
• Red light therapy — clinically proven benefits for skin, recovery, and inflammation
• Build quality — wood type, heater quality, craftsmanship
• Warranty and support — lifetime warranty vs limited coverage
• Value — are you paying for real features or marketing hype?

Peak's Position on EMF

We build our saunas with ultra-low EMF because it's good engineering — not because we think EMF is dangerous at these levels.

We won't use fear-based marketing to sell you something. We'd rather focus on what actually matters: full-spectrum infrared, integrated red light therapy, quality materials, and honest value.

All Peak saunas test below 3 mG at body distance. So do most quality competitors. It's table stakes, not a differentiator.
