  • Full-Spectrum Infrared Therapy

    Covers Near, Mid, and Far Infrared wavelengths to penetrate up to 45 mm beneath the skin, enhancing circulation, detoxification, and deep muscle relaxation.
    Studies show sweat output can increase by up to 80%, with muscle recovery times reduced by 40%, and significant relief for joint pain and chronic inflammation (JAMA Internal Medicine, 2015).

  • AirIonX™ Negative Ion Purification

    Installed at the top ventilation opening.
    Releases over 10 million negative ions per cm³, simulating the clean, revitalizing air of forests and waterfalls.Clinical studies show PM2.5 particles can be reduced by 86% within 20 minutes, and serotonin levels may increase by up to 28%, promoting better mood, anxiety relief, and improved sleep quality (IJERPH, 2018).

  • BioPulse™ PEMF Cellular Therapy

    Installed at the bottom of the sauna.Delivers low-frequency pulses (7–30 Hz) to stimulate cellular repair and energy production.PEMF can boost ATP output by up to 300%, improve microcirculation by 29%, and reduce chronic pain by up to 48% in clinical studies (NASA, 2003–2016).
    Widely used in sports medicine and rehab, PEMF is now integrated into a consumer sauna for the first time.

Over the past decade, cardiovascular disease (CVD)—including coronary heart disease and stroke—has become the biggest killer of human health.

According to statistics released by EurekAlert! in early 2024, nearly half (48.6%) of Americans suffer from some type of cardiovascular disease, including coronary heart disease, heart failure, stroke, and especially hypertension. In addition, the proportion of adults in the United States suffering from hypertension is 46.7%.Recent studies suggest that smart sauna use can ease these conditions and reduce mortality.

FAQs

How does a Sunhaven Infrared sauna work?

Unlike traditional saunas that simply heat the air around you, Sunhaven infrared saunas use advanced infrared technology to warm your body directly. Only about 20% of the heat warms the air — the rest penetrates deeply into your tissue, increasing your core temperature and stimulating natural healing responses.

This targeted thermal energy boosts your lymphatic, immune, and cardiovascular systems, prompting a deep, cleansing sweat that supports detoxification and overall well-being. Since water molecules in your body resonate with far infrared waves, the process also enhances cellular cleansing.

That’s why every Sunhaven sauna is equipped with strategically placed 360° infrared heaters—on the back, sides, and even beneath the legs and feet. This full-body coverage ensures you receive balanced heat exposure, maximize core temperature elevation, and achieve the full benefits of infrared therapy.
How long will it take for me to receive the sauna?

If the product is in stock, it takes about 7-9 days from ordering to receiving the sauna. If it is not in stock, it takes about 45-55 days.
What are the benefits of red cedar to the human body?

Western Red Cedar is an ideal wood choice for saunas due to its exceptional natural properties. It offers excellent resistance to moisture and decay, maintaining stability without warping or cracking even in high-temperature, high-humidity environments. Its moderate thermal conductivity ensures the surface remains comfortable and safe to the touch. Additionally, the wood emits a subtle, pleasant aroma that promotes relaxation and enhances the overall sauna experience. With its warm tones and beautiful grain patterns, Western Red Cedar brings both functionality and natural elegance to any sauna space.
What are the specific health benefits of full-spectrum infrared saunas?

Full Spectrum Infrared saunas combine near (NIR), mid (MIR), and far (FIR) infrared wavelengths to deeply penetrate body tissues, promoting detoxification, pain relief, improved circulation, and healthier skin. A study published in the Journal of the American College of Cardiology found that daily use of far-infrared saunas for two weeks reduced systolic blood pressure by an average of 11 mmHg. Another study from Japan showed that patients with chronic pain experienced an average 70% reduction in pain levels after four weeks of infrared sauna therapy. This gentle yet effective heat treatment also helps relax the nervous system, improve sleep quality, and support metabolism and weight management.
Warranty period and service life?

Our warranty period is 8 years. Generally speaking, the service life of a sauna is 10-15 years.
How is the sauna transported?

The sauna will be disassembled and packed in wooden boxes for delivery by truck. Please note that with our free shipping plan, the boxes will be delivered to your doorstep curbside. If you need it delivered to your home, please choose white glove service. We will charge an additional fee.
