Frequently asked questions about the Amplify RED IV, our 4-person sauna
What makes the Amplify RED sauna different from other infrared saunas?
Amplify RED adds integrated red and near-infrared light panels to the full-spectrum infrared sauna experience. SoloCarbon® far-infrared heaters, additional full-spectrum heaters and CELLIANT® heater covers bring light and heat together in one cabin.
Who is the Amplify RED sauna best suited for?
Amplify RED is ideal for high performers, biohackers, and athletes looking for muscle recovery, reduced inflammation, and enhanced full-body resilience. It’s like a high-intensity workout for your wellness routine.
What are the health benefits of using the Amplify RED sauna?
Amplify RED supports muscle recovery, helps reduce inflammation, enhances detoxification, boosts circulation, and promotes overall resilience. The high-intensity heat helps activate these benefits more quickly and deeply than traditional infrared saunas.
How hot does the Amplify RED sauna get?
The Amplify RED has always been our hottest sauna model, giving you the option for the most intense heat. Your overall heat experience depends on several factors, such as where your sauna will be set up, the airflow and ambient air temperature, humidity, and the floor material below the sauna. We’d be happy to advise you on these as you consider Amplify RED.
Does the Amplify RED sauna use full-spectrum infrared?
Yes, Amplify RED delivers full-spectrum infrared—near, mid, and far—combined with extra high heat for accelerated wellness results.
Can I customize my sessions in the Amplify RED sauna?
While Amplify RED is designed for high-intensity heat, it still allows you to adjust session length and temperature, so you can tailor the experience to your preferences. For more customizable options, view our mPulse smart sauna collection.
How does Amplify RED compare to traditional saunas or steam rooms?
Unlike steam or traditional saunas, Amplify RED uses infrared light to heat the body directly rather than the air. This allows for a deeper, more productive sweat at a lower ambient temperature—enhanced by its full-spectrum + halogen heat combo.
Is the Amplify RED sauna safe to use frequently?
Yes. Infrared therapy is gentle and clinically shown to be safe for regular use. Many users enjoy Amplify RED several times a week as part of their health optimization routine.
How long should I stay in the Amplify RED sauna?
Typical sessions range from 20–45 minutes. Start with shorter sessions and gradually increase time as your body adapts to the higher heat and deep infrared penetration. Always consult your doctor or a medical professional for individual recommendations based on your unique health and wellness goals.
Can the Amplify RED sauna be used outdoors?
Our saunas are engineered for indoor use. If you plan to place your sauna outdoors—with or without a roof—a custom sauna cover is required to maintain your warranty coverage. Keep in mind that ambient temperatures can affect preheat time. In colder climates, your sauna may take longer to reach optimal heat levels. For best results, consult our placement guidelines or speak with a Sauna Consultant.
What is EMF, and why does it matter in a sauna?
EMFs (electromagnetic fields) are invisible waves of energy associated with electricity and wireless technologies. Prolonged exposure to high EMF levels may contribute to oxidative stress, fatigue, and other health concerns. Sunlighten saunas are third-party tested by Vitatech Electromagnetics and shown to emit ultra-low EMFs—giving you peace of mind during every session. Learn more about our safety testing and standards here.
How long do Amplify RED saunas take to heat?
All our saunas heat up at a pace that’s safe for the sauna, and for you. Amplify RED is designed to hit its higher target temperatures faster than our other models. In ideal conditions, this can be approximately one degree per minute. You can learn more here.
