Tour the mPulse Discover Intelligent Sauna
The mPulse Discover blends luxury design with intelligent sauna technology. It features patented SoloCarbon heaters for high infrared output and ultra-low EMF, integrated red light and near-, mid-, and far-infrared. Celliant fabric heater covers line interior walls for infrared reflection. Thick insulation, kiln-dried wood and recessed chromotherapy lighting create a more refined, immersive experience. With customizable programs and intuitive tablet controls, the mPulse Discover transforms self-care into a science-backed ritual.
- Chromotherapy. Enhance your sauna experience and transform your mental well-being with chromotherapy, or color therapy, the science of using colors to adjust body vibrations to frequencies that result in health and harmony. Chromotherapy works on various energy points to help balance your body via the full spectrum of visible light.
- Craftsmanship and Beauty. Elements like the glass corner and subtle details of fine craftsmanship create a beautiful experience that elevates the ambiance beyond compare. Our magnetic system seals the extra-thick walls to insulate your cabin so that it feels supremely silent and strong; a well-contstructed wellness sanctuary.
- 6 Wellness Programs. You determine the wellness experience you want. Everyone has different and changing desires. The control panel empowers all its users to select from six programs created from clinical research to deliver each wavelength at the optimal dosage to help your body with whatever you need each time you use it.
- Red/NIR LED Panels. In mPulse saunas, LED panels give you your own red/near infrared light therapy tool, strategically placed for optimal therapy. Sunlighten used NASA research to develop an LED array of single wavelength red light and near infrared with minimal variability and undetectable heat and light. A single blue diode lets you know it’s on.
- In-Sauna Entertainment. Tablet provides one-touch access to the six pre-installed health programs or you can customize your own program. Wi-Fi connectivity allows seamless integration and pushed software updates with ongoing new features. You can also download apps from the Google Play store so you can watch your favorite streaming services or listen to your music or podcasts.
Choose today’s wellness goal. mPulse handles the rest.
What your body needs changes day to day. PulseIQ controls the intensity and depth of each wavelength to deliver targeted infrared energy, so you get the wellness benefits you need to feel better every day. Choose a program from the sauna screen or Sunlighten app, settle in, and let your mPulse Intelligent Sauna do the work.

Frequently asked questions about the mPulse Discover, our 4-person sauna
What is PulseIQ?
PulseIQ™ is Sunlighten’s patented infrared intelligence platform. It delivers four distinct wavelengths independently: red light, near-infrared, mid-infrared, and far-infrared. Each is controlled and delivered separately, not blended, so your body receives the right type of infrared energy at the right depth and intensity. This leads to greater absorption which fuels faster recovery, deeper relaxation, better sleep, weight loss and more noticeable wellness results.
What makes mPulse different from other infrared saunas?
Most infrared saunas deliver blended full spectrum or heat. mPulse®, powered by PulseIQ™, separates and controls red, near-, mid-, and far-infrared wavelengths so your body receives more precise, targeted energy. The result is more usable infrared your body can absorb and more effective wellness results.
How does mPulse personalize each sauna session?
PulseIQ™ controls the intensity and depth of each wavelength to deliver targeted infrared energy based on your wellness goal. Built-in, science-backed programs guide each session, so your sauna adapts to what your body needs that day. Choose from Detox, Weight Loss, Heart Health, Relaxation, Muscle Recovery, Anti-Aging.
Why does separating infrared wavelengths matter?
Each wavelength does something different in your body:
- Red light → supports skin health
- Near-infrared → boosts cellular energy and recovery
- Mid-infrared → improves circulation and muscle recovery
- Far-infrared → raises core temperature and supports detox
Most full spectrum saunas blend these wavelengths together into one output. That creates heat, but it limits control.
PulseIQ delivers each wavelength separately at the right intensity and depth. Your body receives more precise, usable infrared energy so you get more benefits and feel better, faster.
PulseIQ™ controls the intensity and depth of each wavelength to deliver targeted infrared energy based on your wellness goal. Built-in, science-backed programs guide each session, so your sauna adapts to what your body needs that day. Choose from Detox, Weight Loss, Heart Health, Relaxation, Muscle Recovery, Anti-Aging.
What are the benefits of infrared saunas?
Infrared therapy supports whole-body wellness by gently increasing your core body temperature by up to 3 degrees, which promotes a deep, detoxifying sweat at the cellular level.
Sunlighten infrared saunas support:
- Detoxification
- Weight management
- Muscle recovery
- Restful sleep
- Anti-aging processes
- Heart health
- Immune function
- Relaxation and stress relief
- Inflammation
- Brain and cognitive health
- Gut and digestive health
Red light therapy complements these benefits by energizing cells at the mitochondrial level to help repair tissue, reduce inflammation, improve skin clarity, enhance sleep quality, and support immune resilience. Together, these therapies work synergistically to optimize overall health and vitality.
Does the mPulse sauna include red light therapy?
Yes. The mPulse Smart Sauna collection includes full-spectrum infrared (near, mid, and far) along with integrated red light therapy to help support full-body wellness and skin health in one seamless session.
How do I install the mPulse sauna?
Sunlighten saunas are designed for simple DIY assembly and typically take 1–2 hours to install with two people. While professional installation isn’t required, our team can help you find a local service provider if you prefer additional support.
Can the mPulse 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.
How long should my infrared sauna session be?
Most people enjoy sessions lasting 30–45 minutes, three to four times per week. Saunas are safe to use daily and can be tailored to your comfort levels and wellness goals.
Hydration tip: Drink at least 8 oz of water before your session, and follow up with 24 oz or more of water or an electrolyte-rich beverage afterward to replenish fluids.
Always listen to your body and adjust session frequency and temperature as needed.
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.
