    Love Health Benefits Plus

    Infrared Sauna Health Benefits

    Infrared saunas offer a wide range of scientifically supported health benefits. Unlike traditional saunas, infrared heat penetrates deeper into the body, heating you from the inside out and promoting enhanced detoxification, circulation, and relaxation.

    1. Detoxification: Infrared saunas increase sweat production, helping eliminate toxins like heavy metals and chemicals. Studies show that infrared therapy can boost detoxification by up to 20% more than traditional saunas.
    2. Improved Cardiovascular Health: Regular infrared sauna use has been shown to lower blood pressure, improve circulation, and reduce the risk of heart disease by 46%, according to a study published in JAMA.
    3. Pain Relief & Muscle Recovery: Infrared heat helps reduce inflammation, alleviate pain, and accelerate muscle recovery. Clinical trials report that 70% of patients with chronic pain experienced relief with consistent infrared therapy.
    4. Skin Health & Anti-Aging: Infrared saunas stimulate collagen production, improving skin elasticity and reducing wrinkles. Research shows an increase in skin hydration and a 26% reduction in wrinkles after regular use.
    5. Stress Relief & Better Sleep: Infrared saunas promote relaxation by reducing cortisol levels, leading to better stress management and improved sleep quality. 83% of users report feeling more relaxed and sleeping better after sessions.

    These benefits make infrared saunas a powerful tool for overall wellness, helping you feel healthier inside and out.

    What happens after I place my order? Plus

    As soon as you place your order, you will receive an email from us with your confirmation details. Please keep this email for your records. After we receive your order we will begin preparing your order for shipment. As soon as your order ships, you will receive an email with tracking information. 1-2 days prior to delivery, you will receive a phone call from the delivery team to schedule your delivery appointment. You must be home to accept and sign for the delivery during your appointment as scheduled.

    Can you assemble my sauna for me? Plus

    We do provide a done-for-you assembly service for models up to a 4 Person capacity. This is an additional cost and a separate team from the delivery team. You can add assembly to your order and read more about the service here.

    Do you provide financing? Plus

    We have partnered with Affirm to offer financing options at checkout. Just select Affirm as your payment method in Step 3 at checkout and follow their instructions. You can find more info on the Affirm option here. You can also try Shop Pay Installments as your payment method (also in Step 3) if Affirm does not work for you for some reason.

    How hot do your saunas get? Plus

    Our traditional saunas typically get up to 200F with a basic heater and can get up to 230F with a premium heater. Most of our infrared saunas get up to 140F, but if you want an infrared sauna that gets up to 170F, check out our Finnmark line.

    Can I put my indoor sauna outside? Plus

    Yes, as long as it's not exposed to sun and rain directly. If you don't plan to put it under a covered patio or something similar, we recommend getting a custom outdoor sauna cover for it and keeping it covered as shown.

    What is the difference between the regular model and the Elite? (Low EMF vs Ultra Low EMF) Plus

    Just the heating panels. Otherwise they're identical. The regular low EMF model emits less than 8mG and the Elite version emits less than 3mG. If you’re not familiar, EMF stands for electromagnetic frequency and you can think of it kind of like radiation. Long story short, the less EMF you expose yourself to, the healthier you’ll be, so it’s always best to go with the Elite version if you plan to make a habit out of using your sauna, and you can afford the upgrade.
