    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.

    Good quality but heavy assembly

    The sauna is fantastic once it’s set up, but the assembly took longer than I expected. That said, the features are worth it.

    Thank you for your feedback, Benjamin! We're glad you're enjoying the sauna and its features. We appreciate your patience with the assembly process.

    What is red light therapy and what is it good for? Plus

    Red light therapy uses low wavelengths of red or near-infrared light to penetrate the skin and stimulate cellular repair, boost collagen production, and reduce inflammation. It’s commonly used for improving skin health (anti-aging, wrinkles), speeding up muscle recovery, relieving pain, and enhancing circulation. It’s also beneficial for wound healing, hair growth, and even improving sleep and mood by supporting cellular energy production and reducing stress on the body.

    Can you assemble my sauna for me? Plus

    If you prefer not to assemble it yourself, we recommend hiring a local handyman. Thanks to the simplicity of our sauna kits, any handyman team can easily complete the setup with no prior experience required. 

    Do you provide financing? Plus

    We sure do! To access your financing offer, please select Shop Pay Installments as your payment method in Step 3 of the checkout process. Please note that you will need to input a debit card to receive your offer but you can still back out after that step.

    How hot do your saunas get? Plus

    Our traditional saunas typically get up to 195F 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 Collection.

    Can I put an indoor sauna outside on a covered patio or lanai? 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 our custom outdoor sauna cover for it and keeping it covered as shown.

    Can I put an indoor sauna in my unheated garage or basement? Plus

    Yes, these are some of the most common locations customers decide to put our saunas. However, when it is cold outside, the sauna will take longer than normal to heat up to maximum temperature.
