Love Health Benefits Plus

Peak Infrared Sauna Health Benefits

Our 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 our infrared saunas a powerful tool for overall wellness, helping you feel healthier inside and out.

How long is the power cord and where does it come out of the unit? Plus

The cord is approximately 9 feet long and it comes out of the top of the unit at the back in the center.

What is chromotherapy and what does it do? Plus

Chromotherapy, also known as color therapy, is a form of alternative therapy that uses colors to improve physical and mental well-being. The idea behind chromotherapy is that different colors have specific wavelengths and energy frequencies, which can influence a person’s mood, emotions, and even health when absorbed by the body. Each color is believed to have unique healing properties.

  • Red: Stimulates energy, vitality, and circulation.
  • Orange: Promotes creativity, enthusiasm, and emotional balance.
  • Yellow: Boosts mood, self-confidence, and concentration.
  • Green: Known for its calming and balancing effects, aiding in relaxation and stress relief.
  • Blue: Soothes anxiety, promotes calm, and helps with sleep disorders.
  • Indigo: Encourages deeper levels of relaxation and introspection.
  • Violet: Supports mental clarity and spiritual awareness.
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.

What is the difference between medical-grade and non-medical grade red light therapy? Plus

When it comes to red light therapy, not all saunas are created equal. Many competitors advertise “red light therapy” but use non-medical grade lights that offer little to no real health benefits—often serving more as decorative lighting than functional therapy.

With Peak Saunas, you’re getting true medical-grade red light therapy—the same standard used in clinical treatments for pain relief, skin health, and inflammation reduction.

When you invest in a sauna for your health, don’t settle for decorative red lights that don’t work. Choose Peak Saunas with medical-grade red light therapy for clinically backed results—so you can recover faster, feel stronger, and truly optimize your wellness.

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. 

What is the difference between the Hemlock wood and Red Cedar? Plus

Both Hemlock and Red Cedar are excellent choices for saunas, but they offer distinct characteristics that cater to different preferences and needs.

Hemlock Wood is a light-colored, non-aromatic wood known for its smooth texture and durability. It’s an affordable, versatile option that stays cool to the touch and resists warping, making it ideal for those who prefer a clean, neutral aesthetic without strong scents.

Red Cedar, on the other hand, is a premium wood option with a rich, warm tone and a naturally pleasant aroma that enhances the sauna experience. While it comes at an additional cost, Red Cedar offers unique benefits that justify the investment:

  • Natural Antimicrobial Properties: Cedar contains natural oils that make it highly resistant to mold, mildew, and bacteria—crucial in a high-humidity environment like a sauna. This means easier maintenance, a longer-lasting structure, and a cleaner, healthier space.
  • Superior Durability: Cedar is less prone to cracking and warping over time, ensuring the longevity of your sauna.
  • Aromatic Experience: The natural scent of cedar adds a calming, spa-like ambiance to your sauna sessions.

In short, if you’re seeking a premium sauna experience with added durability, low maintenance, and natural antimicrobial protection, Red Cedar is worth the extra investment. If you prefer a more budget-friendly, scent-free option with reliable performance, Hemlock is an excellent choice.

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 150F, go with a Peak Sauna!

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.
