What researchers are learning about infrared heat and red light

For education only, not medical advice. Studies cited used red/near-infrared light devices and conditions that may differ from a sauna session. Talk to your doctor about any health condition.

PTSD & Trauma: What Light Research Is Showing

PTSD involves a stress system that stays switched on: the fear response fires in safe situations, and the brain struggles to tell danger from safety. Many people use a warm, quiet sauna session as a daily wind-down ritual, a set time to slow down, breathe, and let the body settle.

The research on light is earlier-stage but striking. In the 2021 Molecular Psychiatry study, rats given transcranial photobiomodulation (red/near-infrared light aimed at the head) right after a frightening event kept an accurate memory of where the danger happened, and in a model of repeated trauma they did not develop PTSD-like symptoms. This was an animal study using a targeted light device, not a sauna, and human trials are still needed. It is one reason researchers see light therapy as an area worth watching.

Menopause & Pelvic Health: Red Light Research Without Hormones

Participants in the 2026 PLOS ONE study received eight weekly 30-minute sessions of 660nm red light. Their Vaginal Health Index scores improved at every follow-up, every participant reached the non-atrophic range three months after treatment ended, and urinary symptom scores also improved. No adverse events were reported.

Important context: the light in this study was delivered internally by a small medical light guide, not by a sauna panel, and there was no control group. What it adds is evidence that red light in the 660nm range can change tissue in a measurable way, without hormones. If you are managing menopause symptoms, talk with your doctor about which options fit you.

Depression & Heat: A Surprising Clinical Trial

The study enrolled adults with major depressive disorder who were not taking psychiatric medication. Half received one session of whole-body hyperthermia, which raised their core body temperature; the other half received a sham session that copied everything except the intense heat. Compared with sham, the heat group had significantly lower depression scores at weeks 1, 2, 4, and 6.

One explanation researchers propose is that warmth-sensing pathways in the skin signal brain areas involved in mood. A sauna session warms the body more gently than the device used in the trial, and this study does not show that a sauna has the same effect. It is an early but well-designed result in a growing field. Depression is a serious condition, so keep working with your care team.

Fibromyalgia: Infrared Heat in a Sham-Controlled Trial

The trial enrolled 41 adults with diagnosed fibromyalgia. The treatment group had six sessions of water-filtered infrared-A whole-body heat over three weeks, reaching an average peak body temperature of about 38.7°C (101.7°F) for roughly 15 minutes. The sham group had the same procedure with an insulating foil that blocked most of the infrared. Pain was significantly lower in the heat group at week 4 and again at week 30.

The study used a medical infrared hyperthermia device, which heats the body more than a typical sauna session. It was small, but sham-controlled results like this are rare in fibromyalgia research, which is why infrared heat is getting a closer look. If you live with fibromyalgia, ask your doctor how heat could fit your plan.

Concussion & Brain Injury: Early Light Therapy Research

Seven years after a car accident, the first patient could focus on computer work for about 20 minutes. After eight weekly light treatments, that grew to about three hours, and she kept up nightly home treatments for years; when she stopped for more than two weeks, her symptoms returned. The second patient, on medical disability after repeated head trauma, returned to full-time work after four months of nightly treatments.

Two case reports are the earliest stage of evidence: there was no control group, and the light (633nm red and 870nm near-infrared) came from LED clusters placed on the scalp, not from a sauna panel. Larger studies have since continued to explore light therapy for brain injury. For now, it is an area to watch rather than a proven treatment.

Hashimoto’s Thyroiditis: What Light Therapy Studies Report

The review, in the International Journal of Molecular Sciences, pooled six human studies published between 2010 and 2025. Across them, light therapy was associated with fewer thyroid autoantibodies, better thyroid hormone measures, and lower levothyroxine dose needs. One sham-controlled trial found better oxidative-stress markers and quality of life, without short-term hormone changes.

The authors are clear about the limits: few studies, different protocols, and frequent use of selenium or vitamin D at the same time, so larger randomized trials are needed. The light in these studies was applied directly over the thyroid, which is different from a full-body sauna panel. Never change thyroid medication without your doctor.

Skin: Measurable Collagen Gains From Full-Body Red Light

Participants had 30 sessions of either red light (611–650nm) or a broader red-to-near-infrared spectrum (570–850nm). Blinded reviewers rating before-and-after photos confirmed significant improvement in the treated groups compared with controls, and ultrasound showed higher collagen density in the skin. The broader spectrum did no better than red light alone, and no safety problems were reported.

Unlike many light-therapy studies, this one used large-area, full-body light sources, the same idea as a full-body red light panel. Collagen keeps skin firm and declines with age, so a measurable increase is a meaningful result. As in the study, consistency matters: participants had two sessions a week for about 15 weeks.

Heart Failure & Blood Vessels: Sauna Research From Japan

Twenty patients with moderate heart failure sat in a 60°C (140°F) dry sauna for 15 minutes, then rested under a blanket for 30 minutes, every day for two weeks. Symptoms improved in 17 of the 20. Their arteries widened better in response to blood flow, and BNP, a blood marker of strain on the heart, dropped. A comparison group that rested in a normal-temperature room showed no change.

This approach, later known in Japan as Waon therapy, was done under medical supervision, and the study was small and not randomized. A 60°C setting is within the normal range of an infrared sauna. If you have heart failure or any heart condition, talk with your cardiologist before starting sauna sessions.

Overview & What's Included Plus

The Peak Fuji is a 2-person indoor full spectrum infrared sauna for buyers who want the best overall value and setup in the Peak range. It reaches a true 150°F, includes a full-body medical-grade red light panel as standard, runs from the Smart Life Wi-Fi app and the Peak RLT app, runs on a dedicated 120V/20A circuit, and ships free in a protective crate with a 7-Year Warranty.

Why people actually buy our saunas: the long game.

Regular sauna use is one of the most-studied longevity habits in the world. Researchers followed 2,315 middle-aged men for 20 years and found that those who used a sauna 4–7 times a week had 40% lower all-cause mortality and 50% lower fatal cardiovascular disease than once-a-week users (Laukkanen et al., JAMA Internal Medicine, 2015); a follow-up reported a 65% lower rate of Alzheimer’s disease (Age and Ageing, 2017). The benefit tracked with frequency — which is the entire argument for owning a sauna instead of booking one. The Fuji is built to make that frequency effortless: room for two, so the habit is shared instead of solitary.

Fuji — The 2-person, in aromatic red cedar.

The Fuji is our two-person cabin in premium Canadian red cedar — the aromatic, naturally moisture-resistant wood prized in traditional saunas — paired with full-spectrum infrared, an XL medical-grade red-light wall, and a real max of 150°F. It’s our most-reviewed sauna.

Medical-grade red light, where it works. Real therapy, not decorative LEDs — an X-large medical-grade panel on the front wall, positioned for full-body coverage while seated and designed to support skin, circulation, and recovery. Most brands hide a token strip in the ceiling; the Fuji puts it where it works.

360° full-spectrum infrared heat. A hybrid of carbon FAR panels plus halogen + quartz emitters delivers near, mid, and far wavelengths (700–25,000nm) for even, full-body warmth — built to support deep relaxation and recovery.

Max 150°F+. Reaches 150°F — hotter than the many infrared models capped at 140°F — for a deeper, more satisfying sweat.

Run it from your phone. Preheat from anywhere; adjust temperature, lighting, and session length in the Smart Life Wi-Fi app (iOS & Android, 2.4 GHz Wi-Fi). Red light sessions run from the Peak RLT app.

An atmosphere for the ritual. Two HiFi Bluetooth speakers, dual-level LED accent lighting, built-in chromotherapy, and a smart oxygen-ionization system that freshens the air during and after each session — plus a foot-reflexology heater for head-to-toe warmth.

Built to last. Hand-finished Canadian red cedar — naturally aromatic, moisture-resistant, and built to last. Clasp-together assembly. Runs on a dedicated 120V / 20A outlet.

Health benefits & the research Plus

What the research actually shows

Regular sauna bathing is one of the most-studied longevity habits in the world. The strongest evidence comes from a 20-year Finnish cohort study that followed 2,315 middle-aged men and compared those who bathed 4–7 times a week against once-a-week users.

  • Longevity. 40% lower all-cause mortality among the most frequent users (Laukkanen et al., JAMA Internal Medicine, 2015).
  • Cardiovascular. 50% lower fatal cardiovascular disease in the same group (same study); a later analysis also linked frequent sauna use to lower incidence of hypertension (American Journal of Hypertension, 2017).
  • Brain health. 65% lower rate of Alzheimer’s disease and dementia among the most frequent users (Age and Ageing, 2017).
  • Recovery and relaxation. Heat exposure raises circulation and is widely used for post-exercise recovery, muscle relaxation, and winding down at the end of a day.

Two things worth knowing about this research. It studied sauna bathing generally — largely traditional Finnish saunas — so it is evidence about the habit, not about any one brand. And the benefits tracked with frequency: 4–7 sessions a week, not the occasional visit. Consistency at that level is difficult to buy by the session, which is the practical case for owning one.

Peak saunas are wellness products, not medical devices, and are not intended to diagnose, treat, cure, or prevent any disease.

You won’t be disappointed

I honestly have spent years researching different saunas and trying to decide on a brand that had everything I wanted. It’s a huge purchase, so something to not just rush into! I could not be happier! The Fuji is absolutely perfect and fits all of my wants and needs, and I cannot say enough about their customer service! I have already recommended the company and this particular sauna to many friends and family:)

One of my best purchases ever!

I absolutely love my Peak Fuji-2 Sauna! We received our order in 5 1/2 weeks & we were pleasantly surprised as to how easy it was to assemble. I currently use it 3-4 times per week. I love all of the features that are included with the sauna especially the red light panel, the music system & the ability to heat the sauna up remotely using the app on my phone. The only thing that I would request to be changed is the drink holder is too small, it will not accommodate my Stanley cup (which is a fairly popular sized cup)! Also, I’m so glad that I paid the extra for the cedar! It smells so good! I highly recommend purchasing a Peak Sauna & the customer service has been awesome from start to finish!

Thank you so much for taking the time to share this! We love hearing that your Fuji has become such a regular part of your routine and that you’re enjoying all the features. And we totally agree, there’s just something about that cedar smell! 😊

We also really appreciate the feedback on the cup holder. A Stanley-sized cup holder is officially on our radar! 😂 Thank you again for choosing Peak and for trusting our team. We’re so happy you’re loving your sauna!

So far so good, once the Sauna showed up it has

So far so good, once the Sauna showed up it has been great. It was a challenge as for the time frame that it took to get the sauna. Other than that everything was great. We ordered in April and did not receive the unit until the middle of July.

Hi Greg, thank you for your feedback and patience during the delivery process. We're glad to hear you're enjoying your sauna. If you need any assistance moving forward, please don't hesitate to reach out!

Fuji Sauna Review

We’ve had our Fuji 2 person sauna for a couple of months. From the first call through today the staff of Peak Sauna have been superb! Assembly was just as described, quick (about 1.5 hrs) to open the box and complete the assembly. We use the sauna 1-2 times a day, it is almost addictive. I would highly recommend this sauna to anyone looking to purchase a sauna. The red light therapy is a great addition!

Hi there! Thank you so much for sharing your wonderful experience with the Fuji sauna. We're thrilled to hear you're enjoying it and that our team could assist you well. Enjoy your relaxing sessions and the red light therapy!

Very Pleased

We are very pleased with our purchase of the Fuji model. I have been using it for two weeks and feel like my sleep quality has already improved. I am so glad I went with the 2 person size as it is big enough for my husband and I without feeling claustrophobic. Plus when it is just me I feel like I can stretch out a bit. We are impressed with the quality of the materials even the sound system is great which I didn’t expect. My son helped us lay the big crate down, but we did the rest just the two of us and it was quite simple to put together. Looking forward to many years of this working for us!

Hi Amy, thank you so much for sharing your wonderful experience! We're thrilled to hear the Fuji sauna is making a positive difference for you and your family. Enjoy many relaxing sessions ahead!

Greatest Wellness Investment!

We bought our sauna after visiting a spa, listening to several podcasts, lots of research and settled on the Peak Fuji. Absolutely the best wellness investment we have made. Everything else has improved. The only thing: we wish we’d have bought the three person just to have more space and potentially, partially lay down. Aside from that, zero issues. We love our sauna and we’ve been using it 3-5x’s per week for around six months.

Hi Nick, we're thrilled to hear how much you love your Peak Fuji sauna! It's fantastic that it's become such a positive part of your wellness routine. Thanks for sharing your experience and your thoughtful feedback about the space — we appreciate it! Enjoy many more relaxing sessions.

Peak Fuji 2-person sauna

My wife and I love our Peak Fuji 2-person sauna with Full-Body Medical-Grade Red Light Therapy & Smart WiFi App Control.

It is so easy to use as I turn the sauna on remotely using my smart phone and by the time I change clothes and jump into the sauna is up to temperature.

All the literature on the website describing the sauna is spot on. I even talked to a peak representative prior to ordering and she was very friendly and helpful.

The drivers delivered the crated sauna into my garage and me and my son assembled it in the garage and I was using that night.

Super great product.

Thank you for your kind review of the Fuji, Jeffrey! We are thrilled to hear that you and your wife are enjoying using it and that it has met all your expectations. We are also glad to hear that our literature accurately described the product and that our representative was able to assist you with any questions before your purchase.

We take pride in our easy-to-use and convenient sauna, and we are happy to hear that it has been a great addition to your home. We hope you continue to enjoy its benefits for years to come. Thank you for choosing Peak and for sharing your positive experience with us.

Wonderful company to deal with and great product

After a lot of comparison shopping, we decided to go with Peak Saunas for our in-home sauna purchase. They could not have been easier to work with and helped us with the selection and with timing the shipment so that we could be home and make sure the space was ready for installation. The crate arrived as described in great shape, and assembly was relatively straightforward. The documentation and videos they sent us were also super helpful. The sauna itself works just as described and looks even better in person. We all love this new addition to our basement fitness area. Peak Saunas has been friendly and professional throughout the entire process.

Thank you so much for your kind words and for choosing Peak Saunas, Leslie! We are thrilled to hear that you had a wonderful experience with our company and that you are enjoying your new sauna. Our team takes pride in providing excellent customer service and we are glad that we were able to assist you in choosing the right sauna for your needs. Thank you for trusting us and for being a valued customer.

Great addition!

Love this thing! It's really helped my wife and I evening routine. No tv; just a sauna/red light session, shower, and bed. The only pain was figuring out how many outlets were branching from our 20 amp breaker and move the sauna to that specific outlet and cap off the others. Other than that, we got it done! Now, the plunge is on the other side of the garage for mornings, sauna on the opposite side for evenings. We're slowly getting the 'wellness' space together. Thanks Peak Saunas!

Thank you for your positive feedback, Scott! We're thrilled to hear that the Fuji has been a great addition to your evening routine and has helped with your wellness journey. We apologize for any difficulties you had with setting it up, but we're glad you were able to get it done. It sounds like you have created a fantastic wellness space and we're happy to be a part of it. Thank you for choosing Peak Saunas!

Medical Grade Redlight???

I have asked for Verification Report from Peak regarding Redlight wavelength accuracy and I’m not getting much response….am told I am not allowed to know the name of the manufacturer and they don’t have reports to send me verifying this….. kinda disappointing!!!

Pat, thank you for the thoughtful review and for sticking with us through the process. We’re a small team and we truly care about every order, so it means a lot that you recognized that.

We appreciate the feedback on the lead time, freight delay, and ionizer instructions. We’re continuing to improve our timelines, communication, and manuals so future customers have an even smoother experience.

I’m glad your Fuji is working great now and that you’re enjoying the build quality and benefits. Welcome to the Peak Saunas family, and please reach out anytime if you need tips or support!

Peak Fugi Sauna

I've been using my Peak Fugi Sauna for a couple months now and the experience and results have been excellent. I'm retired and very active mainly with regular pickleball play and even with a stretching routine every day, was experiencing typical aches and pains. I decided to investigate if an infrared sauna would be beneficial and which one offered the best value.

I didn't know much about the infrared sauna, so I developed a typical buyer compare matrix with the different sauna companies. I learned about and evaluated the various compare items (FIR-MIR-NIR source and wavelength, emissivity, red light therapy, wood type, warranty, service, price, delivery, etc. and the Peak product came out ahead mainly on the price-value equation where the technical features were comparable to higher price alternatives. I concluded that other higher price alternatives had higher marketing-sales commission costs but no noticeable technical advantages.

I worked with Peak customer support personnel throughout the process and found them all to be responsive, knowledgeable, and a pleasure to work with. I live on a private road and had to use a tractor to get the sauna crate from the shipping truck onto the tractor and transport it 1/2 mile down the private road. Peak Customer Support Personnel (Rebecca, Molly, and Danielle) explained how I needed to safely transport it to my house. When I assembled the sauna on Saturday, I had some labeling questions, and I was pleased to get responsive answers and phone calls on the weekend to help me.

I have a routine now with my sauna use frequency, temperature, and duration time, and have noticed the aches and pains are less intense compared to before I bought the Fugi Sauna. I would highly recommend anyone considering an infrared sauna to give Peak Saunas their close consideration.

Thank You,

Terry

Thank you for the wonderful review, Terry! We're so glad to hear the Fugi Sauna has become a valuable part of your wellness routine and is helping with those post-pickleball aches. We really appreciate your thoughtful research and kind words about our team — Rebecca, Molly, and Danielle will be thrilled to hear your feedback. Thanks again for choosing Peak and for recommending us!

Amazing!!!

So first off I want to say the sauna I received is amazing. It is definitely a two person job in assembly took me about an hour to put together. The instructions are not the best but if you like pictures you can pretty much figure it out haha.
The red light therapy does kick off every few minutes which is a little annoying you have to turn it off then back on to use it but other than that it heats up and the Bluetooth works great and I’m always drenched coming out of there. So that’s why I rated it as 4 stars and not 5 because of the red light therapy. But overall great product and highly recommend!

Thank you for the thoughtful review, Matt—we’re so glad to hear you’re loving your sauna overall and that assembly went smoothly! You’re absolutely right about the red light therapy: if the panel is connected to the sauna’s main power, it will automatically cycle off once the sauna surpasses its maximum temperature. This is a built-in safety feature, but we understand it can be a little inconvenient during your session.

Our support team will be reaching out directly with some tips and tricks so you can enjoy uninterrupted red light therapy for the full length of your session without it turning off. We really appreciate your feedback and are glad you’re getting such great use out of your sauna!

Sweating, But Make It Fancy + Smell Like Cedar!

Have I ever used an infrared sauna before I purchased this? No. But someone told me I needed one and this is the one I researched, landed on, and FELL IN LOVE WITH!
First off, the cedar smell. Oh. My. Word. The minute you start unboxing, your room smells like a luxury spa. Honestly, it makes setup fun because you’re basically getting aromatherapy while you work.

Then you get it put together and think, “Holy sauna, this thing is huge.” But you quickly get over it because that giant space? Yeah—that’s YOUR new zen zone. PLENTY of room for me and the hubby.

Now, the red light panel. I’ll be real, my country-boy husband took one look at it and said, “What in the world is that big ol’ red light for?” Fast forward 24 hours and he’s barging in like, “Babe, move over, I need my red "lightning" session—this thing is actually helping that weird skin thing!” (He’s now a believer, SO am I ha.)

For me, it’s all about the peace. I preheat it from my phone while wrangling kids at bath time, then sneak in with my Kindle, some spa music, and sweat like crazy while no one bothers me. That’s 45 minutes of pure bliss—and yes, the cedar smell still makes me stupidly happy every time.

Oh, and the recovery? Unreal. After a heavy lift day, I feel way less wrecked and I sleep like a baby. Honestly, if I knew it would be this good, I’d have bought three.

So yeah—do it. Full send. Zero regrets. Believe the hype, believe the science, and prepare to be the person who casually says, “Sorry, can’t talk, I’m red-lighting.” 😂

Ryan, this might be one of our favorite reviews ever! We’re so glad the cedar aroma, spacious design, and red light therapy have made such an impact (and that your husband is now a believer too 😅). Love hearing how you’ve turned it into your personal zen zone—and we’re thrilled it’s helping with recovery, relaxation, and everything in between. Thanks for sharing your experience in such a fun way—enjoy every “red-lighting” session!

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

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 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.

Can I put an indoor sauna outside on a covered patio or lanai? Plus

No. An indoor model cannot be placed outdoors. Outdoor use of an indoor model voids the warranty. For a patio, deck, or backyard, choose one of our outdoor models: Patagonia, El Capitan, or Kilimanjaro.

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.

How often should I use my sauna? Plus

The research points to frequency. In the 20-year Finnish cohort study, the people who saw the largest differences used a sauna 4–7 times a week; those benefits shrank at 2–3 times and largely disappeared at once a week (Laukkanen et al., JAMA Internal Medicine, 2015). Most Peak owners settle into a 20–40 minute session most days. That cadence is the entire reason owning a sauna beats booking one — it removes the drive, the schedule, and the per-session cost that quietly cap how often you actually go.

Is there real research behind sauna use, or is it just marketing? Plus

There is a genuine body of peer-reviewed research, and it is worth being precise about what it says. The most-cited work followed 2,315 middle-aged Finnish men for two decades and found that frequent sauna bathers (4–7x/week) had 40% lower all-cause mortality and 50% lower fatal cardiovascular disease than once-a-week bathers (JAMA Internal Medicine, 2015), with a follow-up reporting a 65% lower rate of Alzheimer’s and dementia (Age and Ageing, 2017). Those studies looked at sauna bathing as a habit — mostly traditional Finnish saunas — not at any particular brand or at infrared specifically. We think the honest version is more useful than the hyped one: the habit is well studied, and our job is to make the habit easy to keep.

How long until I feel a difference? Plus

Most people notice the short-term effects — deep relaxation, looser muscles, easier sleep that night — within the first few sessions. The longevity research above is about something different: a habit sustained over years, measured across decades. Both matter, and they are not the same claim. Start with sessions you enjoy enough to repeat, and the frequency takes care of itself.
