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 Shasta is a 1-person indoor full spectrum infrared sauna for daily home use. 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, plugs into a standard 120V outlet, 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 Shasta is built to make that frequency effortless: compact enough to live in a spare corner, so nothing stands between you and a daily session.

Shasta — The 1-person essential.

The Shasta is the full Peak experience in a single-person footprint — full-spectrum infrared, an XL medical-grade red-light wall, and a real max of 150°F, in hand-finished Canadian hemlock. It plugs into a standard outlet, so it’s ready the day it lands.

Included free with every Shasta

  • Lifetime Peak Wellness Club membership — $588/yr value. Guided daily sessions, 30-day programs, an expert research library, and session tracking — free for life.
  • Free delivery, shipped in a custom protective crate.
  • 7-Year Warranty + lifetime U.S.-based support.
  • $1,799 medical-grade red-light wall — included standard.
  • Peak Welcome Box to start your practice from day one.

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 Shasta 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 hemlock — non-toxic and naturally durable. Clasp-together assembly. Plugs into a standard 120V household outlet — no electrician, no dedicated circuit.

Order your Shasta today — and start the habit the research keeps pointing to.

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.

Love my new Peak Sauna - Shasta

I have had my new sauna for almost 3 weeks now, using it most days (and sometimes twice a day - once to help wake up at a higher heat, shorter time, at night with a lower temp and longer time). It has been amazing. I’ve been using a sauna at a med spa for a year now but only had the chance to get there twice per week previously. I almost bought the same sauna brand they use but I am so glad I didn’t. My Peak Sauna gets so much hotter than theirs and I can feel it easily. It doesn’t take up a lot of room and heats up relatively quickly, and gets hot (much hotter than the stated temperatures). It was easy to put together but the instructions were incorrect and not complete in a couple of areas (I had to call and speak with someone but that was super easy). Other than that, my husband and I put it together in about two hours, even with having to call to figure it out. The longest part was unboxing everything. Very happy with my purchase. It took months of research to finally make a decision and I am very happy with it.

Hi Patricia, we're thrilled to hear how much you're enjoying your Shasta sauna! It’s wonderful that it’s exceeding your expectations and fitting well into your routine. Thanks for sharing your experience and for choosing Peak Saunas!

We’ve had our sauna for about 30 days and really haven’t started any of Peak’s formal programs, but we use the sauna 3-4 times/week. It really makes you feel good and it really relaxes you for bedtime. We love it

Loving my Shasta 1-person sauna in CO!

I love my Shasta. I turned our living room into my Pilates and sauna room! Who needs a living room anyway… it was only used at Christmas time! Having the flexibility to move from workout to sauna in my own home is literally game changing. And… I don’t have to share with any other sweaty person!

This absolutely made us smile 😊 We love hearing how people are creating wellness spaces that truly fit their lifestyle, and your Pilates + sauna + part time living room setup sounds like the dream (and looks it)! The convenience of being able to move from workout to sauna in the comfort of your own home really is a game changer. And not having to share with “any other sweaty person” gave us a good laugh 😂 Thank you so much for sharing your experience with the Shasta — we’re so happy it’s become such a special part of your daily routine!

Love my Shasta

I love my Shasta sauna! I’m using it often. I love to listen to music in my sauna. I like to light up my sauna in different colors. I like the option of using the infrared or the red light therapy panel or both at one time. I’m happy I chose Peak. I had questions prior to ordering, I left a message and Danielle called me back and answered all of my questions. Maybe more than once🙂 I also had questions when we were setting up the sauna, I talked to a couple of different guys and both were very helpful. We communicated through phone and texting.

Thank you so much, Kimky! We love hearing how much you’re enjoying your Shasta—music, lighting, and the flexibility between infrared and red light is exactly how it should be used 🙌

Really appreciate you calling out the team as well—happy we could help every step of the way. Enjoy your sessions!

Doesn't get any better than this!

I am absolutely loving my Peak Saunas Shasta one-person sauna. As a contractor, I’m very familiar with things arriving damaged or not working properly right out of the box, so I was honestly prepared for at least one issue. Instead, delivery was flawless, everything arrived in perfect condition, and the unit fired up beautifully on the first try. Huge relief.

Putting it together was very straightforward (minus one tiny hiccup in the instructions, which was easy enough to figure out), and I was in my first sauna session within a few hours of it arriving. Another big plus: the setup only requires a standard plug - no special electrical work needed - so it was truly plug-and-play. Now I can feel confident recommending this sauna to our clients for their custom gym set ups!

For a small space, this sauna is a dream. It’s compact, looks ****, and blends in perfectly with my existing decor. It has all the features I was looking for in an infrared sauna: it works great with both the manual controls and the app, the red light therapy is a really cool added bonus, and the built-in Bluetooth speakers and color-changing LED strips really round out the experience and make each session feel elevated.

From start to finish, Peak Saunas made this so easy - and now the Shasta is a huge value-add to my everyday routine. I’m using it constantly and couldn’t be happier with the purchase. Thanks, Peak Saunas!

Thank you so much for this incredible review, Kali — it truly means a lot!

We’re thrilled to hear your Shasta arrived in perfect condition, assembled smoothly, and fired up right away. Knowing a contractor was impressed with the quality and plug-and-play setup is the highest compliment. We also appreciate you calling out the features — from the red light therapy to the LED lighting and app controls — we put a lot of care into making the Shasta compact but genuinely premium.

It’s amazing to hear it’s already part of your daily routine and something you’d confidently recommend to clients. We’re honored to be part of your space and your wellness practice.

Thank you again for choosing Peak — we’re here for you anytime!

great product

Danielle has been wonderful in helping set up my sauna. I used a infrared red sauna 2 years at a business in town and loved it so I decided to buy my own one person infared red therapy sauna. I now use it at least 5 days a week vs once a week before purchasing the sauna. I feel the difference of using at a regular basic. If your on the fence, try one out first and you will fall in love with it! I have it in my finished garage and love it there! Love the cushion too!

Sue, thank you so much for the wonderful review and for the shoutout, it has truly been a pleasure helping you get set up. I love hearing that you went from using an infrared sauna once a week to five times a week at home and that you can really feel the difference with consistent use. Your tip to anyone on the fence to try one first is spot on, most people fall in love once they experience how it makes them feel. I am also so glad the one person sauna fits perfectly in your finished garage and that you are loving the cushion too. Thank you again for trusting us and for being such a dedicated sauna user.

I've only ever sauna-ed at spa spaces, never at home - which is a game changer. My neighbour recently got this - sweat before work, or after a workout (or karaoke) from your home is luxe! Plus the red light therapy is built in future focused! I'm hooked!

Love this, Lucy! We’re so glad you’re enjoying the at-home sauna experience—it really is a game changer. Happy to hear the built-in red light therapy is already part of your routine. Here’s to many more sweat sessions (and karaoke cooldowns)!

A Seamless Experience and a Game-Changer for My Routine

I just got my Peak Shasta sauna and I’m already in love! Delivery was smooth and seamless—it arrived right on time and in perfect condition, which was such a relief. The Peak team was amazing throughout the whole process, super responsive and helpful every step of the way. As a yogi and writer, I was hoping this would become a space to decompress and get inspired, and it absolutely is. I’ve already had a few brainstorm sessions inside and felt the ideas flowing. Plus, the red light therapy is no joke—my rosacea-prone skin is already looking calmer and less inflamed. So grateful I made the leap!

Hi there!

Thank you so much for your kind words about your experience with our Peak Shasta sauna. We are thrilled to hear that it has been a seamless and game-changing addition to your routine. Our team takes pride in providing excellent customer service and we are happy to hear that it made a positive impact on your experience.

Dani M.
Obsessed!!! Best investment I've made in years...

Honestly, I couldn't be happier with my Peak Saunas Shasta! Delivery was super smooth and assembly was a total breeze — I actually put it together solo in about 45 minutes (totally doable, but definitely easier with two people). The design is super sleek and modern, and it's compact enough to fit in my bedroom without feeling cramped. That said, it's still roomy enough for me to kick my feet up and fully relax.

The heat-up time blew me away — it hit 140 degrees in just 10 minutes, and within 20 minutes it was up to 158 and I was SWEATING. The XL red light therapy panel is HUGE — way bigger than I expected in the best way. I’m turning 40 this year and got this mainly for muscle recovery and anti-aging perks—and honestly, it already feels like one of the smartest things I’ve done for myself.

Also, shoutout to the Peak Saunas team — they were so friendly, knowledgeable, and kept me in the loop every step of the way. Even though there was about a month delay (hey, it happens), it was so worth the wait. Hands down one of the best purchases I've made in a long time. If you're on the fence — just go for it!

Wow—thank you for such an incredible review, Dani! We’re absolutely thrilled to hear how much you’re loving your Shasta sauna. From the quick and easy assembly to the powerful heat-up and that XL red light panel—we love that it's already become such a rewarding part of your routine. Turning 40 never looked so good!

And a huge thank you for the kind words about our team—it means the world to us. We know the delay was less than ideal, so we really appreciate your patience and positive attitude. Welcome to the Peak family—we're so glad you made the leap!

Unbelievable Service

The test of a good company is how they perform during adversity. I ordered my Shasta 1-Person Full Spectrum Infrared Sauna with XL Medical-Grade Red Light Therapy & Smart WiFi App Control just before tariffs were imposed which resulted in long delay in shipments. This was beyond their control but they never abandoned me in answering inquires quickly and honestly. Once the unit arrived, the assembly and performance were as advertised. A small issue was resolved with the teams continued help. Their service was above and beyond. Thank you!

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 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.
