Infrared Sauna
Infrared Sauna vs Red Light Therapy Beds: A Canadian Buyer's Guide
An infrared sauna heats your body until you sweat; a red light therapy bed bathes you in light with almost no heat. That single difference decides everything else. Saunas raise your core temperature a few degrees, push your heart rate to 100–150 bpm, and work the whole body at once. Beds use red light at 630–660 nm and near-infrared at 810–880 nm to act directly on skin and cells. For most Canadian homes the smartest buy is not the bed at all: a red light panel plus an infrared sauna delivers the same range of benefits for a fraction of a bed's C$4,999–C$25,000+ price.
Key Takeaways
- Heat vs light: an infrared sauna makes you sweat and conditions your cardiovascular system; a red light bed produces almost no heat and works at the cellular level.
- Wavelengths differ by orders of magnitude: saunas emit far-infrared at 5,600–10,000 nm, while red light beds use 630–880 nm for photobiomodulation.
- Cost gap is large: full-body red light beds run C$4,999–C$8,000 and capsules reach C$25,000+, versus roughly C$2,000–C$5,000 for a home infrared sauna and far less for a panel.
- A panel usually beats a bed for home value — you can reposition it to treat your face, back or knee, so most people never need the bed.
- Pick by goal: skin and targeted pain lean red light; relaxation, sweating and winter cardio conditioning lean infrared sauna. Explore the full range in the Calore sauna collection.
- You can run both: many people combine 2–3 sauna sessions with 4–6 red light sessions each week.
Heat and sweat vs light only: the core difference
The defining difference is heat. An infrared sauna deliberately warms your body until you sweat, while a red light therapy bed delivers light with almost no temperature change. Everything else — session length, benefits, cost, who it suits — flows from that.
Both technologies use energy from the electromagnetic spectrum, but at very different wavelengths and with very different targets. A sauna's far-infrared energy is absorbed near the skin and converted to heat, raising your core temperature and triggering a whole-body stress response. A red light bed's much shorter wavelengths pass into tissue and are absorbed by structures inside your cells, prompting a repair response without a meaningful rise in temperature. One is a heat therapy; the other is a light therapy.
What is an infrared sauna and how does it work?
An infrared sauna is a heat cabin that uses infrared emitters to warm your body directly rather than heating the surrounding air. Instead of the fierce steam heat of a traditional sauna, it runs at a gentler 45–60°C (113–140°F) while still producing a deep sweat.
The emitters put out far-infrared energy in roughly the 5,600–10,000 nm range. That energy is absorbed at the skin and converted to heat, raising both skin and core temperature by a few degrees. Your body responds the way it would to moderate exercise: blood vessels dilate, circulation increases, sweating ramps up to regulate temperature, and heart rate climbs to 100–150 bpm. Regular heat exposure also upregulates heat shock proteins, which support cellular resilience. Sessions typically last 20–40 minutes, two to four times a week.
Stat: A landmark Finnish population study following more than 2,000 men for over 20 years linked frequent sauna bathing (4–7 sessions weekly) to lower cardiovascular and all-cause mortality (PMC, JAMA Internal Medicine analysis). Infrared saunas produce a similar physiological response through gentler heat. Calore's indoor infrared sauna is built for exactly this kind of consistent, year-round ritual.
What is a red light therapy bed and how does it work?
A red light therapy bed is a horizontal, full-body device lined with LED arrays that bathe you in red and near-infrared light while you lie down — think of a light-emitting version of a tanning bed, but without UV and without heat. It delivers therapeutic light hands-free across your entire body in a single session.
The LEDs emit red light at 630–660 nm and near-infrared light at 810–880 nm. These wavelengths fall inside the body's "optical window," so they penetrate skin and tissue rather than simply heating the surface. The mechanism is photobiomodulation: light photons are absorbed by cytochrome c oxidase inside your mitochondria, which increases ATP (cellular energy) production, releases nitric oxide to improve local blood flow, and switches on genes involved in collagen production and tissue repair. Because there is no significant heat, sessions are short — usually 10–20 minutes — and can be done as often as daily.
Penetration depth, plainly: red light (630–660 nm) reaches a few millimetres, ideal for skin and superficial healing. Near-infrared (810–880 nm) reaches up to several centimetres, useful for muscle, joint and nerve tissue. Far-infrared sauna energy (5,600–10,000 nm) is absorbed superficially and works through systemic heat rather than depth.
Benefits of each: where they help
Both reduce pain and inflammation, but they get there by different routes — heat and circulation for the sauna, direct cellular signalling for red light. Here is where each genuinely shines.
Where an infrared sauna leads
Saunas excel at whole-body outcomes. The heat relaxes tense muscles, boosts circulation to aching joints, and triggers an endorphin release that dulls pain and lifts mood. The cardiovascular effect is real: an elevated heart rate mimics light exercise, and regular use is associated with improved vascular function and modest reductions in blood pressure. Heavy sweating and the meditative wind-down also make saunas a favourite for relaxation and better sleep — and in a Canadian winter, a warm cabin gets far more use than any cool-light device.
Where a red light therapy bed leads
Red light is the precision tool. Its wavelengths stimulate fibroblasts to produce more collagen and elastin, with controlled trials showing measurable improvements in wrinkle depth, skin roughness and tone after 8–12 weeks. It is also strong for targeted recovery: meta-analyses of photobiomodulation for knee osteoarthritis report clinically meaningful pain reductions, often in the 20–40% range (PMC review of photobiomodulation for knee osteoarthritis). Because it produces no heat, it also suits people who cannot tolerate a sauna.
Which one for your goal?
Match the tool to the outcome you actually want. If your goal is skin, use light; if it is sweating, relaxation and cardio conditioning, use heat.
- Skin, collagen, fine lines, acne or scars: a red light therapy bed or panel, because those wavelengths act directly on skin cells.
- Localized joint, tendon or nerve pain: red light, because you can target a specific area with the right dose.
- Whole-body relaxation, deep sweating and stress relief: an infrared sauna, which loads the entire body at once.
- Cardiovascular conditioning and winter wellness: an infrared sauna, for the exercise-like heat response.
- Heat-sensitive or a medical reason to avoid heat: red light, which barely raises body temperature.
Cost, space and running expense in Canada
On upfront price, an infrared sauna is usually the cheaper full-body device, and a red light panel is cheaper still than a red light bed. Full-body red light therapy beds typically run C$4,999–C$8,000, and spa-grade 360-degree LED capsules climb to C$8,000–C$25,000+. A home infrared sauna generally lands around C$2,000–C$5,000, while a quality full-body panel costs far less again.
Running costs favour red light. An infrared sauna draws roughly 1.5–3 kW and costs a bit more per session, while red light devices draw about 300–1,200 W. Actual electricity cost varies by province, so treat these as directional rather than exact. On space, a red light bed needs floor room to lie down, a sauna needs a cabin footprint and adequate electrical service (larger units may need a dedicated circuit), and a panel simply mounts on a wall or stand — the smallest footprint of the three.
Red light bed vs red light panel: why the panel usually wins
If you have decided you want red light, a panel is the better buy for most homes — the bed's main advantage is hands-free convenience, and you pay a lot for it. A full-body bed costs several times more than a comparable panel while adding relatively modest benefit.
A panel earns its keep because you can reposition it: hold it to your face for skin, drop it to a knee for joint pain, or aim it at your lower back — treating each area in sequence with the right dose. A bed treats everything at once and looks impressive, which is why clinics and spas invest in them, but for one household that convenience rarely justifies the price gap. This is why we do not stock red light beds; a Calore red light therapy panel gives you the same wavelengths and flexible targeting for a fraction of a bed's cost. If you want the same comparison against a red light sauna setup, see our guide on red light therapy vs infrared saunas.
Can you get both?
Yes, and for many people the pairing is the ideal setup. The two therapies are complementary: the sauna handles heat, sweat and cardiovascular conditioning, while red light handles skin and targeted repair.
A typical weekly rhythm is 2–3 infrared sauna sessions — often after a workout or as an evening wind-down — alongside 4–6 shorter red light sessions for skin, joints or recovery. Some people run red light immediately after a sauna to take advantage of the increased circulation; others separate them by a few hours to avoid overstimulation. Crucially, a panel-plus-sauna combination usually costs less than a single high-end red light bed while covering a wider range of goals.

Safety: eyes, heat and who should be cautious
Both therapies are well tolerated by healthy adults, but each has its own precautions — heat for the sauna, bright light for the bed.
Red light beds — protect your eyes. Bright LED arrays should not be stared into, and most beds and panels include goggles — use them, especially near the face. Photosensitizing medications and active skin cancer in the treatment area warrant caution and a conversation with your doctor first.
Infrared saunas — respect the heat. Check with a healthcare provider before regular use if you have cardiovascular disease, unstable or uncontrolled blood pressure, are pregnant (particularly the first trimester), or take medications that impair sweating or heat tolerance. Stay hydrated, start with shorter sessions, and step out if you feel unwell.
For either device: hydrate, follow the manufacturer's instructions, and build up gradually rather than starting at maximum duration.
5 steps to choosing the right device
- Name your primary goal. Skin and targeted pain point to red light; sweating, relaxation and cardio point to an infrared sauna.
- Check your heat tolerance and health. If heat is off the table medically, red light is your route.
- Measure your space and power. A sauna needs a cabin and possibly a dedicated circuit; a panel needs almost nothing; a bed needs floor room.
- Set a realistic budget. Compare a panel-plus-sauna setup against a single red light bed — the combo is usually cheaper and covers more goals.
- Decide bed or panel for red light. Unless you need hands-free full-body coverage every day, choose a panel and put the savings toward a sauna.
The Calore Verdict
Infrared saunas and red light therapy beds solve different problems: one uses heat and sweat to condition the whole body, the other uses light to repair skin and target specific tissue. The red light bed is the expensive way to get light — a repositionable panel delivers the same wavelengths for far less, which is why we recommend a panel over a bed for the home.
Key finding: for most Canadians, the best-value setup is not a red light therapy bed at all — it is a red light panel paired with an indoor infrared sauna, which together cover skin, recovery, relaxation and winter cardio for less than a single high-end bed.
Frequently Asked Questions
What is better, an infrared sauna or a red light therapy bed?
Neither wins outright, because they do different jobs. An infrared sauna uses heat and sweat for whole-body relaxation, circulation and cardiovascular conditioning, while a red light therapy bed uses red and near-infrared light for skin, collagen and targeted recovery without heat. For most Canadian homes, a red light panel plus an infrared sauna delivers the same benefits as a bed for far less money, since full-body beds run C$4,999 to C$25,000 or more.
Is an infrared sauna as good as a red light therapy bed?
For heat-based benefits like sweating, circulation and cardiovascular conditioning, an infrared sauna is better, because a red light bed produces almost no heat. For skin rejuvenation, collagen production and targeted joint pain, the red light bed is better, because those wavelengths act directly on cells. They are complementary tools rather than substitutes.
Can you use an infrared sauna and red light therapy at the same time?
Yes. For healthy adults it is generally safe to combine them, and many people run 2 to 3 infrared sauna sessions a week for heat benefits alongside 4 to 6 shorter red light sessions for skin and recovery. Some people prefer red light immediately after a sauna to take advantage of increased circulation. Start slowly, stay hydrated, and check with your doctor first if you have any medical conditions.
Do I need a red light therapy bed, or is a panel enough?
For most home users a panel is enough. A full-body red light bed costs several times more than a quality panel while adding relatively modest benefit, because you can reposition a panel to treat your face, back, knee or shoulder in sequence. A red light bed mainly buys convenience and hands-free full-body coverage. Unless you run a clinic or spa, a panel plus an infrared sauna is usually the better-value setup.
How much does a red light therapy bed cost compared to an infrared sauna?
Full-body home red light therapy beds typically run C$4,999 to C$8,000, and spa-grade 360-degree LED capsules reach C$8,000 to C$25,000 or more. A home infrared sauna generally costs about C$2,000 to C$5,000, and a quality full-body red light panel is far less again. Infrared saunas also cost a little more to run per session because they draw 1.5 to 3 kW versus roughly 300 to 1,200 W for red light.
Do you need eye protection for a red light therapy bed?
You should protect your eyes during any red light or near-infrared session near the face, and most beds and panels ship with goggles. Bright LED arrays can be uncomfortable and photosensitizing medications increase the risk, so goggles are a sensible precaution. Infrared saunas do not require goggles, but you should still avoid staring at any visible light element and keep sessions within recommended limits.
