The honest infrared bed benefits come down to what gentle, sustained heat does to the body: it relaxes tight muscles, opens up circulation, raises your heart rate a little the way light exercise does, and leaves most people noticeably calmer and sleepier afterwards. What it does not do is flush toxins out through your sweat, burn fat, or replace a workout. At our Plateau and Laval clinics, the infrared bed is paired with full-body red light in a single 45-minute session as part of our red light therapy Montreal program — and as November settles in, it is one of the most requested ways to warm up and unwind. This article focuses on the heat side of that session: what happens in your body minute by minute, which benefits the research genuinely supports, the myths worth dropping, why it suits a Québec winter, who should skip it, and current package pricing.

What this article covers

What does an infrared bed actually do to your body?

An infrared bed delivers radiant heat that is absorbed by your skin and the tissue just beneath it, so you warm up from the outside in without having to sit in very hot air. Your body responds to that heat the same way it responds to any warm environment: blood vessels near the surface widen to release heat, your heart pumps a little faster to move more blood to the skin, and once your temperature climbs far enough, you start to sweat. That chain of responses — not anything special about the light itself — is where nearly all of the benefits of infrared heat come from.

Here is roughly how a 45-minute session unfolds for most first-time clients on our bed.

Nothing in that sequence is invasive or intense. You lie down, stay clothed in light garments or a towel, and the bed does the rest. The red light that runs during the same session works through a different mechanism, which we cover in detail in our guide to what red light therapy does at the cellular level — this article stays with the warmth.

Which infrared bed benefits are actually backed by research?

The research on repeated dry heat is broader than most people expect, but it is uneven. A 2018 systematic review of regular dry sauna bathing — including infrared saunas — found 40 clinical studies with 3,855 participants, yet only 13 were randomized controlled trials and most enrolled fewer than 40 people. The strongest long-term data comes from large Finnish population studies of traditional saunas, not infrared beds specifically. So the fair way to read the evidence is: heat itself has real effects, and an infrared bed delivers heat, but bed-specific trials are small.

That last card matters because infrared marketing often borrows the strongest results from traditional sauna research and attaches them to every heat device on the market. We would rather you book a session for what it reliably delivers — warmth, ease and recovery — and treat everything else as a possible bonus.

Does sweating in an infrared bed detox your body?

No — and this is the claim we hear most often. Sweat is overwhelmingly water with some salt and minerals. Your liver and kidneys are the organs that clear waste and environmental chemicals from the body, and they do it continuously whether you sit in a warm bed or not. Trace amounts of some compounds do appear in sweat, but in quantities far too small to call a “detox”. The healthy reading of a good sweat is simple: your temperature regulation is working, and you need a glass of water.

A few other popular claims deserve the same plain answer.

What does infrared heat do for your skin?

In the short term, heat brings blood to the surface, so skin looks warmer, pinker and a little more radiant for a few hours afterwards. A good sweat followed by a rinse can also leave skin feeling soft and clean. Those are real, pleasant effects — but they are temporary. The longer-term skin benefits people associate with these sessions, such as smoother texture and more even tone, are linked to the red light component rather than the heat.

There are two important caveats. First, heat can dehydrate skin, especially in winter when indoor air is already dry, so moisturize soon after your session. Second, heat is a well-known trigger for rosacea flushing and can aggravate melasma. If you are managing either condition, tell us before booking — we may suggest a shorter, cooler session, a red-light-only approach, or a different treatment through our pigmentation care instead. And if you have had a chemical peel, laser treatment or microneedling in the past week, wait until your skin has fully settled before adding heat.

Why is an infrared bed especially good in a Québec winter?

From November to March, Montrealers spend months braced against the cold — shoulders up, muscles tight, days short and dark by late afternoon. An infrared bed answers that almost perfectly: it is deep, enveloping warmth you can schedule, in a quiet room, without stepping into a 90-degree sauna.

One honest limit: if what you are feeling in winter is persistent low mood, an infrared bed is a pleasant comfort, not a treatment. Seasonal depression deserves a conversation with your doctor — and the bright-light therapy used for it is a different device entirely from the red light in our bed.

How is an infrared bed different from a sauna?

All three formats below deliver heat, and the body’s response to heat is broadly similar across them. The differences are in how intense the air feels, how long you can comfortably stay, and what else comes with the session.

If you already love a Finnish sauna, an infrared bed will feel milder — that is the point. If saunas leave you light-headed or claustrophobic, the bed is usually the format that finally works.

How often should you use an infrared bed?

For most healthy adults, one to three sessions a week is a comfortable, sustainable rhythm. Relaxation is immediate, but the recovery and circulation benefits people value most come from regularity, so a short series works better than a single visit. This is how the experience typically builds over a package.

Two practical rules make every session better: drink a glass or two of water beforehand and again afterwards, and avoid alcohol and heavy meals right before. Get up slowly at the end, because blood pressure can dip briefly when you stand after lying in the heat.

Who should not use an infrared bed?

Heat is gentle for most people, but it does put a real load on the heart and fluid balance. These are the situations where we will ask you to wait or to check with your doctor first.

If any of these apply, it does not necessarily mean never — it means a conversation first. That screening is part of every booking.

What makes an infrared bed session at IPL Lab different?

Plenty of gyms and wellness studios now have a heat device in a back room. What we focus on is everything around the heat.

And we will always be straight with you about what heat can and cannot do. If a different treatment would serve your goal better, we will say so.
