Why red light therapy doesn't belong in a Pilates class (and what actually works instead)

If you have taken a Reformer Pilates class under a red light panel and wondered whether it is actually doing anything for you, the honest answer is: probably not much. Not because red light therapy does not work. It is genuinely useful. But a panel glowing on the studio wall while you move through a flow cannot deliver what a proper red light therapy session is built to deliver, and it was never designed to.

That is not a knock on your Pilates class. Reformer Pilates does what it does, controlled resistance, alignment, core control, coached movement, and it does it well on its own terms. Red light therapy does something completely different, and it needs conditions a moving class simply does not have. Blending the two under one red glow does not combine their benefits. It just means neither one is getting a fair shot.

Why is red light suddenly showing up in Pilates studios?

Red light panels have become a popular addition to boutique fitness spaces over the last couple of years, often installed as ambient studio lighting rather than as a piece of therapeutic equipment with its own protocol. It looks calming, it photographs well, and it fits the general wellness aesthetic a lot of studios are going for. None of that is dishonest exactly, but it does blur a line worth being clear about: a red bulb in the room is different from a dosed red light therapy session.

If a studio near you has one, it is not doing you any harm sitting there while you train. The question is just whether it is giving you what red light therapy actually promises, and for most setups it is not, for reasons that come down to how this kind of light needs to be delivered.

What does red light therapy actually need to work?

Red light therapy, more precisely called photobiomodulation, works by exposing your skin and the tissue beneath it to specific wavelengths of red and near-infrared light, which cells absorb and use to support processes like circulation, tissue repair and inflammation. That much is genuinely well established. The part that gets skipped over in most marketing is that it only works within a fairly specific set of conditions.

The first is dose. Photobiomodulation follows what researchers call a biphasic dose-response, meaning the relationship between how much light and how much benefit is not a straight line where more is always better. According to a review by Huang, Sharma, Carroll and Hamblin published in Dose-Response, low doses of light can have little to no effect, moderate doses produce the biggest benefit, and doses pushed too high can start working against you, reducing or reversing the effect entirely.¹ That pattern shows up consistently across cell studies and animal experiments, which is part of why some clinical trials of red light therapy have come back disappointing. They simply were not dosing it right. A separate review of the wider evidence base by Zein, Selting and Hamblin, published in the Journal of Biomedical Optics, found published protocols cluster around 4 to 10 joules of light energy per square centimetre of tissue, with some going up to 50 J/cm² at the skin surface, and that ineffective results were put down to over-dosing about as often as under-dosing.² There is still no one universally agreed number, but there is broad agreement that the number matters.

The second is distance. Light intensity falls off sharply the further you are from its source, which is basic physics, not a red light therapy quirk. Standing several feet from a wall-mounted panel receives a fraction of the light you would get lying directly beneath or beside one. Move around during a class, and that distance is constantly changing too.

The third is time. Getting a therapeutic dose is not just about having the light on, it is about your skin being exposed to the right amount for long enough, consistently, in one sitting. A class built around movement, instruction and changing positions was never designed around that requirement, because it is not trying to be.

Why does a panel on the studio wall not meet any of that?

Put those three requirements next to a typical Pilates studio red light panel and the mismatch is fairly obvious. You are not a fixed distance from it, you are moving through a flow. The exposure time is not set by what your tissue needs, it is set by however long the class happens to run. And critically, most red light panels sold into studios and gyms are general wellness products, not certified medical devices built and tested to deliver a specific, verifiable dose. There is often no way to know what dose, if any, you are actually receiving.

None of that makes the panel dangerous. It just means it is very unlikely to be doing the specific cellular job red light therapy is supposed to do, while you are also trying to hold a plank or thread the needle. It is ambient lighting wearing the branding of a treatment.

What does a proper red light therapy session actually look like?

At Hanbury Health, medical-grade red light therapy runs on a CE-marked medical device rather than a decorative panel. It uses red light (around 630nm) and near-infrared light (around 940nm), alongside a blue wavelength (around 470nm), delivering a measured dose across the whole body at once, engineered within a 3 to 15 J/cm² range that sits inside the parameters the underlying research supports, rather than an amount nobody has checked.³ It is LED-based, heat-free, with no UV involved.

The session is built around the conditions red light therapy actually needs: you are close to the light and staying still for the whole thing, so the dose you are getting is consistent and known, not incidental to whatever else is happening in the room. It is booked and run as its own thing, not layered underneath another activity, and it sits in the recovery suite at Hanbury Health alongside cryotherapy, compression therapy and the Shiftwave chair.

So is red light in a Pilates studio completely pointless?

As ambient lighting, it is fine. Nobody needs to switch it off out of concern for their safety. The issue is expectation. If you are going to a class partly because there is a red light panel in the room, it is worth knowing you are very unlikely to be getting a measurable red light therapy dose from it, in the same way a massage chair left switched off in the corner would not give you a massage.

The fix is not to give up on either one. It is to stop expecting one to quietly do the other's job.

Where does Reformer Pilates actually fit in?

This is the part that is easy to lose in the red light conversation: Reformer Pilates does not need to borrow credibility from a light panel. What it is built to do, working through controlled resistance on the reformer's springs, building genuine core and postural control, correcting movement patterns with proper coaching, is valuable on its own, evidenced on its own, and worth turning up for on its own. If you are new to it, start with what reformer Pilates actually is and how the machine works, or whether reformer Pilates is good for beginners. If your reason for coming is a sore back, read how reformer Pilates is used for back pain.

If anything, separating the two makes each one better. You get full attention on your form and breathing during your class, without a light doing double duty in the background. And if you also want red light therapy, you get a session actually built to deliver it, rather than a watered-down version squeezed in around your workout.

Where can you do both properly in Milton Keynes?

Hanbury Health is the only place in Milton Keynes bringing coached Reformer Pilates and a CE-marked medical-grade red light therapy bed together under one team of experts, kept as two distinct things rather than one blended into the other. Reformer classes run through the Reformer Pilates and Yoga programme, and the medical-grade red light therapy bed sits in the recovery suite, bookable on its own.

Why is Hanbury Health different?

Most places that add a red light panel to a studio are trying to make one thing feel like two. At Hanbury Health, you actually get two things, done properly, by people who know the difference between ambient lighting and a dosed treatment, because they run both.

That matters beyond just getting your money's worth. Because Reformer Pilates, physiotherapy and the recovery suite sit inside the same team, if something comes up in a class, a pattern in how you are moving, a niggle that keeps returning, it does not just stay a passing comment. It can be picked up and looked at properly by experts who already understand your training, rather than you having to explain yourself again somewhere new. You are not choosing between a good workout and genuine recovery support. You get both, kept honest about what each one actually is.

Two different things, both worth doing properly

A red light panel in your Pilates class is not hurting you, it is just not doing what a real red light therapy session does. At Hanbury Health you can have both: coached Reformer Pilates for movement and strength, and a CE-marked medical-grade red light therapy bed for a dose that is actually measured, kept as two separate things so each one delivers what it is supposed to.
