Whole-body Photobiomodulation.

Reviewed by our clinical team · Longevity Gyms · Updated 2026

Red and near infrared light in the 600 to 1100 nanometre range is absorbed by an enzyme inside your mitochondria. That absorption is measurable, well characterised, and the reason this modality exists.

  • Delivered across the full body rather than to one area at a time
  • Non ionising and non thermal. It does not burn or tan
  • Entirely passive. Stand or lie still for the duration
  • One of the better evidenced modalities in the facility

What It Is

Light your cells can actually use.

Not all light does the same thing. Ultraviolet damages DNA at high doses. Red and near infrared light, roughly 630 to 850 nanometres, is non ionising. It passes into tissue without generating meaningful heat and interacts with cells biochemically rather than thermally.

Most photobiomodulation is delivered to one area with a panel or a handheld device. Ours is whole body, which changes the exposure rather than the mechanism. You stand or lie still, the array runs, and nothing touches you.

How It Works

One enzyme does most of the work.

This is one of the few modalities in the facility where the mechanism is understood down to the specific molecule involved, which is why we can describe it plainly rather than gesturing at it.

Light Reaches Tissue

Step one · penetration

Red and near infrared wavelengths pass through skin without being absorbed by water or haemoglobin the way other wavelengths are. This is why this particular band is used rather than visible light more broadly.

  • Non ionising, unlike ultraviolet
  • Non thermal at therapeutic doses
  • Penetration depth varies with wavelength

Cytochrome c Oxidase Absorbs It

Step two · the target

A protein in the mitochondrial membrane called cytochrome c oxidase absorbs these wavelengths. It sits at the end of the electron transport chain, the process that produces ATP. This is the specific molecular interaction the field is built on.

  • A named enzyme, not a vague cellular effect
  • Positioned at the end of the electron transport chain
  • Absorption spectrum matches the wavelengths used

ATP Production Responds

Step three · the output

Absorption is associated in the literature with acceleration of the electron transport chain and increased ATP production. ATP is what every cell spends to do its work, which is why this modality sits in the Cellular Energy system rather than in Recovery.

  • ATP is the cell's energy currency
  • Studied alongside effects on inflammation
  • Research also examines mitochondrial dynamics

Dose Follows A Curve

Step four · the constraint

Photobiomodulation follows a biphasic dose response. Too little produces no effect and too much can reduce the benefit rather than increase it. Longer sessions are not better sessions, which is why duration is set rather than chosen.

  • A biphasic curve, not a linear one
  • Wavelength, irradiance, and duration all matter
  • Protocol set by our team, not by preference
The Mechanism

What is established.

Photobiomodulation has moved from experimental into accepted clinical practice for several specific indications, and it is worth being precise about which parts have that standing.

01

The molecular mechanism is well characterised

That red and near infrared light is absorbed by cytochrome c oxidase, and that this relates to mitochondrial respiratory chain activity and ATP production, is described consistently across the literature. This is not a proposed mechanism, it is the accepted basis of the field.

02

Some clinical applications are established practice

Photobiomodulation has been included in clinical treatment guidelines for oral mucositis since 2020, one of the clearer signals that a therapy has moved beyond experimental status. A 2025 consensus review also addressed applications including peripheral neuropathy and chronic ulcers.

03

Whole body delivery has a smaller evidence base than local

Most published research studies photobiomodulation applied to a specific area. A 2025 systematic review looking specifically at whole body delivery for exercise performance and recovery found only five eligible studies from 193 screened, covering 105 participants. The mechanism is the same. The volume of whole body specific evidence is smaller, and we would rather tell you that than let it pass.

Ideal For

Who tends to use it.

One of the most broadly tolerated modalities we operate, which makes it easy to include consistently.

Athletes using it around training, before or after depending on the goal

Members working on the Cellular Energy system alongside other passive modalities

People with little time, since sessions are among the shortest here

Anyone who cannot tolerate exertion, heat, cold, or pressure based modalities

People who want a modality where the mechanism is genuinely well described

Screening applies for photosensitising medication, pregnancy, and certain conditions

Your Session

What to expect.

Short, simple, and among the easiest sessions in the building to keep consistent.

01
Before

Preparation

  • Clean skin without lotion, oil, or sunscreen, which can block the light
  • More exposed skin means more surface area receiving light
  • Tell our team about any photosensitising medication
  • Eye protection is provided and worn throughout
02
During

The Session

  • You stand or lie within the array while it runs
  • Ten to twenty minutes depending on your protocol
  • You may feel mild warmth, though it is not a heat treatment
  • Nothing touches you and nothing is applied to the skin
03
After

Afterwards

  • No recovery period and no after effects to plan around
  • Train, drive, or return to work immediately
  • Frequently paired with another passive session in the same visit
  • Consistency matters more here than any individual session

What It May Support

Framed as mechanisms, not promises.

Each item describes what this modality is studied in relation to. None is a guaranteed outcome, and individual response varies.

01

Absorption by cytochrome c oxidase in the mitochondrial membrane, a well characterised interaction

02

Activation of the mitochondrial respiratory electron transport chain

03

Increased ATP production, the energy currency every cell spends

04

Studied in relation to inflammatory response at the cellular level

05

Examined in the literature for tissue repair and wound healing

06

Research into effects on mitochondrial fusion and fission dynamics

07

Whole body delivery studied for exercise performance and recovery

08

Non thermal and non ionising, distinguishing it from ultraviolet exposure

How It Fits Your Protocol

Consistency over intensity.

Because the dose response is biphasic, this is a modality where doing it regularly at the right dose beats doing it occasionally for longer.

Step One

We measure where you are

VO₂ Max and InBody establish your baseline, and your consultation establishes what you are trying to change. Protocol decisions follow from that.

Step Two

We set the dose

Duration and frequency are set deliberately rather than left open. More is not better here, and the biphasic curve is the reason your session length is fixed.

Step Three

We retest

Your markers are measured again at a defined point. What continues or changes is decided on data rather than on how a session felt.

The Science Behind It

A mechanism you can name.

Photobiomodulation is among the better evidenced modalities we operate. These are papers on the mechanism and its clinical application, linked so you can read the source.

Photobiomodulation uses non thermal red or near infrared light in the 600 to 1100 nanometre range. That spectrum is pertinent to mitochondrial light absorption, activating the respiratory electron transport chain and increasing ATP production.

Mitochondria2025

Does photobiomodulation alter mitochondrial dynamics?

Examines whether red and near infrared light influences mitochondrial fusion and fission, the processes by which mitochondria continually reshape themselves. Relevant because dysfunctional mitochondria limit energy production and raise reactive oxygen species.

How To Read These

Strong mechanism, and one honest distinction

The molecular mechanism here is well characterised and several clinical applications have entered accepted practice. One thing worth carrying as you read: most of that evidence examines light applied to a specific area rather than across the whole body. The first paper above looks specifically at whole body delivery and found a small number of eligible studies. The mechanism is identical. The volume of whole body specific research is smaller, and you should weigh that yourself.

Frequently Asked

Questions answered.

Is this the same as a tanning bed?

No, and the difference matters. Tanning beds emit ultraviolet, which is ionising and damages DNA at high doses. This uses red and near infrared, which is non ionising and non thermal. It will not tan you, burn you, or affect your skin the way UV does.

Will I feel anything?

Mild warmth, sometimes. It is not a heat treatment and the sensation is not the mechanism. As with the rest of this category, we would be cautious of judging a session by how it felt.

Is longer better?

No, and this is the most misunderstood thing about the modality. Photobiomodulation follows a biphasic dose response, meaning too much can reduce the effect rather than increase it. Your session length is set for that reason.

How is this different from the panel I could buy?

Coverage and dose control, mainly. A home panel treats one area at a time at whatever output it happens to deliver. Whole body delivery covers far more surface area at a specified irradiance and duration. If you already own a panel and use it consistently, tell us and we will factor that in rather than duplicate it.

Do I need to undress?

Light only affects skin it reaches. More exposed skin means more surface area treated, so most people wear minimal clothing. That is your choice and the session works either way, just over less area.

Should I use it before or after training?

It depends on what you are after, and the research examines both. Our team sequences it deliberately within your protocol rather than leaving the timing to chance.

Is it safe?

It is non ionising, non thermal, and among the best tolerated modalities we operate. Eye protection is worn throughout. Screening applies for photosensitising medications, certain skin conditions, and pregnancy.

How often should I use it?

Where prescribed, typically three to five times a week. Sessions are short enough to include regularly, and consistency matters considerably more here than any single visit.

Is it included in membership?

Access depends on your tier. Circuits are the unit of membership, and which modalities appear in yours is set by your protocol rather than chosen from a menu.

The First Step

Reserve Your Consultation.

Your protocol starts with a conversation and a baseline, not with a modality. In it we will:

  • Understand what you are actually trying to change
  • Screen for photosensitising medication or anything else relevant
  • Set the dose and frequency deliberately rather than leaving it open
  • Explain honestly where it helps and where it does not
  • Build a protocol across the systems that matter for you
