Red Light Therapy in Gyms and Spas: What Women Need to Know

With growing buzz around red light therapy (RLT) and photobiomodulation (PBM) for fertility, hormone health, and full-body vitality, more women are exploring everything from spa wellness pods to in-gym red light booths and home-use panels. Some centers offer very attractive subscription models - but do they deliver?

Not all “red light” is created equal. Here’s an expert guide to help you discern what really works, what’s just for surface beauty, and what you need to ask before investing your time and hopes.

Commercial Wellness Pods: The Cocoon Wellness Pod

Cocoon Wellness Pod is a commercial-grade device found in spas, medispas, and wellness centers. Its features include:

·       Chromolight modules with red (~630–660 nm, not precisely specified) and blue light (around 470 nm), plus full-spectrum infrared (far, mid, near) for a warming, dry-heat sauna effect.

·       Other modalities: Vibration massage, aromatherapy, Himalayan salt illumination, and even exercise bands for in-pod use.

·       Light delivery: You recline on a cushioned bed, with red/blue LEDs positioned above and to the sides (not underneath you). The light source is several inches to approximately 1 foot from your body, and your head is outside the pod.

·       Intended use: Marketed as a relaxation, wellness, and recovery experience. No specific medical claims.

Cautions:

·       Wavelength and Irradiance: No technical specs available.

·       Surface-level results: Without NIR and with unspecified irradiance, these pods are most likely to deliver benefits to the skin (glow, tone, relaxation), with little or no impact on deeper organs like ovaries or uterus.

·       Blue Light Caution: Many pods use blue chromotherapy as well, which is not safe or evidence-based for whole-body or fertility use and can increase oxidative stress if used extensively over the full body.

Important Note: Cocoon Wellness Pod Specs and Fertility

The Cocoon Wellness Pod is marketed as a relaxing, full-body experience offering chromolight (red and blue) and infrared heat, there is a significant lack of transparency about its technical specifications. The manufacturer doesn’t provide clear information on the exact wavelengths (nm), the presence of true near-infrared (NIR) LEDs, or the power output (irradiance, mW/cm²) delivered to the body. These details are crucial for achieving the depth and biological effectiveness required for fertility support or deeper tissue photobiomodulation.

Without published specs, it’s impossible to confirm whether the Cocoon Pod can deliver light strong enough, and at the appropriate wavelengths, to affect ovarian or reproductive health. Surface-level red or blue light exposure may give your skin a healthy glow or create a relaxing spa experience, but won’t reach or benefit deeper tissues such as the ovaries, uterus, or endocrine system. For women seeking fertility benefits, it’s far better to look for clinically validated PBM devices with transparent specs, especially those that include NIR light at meaningful power settings.

Any device manufacturer who don’t/won’t include specific specs on their devices is not being transparent.

Distance from the light = less energy delivered to deep tissue/inner organs.

Planet Fitness “Total Body Enhancement” Booth

Many women encounter the Planet Fitness stand-up red light booths (also “Beauty Angel RVT30”) in gyms, drawn in by promises of body and skin benefits:

·       Wavelength: Only visible red light (620 - 700 nm). No NIR!

·       Irradiance: About 13–15 mW/cm² at the skin. Each session lasts 12 minutes (Most of the energy is NOT absorbed into your body due to lack of skin contact).

·       Exposure: You stand inside a large booth, surrounded by vertical LED panels and vibration plates for circulation.

·       Claims: Marketed for skin beauty, circulation, and post-workout recovery.

·       Limitations: No deep tissue or organ-level benefits, no NIR and low irradiance means the light penetrates only a few millimeters. Due to the distance from the skin most of that light bounces off so you’re getting very little energy delivered into the body.

Wellness Centers Offering 2 Vertical Panels

As red light therapy centers pop up everywhere some of these offer the experience of standing between two LED panels…but again many don’t list any kinds of specs (and not to sound like a broken record - skin contact matters).

Questions Every Woman Should Ask Before Red Light Therapy - (Don’t be too surprised if you get a blank stare to these questions…)

·       Does this device offer both red and near-infrared light in therapeutic wavelengths?

·       What is the irradiance/power density (mW/cm²) at the skin? (Your skin type will also impact how much light the deeper tissues will absorb).

·       Is there blue light (not recommended for full-body use)? Can it be turned off?

·       Am I being promised results, like deeper tissue or fertility benefits, that the device cannot deliver due to its lack of NIR or low power?

·       Can the provider or facility furnish technical specs and research to support their claims?

If you’re looking for more than glowing skin you need to ask the right questions: many wellness pods, spa beds, and in-gym red light booths deliver for superficial skin treatments but lack the specs required for true photobiomodulation of deep tissues. Always ask for clear wavelength and power information, especially if your goal is hormonal or reproductive support.

Another crucial consideration is the level of expertise - or lack thereof - among staff in most gyms, salons, and wellness spas offering red light therapy. Often, staff are not medically trained, and may have minimal understanding of the science, protocols, or safety guidelines behind effective photobiomodulation. This makes it even more important for women to advocate for themselves, ask about device specifications, and monitor their own sessions. If you do have access to a professional-grade bed or pod (similar to a sunbed) that provides both adequate irradiance and true near-infrared (NIR) wavelengths, make sure to flip over halfway through your session so that both your front and back, and especially your abdomen, are exposed directly to the LED panels. This helps maximize the chance that the therapeutic light reaches deeper pelvic and reproductive tissues, rather than just offering superficial skin-level benefits.
