PEAKFIT Studio in Arden, NC offers 30-minute red light sessions starting at $45
Sessions are most effective when scheduled within 60 minutes after strength training

Red light therapy gets dismissed as a wellness trend by people who haven’t read the research. Athletes and trainers who have read it are quietly booking sessions between workouts. Here’s what the science actually says — and why PEAKFIT brought this technology to Arden, NC as part of our recovery and wellness services.

What Red Light Therapy Actually Does

Red light therapy — also called photobiomodulation — exposes your body to specific wavelengths of low-level light, typically in the 630 to 850 nanometer range. At these wavelengths, light penetrates skin and underlying tissue and is absorbed by mitochondria, the energy-producing organelles inside your cells.

The result is an increase in ATP (adenosine triphosphate) production — the cellular fuel that powers muscle contraction, tissue repair, and virtually every biological process in your body. More ATP means cells can do their repair work faster and more efficiently after the stress of exercise.

This is not a heat treatment. The light produces no significant warmth. It’s a cellular stimulus, not a thermal one. That’s why red light therapy and infrared sauna complement each other — they work through entirely different mechanisms and target different aspects of recovery.

What the Research Shows

A 2016 meta-analysis in Photomedicine and Laser Surgery analyzed 11 randomized controlled trials involving athletes and physically active adults. The authors found that pre- and post-exercise red light therapy significantly reduced muscle soreness and improved recovery markers, including creatine kinase levels (a marker of muscle damage), compared to placebo controls (Photomedicine and Laser Surgery, 2016).

A 2014 study published in the Journal of Athletic Training found that red light therapy reduced DOMS scores by an average of 55% in subjects who received post-exercise treatment compared to those who received a sham treatment (Journal of Athletic Training, 2014).

Beyond soreness, research in journals including Lasers in Medical Science and Photobiomodulation, Photomedicine, and Laser Surgery has demonstrated effects on:

Joint inflammation reduction in people with osteoarthritis
Tendon and ligament healing after acute injury
Skin collagen production and texture improvement
Mood and circadian rhythm regulation with consistent morning use

According to a 2019 review in the Journal of Inflammation Research, photobiomodulation consistently reduced pro-inflammatory cytokines in musculoskeletal tissue across multiple study populations (Journal of Inflammation Research, 2019).

Who Uses Red Light Therapy at PEAKFIT — and Why

Strength training clients use red light post-workout to reduce the inflammatory response and speed up the repair cycle between sessions. This is especially valuable for clients training three or more times per week, where recovery time between sessions is compressed. Our private personal training clients often add red light sessions on the same day as their training appointment.

Adults over 50 find red light therapy particularly useful for joint health. As connective tissue becomes less resilient with age, the anti-inflammatory effects of red light become more relevant. Our senior fitness programs incorporate red light therapy as part of a comprehensive recovery strategy.

Women going through perimenopause and menopause use it for both recovery and the well-documented skin benefits — improved collagen production and reduction in fine lines with consistent use over several months. Our women’s fitness programs address the full picture of what aging well looks like.

Athletes in competition prep and anyone in a high-training-volume block use red light to manage the inflammation load that comes with intensive training. PEAKFIT’s sports performance clients use it strategically around hard training days.

People managing chronic joint pain or arthritis use it as part of an ongoing maintenance strategy. Our specialized programs for chronic conditions pair red light with low-impact training and assisted stretching for a multi-angle approach to pain management.

How a Red Light Therapy Session at PEAKFIT Works

You’ll be positioned close to the panel — typically about 6 to 12 inches from the light source — for 30 minutes. The light is bright but not painful. Many clients close their eyes and use the time to decompress. Some listen to music or a podcast.

You don’t need to remove clothing, though more skin exposure increases the surface area receiving treatment. Most clients wear athletic shorts and a sports bra or tank top.

Sessions are relaxed and require nothing from you except showing up. After your session, you can head straight to the juice bar or your next appointment. There’s no recovery time and no side effects in healthy adults

Pricing is $45 for a single 30-minute session. A 3-session package is available at $115. View our complete programs and pricing page for current package options.

Red Light Therapy vs. Infrared Sauna: Which Should You Use?

This is the most common question we get about recovery services. The short answer: they’re not competing — they’re complementary.

Infrared sauna uses heat to increase circulation, reduce soreness, and trigger systemic relaxation. Red light therapy uses light to stimulate cellular repair at the mitochondrial level and reduce local inflammation. The two work through different mechanisms and produce different recovery effects.

Many PEAKFIT clients use both in the same visit — red light therapy immediately after training, followed by a 30-minute infrared sauna session. This combination gives you the cellular recovery stimulus of red light alongside the circulation and soreness reduction benefits of heat.

Read our full comparison of red light therapy vs. infrared sauna to understand which one to prioritize based on your specific goals.

How Recovery Services Fit Into Your Training Program

Recovery does not work in isolation. A red light therapy session paired with poor nutrition and inadequate sleep will help, but the real gains come when every element works together. That’s why PEAKFIT’s 360 approach integrates training, nutrition, and recovery as one connected system.

Our trainers account for your recovery capacity when designing your program. If you’re using red light therapy consistently, that’s information that influences how they structure your training volume and intensity. Recovery is built into the plan — not left as an afterthought.

Frequently Asked Questions

Is red light therapy safe?

Red light therapy at the wavelengths used in clinical and wellness settings is considered safe for most adults. It is non-thermal and non-UV. People with photosensitive skin conditions, those taking photosensitizing medications (some antibiotics and retinoids), and anyone with active cancer should consult a physician before starting. Book a free consultation to discuss whether red light therapy is right for your situation.

How many sessions before I notice results?

Many clients notice reduced soreness after their first session. Meaningful cumulative benefits — improved joint comfort, skin changes, and sustained recovery improvements — typically become clear after four to six consistent sessions. Most research showing significant results uses protocols of two to three sessions per week for four to eight weeks.

Can I use red light therapy if I have implants or hardware from a prior surgery?

This depends on the type of implant and location. For most common orthopedic hardware (joint replacements, rods, screws), red light therapy is considered safe. If you have concerns about specific implants, consult your surgeon. We’re happy to help you think through it during a free consultation.

What’s the difference between red light therapy and a tanning bed?

Completely different technology and purpose. Tanning beds use UV light to stimulate melanin production, which damages DNA in skin cells. Red light therapy uses non-UV visible and near-infrared wavelengths that have no tanning effect and stimulate cellular repair rather than damaging it. There is no skin damage risk from properly calibrated red light panels.

Do I need to do anything special to prepare?

Come with clean skin — no heavy lotions or oils on the areas being treated, as these can block light penetration. Drink plenty of water before and after. Beyond that, no preparation is required.
