Quick Answer

Red light therapy works at the cellular level — stimulating mitochondrial ATP production to accelerate muscle repair and reduce localized inflammation. Infrared sauna works systemically — using heat to increase circulation, clear metabolic waste, and trigger the parasympathetic recovery response. Both help with muscle recovery and soreness. They work through different mechanisms and complement each other rather than compete. Most PEAKFIT clients use both.

This is the most common question our team gets about recovery services. And it makes sense to ask — both red light therapy and infrared sauna are promoted for muscle recovery, both are available at PEAKFIT Studio in Arden, and from the outside, both involve sitting in a room with technology doing something to your body.

But the mechanisms are completely different. Understanding how each one works makes the choice obvious — and in most cases, it’s not actually a choice between them.

Red Light Therapy: What It Actually Does

Red light therapy (photobiomodulation) uses specific wavelengths of visible and near-infrared light — typically 630 to 850 nanometers — to stimulate energy production inside your cells. The light is absorbed by mitochondria, which respond by producing more ATP, the energy currency your cells use for repair and function.

The practical results of this cellular stimulus, according to a 2016 meta-analysis in Photomedicine and Laser Surgery, include significantly reduced delayed-onset muscle soreness (DOMS), lower creatine kinase levels (a marker of muscle damage), and faster return to performance (Photomedicine and Laser Surgery, 2016). A 2019 review in the Journal of Inflammation Research confirmed consistent reductions in pro-inflammatory cytokines in musculoskeletal tissue following red light treatment (Journal of Inflammation Research, 2019).

Red light therapy is also the stronger choice for skin health benefits. Research published in Photobiomodulation, Photomedicine, and Laser Surgery has shown meaningful improvements in collagen production, skin tone, and reduction in fine lines with consistent use — typically 3 to 4 sessions per week over two to three months.

It produces no heat and requires no sweating. Sessions are comfortable and passive. You sit near the panel, light does its work, you leave. Read our full overview of red light therapy at PEAKFIT for detailed session information and pricing.

Infrared Sauna: What It Actually Does

Infrared sauna uses far-infrared wavelengths to heat your body from the inside rather than heating the air around you — which is why it operates at lower temperatures than traditional saunas while producing stronger physiological effects.

The primary recovery mechanisms are heat-based and cardiovascular. As your body temperature rises, circulation increases significantly, speeding the clearance of metabolic waste products from muscle tissue. Heart rate elevates similarly to moderate aerobic exercise. Post-session, your body temperature drops, triggering the parasympathetic response — the nervous system state associated with rest, repair, and sleep.

Research in the Journal of Human Kinetics found up to a 47% reduction in DOMS with post-exercise infrared sauna compared to passive rest (Journal of Human Kinetics, 2021). A long-term study in JAMA Internal Medicine found significant cardiovascular health benefits from regular sauna use, including improved endothelial function and reduced arterial stiffness (JAMA Internal Medicine, 2015).

Infrared sauna also tends to be more effective at producing full-body relaxation and stress reduction — benefits that matter enormously for people managing high-stress professional lives alongside demanding training schedules.

Which One Should You Choose?

Choose red light therapy as your priority if:

Your primary goal is accelerating acute muscle repair after training
You want skin health benefits alongside recovery
You have joint pain or inflammation that you’re managing chronically
You’re sensitive to heat or find saunas uncomfortable
You’re in a period of high training volume where cellular recovery is the limiting factor

Choose infrared sauna as your priority if:

Your primary goal is soreness reduction and feeling better the day after training
You carry a lot of chronic stress and want a recovery tool that doubles as nervous system regulation
You’re working on cardiovascular health alongside your fitness goals
Sleep quality is a concern — sauna’s post-session temperature drop supports sleep onset
You want a more accessible price point for regular use

Use both if:

You’re in an intensive training block and want comprehensive recovery support
You want to address cellular, systemic, and nervous system recovery simultaneously
You’re combining recovery sessions with one-on-one personal training

Many PEAKFIT clients schedule red light therapy immediately post-workout, then move to the infrared sauna. The combination takes 60 minutes total and covers the full spectrum of post-exercise recovery needs.

What About Assisted Stretching and InBody Scans?

If you’re building out a complete recovery toolkit, two other services at PEAKFIT are worth considering alongside sauna and red light.

PNF assisted stretching with Dakota Hall addresses mobility restrictions that limit movement quality and accumulate over time from training and prolonged sitting. It’s a distinctly different recovery tool — focused on the neuromuscular and connective tissue systems rather than the cellular and circulatory ones.

InBody body composition analysis is not a recovery treatment, but it provides the data that makes every recovery and training decision more precise. Knowing your skeletal muscle mass, body fat percentage, and visceral fat levels puts numbers behind what you’re working toward.

Together with training and nutrition, these four services make up the recovery side of PEAKFIT’s 360 approach to fitness.

Frequently Asked Questions

Can I do red light therapy and infrared sauna in the same visit?

Yes, and many clients do. The two work through different mechanisms, so there’s no conflict. Most clients prefer to do red light therapy first (while tissue temperature is at baseline, which may allow for deeper light penetration), then move to infrared sauna. The full combination takes 60 minutes and covers a comprehensive range of recovery needs.

Which one is better for anti-aging?

They address different aspects of what most people mean by anti-aging. Red light therapy has the strongest evidence for skin-specific effects — collagen production, texture improvement, reduction in fine lines. Infrared sauna has stronger evidence for cardiovascular and metabolic health markers associated with longevity. If skin is the primary concern, red light is the priority. If overall healthspan is the goal, both have a role.

How often should I use each service?

For red light therapy: two to four sessions per week for optimal recovery and skin effects. For infrared sauna: two to four sessions per week, ideally linked to training days. Your PEAKFIT trainer or our front desk team can help you schedule sessions around your training calendar.

Are there any conditions where one is recommended over the other?

People with photosensitivity conditions or who take photosensitizing medications should be cautious with red light therapy. People with uncontrolled hypertension or active cardiovascular conditions should consult a physician before infrared sauna use. For most healthy adults, both are safe and complementary. If you have specific concerns, a free consultation is the right starting point.

Does PEAKFIT offer packages that include both services?

Yes. View our full pricing and package options for the current combination offers. Recovery service packages are also available for clients enrolled in personal training programs.
