Tracing back to thermal baths in ancient Greece and Egypt, followed by indigenous sweat lodges and 20th-century hot tubs, heat therapy has a long history in sports recovery. There are many ways to leverage heat following intense exercise, including the use of saunas. Saunas have transitioned from a spa-only amenity to a real part of many lifters’, runners’, and gym-goers’ routines. At many Factory Store Online locations, for example, traditional and infrared saunas are part of the Recovery Studio, just steps from the gym floor.
What does sitting in an enclosed, heated wooden room do for recovery, and how does it benefit your fitness program?
This guide to saunas for muscle recovery will explore what happens to the body under heat exposure, when to use a sauna, what type of sauna might be best post-exercise, and realistic results you can expect.
What Happens to Your Body in a Sauna?
A sauna session raises your core body temperature, as well as your skin temperature. This triggers vasodilation (the widening of blood vessels) and activates heat shock proteins (HSPs for short).
Dry vs. Infrared Saunas
Traditional dry-heat saunas warm the enclosed space by heating volcanic stones. The air inside gets very warm, but the humidity stays fairly low.
An infrared sauna uses infrared lamps that generate warmth and energy through safe levels of electromagnetic radiation. Invisible light penetrates skin tissue to heat muscles from the outside in, without heating the air, so the ambient temperature stays lower. Chuze members can try both types at locations that offer them and see which one feels better after a tough session.
How Does Sauna Use Support Muscle Recovery?
Heat exposure from saunas supports muscle recovery through a few interconnected pathways:
- Increasing blood circulation to muscles
- Reducing muscle soreness
- Helping lower inflammation
- Supporting long-term strength adaptation
Keep in mind, these effects are complementary to a well-rounded recovery routine. They’re not standalone miracle fixes. Let’s break down each in more detail.
Does Sauna Use Improve Blood Flow to Sore Muscles?
Research suggests that the heat-driven vasodilation from sitting in a sauna improves circulation throughout the body. This may help send blood flow (with oxygen and nutrients) to fatigued muscle tissue. Enhanced circulation might also help clear metabolic waste, like lactate, more efficiently.
Can Sauna Sessions Help Reduce Muscle Soreness?
Heat shock proteins help protect cells from exercise-induced stress. Research is still emerging, but since a sauna session activates HSPs, it may support faster muscle recovery and possibly minimize delayed-onset muscle soreness (DOMS).
Also, remember that sauna bathing is a passive recovery tool. A proper warm-up and cool-down before and after every workout, along with regular stretching, is highly recommended.
Does Sauna Use Affect Inflammation After Exercise?
Some studies suggest that whole-body heat exposure can modulate post-exercise inflammatory markers, essentially balancing the chemical signals your body releases after a workout. It’s a bit like cold therapy working in reverse.
Again, it’s best to view this effect as a supportive (not primary) strategy for managing inflammation. Sauna use should be part of a comprehensive recovery program. That’s why the Chuze Recovery Studio pairs saunas with other tools, like compression boots and red light therapy, at many locations.
Can Heat Exposure Support Long-Term Muscle Adaptation?
More research is needed, but some studies suggest that heat shock proteins play a role in cellular repair. This is crucial for muscle recovery and long-term strength adaptation.
Long-term adaptation is how your body changes in response to consistent, repeated stress (in other words, your muscles growing in size due to a regular training routine). So, theoretically, by activating HSPs, sauna use might support this process.
When Should You Use a Sauna for Muscle Recovery?
There’s no single best time to use a sauna as part of your exercise routine. It’s flexible. That said, if you’re focused on supporting muscle recovery, you might want to use one following a workout: either right after or the next day. Having a sauna at your gym makes the right-after option easy. At Chuze, you can finish your cool-down and head straight to the Recovery Studio.

How long should you stay in the sauna? Sessions should be about 10 to 20 minutes to reap the benefits while avoiding dehydration. If you’re a beginner, consider starting with five to 10 minutes.
What Results Can You Realistically Expect?
As mentioned, research into the benefits of saunas for muscle recovery is still emerging. But many people report feeling more relaxed, “looser,” or less sore after a session following an intense workout. With consistent, ongoing use, heat exposure from a sauna might support long-term muscle adaptation.
When it comes to supporting fatigued muscles, a sauna should be viewed as *one* recovery tool. It’s not a replacement for high-quality sleep, hydration, nutrition, a smart training load, active recovery, and rest days.
Who Benefits Most From Sauna-Based Recovery?
These people may get the most out of regular sauna use:
- Frequent trainers (lifters, runners, group fitness regulars, etc.) looking to quickly recover between sessions
- Those who already enjoy heat therapy (or saunas specifically) and want to build it into a consistent post-workout habit
- Anyone looking for a low-effort way to support recovery alongside their existing routine
- Those looking to build a well-rounded wellness ritual with regular exercise and recovery methods
If you have a health condition or are unsure if a sauna is safe for you for any reason, reach out to your healthcare provider for personalized guidance.
What Type of Sauna Is Best for Muscle Recovery?
If the goal is targeted muscle recovery, infrared might be the ideal option. This type of sauna penetrates tissues directly to offer the benefits of improved circulation, lowered inflammation, and cellular repair support.
Research suggests that traditional dry-heat saunas might be better for improving cardiorespiratory fitness than supporting muscle recovery. However, if you prefer a more intense sweat session that supports whole-body relaxation, this type of sauna is a great choice.
