How to use infrared light therapy for muscle recovery

Muscle Recovery, Longevity

In a world where you’re balancing responsibilities at home with work, workouts, and your long-term wellness, recovery can feel like yet one more decision to figure out. Sunlighten has designed a Guide to Recharging Your Body for Rest & Recovery to simplify that process. 

Inspired by pro-level insight but tailored for everyday life, this guide helps your body’s signals and choose the right recovery tool without overthinking it. Whether you need infrared sauna therapy, red light therapy, cold therapy, or contrast therapy for muscle recovery, you can recover with more intention.

 Infrared sauna for muscle recovery and peak performance

Based on protocols that help professional athletes reset before high-stakes moments, this guide works just as well for those of us navigating demanding days. It’s a simple tool that helps you recover from everyday stress and physical strain faster so you can get back to doing what you love.  

How infrared sauna can help muscle recovery 

Infrared saunas are great for muscle recovery. Infrared therapy has a unique ability to promote full-body healing without creating more stress on the system. With consistent use, it can:  

  • Stimulate circulation and oxygen delivery  
  • Support the body’s natural inflammatory response   
  • Promote relaxation and help activate the parasympathetic nervous system  
  • Encourage hormone balance and deep cellular recovery  

The mPulse Smart Sauna offers six science-backed wellness programs, including muscle recovery, to help reduce inflammation and support cellular repair so you recover faster.

Recovery should match the kind of fatigue you’re feeling

This guide helps you quickly identify what kind of recovery your body is asking for so you can give it the right recharge: 

  • Metabolic fatigue: You feel heavy, sluggish, mentally foggy, or low in energy 
  • Mechanical fatigue: You’re stiff, sore, or tight in specific areas  

Matching your fatigue to the right therapy is what makes this approach so effective.  Cold therapy, contrast therapy, red light therapy and infrared therapy all have a place, but their effectiveness depends on what you’re feeling and when you use them.  

Protocol A: Metabolic fatigue

 Follow this protocol if you’re experiencing these symptoms 

  • Heavy legs 
  • Lazy feeling in your body 
  • Lack of energy or ‘pop’ when you run 

Treatment: Infrared sauna therapy 

  • Duration: 30-40 minutes 
  • Temperature: 110-140 degrees 

Why it works 

  • Increases blood flow 
  • Increases hormonal response to help adapt to exercise stress 
  • Increases circulation, which helps the body process inflammation and recover 
  • faster because blood flow delivers nutrients and oxygen 
  • Penetrates the body to increase body temperature at lower temps, reducing chance of dehydration and energy drain 
  • Delivers photon energy to cells, helping to increase energy  rather than drain it 

Protocol B: Mechanical fatigue

Follow this protocol if you’re experiencing these symptoms 

  • Soreness 
  • Specific muscle soreness 
  • Muscle tissue damage 

Treatment: Cold therapy or contrast therapy 

  • Alternating cold shower or ice bath 
  • Duration: 30 seconds – 2 minutes 
  • Infrared Sauna: 15 to 20 minutes at 110-140 degrees 

Why it works 

  • Cold reduces blood flow and prevents inflammation 
  • Contrast therapy helps flush areas of the body and bring new oxygenated blood where needed 

Red light therapy for muscle recovery: where it fits

Red light therapy is a helpful addition to a muscle recovery routine when you want more targeted support. It’s often used to support specific areas that feel overworked, tight, or are taking time to bounce back.  

While infrared sauna has a systemic effect, red light therapy for muscle recovery provides more localized support. Together they create a fuller approach to feeling restored and recharged.

How to use infrared sauna after a workout 

If you’re not sure where to start, keep it simple. After a tough workout or physically demanding day, ask yourself if you feel holistically drained or specifically sore?  

Start with infrared sauna if you feel the need to recharge with a cellular energy boost. Start with cold therapy if you feel tight or tender in specific areas. Or try contrast therapy and follow the cold treatment with infrared sauna to support a more complete recovery. As a targeted add-on, you can also use red light therapy for muscle recovery. This makes your recovery routine more personalized and effective.  

FAQ
