How to use infrared sauna for recovery

Muscle Recovery, Fitness, Relaxation, Mental Health

In the wellness world, the word “recovery” often gets linked to sore muscles after a tough workout. But recovery is much bigger than that. It’s your body’s ability to bounce back from all kinds of stress—both the good and the not-so-good. Infrared sauna offers the perfect recovery tool. Let’s explore why. 

You recover from intense exercise, but also from lack of sleep, emotional strain, high-pressure meetings, too much screen time, air travel, or even navigating noisy environments. It’s all input, and your nervous system tracks it all. 

At the heart of recovery is one question: How ready is your body to respond today? Infrared sauna therapy can be a powerful tool for recovery—especially when you learn to use it in tune with what your body needs. 

Understanding stress: defining good and bad stress

Stress isn’t inherently bad. In fact, some forms of stress—called hormetic stress—are good for you. Exercise, sauna heat, cold plunges, and intermittent fasting are all examples of stressors that make your body more resilient over time. 

But chronic stress, especially without time to recover, wears you down. It taxes your nervous system, disrupts hormones, impairs sleep, and accelerates aging. Recovery is what determines whether stress becomes strength or strain. 

Infrared saunas help your body reset and recover from all kinds of stress. Now, let’s explore how they can assist in recovery from physical and emotional stress, and how wearables can help track your progress.

You can use it on low settings for a restorative session or at higher settings for an activating, hormetic session. Infrared saunas have been shown to aid relaxation and recovery in many ways: 

  • Improve heart rate variability (HRV) 
  • Support deep, restorative sleep 
  • Lower cortisol levels (your main stress hormone) 
  • Improve circulation and lymphatic flow 
  • Reduce muscle soreness and joint pain 
  • Calm the nervous system through parasympathetic activation 

All of these contribute to the body’s ability to recover faster and more deeply. 

Tune into your body’s own signals

You don’t need wearables to know when your body needs recovery. If you learn to tune into your body’s cues, you can tell when it's time for a sauna session. Here are some signs that your body may need extra recovery time: 

  • You wake up groggy or unmotivated, even after sleep 
  • Your workout feels harder than usual 
  • Your mood is off, or you feel emotionally flat 
  • You’re sensitive to noise, light, or social interaction 
  • You feel overwhelmed or wired, even when nothing’s wrong 
  • You’re craving rest but keep pushing through 

These signals can be subtle, but when you become mindful of them, you’ll know when to use your sauna for deep restoration. 

How to use your sauna based on your recovery needs

Your infrared sauna can be customized to fit your recovery needs. Use it for relaxation or stimulation based on how your body feels. 

Infrared sauna use on low-recovery days

On days when your body needs deeper restoration: 

  • Lower the temperature to 115–125°F 
  • Stay in for 15–25 minutes 
  • Focus on stillness, breathwork, or meditation 
  • Allow your body to absorb the light, not just sweat 

This is your nervous system’s reset time. It’s not about intensity. It’s about absorption and repair. 

Infrared sauna use on high-recovery days

On days when your body is ready to take on more: 

  • Increase the temperature to 130–145°F 
  • Stay in longer—up to 40–45 minutes 
  • Add movement or breathwork inside 
  • Combine with a cold rinse or workout beforehand 

Let the Sunlighten infrared sauna become part of your recovery and performance protocol. 

The recovery secret: consistency

No matter which kind of day it is, the real secret is this: regular use. The benefits of infrared sauna therapy build over time. Studies show that consistent use leads to better results—especially when used several times a week. 

Your recovery score, whether tracked by a wearable or noticed through mindfulness, will improve when you create space for your body to reset often. Infrared light isn’t just a remedy, it’s a rhythm.
