Infrared Sauna Therapy: The Complete Beginner’s Guide

Infrared sauna therapy is becoming one of the most popular wellness trends in recent years. Unlike traditional saunas that use heated rocks or steam to warm the air, infrared saunas use light to directly heat the body. This method creates a more comfortable experience while offering a wide range of potential health benefits.

If you’re curious about what infrared sauna therapy is, how it works, and whether it’s worth trying, this complete beginner’s guide will answer all your questions.

What Is Infrared Sauna Therapy?

An infrared sauna uses infrared light waves to penetrate your skin and heat your body directly, rather than just heating the air around you. This makes it possible to achieve the same benefits of a traditional sauna at lower, more tolerable temperatures (usually 110°F–140°F compared to 170°F–200°F in conventional saunas).

There are three types of infrared wavelengths used in saunas:

  • Near Infrared (NIR): Primarily supports skin health, wound healing, and cell regeneration.

  • Mid Infrared (MIR): Helps with circulation, pain relief, and soft tissue recovery.

  • Far Infrared (FIR): Aids in detoxification, relaxation, and deep tissue heating.

Modern infrared saunas often combine all three wavelengths for a full-spectrum experience.

Key Benefits of Infrared Sauna Therapy

1. Detoxification

Sweating is one of the body’s natural ways to eliminate toxins. Infrared heat penetrates deeply, encouraging more intense sweating at lower temperatures, which may help flush heavy metals and environmental toxins.

2. Improved Circulation

As your body warms, blood flow increases. This improved circulation delivers oxygen-rich blood to muscles and joints, which can speed recovery and reduce stiffness.

3. Stress Relief & Relaxation

Infrared sauna sessions are calming. The gentle heat promotes relaxation by lowering cortisol (the stress hormone) and stimulating endorphins, leaving you with a deep sense of calm.

4. Weight Loss Support

While an infrared sauna isn’t a substitute for exercise, it can temporarily boost your heart rate and metabolism. A 30-minute session may help burn calories in a way similar to light cardio.

5. Pain Relief

Many people use infrared sauna therapy for chronic pain conditions such as arthritis, fibromyalgia, and muscle soreness. The deep heat relaxes muscles and reduces inflammation.

6. Skin Health & Anti-Aging

Infrared therapy promotes collagen production, improves circulation to the skin, and may reduce fine lines, wrinkles, and blemishes. Many users notice a healthier, more radiant glow after regular sessions.

7. Better Sleep

The combination of reduced stress, relaxed muscles, and lower cortisol levels often leads to improved sleep quality. Many sauna enthusiasts find sessions in the evening particularly helpful.

How to Use an Infrared Sauna as a Beginner

If you’re new to infrared sauna therapy, here are some helpful tips to get started:

  1. Start Slow – Begin with 10–15 minute sessions at lower temperatures (110°F–120°F). You can gradually increase to 25–40 minutes as your body adapts.

  2. Hydrate Well – Drink water before, during, and after your session to prevent dehydration.

  3. Wear Light Clothing or a Towel – Minimal clothing helps your skin absorb the infrared heat.

  4. Listen to Your Body – If you feel dizzy or uncomfortable, leave the sauna immediately.

  5. Shower Afterward – Rinsing off helps wash away toxins released during sweating.

  6. Frequency – Beginners may start with 2–3 sessions per week, eventually working up to 4–5 sessions for maximum benefits.

Who Should Avoid Infrared Sauna Therapy?

Although infrared saunas are generally safe, they may not be suitable for everyone. Consult your doctor before use if you:

  • Have heart disease or circulation issues

  • Are pregnant or breastfeeding

  • Suffer from heat sensitivity

  • Take medications that affect blood pressure or temperature regulation

Always prioritize safety and seek medical advice if you have underlying health conditions.
