7 Health Benefits of Infrared Saunas

Medically Reviewed by | Heidi Wright, BSN, RN, PCCN

Executive Summary

This Mito Red Light article explores how infrared saunas use infrared light to gently heat the body from the inside out at lower air temperatures than traditional saunas, providing a comfortable way to support whole body wellness. Different setups emphasize near infrared (often associated with skin and surface circulation), mid infrared (muscle and soft tissue), far infrared (deeper heating, circulation and sweating) or full spectrum combinations. Potential benefits described in clinical and wellness literature include cardiovascular support, muscle recovery, support for weight management, improvements in skin appearance, relaxation, stress reduction and better sleep. While generally well tolerated, hydration and medical guidance are important, especially for people with cardiovascular or chronic health conditions. Practical use centers on pre session hydration, moderate temperatures (around 100-130°F), timed sessions of about 10-30 minutes, minimal clothing for better exposure and gradual cool down and rehydration afterward. Infrared sauna use can also be combined with red light therapy from Mito Red Light panels for a more complete light and heat based wellness routine.

Key Takeaways:

• Infrared saunas use infrared light to directly heat the body, usually at more comfortable air temperatures than traditional steam saunas.
• Different infrared wavelengths (near, mid, far and full spectrum) are marketed for distinct goals such as skin support, muscle comfort and deeper relaxation.
• Reported benefits include support for cardiovascular function, muscle recovery, weight management efforts, skin health, stress reduction and sleep quality.
• Safety considerations include staying hydrated, limiting session length and consulting a doctor if you have heart disease, high blood pressure or chronic conditions.
• Combining infrared sauna sessions with targeted red light therapy from Mito Red Light can help support both systemic and cellular wellness in the same routine.

In the quest for practical, at home wellness tools, infrared saunas have quickly moved from niche to mainstream. They offer many of the traditional sauna benefits - sweat, relaxation and a pleasant endorphin boost - at lower, more tolerable temperatures.

Unlike traditional saunas that heat the air first, infrared units use emitters to warm your body directly. At Mito Red Light, we focus on technologies that fit real life while aligning with emerging research. This guide explains the different types of infrared saunas, their potential benefits and safety considerations, and how to pair them with Mito Red Light therapy devices for a more complete light and heat based wellness routine.

What Are Infrared Saunas?

Infrared saunas are a type of sauna that use infrared heaters to emit infrared light that is felt as radiant heat and absorbed directly by the skin. Instead of superheating the air to warm you indirectly, they deliver heat to your body more directly, so the air temperature can stay lower while you still sweat and experience a deep warmth.

Typical infrared sauna temperatures are in the 100-140°F range, compared with 160-195°F for many traditional saunas. This makes them appealing to people who find classic sauna heat too intense but still want the relaxing and circulation supporting effects of regular heat therapy.

What Are The Different Types Of Infrared Saunas?

Infrared saunas differ not only in size and construction but also in the infrared wavelengths they emphasize. Understanding these categories can help you match your sauna setup to your goals and decide how to pair it with standalone red light therapy panels.

Near Infrared Saunas (NIR)

Near infrared (NIR) saunas emphasize shorter infrared wavelengths that are often delivered with LEDs or specialized emitters. These wavelengths primarily interact with the skin surface and very superficial tissues and are often marketed for support of skin health, surface circulation and cellular energy near the surface.

Some near infrared units integrate LED arrays similar to those used in red light therapy for skin, creating a hybrid environment where you get both radiant heat and light based photobiomodulation.

Mid Infrared Saunas (MIR)

Mid infrared saunas use wavelengths that penetrate somewhat deeper than near infrared and are often positioned as targeting soft tissue and joints. This band is frequently associated with comfort around muscles and connective tissue and with supporting circulation in deeper layers.

People who use mid infrared saunas often do so for general body comfort after exercise or to support everyday joint and muscle well being in combination with movement and stretching.

Far Infrared Saunas (FIR)

Far infrared saunas are the most common type in both home and commercial settings. Far infrared wavelengths primarily create deeper radiant heating of the body, producing a thorough sweat at relatively moderate air temperatures.

FIR saunas are frequently used for goals like circulation support, relaxation, perceived detoxification through sweating and general stress relief. Because the warmth penetrates more gradually, many people find far infrared sessions more comfortable than extremely hot traditional sauna rooms.

Full Spectrum Infrared Saunas

Full spectrum saunas combine near, mid and far infrared emitters into a single cabin. These setups aim to deliver surface level benefits associated with NIR, soft tissue support associated with MIR and deeper, whole body warmth associated with FIR in one session.

Some full spectrum systems also allow you to adjust which emitters are active during a session, providing more customization if you want to emphasize relaxation, muscle recovery, skin support or a mix of all three.

What Are The Potential Health Benefits Of Infrared Saunas?

Once you understand how infrared saunas differ from traditional steam rooms, you can better evaluate the benefits described in clinical trials and wellness articles. While research is ongoing, several effects are consistently reported.

1. Cardiovascular System Support

Regular infrared sauna use has been investigated for potential cardiovascular benefits. Sitting in the gentle heat can raise heart rate and dilate blood vessels, creating a mild cardiovascular response that resembles low to moderate intensity exercise for some users.

For people who cannot tolerate the intense heat of traditional saunas, infrared cabins offer a lower temperature way to explore heat exposure as part of a broader heart healthy lifestyle that also includes nutrition, movement and medical care.

2. Support For Muscle Recovery

Far infrared therapies have been studied for muscle recovery and discomfort. The penetrating warmth increases local blood flow, helping deliver oxygen and nutrients while moving metabolic byproducts away from worked muscles.

This combination of increased circulation and gentle heat induced relaxation can help reduce stiffness and soreness after training or long days on your feet. Athletes and active individuals often incorporate infrared sauna sessions between workouts to complement sleep, nutrition and other recovery tools.

3. Weight Management Support

Infrared sauna sessions may contribute modestly to weight management efforts by temporarily increasing heart rate and metabolic demand as your body works to cool itself. Some small studies and wellness reports liken the calorie expenditure of a session to that of light exercise.

On their own, sauna sessions are not a magic weight loss tool, but when combined with a balanced diet and regular movement, they can support a comprehensive plan for improving body composition and metabolic health.

4. Skin Health And Tone

Infrared sauna use can support skin appearance by promoting circulation and sweat based cleansing. Increased blood flow helps deliver nutrients and oxygen to the skin, and gentle, repeated sweating may help keep pores clearer for some users.

Many people also pair infrared heat with targeted red light therapy for skin aging to support collagen, elasticity and overall tone in a more targeted way than heat alone.

5. Relaxation And Stress Reduction

Infrared saunas are widely used for relaxation and stress relief. Warmth helps relax muscles and can encourage the parasympathetic "rest and digest" response. Some reports suggest sauna use may help balance cortisol levels and increase endorphins, contributing to a sense of calm.

"Sauna therapy can be strategically paired with meditation to create a powerful strategy for promoting mental well-being. By combining the stress reducing effects of sauna therapy with the focused practice of meditation, individuals have a powerful self-care tool for promoting mental well-being," notes Heidi Wright, Registered Nurse.

6. Sleep Support

By easing muscle tension and promoting relaxation, infrared sauna sessions may help some people fall asleep more easily and sleep more soundly. Many users report that an evening sauna routine helps them unwind and transition into deeper sleep.

Because high quality sleep is crucial for immune function, recovery and mood, this indirect benefit is one reason infrared saunas are popular in holistic wellness programs.

Are Infrared Saunas Safe For Everyone?

Infrared saunas are considered low risk for many generally healthy adults, but heat exposure is not appropriate for every person or medical condition. It is important to consider individual factors and get medical clearance when needed.

Suitability For People With Cardiovascular Conditions

People with cardiovascular conditions such as heart failure, arrhythmias or uncontrolled high blood pressure should talk with their cardiologist or primary care provider before using any sauna. While some studies suggest potential benefits, heat exposure increases heart rate and blood vessel dilation and should be introduced cautiously and under medical guidance.

Effects On Chronic Health Conditions

Some people with chronic conditions - including certain types of pain, mild arthritis or fatigue - report symptom relief with infrared sauna use. Others may find heat exacerbates their symptoms. Because responses vary, a healthcare provider who knows your history is best positioned to advise whether sauna use is appropriate and how to start.

High Temperatures And Hydration

Infrared sauna sessions raise core temperature and induce sweating, which can contribute to dehydration if you are not careful. It is important to drink water before and after your session and to avoid alcohol or heavy meals right beforehand.

People with conditions that affect body temperature regulation, those on certain medications and pregnant individuals should seek medical guidance before using saunas.

Potential Side Effects

Most people tolerate infrared saunas well, but mild side effects such as dizziness, nausea or headache can occur, especially in new users or at higher temperatures. Starting with shorter, cooler sessions and increasing gradually can help your body adapt.

Monitoring With Regular Use

If you plan to use an infrared sauna regularly, pay attention to how you feel during and after sessions. Adjust temperature, duration and frequency based on your body's feedback and your provider's recommendations, especially if you are managing chronic health issues.

How Do You Use An Infrared Sauna?

Understanding the basic best practices for sauna use can help you enjoy the benefits while reducing the risk of overdoing it.

Step 1: Pre Session Hydration

Drink water before you step into the sauna. Being well hydrated helps your body handle the heat and sweat more efficiently and reduces the risk of feeling lightheaded.

Step 2: Check The Temperature

Infrared saunas do not need to be extremely hot to be effective. A range of about 100-130°F is a common starting point for comfort and benefit. Beginners should stay on the lower end and adjust over time.

Step 3: Time Your Session

Start with short sessions of 10-15 minutes to see how your body responds. As you adapt, you can gradually increase to about 20-30 minutes if you feel well and your provider agrees. Never feel obligated to stay longer than feels comfortable.

Step 4: Wear Minimal Clothing

Wear as little as is comfortable and appropriate - such as a swimsuit or lightweight, breathable clothing - to allow heat and infrared energy to interact with as much skin surface as possible.

Step 5: Bring A Towel

Use a towel to sit on and another to gently wipe away sweat during your session. This helps with hygiene and comfort, especially during longer sessions.

Step 6: Relax And Unwind

Once you are in the sauna and comfortable, use the time to unwind. Some people like to meditate, listen to calming audio or simply breathe deeply and enjoy the warmth.

Step 7: Post Session Cool Down And Rehydration

After your session, step out and cool down gradually. Drink another glass of water or an electrolyte beverage, and give your body a few minutes to return to baseline before showering or resuming activities.

How To Maximize Your Infrared Sauna Experience

Beyond basic safety and timing, a few simple strategies can help you get more from each infrared sauna session.

Complement With Red Light Therapy

Enhance your heat routine by pairing sauna sessions with red light therapy. Red and near infrared wavelengths from devices like the MitoPRO+ Series support cellular energy and recovery and can be used before or after your sauna time.

Because most of us spend the majority of our days indoors under artificial light, dedicated red light sessions can help restore exposure to key wavelengths associated with mitochondrial support, skin health and overall recovery. Using Mito Red Light panels in a separate session or mounted near your sauna can create an efficient, synergistic routine.

Create A Calming Atmosphere

Set up your sauna area with soft lighting, calming music or simple quiet to turn each session into a mini retreat. This enhances the mental health benefits of sauna time and supports a stronger mind body relaxation response.

Use Aromatherapy Thoughtfully

Consider adding aromatherapy with sauna safe diffusers or accessories. Scents like lavender can support relaxation, while citrus or peppermint can feel more energizing. Always follow safety guidance for using essential oils in heat.

Support With A Balanced Diet

Eating a diet rich in fruits, vegetables, lean protein and healthy fats provides antioxidant and nutrient support that complements regular heat and light exposure. Hydrating foods such as cucumbers, berries and citrus also help you stay ahead of fluid needs.

Schedule Regular Sessions

As with most wellness practices, consistency matters. Many people aim for 2-3 infrared sauna sessions per week, adjusting up or down based on how they feel, their schedule and their provider's recommendations.

Pair With Gentle Stretching

Gentle stretching before or after a sauna session can help improve flexibility and increase subjective relief in muscles and joints. Basic stretching routines can also support circulation and fluid movement.

Stay Informed And Consult When Needed

New research on infrared sauna use continues to emerge. Stay in touch with your healthcare team and follow updates from reputable sources, especially if you have medical conditions or are considering significant changes to your routine.

The Bottom Line

Infrared saunas offer a modern, more comfortable take on an ancient wellness practice, providing gentle heat, relaxation and a range of potential health benefits for many users. When used thoughtfully and safely, they can be a valuable addition to a broader wellness plan that also includes sleep, nutrition, movement and medical care where needed.
