Infrared sauna therapy uses infrared energy to create a warm environment that differs from a traditional sauna. Instead of primarily heating the surrounding air to a very high temperature, infrared sauna panels emit wavelengths that are absorbed as heat.
This allows an infrared sauna to operate at a lower air temperature than many traditional saunas while still creating warmth and perspiration.
At Spa of Awakening in Naples, FL, guests can book a Full Spectrum Infrared Sauna experience in a private spa setting. Here is how the technology works, what “full spectrum” means, and what you should expect during an appointment.
What Is Infrared Energy?
Infrared is part of the electromagnetic spectrum. Its wavelengths are longer than visible red light and cannot all be seen by the human eye.
People encounter infrared energy naturally as heat. Infrared sauna equipment uses electric panels designed to emit infrared wavelengths in a controlled environment.
When the sauna operates:
- The panels generate infrared energy.
- The energy is absorbed and experienced as warmth.
- Body temperature and heart rate may temporarily increase.
- The body responds to heat by perspiring.
- Fluid is lost through sweat and needs to be replaced.
The experience should feel warm and controlled. It should not cause burning, severe discomfort, dizziness, confusion, or difficulty breathing.
How Is an Infrared Sauna Different From a Traditional Sauna?
Both types of sauna expose the body to heat, but they produce the experience differently.
| Infrared sauna | Traditional sauna |
|---|---|
| Uses infrared-emitting panels | Uses a heater, hot stones, or another heat source |
| Creates warmth more directly | Primarily heats the surrounding air |
| Generally operates at a lower air temperature | Generally operates at a higher air temperature |
| Usually provides dry heat | May provide dry or humid heat |
| Perspiration commonly occurs | Perspiration commonly occurs |
| May feel more gradual | May feel more immediately intense |
Exact temperatures depend on the equipment, settings, ventilation, and facility.
An infrared sauna is not necessarily “better” than a traditional sauna. Some guests simply prefer its lower-temperature environment and gradual warmth.
What Does Full Spectrum Infrared Mean?
Infrared wavelengths are commonly divided into three general ranges:
- Near-infrared
- Mid-infrared
- Far-infrared
A Full Spectrum Infrared Sauna is designed to use more than one range rather than only far-infrared energy.
Online marketing often assigns a different guaranteed health benefit to each range-for example, skin renewal to near-infrared, circulation to mid-infrared, and detoxification to far-infrared. These claims can oversimplify the evidence.
“Full spectrum” describes the ranges the equipment is designed to emit. It does not guarantee that the sauna will:
- Treat a medical condition
- Heal an injury
- Remove toxins
- Cause body-fat loss
- Reverse skin aging
- Cure chronic pain
- Improve cardiovascular disease
The actual exposure also depends on the device, output, distance, temperature, session length, and individual response.
What Happens to Your Body in an Infrared Sauna?
Your Body Feels Warm
As infrared energy is absorbed, you experience warmth. The surrounding room may feel less intensely hot than a traditional sauna, but heat exposure still occurs.
Your Body Begins to Perspire
Perspiration is the body’s natural cooling response.
Some people begin sweating sooner than others. The amount of sweat is affected by:
- Temperature
- Session duration
- Hydration
- Fitness
- Acclimation to heat
- Medications
- Individual physiology
Sweating more does not mean the session is more effective.
Heart Rate May Increase
Heat exposure can temporarily increase heart rate as the body attempts to regulate temperature.
This does not make sitting in a sauna equivalent to cardiovascular exercise. Infrared sauna does not replace walking, strength training, prescribed rehabilitation, or other physical activity.
People with heart or blood pressure concerns should consult a healthcare professional before sauna use.
The Body Loses Fluid
Sweating reduces body fluid. This is why normal hydration before and after a session is important.
Any immediate decrease on the scale is generally related to temporary water loss-not loss of body fat. The weight commonly returns after rehydration.
Why Does Infrared Sauna Operate at a Lower Temperature?
A traditional sauna creates a very hot room and relies heavily on heated air. An infrared system transfers energy differently, so the surrounding air does not need to reach the same temperature to create a warm experience.
Some guests find this:
- More comfortable
- Less stifling
- Easier to tolerate
- Better suited to a quiet relaxation session
Lower-temperature heat can still produce dehydration or heat-related symptoms. It should not be treated as risk-free.
Does Infrared Sauna Heat the Body “From the Inside Out”?
This phrase is commonly used in marketing but can be misleading.
Infrared energy is absorbed at and below the skin’s surface and experienced as heat. It should not be described as heating internal organs or performing a deep cellular detox.
A more accurate explanation is that infrared panels transfer energy without relying only on extremely hot surrounding air.
Does Infrared Sauna Create a “Deeper Sweat”?
Sweat does not have a measurable depth. Describing one form of perspiration as “deeper” than another is primarily marketing language.
Sweat is mostly water and electrolytes. Its main function is temperature regulation.
The liver and kidneys perform the body’s primary waste-processing functions. There is not strong evidence that infrared sauna removes significant amounts of heavy metals, chemicals, or stored toxins.
What to Expect During a Session at Spa of Awakening
Spa of Awakening currently lists Full Spectrum Infrared Sauna appointments as 45-minute sessions.
This appointment may include:
- Check-in
- Instructions
- Time to change or prepare
- The heated sauna experience
- Time to exit and cool down
A 45-minute appointment does not mean every guest should remain in the heated sauna for the entire period.
First-time guests should:
- Tell staff they are new to infrared sauna
- Ask for a conservative starting setting
- Follow equipment-specific instructions
- Pay attention to how they feel
- Leave before the end if they become uncomfortable
- Avoid treating the session as an endurance challenge
View current session options and pricing on the Full Spectrum Infrared Sauna page.
What Does a Session Feel Like?
Experiences vary, but a session may involve:
- Gradually increasing warmth
- Dry heat
- Perspiration
- Quiet relaxation
- Temporary flushing
- A need to cool down afterward
- Thirst from fluid loss
Some people begin perspiring within several minutes, while others take longer. Do not increase temperature or duration simply because you are sweating less than expected.
How to Prepare
Before an infrared sauna appointment:
- Drink water normally during the day
- Avoid alcohol
- Do not arrive dehydrated
- Avoid a very heavy meal immediately beforehand
- Wear loose, comfortable clothing
- Ask what attire is permitted inside
- Remove heat-sensitive electronics
- Disclose relevant health conditions
- Discuss medications
- Tell staff if it is your first session
- Allow time to cool down afterward

What Should You Do During the Session?
During the sauna:
- Sit or rest comfortably
- Follow the recommended setting
- Do not cover warning symptoms
- Avoid sleeping deeply
- Do not consume alcohol
- Keep required safety equipment in place
- Leave immediately if you feel unwell
- Contact staff if you need help
Do not bring a phone, smartwatch, earbuds, or another electronic device into the heated environment unless the facility confirms that it is permitted and safe.
When Should You End the Session?
Leave immediately if you experience:
- Dizziness
- Nausea
- Weakness
- Headache
- Confusion
- Blurred vision
- Chest discomfort
- Difficulty breathing
- Unusual heartbeat
- Significant skin discomfort
- Any symptom that concerns you
Notify spa staff and cool down.
Seek medical assistance if symptoms are severe, include chest pain or breathing difficulty, or do not improve after leaving the heat.
Dizziness is not a normal sign that the sauna is “working.”
What Should You Do Afterward?
After the session:
Cool Down Gradually
Stand up carefully and rest in a comfortable environment. Avoid suddenly beginning intense physical activity.
Replace Fluids
Drink according to your normal needs and thirst. There is no universal number of ounces suitable for everyone.
People with kidney, heart, or other conditions requiring fluid restrictions should follow their healthcare provider’s instructions.
Change Into Dry Clothing
Fresh, loose clothing may feel more comfortable after perspiring.
Cleanse Gently
If you shower, use a comfortable water temperature. Avoid aggressive skin scrubbing.
Monitor How You Feel
Do not drive or perform demanding activity if you feel dizzy, weak, confused, or unwell.
What Are the Realistic Benefits?
Many guests choose infrared sauna for practical wellness reasons:
- A lower-temperature alternative to many traditional saunas
- Dedicated time to relax
- Soothing warmth
- A private, screen-free experience
- A refreshing perspiration experience
- An addition to a personalized spa day
These are more responsible expectations than claims about detoxification, fat loss, injury healing, or treatment of chronic disease.

Infrared Sauna vs. Red Light Therapy
Infrared Sauna and Red Light Therapy are different services.
| Infrared sauna | Red Light Therapy |
|---|---|
| Creates a heated environment | Provides targeted light exposure |
| Perspiration is common | Perspiration is not the primary purpose |
| Much of the body experiences warmth | Exposure may focus on a selected area |
| Requires heat and hydration precautions | Requires device and light-sensitivity precautions |
| Spa appointment is listed as 45 minutes | Timing depends on the service and equipment |
Red Light Therapy should not be treated as a miniature sauna, and an infrared sauna should not be assumed to provide the same light exposure as a targeted photobiomodulation device.
Can Infrared Sauna Help With Weight Loss?
An infrared sauna does not produce meaningful body-fat loss simply by causing perspiration.
Temporary scale changes generally reflect water loss. Rehydration replaces that fluid.
Sauna use does not replace:
- Balanced nutrition
- Physical activity
- Sleep
- Evidence-based medical care
- A professionally guided weight-management plan
Claims that one short sauna session burns hundreds of calories should be treated cautiously.
Can Infrared Sauna Improve Skin?
Heat and perspiration may temporarily make the skin look flushed or feel refreshed. However, infrared sauna should not be expected to:
- Clear acne
- Remove age spots
- Reverse UV damage
- Cure eczema
- Treat rosacea
- Permanently increase collagen
- Replace professional skincare
Heat may worsen certain skin conditions. Consult a dermatologist if you have an active condition or unusual reaction.
Guests primarily interested in skincare may want to explore professional facial treatments.
Who Should Consult a Doctor First?
Ask a qualified healthcare professional before using an infrared sauna if you:
- Are pregnant or may be pregnant
- Have heart or blood pressure concerns
- Have a history of fainting
- Have a condition affecting heat tolerance
- Have kidney disease or fluid restrictions
- Take medication affecting sweating, hydration, heart rate, or temperature regulation
- Have an implanted medical device
- Recently had surgery
- Have an acute injury
- Have a neurological condition
- Are uncertain whether heat exposure is appropriate
Do not use a sauna when you have a fever, active illness, severe dehydration, or impaired ability to recognize and respond to overheating.
