Understanding the Heat: Traditional vs. Infrared Saunas
Traditional Saunas:
Traditional saunas have been a cornerstone of Nordic culture for centuries. These saunas typically operate at temperatures between 150-185°F (65-85°C).
They work by heating the air around you, which then warms your body. The heat is generated by warming rocks, often with the option to add water for steam, creating a high-humidity environment.
Infrared Saunas:
Infrared saunas are a more recent innovation. They use infrared lamps to emit light waves that directly heat your body without significantly warming the surrounding air.
These saunas operate at lower temperatures, usually between 120-140°F (49-60°C), making them more tolerable for many users.
The key difference comes from how these saunas heat your body. Traditional saunas work from the outside in, while infrared saunas heat from the inside out. Infrared waves can penetrate up to 1.5 inches beneath the skin, potentially offering a more efficient heating experience.
Health Benefits: A Comparative Analysis
Both the infrared sauna and the traditional sauna types offer an impressive array of health benefits, though the mechanisms behind these benefits can differ.
Cardiovascular Health:
Traditional saunas and infrared saunas both positively affect cardiovascular health. The heat exposure causes your heart rate to increase, similar to the effect of moderate exercise.
A landmark study published in JAMA Internal Medicine in 2015 found that frequent traditional sauna use (4-7 times per week) was associated with reduced risk of sudden cardiac death, fatal coronary heart disease, and all-cause mortality.
While infrared saunas have been less studied, they’ve shown promising results in improving heart health. Some research suggests that the lower temperatures of infrared saunas might make them more accessible for people with heat sensitivity or certain cardiovascular conditions.
Detoxification:
Sweating is a primary mechanism for detoxification in both sauna types. Some proponents of infrared saunas claim that the deeper heat penetration leads to more effective toxin elimination.However, scientific evidence is still limited, and more research is needed to confirm these claims.
Pain Relief and Muscle Recovery:
Both sauna types can be beneficial for pain relief and muscle recovery. The heat helps increase blood flow, which can reduce muscle tension and promote healing.
A 2015 study in the Journal of Human Kinetics found that both infrared and traditional sauna use after endurance training improved neuromuscular performance.
Practical Considerations:
When choosing between traditional and infrared saunas, several practical factors come into play:
Installation and Space Requirements:
Traditional saunas often require more complex installation, including proper ventilation and sometimes specialized electrical work. They also tend to be larger, which can be a consideration if space is limited.
Infrared saunas, being generally smaller and requiring less infrastructure, can be more easily installed in homes with limited space. Many come as portable units that can be set up and taken down as needed.
Energy Efficiency
Infrared saunas typically consume less energy than traditional saunas because of their lower operating temperatures and direct heating method. This can translate to lower operating costs and a smaller environmental footprint.
User Experience
The experience of using each sauna type is quite different. Traditional saunas offer an intense, enveloping heat that many find deeply relaxing and invigorating. The option for steam and the social aspect of traditional sauna bathing are significant draws for many users.
Infrared saunas provide a gentler heat that some find more comfortable, especially for longer sessions. The lower ambient temperature can be less overwhelming for those new to sauna therapy.

Sauna use affects the endocrine system, influencing hormone production and regulation. Studies have shown that sauna bathing can increase growth hormone levels, which may contribute to muscle growth and repair.
Additionally, sauna use has been associated with reduced cortisol levels, potentially aiding in stress reduction.
Detoxification Mechanisms
While both sauna types promote sweating, which can help with detoxification, the mechanisms may differ slightly. Traditional saunas induce profuse sweating through high ambient temperatures, while infrared saunas may cause a more targeted sweat response because of the direct heating of tissues.
Comparing Sauna Types:
A Deeper Look
Temperature and Humidity
Traditional saunas typically operate at higher temperatures (150-185°F) with variable humidity levels, depending on whether water is added to the hot rocks. This creates an intense, enveloping heat that can be adjusted by controlling the humidity.
Infrared saunas function at lower temperatures (120-140°F) with minimal humidity. The infrared rays directly heat the body without significantly warming the surrounding air, creating a more tolerable environment for many users.
Heating Method
Traditional saunas use convection heat, warming the air around you, which then heats your body. This method can take longer to warm up both the sauna and your body.
Infrared saunas use radiant heat, with infrared waves directly penetrating and warming your body tissues. This method can lead to faster heating and potentially more efficient sweating.
Energy Consumption
Due to their lower operating temperatures and more targeted heating method, infrared saunas generally consume less energy than traditional saunas. This can result in lower operating costs and a smaller environmental footprint.
Installation and Maintenance
Traditional saunas often require more complex installation, including proper ventilation and sometimes specialized electrical work. They may also need more maintenance, such as replacing heating elements or rocks over time.
Infrared saunas are typically easier to install and maintain. Many models are portable or can be easily assembled in a home setting without extensive modifications.
Health Benefits:
A Closer Examination:
Cardiovascular Health
Both sauna types have shown significant benefits for cardiovascular health. The heat exposure causes an increase in heart rate and cardiac output, similar to moderate exercise.This can lead to improved cardiovascular function over time.
A large-scale study published in JAMA Internal Medicine in 2015 found that frequent traditional sauna use (4-7 times per week) was associated with a 50% lower risk of cardiovascular-related death compared to those who used saunas once a week.
While less research has been conducted specifically on infrared saunas, preliminary studies suggest similar cardiovascular benefits. A 2009 study published in the Journal of Cardiology found that infrared sauna therapy improved cardiac function and exercise tolerance in patients with chronic heart failure.
Detoxification
Both sauna types promote sweating, which is one of the body’s natural detoxification mechanisms. However, the effectiveness of sauna use for detoxification is a topic of ongoing research and debate.
A 2012 study published in the Journal of Environmental and Public Health found that sweating can help eliminate certain toxic elements from the body, including heavy metals like arsenic, cadmium, lead, and mercury.
Some proponents of infrared saunas claim that the deeper penetration of infrared heat leads to more effective detoxification. While this theory is plausible, more research is needed to confirm whether infrared saunas are indeed more effective for detoxification than traditional saunas.
Pain Relief and Muscle Recovery
Both sauna types have shown benefits for pain relief and muscle recovery. The heat exposure increases blood flow, which can help reduce muscle tension and promote healing.
A 2015 study in the Journal of Human Kinetics found that both infrared and traditional sauna use after endurance training improved neuromuscular performance and reduced muscle soreness.
For chronic pain conditions, such as fibromyalgia, some studies have shown promising results with infrared sauna therapy. A small study published in Internal Medicine in 2008 found that infrared sauna therapy reduced pain and improved quality of life in fibromyalgia patients.
