Finnish Sauna vs Infrared Sauna: Understanding the Differences for Recovery
Introduction
Heat has long been used as a tool to support recovery, relaxation, and overall wellbeing. Today, different forms of sauna offer distinct ways of experiencing this effect, with Finnish and infrared saunas being among the most common.
While both rely on heat, the way that heat is delivered — and how the body responds — differs. Understanding these differences can help clarify how each approach supports recovery, circulation, and nervous system regulation.
Rather than one being better than the other, each creates a different pathway into the same goal: allowing the body to slow down, release tension, and restore balance.
How Finnish Sauna Works
The Finnish sauna is based on high ambient heat, typically ranging between 70°C and 100°C. The air itself is heated, and this warmth surrounds the body, gradually increasing skin and core temperature.
This type of heat exposure promotes vasodilation, increasing blood flow and supporting circulation. As the body works to regulate its temperature, heart rate rises in a way that can resemble moderate physical activity (Hannuksela & Ellahham, 2001).
Sweating is a central part of the experience. It helps regulate body temperature and is often associated with a sense of physical release and relaxation.
The intensity of the heat also encourages a shift in the nervous system. As the session progresses, the body tends to move toward a more relaxed state, supporting recovery and reducing accumulated tension.
How Infrared Sauna Works
Infrared sauna operates differently. Instead of heating the air around the body, it uses infrared light to warm the body directly.
This allows for lower ambient temperatures, usually between 40°C and 60°C, while still producing a noticeable warming effect. Because the heat penetrates more directly into the tissues, the experience is often described as more gradual and sustained.
Research suggests that infrared heat can support circulation and may contribute to muscle relaxation and recovery (Beever, 2009). The lower temperature can also make it more accessible for longer sessions, depending on individual comfort.
Rather than the intensity of traditional heat, infrared sauna offers a more subtle form of thermal exposure, often associated with a steady, calming effect on the body.
Differences in Physiological Response
Although both forms of sauna support recovery, the body responds in slightly different ways.
The Finnish sauna creates a more immediate and intense heat stress. This leads to a rapid increase in heart rate, strong sweating, and a pronounced circulatory response. It can feel energising at first, followed by a deep sense of relaxation.
Infrared sauna, in contrast, tends to produce a slower and more gradual response. The lower ambient temperature allows the body to warm progressively, often resulting in a more sustained and less intense experience.
Both approaches can support circulation, muscle relaxation, and recovery. The difference lies in the pathway: one through intensity and contrast, the other through consistency and gentle heat exposure.
Choosing Between Finnish and Infrared Sauna
The choice between Finnish and infrared sauna is often less about effectiveness and more about preference.
Some people are drawn to the intensity and ritual of the Finnish sauna, particularly when combined with cold exposure. Others prefer the milder, more sustained warmth of infrared sessions.
Both can be integrated into a recovery routine, either separately or in combination with other practices. The key is to find an approach that feels sustainable and aligned with the body’s needs.
Over time, the body tends to respond not only to the type of heat, but to the consistency of the practice.
Heat as Part of a Recovery Practice
Heat exposure, in any form, can support the body’s natural recovery processes. By increasing circulation and promoting relaxation, it creates conditions that allow the body to restore itself more effectively.
Regular use has been associated with improvements in cardiovascular function, reduced muscle tension, and an overall sense of wellbeing (Hannuksela & Ellahham, 2001).
When combined with rest — or with practices such as cold exposure — heat can become part of a broader recovery rhythm that supports both physical and mental balance.
At Ladata, a wellness and recovery club in Matosinhos, Porto, both Finnish and infrared sauna are available as part of a self-guided recovery experience. This allows each person to explore different forms of heat and understand how their body responds to each.
Conclusion
Finnish and infrared saunas offer different approaches to the same underlying goal: supporting recovery through heat.
Whether through the intensity of high temperatures or the steadiness of infrared warmth, both methods can help improve circulation, reduce tension, and encourage the body to shift into a state of rest.
FAQ
What is the difference between Finnish and infrared sauna?
Finnish sauna heats the air around the body at higher temperatures, while infrared sauna uses light to heat the body directly at lower temperatures. This leads to different intensity and sensory experiences.
Which sauna is better for recovery?
Both Finnish and infrared sauna can support recovery. The choice depends on personal preference, as each provides different types of heat exposure and physiological responses.
Is infrared sauna less intense than Finnish sauna?
Yes. Infrared sauna typically operates at lower temperatures, creating a more gradual and less intense heat experience compared to traditional Finnish sauna.
Can sauna improve circulation?
Heat exposure from sauna use promotes vasodilation, which can help improve blood flow and support circulation (Hannuksela & Ellahham, 2001).
Where can you experience sauna in Matosinhos, Porto?
At Ladata, a wellness and recovery club in Matosinhos, Porto, both Finnish and infrared sauna are available as part of a self-guided recovery experience designed to support relaxation and wellbeing.
