Far-Infrared Sauna
How Does Far Infrared Saunas Work?
In a traditional sauna, you are primarily exposed to high air temperatures of around 82–105°C (180–220°F). This can make the air feel very hot and intense, which some people may find uncomfortable, particularly if they have breathing difficulties. As a result, it can be hard to stay in a traditional sauna long enough to experience the full benefits of heat exposure.
Far-infrared (FIR) technology works differently. Instead of simply heating the air, far-infrared saunas gently warm your body’s core directly. Only around 20% of the heat produced warms the air, allowing for a more comfortable experience and longer session times.
Research suggests that heating the body’s core from both the front and back may help stimulate the lymphatic system, immune response, and cardiovascular system. Sweating can help the body expel certain toxins, and FIR wavelengths may support the body’s natural detoxification processes by interacting with the water molecules in our tissues.
Potential Benefits of Far-Infrared Sauna Therapy
Many users of far-infrared saunas report a range of wellbeing benefits. Although individual results may vary, studies and anecdotal experiences suggest that FIR therapy may offer support for:
Improved Circulation
Far-infrared heat may help to promote better blood circulation and stimulate endorphin production. Some studies have indicated that FIR can help reduce lactic acid build-up and support calorie burn.
Skin Health
Far-infrared heat can open pores and promote healthy sweating, which may support clearer skin by helping remove impurities.
Stress and Fatigue Relief
Regular sauna use has been associated with reduced levels of stress. FIR saunas, through their gentle heating effect, may encourage relaxation by influencing the body’s autonomic nervous system.
Muscular and Joint Support
Heat therapy has long been used to ease muscle tension and joint stiffness. Far-infrared saunas may offer a supportive role in helping with muscle recovery, stress relief, and general aches and pains.
Detoxification
Sweating in a FIR sauna may help the body eliminate certain heavy metals and environmental toxins. Some researchers suggest FIR saunas could be more effective at toxin removal compared to traditional saunas.
Immune System Support
Warming the body has been linked in some studies to enhanced white blood cell production, potentially helping the body’s natural defences, although more research is needed.
Cellulite Appearance
Some users find a temporary improvement of the appearance of cellulite by supporting lymphatic drainage.
Comfortable Heat Levels
Far-infrared saunas operate at lower, more tolerable temperatures (typically between 35–50°C / 100–120°F), allowing users to enjoy longer, more comfortable sessions compared to traditional saunas.
How Far-Infrared Saunas Differ from Traditional Saunas
Traditional saunas heat the air to high temperatures, which then warms the surface of your skin. In contrast, far-infrared saunas use gentle, penetrating wavelengths that aim to heat the body more directly at a cellular level. This deep heat is what many users feel makes FIR saunas a more tolerable and effective experience.
While a conventional sauna might trigger sweating through intense ambient heat, FIR technology encourages a deeper, more efficient sweat at a lower, more comfortable temperature.
Are Far-Infrared Saunas Safe?
Far-infrared heat is a natural part of the sunlight spectrum (not to be confused with UV light) and is considered safe for most people when used appropriately. In fact, similar technology is used in hospitals to warm newborn babies.
However, as with any wellness therapy, individuals with certain medical conditions — including pregnancy, cardiovascular issues, surgical implants, or those taking prescription medications — should consult with a healthcare professional before using a FIR sauna.
How to Use a Far-Infrared Sauna Safely
If you are new to FIR saunas, it’s recommended to start slowly — beginning with sessions of 10–15 minutes at around 35–43°C (100–110°F). Gradually, you may increase your session time to 30–45 minutes, depending on your comfort level.
Always ensure you are well-hydrated before, during, and after your sauna sessions. Bringing a bottle of water — ideally with added electrolytes — is strongly recommended.
Who Should Avoid Far-Infrared Saunas?
While FIR saunas are safe for most people, it’s important to seek medical advice if you:
- Are pregnant
- Have cardiovascular issues or a pacemaker
- Have kidney disease
- Have conditions such as lupus, multiple sclerosis, or erythematosus
- Have recently experienced an acute joint injury
- Have surgical implants
- Experience any worsening of symptoms during use
Your safety is our priority. If unsure, please consult with a medical professional before starting far-infrared sauna therapy.
