Sauna sceptic or sweat-loving fanatic? Either way, infrared saunas—whether in a cosy home sauna, luxurious garden sauna, or rugged outdoor sauna—are more than just hot air. The short answer? Yes, infrared sauna benefits are real, ranging from better skin to muscle recovery. Keep reading to find out why everyone's warming up to them.

Understanding Infrared Saunas
What is an Infrared Sauna?
An infrared sauna is a type of sauna that uses infrared light to heat your body directly, rather than warming the air around you like a traditional sauna.
This direct method allows for a lower ambient temperature, yet a deeply penetrating heat.
How it Differs from Traditional Saunas
Traditional saunas heat the air first, which then warms your body.
Infrared saunas bypass this and go straight to the source—your skin and muscles—offering a milder, more tolerable experience.
This makes them ideal for people who struggle with the intense heat of regular saunas.
Types of Infrared (Near, Mid, Far)
Infrared saunas are typically categorised into three types based on wavelength:
-
Near Infrared: Best for skin rejuvenation and wound healing
-
Mid Infrared: Targets pain relief and improved circulation
-
Far Infrared: Most effective for detoxification and deep tissue heating
Many modern infrared saunas combine all three for a full-spectrum experience.
How Infrared Saunas Work
Direct Heating Mechanism
Infrared heaters emit wavelengths that are absorbed by the skin and underlying tissues.
This creates a thermal effect without the need to superheat the air.
Your body responds by sweating and increasing circulation.
Temperature Ranges and Session Duration
Typical infrared sauna sessions run at lower temperatures, around 45–60°C (113–140°F).
Sessions usually last 20–40 minutes, depending on your tolerance and experience level.
Always start short and build up gradually.
Key Health Benefits of Infrared Saunas
Enhanced Detoxification and Circulation
Sweating and Toxin Elimination
Sweating is your body's natural detox process, and infrared saunas amplify this effect.
Toxins like heavy metals, BPA, and pollutants may be excreted through sweat.
Improved Blood Flow and Cardiovascular Health
The heat causes blood vessels to dilate, improving circulation.
This mimics the effect of moderate exercise, which can support heart health.
Impact on Blood Pressure
Some research shows regular use may help reduce blood pressure in people with hypertension.
Infrared therapy promotes vasodilation, aiding smoother blood flow.
Pain Relief and Muscle Recovery
Soothing Sore Muscles and Joint Pain
The deep heat helps relax tense muscles and may reduce joint stiffness.
It’s commonly used by athletes to ease post-workout soreness.
Alleviating Chronic Pain Conditions (e.g., Arthritis, Fibromyalgia)
Infrared therapy may help reduce inflammation and pain associated with conditions like arthritis and fibromyalgia.
The warmth can ease discomfort and improve mobility over time.
Aid in Post-Exercise Recovery and Inflammation Reduction
Infrared saunas can help flush lactic acid and reduce post-exercise inflammation.
This promotes faster recovery after intense physical activity.
Mental Well-being and Sleep Quality

Stress Reduction and Relaxation
The warm, calming environment helps lower cortisol levels.
This reduces stress and creates a meditative state.
Improved Mood and Decreased Anxiety
The sauna experience may trigger the release of endorphins and dopamine.
These feel-good chemicals improve overall mood and ease anxiety.
Promoting Better Sleep Patterns
Regular sessions can support better sleep by calming the nervous system and balancing circadian rhythms.
Try using the sauna in the evening for optimal results.
Additional Potential Benefits
Skin Health and Rejuvenation
Clearer Skin and Pore Cleansing
Sweating opens pores and helps clear dirt, oil, and bacteria.
Many users report improved skin texture and fewer breakouts.
Boosting Collagen Production
Near-infrared wavelengths may stimulate collagen production.
This can improve skin elasticity and reduce fine lines over time.
Immune System Support
Enhancing Immune Response
The elevated core temperature mimics a fever, which can stimulate immune function.
This encourages the body to produce more white blood cells.
Potential Role in Fighting Off Colds
Regular sauna use may reduce the frequency of colds by keeping the immune system sharp.
It also helps open nasal passages and alleviate congestion.
Other Benefits
Weight Management (With Appropriate Caveats)
While not a substitute for diet and exercise, sessions can help burn some calories.
This is due to increased heart rate and metabolic activity.
Improved Lung Function
Infrared saunas may help loosen mucus and ease breathing.
This could benefit those with mild respiratory issues like asthma or congestion.
Important Considerations Before Using an Infrared Sauna
Safety Guidelines and Precautions
Hydration and Preventing Dehydration
Always drink water before, during, and after your session.
Infrared saunas can cause significant sweating.
Recommended Session Frequency and Duration
Start with 2–3 sessions per week, around 20 minutes each.
You can build up to daily use if your body adapts well.
When to Avoid (e.g., Certain Health Conditions, Alcohol)
Avoid saunas if you're pregnant, intoxicated, or have certain medical conditions like uncontrolled blood pressure.
Consult a doctor if unsure.
Potential Risks and Side Effects
Overuse can lead to dehydration, dizziness, or fatigue.
Always listen to your body and take breaks if needed.
Consulting a Healthcare Professional
Speak to a healthcare provider if you have chronic illnesses, cardiovascular issues, or concerns about sauna use.
This ensures your safety and maximises benefits.
