Infrared Sauna

What is Infrared Sauna?

Infrared saunas use panels that emit infrared light — a type of radiant energy just beyond visible red light — to warm your body directly rather than heating the surrounding air. This means the cabin stays at a lower ambient temperature (typically 45–60°C) compared to traditional Finnish saunas (80–100°C), making the experience more tolerable while still producing a deep, penetrating warmth. The infrared spectrum is divided into near (NIR), mid (MIR), and far (FIR) wavelengths, each with slightly different tissue penetration depths and proposed effects.

How does Infrared Sauna work?

Infrared energy penetrates a few centimeters into the skin and underlying tissue, gently raising core body temperature and triggering a sustained sweat response similar to moderate aerobic exercise. This heat stress prompts the cardiovascular system to work harder — heart rate increases, blood vessels dilate, and circulation improves — producing cardiovascular conditioning effects. The heat also relaxes muscles, reduces joint stiffness, and activates the parasympathetic nervous system, helping shift the body into a rest-and-repair state.

What forms does Infrared Sauna come in?

Traditional cabin-style infrared saunas offer the most consistent, full-body exposure and are the format used in most clinical studies. Portable tent-style saunas and infrared blankets are lower-cost alternatives with less even heat distribution. Near infrared lamp panels can be added to existing spaces but require careful positioning. For therapeutic benefit, a full-body cabin with ceramic or carbon fiber FIR panels is the most reliable choice.

Where it comes from:

Traditional sweat bathing — from Finnish saunas to Native American inipi (sweat lodges) to Roman thermae — has been used for millennia for cleansing, healing, and ritual. Modern infrared sauna technology was developed in Japan in the 1960s and became widely commercialized in the 1980s–90s. Japanese physicians formalized 'Waon therapy' (meaning 'soothing warmth') using far infrared saunas as a clinical protocol for heart failure and chronic fatigue, generating much of the foundational research still cited today.

What does Infrared Sauna help with?

• Muscle soreness and exercise recovery: The deep warmth from infrared sauna increases blood flow to sore muscles, helping clear metabolic waste and deliver nutrients for repair. Many athletes use post-workout sessions to reduce delayed-onset muscle soreness and feel ready to train again sooner.
• Chronic pain and fibromyalgia: Regular infrared sauna sessions have shown meaningful reductions in pain intensity for people with fibromyalgia and other chronic pain conditions. The heat relaxes tight muscles, improves circulation to painful areas, and may help calm an overactive pain-signaling system over time.
• High blood pressure and heart health: Sitting in an infrared sauna raises your heart rate and dilates blood vessels in a way that resembles light to moderate aerobic exercise. Over weeks of regular use, this can lead to measurable reductions in blood pressure and improvements in arterial flexibility.
• Congestive heart failure (mild to moderate): Japanese researchers developed Waon therapy — repeated low-temperature far infrared sauna sessions — specifically for heart failure patients who cannot safely exercise. Clinical trials have shown improvements in exercise capacity, heart function markers, and quality of life in these patients.
• Chronic fatigue syndrome: Several small clinical studies, particularly from Japan, found that regular Waon therapy sessions significantly reduced fatigue, pain, and sleep disturbance in people with chronic fatigue syndrome. Improvements were sustained for months after treatment in some participants.
• Stress, anxiety, and burnout: The parasympathetic nervous system activation during infrared sauna sessions creates a genuine relaxation response — reducing cortisol, lowering heart rate variability stress markers, and promoting a calm, rested feeling. Regular use can help break the cycle of chronic stress.
• Joint pain and arthritis: The heat from infrared sauna penetrates into joint tissue, reducing stiffness and temporarily easing pain in conditions like osteoarthritis and rheumatoid arthritis. Some people find morning sessions particularly helpful for reducing the stiffness that makes the first hours of the day difficult.
• Poor circulation: Infrared heat causes blood vessels near the skin and in deeper tissues to dilate, significantly increasing blood flow throughout the body. This can benefit people with chronically cold hands and feet or mild peripheral vascular issues.
• Skin health and appearance: The increased circulation and deep sweating during infrared sauna sessions can improve skin tone, help clear pores, and support a healthy complexion. Some users report improvements in mild acne and skin texture with consistent use.
• Depression and low mood: Whole-body hyperthermia — deliberately raising core body temperature — has shown promising antidepressant effects in clinical research, likely through effects on serotonin pathways and thermoregulatory circuits in the brain. Even a single session has been shown to improve mood noticeably.

What can Infrared Sauna help prevent?

• Cardiovascular disease risk reduction (with consistent long-term use)
• All-cause mortality reduction (associated with frequent sauna use in large epidemiological studies)

Which foods are rich in Infrared Sauna?

Infrared sauna is a physical therapy, not a compound found in food. To get the most from regular sessions, focus on foods and habits that support what the sauna is doing: stay well hydrated before and after each session (coconut water and electrolyte-rich foods like bananas, avocados, and leafy greens help replace what you sweat out). Anti-inflammatory foods — fatty fish, berries, extra virgin olive oil, turmeric, and ginger — complement the recovery and pain-relief effects. Avoid heavy meals immediately before a session, and limit alcohol on sauna days as it compounds dehydration risk.

What are the side effects of Infrared Sauna?

• Dehydration: the most common issue; drink 500–750ml of water before and after each session
• Light-headedness or dizziness on standing: especially after longer sessions; stand up slowly
• Low blood pressure episodes: more likely in people on blood pressure medications
• Overheating or heat exhaustion if sessions exceed personal tolerance
• Mild skin irritation or rash in sensitive individuals from sustained heat exposure
• Temporary fatigue after longer or first-time sessions (usually resolves within an hour)
• Exacerbation of hot-flash symptoms in perimenopausal women
• Not recommended during pregnancy, with active fever, or with implanted electronic devices (pacemakers) without physician approval

Good to know:

Infrared sauna is safe for most healthy adults when used as directed. The main risks come from staying in too long, not drinking enough water, or using it under medical conditions that affect heat tolerance. Start with shorter sessions at lower temperatures and build up gradually.

How much Infrared Sauna should you take?

• Recommended daily: 15–30 minutes per session at 45–60°C (113–140°F); beginners should start with 10–15 minutes at lower temperatures and build up over several weeks
• Best time of day: Evening sessions promote deeper sleep by triggering the post-heat body temperature drop that signals sleepiness. Morning sessions work well for those using it for pain relief and daily energy. Avoid within 2 hours of intense exercise if already heat-stressed.
• With or without food: Avoid large meals for 1–2 hours before a session. Light snacks are fine. Always hydrate with water or electrolyte drinks before, during (if tolerated), and after each session.
• Time to effect: Immediate relaxation and muscle relief after a single session; meaningful cardiovascular, pain, and mood benefits typically require 3–4 sessions per week for 4–12 weeks
• How long to take it: No firm cycling required — regular ongoing use is safe and associated with cumulative benefits. Most research protocols used 3–5 sessions per week. Listen to your body; if fatigue accumulates, reduce to 2–3 sessions per week for a period.
