Infrared sauna therapy uses far-infrared radiation (8–12 micrometres) to heat body tissue directly rather than warming ambient air. At 50–60°C — significantly more comfortable than a traditional sauna — it produces a deeper tissue response, more vigorous sweating, and a range of clinically studied benefits including skin collagen stimulation, cardiovascular support, and pain management. This guide covers the evidence, the protocol, and how to prepare for your session.
Treatment Summary
Far-infrared wavelengths penetrate 4–5cm beneath the skin surface, stimulating fibroblasts, improving circulation, and triggering a detoxification response at lower temperatures than traditional saunas. Clinical evidence supports benefits including 51–75% improvement in skin texture (6-month study), cardiovascular effects comparable to moderate exercise, 86% reduction in major depression criteria (UCSF, 2025, combined with CBT), and reduced chronic pain scores over two years. Optimal protocol: 20–45 minutes per session, 3–7 sessions weekly.

Infrared vs Traditional Sauna
Traditional saunas heat ambient air to 80–100°C, warming the body indirectly. Infrared saunas use far-infrared wavelengths to penetrate 4–5cm beneath the skin surface and heat tissue directly. The result is a more tolerable temperature (50–60°C) with deeper physiological response — more vigorous sweating and more direct cellular stimulation than surface-level heat provides.
| Feature | Infrared Sauna | Traditional Sauna |
|---|---|---|
| Temperature | 45–60°C | 80–100°C |
| Tissue penetration | 4–5cm | Surface only |
| Toxin expulsion | Up to 20% | ~3% |
| Comfort | More tolerable for extended sessions | Can feel oppressive |

At Lady’s Beauty Care we use the Sun Stream Evolve 10 — a 360° surround infrared sauna designed to deliver even heat distribution for maximum skin contact and absorption.
Skin Rejuvenation & Anti-Ageing
The most extensively studied benefit of infrared sauna therapy is skin collagen stimulation. Research published in the Yonsei Medical Journal found that far-infrared exposure significantly increased collagen and elastin production in dermal fibroblasts. A 6-month clinical study using daily 15–20 minute sessions showed 51–75% improvement in skin texture and roughness across all participants, and 25–50% improvement in skin tone, attributed to increased soluble collagen and elastin.
Improved cutaneous blood flow — driven by the vasodilation response to infrared heat — delivers oxygen and nutrients to skin cells while clearing metabolic waste. NASA research on near-infrared light has also demonstrated accelerated wound healing and tissue repair, supporting the use of infrared therapy as a complement to post-procedure skin recovery.
Cardiovascular Health
A systematic review published in Canadian Family Physician analysed 9 clinical studies (Level I and II evidence) on far-infrared sauna therapy for cardiovascular conditions. Findings included reductions in systolic blood pressure, improvements in congestive heart failure markers, enhanced vascular endothelial function, increased exercise tolerance, and decreased BNP levels — with no adverse events reported across all reviewed studies.
Additional research published in ScienceDirect found that infrared sauna sessions produce cardiovascular responses comparable to moderate-pace walking, raising core temperature more effectively than moderate exercise while operating at comfortable ambient temperatures.
Medical note
Infrared sauna is not a replacement for medical cardiovascular treatment. Individuals with cardiovascular conditions, hypertension, or on cardiac medications must consult a healthcare professional before use.
Mental Health & Wellness
In October 2025, UCSF published findings from a clinical trial led by Dr Ashley E. Mason PhD combining whole-body hyperthermia (infrared sauna) with cognitive behavioural therapy for major depressive disorder. 86.2% of participants no longer met criteria for MDD at final assessment. An earlier feasibility study (International Journal of Hyperthermia, May 2024) found 92% of completers no longer met MDD criteria, with acute mood improvements after individual sessions predicting overall treatment response.
Important context
Both studies combined infrared sauna with professional psychotherapy. Infrared sauna alone is not a treatment for clinical depression. Dr Mason describes this as “exciting early work.” Anyone experiencing depression should consult qualified mental health professionals.
Pain Management & Recovery
A two-year Cleveland Clinic study found infrared sauna therapy “may be a promising method for treatment of chronic pain,” with participants showing decreased pain scores, improved blood flow to affected areas, and enhanced mobility across the study period. Research comparing infrared sauna, traditional sauna, and warm water immersion for athletic recovery found infrared sauna most effective for reducing post-exercise fatigue, decreasing blood lactate levels, and preventing muscle damage markers.
Acne & Detoxification
Dermatology Online Journal trials showed reduced acne lesion counts and improved skin texture through consistent infrared sauna use, attributed to anti-inflammatory effects and deep pore clearing through sustained sweating. A Journal of Environmental and Public Health study found sweat from infrared sauna sessions contained up to 20% toxins versus approximately 3% in traditional sauna sweat — including measurably higher heavy metal concentrations.
Usage Guidelines
Research-based protocol
- Temperature: 50–60°C (start at the lower end)
- Duration: 20–45 minutes per session
- Frequency: 3–7 sessions per week for optimal cumulative benefit
- Hydration during session: Sip 250–500ml water throughout
- Exit immediately if you feel dizzy, nauseous, or unwell
Pre & Post-Session Preparation
24–48 hours before
Avoid alcohol
Alcohol dehydrates the body and causes abnormal blood pressure fluctuations. Combined with sauna-induced vasodilation, this creates a cardiovascular safety risk including dizziness and fainting.
Review medications
Beta-blockers, diuretics, and stimulants can impair the body’s natural cooling mechanisms. Consult your prescribing doctor before sauna use if you are on any of these.
2 hours before
Hydrate
Drink 500ml–1L of water before your session. You will lose up to 1 litre of fluid in a 30–45 minute session. Adequate hydration maintains blood volume during vasodilation and supports toxin clearance.
Electrolytes
If you train heavily or are prone to cramping, add an electrolyte drink before you arrive. Magnesium and potassium help prevent muscle cramps during deep heating.
On the day
Arrive with clean skin
Avoid heavy body oils, thick lotions, or petroleum-based products. These reduce skin emissivity — the ability to absorb infrared energy — and block pores, impairing detoxification. Remove makeup and antiperspirant before your session.
Remove jewellery and metal
Metal heats up under infrared exposure and can cause discomfort or burns.
Eat lightly
Avoid a heavy meal in the 1–2 hours before your session. Heavy digestion competes with thermoregulation as blood is redirected to the skin for cooling.
Post-session
Wait 15–30 minutes before a cold shower
Your body continues to burn calories and detoxify for up to an hour after leaving the sauna. Immediate cold exposure interrupts this metabolic continuation. Allow your body to complete its natural cooling cycle first.
Rehydrate with electrolytes
Drink 500ml–1L water post-session. Add coconut water, mineral water, or electrolyte tablets to replace sodium, potassium, and magnesium lost through sweat.
Post-sauna skincare
Gently cleanse skin to remove expelled toxins. Apply moisturiser to slightly damp skin. SPF 50+ if heading outdoors.
Safety & Contraindications
Do not use infrared sauna if you have:
- Pregnancy or actively trying to conceive
- Cardiovascular conditions — without medical clearance
- Blood pressure medications — consult your doctor first
- Heat-sensitive or photosensitive skin conditions
- Recent surgery or acute injury
- Active fever or acute illness
- Inability to regulate core temperature
Integration with Aesthetic Treatments
Infrared sauna therapy complements clinical skin treatments by improving circulation, supporting cellular repair, and enhancing product penetration. Relevant combinations at Lady’s Beauty Care:
- Dermapen 4 Microneedling — enhanced circulation supports collagen production and post-treatment healing

Note: infrared sauna is not recommended within 48 hours of a microneedling or chemical peel session — heat and increased sweating during active healing can cause irritation. Discuss timing with Zeda at consultation.
Frequently Asked Questions
How quickly will I see results?
Mood and skin radiance improvements can be noticed after individual sessions. Significant improvements in skin texture and wrinkles appear after consistent use over 12–24 weeks (3–5 sessions weekly). Cardiovascular and pain management benefits develop over months of regular use.
Is it safe to use in Adelaide summer?
Yes, with strict hydration. The key is maintaining excellent fluid intake before, during, and after. Consider scheduling sessions in the cooler part of the day during extreme heat weeks. Exit immediately if you feel unwell.
Can it help with acne?
Research supports anti-inflammatory and pore-clearing benefits. However, infrared sauna is supportive — not a standalone acne treatment. For active or persistent acne, a consultation to assess the full picture (including appropriate clinical treatments) is the right starting point.
Can it help with depression?
Early clinical evidence is promising, particularly when combined with psychotherapy. This is not a standalone treatment for clinical depression. Anyone experiencing mental health challenges should work with qualified healthcare professionals — infrared sauna may be a useful complement to, not a replacement for, appropriate care.
