Infrared Sauna vs. Traditional Sauna: What’s the Difference? (Kauai Edition)
If you’ve been searching for an infrared sauna on Kauai, you’ve probably come across comparisons between infrared and traditional saunas. Both offer unique health benefits, but they work in very different ways. Understanding the differences will help you choose the right option for your wellness journey.
At Strength Studio Kauai in Poipu and Koloa, we offer the Sunlighten infrared sauna—a modern, science-backed upgrade to the classic heat therapy experience. Here’s how it stacks up against traditional saunas.
Key Differences Between Infrared and Traditional Saunas
| Feature | Infrared Sauna | Traditional Sauna |
|---|---|---|
| Temperature | 120–150°F (comfortable) | 180–200°F (very hot) |
| Heating Method | Light wavelengths heat the body directly | Heats air, which then warms the body |
| Sweat Depth | Deeper, detoxifying sweat at lower temps | Surface-level sweat |
| Circulation Benefits | Boosts blood flow and oxygen delivery | Increases heart rate from heat stress |
| Comfort Level | Easier to tolerate, longer sessions possible | Can feel stifling or overwhelming |
| Additional Benefits | Muscle recovery, skin health, stress relief | Relaxation, traditional detox benefits |
Bottom line: Both saunas help the body relax and sweat, but infrared therapy offers a deeper, more comfortable, and more versatile health experience—making it especially appealing for recovery, detox, and long-term wellness.
Infrared Sauna FAQs
1. What is an infrared sauna?
An infrared sauna uses light wavelengths to gently heat your body directly, instead of heating the air around you. This allows for a deep, therapeutic sweat at lower temperatures compared to a traditional sauna.
2. Is infrared sauna safe?
Yes. Infrared sauna therapy has been studied extensively and is considered safe for most healthy adults. It operates at lower temperatures than traditional saunas, making it easier on the body. As with any wellness practice, check with your healthcare provider if you have underlying medical conditions.
3. What are the health benefits of an infrared sauna?
Infrared sauna use has been linked to:
Detoxification of heavy metals and toxins
Muscle recovery and pain relief
Improved circulation and cardiovascular health
Stress relief and better sleep
Healthier skin and anti-aging support
Research from sources like the Mayo Clinic and JAMA Internal Medicine support these outcomes.
4. How often should I use an infrared sauna?
For general wellness, 2–3 sessions per week is a great starting point. For specific goals such as pain relief, detoxification, or athletic recovery, more frequent sessions may be beneficial.
5. How long should a session last?
Most sessions last between 30–60 minutes. Thanks to the comfortable temperature, many people find it easy to stay in longer than they would in a traditional sauna. Thanks to how heat tolerant we are here on Kauai, most members found they really enjoyed the full 60 minute session.
6. Can I use the sauna every day?
Yes, daily use is safe for most people and can be especially beneficial for those managing chronic stress, soreness, or circulation issues.
7. What should I do before and after a session?
Before: Drink plenty of water to stay hydrated. Avoid heavy meals.
After: Rehydrate, shower if desired, and give yourself time to cool down. Many people feel relaxed yet energized afterward.

8. Who should avoid using an infrared sauna?
According to Sunlighten’s official guidelines, the following groups should consult their physician before using an infrared sauna, or avoid use altogether:
Cardiovascular conditions, obesity, or diabetes – Those with heart disease, high/low blood pressure, circulatory issues, or diabetes should seek medical clearance. Heat stress increases cardiac output and heart rate, which can strain the cardiovascular system.
Medications – Certain drugs (diuretics, barbiturates, beta-blockers, anticholinergics, antihistamines) may impair heat regulation or increase heat-related risks.
Alcohol & drug use – Avoid sauna use while intoxicated or hungover. Alcohol and drugs can impair judgment and increase heat stress on the body.
Elderly individuals – Reduced sweating and circulation can make it harder to regulate temperature. Use lower temps and shorter sessions.
Children – Children’s bodies heat up faster; if used, sessions must be short, low-heat, and supervised. Children under 16 may not use the sauna without parent or legal guardian supervision.
Chronic conditions with impaired sweating – Conditions like Multiple Sclerosis, central nervous system tumors, or diabetic neuropathy may reduce the body’s ability to sweat.
Hemophilia or bleeding disorders – Heat may worsen bleeding risks.
Fever or heat insensitivity – Avoid sauna use when feverish or if unable to sense heat properly.
Pregnant women – Should consult a healthcare provider before use.
Menstruation – Heat may temporarily increase menstrual flow; this is not generally unsafe, but should be considered.
Joint injuries – Avoid heating acute joint injuries until swelling subsides.
Metal implants – Metal rods, pins, or artificial joints typically reflect infrared heat, but consult a doctor first.
Pacemakers/defibrillators – Magnets in sauna construction may interfere with these devices. Always seek medical clearance.
