How Infrared Heat Differs From Traditional Sauna Heat
Infrared and traditional saunas work in fundamentally different ways. Learn more about the health benefits of infrared sauna therapy. A traditional sauna heats the air around you to 150-190°F, and your body absorbs that heat from the environment.
This matters because infrared heat reaches below the surface. Traditional saunas rely on convection and conduction, heating the air, which then heats you.
The infrared sauna session experience is also gentler on your cardiovascular system. Your heart rate still increases, but more gradually than in a traditional sauna, making infrared sauna therapy accessible to people who struggle with intense heat.
There are three types of infrared light: near, mid, and far infrared. Far infrared penetrates deepest and is most commonly used in wellness saunas.
What Happens to Your Body During Infrared Sauna Exposure
When you sit in an infrared sauna, your body runs through a predictable sequence of heat responses.
Minutes 0-5: Skin warming and vasodilation. Infrared radiation is absorbed by water in your skin and subcutaneous tissue, raising local temperature.
Minutes 5-15: Sweating begins. Sweat glands activate once skin temperature crosses a threshold (Human temperature regulation under heat stress in health, disease, and injury). Most first-timers notice perspiration around 10-15 minutes, though this varies with cabin temperature, clothing, and individual sweat rate. Sweating is a cooling mechanism, not a detoxification event, the liver and kidneys handle most waste clearance, so treat any 'detox' framing as a wellness claim, not a medical one.
Minutes 15-30: Cardiovascular and circulatory response. Heart rate typically rises into a mild-to-moderate exercise range, and cardiac output increases.
Nervous system and stress response. Heat exposure activates the parasympathetic branch of the nervous system over time, which many users experience as calm or heaviness.
Metabolism and calorie burn. Your body does burn additional calories while regulating temperature, but the amount is modest, comparable to a light walk, not a workout.
What is well supported vs. what is not. Well supported: increased heart rate, sweating, peripheral vasodilation, temporary muscle relaxation, and a subjective sense of calm.
How to Use an Infrared Sauna: A Minute-by-Minute First Session Walkthrough
Your first infrared sauna session should feel straightforward if you know what to expect. Here's what happens, step by step.
Minutes 0-2: Entering and settling in. You'll undress in a private changing area and wrap yourself in a towel.
Minutes 3-5: Initial warmth. You'll start to feel the radiant heat on your skin, gentle at first.
Minutes 6-15: Heat building. Your skin temperature rises noticeably and you'll begin sweating, expected and healthy.
Minutes 16-25: Peak heat exposure. You're now fully warmed, sweating steadily, and your body feels heavy and relaxed.
Minutes 26-30: Final minutes. As your session winds down, notice how your body feels.
Minute 30+: Exit protocol. When your session timer ends, stand slowly and grab your towel.
Here's what happens during a typical first infrared sauna session, from entry to exit.
| Time | What Happens | What to Do |
|---|---|---|
| Minutes 0-2 | Entering cabin, settling on bench | Undress, wrap in towel, sit or lie down |
| Minutes 3-5 | Initial warmth on skin, deeper breathing | Stay calm, breathe normally |
| Minutes 6-15 | Skin temperature rises, sweating begins | Let heat build, notice circulation response |
| Minutes 16-25 | Peak heat exposure, steady sweat, body feels heavy | Focus on breathing, let mind quiet |
| Minutes 26-30 | Body fully warmed, deep relaxation | Reflect or rest as session winds down |
| Minute 30+ | Session ends, possible lightheadedness | Stand slowly, grab towel, cool down gradually |
Infrared Sauna Session Length: Recommended Duration and How Long to Stay
For your first infrared sauna session, aim for 15-20 minutes. That's enough time to reach the therapeutic benefits without overwhelming your system.
As you become more comfortable, gradually extend sessions to 25-30 minutes. Most regular users settle into a 20-30 minute infrared sauna session as their ideal length; there's no benefit to exceeding 40 minutes.
Listen to your body. If you feel uncomfortable or lightheaded before your timer ends, leave early. Your first session is about learning what to expect, not pushing limits.
Frequency matters too. Adhering to established sauna safety guidelines ensures that these frequent sessions remain a sustainable part of your long-term wellness routine regardless of your age.
The recommended duration for an infrared sauna session depends on your fitness level and heat tolerance.
What to Bring to an Infrared Sauna and How to Prepare
Preparation for an infrared sauna is simple, but the right approach depends on your body, health history, and goals. Use this as a decision guide rather than a one-size-fits-all checklist.
What to bring (universal):
- A towel to sit or lie on inside the cabin
- A second towel for after your session
- A water bottle for after (not during, see hydration below)
- Light, loose clothing to change into afterward
- A hair tie if you have long hair
What to wear inside: Most people wear nothing or minimal clothing such as shorts or a swimsuit. Less fabric between you and the infrared heat means more direct exposure.
How to prepare based on your health profile:
- Generally healthy, first-timer: Eat a light meal 1-2 hours before. Avoid alcohol. Take a quick lukewarm shower. Start with a 15-20 minute session at a moderate temperature.
- Athlete or regular exerciser: You may tolerate longer sessions (25-30 minutes) and slightly higher temperatures. Hydrate with an electrolyte drink before and after if you sweat heavily.
- Heat-sensitive or new to sauna: Start with 10-15 minutes at the lower end of the cabin's range. Sit near the door. Tell the staff it is your first time so they can check on you.
- Managing a chronic condition (high blood pressure, heart disease, diabetes, pregnancy): Consult your clinician before your first session. Bring a note if your spa requires it. Start shorter and cooler than you think you need.
- Taking medications: Some medications affect sweating, blood pressure, or heart rate. Ask your pharmacist or doctor whether sauna use is appropriate.
Mental preparation: Set an intention, relaxation, recovery, or stress relief. Silence your phone. Let the spa know you do not want interruptions. A few minutes of quiet breathing before you enter helps you settle faster.
Hydration before: Drink water in the hour before your session, but not so much that you feel bloated. If you are prone to heavy sweating, a modest electrolyte drink beforehand can help.
Infrared Sauna Safety: Recognizing When to Stop and Side Effects to Watch For
Infrared sauna therapy is safe for most people, but you need to know the warning signs. Stop your session immediately if you experience any of these:
- Dizziness or lightheadedness that doesn't ease with sitting down
- Nausea or stomach discomfort
- Chest pain or pressure
- Shortness of breath that feels abnormal
- Confusion or difficulty thinking clearly
- Extreme fatigue or weakness
These symptoms suggest your body has had enough heat exposure. Exit the sauna, cool down gradually, and drink water. If symptoms persist, seek medical attention.
Common side effects that are normal include mild lightheadedness when standing (caused by temporary blood pressure shifts), flushed skin, and temporary fatigue as your body recovers. These fade within minutes to hours.
Watch out: People with uncontrolled high blood pressure, heart conditions, or those taking certain medications should consult their doctor before using infrared sauna therapy. Pregnant women should check with their healthcare provider.
Dehydration is the most common issue. Your body loses fluids through sweat. If you don't rehydrate properly after your session, you'll feel tired or develop a headache. This is easily prevented by drinking water after your infrared sauna session.
What to Expect Immediately After Your Session and Recovery Steps
The minutes right after your infrared sauna session are important. Here's what happens and how to handle it.
Immediately after (0-5 minutes): You'll feel warm and relaxed. Your skin will be flushed. You may feel slightly tired, this is normal. Sit for a moment before standing. Stand slowly. Let your blood pressure stabilize.
Cool-down (5-15 minutes): Your body gradually returns to normal temperature. You may continue sweating for several minutes. This is fine. Let it happen.
Hydration (immediately and ongoing): Drink water as soon as you're comfortable. Aim for 16-24 ounces in the first 30 minutes after your session. Continue drinking water throughout the day.
Rest period (30-60 minutes after): Your body is in recovery mode. This is when many of the therapeutic benefits solidify. Avoid intense exercise or stressful activities for at least 30 minutes.
What you might feel later: Some people experience improved sleep that night. Others feel energized. Muscle soreness may feel slightly better if you used the infrared sauna for recovery.

Frequently Asked Questions
What should I wear during an infrared sauna session?
Wear minimal, breathable clothing or a swimsuit. Many people wear just a towel or undergarments. Avoid metal jewelry, watches, or glasses, as they can conduct heat and become uncomfortable. Choose natural fabrics like cotton if you prefer to wear something. The goal is to allow your skin to absorb the infrared heat directly while staying modest and comfortable.
Is 20 minutes in an infrared sauna enough for beginners?
Yes, 20 minutes is an ideal starting point for your first infrared sauna session. Your body needs time to acclimate to the radiant heat and build heat tolerance gradually. Most beginners feel the full benefits of relaxation and circulation improvement within this timeframe. As you become more comfortable, you can extend sessions to 30 minutes, but always listen to your body and stop if you feel lightheaded or uncomfortable.
Do you have to shower after using an infrared sauna?
Showering after an infrared sauna session is recommended but not mandatory. A cool or lukewarm shower helps rinse away sweat and allows your core body temperature to normalize gradually. If you prefer not to shower immediately, at least rinse your face and drink water to rehydrate. Avoid very hot showers right after, as your body is already warm and needs time to cool down safely.
What does an infrared sauna do for the body during a session?
During an infrared sauna session, the far infrared and near infrared heat penetrates your skin and raises your core body temperature. This triggers a sweat response as your body works to cool itself, increasing heart rate and blood flow to your skin and muscles. The radiant heat promotes relaxation, reduces stress, and supports circulation. Your body also begins natural detoxification through sweating, though the extent depends on individual factors like hydration and overall health.
The difference between wondering what to expect and knowing exactly what happens is the difference between anxiety and confidence. You now have that confidence. Your first infrared sauna session is waiting.
