In This Depth Guid we will Discover exactly what to do before and after an infrared sauna for maximum benefits. Learn expert tips for beginners, weight loss, hydration, post-sauna care, and common mistakes to avoid.
Stepping into an infrared sauna feels like giving your body a warm, embracing hug from the inside out. Unlike traditional saunas that heat the air around you, infrared saunas use light waves to penetrate deep into your tissues, raising your core body temperature and inducing a profound sweat at lower ambient temperatures.
But to truly reap the rewards—ranging from heavy metal detoxification to glowing skin and improved circulation—how you prepare and recover is just as important as the session itself.
If you are wondering what to do before and after an infrared sauna to maximize results, the protocol is simple but specific: hydrate heavily beforehand, avoid heavy meals, allow your body to cool down naturally, and wait to shower.

Key Takeaways
- Hydration is Non-Negotiable: Drink water with electrolytes before, during and after your session in order to stay away from dehydration and headaches.
- The 30-Minute Rule: Do not eat heavy meals 1-2 hours before entering, and don’t shower for at least 30 minutes after exiting the infrared session to allow your body to cool down and absorb the benefits of the infrared.
- Listen to Your Body: If you are a beginner, start slowly (15-20 minutes), and increase to 40-minute sessions.
- Don’t Rush the Cool Down: The period immediately after the sauna is when your body does much of its healing work; don’t shock your system with cold water immediately.
Phase 1: What to Do Before an Infrared Sauna
Preparation is the key to a successful session. If you go on a walk in a dehydrated, or full stomach, then you won’t feel the benefits – you’ll likely just feel nauseous.
How to Prepare for an Infrared Sauna: Hydration First
The single number one most important thing in how to prep for infrared sauna sessions is water intake. You are just about to lose a lot of fluid through sweat.
- Drink Up: Drink at least 16-24 ounces of water 30 to 60 minutes before you will be exercising.
- Electrolytes: Water is not always enough. Adding electrolytes (magnesium, potassium, sodium) to retain fluid in your cells. Without them, you may feel lightheaded or you may get a “sauna headache.”
Dietary Considerations
Many people ask “How long after eating infrared sauna use is safe?” You should not eat heavy meals at least 1 to 2 hours before. Digestion needs the blood to flow to your stomach.
If your body is trying to digest a steak dinner and you are trying to sweat you are splitting your resources and cramping or nausea will ensue. However, do not starve yourself, a light snack such as a banana or nuts is ok if you are feeling faint.
Clothing and Skin Care
When it comes to what to do before infrared sauna sessions when it comes to clothing, less is more. Ideally, wear loose fitting cotton or go naked if you are in a private setting.
- Remove Makeup: You want your pores to breathe. Heavy makeup or lotion can be clogging up the sweat gland and can prevent the deep detox.
- Remove Jewelry: Metal heats up fast and can burn your skin.
Infrared Sauna Tips for Beginners
If this is your first time, understanding how to prepare for an infrared sauna session consists of managing expectations.
- Temperature: Set the temperature in the sauna from 100°F to 120°F. Contrary to traditional saunas that operate at 180F, infrared saunas work at lower temperatures.
- Duration: Begin with 15 to 20 minutes. Don’t try to be a hero for 45 minutes your first go.
Phase 2: What to Do During an Infrared Sauna Session
During the Session
- Towel Use: Bring two towels. One to sit on (protect the wood from your sweat) and one to wipe your face.
- Silence or Sound: Lots of people take this time to meditate. However, listening to a podcast or music is OK – just not stressful news.
- Movement: It is true that gently stretching your neck and shoulders can help to loosen the muscles, but in general, you shouldn’t move – as this would cause your heart rate to fluctuate.
1. Monitor Your Time and Temperature
- Beginners: 15–25 minutes
- Experienced: 30–45 minutes
- Optimal temperature: 110–140°F
2. Listen to Your Body
If you feel dizzy, excessively fatigued, or nauseous, exit immediately. Infrared saunas are therapeutic, but safety is paramount.
3. Use Infrared Sauna for Weight Loss
Infrared heat increases your heart rate, circulation, and calorie burn. Pairing your session with a healthy diet and light exercise enhances weight loss results.
Phase 3: What to Do After an Infrared Sauna
The moment you step out your body is in a very active state. Your pores are open, your blood is pumping and you are probably dripping with sweat. Here is just what to do right after infrared sauna to lock in the benefits.
The Cooling Down Process
Do not rush. Your body requires to get out of the heated state and get into the normal state slowly.
- Cool Down: Sit wrapped in a robe or in a towel for about 5-10 minutes. Allow your body to keep on sweating for some time. This is what the detox process is about.
- Listen to your body: If you feel dizzy, sit down right away and have some water.
Showering Protocols: The Golden Rule
One of the most common questions is this: should you shower after infrared sauna use? The answer is yes but timing is everything.
- How Long to Wait to Shower after Infrared Sauna? Ideally, wait 15 to 30 minutes at least.
- Why wait? Since the infrared heat raises your core temperature, your body is still sweating and detoxifying after you get out of the cabin. Showering immediately washes away the toxins but it shocks the system too.
- Warm vs. Cold: Begin with a shower at lukewarm water. Finishing off with a blast of cold water is a popular technique (contrast therapy) to close pores, boost circulation, but it’s not for everyone.
Re-Hydration and Nutrition
You just lost a lot of water. What to eat after infrared sauna sessions is as important as water.
- Water: Drink an additional 16-24 ounces of water immediately.
- Food: You need to eat a meal rich in nutrients within an hour. Since you have just completed detox, don’t put the junk back into your system. Think leafy greens, lean proteins and antioxidant-rich fruits. This replenishes the minerals that are lost during sweat.
Safety Deep Dive: Can Infrared Saunas Cause Cancer?
This is a legitimate concern and a question we need to answer using science. Can infrared saunas give cancer? The short answer to this is no. Infrared heat is just radiant heat. It is the same type of heat that we would get from the sun without the harmful UV rays
Infrared heaters emit far-infrared light (on the other end of the spectrum from ultraviolet light). While UV light can be used to cause damage to DNA and cause skin cancer, far-infrared light is non-ionizing and safe.
In fact, some studies suggest that infrared therapy may actually help inhibit the growth of cancer cells by helping to improve circulation and oxygenation, though you should always consult an oncologist for advice about any specific type of medical approach.

To help you visualize how the perfect routine will look, here is a snapshot of how the perfect routine timeline will be.
| Phase | Action | Why It Matters |
|---|---|---|

| During (15-40 min) | Relax, Meditate, Sweat | Core temperature rise; detox begins. |
| Post-Sauna (0-15 min) | Cool down slowly in a robe | Body continues to eliminate toxins. |
| Post-Sauna (15-30 min) | Warm then cool shower | Washes off toxins; closes pores. |
| Post-Sauna (Immediate) | Rehydrate & Eat healthy snack | Replenish lost minerals. |
Community Insights: What to Do Before and After Infrared Sauna Reddit Trends
Go through wellness forums, and you’ll find lots of anecdotal advice. In looking for what to do before and after an infrared sauna Reddit users often point to a few key “hacks” that seem to be in line with best advice from the experts:
- “The Sweat Continues”: Many Redditors emphasize that you shouldn’t wipe your sweat off during the session. Letting the sweat dry on your skin allows the body to reabsorb some of the antimicrobial peptides produced in the sweat, which is great for skin conditions like acne or eczema.
- Chromotherapy: Users will often talk about turning on the chromotherapy lights (color light therapy) that are an included feature in many saunas to boost mood.
- Reading Material: A common tip is to avoid bringing phones or electronics in to avoid EMF exposure (though quality saunas are low EMF) and to truly disconnect.
