Last Updated on August 4, 2025

Ever stepped out of a sauna and felt more drained than detoxed? Well, a lot of first-time users end up overwhelmed, dehydrated, or wondering if they did something wrong.

But here’s the thing, infrared saunas aren’t like traditional steam rooms.

They work differently, feel different, and need a little more know-how to get the full benefits.

As a registered nurse and wellness and recovery consultant, I’ve guided clients through these small tweaks that make a massive difference.

If you’re looking for real, no-fluff guidance, you’re in the right place.

Let’s break it down into simple, smart infrared sauna tips for beginners so you walk out refreshed, not wrecked.

Why Infrared Saunas Are Different (And Why That Matters)

Not your average steam box.

When most people hear “sauna,” they think of a blazing hot wooden room filled with thick steam and burning eyeballs.

But infrared saunas? They flip the script entirely.

Instead of heating the air around you, infrared saunas use infrared light to warm your body directly.

This means you get that deep internal heat at lower, more tolerable air temperatures, typically between 110°F and 140°F.

The result? You sweat more, detox deeper, and feel less suffocated.

In fact, studies have shown infrared heat can penetrate up to 5 cm beneath the skin, compared to traditional saunas which mostly impact surface layers.

That means better circulation, enhanced muscle recovery, and improved skin health, with less strain on your cardiovascular system.

Here’s what this really means: infrared saunas are perfect for people who want the therapeutic benefits of heat without the oppressive air. They’re gentler, safer, and more effective when used right.

9 Best Infrared Sauna Tips For Beginners

Ready to unlock those benefits? Let’s make sure your sessions start the smart way.

1. First Timer? Start With Short Sessions

More time ≠ more benefits.

You don’t need a 45-minute sweat marathon to feel amazing. In fact, if it’s your first time, long sessions can backfire fast.

Infrared heat continues working even after you step out, so pushing past your limit can lead to dizziness, fatigue, or nausea.

Most experts, and personal experience with my own clients, agree that beginners should aim for 10 to 15 minutes, max.

Once your body adapts, you can gradually work up to 20–30 minutes per session.

And don’t worry about losing out.

A study found that moderate, repeated infrared sessions (about 3–4 per week) significantly improved vascular function, detoxification, and stress markers, even at shorter durations.

Let me ask you this: Have you ever felt completely wiped out after trying something “healthy”?

That’s a sign it was too much, too soon. In sauna therapy, slow is strong.

2. Pick The Right Temperature, Not The Highest

Hotter isn’t smarter.

Here’s a common mistake I see, cranking the temp to 150°F thinking it’ll boost results. But in reality, all it boosts is discomfort.

The ideal infrared sauna temperature for beginners is between 110°F and 125°F.

That may not sound intense, but trust me, you’ll still sweat buckets.

The key difference is you’re allowing your body to adjust gradually to infrared heat, rather than shocking your system.

There’s also research to back this up.

One study found that lower infrared temps paired with consistent use led to reduced muscle pain, better joint function, and enhanced sleep in adults with chronic fatigue, all without overexertion.

Let me ask: Is your skin turning blotchy or you’re overheating just five minutes in?

That’s your cue, dial it back. Sauna use should feel warm and deeply relaxing, not like you’re roasting alive.

3. Stay Hydrated Before And After (Don’t Skip This)

Dehydration ruins the whole experience.

It’s easy to underestimate just how much water your body loses during a sauna session.

But here’s the deal: even a mild 20-minute session can cause you to lose up to 1.5 liters of water

through sweating. If you’re not prepping your hydration before and after, you’re risking headaches, fatigue, muscle cramps, and ironically, fewer health benefits.

Start hydrating about 30–45 minutes before your session.

Plain water works, but if you’re doing longer sessions or frequent use, electrolyte-rich drinks are your best friend.

Coconut water, mineral water, or even a pinch of sea salt in your bottle helps replenish what you’re losing.

Post-session hydration is just as critical. Aim for at least 16–24 oz of fluids after your session, and don’t forget to pair it with a light snack, something with potassium and sodium like a banana and almonds works well.

Let me ask: Do you often feel sluggish or light-headed after your session?

That’s your sign right there, your body’s telling you it needs more water. Hydration isn’t optional in infrared sauna use. It’s the foundation.

4. Know What To Wear (Or Not Wear) Inside

Less is more.

Let’s make this simple: your skin needs to breathe, and your body needs to sweat.

What you wear in the sauna can make or break that process.

For most people, the best choice is a clean towel, just wrap it around and go.

If that’s not comfortable or your setting isn’t private, opt for loose, breathable cotton.

Anything too tight, synthetic, or moisture-trapping will block sweat and may cause irritation or even heat rash.

Leave the jewelry outside. Metal heats up fast in infrared light, and that necklace or bracelet you forgot to remove? It could burn.

Quick test:
Do you feel itchy, restless, or hot spots on your skin during your session? That’s often a reaction to the wrong fabric or too much coverage.

If you’re at home, embrace the comfort. Go minimal. The more your skin can release heat and toxins, the better your body responds to the therapy.

5. Prep Your Skin, And Don’t Forget The Aftercare

Glowing skin starts before the sauna.

Most people think saunas are just a “hop in, hop out” situation. But your skin? It plays a huge role in how effective that session will be.

Before your sauna, cleanse your face and body with warm water, skip harsh scrubs, but do remove any makeup, lotion, or sunscreen.

These block pores and trap sweat, reducing your skin’s natural detox ability.

Once or twice a week, gently exfoliate before your session. This helps slough off dead skin and boosts that post-sauna glow.

Now for the often-skipped part: aftercare.

Right after your session, rinse off with lukewarm water (avoid cold showers unless you’re seasoned) and use a light, nourishing moisturizer with hyaluronic acid or ceramides.

This seals in hydration and keeps your skin barrier happy.

What this really means is that your skin is one of your biggest detox organs. Treat it like part of the therapy, not just the surface getting sweaty.

Ask yourself: Does your skin feel dull or dry after your sessions? If yes, it’s not the sauna’s fault, it’s the prep and aftercare routine that needs tweaking.

6. Be Consistent, Not Intense

Small steps, big wins.

Infrared sauna benefits don’t come from that one 40-minute sweat marathon you barely survived.

They come from showing up consistently, even if it’s just 15 minutes a few times a week.

Here’s something most beginners don’t realize: your body adapts and responds over time.

Another study found that consistent low-heat infrared sessions led to measurable improvements in cardiovascular health, pain relief, and mood regulation.

These effects were strongest in participants who used the sauna 3 to 4 times a week, not daily or in long bursts.

Your takeaway? Create a routine that fits into your life. After a workout. Before bed. First thing in the morning with your tea.

What matters more than duration is frequency and rhythm.

Let me ask you something: Are you pushing for faster results, then skipping sessions because you’re too exhausted?

That’s a classic beginner pitfall. Go lighter. Show up more often. That’s where the magic happens.

7. Create A Relaxing Environment That Feeds The Mind Too

Your sauna is your sanctuary.

Here’s a question we don’t ask enough: What are you doing in there while you’re sweating it out?

Because yes, your surroundings affect your outcome, not just the heat.

If you’re scrolling social media or mentally replaying your to-do list, you’re not getting the full benefit. Your nervous system needs calm for the deep healing to kick in.

So here’s what I recommend to clients and use myself:

Dim the lights or use soft amber bulbs.
Add calming essential oils like eucalyptus, lavender, or frankincense.
Play ambient music or a meditation track, not your workout playlist.
Leave your phone outside unless it’s your music source (even then, silence notifications).

Why does this matter? Because saunas aren’t just physical detox, they’re mental reset rooms.

Multiple studies now link infrared heat therapy to improved mood, reduced anxiety, and lower cortisol levels.

But only if you let your mind participate in the pause.

Let me ask: Is your mind racing while your body’s trying to relax? That disconnect is a lost opportunity. Set the tone. Make it yours.

8. Track How You Feel After Each Session

Your body’s feedback is gold.

If you’re not paying attention to how you feel after each session, you’re missing a chance to fine-tune everything.

I always encourage my clients to keep a sauna journal, nothing fancy. Just a few notes after every session:

How long was the session?
What temperature did you set?
How did you feel physically and emotionally afterward?
Did you sleep better that night?
Any skin changes?

What this does is help you recognize patterns. Maybe 125°F feels great, but 135°F leaves you dizzy. Maybe 20 minutes is perfect, but 30 makes your energy crash.

This is how you build your ideal sauna protocol, not just copy someone else’s.

One client told me she didn’t realize her Sunday night sessions helped her fall asleep faster, until she looked back at her notes. Now it’s her weekly ritual.

So, are you just winging it every time? A little reflection goes a long way. Your body knows what works, it’s just waiting for you to listen.

9. Know When To Skip A Session

More isn’t always better, especially if your body’s waving a red flag.

Listen, there’s a difference between mild detox fatigue and your body screaming for rest. And beginners often blur that line.

Here are a few signs it might be time to skip a session:

You’re already dehydrated or haven’t eaten in hours
You’re feeling lightheaded, overly fatigued, or nauseous
You’re coming down with a cold or fighting inflammation
You’re pregnant, on certain medications, or have specific medical conditions (always consult your doctor!)

Infrared sauna therapy is powerful. But it’s not a “push through no matter what” kind of thing.

In fact, overuse can backfire, raising cortisol, weakening immunity, and disrupting sleep.

Here’s something I tell every new client:

Missing a sauna day isn’t failure. It’s feedback.

If your body needs rest, honor that. It’s part of the wellness process.

Final Thoughts – It’s Your Journey, Not A Race

If you’ve made it this far, you’re not just curious, you’re ready.

Infrared saunas aren’t about sweating, they’re about slowing down, tuning in, and reconnecting with your body’s natural rhythm.

And in a world that rarely encourages that? It’s a small rebellion with massive healing potential.

Here’s a quick recap of what you’ve learned:

Start low and slow, both in heat and time
Hydration and electrolytes are non-negotiable
Make post-sauna recovery part of the routine
Create a space that calms your mind, not just your muscles
Track your experience, your body speaks in patterns
Be consistent, not intense
And most importantly, know when to rest

Every session is a chance to reset, recharge, and realign. You don’t need to get it perfect. You just need to start.
