What Should I Wear in an Infrared Sauna? Complete Clothing Guide

What Should I Wear in an Infrared Sauna? Quick Answer

Wear as little clean, lightweight, and breathable clothing as you feel comfortable wearing. In a private home sauna, many people use only a towel or a loose wrap. In a public sauna, a lightweight swimsuit, loose cotton shorts, or modest breathable clothing is usually the safest choice. Always follow the facility’s dress code and place a clean towel between your body and the bench.

Best options: a towel, lightweight swimsuit, loose cotton shorts, breathable underwear, or a cotton sauna wrap.

Avoid: sauna suits, waist trainers, neoprene belts, plastic or rubberized clothing, heavy workout clothes, tight compression garments, metal jewelry, and electronics.

Key Takeaways

• Choose minimal, loose, and breathable coverage for an infrared sauna session.
• Always sit or lie on a clean towel to protect the bench and improve hygiene.
• A clean swimsuit is acceptable when required by a gym, spa, or shared facility.
• Change out of damp workout clothes before entering the sauna.
• Remove metal jewelry, watches, fitness trackers, and unnecessary electronics.
• Do not use extra layers or plastic clothing to force more sweating.
• Leave the sauna and cool down if you experience dizziness, nausea, weakness, confusion, or unusual discomfort.

Does Clothing Affect How an Infrared Sauna Works?

Clothing does not turn infrared heat on or off, but it can change how comfortable the session feels. Infrared energy transfers heat to the body, while your body responds by increasing skin temperature and sweating. Heavy, tight, or non-breathable clothing can hold moisture against the skin and make it harder to release heat comfortably.

You do not need special clothing to make an infrared sauna effective. The goal is not to trap as much heat as possible. The better approach is to wear minimal, clean coverage that allows you to sit comfortably and end the session without feeling excessively overheated.

There is limited research comparing individual sauna outfits. Most clothing recommendations are based on heat management, hygiene, manufacturer guidance, and shared-sauna etiquette rather than evidence that one specific outfit produces greater wellness benefits.

Bottom line: Wear less, not more. Minimal breathable coverage lets the session feel comfortable and lets your body manage heat the way it is designed to.

What Are the Best Things to Wear in an Infrared Sauna?

The best sauna attire is simple, clean, loose, and appropriate for the setting. The following options cover most private and public sauna situations.

A Clean Cotton Towel

A clean towel is the most useful item to bring. Place it beneath your entire body before sitting or lying down. In a private sauna, you may also use a second towel as a wrap if you prefer minimal coverage.

A Lightweight Swimsuit

A swimsuit is a practical option in gyms, spas, hotels, and other shared facilities. Choose a clean, comfortable design without large metal fasteners, heavy padding, or restrictive straps.

Loose Cotton Shorts

Loose cotton shorts offer coverage without feeling as restrictive as tight gym clothing. Use a clean pair reserved for sauna or relaxation rather than the same shorts worn during a workout.

Lightweight Cotton Underwear

Clean, breathable underwear can be suitable in a private sauna or where facility rules allow it. Avoid tight elastic, underwire, or metal hardware that may become uncomfortable.

A Breathable Sauna Wrap or Cover-Up

A lightweight cotton or linen wrap can provide coverage while remaining easy to remove after the session. Avoid thick robes inside the sauna because they can become heavy and uncomfortable as they absorb sweat.

Minimal Clothing in a Private Sauna

In a private home sauna, minimal clothing or towel-only use is often the most comfortable option. The important part is to protect the bench with a clean towel and clean the sauna according to the manufacturer’s instructions.

Can You Go Nude in an Infrared Sauna?

You can use a private infrared sauna without clothing when you are comfortable doing so and no facility rule prohibits it. Minimal coverage keeps fabric from holding sweat against your skin and allows you to relax without restrictive clothing.

Always place a clean towel between your body and the wooden bench. In a public or shared sauna, check the posted dress code before entering. Cultural expectations and facility rules vary, so nudity may be accepted in some settings and prohibited in others.

Can You Wear a Swimsuit in an Infrared Sauna?

Yes. A clean swimsuit is one of the most common choices for a public infrared sauna. It provides coverage and is easy to pack in a gym or spa bag.

For better comfort, select a lightweight swimsuit that is not excessively tight and does not contain large metal clasps, decorative hardware, or thick padding. After the session, change out of the damp swimsuit instead of wearing it through the entire cooling period.

Are Cotton Clothes Good for an Infrared Sauna?

Lightweight cotton can be a comfortable choice because it is soft, familiar, and less restrictive than many tight synthetic garments. Loose cotton shorts, breathable underwear, and thin cotton wraps are generally better options than thick street clothes.

Cotton also absorbs sweat, which means heavy cotton items can become wet, clingy, and uncomfortable. Avoid hoodies, sweatpants, thick T-shirts, and heavy robes inside the sauna. When choosing cotton clothing, keep it lightweight and loose.

What Should Women Wear in an Infrared Sauna?

Women can choose a swimsuit, loose shorts, lightweight underwear, a sports bra without metal hardware, a cotton wrap, or only a towel in a private sauna. The best option depends on privacy, facility rules, and personal comfort.

Swimsuit or Bikini

A simple swimsuit or bikini is suitable for a shared facility. Avoid designs with large metal rings, clasps, underwire, or heavy padding.

Sports Bra and Loose Shorts

A clean sports bra and loose shorts can work when the clothing is lightweight and not strongly compressive. Change out of the same garments worn during exercise before beginning the sauna session.

Cotton Wrap or Towel

A cotton wrap or large towel provides adjustable coverage and is often comfortable for private sauna use.

Loose Cotton Clothing

Where more coverage is preferred, use a lightweight cotton top and loose shorts. Skip leggings, shaping garments, waist trainers, and tightly fitted layers.

What Should Men Wear in an Infrared Sauna?

Men commonly wear swim trunks, loose cotton shorts, lightweight underwear, a towel, or minimal clothing in a private sauna. Choose clean clothing with a relaxed fit and avoid wearing the same damp shorts used during a workout.

Swim Trunks

Lightweight swim trunks are practical in public or shared saunas. Avoid heavy board shorts with thick liners, large zippers, or metal details.

Loose Cotton Shorts

Loose cotton shorts provide modest coverage and allow more airflow than compression shorts or tight athletic clothing.

Lightweight Underwear

Breathable underwear may be appropriate in a private setting or where facility rules permit it. Use a clean pair and sit on a towel.

Towel or Sauna Wrap

A towel or lightweight wrap is one of the simplest options for a home sauna because it provides coverage without unnecessary layers.

What Should You Not Wear in an Infrared Sauna?

Avoid anything designed to trap heat, force extra sweating, restrict movement, or add unnecessary weight during the session.

Sauna Suits and Plastic Clothing

Do not wear plastic sauna suits, garbage-bag-style layers, or rubberized garments. These materials reduce heat loss and can make overheating and dehydration more likely.

Neoprene Belts and Waist Trainers

Neoprene belts and waist trainers hold heat against a small area and can feel restrictive as body temperature rises. They do not create targeted fat loss, and the additional sweating mainly represents temporary fluid loss rather than lasting change. For a clear breakdown of what sauna use actually does and does not do for body composition, read our guide on whether saunas help you lose weight.

Tight Compression Clothing

Compression shirts, leggings, and shorts can cling to the skin as they absorb moisture. Looser clothing is generally more comfortable during passive heat exposure.

Heavy Workout Clothes

Hoodies, sweatpants, jackets, thick socks, and layered gym outfits can become soaked and uncomfortable. More clothing does not automatically make a sauna session more effective.

Dirty or Sweaty Gym Clothes

Change after exercise before entering the sauna. Fresh clothing and a clean towel help reduce odor and prevent sweat, body oils, and dirt from being transferred to the bench.

Clothing With Metal Fasteners

Avoid clothing with large metal zippers, buckles, clasps, underwire, or decorative hardware. Metal components can become uncomfortably warm.

Thick Robes and Heavy Layers

A robe is useful before and after the session, but a thick robe inside the sauna can hold moisture and trap unnecessary heat. Leave it outside and use a towel or lighter wrap instead.

Can You Wear Workout Clothes in an Infrared Sauna?

You can wear clean, lightweight workout clothing, but it is usually better to change out of the damp clothes worn during exercise. Sweat-soaked leggings, compression shorts, sports bras, and shirts can cling to your skin and may make the session feel hotter and less hygienic.

For post-workout use, keep a separate swimsuit, loose shorts, or cotton wrap in your gym bag. Bring a clean towel for the bench and another towel for drying off. Our guide to using a sauna after the gym explains how to plan the rest of your post-exercise routine, including session timing and how to cool down properly afterward.

Should You Wear Shoes or Socks in an Infrared Sauna?

Most people use an infrared sauna barefoot, but public-facility rules vary. Shower sandals or flip-flops may be helpful in locker rooms and wet areas, yet many facilities require users to remove them before stepping onto the sauna floor or bench.

Do not wear outdoor shoes inside the sauna. Avoid thick socks unless a medical or facility-specific reason requires them. Clean sauna slippers may be acceptable when the facility permits them and they are reserved only for indoor use.

Should You Remove Jewelry, Watches, and Electronics?

Remove necklaces, rings, bracelets, watches, fitness trackers, and other metal accessories before the session. They can become uncomfortable as the surrounding temperature and your skin temperature rise.

Leave phones, earbuds, and other electronics outside unless the device manufacturer explicitly confirms that the product can tolerate the sauna’s temperature and humidity range. Water resistance does not necessarily mean heat resistance, and bringing electronics into the sauna can also distract from relaxation.

Why Should You Always Bring a Towel Into an Infrared Sauna?

A towel creates a clean barrier between your body and the bench. This protects the wood from sweat and body oils, improves comfort, and supports better etiquette in a shared facility.

For the most practical setup, bring two towels:

• Bench towel: large enough to fit beneath every part of your body that touches the bench.
• Drying towel: used to wipe sweat during the session or dry off afterward.

Do not use a towel that was already placed on a gym floor, used during exercise, or left damp in a bag.

What Should You Wear in a Public Infrared Sauna?

In a gym, spa, hotel, wellness center, or shared residential facility, begin with the posted dress code. A clean swimsuit, loose shorts, or modest breathable clothing is usually the most reliable option. Always use a towel on the bench, keep personal items organized, and avoid entering in sweaty workout clothes.

If you manage a commercial wellness space, gym, or hotel that includes infrared sauna facilities, our team at Sauna Steam Center handles commercial sauna installation for hotels, gyms, and wellness facilities across South Florida.

Public infrared sauna etiquette usually includes:

• Following the facility’s clothing and footwear rules
• Using a clean towel beneath your body
• Keeping conversation and device use to a minimum
• Avoiding fragrances, lotions, and oils that may bother other users or affect the sauna surfaces
• Leaving enough personal space for other guests

What Should You Wear in a Home Infrared Sauna?

A home infrared sauna gives you more privacy and control over clothing, cleaning, and session timing. You can wear a towel, a lightweight wrap, loose shorts, underwear, a swimsuit, or no clothing when that is comfortable for you.

Even in a private sauna, use a clean bench towel and follow the manufacturer’s cleaning instructions. A consistent setup can make regular use easier. Keep towels, drinking water, and loose post-sauna clothing near the unit so everything is ready before you begin.

What Should You Wear Before and After an Infrared Sauna?

What to Wear Before Your Session

Arrive in clothing that is easy to remove and change. Loose gym clothes, a robe, sandals, or casual clothing are convenient before the session, but they do not all need to go inside the sauna.

What to Wear During Your Session

Use minimal, breathable coverage and a clean towel. Choose clothing based on privacy, comfort, and facility rules rather than trying to maximize sweating.

What to Wear After Your Session

Change into clean, loose, dry clothing after cooling down and drying off. Avoid remaining in a wet swimsuit or sweat-soaked clothing because it can feel uncomfortable and may irritate sensitive skin. Some users combine their sauna session with a cold shower or contrast routine afterward. If that interests you, our guide to sauna and cold plunge benefits covers how to structure that routine safely.

How Should You Prepare for Your First Infrared Sauna Session?

1. Check the facility’s clothing, towel, and footwear rules.
2. Bring a clean swimsuit, loose shorts, wrap, or other lightweight coverage.
3. Pack one large towel for the bench and a second towel for drying.
4. Remove jewelry, watches, fitness trackers, and unnecessary electronics.
5. Change out of damp workout clothing before entering.
6. Have water available and avoid beginning the session when already dehydrated.
7. Start conservatively and leave immediately if you feel dizzy, nauseated, weak, confused, faint, or unusually uncomfortable.
8. Have clean, loose clothing ready for the cooling period afterward.

Infrared Sauna Clothing Tips for Sensitive Skin

People with sensitive skin may feel more comfortable in loose, soft clothing washed with a fragrance-free detergent. Avoid rough fabrics, tight elastic, heavily scented fabric products, and clothing that remains wet against the skin.

Use a clean towel and change into dry clothing after the session. Stop using the sauna if you develop unusual burning, significant irritation, hives, or another concerning skin reaction. Persistent or severe symptoms should be evaluated by a healthcare professional.

Infrared Sauna Clothing and Safety Tips

Clothing should never be used to force a more intense sauna session. Extra layers, plastic materials, sauna suits, and waist trainers can reduce heat loss without creating a proven increase in sauna benefits.

• Enter the sauna with clean, dry clothing or a clean towel.
• Do not use alcohol before or during a sauna session.
• Do not remain in the sauna to complete a target time when you feel unwell.
• Leave and cool down if you experience dizziness, nausea, headache, weakness, faintness, confusion, chest discomfort, or difficulty breathing.
• Ask a qualified healthcare professional before sauna use if you are pregnant, have a significant medical condition, take medication that affects blood pressure or heat tolerance, or have been told to limit heat exposure.

Dehydration is one of the primary concerns associated with sauna use, and heat-related illness can include symptoms such as dizziness, nausea, weakness, and confusion.¹²

Infrared Sauna vs. Traditional Sauna: Do You Wear the Same Thing?

Clothing recommendations are similar for both sauna types. Infrared saunas generally operate with lower air temperatures, while traditional saunas primarily heat the surrounding air to a higher temperature. In either environment, minimal breathable coverage and a clean bench towel are sensible choices.
