Walking into an infrared sauna is a choice to slow down, warm up, and reconnect with your body. Clothing might feel like a small detail, yet it shapes comfort, heat exposure, and how relaxed you feel during the session. Many people arrive unsure about what works best, what feels respectful in a shared space, and what allows the sauna to do what it does best.
At Altered States Wellness, guests often ask this question before their first session. A simple answer rarely covers all situations, since personal comfort, hygiene, and the sauna environment all matter. This guide offers clear, current guidance so each session feels easy, supportive, and unrushed.
Understanding How Infrared Saunas Interact With Clothing
Infrared saunas warm the body through light waves that penetrate the skin rather than heating the air aggressively. This difference changes how clothing behaves inside the sauna. Thick fabrics block infrared light, reducing direct skin exposure and limiting the warming effect many people seek.
Skin contact plays a role in how evenly warmth spreads across the body. Breathable materials allow heat to circulate without trapping moisture. Tight or synthetic fabrics tend to feel sticky and uncomfortable as perspiration increases. Comfort improves when clothing feels almost unnoticeable while sitting or stretching.
Awareness of how heat, sweat, and fabric interact helps guide smart clothing choices that feel supportive rather than distracting.
Minimal Clothing Versus Modest Coverage
Some people prefer minimal clothing or no clothing at all during a private infrared sauna session. This approach allows maximum skin exposure and unrestricted movement. Private rooms make this option straightforward for many users.
Shared or semi-private sauna environments often call for modest coverage. Comfort, respect for others, and facility guidelines shape this decision. Wearing light, breathable layers offers coverage without compromising heat absorption too much.
Personal comfort always leads the choice. Feeling self-conscious or restricted pulls attention away from relaxation. Clothing should support ease rather than create distraction.
Best Fabrics to Wear in an Infrared Sauna
Fabric choice matters more than style inside an infrared sauna. Natural fibers breathe better and feel gentler on warm skin.
Cotton remains a popular option due to softness and breath ability. Lightweight cotton shorts, loose tees, or simple wraps allow air flow and feel familiar. Bamboo fabric offers a similar feel with a slightly smoother texture and strong moisture management. Linen also works well, especially for wraps or loose garments, since it dries quickly and stays light.
Synthetic fabrics tend to trap heat and moisture. Materials designed for intense workouts often feel uncomfortable once sweat builds. Stretchy compression wear usually feels restrictive and can cause overheating in certain areas.
Choosing natural, loose-fitting fabrics supports comfort throughout the session.
Towels as a Simple and Effective Option
A towel serves multiple purposes in an infrared sauna. Wrapping a towel around the waist or body offers coverage while keeping fabric minimal. Sitting or lying on a towel also protects benches and maintains hygiene.
Large cotton towels feel soft against the skin and absorb moisture well. Many people prefer two towels, one for sitting and one for wrapping or wiping sweat. Towels allow easy adjustment during the session, giving flexibility to cool down or cover up as needed.
This option suits first-time users who want simplicity without overthinking clothing choices.
What to Wear on Your Lower Body
Lower body clothing should feel loose and breathable. Shorts made from cotton or bamboo allow airflow while providing coverage. Skirts or wraps also work well, especially for those who enjoy seated sessions without movement.

Avoid tight waistbands or heavy seams that may press into the skin as heat increases. Comfort improves when nothing digs into the body during long seated periods.
For users who enjoy gentle stretching or movement inside the sauna, looser garments allow natural motion without pulling or bunching.
What to Wear on Your Upper Body
Upper body options range from bare skin to light tops. Many people choose to go without a shirt in private sessions for full skin exposure. Others prefer loose tanks or tees for comfort or modesty.
Lightweight cotton or bamboo tops feel soft and breathable. Sleeveless options reduce fabric contact and help regulate temperature. Long sleeves usually feel unnecessary and may trap heat unless someone prefers extra coverage.
The goal centers on ease rather than fashion. Clothing should fade into the background while warmth does the work.
Footwear and Accessories Inside the Sauna
Bare feet work best in most infrared sauna settings. Feet stay cooler naturally and benefit from direct warmth without obstruction. Socks typically feel uncomfortable once sweat begins.
Jewelry should stay outside the sauna. Metal heats quickly and may feel irritating against warm skin. Watches, fitness trackers, and glasses also tend to fog or overheat.
Hair ties made from soft fabric feel more comfortable than elastic or metal clips. Keeping hair off the neck may improve comfort as body temperature rises.
What to Avoid Wearing in an Infrared Sauna
Certain clothing choices consistently cause discomfort. Heavy fabrics, thick athletic wear, and synthetic blends often trap heat and moisture. Compression garments restrict circulation and movement. Underwire bras or tight straps may press into the skin uncomfortably.
Swimsuits seem like an easy option, yet many contain synthetic fibers that feel sticky under heat. Chlorine residue from pools may also react unpleasantly with warmth.
Choosing simple, breathable options prevents distractions and allows full relaxation.
Dressing for Different Sauna Goals
Some people enter an infrared sauna with clear intentions. Relaxation, meditation, gentle stretching, or quiet reflection each carry slightly different clothing preferences.
Meditative sessions often feel best with minimal clothing or soft wraps that allow stillness without pressure. Stretching benefits from loose garments that move easily with the body. Shorter sessions focused on warmth may feel comfortable with towels alone.
Listening to personal needs guides clothing choices session by session.
Hygiene and Post-Sauna Clothing Considerations
Fresh clothing after a sauna session feels essential. Sweaty garments tend to cool quickly and may feel uncomfortable against damp skin. Packing clean, breathable clothes for afterward supports comfort during the transition back to normal temperature.
Showering before or after sessions depends on personal preference and facility guidelines. Wearing clean sauna clothing helps maintain a pleasant environment for everyone.
Simple planning ensures the sauna experience ends as smoothly as it begins.
Seasonal and Climate Factors
Outdoor temperature and season influence clothing choices. Colder months may inspire slightly more coverage when entering and exiting the sauna space. Warmer climates make minimal clothing feel natural.
Layering before and after sessions supports comfort without affecting the sauna experience itself. Inside the sauna, simplicity remains the guiding principle regardless of season.
Listening to Your Body Above All Else
Guidelines provide structure, yet personal comfort remains the most reliable guide. Bodies respond differently to heat, fabrics, and coverage. One session may feel perfect with a towel, another with light clothing.
Paying attention to how clothing feels during and after sessions builds awareness over time. Adjusting choices based on comfort, ease, and relaxation keeps the sauna experience supportive and enjoyable.
Final Thoughts
Clothing inside an infrared sauna should feel effortless. Breathable fabrics, loose fits, and minimal layers support comfort and allow warmth to flow naturally. Towels offer flexibility and simplicity, while natural fibers feel kind to warm skin.
Preparation helps remove uncertainty before stepping inside. Choosing the right attire allows attention to rest where it belongs, on stillness, warmth, and the quiet moments that make infrared sauna sessions so restorative.
