The optimal infrared sauna clothing choice is minimal loose-fitting cotton garments, a swimsuit, or using the sauna nude in private settings. Research on heat transfer shows that clothing blocks 15-30% of infrared penetration depending on fabric thickness and type, potentially reducing therapeutic benefits. Cotton allows better infrared transmission than synthetic materials while absorbing sweat effectively. Most health studies showing sauna benefits used minimal clothing protocols, with participants wearing swimsuits or towels rather than full coverage. The primary considerations are maximizing infrared exposure to skin, maintaining comfort during sweating, preventing overheating, and ensuring appropriate hygiene. Safety factors include avoiding synthetic fabrics that can overheat, removing metal accessories that conduct heat excessively, and preventing restriction from tight elastic bands. Personal comfort, privacy preferences, and whether you're using a private home sauna versus shared facility all influence optimal clothing choices. What you wear significantly affects both immediate comfort and therapeutic effectiveness. Strategic clothing choices maximize benefits while maintaining safety and appropriate hygiene standards. Understanding Infrared Heat and Clothing Infrared saunas work differently than traditional Finnish saunas, which affects clothing considerations. Traditional saunas heat air to 160-200°F, making any clothing uncomfortable due to air temperature. Infrared saunas use radiant heat at lower air temperatures (130-150°F), directly warming your body through infrared wavelengths penetrating skin. Different infrared wavelengths penetrate to different depths. Near-infrared (700-1,400nm) penetrates 5-10mm into tissue, reaching superficial muscles. Mid-infrared (1,400-3,000nm) penetrates 2-3mm, primarily affecting skin and superficial tissue. Far-infrared (3,000-1,000,000nm) penetrates 1.5-2mm, primarily heating skin surface. Clothing creates a barrier between infrared emitters and your skin. The thicker and denser the fabric, the more infrared gets blocked or absorbed by the clothing itself rather than penetrating to your body. This matters because many therapeutic benefits depend on tissue heating at specific depths. Research measuring infrared transmission through fabrics shows: * Thin cotton: 70-85% transmission (blocks 15-30%) * Thick cotton: 50-70% transmission (blocks 30-50%) * Synthetic blends: 40-60% transmission (blocks 40-60%) * Heavy fabrics: 30-50% transmission (blocks 50-70%) This doesn't mean clothing eliminates benefits entirely. You still receive significant infrared exposure through light fabrics. However, maximum therapeutic effects occur with minimal fabric barriers. Best Clothing Options for Infrared Sauna Cotton Athletic Wear (Top Choice for Clothed Use) Loose-fitting cotton athletic shorts and a cotton tank top or t-shirt provide the best compromise between modesty and infrared transmission. Cotton breathes well, absorbs sweat effectively, and allows better infrared penetration than synthetic materials. Recommended: * Lightweight cotton shorts (loose fit, not compression) * Cotton tank top or lightweight t-shirt * Cotton sports bra for women (non-underwire) * Loose cotton boxer briefs for men if desired Why Cotton Works: Natural fibers allow better heat and moisture transfer than synthetics. Cotton doesn't trap heat against skin like polyester, reducing overheating risk. The material withstands repeated high-heat exposure without degrading or releasing chemical odors. Limitations: Cotton becomes heavy when saturated with sweat, which some people find uncomfortable. Wet cotton can feel cool against skin toward session end. The fabric blocks 15-30% of infrared depending on thickness. Swimsuits (Excellent Middle Ground) Swimsuits offer minimal coverage while maintaining modesty, making them ideal for shared saunas or when you prefer some clothing. They're designed for moisture and heat, making them practical for sweating environments. Best Swimsuit Choices: * One-piece swimsuits for women (simple styles without excessive fabric) * Bikinis for women comfortable with minimal coverage * Swim trunks or board shorts for men (loose fit preferred) * Athletic swimwear rather than fashion styles with metal embellishments Advantages: Minimal fabric means maximum infrared exposure (85-95% transmission). Designed to stay comfortable when wet. Easy to wash and quick-drying. Appropriate for most shared sauna settings. Considerations: Avoid swimsuits with metal clasps, underwire, or decorative elements that heat excessively. Choose solid colors over prints, as some dyes may run or fade from repeated heat exposure. Lycra/spandex content should be minimal, as these synthetics can overheat. Towel Wraps (Traditional Choice) Wrapping in a cotton towel provides adjustable coverage, allowing you to expose areas receiving red light therapy while maintaining modesty. Towel Protocol: * Use clean cotton towel (avoid synthetic microfiber) * Wrap loosely rather than tightly * Sit on additional towel to absorb sweat and protect sauna bench * Adjust position to expose areas needing maximum infrared exposure Benefits: Complete flexibility in coverage amount. Easy to adjust during sessions. Protects sauna surfaces from sweat. Traditional approach used in many cultures. Drawbacks: Towels can slip during movement or stretching. Some people find adjusting towels distracting during meditation or relaxation. Heavy absorption means towels become quite wet during sessions. Nude (Optimal for Maximum Benefits) Using infrared sauna nude provides maximum infrared exposure and allows complete freedom of movement. This is the most common choice for private home saunas where privacy isn't a concern. Why Nude is Optimal: * 100% infrared transmission with no fabric barriers * No fabric restrictions during stretching or movement * Eliminates laundry of dedicated sauna clothing * Most comfortable option for many people * Allows even sweating and heat distribution Hygiene Considerations: Always sit on a clean towel when using sauna nude. This protects both you and the sauna surfaces. Replace towel after each use. Shower before sauna sessions to minimize bacteria transfer. When Nude Makes Sense: Private home saunas used solo or with intimate partners. Settings where you're comfortable with nudity. Sessions focused on maximum therapeutic benefit rather than social interaction. Cultural Considerations: Nude sauna use is standard in Finnish, German, and some other European traditions. American culture tends toward swimsuits or light clothing. Choose based on personal comfort, not just optimal heat transfer. What NOT to Wear in Infrared Sauna Synthetic Fabrics (Polyester, Nylon, Spandex) Avoid synthetic athletic wear including polyester, nylon, spandex/Lycra, and synthetic blends commonly used in modern workout clothing. These materials create multiple problems in infrared sauna environments. Why Synthetics Are Problematic: * Poor breathability traps heat against skin, increasing overheating risk * Block 40-60% of infrared transmission * Can melt or deform at high temperatures * May release chemical odors when heated * Don't absorb sweat, leaving moisture on skin surface * Some synthetics may release microplastics when heated (research ongoing) Common Synthetic Items to Avoid: * Compression gear (Under Armour style) * Most modern athletic leggings * Tech-fabric workout shirts * Synthetic athletic shorts * Sports bras with high synthetic content If you own only synthetic athletic wear, prioritize getting at least basic cotton alternatives for sauna use. The performance benefits of synthetics for exercise become drawbacks in sauna environments. Tight or Restrictive Clothing Compression clothing, tight elastic waistbands, and restrictive garments cause multiple issues during sauna sessions. Problems with Tight Clothing: * Restricts circulation when blood vessels are trying to dilate for cooling * Creates pressure points that become increasingly uncomfortable as sessions progress * Limits breathing depth during relaxation exercises * Prevents effective sweating in covered areas * Can leave temporary marks or indentations from prolonged pressure during heat Even normally comfortable elastic waistbands become restrictive during 25-40 minute sessions as your body swells slightly from heat and increased blood flow. Metal Accessories and Jewelry Remove all metal jewelry, accessories, and items before entering infrared sauna. Metal conducts heat rapidly, creating burn risks or significant discomfort. Items to Remove: * All jewelry (rings, necklaces, bracelets, anklets) * Watches (both traditional and smart watches) * Belt buckles * Metal hair clips or pins * Underwire bras * Piercings (if removable) * Glasses with metal frames Why Metal is Problematic: Metal heats 10-50 times faster than skin depending on the metal type. Jewelry against skin becomes uncomfortably hot within 10-15 minutes. Rings can cause burns if not removed. Metal objects also interfere with even heat distribution by creating hot spots. Watches and Electronics: Heat and moisture damage electronic devices. Smart watches may overheat and malfunction. Moisture can penetrate watch seals. Leave all electronics outside the sauna. Makeup and Skincare Products Remove makeup before infrared sauna sessions. Heat causes makeup to run, clog pores, and interfere with sweating responses. Many cosmetic products contain ingredients that become irritating when heated. Why to Remove Makeup: * Clogs pores during heavy sweating * Can cause breakouts or irritation * Runs and becomes uncomfortable * Some products contain chemicals that may be problematic when heated * Interferes with skin benefits from infrared and red light exposure Enter sauna with clean, product-free skin for optimal benefits and comfort. Save skincare routines for after sessions when pores are open and receptive. Heavy Lotions or Oils Avoid applying lotions, oils, or heavy skincare products before sauna sessions. These create barriers on skin surface, interfere with sweating, and can create slipping hazards. Problems with Pre-Sauna Products: * Block pores and prevent effective sweating * Create uncomfortable greasy feeling during heat * Can drip off and make surfaces slippery * Interfere with infrared absorption at skin surface * Some products may heat excessively or create irritation If you prefer products on skin, apply after sauna sessions when pores are open and absorption is enhanced. Excessive Clothing Layers Some people mistakenly believe wearing multiple layers or heavy clothing will increase sweating and provide additional benefits. This is counterproductive and potentially dangerous. Why Layers Are Problematic: * Excessive insulation can cause dangerous overheating * Interferes with body's natural cooling responses * Blocks infrared from reaching skin * Creates extremely uncomfortable experience * May impair your ability to recognize overheating symptoms The goal is allowing your body to heat appropriately through infrared exposure, not artificially trapping heat with excessive clothing. If you want more intense sessions, slightly increase temperature or extend duration within safe limits, don't add clothing. Gender-Specific Considerations For Women Sports Bra Selection: Choose cotton or cotton-blend sports bras without underwire. Underwire bras become uncomfortable as metal heats and wires press against ribcage. Wireless sports bras or bralettes work better. Consider that many women find swimsuit tops or going topless (in private settings) most comfortable. Period Considerations: If menstruating, wear a tampon or menstrual cup rather than pads. Heat can make external pads uncomfortable and potentially increase bacterial growth. Change immediately after sessions. Some women find sauna use during menstruation helps with cramps and pain, though others prefer avoiding heat during their cycle. Pregnancy: Most experts recommend pregnant women avoid sauna use or use only very brief, cool sessions (under 100°F for 10-12 minutes maximum). If physician approves limited use, wear loose cotton clothing for easier exit if you become uncomfortable. Never use sauna nude during pregnancy if sharing space with others, maintaining appropriate boundaries. For Men Shorts vs. Towel: Loose cotton shorts or swim trunks work well. Athletic boxer briefs are acceptable if cotton and not compression style. Many men prefer using towel wraps or going nude in private settings. Fertility Considerations: Frequent heat exposure to the testicles may temporarily reduce sperm production. If actively trying to conceive, consider using sauna 2-3 times weekly rather than daily, and wear loose shorts rather than tight clothing to allow some heat dissipation. The effect is temporary and reverses after discontinuing frequent use. For Non-Binary and Gender-Diverse Individuals Choose whatever clothing feels comfortable and affirming. There's no single "correct" option. In private home saunas, you have complete freedom. In shared facilities, select what feels appropriate for your comfort and the setting. Some people alternate between different clothing choices based on mood or needs. Hygiene and Cleanliness Standards Regardless of what you wear, maintain excellent hygiene to protect both yourself and your sauna. Pre-Session Protocol: * Shower before entering sauna (removes dirt, bacteria, skin oils) * Use mild soap, rinse completely * Remove all makeup and skincare products * Dry off before entering (wet skin can inhibit initial sweating response) During Session: * Always sit or lie on a clean towel (never directly on sauna surfaces) * Keep clean towel under feet if resting them on benches * Avoid touching face with hands after touching surfaces Post-Session Protocol: * Shower to remove sweat and any released toxins * Wash all clothing/towels after each use * Clean sauna surfaces regularly per manufacturer instructions * Never reuse sweaty clothing for subsequent sessions Shared Sauna Etiquette: If using shared facilities, respect posted clothing requirements. Many shared saunas require swimsuits or specific coverage. Follow facility rules even if you'd prefer different options. Bring dedicated sauna towels that never touch gym floors or other surfaces. Temperature and Comfort Adjustments Clothing choices affect your comfort at different temperature settings. You may need to adjust either clothing or temperature based on preferences. At Lower Temperatures (125-135°F): Light cotton clothing or swimsuits remain comfortable throughout typical 30-40 minute sessions. This temperature range accommodates those preferring more coverage without excessive overheating. At Middle Temperatures (135-145°F): Minimal clothing (swimsuit or light cotton) works best. Full cotton t-shirts and shorts may feel too warm by 20-30 minutes. Many people prefer less coverage at these temperatures. At Higher Temperatures (145-155°F): Minimal coverage or nude use is most comfortable. Even light fabrics can feel excessive at higher temperatures. If wearing clothing at high temperatures, expect to need shorter session durations. Experiment to find your optimal temperature and clothing combination. Some people prefer nude at 140°F while others are comfortable in light cotton at 150°F. Individual variation is substantial. Clothing Care and Maintenance Sauna clothing requires more frequent washing than regular athletic wear due to salt and sweat saturation. Washing Recommendations: * Wash after every single use (never reuse sweaty sauna clothing) * Use hot water to kill bacteria * Add 1/2 cup white vinegar to remove salt deposits and odors * Avoid fabric softeners (reduce absorbency) * Air dry when possible (dryers can break down elastic over time) Maintaining Dedicated Sauna Wardrobe: Keep 3-4 cotton sauna outfits if using clothing regularly. This ensures clean options are always available and extends clothing lifespan by reducing washing frequency for individual items. When to Replace: Cotton sauna clothing typically lasts 6-12 months with regular use (3-5 sessions weekly) before losing absorbency or developing permanent odors. Swimsuits may last 8-15 months. Replace items showing signs of breakdown, permanent discoloration, or lingering odors after washing. Special Situations and Considerations Recovering from Injury or Surgery If you have bandages, surgical dressings, or braces, consult your physician before using sauna. Heat can affect healing in complex ways. If approved, keep dressings dry and minimal, ensuring areas receiving therapeutic benefit (like joint pain relief) are exposed to infrared when possible. Skin Conditions People with eczema, psoriasis, or other skin conditions may benefit from sauna but should avoid irritating fabrics. Cotton is typically least irritating. Some skin conditions improve with regular sauna use through reduced inflammation, but consult your dermatologist about clothing choices that minimize irritation. Tattoos New tattoos (less than 2-4 weeks old) should avoid sauna exposure entirely, including any clothing coverage. Once fully healed, tattoos are fine in sauna. Clothing doesn't provide meaningful protection to tattoos from infrared exposure. Private vs. Shared Sauna Considerations Private Home Sauna: Complete freedom in clothing choices. Most people use minimal clothing or nude for maximum benefits. Privacy allows optimizing for therapeutic effect rather than modesty. You can experiment with different options across sessions to find personal preferences. Shared Facility or Gym Sauna: Follow posted rules strictly. Most require swimsuits at minimum. Bring clean towel to sit on. Respect other users' comfort levels. Even if rules allow nudity, consider whether others present might prefer you wear swimsuit. Social considerations outweigh small therapeutic differences in shared settings. Couples or Family Use: Discuss clothing expectations before sessions. Establish household norms everyone is comfortable with. Different family members may have different preferences even in private home settings. Respect individual comfort levels rather than imposing single standard. Conclusion: Optimal Clothing Choices What Research and Practice Support ✓ ✓ Minimal cotton clothing: Allows 70-85% infrared transmission while maintaining modesty, good compromise for most users ✓ Swimsuits: 85-95% infrared transmission, appropriate for shared settings, comfortable when wet ✓ Nude use in private settings: 100% infrared transmission, maximum therapeutic benefit, no fabric restrictions ✓ Loose fit over tight: Allows circulation, breathing, and comfortable sweating throughout sessions ✓ Cotton over synthetics: Better breathability, moisture absorption, and infrared transmission What to Avoid in Sauna ✗ ✗ Synthetic fabrics: Block 40-60% of infrared, poor breathability, overheating risk ✗ Tight or restrictive clothing: Impairs circulation and comfort during extended sessions ✗ Metal jewelry and accessories: Becomes uncomfortably hot, creates burn risk ✗ Makeup and heavy skincare: Clogs pores, interferes with sweating and skin benefits ✗ Excessive layers: Creates dangerous overheating without additional benefits The Evidence-Based Verdict For maximum therapeutic benefit in private settings, minimal clothing or nude use provides optimal infrared exposure to skin. In shared settings or when personal comfort requires coverage, lightweight cotton clothing or swimsuits offer the best compromise between modesty and therapeutic effectiveness. The difference in benefits between nude and light cotton clothing is modest (15-30% increased infrared exposure nude), so choose based on comfort and setting rather than feeling pressured toward minimal clothing if that doesn't suit you. Avoiding synthetic fabrics, tight clothing, and metal accessories is more important than the specific minimal clothing option you choose. These problematic items create safety concerns or substantially reduce benefits regardless of other choices. Optimal Clothing Protocol Recap For Private Home Sauna (Solo Use): 1. First choice: Nude with clean towel to sit on 2. Second choice: Loose cotton shorts only (men) or cotton sports bra/shorts (women) 3.

Frequently Asked Questions Is it better to wear clothes in an infrared sauna or go naked? Nude use provides maximum therapeutic benefit with 100% infrared transmission to skin versus 70-85% transmission through light cotton clothing. The difference matters most for applications requiring deep tissue heating like pain relief or muscle recovery, and for maximizing red light therapy benefits where direct skin exposure is optimal. However, the 15-30% benefit difference is modest, so personal comfort should guide your choice. In private home saunas used solo, most people prefer nude for comfort, freedom of movement during stretching, and maximum benefit. When sharing sauna with partners or family, choose whatever everyone is comfortable with. In shared facilities, follow posted rules which typically require swimsuits. For beginners uncertain about nude use, start with light cotton clothing or swimsuits and experiment with less coverage as comfort increases. Individual comfort and consistency matter more than marginal therapeutic differences. Choose the option that makes sauna practice most sustainable long-term. Can I wear a bathing suit in an infrared sauna? Yes, swimsuits work excellently in infrared saunas and represent the most popular choice for shared facilities. Swimsuits provide 85-95% infrared transmission, only slightly less than nude use, while maintaining modesty. Choose simple one-piece suits or bikinis for women, swim trunks or board shorts for men. Avoid swimsuits with underwire, metal clasps, or excessive metal decorations as these heat uncomfortably. Athletic swimwear typically works better than fashion swimwear with embellishments. Select swimsuits with minimal Lycra/spandex content since synthetics can overheat. Simple, well-fitted swimwear designed for actual swimming rather than purely decorative styles performs best. Bring dedicated sauna swimsuits that you wash after every use rather than using your pool or beach swimsuits. The salt and heavy sweating require more frequent washing than typical swimsuit use. Many home sauna owners keep 2-3 simple swimsuits specifically for sauna to ensure clean options are always available. Swimsuits offer an excellent middle ground between maximum therapeutic exposure and appropriate coverage for most situations. What kind of towel should I bring to a sauna? Bring cotton towels rather than synthetic microfiber towels. Cotton absorbs sweat effectively, withstands high heat without issues, and allows better infrared transmission if wrapping around your body. You need at least one large towel to sit or lie on (never sit directly on sauna surfaces regardless of clothing choice), and optionally a second smaller towel for wiping face and body during sessions. Some people prefer bringing a third towel for wrapping if using towel instead of clothing. Choose medium-weight bath towels rather than heavy thick towels (better for wiping when saturated) or thin hand towels (insufficient coverage for sitting). White or light-colored towels show stains less obviously than dark towels, though you'll wash after every use anyway. Avoid beach towels with rubber backing or synthetic materials. Establish dedicated sauna towels separate from your regular bath towels, washing them after every single use with hot water and vinegar to remove salt deposits and prevent bacterial growth. Replace sauna towels every 6-12 months as they wear from frequent washing. Proper towel use maintains both hygiene and sauna surface protection regardless of whether you're wearing clothing, swimsuit, or using nude. Should I remove my wedding ring in the sauna? Yes, remove all rings including wedding rings before entering infrared sauna. Metal jewelry heats 10-50 times faster than skin, becoming uncomfortable or causing burns within 10-15 minutes of exposure. Wedding rings are particularly problematic because people forget they're wearing them until the ring is already uncomfortably hot. Gold, silver, platinum, and other metals all conduct heat rapidly. Rings also impair circulation slightly when fingers swell from heat, potentially causing temporary discomfort. Remove rings, watches, necklaces, bracelets, and all other jewelry before sessions. Keep a small dish or safe spot outside your sauna for jewelry storage. If you're uncomfortable removing your wedding ring in shared facility settings, at minimum move it to a finger where you'll remember to avoid touching heated surfaces. However, complete removal is safer. The habit of removing all jewelry before sauna becomes automatic after a few sessions. If you have piercings that are removable, take those out as well. Non-removable piercings (recently done or permanently installed) require extra caution about positioning to avoid contact with heated surfaces. Body modification jewelry can heat significantly, so be mindful of placement during sessions. Can I wear compression clothing in an infrared sauna? No, avoid compression clothing in infrared sauna for multiple reasons. Compression gear restricts circulation when your blood vessels are trying to dilate for cooling, creating discomfort and potentially impeding therapeutic benefits. The tight elastic becomes increasingly uncomfortable as 25-40 minute sessions progress, especially around waist, chest, and legs. Most compression clothing uses synthetic fabrics (polyester, nylon, spandex) that block 40-60% of infrared transmission, reducing therapeutic effectiveness. Synthetics also trap heat against skin, don't breathe well, and don't absorb sweat effectively. The performance benefits of compression gear for exercise become significant drawbacks in sauna environments. Compression clothing can leave temporary marks or indentations from prolonged pressure during heat when your body swells slightly from increased blood flow. Additionally, tight clothing restricts breathing depth if you're practicing breathing exercises or meditation during sessions. Choose loose-fitting cotton shorts and tops instead. If you only own compression athletic wear, invest in basic cotton alternatives specifically for sauna use. The difference in comfort and benefit is substantial enough to warrant dedicated sauna clothing. Is it OK to wear makeup in a sauna? No, remove all makeup before infrared sauna sessions for both comfort and skin health reasons. Heat causes makeup to run, melt, or become uncomfortably tacky within 5-10 minutes. Makeup clogs pores during heavy sweating, potentially causing breakouts or irritation. Many cosmetic products contain ingredients that may become irritating when heated to skin temperature during sessions. Foundation, powder, and other face makeup block pores where sweat needs to exit, interfering with your body's cooling responses. Eye makeup runs into eyes as you sweat, causing stinging or blurred vision. Mascara may flake. Lipstick melts or transfers to hands when you wipe face. Beyond immediate discomfort, makeup interferes with skin benefits from infrared and red light exposure. The therapeutic wavelengths work best on clean, product-free skin where light can penetrate without barriers. Remove makeup thoroughly before sessions using gentle cleanser, then enter sauna with completely clean face. Save your skincare routine for after sessions when pores are open and receptive to product absorption. Many people notice improved skin quality specifically from regular clean-faced sauna use allowing proper detoxification through facial sweating. Can I wear a sports bra in an infrared sauna? Yes, cotton or cotton-blend sports bras work well in infrared sauna if you prefer coverage. Avoid underwire bras as metal wires heat uncomfortably and press against ribcage. Choose wireless sports bras or bralettes in cotton or mostly-cotton blends. Avoid compression sports bras with high synthetic content (polyester, nylon, spandex) as these trap heat, don't breathe well, and block infrared transmission. Light-support cotton sports bras or simple cotton bralettes provide adequate coverage while allowing better infrared exposure than regular bras. The elastic band can become uncomfortable during longer sessions as your body swells slightly from heat, so choose bras with softer, wider bands rather than tight elastic. Many women find swimsuit tops more comfortable than sports bras since swimwear is designed for wet conditions. In private home sauna settings, many women prefer going topless, especially if working on muscle recovery or wanting maximum red light therapy exposure to chest and shoulder areas. Choose based on personal comfort and setting. If using sports bra, wash after every single use as sweat saturation requires immediate cleaning to prevent bacterial growth and odor development. What should I wear to an infrared sauna if I'm self-conscious about my body? Wear whatever makes you comfortable enough to maintain consistent practice, as comfort and sustainability matter more than marginal therapeutic differences. Light cotton t-shirt and loose cotton shorts provide good coverage while still allowing 70-85% infrared transmission. Women can wear cotton sports bra and cotton shorts, or a one-piece swimsuit for more coverage. Loose cotton athletic pants and top work if you prefer fuller coverage, though they become quite warm during sessions. A large cotton towel wrapped around your body provides adjustable coverage you can modify during sessions as comfort increases. Remember that in private home saunas, you're completely alone or only with chosen partners/family, eliminating concerns about strangers seeing you. Many people initially self-conscious about their bodies discover that the private, therapeutic context of sauna creates different feelings than public settings like gyms. Start with whatever coverage makes you comfortable. As you experience the benefits and become accustomed to sessions, you may naturally gravitate toward less clothing, but there's no pressure or timeline. Focus on establishing consistent practice first. Body confidence often improves as you experience the mental health benefits of regular sauna use, including stress reduction and improved body awareness. Your relationship with your body may shift positively through regular practice regardless of clothing choices.
