Whether you lie naked or clothed in a red light therapy (RLT) bed depends on your comfort level and treatment goals. Here’s what you need to know: 1. Naked vs. clothed: What’s more effective?
Naked (or minimal clothing):
Best for skin treatments (anti-aging, acne, psoriasis).
Red/NIR light penetrates directly without fabric blocking absorption.
Ideal for whole body benefits (e.g. collagen production, muscle recovery).
Clothing (lightweight fabrics):
Thin, white or light coloured clothing allows some light penetration.
Avoid thick/dark fabrics (they block light).
Good for privacy in common areas (spas, clinics).
2. What do most people do?
At home: Many go naked or wear underwear for maximum exposure.
In spas/clinics: Some facilities provide disposable underwear or allow minimal clothing.
For specific areas (face, joints): Clothing isn’t an issue if the area is exposed.
3. Hygiene & safety tips RLT beds don’t require goggles (unlike UV tanning).
Lay out a clean towel if using a shared bed.
Shower before/after if treating acne or open skin.
4. Exceptions (when to cover up) Private areas: If sensitive, wear white cotton underwear.
Tattoos: No risk, but some prefer to cover fresh ink to avoid heat.
Photosensitivity (rare): If on certain medications (e.g. Accutane), consult a doctor.
Final Verdict For best results: The more skin exposed, the better.
For comfort / modesty: Light, close-fitting clothing (such as a sports bra & shorts) works well.
