The short answer: いいえ, you don’t have to undress completely, but maximizing skin exposure enhances results. Here’s a detailed guide to help you decide:
- How Clothing Affects Red Light Therapy
Bare Skin = Best Absorption
Red and near-infrared (nir) light penetrates skin best when unobstructed.
Clothing (especially thick fabrics like denim or polyester) can block or scatter light, reducing effectiveness.
Thin, Light-Colored Clothing = Partial Benefit
If modesty is a concern, white cotton or spandex (例えば, workout gear) allows some light through.
Avoid dark/black fabrics—they absorb light instead of letting it pass.
Nude vs. Covered Studies
研究 (例えば, ある 2017 Journal of Photomedicine study) shows direct skin exposure yields 30–50% better results for collagen production and wound healing.
- When to Undress vs. Stay Clothed
Undress for Maximum Benefits If Targeting:
✅ Wrinkles, 傷跡, or stretch marks (例えば, abdomen, thighs, chest).
✅ Muscle/joint pain (例えば, 戻る, knees, shoulders).
✅ Acne or psoriasis (light must reach affected skin directly).
You Can Stay Partially Clothed If:
✅ Using RLT for mood/circadian rhythm (eyes and face exposure matter most).
✅ Wearing minimal, light-colored clothing (例えば, sports bra + shorts).
✅ In a public or shared setting (many clinics provide disposable underwear/gowns).
- What About Underwear or Swimsuits?
Opt for minimal coverage:
Men: Briefs or boxers (avoid thick seams).
Women: Bikini or nude-toned underwear (dark colors block light).
Swimsuits work but may leave tan lines.
- Eye Protection & Accessories
目: Always wear protective goggles (red light is bright but not UV-damaging).
Jewelry: Remove metal pieces (they can reflect light unevenly).
- What to Expect in Public/Clinic Sessions
Most professional RLT beds (例えば, at spas or dermatology clinics) allow privacy with options like:
Disposable underwear.
Private changing rooms.
Gowns for partial coverage.
No nudity required—the staff will guide you based on treatment goals.
- At-Home vs. Professional Use
Setting Clothing Suggestions
At Home Nude or minimal clothing for best results.
Spa/Clinic Follow facility guidelines (often provided coverings).
Final Recommendations
For skin/hair benefits: Expose target areas bare (例えば, face, arms, legs).
For general wellness: Light clothing is fine if full nudity isn’t comfortable.
Always protect eyes and avoid dark fabrics.
Pro Tip: If covering up, apply aloe vera gel or a light serum beforehand—it enhances light penetration!
