Red light therapy and infrared therapy are often mentioned together in the world of wellness, 스킨케어, and pain relief — and for good reason. They both use light energy to stimulate healing and regeneration in the body. But are they the same thing?
그것을 분해하자.
레드라이트 테라피란??
빨간불 치료 (RLT) uses visible red light wavelengths, 일반적으로 사이 620nm and 660nm. These wavelengths penetrate the skin to a shallow depth — around 8 에게 10 millimeters — and are known to:
- Stimulate 콜라겐 생산
- 개선하다 skin tone and texture
- Promote 상처 치유
- 줄이다 inflammation on the skin’s surface
- Aid in hair growth
Because red light is visible to the human eye, RLT often gives off a soft, warm red glow.
What Is Infrared Therapy?
Infrared therapy uses invisible light, specifically 근적외선 (근적외선) 파장, 일반적으로 사이 700nm and 1100nm. These wavelengths penetrate much deeper into the body — up to 5 centimeters (about 2 신장) — reaching 근육, 관절, 심지어 뼈까지.
Infrared therapy is commonly used to:
- Relieve joint and muscle pain
- Enhance circulation and oxygenation
- 줄이다 깊은 염증
- 지원하다 nerve regeneration and repair
- 개선하다 recovery after workouts or injury
Since NIR light is 보이지 않는, these devices won’t appear to glow as brightly as red light therapy panels, though they may still emit some warmth.
Key Differences Between Red and Infrared Therapy
| 특징 | 레드 라이트 테라피 | 적외선 요법 |
|---|---|---|
| 파장 | 620-660nm | 700–1100nm |
| 시계 | 보이는 (red glow) | Invisible |
| 침투 깊이 | ~10 mm (skin level) | 최대 50 mm (근, 관절, bone) |
| Primary Uses | 피부 건강, 노화 방지, hair growth | 통증 완화, 근육 회복, deep tissue healing |
| Sensation | Warm, glowing | Often no visible light, deeper warmth |
Can They Be Used Together?
Yes — and they often are.
Many modern red light therapy devices combine red and near-infrared wavelengths for maximum therapeutic benefit. This dual-wavelength approach allows the treatment of both surface-level 그리고 deep tissue issues in one session.
예를 들어:
- 660nm 빨간색 빛 can boost collagen for skin rejuvenation
- 850nm 근적외선 can reduce joint pain and inflammation deeper in the body
This combination is especially popular in full-body therapy beds and panels.
최종 생각
Red light therapy and infrared therapy are not exactly the same — but they’re closely related and often work best together. Red light targets surface skin concerns, while infrared goes deeper to relieve pain and support recovery. Whether you’re aiming for younger-looking skin or relief from sore muscles, understanding the difference helps you choose the right device — or combination — for your wellness goals.
