Red light therapy and infrared therapy are often mentioned together in the world of wellness, त्वचा की देखभाल, 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?
आइए इसे तोड़ें.
रेड लाइट थेरेपी क्या है??
लाल प्रकाश चिकित्सा (आरएलटी) उपयोग दृश्यमान लाल प्रकाश तरंग दैर्ध्य, आम तौर पर बीच में 620एनएम और 660 एनएम. These wavelengths penetrate the skin to a shallow depth — around 8 को 10 millimeters — and are known to:
- Stimulate कोलेजन उत्पादन
- Improve skin tone and texture
- Promote घाव भरने
- Reduce 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 निकटवर्ती (निर) तरंग दैर्ध्य, आम तौर पर बीच में 700nm and 1100nm. These wavelengths penetrate much deeper into the body — up to 5 centimeters (के बारे में 2 इंच) — reaching मांसपेशी, जोड़, and even bones.
Infrared therapy is commonly used to:
- Relieve joint and muscle pain
- Enhance circulation and oxygenation
- Reduce deep inflammation
- सहायता nerve regeneration and repair
- Improve recovery after workouts or injury
Since NIR light is अदृश्य, 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
| विशेषता | लाल प्रकाश चिकित्सा | इन्फ्रारेड थेरेपी |
|---|---|---|
| वेवलेंथ | 620-660nm | 700–1100nm |
| दृश्यता | दृश्यमान (red glow) | Invisible |
| प्रवेश गहराई | ~10 mm (skin level) | तक 50 मिमी (माँसपेशियाँ, joint, bone) |
| Primary Uses | त्वचा का स्वास्थ्य, बुढ़ापा विरोधी, hair growth | दर्द निवारक, मांसपेशियों की रिकवरी, गहन ऊतक उपचार |
| 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 सतह-स्तर और deep tissue issues in one session.
उदाहरण के लिए:
- 660एनएम लाल बत्ती can boost collagen for skin rejuvenation
- 850nm near-infrared light can reduce joint pain and inflammation deeper in the body
This combination is especially popular in full-body therapy beds and panels.
Final Thoughts
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.
