नहीं, red light therapy does नहीं use ultraviolet (यूवी) रोशनी. Red light therapy uses visible red light (typically around 630–660 nanometers) and sometimes near-infrared light (around 800–850 nanometers), which are both on the opposite side of the light spectrum from ultraviolet.
What’s the Difference Between Red Light and UV Light?
- Ultraviolet (यूवी) रोशनी has much shorter wavelengths (100–400 nanometers) and is known for causing sunburn, skin aging, and increasing skin cancer risk with excessive exposure.
- Red and near-infrared light have longer wavelengths, which penetrate the skin more gently and stimulate cell energy production without causing DNA damage.
Why Is Red Light Therapy Safe?
Because it does नहीं include UV rays, लाल प्रकाश चिकित्सा:
- Does नहीं tan the skin
- Does नहीं damage DNA
- Is considered non-ionizing and safe for repeated use
वास्तव में, red light therapy is used to repair sun damage and support healthy skin, the opposite of what UV light can do.
निष्कर्ष
लाल प्रकाश चिकित्सा is not ultraviolet light. Instead, it uses safe red and near-infrared wavelengths to promote healing, सूजन कम करना, and support skin and tissue health — without the risks associated with UV exposure.
