いいえ, red light therapy does not use ultraviolet (紫外線) ライト. 赤色光療法は使用します 目に見える赤い光 (typically around 630–660 nanometers) and sometimes 近赤外線 (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?
- 紫外線 (紫外線) ライト has much shorter wavelengths (100–400 nanometers) and is known for causing sunburn, skin aging, and increasing skin cancer risk with excessive exposure.
- 赤と近赤外光 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 not include UV rays, 赤色光療法:
- Does not tan the skin
- Does not damage DNA
- Is considered non-ionizing and safe for repeated use
実際には, red light therapy is used to repair sun damage and support healthy skin, the opposite of what UV light can do.
結論
赤色光療法 is not ultraviolet light. Instead, it uses safe red and near-infrared wavelengths to promote healing, 炎症を軽減する, and support skin and tissue health — without the risks associated with UV exposure.
