Adaty deriniň ýa-da bedendäki organlary we dokumalary ýeňil zeperlerden goramak üçin ýagtylygy siňdirmek ukyby bar. Lightagtylygyň adam dokumasynyň tolkunky uzynlygy we deri dokumalarynyň gurluşy bilen ýakyndan baglanyşyklydyr. Generally, the shorter the wavelength, the shallower the penetration into the skin. The skin tissue absorbs light with obvious selectivity. Mysal üçin, sapaklarda pererino keseli köp mukdarda pilkenli ululykdaky we bazal gatlakdaky uzyn gatlakdaky pöküpdirijileriň nahary ýok (tolkun uzynlygy 320 n m4m 400 m) ýalbarýan örtükleri siňdirip biler (tolkun uzynlygyna "tolkun uzynlygyndaky" gazy sanyň "-a siňdirilip bilner). The skin tissue absorbs different wavelengths of light differently, and most of the ultraviolet rays are absorbed by the epidermis. As the wavelength increases, the degree of penetration of light also changes. Infrared rays near the red light machine penetrate into the deepest layers of the skin, but are absorbed by the skin. The long-wave infrared (wavelength is 15~400μm) penetrates very poorly, and most of it is absorbed by the epidermis.
