Abanye abantu bayazibuza ukuthi imibhede yokushiswa kwesikhumba isebenzisa “ukukhanya kwelanga” noma ukuthi ilanga ngokwalo lisebenza ngendlela efanayo nombhede wokushiswa kwesikhumba. Impendulo ingucha — imibhede yokushiswa kwesikhumba ayisebenzisi ukukhanya kwelanga kwemvelo. Esikhundleni salokho, basebenzisa izibani zokwenziwa ze-ultraviolet (UV) ezenzelwe ukulingisa izingxenye ezithile zomsebe welanga.
1. Ukukhanya kwelanga vs. Ukukhanya kombhede we-Tanning
Ilanga: Likhiqiza ingxube yemvelo ye-UVA, i-UVB, nokukhanya okubonakalayo. Imisebe ye-UVB isiza umzimba ukuthi ukhiqize i-vitamin D, kuyilapho imisebe ye-UVA ingena ngokujulile esikhumbeni futhi ibangele ukushiswa kwesikhumba kanye nokuguga.
Imibhede Yokushiswa Kwelanga: Sebenzisa ama-bulb anamandla aphezulu akhipha imisebe ye-UVA kakhulu (cishe ama-95%) kanye nenani elincane le-UVB (cishe ama-5%). Le nhlanganisela inamandla futhi igxile kakhulu kunokukhanya kwelanga okuvamile.
