Kubantu abaningi, impendulo yombuzo wokuthi kungenzeka yini ukukhipha ingilazi kusobala. Yiqiniso, "cha", iningi likholwa, futhi umuntu kufanele avume, liphutha kakhulu. Cha, eqinisweni, baphikisana neqiniso lokuthi abashayeli nalabo abasebenza ezindaweni zabo eziseduze nefasitela, ukushisa kwelanga kubonakala ngokushesha, akukho muntu ozokwenza. Kodwa i-physics yale nqubo ayilula njengoba ingase ibonakale.
Uhlobo lokushisa kwelanga
Ukuze uphendule umbuzo wokuthi kungenzeka yini ukuthola i-sunburnt ngeglasi elivamile ebhaleni noma emotweni, eqinisweni, wonke umuntu angayenza eyedwa - lokhu akudingekile ukuba nemfundo ekhethekile. Into eyinhloko ukuqonda ngokucacile indlela inqubo yokunyamala kwesikhumba eyenzeka ngayo, futhi yiziphi izici ezithinta.
Noma iyiphi i-ray ye-solar inezinhlobo eziningana ezahlukene zemisebe yombane. Ngamunye wabo ubonakala ngendlela yakhe: ezinye zibhekwa njengomthombo wokushisa, ezinye zikhanya kuphela. Yiqiniso, akekho okwazi ukuzwa i-ultraviolet noma ayithinte ngezandla zabo.
Kunezinhlobo ezintathu eziyinhloko zemisebe ye-UV:
- Umshini ubude besikhathi eside. Lifinyelela ngokuphelele emhlabeni jikelele futhi lithinta umzimba ngokungacabangi. Ama-ray alula ukungena emigqeni ejulile ye-epidermis. Ngenxa yalokho okushiwo yikudala okusheshayo kunalokho okubekiwe. I-radiation ibhubhisa i-collagen kanye ne-dehydrate amaseli esikhumba. Ngaphansi kwethonya layo, ukubomvu okuncane kungase kuvele. Abanye abantu ngenxa yalo baqala ukungezwani kwelanga . Kodwa uma ziboshelwe ngamagagasi amade, ngeke zibeke izingozi zezempilo.
- Ukukhuluma ukuthi kungenzeka yini ukugqoka ingilazi yefasitela, kubalulekile ukukhumbula ukukhanya kwe-B. Kuyinto emfushane-wave, kodwa lokhu akuvimbeli it kusuka cishe ngokuphelele eMhlabeni - ngisho nangenxa yokuthi lapho ukushayela nezithiyo, amagagasi unendawo yokuhlakaza. Ama-ray-umthombo we- tan esheshayo . Ngaphansi kwethonya labo, i-melanocytes iveza melanin ngokushesha kakhulu. Kodwa uma uxhumana nabo isikhathi eside kakhulu, isikhumba singashisa.
- Into eyingozi kakhulu imisebe ye-gamma. Ngenhlanhla, iningi lemisindo yalo lilindile endleleni eya eMhlabeni ngobunqamu be-ozone. Ngaphandle kwalokho, zonke izinto eziphilayo emhlabeni zizovele zishiswe.
Kuzo zonke ezingenhla, singakwazi ukuphetha isiphetho esisodwa: ukuze wenze ngokushesha, ngokulinganayo nangaphezulu kakhulu, usadinga ukuxhumana okuqondile nama-UV emisebe.
Ngingayithola yini ngefasitela lemoto noma amafasitela?
I-Glass - into ebonakalayo. Ilula kalula kalula, kodwa iphuza imisebe ye-ultraviolet ye-beta nehlobo le-gamma. Imisebe ye-Alpha, ngisho namafasitela amakhulu kakhulu angeke ayeke. Futhi njengoba usuyazi kakade, ama-ray a-long-ray ama-ray e-epidermis anethonya elincane kakhulu. Umthelela omkhulu ongaphumelela ukubuyiswa kancane kwesendlalelo esingaphezulu kwesikhumba, okuyinto
Ukuthungula okuhle ngefasitela noma ingilazi yemoto kungenzeka kuphela uma kutholakala izimo eziningana. Okokuqala, imisebe yelanga kufanele isebenze njalo ku-epidermis. Okwesibili, umthunzi we-chocolat uzovela ngamathuba aphezulu uma isikhumba sine-melanin. Incazelo ichaza: ngokuhamba kwesikhathi, i-tan iyahlanzwa iphiswe. Kodwa ama-melanocytes, lapho exhumana ngokuqondile nelanga, akhiqiza inani elikhulu le-melanin. Futhi manje ngisho nangaphansi komthelela wemisebe yesikhulu esingabalulekile isikhumba se-epidermis singaqala ukunyamalala.
