Kubantu abaninzi, impendulo yombuzo wokuba ingaba yenzeke ukuba idayini ibonakale. Ewe, "hayi", ininzi inkholelwa, kwaye umntu kufuneka avume, uyiphutha kakhulu. Hayi, ewe, ukuphikisana nenyaniso yokuba abaqhubi kunye nalabo abasebenza kuyo basondele kufuphi nefestile, ukushona kwelanga kubonakala ngokukhawuleza, akukho mntu uya kuyenza. Kodwa i-physics yale nkqubo ayiyinto elula njengoko ibonakala ngathi.
Ubume bokushisa ilanga
Ukuze uphendule umbuzo wokuba unako ukufumana i-sunburnt ngeglasi eqhelekileyo kwibhalkoni okanye kwimoto, eqinisweni, wonke umntu unokukwenza ngokwabo-kuba akuyimfuneko ukuba ibe nemfundo ekhethekileyo. Into ephambili ukuqonda ngokucacileyo indlela inkqubo yokwenyuka kwesikhumba eyenzeka ngayo, kwaye ziziphi izinto ezichaphazelayo.
Naluphina i-ray ray iqukethe iintlobo ezahlukeneyo zemitha ye-electromagnetic. Ngamnye wabo uqondwa ngendlela yawo: ezinye zibonwa njengomthombo wokushisa, ezinye zizodwa ngokukhanya. Ngokuqinisekileyo, akukho mntu unokukwazi ukuva i-ultraviolet okanye ukuyichukumisa ngezandla.
Kukho iintlobo ezintathu eziphambili ze-UV ray:
- Umbane udevelength eside. Ingena ephasini lomhlaba iphantse ngokupheleleyo kwaye ichaphazela umzimba ngokungaqondi. Ii-ray zilula ukungena kwiindawo ezinzulu ze-epidermis. Ngenxa yoko oku kudala kukudala kunokukhawuleza. I-radiation ibhubhisa i-collagen kunye ne-dehydrates iiseli zesikhumba. Ngaphantsi kwempembelelo yalo, uboya obomvu bubonakala. Abanye abantu ngenxa yalo baqala ukunyuka kwelanga . Kodwa ukuba bahlanjululwe ngamaza amade, abayi kuba neengozi zempilo.
- Ukuthetha malunga nokuba kunokwenzeka ukuba usebenzise ingilazi yefestile, kubalulekile ukukhumbula i-B-ray. Ingqungqutshane, kodwa oku akukuthinteli ukuba ifikelele ngokupheleleyo kwiLizwe - nangona ebonakalayo yokuba xa uhamba kunye nemingcipheko, amagagasi anepropati. I-B-ray - umthombo we- fast tan . Ngaphantsi kwefuthe labo, i-melanocytes ivelisa i-melanin ngokukhawuleza. Kodwa ukuba udibanisa nabo ixesha elide, isikhumba sitshisa.
- Eyona yingozi kakhulu i-gamma radiation. Ngethamsanqa, ininzi yemibala yayo ilibazisekile kwindlela eya kumhlaba ngobuncwane be-ozone. Ngaphandle koko, zonke izinto eziphilayo emhlabeni ziya kutshabalalisa.
Kuzo zonke ezi ngasentla, sinokwenza isigqibo esisodwa: ukuze ukhawuleze, ulungele ngakumbi kwaye ulunge ngakumbi, usadinga ukunxibelelana ngqo kunye ne-UV ray.
Ngaba ndinako ukwenza i window okanye iifestile?
I-Glass - izinto ezibonakalayo. Ilula ngokukhawuleza, kodwa ilibaziseka imitha ye-beta ye-beta kunye nohlobo lwe-gamma. Izaziso ze-Alpha, kunye neefestile ezinzima kunako ukuyeka. Kwaye njengoko sele uwaziyo, i-ray-long-long-long-ray e-epidermis inefuthe elide kakhulu. Isiphumo esiphezulu esinokufezekiswa ngokukhawuleza kwendawo ephezulu yesikhumba, leyo
Ukucola kakuhle ngefestile okanye kwiglasi yemoto kunokwenzeka kuphela ukuba kukho iimeko ezininzi. Okokuqala, imisebe yelanga kufuneka isebenze rhoqo kwi-epidermis. Okwesibini, umthunzi we-chocolate uza kubonakala unokwenzeka kakhulu xa ulusu lune-melanin. Inkcazo ilula: emva kwexesha, i-tan iyahlanjululwa kwaye isatshiswa. Kodwa i-melanocytes, ngexesha lokuqhagamshelana ngqo nelanga, lavelisa inani elikhulu le-melanin. Kwaye ngoku nangaphantsi kweempembelelo zemizila ebalulekileyo yesikhumba se-epidermis sinokuqala ukumnyama.
