Njengoba amazinga okushisa omhlaba wonke eqhubeka ekhula ngenxa yokushintsha kwesimo sezulu, amandla emisebe ye-ultraviolet (UV) efinyelela ebusweni bomhlaba abe yinto ekhathazayo kakhulu kubantu ngabanye kanye nezinhlangano ngokufanayo. Ukuchayeka isikhathi eside emisebeni ye-UV kungaholela ezinhlobonhlobo zezinkinga zezempilo, kusukela ekuqedweni kwesikhumba ngaphambi kwesikhathi kuya ezimweni ezibi kakhulu ezinjengomdlavuza wesikhumba, okwenza ukuvikelwa elangeni kube yinto ebalulekile kwezempilo yomphakathi. Ukubaluleka kokuqalisa izindlela ezisebenzayo zokuvikela ilanga akunakugcizelelwa ngokweqile, njengoba izigidi zabantu emhlabeni wonke zihlushwa ukulimala kwesikhumba okubangelwa imisebe ye-UV unyaka ngamunye, ngezindleko ezinkulu zezomnotho nezomuntu siqu. Ezinkampanini ezisebenzisa ukunyathelisa nokupakisha, ukuqonda ukuvikelwa kwe-UV nakho kubalulekile ekuqinisekiseni ukuthi amalebula emikhiqizo nezinto zokupakisha zigcina ubuqotho nokubukeka kwazo lapho zichayeke elangeni, ngaleyo ndlela kulondolozwa ikhwalithi yomkhiqizo nokwethenjwa kwamakhasimende. Izinkampani ezinjengeGurongprint (Shanghai) Co., Ltd., ezigxile ezixazululweni zokunyathelisa ezenziwe ngokwezifiso, ziyakubona ukubaluleka kwezinto ezingamelana ne-UV ekulethweni kwemikhiqizo eqinile nekhwalithi ephezulu kumakhasimende azo, futhi lobu uchwepheshe busiza izinkampani ekuvikeleni imikhiqizo yazo kanye namakhasimende azo. Lesi sihloko sihlose ukunikeza umbono obanzi wezindlela zokuvikela i-UV, sisiza abantu ngabanye nezinhlangano ukuthi benze izinqumo ezinolwazi mayelana nokuvikela isikhumba sabo nezinto zabo emisebeni eyingozi ye-UV ngenkathi kuthuthukiswa impilo yesikhathi eside nokusimama.

Ukuvikela ilanga akusiyona nje indaba yobuhle kodwa kuyingxenye eyisisekelo yokugcina impilo enhle nokuphila kahle, njengoba odokotela besikhumba begcizelela indima yako ekuvimbeleni izinhlobonhlobo zezimo zesikhumba. Imiphumela elimazayo yemisebe ye-UV iyaqongeleleka, okusho ukuthi ukuchayeka ngaphandle kokuvikeleka ngakunye kwengeza engcupheni yesikhathi eside yokuthola izifo ezihlobene nesikhumba njenge-actinic keratosis, ukushwabana ngaphambi kwesikhathi, kanye ne-melanoma, okugcizelela isidingo semikhuba yokuvikela engaguquki. Ukuqonda izinhlobo ezahlukene zemisebe ye-UV nokuthi zisebenzisana kanjani nesikhumba yisinyathelo sokuqala sokwamukela izindlela zokuvikela eziphumelelayo, futhi lolu lwazi lunika amandla abantu ukuthi bakhethe imikhiqizo nokuziphatha okufanele ezidingweni zabo ezithile. Ngaphezu kwalokho, amabhizinisi afaka ubuchwepheshe bokuvimbela i-UV emikhiqizweni yawo angakwazi ukunikeza inani elengeziwe kumakhasimende awo ngenkathi ebonisa ukuzibophezela empilweni nasekuphepheni, okuthuthukisa isithunzi somkhiqizo nokwethembeka kwamakhasimende ezimakethe ezinokuncintisana. Ngokuhlanganisa ulwazi lokuvikela ilanga kuzo zombili izinqubo zokunakekela umzimba kanye nezenzo zobungcweti, singakha isiko lokuqwashisa elibeka phambili impilo yesikhathi eside kunokulula kwesikhathi esifushane, ekugcineni kunciphisa umthwalo womhlaba wonke wezifo ezibangelwa i-UV. Lesi sihloko sizohlola izindlela ezahlukene zokuvikela ilanga, sichaze amanga avamile, futhi sinikeze amasu asebenzisekayo okuzivikela ngempumelelo ku-UV, kusetshenziswa ucwaningo lwesayensi kanye nezinqubo ezinhle zemboni.

Ukuvikela elangeni kuhlanganisa izinqubo eziningi, imikhiqizo, nobuchwepheshe obuklanyelwe ukuvikela isikhumba emiphumeleni eyingozi yemisebe ye-ultraviolet ekhishwa yilanga, okuseyizingozi ezinkulu kakhulu zemvelo empilweni yesikhumba emhlabeni wonke. Izinhlobo ezimbili eziyinhloko zemisebe ye-UV ezithinta isikhumba yi-UVA ne-UVB, ngayinye inamaza obude ahlukile, ukujula kokungena, nemiphumela yezempilo edinga izindlela zokuvikela ezikhethekile. Imisebe ye-UVA ingena ngokujula ku-dermis, ungqimba olukhulu kakhulu lwesikhumba, futhi iyimbangela enkulu yokuguga ngaphambi kwesikhathi, okuhlanganisa imibimbi, ukulahlekelwa ukunwebeka, namabala elanga, kuyilapho futhi inomthelela ekukhuleni komdlavuza wesikhumba ngokuhamba kwesikhathi. Imisebe ye-UVB, ngakolunye uhlangothi, iqondise ezingqimbeni ezingaphezulu zesikhumba futhi iyimbangela enkulu yokushiswa yilanga nokulimala kwe-DNA okuqondile, okungaholela ku-basal cell carcinoma, squamous cell carcinoma, ne-melanoma uma ukuvezwa kuphindaphindwa futhi kungavikelwanga. Ukuvikela elangeni okuphumelelayo kudinga indlela ebanzi ebhekana nokuvezwa kwe-UVA ne-UVB, kusetshenziswa amathuluzi nemikhiqizo eklanyelwe ukuvimba noma ukumunca le misebe eyingozi ngaphambi kokuba ilimaze amangqamuzana. Ngokuqonda isayensi ngemva kwemisebe ye-UV nemiphumela yayo kubhayoloji yomuntu, abantu bangenza izinqumo ezinolwazi ngemikhuba yabo yokuvikela elangeni futhi banciphise kakhulu ubungozi bokulimala kwesikhumba empilweni yabo yonke.

Ukuvikelwa okuqinile kubhekisela ezithiyweni ezibonakalayo ezivimbela imisebe ye-UV ukuthi ingafinyeleli esikhunjeni, zinikeze umugqa wokuqala wokuzivikela onokwethenjelwa emelene nemisebe yelanga ongancikile ekuphenduleni kwamakhemikhali noma ekufakweni kabusha komsebenzisi. Izibonelo zokuvikelwa okuqinile zihlanganisa ukugqoka izingubo ezinemikhono emide ezenziwe ngezindwangu ezilukwe ngokuqinile, ukusebenzisa izigqoko ezinomphempe abanzi ukuvikela ubuso, izindlebe, nentamo, kanye nokuthwala izambulela ezivikela i-UV ezivimbela iphesenti elikhulu lokukhanya kwe-ultraviolet ngokusebenzisa izinto ezikhethekile zokumboza nokuluka okuminyene. Lezi zindlela ezibonakalayo zisebenza ngempumelelo ngoba zinikeza ukumbozwa okungaguquki ngesikhathi semisebenzi yangaphandle ende efana nokuhamba izintaba, ukulima engadini, noma umsebenzi wokwakha, futhi zifanele abantu abanesikhumba esizwelayo okungenzeka basabele kuma-sunscreen amakhemikhali. Ezinkampanini ezinjengeGurongprint (Shanghai) Co., Ltd., ezinikeza izixazululo zokuphrinta nokupakisha ngendlela ekhethekile, ukufaka izinto zokumboza ezivikela i-UV kanye nama-laminate emikhiqizweni yazo kuqinisekisa ukuthi amalebula, amaphakheji, nezinto zokukhangisa zigcina ukugqama kwemibala yazo, ukufundeka, nokuqina kwesakhiwo ngisho nangemva kokuchayeka isikhathi eside elangeni emashalofini ezitolo noma ngesikhathi zithuthwa. Izindlela zokuvikelwa okuqinile nazo zivumelana nemvelo, ngoba zikhiqiza imfucuza encane uma ziqhathaniswa nezitsha zikagesi ezilahlwayo zama-sunscreen, zinciphisa isidingo sokuthenga imikhiqizo njalo, futhi zingasetshenziswa kabusha unomphela ngokunakekelwa okufanele. Ngokuhlanganisa ukuvikelwa okuqinile nezinye izinyathelo zokuphepha elangeni njengokuhlela imisebenzi yangaphandle ngaphandle kwamahora aphezulu e-UV, abantu nezinkampani bangazuza ukuvikelwa okuphelele kwe-UV okunciphisa izingozi zempilo futhi kugcine ikhwalithi yezinto kusikhathi eside.

Ukuzivikela okuthambile, ngakolunye uhlangothi, kuhilela ukusetshenziswa kwemikhiqizo esekelwe kumakhemikhali noma amaminerali amunca, ahlakaze, noma abonise imisebe ye-UV ngaphambi kokuba ingene esikhunjeni, inikeza ukuvikelwa okuguquguqukayo nokulula ezinhlobonhlobo zezikhumba nezimo zansuku zonke. Ama-sunscreen, ama-lotion, ama-spray, nezinti eziqukethe izithako ezifana ne-zinc oxide, i-titanium dioxide, i-avobenzone, noma i-octocrylene zingaphansi kwalesi sigaba, ngasinye salesi sithako sinikeza ubude bemisebe ethile bokuvikela okuhlangene kwakha ukuvikelwa okubanzi. Ukusebenza kwemikhiqizo yokuvikela ethambile kulinganiswa nge-SPF (Sun Protection Factor) yayo, ekhombisa izinga lokuvikelwa emisebeni ye-UVB nesikhathi eseluliwe ngaphambi kokuba ilanga lishise, kanye ne-PA (Protection Grade of UVA) yayo, ekala ukuvikelwa kwe-UVA esikalini ukusuka ku-PA+ kuya ku-PA++++. Lapho ukhetha i-sunscreen, kubalulekile ukukhetha umkhiqizo onikeza ukuvikelwa okubanzi, okusho ukuthi uvikeleka kuyo yomibili imisebe ye-UVA ne-UVB, ukuze uqinisekise ukuvikelwa okuphelele okubhekana nobungozi bombala wesikhumba obusheshayo nobude besikhathi. Ukuvikelwa okuthambile kufaneleka ukusetshenziswa nsuku zonke, ikakhulukazi ezindaweni zesikhumba okunzima ukuzimboza ngezingubo noma izinsimbi, njengezandla, ubuso, nentamo, futhi kungafakwa kalula ezinqubweni zasekuseni zokunakekela isikhumba ngaphandle kokuchitha isikhathi esiningi. Nokho, kubalulekile ukukhumbula ukuthi ukuvikelwa okuthambile kudinga ukusetshenziswa okufanele ngamanani anele nokuphindwa njalo emahoreni amabili ukuze kugcinwe ukusebenza kwakho, okwenza kube isu elihambisanayo elisebenza kahle kakhulu kanye nezindlela zokuvikela eziqinile.

Ukukhetha izithiyo ezibonakalayo ezifanele kubalulekile ekukhuliseni ukuvikelwa elangeni ngesikhathi semisebenzi yangaphandle nezinkambiso zansuku zonke, futhi ukuqonda izici zethuluzi ngalinye kusiza abathengi ukuthi benze izinqumo zokuthenga ezinolwazi. Lapho ukhetha isambulela sokuvikela emisebeni ye-UV, bheka imikhiqizo ekhonjiswe ngokucacile njengevikelayo ku-UV, enokulukwa okuqinile, nengaphakathi elimnyama lokunciphisa imisebe ye-UV ebonakalayo evela emhlabathini, kanye nobubanzi obukhulu ngokwanele ukwenza umthunzi omkhulu phezu komzimba ongenhla. Izigqoko ezinomphempe ababanzi, okufanele zibe okungenani amaintshi amathathu nxazonke, zinikeza ukuvikelwa okuhle ebusweni, ezindlebeni, nasentanyeni, okuyizindawo ezivame ukulimala ilanga, futhi izinto eziphefumulayo ezifana nokotini, utshani, noma izindwangu zokusebenza zisiza ukugcina ukunethezeka nokugeleza komoya esimweni sezulu esishisayo. Izingubo ezenziwe ngezindwangu ezikhethekile ezifana nenayiloni, ipholiyesta, noma izingxube ezinamakhemikhali amunca i-UV zinikeza ukuvikelwa okuthuthukisiwe, kanti ezinye izingubo zinomlinganiselo we-Ultraviolet Protection Factor (UPF) ovumela abathengi ukuthi baqhathanise amazinga okuvikelwa kalula phakathi kwemikhiqizo nemiklamo ehlukahlukene. Ezinkampanini ezisebenza emkhakheni wokuphrinta nokupakisha, ukusebenzisa kayinki evikelayo emisebeni ye-UV, amalaminethi, nezinto ezingaphansi kumalebula omkhiqizo akugcini nje ngokuvikela ipakisha ekupheleni, ekuqhekekeni, noma ekuphuzi, kodwa futhi kuqinisekisa ukuthi ulwazi olubalulekile olufana nezinsuku zokuphelelwa isikhathi nohlu lwezithako luhlala lufundeka kubathengi kuso sonke isikhathi sokuphila komkhiqizo. Ngokutshala imali kumathuluzi okuvikela asezingeni eliphezulu nokuqinisekisa izakhiwo zawo zokuvimba i-UV ngezitifiketi noma ukuhlolwa okuzimele, bobabili abantu ngabanye nezinkampani banganciphisa kakhulu ukuchayeka ku-UV nezingozi ezihambisana nakho ngenkathi bejabulela izinzuzo zesikhathi esichithwa ngaphandle. Ukuze uthole imininingwane ethe xaxa mayelana nokuzibophezela kwethu kwekhwalithi nezixazululo eziqinile, ungafunda mayelana nathi.Inkampani umlando nobungcweti.

Ukuqonda izinkomba ezibalulekile ezihlobene nemikhiqizo ye-sunscreen kubalulekile ekukhetheni izinga elifanele lokuvikeleka ngokuya ngohlobo lwesikhumba sakho, indlela ophila ngayo, kanye namaphethini ajwayelekile okuchayeka elangeni unyaka wonke. Inombolo ye-SPF ibonisa ukuthi i-sunscreen izovikela isikhumba isikhathi esingakanani emisebeni ye-UVB uma iqhathaniswa nesikhumba esingavikelekile; ngokwesibonelo, i-SPF 30 ivimba cishe amaphesenti angu-97 emisebe ye-UVB, kuyilapho i-SPF 50 ivimba cishe amaphesenti angu-98, kodwa ayikho i-sunscreen enikeza ukuvikeleka okungu-100 ekhulwini kungakhathaliseki isilinganiso. Isilinganiso se-PA, esimelwe izimpawu zokuhlanganisa (PA+, PA++, PA+++, noma PA++++), silinganisa izinga lokuvikeleka kwe-UVA, lapho izimpawu eziningi zokuhlanganisa zibonisa ukuvikeleka okukhulu ekugugeni kwesikhumba okubangelwa ukukhanya kwelanga, ukucekelwa phansi kwe-collagen, kanye nomonakalo wesikhathi eside wamaseli oqongelelana emashumini eminyaka. Ngokusetshenziswa kwansuku zonke, odokotela besikhumba bavame ukuncoma i-broad-spectrum sunscreen enokungenani i-SPF 30 kanye nesilinganiso se-PA esingu-PA+++ noma ngaphezulu, isetshenziswe ngobuningi ezindaweni eziveziwe zesikhumba kuhlanganise nezindawo ezivame ukunganakwa njengezindlebe, ingemuva lentamo, kanye nezingaphezulu zezinyawo. Kubalulekile ukufaka i-sunscreen imizuzu engu-15 kuya kwengu-30 ngaphambi kokuchayeka elangeni ukuze izithako zibophe kahle ku-stratum corneum, futhi ukuphinda kufakwe kufanele kwenzeke njalo emahoreni amabili noma ngokushesha ngemva kokubhukuda, ukujuluka kakhulu, noma ukuzisula ngetawula ukuze kugcinwe ukuvikeleka okungaguquki. Ngokufaka i-sunscreen enqubweni yabo yansuku zonke yokunakekela isikhumba njengesinyathelo esingaxoxiswani, abantu bangagcina ukuvikeleka okungaguquki kuyo yomibili imisebe ye-UVA ne-UVB, banciphise kakhulu umonakalo oqongelelanayo oholela ekugugeni isikhumba ngaphambi kwesikhathi, ukuguquka kombala wesikhumba, kanye nomdlavuza wesikhumba esikhathini sokuphila.

Ukukhetha i-sunscreen ngokuya ngohlobo lwesikhumba kuyinto ebalulekile ekuqinisekiseni ukunethezeka nokusebenza kahle ezinqubweni zokuvikelwa elangeni, ngoba ukwakheka okungalungile kungadala ukuthi umuntu angayisebenzisi njalo noma kubangele ukusabela okungekuhle. Kulabo abanesikhumba esinamafutha noma esivuthwa kalula, i-sunscreen engenawo amafutha, engeyona i-comedogenic, ene-gel, esekelwe emanzini, noma ene-matte finish iyona ekahle ngoba inikeza ukuvikelwa okuqinile ngaphandle kokuvimba izimbotshana zesikhumba, ukwandisa ubumpetha, noma ukushiya ukunamathisela okunamafutha okungakhululekile emini. Labo abanesikhumba esomile noma esizwela kakhulu kufanele babheke ama-sunscreen aqukethe izithako ezimanzi njenge-hyaluronic acid, i-glycerin, i-niacinamide, noma ama-ceramides, kanye nama-mineral blockers afana ne-zinc oxide noma i-titanium dioxide, ahlala phezu kwesikhumba futhi mancane amathuba okuthi abangele ukuluma, ubomvu, noma ukusabela okungokwe-alamu uma kuqhathaniswa nama-chemical filters. Izinhlobo zesikhumba esixubile zizuzisa kuma-formula alula, ane-broad-spectrum, alinganisa ukumanzisa ngaphandle kokuzwa esindayo noma okunamafutha endaweni ye-T-zone, kanti abasubathi, abasebenzi bangaphandle, noma abahambi njalo bangathanda ama-sunscreen amelana namanzi, amelana nokujuluka, agcina ukusebenza kahle ngesikhathi somzimba usebenza noma ezimweni ezinomswakama. Lapho kukhethwa i-sunscreen yezingane, abantu asebekhulile, noma labo abanesikhumba esonakele, ama-physical (mineral) sunscreens avame ukunconywa ngoba anikeza ukuvikelwa ngokushesha lapho efakwa, anengozi ephansi yokucasula, futhi mancane amathuba okuthi amuncwe egazini. Ngokufanisa izici ze-sunscreen nezidingo nezintandokazi zesikhumba somuntu ngamunye, abasebenzisi banamathuba amaningi kakhulu okuthi bayisebenzise ngokungaguquki, ngamanani anele, futhi njengomkhuba wansuku zonke, ngaleyo ndlela bakhulise izinzuzo zokuvikelwa futhi banciphise izingozi zezempilo zesikhathi eside ezihlobene nokuchayeka emisebeni ye-UV.

Enye yezinkolelo ezigcwele futhi eziyingozi kakhulu mayelana nokuvikelwa elangeni ukuthi i-sunscreen ayidingekile uma isibhakabhaka sigcwele amafu noma kumafu, kodwa le nkolelo ingaholela ekuchayekeni emisebeni ye-UV enkulu nokulimala kwesikhumba noma ngabe ilanga lingabonakali ngokusobala. Kuze kufike kumaphesenti angu-80 emisebe ye-UV engangena ngaphesheya kwamafu, okusho ukuthi noma ngabe ngosuku olumpunga, olunamafu, isikhumba sakho sisengozini yokushiswa yilanga, ukuguga kwesikhumba, nokulimala kwe-DNA okuqongelelana ngokuchayeka ngakunye okungavikelwe. I-UV index, ekala amandla emisebe ye-UV ngesikhathi esithile nendawo ethile ngesilinganiso esisuka ku-0 kuye ku-11 noma ngaphezulu, ivamise ukuhlala iphakathi nendawo kuya phezulu noma ngabe kukhona amafu, futhi ukuhlola le index ngohlelo lwezulu noma amawebhusayithi kungasiza ekuqondiseni izinqumo zakho zokuvikelwa elangeni usuku lonke. Iqhwa, isihlabathi, amanzi, nokhonkolo nakho kungakhombisa imisebe ye-UV, kwandise ukuchayeka noma ngabe kusemthunzini noma kunamafu ngokugxumela imisebe esikhumbeni isuka ngezansi, yingakho abashushumbisi, abahamba olwandle, nabathanda ukuba ngaphandle bedinga ukuqapha kakhulu noma ngabe isimo sezulu sithini. Ukuthembela emthethweni wokuthi "akukho sunscreen" ngezinsuku ezinamafu kunganaki ubunjalo bokuqongelelana kokulimala kwe-UV futhi kunciphisa ukwakheka kwemikhuba engaguquki yokuvikelwa elangeni ebalulekile empilweni yesikhumba eside. Umkhuba ongcono kakhulu uwukwenza ukufaka i-sunscreen kube umkhuba wansuku zonke noma ngabe isimo sezulu sithini, isizini, noma imisebenzi ehleliwe, uqinisekisa ukuthi isikhumba sakho sihlala sivikelwe emisebeni ye-UV eyingozi nokuthi awuke ulahlekelwe usuku lokuvikelwa ngenxa yezinkomba zezulu ezidukisayo.

Umqondo wokuthi ukugcoba uvikela elangeni kanye ekuseni kusempondweni kwanike usuku lonke ukuvikelwa kungumbono oyingozi oshiye isikhumba sengozini yomonakalo we-UV emahoreni ambalwa nje, ikakhulukazi ngesikhathi semisebenzi yangaphandle ende noma ngezikhathi eziphakeme zelanga. Izithako zokuvikela ilanga ziyabola ngokuhamba kwesikhathi ngenxa yokuchayeka elangeni ngokwalo, ukushisa kwendawo, umswakamo, nokujuluka, kwehle kancane kancane amandla azo amakhemikhali nokufana ngokomzimba esikhunjeni, okunciphisa ukuvikelwa kwe-SPF okushiwo kakhulu phakathi namahora ambalwa. Odokotela besikhumba nezinhlangano zezempilo bayatusa ngokufanayo ukuthi kugcotshwe kabusha njalo ngemva kwama-2 hours, noma kaningi uma ubhukuda, ujuluka kakhulu, uzisula ngetawula, noma wenza imidlalo yamanzi, ngoba lezi zinto zingasusa noma zinciphise umkhiqizo ebusweni besikhumba futhi zidale izikhala ekuvikelweni. Ngisho nokuvikela ilanga okumelana namanzi, okuhlolwa ukuthi kusebenza ngemva kokucwiliswa emanzini imizuzu engu-40 noma engu-80, kuyalahlekelwa amandla okuvikela ngokuhamba kwesikhathi futhi kudinga ukugcotshwa kabusha ukuze kugcinwe izinga lokuvikela elibhalwe kumkhiqizo kumalanga e-UVA ne-UVB. Emabhizinisini akhiqiza noma asebenzisa izinto ezivikela i-UV, njengamalebula enziwe ngokwezifiso nokupakishwa okuvela ezinkampanini ezinjengeGurongprint (Shanghai) Co., Ltd., ukuqonda ukuqina nokuphila isikhathi eside kokwelashwa okuvimba i-UV ngokuhlolwa kokuguga okusheshisiwe kubalulekile ekugcineni ukusebenza komkhiqizo nokwaneliseka kwamakhasimende ngokuhamba kwesikhathi. Ukwamukela uhlelo oluhlelekile lokugcotsha kabusha yisinyathelo esilula kodwa esibalulekile ekuqinisekiseni ukuvikelwa okuqhubekayo usuku lonke, futhi ukubeka izikhumbuzo noma ukusebenzisa izinhlelo zokusebenza zomakhalekhukhwini kungasiza ukwenza lo mkhuba ube ngokwemvelo kubantu ngabanye nasemindenini ngokufanayo.

Abantu abaningi abakubuki ngokwanele inani likasondo elidingekayo ukuze kutholakale izinga lokuvikelwa elibekiwe, ngokuvamile bagcoba ungqimba oluncane olwehlisa ukusebenza komkhiqizo lube yingxenye encane ye-SPF eshiwo, futhi kushiya isikhumba sengozini enkulu. Isincomo esijwayelekile esivela emihlahlandlela yezokwelapha zesikhumba ukusebenzisa cishe amamiligremu amabili kasondo ngesentimitha-skwele ngalinye lesikhumba, okuhumusha ukuthi kugcwalise ingilazi yoshukela, cishe amamililitha angu-30, ukuze kumbozwe umzimba wonke womuntu omdala ngokwanele kusukela ekhanda kuye ezinyaweni. Uma usondo lugcotshwa kancane kakhulu, ukuvikelwa kwe-SPF kwehla ngendlela engalingani; isibonelo, ukugcoba ingxenye yamanani anconyiwe kasondo we-SPF 30 kungahlinzeka ukuvikelwa kwe-SPF 5 kuya ku-10 kuphela, okuphansi kakhulu kunalokho abantu abaningi abacabanga ukuthi bakuthola emkhiqizweni. Izindawo ezivamile ezingavikelekile ngokwanele ngenxa yokugcotshwa kancane noma ukweqiwa zifaka izindlebe, ingemuva lentamo, izihloko zezinyawo, isikhumba sekhanda eduze komugqa wezinwele, kanye nezandla ezingemuva, zonke ezisengozini enkulu yokushiswa yilanga kanye nomonakalo wesikhumba oqongelelwayo ngokuhamba kwesikhathi. Ukuze kuqinisekiswe ukumbozwa okwanele, kusiza ukugcoba usondo ngezigaba ezimbili, uvumele owokuqala umunce imizuzu embalwa ngaphambi kokwengeza owesibili, futhi usebenzise izinkomba ezibonakalayo ezifana nongqimba olubonakalayo esikhunjeni ukuze uqinisekise ukuthi usebenzise umkhiqizo owanele. Ubuningi bokugcotshwa obufanele bubaluleke ngokufanayo nezinga le-SPF ngokwalo, futhi abasebenzisi kufanele babeke phambili ukumbozwa okuphelele nokunomusa ukuze ngempela bazuze emikhiqizweni yabo yokuvikela ilanga futhi bagweme umuzwa wokuphepha ongamanga ongaholela ekushisweni okungalindelekile.

Nakuba ukuvikela isikhumba ekuchayekeni elangeni ngokweqile kubalulekile ukuvimbela ukulimala, ukuguga ngaphambi kwesikhathi, nomdlavuza wesikhumba, ukugwema ilanga ngokuphelele kungaba nemiphumela emibi empilweni yonke, ikakhulukazi maqondana nokwenziwa komzimba kweVithamini D ngokwemvelo. Umzimba womuntu udinga ukuchayeka emisebeni ye-UVB ukuze uguqule i-cholesterol esikhunjeni ibe iVithamini D, edlala indima ebalulekile ekumuncweni kwe-calcium, ekugcineni ukuqina kwamathambo, ekulawuleni amasosha omzimba, nasekuzinzeni kwemizwa, futhi ukungachayeki elangeni ngokwanele kungaholela ekuntuleni kwevithamini nezinkinga zezempilo ezihlobene nayo njengokuqina kwamathambo, ukuba buthaka kwamasosha omzimba, nokuphazamiseka kwemizwa okuhambisana nesizini. Ukuchayeka elangeni ngokulinganisela, ngokuhlakanipha, cishe imizuzu engu-10 kuya kwengu-30 ngosuku esikhunjeni esingavikelwe, kuye ngohlobo lwesikhumba, indawo, isikhathi sonyaka, nesikhathi sosuku, kungasiza ekugcineni amazinga anele eVithamini D ngaphandle kokukhulisa kakhulu ingozi yomdlavuza wesikhumba noma ukuguga kwesikhumba ngenxa yelanga kubantu abaningi. Ukhiye usekutholeni ibhalansi phakathi kokuvikela ilanga nokuchayeka elangeni: vikela isikhumba sakho ngezikhathi eziphezulu ze-UV ngokuvamile phakathi kwe-10 ekuseni ne-4 ntambama lapho imisebe inamandla kakhulu, futhi cabanga ngezikhathi ezimfushane zokuchayeka ekuseni noma ntambama ngezikhathi ezingezona eziphezulu ngokumboza izingalo nemilenze kancane. Kubantu abahlala ezindaweni ezisenyakatho, abanesikhumba esimnyama, abagqoka izingubo ezimboza umzimba wonke ngenxa yamasiko noma izizathu zenkolo, noma abakhathazekile ngokuntula iVithamini D, imithombo yokudla efana nezinhlanzi ezinamafutha nokudla okunomsoco, kanye nezithasiselo, kunikeza ezinye izindlela eziqinisekile zokugcina amazinga anempilo ngaphandle kokuthembela ekuchayekeni elangeni ngaphandle kokuvikelwa. Indlela enobuhlakani ehlanganisa ukuvikela ilanga nokuchayeka elangeni ngokuhlosiwe, ngokuhlakanipha, ivumela abantu ukuthi bajabulele izinzuzo zokukhanya kwelanga ekwenzeni iVithamini D nasekuthuthukiseni impilo yengqondo kuyilapho behlisa ubungozi bezempilo obuhambisana nokuchayeka ngokweqile.

Ukuqalisa isu eliphelele lokuvikelwa elangeni kubalulekile ekugcineni impilo yesikhumba nokuvimbela umonakalo wesikhathi eside obangelwa yimisebe ye-UV, futhi izinqubo ezisekelwe ebufakazini ezichazwe kulesi sihloko zinikeza isisekelo esiqinile sokufeza lowo mgomo ezimweni zomuntu siqu nezomsebenzi. Ngokuqonda umehluko oyisisekelo phakathi kwemisebe ye-UVA neye-UVB, ukusebenzisa zombili izindlela zokuvikela eziqinile njengezingubo nezambulela kanye nokuvikelwa okuthambile ngokusebenzisa imikhiqizo yokuvikela ilanga ekhethwe kahle, nokukhetha amathuluzi nemikhiqizo ehambisana nezidingo zomuntu ngamunye nezinhlobo zesikhumba, abafundi banganciphisa kakhulu ubungozi bokushiswa yilanga, ukuguga kwesikhumba ngaphambi kwesikhathi, nomdlavuza wesikhumba ekuphileni kwabo. Ukuqeda izinganekwane ezivamile zokuvikelwa elangeni kusiza ekuqedeni imicabango eyingozi engase yehlise imizamo yokuvikela, iqinisekise ukuthi abantu benza izinqumo ezinolwazi ezisekelwe ebufakazini besayensi hhayi ezinganekwaneni ezidlangile noma ezimangalweni zokumaketha. Ezinkampanini, ikakhulukazi ezimbonini yokuphrinta, yamalebula, nokupakisha njenge-Gurongprint (Shanghai) Co., Ltd., ukufaka ubuchwepheshe nezinto ezimelana ne-UV ezixazululweni ezenziwe ngokwezifiso kubonisa ukuzibophezela kwekhwalithi, ukuqina, nokwaneliseka kwamakhasimende kuyilapho kubhekwana nezinselele zomhlaba wangempela ezibhekana nemikhiqizo echayeke elangeni. Siyakhuthaza abafundi ukuthi bamukele le mikhuba yokuvikela ilanga njengengxenye yemikhuba yabo yansuku zonke, babelane ngalolu lwazi nomndeni, abangane, nozakwabo, futhi bahlole eminye imithombo yolwazi oluthembekile mayelana nokuphepha kwe-UV nempilo yesikhumba. Ukuze ufunde kabanzi mayelana nezinketho zamalebula nokupakisha okumelana ne-UV okwenziwe ngokwezifiso, vakashela kwethuIzinsizakalo ikhasi, futhi hlala unolwazi ngemikhuba yezimboni nokusungula izinto ezintsha ngokubheka kwethu Izindaba ikhasi. Noma yimiphi imibuzo noma ukuxoxa ngezidingo zakho ezithile zokuvikela ilanga zokupakisha nokulebula, sicela uzwe ukhululekile ukusithinta nge-Ikhasi Elisha. Ngokubeka ukuvikela ilanga phambili kuzo zonke izici zempilo, sonke singakwazi ukujabulela izindawo zangaphandle ngokuphephile nangokuzibophezela ngenkathi sivikela impilo yethu nemikhiqizo yethu iminyaka ezayo, futhi siyakumema ukuba uhlole Ikhaya ikhasi ukuze uthole ukubuka okuphelele kokunikezwa kwethu namanani ethu.
