Ukutshiswa kwelanga: Ngaba ndingayisebenzisa ngeglasi

Kwintliziyo yokushisa ilanga kuyimpembelelo yemitha ye-ultraviolet elukhumbeni. Kukho iintlobo ezintathu zolu hlobo. Abo babamba igama elithi "C", phantse bafikelele emhlabeni, ngoko kuya kuthintela kakhulu isikhumba sethu. Kodwa imibala "B" ikuvumela ukuba ufumane i-hue yegolide efunwayo ngokukhawuleza, kodwa kule ndlela eyingozi. I-tan ekhuselekileyo yinto efunyenwe ngokutyhila isikhumba kwimisindo "A". Inyaniso yesiphumo esinamandla kule meko idinga ixesha elide. Kodwa isiphumo siyafaneleka: le tan iphephile kwaye ihlala ixesha elide.

Kutheni ilukhuni luba mnyama?

Kuba utshintsho emthunzini wesikhumba, kunye nobukhulu besikhumba, emzimbeni womntu udibana neeseli ezikhethekileyo. Ziqukethe i-pigment melanin, ngoko ke igama elithi-melanocytes. Ukunyanzelisa isikhumba ukuba sibe mnyama, bayakhusela umzimba kwimiphumo emibi yemitha yelanga. Kwaye ukugqithisa kakhulu imisebe ye-ultraviolet, ngakumbi i-pigment ivelisa iiseli. Into ebangelisayo yale seli iwukuthi ayinakucima nje kuphela, kodwa iphinda ikhanyise (ukucaphukisa itan) kwilizwe langaphambili. Umlinganiselo we-melanin elukhumbeni unqunywe ngokwemizimba, phantsi kweemeko eziqhelekileyo kugcinwa kwelinye nqanaba.

Ubungakanani bokushisa ilanga

Kuyaziwa ukuba ukutywala ixesha elide leziyobisi ezithile kunokunciphisa imisebenzi ekhuselekileyo yomzimba, kubandakanywa nokwazi kwesikhumba ukuvelisa i-melanin. Ngoko ke, abanye abantu bavunyelwe ukutshisa ilanga. Oku kufana nokusebenza kwintsholongwane apho ulusu luqulethe i-pigment encinci ukujongana ngokufanelekileyo ngendalo. Kungakhathaliseki ukuba bangaphi abantu abanjalo belele elunxwemeni, "abayithathi" i-tan, iingozi ezinobungozi be- ultraviolet zidlula ngokukhawuleza phantsi kwesikhumba kwaye zilimaze umzimba.

Into ebalulekileyo ye-tan esemgangathweni kukuphakama kwelanga ngaphaya kwesigxina. Ububanzi bomhlaba budlala indima ebalulekileyo kule ngxaki. Yingakho abantu abahlala kwimimandla eshushu yomhlaba banomthunzi omnyama wesikhumba. Kodwa ubude belanga abuchaphazeli kuphela indawo yokuhlala. Ixesha lemini kunye nexesha lonyaka kubalulekile apha. Ngokukodwa, ukuba kukho imozulu ephakathi, apho utshintsho lwamaxesha lukhankanywe ngokukodwa.

Enye into ebalulekileyo ihambelana nomoya ngokwawo. I-purer kunye nebalaseleyo, imitha enkulu ifikelela emhlabeni kwaye ibonakala kuyo. Ichaphazela ukushisa kwelanga nokuphakama kwelanga: ngolunye usuku ezintabeni kuya kunika umphumo omkhulu kuneveki yokuhlala kwiindawo eziselwandle. Phakathi kweengqameko ezikhethiweyo zekhephu, impembelelo yeemitha zelanga ziphakame kangangokuthi abagibeli bafanele basebenzise iindlela ezikhuselekileyo zokukhusela, iziglasi ezikhethekileyo kunye neekram. Kodwa nazo zixhobo azizinzi kwi-tan ekhanyayo. Kwaye konke oku kubandakanywa kubanda kakhulu phakathi kweenkwenkwezi.

Ngaba ndiyakwenza ngeglasi

Musa ukuthatha ubomvu obushushu bokuqala kokutshisa ilanga. Inokwenzeka ukuba, iya kudlula embalwa imizuzu. Emva kwakho konke, ukufaka isiqhumiso kwisihlunu kwithuba elithile, siza kubona i-speck ebomvu. Kodwa akukho mntu uya kugxeka ngexesha elifanayo ukuba ibhotile yamanzi eshushu iyabangela ukushona kwelanga. Enye into yokuba ubeka endaweni yeefestile eziqhelekileyo nge-plexiglas. Emva koko unokutshisa ilanga unyaka wonke.

Ngaba ndifuna ukuzikhusela?

Ukuxhalaba malunga nokuba kunokwenzeka ukuba usebenzise igalazi, kuyimfuneko kuphela kulabo bantu abaxhomekeke kwimbonakalo yeebala. Kule meko, banokukhupha nantoni na. Kunconywa ukusebenzisa izixhobo ezikhuselekileyo zokukhusela. Ukulungelelaniswa kwimihla yokuqhelekileyo, njengoko idla ngokuba ne-UV-filter. Ukukhuselwa kwe-ultraviolet kusetyenziswa ngokubanzi kubuso nasentanyeni apho iindawo ezinemibala eboyiweyo zihlala khona.

Kwakhona, umzimba womntu uye wavelisa ukukhusela kwendalo ngaphezu kwe-melanin. Ngethuba elide elangeni, ulusu luyakhupha, olukhusela ekungeneni kwe-ultraviolet.
