Sisenenyanga egcwele phambi kwethu, egcwele ulwandle, isihlabathi, amanzi olwandle nemigoqo yasolwandle; okungukuthi, inyanga yasehlobo. Labo abaqale iholide labo ezinsukwini ezimbalwa ezedlule kufanele cabangela isikhumba sakhoAkufanele bangayinaki futhi kufanele bayinake kakhulu ngalesi sikhathi sonyaka.
Umkhiqizo oyisisekelo lokho akufanele kungabikho ezikhathini zethu zeholide ukhilimu welanga. Okungathi iholide lakho libhekiswe olwandle noma endaweni esezintabeni. Abantu abaningi benza iphutha ngokungazivikeli emisebeni yelanga entabeni futhi imisebe nayo ishaya isikhumba sethu ngqo.
Ukukhetha i-sunscreen njalo ehlobo kuba yinto ejabulisa kakhulu, eminyakeni edlule abacwaningi bakhipha imikhiqizo emisha namafomula amasha, kepha, Yikuphi okuhle kakhulu ngakunye? Ngokulandelayo sizohlaziya ukuthi yimaphi ama-agent akhiqizwa okhilimu ukuze ngokuzayo lapho singabanjwa saziswe kabi.
Uma sikhuluma ngakho ilanga, ngokuvamile kunezinhlobo ezimbili, lezo ezisebenzayo kukhombisa ukukhanya okukuvimbela ukuthi kungangeni emzimbeni, noma lawo amunca imisebe ngaphambi kokuba zingene esikhunjeni. Abantu bakhathazeka nge-SPF kuphela, okungukuthi, ukugxila kokhilimu ukusivikela ekushisweni okuzayo okubangelwa yi-UVB, kepha namuhla siyazi ukuthi kufanele sinake lokho futhi usivikele emisebeni ye-UVA ne-IR.
Izingxenye zesikrini selanga
Imisebe ye-UVA banesibopho sokulimala kwesikhumba. Ingabe yibo ukwandisa ingozi yomdlavuza wesikhumba yize kungabangeli ukushiswa yilanga. Banekhono lokungena esikhunjeni ngokujula, okudala imibimbi nokuguga kwesikhumba. Konke lokhu ngokuhamba kwesikhathi kunqwabelana kwimemori yesikhumba sethu futhi ngokuhamba kwesikhathi sibona ukonakala kokuchayeka kwelanga okwedlule.
Omunye umenzeli okufanele acatshangelwe esikrinini selanga yi IR, yimisebe ye-infrared, lezi azibonakali kodwa zinesibopho sazo sisebenzise, sinikeze amandla kagesi kagesi nokushisa. Ukukhanya okuqhamuka elangeni kunemisebe yohlobo A, B no-C, kepha yi-A kuphela engena esikhunjeni iye ngaphezulu kwesikhumba. Ngokwandisa ukushisa komzimba wethu lokhu kudala ukuthi isikhumba sizwele kakhulu emisebeni ye-ultraviolet.
Izihlungi kusikrini selanga
- SPF: Yisifinyezo se- "Isici Sokuvikelwa yilanga".
Ngamafuphi, kungukusebenza kwe-sunscreens ukuvikela isikhumba ekushisweni yilanga okubangelwa yi-UVB. I-SPF yaziwa nge isikhathi esisithathayo ukuze isikhumba sibomvu futhi umkhiqizo uqala ukulahlekelwa ukusebenza. Ukuphakama kwe-SPF, isikhathi eside sokuchayeka elangeni.
Isibonelo, isihlungi selanga se-15 akuyona ingxenye yalokho kwe-30 I-15 ivikela isikhumba sethu 93% UVB, futhi Ama-30 avikela ama-97%, lawo angama-50 avikela ama-98%. Ukwazi ukuvikeleka kokhilimu kulula njengokubona ukuthi kuthatha isikhathi esingakanani ukuthi umuntu abomvu, uma kuthatha imizuzu eyi-10 ngesikrini selanga se-SPF 15 kungaphindaphindeka futhi kungaba yimizuzu eyi-150 ngaphambi kokusha.
- Ububanzi obubanzi
Lo menzeli uyanakekela linganisa ubude obuhlukahlukene bemisebe yelanga. Ikhombisa ukuthi umkhiqizo usebenza nini ekushisweni yilanga nokonakala kwesikhumba, imibimbi nokuguga.
- Ukumelana namanzi
Izihlungi zelanga imvamisa ayinamanzi, ngaphandle uma kushiwo ngokusobala kumalebula womkhiqizo. Isikrini esivikela ilanga asinamanzi lapho singacwiliswa emanzini imizuzu engama-40 kuya kwengama-80.
Ukulimala kwesikhumba
Imisebe ye-Ultraviolet ingadala izinhlobo ezimbili zomonakalo, ezingalungiseki futhi zisheshe:

Eminyakeni yamuva nje kuye kwabonakala ukuthi imisebe yelanga inamandla kangakanani futhi iyingozi kangakanani esikhunjeni sethu. Ilanga liphilile kakhulu futhi kufanele sibe nomthamo wethu wansuku zonke kepha kulezi zinyanga zasehlobo kufanele sinake kakhulu ukuze singabeki impilo yethu engcupheni.
Nayi i-video eye yasabalala kuleli sonto. Ividiyo ekhombisa ngempela ukuthi imisebe ye-ultraviolet isithinta kanjani isikhumba sethu.
