Ingabe i-sunscreen iyaphela?

Imfundo Yezempilo

Ilanga liphumile. Isikhathi sifudumele. Futhi usuzoshaya olwandle… noma ipaki… noma imizila yokuhamba izintaba yosuku lokuzijabulisa. Ngaphambi kokuba uhambe, uthatha ibhodlela le- isivikelo selanga ukufaka esikhwameni sakho — kepha masinyane uqaphele ukuthi usuku lokuphelelwa yisikhathi seludlulile. Noma ukuthi alukho usuku lokuphelelwa yisikhathi olubhalwe nhlobo. Ingabe i-sunscreen iphephile ukusebenzisa? Ngabe isazokuvikela ku- ukushiswa yilanga okubi ? Noma ungcono ukuyiphonsa bese uthenga ibhodlela elisha?

Ingabe i-sunscreen iyaphela?

Isikrini selanga siyaphelelwa yisikhathi, futhi kungenzeka singasebenzi ngempumelelo ngalolo suku, ngokusho UJoshua Draftsman, MD , umqondisi wocwaningo lwezimonyo nolomtholampilo wesikhumba e-Mount Sinai Hospital eNew York City.

Izinga lokuvikelwa elibhalwe ebhodleleni lingaqinisekiswa kuphela kuze kufike usuku lokuphelelwa yisikhathi, kusho yena. Ngemuva kwalelo phuzu, i-sunscreen cishe izonikeza izinga elithile lokuvikelwa; kodwa-ke, hhayi kakhulu njengoba inikeze ekuqaleni.

Njengomkhiqizo othengiswayo, i-sunscreen ilawulwa yi-Food and Drug Administration (FDA) futhi kudingeka ukuthi kube nesikhathi sokuphelelwa yisikhathi esibhalwe kwilebula laso — noma sifakazele ukuthi isikhathi salo seshalofu sesidlulile eminyakeni emithathu ngaphambi kosuku lokwenza. Lokho kusho ukuthi, nganoma yisiphi isizathu, ibhodlela lakho lesikrini selanga alinalo usuku lokuphelelwa yisikhathi eligxiviziwe, kufanele libe kuhle kuze kube yiminyaka emithathu ngemuva kosuku lokuthenga kwalo. Ngaphandle kwalokho, kungenzeka ukuthi ngeke ivimbele leyo misebe ye-ultraviolet (UV).

Noma i-sunscreen yakho ingakapheli isikhathi, uzofuna ukuqinisekisa ukuthi akukho zinguquko ezisobala ekwakhiweni kusukela okokugcina lapho uyisebenzise.

Uma ingabukeki, ingezwa, noma inuka ngendlela ebibukeka ngayo ngenkathi uyiqala ukuyithenga, kufanele uyiphonse, kusho uDkt Zeichner. Angithandi noma ngubani azibeke engcupheni uma kukhulunywa ngokuvikelwa kwelanga.

Ingabe kulungile ukusebenzisa i-sunscreen ephelelwe yisikhathi?

Ingozi enkulu yokusebenzisa i-sunscreen ephelelwe yisikhathi ukuthi izithako zizolahlekelwa ukusebenza kwazo futhi unethuba eliphakeme lokushisa. Kodwa kungaba neminye imiphumela esikhunjeni sakho, kusho uMarisa Garshick, MD, ongudokotela wesikhumba oqinisekiswe ebhodini eNew York Isikhungo Sokuhlinzwa Kwezesikhumba kanye Nezimonyo .

Ama-sunscreen aphelelwe yisikhathi angazizwa noma abukeke ehlukile efomini yawo yasekuqaleni ngamakhemikhali elanga anezakhi zamakhemikhali ne-sunscreens ebonakalayo eyehlisa isithunzi, usho kanje. Uma ukungaguquguquki kwehlukile, kungahle kungazizwa ngendlela efanayo esikhumbeni futhi kwenze isikhumba sibe nokuzwela noma ukucasuka. Ngokunjalo, uma kukhona okonga okonakele lapho umkhiqizo uphela, kungakhuphula amathuba amabhaktheriya asebhodleleni, okungathi ngokombono futhi kuholele ekuthelelekeni.

Lokho kusho, uma usempintsheni futhi ukungaguquguquki kusabukeka kulungile, ukusebenzisa i-sunscreen ephelelwe yisikhathi kungenzeka kungabi inketho embi kakhulu.

Ngitshela iziguli zami ukuthi i-sunscreen ephelelwe yisikhathi ingcono impela kunokungabi nelanga nhlobo, kusho uDkt Zeichner. Kodwa-ke, ngithanda iziguli zami ukuthi zithenge i-sunscreen entsha njalo ngesizini. Uma usebenzisa i-sunscreen kahle, ibhodlela olithengayo ngoSuku lweSikhumbuzo nakanjani akufanele lihlale kuze kufike uSuku Lomsebenzi.

Uma isikrini sakho selanga siphelelwe yisikhathi, kufanele usilahle kude. Ngokungafani nemithi kadokotela , ayikho inqubo ephakanyisiwe yangempela yokulahla izikrini zelanga. Uhlelo lokuqoqa imithi lendawo lungayithatha, kepha abaningi abayamukeli imikhiqizo yokunakekelwa komuntu (okucatshangelwa i-sunscreen). Uma ufuna ukusebenzisa kabusha ibhodlela, gcoba isivikelo selanga esingasetshenzisiwe kudoti kunokuba wehlise udreyini ukuvimbela amakhemikhali angadingeki ukuthi angene emanzini.

Ukuphepha kwelanga

Umdlavuza wesikhumba uhlobo oluvame kakhulu lomdlavuza e-U.S., Futhi ukulimala kwelanga emisebeni ye-UV kungenzeka ngemizuzu eyi-15 kuphela, ngokusho kwe Izikhungo Zokulawulwa Nokuvikelwa Kwezifo . Yingakho kubaluleke kakhulu ukuqhuba ukuphepha kwelanga unyaka wonke, kufaka phakathi:

• Ukulinganisela ukuthi uchitha isikhathi esingakanani elangeni , ikakhulukazi phakathi kwamahora ka-10 ekuseni no-4 ntambama, lapho imisebe iba namandla kakhulu.
• Ukumboza ngangokunokwenzeka nesigqoko esinomphetho obanzi, izibuko zelanga, namahembe noma ibhulukwe elinemikhono emide. Imibala emnyama noma ekhanyayo ihamba phambili, ngokusho kwe- Isisekelo Somdlavuza Wesikhumba , njengoba bemunca imisebe kunokuba bayivumele ingene. Imikhiqizo eminingi yezingubo manje ifaka imininingwane ye-Ultraviolet Protection Factor (UPF) —ingakanani imisebe ye-UV indwangu evimba — ekubhaleni kwabo.
• Ukuhlala emthunzini. Izambulela, amatende, nezihlahla kunganikeza indawo yokuhlala enhle elangeni elishisayo.
• Futhi-ke, egqoke okokuvikela ilanga noma kungenzekani — usengasha ngisho emthunzini.

Ngisikhetha kanjani isivikelo selanga esifanele?

Isikrini selanga ngokuvamile sivikela isikhumba ezinhlotsheni ezimbili zemisebe: i-UVA ne-UVB. Imisebe ye-UVA ihlotshaniswa nokuguga kwesikhumba, kuyilapho imisebe ye-UVB ihlotshaniswa nokushisa kwesikhumba — yomibili ifaka engcupheni yokuba nomdlavuza wesikhumba.

UVA ne-UVB

Kunezinkomba ezimbili okufanele uzibheke lapho uthenga i-sunscreen: Uma ilebula lithi i-wide spectrum khona-ke uyazi ukuthi inokuvikelwa kwe-UVA ne-UVB. I-SPF (sun protection factor) ilinganisa izinga lokuvikelwa kwe-UVB.

SPF

Isincomo samanje esivela e-American Academy of Dermatology and Skin Cancer Foundation ukuthi kukhethwe i-sunscreen okungenani nge-SPF 30, kusho uDkt Zeichner. Mina ngokwami ​​ngincoma ukuthi iziguli zami zigcobe i-sunscreen nge-SPF ephezulu kakhulu. Emhlabeni wangempela, asisebenzisi i-sunscreen eningi njengoba kufanele futhi kasiphindi sisebenzise njalo emahoreni amabili. Ngenxa yalokho, izinga lokuvikelwa esikutholayo lihlanjululwa.

Kunemikhiqizo yokunakekelwa kwesikhumba ngaphandle kwesikrini selanga esine-SPF, kufaka phakathi izinto zokuthambisa, i-lip balm, nezimonyo. Kodwa-ke, le mikhiqizo ayihlali inokuvikelwa kwe-UVA, yingakho kusabalulekile ukugqoka i-sunscreen.

Amaminerali noma amakhemikhali

Uzophinde uthande ukucabangela uhlobo lwe-sunscreen oyithengayo. Kunezimbili: amaminerali (owaziwa nangokuthi ngokomzimba) namakhemikhali.

Isikrini selanga samaminerali iqukethe i-zinc oxide noma i-titanium dioxide futhi isebenza njengesithiyo ngokomzimba ukukhombisa ilanga (cabanga: abaqaphi abasindayo abanomugqa omhlophe emakhaleni abo).

Isikrini selanga samakhemikhali , ngakolunye uhlangothi, imunca imisebe yelanga njengesiponji futhi iqukethe eyodwa (noma eminingi) yamakhemikhali alandelayo: njenge-avobenzone, i-homosalate, i-octisalate, i-oxybenzone, ne-octinoxate. Bobabili banobuhle nobubi babo, ngakho-ke uma ufuna isivikelo selanga esihle kuwe, khuluma nodokotela wesikhumba sakho.

Kungakhathalekile ukuthi ukhetha ini, sebenzisa cishe inani elilingana nengilazi lokudubula (cishe izipuni ezimbili) ezindaweni eziveziwe zomzimba nobuso, imizuzu eyi-15 ngaphambi kokuthi uphume ukuyinika isikhathi sokumunca. Ngaphezu kokufaka isicelo njalo emahoreni amabili, uzofuna ukugqoka elinye ijazi ngemuva kokubhukuda noma ukuphuka izithukuthuku ezisindayo, ngoba iningi lesikrini selanga liyobe seligezile noma laconsa. Kodwa yoma kuqala — uDkt. UZeichner uthi i-sunscreen ngeke imunce ngokugcwele uma isetshenziswa esikhunjeni esimanzi.

Uma kukhulunywa ngokugcina isikrini sakho selanga, qiniseka ukuthi sisegumbini lokushisa, ugweme ukushisa okweqile. Ungayishiyi ihleli elangeni noma emotweni eshisayo, ngoba lokho kungaphazamisa amandla ayo. Ngemuva kwalokho, ngakho konke lokho engqondweni, jabulela usuku lwakho elangeni (noma okungcono, umthunzi)!
