Phakathi kwemiqulu engapheli yeTikTok ngaphambi kokuthi uvuke ekuseni, usuku lokusebenza lwehora lesishiyagalombili kukhompyutha, neziqephu ezimbalwa kwiNetflix ebusuku, kuphephile ukusho ukuthi uchitha usuku lwakho lonke phambi kwesikrini. Eqinisweni, umbiko wakamuva weNielsen wathola abaseMelika bachitha cishe isigamu sosuku lwabo — amahora ayi-11 ukuba abe nse — entweni ethile. Ukukhuluma iqiniso, le nombolo ifaka nokusakaza umculo nokulalela ama-podcast, kepha yingxenye ethusayo (yize ingamangazi ngokuphelele) impilo yakho yansuku zonke.

Ngaphambi kokuthi ucabange ukuthi lokhu kuzophenduka inkulumo ethi "beka phansi ifoni yakho", yazi ukuthi isikhathi sesikrini asisibi sonke; iyisixhumanisi somphakathi futhi izimboni zincike kubuchwepheshe ukwenza ibhizinisi—heck, le ndaba ibingeke ibe khona ngaphandle kwezikrini.

Kepha iqiniso ukuthi sonke leso sikhathi sesikrini sinomthelela omubi empilweni yakho ngokusobala (ukulala kwakho, inkumbulo, kanye ne-metabolism) nezindlela ezingaziwa (isikhumba sakho).

Ngokusobala ochwepheshe (nomama wakho) bazokutshela ukuthi unciphise isikhathi sakho sesikrini, kepha kuya ngomsebenzi wakho noma indlela yokuphila okungenzeka ukuthi kungenzeka. "Ngicabanga ukuthi kufanele samukele ubuchwepheshe kanye nazo zonke izindlela ezimangalisayo ezithuthukise izimpilo zethu. Vele uqiniseke ukuthi uvikela isikhumba sakho ngenkathi wenza," kusho uJeniece Trizzino, iphini likamongameli wezokuthuthukiswa komkhiqizo e-Goodhabit, uhlobo olusha lokunakekelwa kwesikhumba olwenziwe. ngokukhethekile ukulwa nemiphumela yokukhanya okuluhlaza okwesibhakabhaka.

Qhubeka ufunda ukuze uqonde kangcono umthelela lokhu kukhanya okuluhlaza okuvela kumadivayisi akho okungaba nawo esikhumbeni sakho nokuthi yini ongayenza ukuze ukuvimbele. (Okuhlobene: Izindlela ezi-3 Ifoni Yakho Eyonakalisa Isikhumba Sakho nokuthi Yini Ongayenza Ngayo.)

Kuyini ukukhanya okuluhlaza okwesibhakabhaka?

Iso lomuntu liyakwazi ukubona ukukhanya njengemibala ethile lapho lifinyelela ubude obuthile. Ukukhanya okuluhlaza okwesibhakabhaka uhlobo lokukhanya olukhipha ukukhanya okunamandla aphezulu abonakalayo (HEV) okuhlala engxenyeni eluhlaza okwesibhakabhaka yobubanzi bokukhanya obubonakalayo. Ngomongo, ukukhanya kwe-ultraviolet (i-UVA / UVB) kusibuko sokukhanya esingabonakali futhi kungangena ezingxenyeni zokuqala nezesibili zesikhumba. Ukukhanya okuluhlaza okwesibhakabhaka kungafinyelela yonke indlela kusendlalelo sesithathu, kusho uTrizzino.

Kunemithombo emibili eyinhloko yokukhanya okuluhlaza okwesibhakabhaka: ilanga nezikrini. Ilanga empeleni liqukethe ukukhanya okuluhlaza okwesibhakabhaka okuningi kune-UVA ne-UVB kuhlangene, kusho uLoretta Ciraldo, MD, udokotela wesikhumba eMiami. (PS Uma kwenzeka uzibuza: Yebo, ukukhanya okwesibhakabhaka yisizathu esenza ubone isibhakabhaka njengombala oluhlaza okwesibhakabhaka.)

Zonke izikrini zedijithali zikhipha ukukhanya okuluhlaza okwesibhakabhaka (i-smartphone yakho, i-TV, ikhompyutha, ithebulethi, ne-smartwatch) futhi umonakalo usekelwe ekusondeleni kwensiza (ukuthi ubuso bakho busondele kangakanani esikrinini) nobungako bedivayisi, kusho uTrizzino. Kunempikiswano ezungeza ukuthi ukukhanya okukhanya ngamandla nobude buqala nini ukudala umonakalo, futhi akucaci ukuthi ukukhanya kwakho okuluhlaza okwesibhakabhaka okuningi kuvela elangeni ngoba kungumthombo onamandla, noma izikrini ngenxa yokusondela kwabo nesikhathi sokusetshenziswa.

Ukukhanya okwesibhakabhaka kungasithinta kanjani isikhumba?

Ubudlelwano phakathi kokukhanya okwesibhakabhaka nesikhumba buyinkimbinkimbi. Ukukhanya okuluhlaza okwesibhakabhaka kufundelwe ukusetshenziselwa imikhuba yesikhumba ukwelapha izimo zesikhumba, njengezinduna noma i-rosacea. (USophia Bush ufunga ukwelashwa okuluhlaza okwesibhakabhaka nge-rosacea yakhe.) Kodwa ucwaningo olusha luphumile olukhombisa ukuthi ukukhanya okuphezulu, okuhlala isikhathi eside ekukhanyeni okuluhlaza okwesibhakabhaka kungahlotshaniswa nezimo ezithile zesikhumba ezingaphansi kokuhle, okufana nokuchayeka ku-UV ukukhanya. Kucatshangwa ukuthi ukukhanya okuluhlaza okwesibhakabhaka, njenge-UV, kungadala ama-radicals wamahhala, okukholelwa ukuthi yimbangela yawo wonke lowo monakalo. Ama-radicals amahhala ayizinhlayiya ezincane zezimonyo ezenza umonakalo esikhunjeni, njengokuguqulwa kombala nemibimbi, kusho uMona Gohara, MD, udokotela wesikhumba futhi ohambisana noprofesa wezokwelapha eYale School of Medicine.

Ucwaningo olulodwa luye lwabonisa nokuthi ukukhiqizwa kwe-melanin esikhunjeni kuphindwe kabili futhi kwaqhubeka isikhathi eside lapho kuvezwa ukukhanya okuluhlaza okwesibhakabhaka kuqhathaniswa ne-UVA. Ukukhuphuka kwamazinga e-melanin kungaholela ezinkingeni ze-pigmentation ezifana ne-melasma, izindawo zeminyaka, nezindawo ezimnyama ngemuva kokuphuma. Futhi lapho abahloli bevezwa ukukhanya okuluhlaza okwesibhakabhaka bese behlukaniswa nge-UVA, kwaba nokubomvu nokuvuvukala kwesikhumba okuvezwe ukukhanya okuluhlaza okwesibhakabhaka kunomthombo wokukhanya we-UVA, kusho uDkt Ciraldo.

Kalula nje: Uma uvezwa ukukhanya okuluhlaza okwesibhakabhaka, isikhumba sakho siyacindezeleka, esidala ukuvuvukala futhi siholele ekulimaleni kwamaselula. Ukulimala kwamangqamuzana esikhumba kubangela izimpawu zokuguga, ezifana nemibimbi, izindawo ezimnyama, nokulahleka kwe-collagen. Ngezindaba ezithile ezinhle: Ayikho idatha ephakamisa ukuhlobana phakathi kokukhanya okuluhlaza okwesibhakabhaka nomdlavuza wesikhumba.

Udidekile ukuthi ukukhanya okuluhlaza okwesibhakabhaka kubi noma kuhle? Kubalulekile ukuthi wazi ukuthi zombili lezi zinto ezithathwayo zingaba yiqiniso: Ukuvezwa kwesikhashana esifushane (njengasesikhathini senqubo ehhovisi lederm) kungaphepha, ngenkathi ukuvezwa okuphezulu, okuhlala isikhathi eside (njengesikhathi esichithwa phambi kwezikrini) kungahle kube ukufaka isandla ekulimaleni kwe-DNA nokuguga ngaphambi kwesikhathi. Nokho, ucwaningo lusaqhubeka futhi kudingeka izifundo ezinkulu ukuze ziphothulwe ukuze kuvele noma yibuphi ubufakazi obubambekayo.

Ungakuvimbela kanjani ukulimala kwesikhumba ekukhanyeni okuluhlaza okwesibhakabhaka?

Njengoba ukuyeka ngokuphelele ama-smartphones akuyona inketho esebenzayo, nakhu ongakwenza can yenza ukuvimbela konke lokhu kulimala kwesikhumba okuhambisana nokukhanya okuluhlaza okwesibhakabhaka. Ngokwengeziwe, kungenzeka ukuthi usuvele wenza okuningi kwalokhu esimisweni sakho sansuku zonke sokunakekelwa kwesikhumba.

1. Khetha ama-serum akho ngokuhlakanipha. I-serum antioxidant, njengomkhiqizo wokunakekelwa kwesikhumba kavithamini C, ingasiza ekulweni nomonakalo omkhulu, kusho uDkt. Gohara. Uyayithanda i- Isikhumba seMedica System(Thenga It, $ 265, dermstore.com), eyenzelwe ukuvikela ukukhanya okuluhlaza okwesibhakabhaka. (Okuhlobene: Imikhiqizo Engcono Kakhulu Ye-Vitamin C Yokunakekela Isikhumba Yesikhumba Esikhanyayo, Esibukeka Sisebasha)

Enye indlela i-serum eqondene nokukhanya okuluhlaza okwesibhakabhaka, engagqokiswa enye i-serum antioxidant uma ungathanda. Imikhiqizo yeGoodhabit iqukethe i-BLU5 Technology, inhlanganisela ephathelene nezitshalo zasolwandle lokho kuhlose ukubuyisela emuva ukulimala kwesikhumba okwedlule okubangelwe wukukhanya okuluhlaza okwesibhakabhaka kanye nokuvimba ukulimala kwesikhathi esizayo ukuthi kungenzeki, kusho uTrizzino. Zama I-Goodhabit Glow Potion Oil Serum (Thenga It, $ 80, goodhabitskin.com), enikela nge-antioxidant boost futhi inciphise imiphumela emibi yokukhanya okuluhlaza okwesibhakabhaka esikhunjeni.

2. Musa ukugxumela i-sunscreen—sina. Faka i-sunscreen nsuku zonke (yebo, ngisho nasebusika, noma ngabe usendlini), kodwa hhayi nje noma yikuphi isivikelo selanga. "Iphutha elikhulu elenziwa ngabantu ukucabanga ukuthi i-sunscreen yabo yamanje isivele ibavikela," kusho uTrizzino. Esikhundleni salokho, funa isikrini somzimba (aka mineral sunscreen) esinenani eliphakeme le-iron oxide, i-zinc oxide, noma i-titanium dioxide ezithako zalo, ngoba lolu hlobo lwesikrini selanga lusebenza ngokuvimba ukukhanya kwe-UV ne-HEV. I-FYI: Isikrini selanga samakhemikhali sisebenza ngokuvumela ukukhanya kwe-UVA / UVB ukungena esikhunjeni kepha ukusabela kwamakhemikhali bese kuguqula ukukhanya kwe-UV kubude obungonakalisi. Nakuba le nqubo iphumelela ukugwema ukushiswa yilanga noma umdlavuza wesikhumba, ukukhanya okuluhlaza okwesibhakabhaka kusengakwazi ukungena esikhunjeni futhi kubangele umonakalo.

Ama-sunscreen ayadingeka ukuvikela i-UVA / UVB, kepha hhayi ukukhanya okuluhlaza okwesibhakabhaka, ngakho-ke enye inketho ukuthola i-SPF enezithako ezibhekise ngqo lokho kukhathazeka. UDkt Ciraldo unikeza umugqa wemikhiqizo ekhanyayo eluhlaza okwesibhakabhaka, njenge UDkt Loretta Urban Antioxidant Sunscreen SPF 40(Thenga It, $ 50, dermstore.com), enama-antioxidants wokulwa nama-radicals amahhala, i-zinc oxide yokuvikela i-UV, kanye ne-ginseng extract ekhonjiswe ukuthi ivikela ekulimaleni okuvela ekukhanyeni kwe-HEV.
