Phakathi kwemisongo engapheliyo yeTikTok ngaphambi kokuba uvuke kusasa, iiyure ezisibhozo zomsebenzi kwikhompyuter, kunye neziqendu ezimbalwa kwiNetflix ebusuku, kukhuselekile ukuba uchitha uninzi lomhla wakho phambi kwescreen. Ngapha koko, ingxelo yakutshanje yaseNielsen yafumanisa ukuba abantu baseMelika bachitha phantse isiqingatha sosuku lwabo-iiyure ezili-11 ukuba zichaneke — kwisixhobo. Ukulunga, eli nani likwabandakanya ukusasaza umculo kunye nokumamela iipodcasts, kodwa iyothusa (nangona ayingothusi kwaphela) inxalenye yobomi bakho bemihla ngemihla.

Phambi kokuba ucinge ukuba le izakuguquka ibe "yibeke phantsi ifowuni yakho", yazi ukuba ixesha lescreen alikho mbi lonke; Lunxibelelwano lwentlalo kunye namashishini axhomekeke kwitekhnoloji yokwenza ishishini-heck, eli bali alinakubakho ngaphandle kwezikrini.

Kodwa inyani yeyokuba lonke elo xesha lesikrini lichaphazela kakubi ubomi bakho ngokucacileyo (ubuthongo bakho, inkumbulo, kunye nemetabolism) kunye neendlela ezingaziwayo (ulusu lwakho).

Ngokucacileyo iingcali (kunye nomama wakho) ziya kukuxelela ukuba unciphise ixesha lakho lesikrini, kodwa kuxhomekeke kumsebenzi wakho okanye indlela yokuphila enokuthi ingenzeki. "Ndicinga ukuba kufuneka samkele itekhnoloji kunye nazo zonke iindlela ezintle zokuphucula ubomi bethu. Qiniseka nje ukuba ukhusela ulusu lwakho ngelixa usenza, utshilo uJeniece Trizzino, usekela-mongameli wophuhliso lwemveliso eGoodhabit, uphawu olutsha lokhathalelo lolusu olwenziwe ngokuthe ngqo ukulwa nemiphumo yokukhanya okuluhlaza okwesibhakabhaka.

Funda ukuze uqonde ngcono ifuthe lokukhanya okuluhlaza okwesibhakabhaka kwizixhobo zakho elinokuba nalo kulusu lwakho kunye nento onokuyenza ukuyithintela. (Eyeleleneyo: Iindlela ezi-3 zefowuni yakho ezonakalisa ulusu lwakho kunye nento omawuyenze ngayo.)

Yintoni ukukhanya okuluhlaza okwesibhakabhaka?

Iliso lomntu liyakwazi ukubona ukukhanya njengemibala ethile xa kubetha ubude obuthile. Ukukhanya okuluhlaza okwesibhakabhaka luhlobo lokukhanya olukhupha ukukhanya okuphezulu kwamandla (HEV) okuhlala kwindawo eluhlaza okwesibhakabhaka esibonakalayo esibonakalayo. Ngokomxholo, ukukhanya kwe-ultraviolet (UVA/UVB) kukwi-spectrum yokukhanya okungabonakaliyo kwaye kunokungena kuluhlu lokuqala nolwesibini lwesikhumba. Ukukhanya okuluhlaza kunokufikelela kuyo yonke indlela ukuya kumaleko wesithathu, utshilo uTrizzino.

Kukho imithombo emibini ephambili yokukhanya okuluhlaza okwesibhakabhaka: ilanga kunye nezikrini. Ilanga ngokwenene linokukhanya okuluhlaza okwesibhakabhaka ngakumbi kune-UVA kunye ne-UVB zidityanisiwe, utshilo uLoretta Ciraldo, MD, ugqirha wesikhumba eMiami. (PS Ukuba uyazibuza: Ewe, ukukhanya okuluhlaza okwesibhakabhaka sisizathu sokuba ubone isibhakabhaka njengombala oluhlaza okwesibhakabhaka.)

Zonke izikrini zedijithali zikhupha ukukhanya okuluhlaza okwesibhakabhaka (i-smartphone yakho, iTV, ikhompyutha, ithebhulethi, kunye ne-smartwatch) kwaye umonakalo usekelwe ekusondeleni kweso sixhobo (ubuso bakho busondele kangakanani kwisikrini) kunye nobukhulu besixhobo, utsho uTrizzino. Kukho impikiswano ejikeleze ubungakanani kunye nokukhanya kokukhanya okuqala ukubangela umonakalo, kwaye akucaci ukuba uninzi lokukhanya kwakho okuluhlaza okwesibhakabhaka kuvela elangeni kuba ngumthombo onamandla, okanye izikrini ngenxa yokusondela kwabo kunye nexesha lokusetyenziswa.

Ukukhanya okuluhlaza kunokuchaphazela njani ulusu?

Ubudlelwane phakathi kokukhanya okuluhlaza kunye nolusu bunzima. Ukukhanya okuluhlaza kuye kwafundiswa ukuba kusetyenziswe kwidermatology ukunyanga iimeko zolusu, ezifana ne-acne okanye i-rosacea. (USophia Bush ufunga ngonyango oluhlaza okwesibhakabhaka kwi-rosacea yakhe.) Kodwa uphando olutsha luye lwaphakamisa ukuba ukukhanya okuphezulu, ixesha elide ekukhanyeni okuluhlaza kunokunxulunyaniswa neemeko zolusu ezingaphantsi, ezifana nokuvezwa kwe-UV. ukukhanya. Kucingelwa ukuba ukukhanya okuluhlaza okwesibhakabhaka, njenge-UV, kunokwenza radicals simahla, ekukholelwa ukuba ngunobangela wawo wonke loo monakalo. Iiradicals zasimahla ngamasuntswana ezithambiso amancinci adala umonakalo eluswini, njengokujika kombala kunye nemibimbi, utshilo uMona Gohara, M.D., ugqirha wesikhumba kunye nonjingalwazi onxulumene neklinikhi kwiYale School of Medicine.

Olunye uphononongo luye lwabonisa ukuba imveliso ye-melanin eluswini iphindaphindwe kabini kwaye yaqhubeka ixesha elide xa ibonakaliswe kukukhanya okuluhlaza xa kuthelekiswa ne-UVA. Ukunyuka kwamanqanaba e-melanin kungakhokelela kwimicimbi ye-pigmentation efana ne-melasma, indawo yobudala, kunye neendawo ezimnyama emva kokuphuma. Kwaye xa abahloli bevezwa ukukhanya okuluhlaza okwesibhakabhaka kwaye ke ngokwahlukileyo kwi-UVA, kwakukho ubomvu obuninzi kunye nokuvuvukala kwesikhumba kubonakaliswe ekukhanyeni okuluhlaza okwesibhakabhaka kunomthombo wokukhanya we-UVA, utsho uDkt Ciraldo.

Ukubeka ngokulula: Xa uvezwe kukukhanya okuluhlaza okwesibhakabhaka, ulusu lwakho luyaxinezeleka, olubangela ukudumba kwaye lukhokelele kumonakalo weselula. Ukonakala kweeseli zolusu kukhokelela kwiimpawu zokuguga, ezinje ngemibimbi, amabala amnyama, kunye nelahleko ye-collagen. Ngeendaba ezimnandi: Akukho datha yokucebisa unxibelelwano phakathi kokukhanya okuluhlaza kunye nomhlaza wolusu.

Ubhidekile malunga nokuba ukukhanya okuluhlaza kubi okanye kulungile? Kubalulekile ukuba uqaphele ukuba zombini ezi zinto zithathiweyo ziyinyani: Ukuvezwa kwexesha elifutshane (njengaxa kusenziwa inkqubo kwiofisi yederm) kunokukhuseleka, ngelixa ukubonakaliswa okuphezulu, kwexesha elide (njengexesha elichithwe phambi kwezikrini) kunokuba igalelo kumonakalo weDNA kunye nokuguga ngaphambi kwexesha. Nangona kunjalo, uphando lusaqhubeka kwaye kufuneka izifundo ezikhulu ukuba zigqitywe ngenxa yobungqina obuqinisekileyo bokuvela.

Unokuthintela njani umonakalo wesikhumba ekukhanyeni okuluhlaza okwesibhakabhaka?

Kuba ukulahla ii-smartphones ngokupheleleyo ayisiyiyo inketho enokwenzeka, nantsi into oyenzayo unako yenza ukuthintela wonke lo monakalo wolusu onxulunyaniswa nokukhanya okuluhlaza okwesibhakabhaka. Ukongeza, usenokuba sele uyenza le nto kwindlela yakho yemihla ngemihla yokunyamekela ulusu.

1. Khetha iiserum zakho ngobulumko. I-serum ye-antioxidant, efana ne-vitamin C yemveliso yokunyamekela ulusu, inokunceda ukulwa nomonakalo ongenayo i-radical, utsho uGqirha Gohara. Uyayithanda Inkqubo yoLusu lweMedica(Yithenge, $ 265, dermstore.com), eyenzelwe ukukhusela ukukhanya okuluhlaza okwesibhakabhaka. (Inxulumene: Ezona mveliso ziLungileyo zeVitamin C zoKhathalelo lolusu oluKhanyayo, uLusu oluKhangela eLutsha)

Enye inketho yiserum yokukhanya okuluhlaza okwesibhakabhaka, enokuthi ifakwe enye i-serum ye-antioxidant ukuba uyathanda. Iimveliso zeGoodhabit ziqulethe i-BLU5 Technology, indibaniselwano yobunini bezityalo zaselwandle ejolise ekubuyiseleni emva ulusu oludlulileyo olubangelwe kukukhanya okuluhlaza okwesibhakabhaka kunye nokuvimba umonakalo wexesha elizayo ukuba ungenzeki, utshilo uTrizzino. Zama Goodhabit Glow Potion Oyile Serum (Thenga, i-$ 80, i-goodhabitskin.com), enika i-antioxidant boost kunye nokunciphisa iziphumo ezibi zokukhanya okuluhlaza okwesibhakabhaka esikhumbeni.

2. Musa ukutsiba isikhuselo-langa—ngokunzulu. Faka isicelo se-sunscreen yonke imihla (ewe, nasebusika, naxa ungaphakathi endlwini), kodwa hayi kuphela nayiphi na i-sunscreen. “Eyona mpazamo inkulu abantu abayenzayo kukucinga ukuba i-sunscreen yabo sele ibakhusela,” utshilo uTrizzino. Endaweni yoko, khangela i-sunscreen ebonakalayo (ene-sunscreen) enexabiso eliphezulu le-iron oxide, i-zinc oxide, okanye i-titanium dioxide kwizithako zayo, kuba olu hlobo lwe-sunscreen lusebenza ngokuthintela ukukhanya kwe-UV kunye ne-HEV. I-FYI: I-sunscreen ye-Chemical isebenza ngokuvumela ukukhanya kwe-UVA/UVB ukuba kungene esikhumbeni kodwa ukusabela kweekhemikhali emva koko kuguqule ukukhanya kwe-UV ibe yi-wavelength engonakalisiyo. Ngelixa le nkqubo isebenza ngokufanelekileyo ukunqanda ukutshiswa lilanga okanye umhlaza wolusu, ukukhanya okuluhlaza okwesibhakabhaka kusakwazi ukungena esikhumbeni kwaye kubangele ukonakala.

I-sunscreens iyadingeka ukukhusela kwi-UVA / UVB, kodwa kungekhona ukukhanya okuluhlaza okwesibhakabhaka, ngoko ke enye inketho kukufumana i-SPF enezithako ezijolise ngokukodwa loo nkxalabo. UGqirha Ciraldo ubonelela ngomgca weemveliso ezikhanyayo eziluhlaza, ezinje nge UGqr. Loretta Urban Antioxidant Sunscreen SPF 40(Thenga, i-$ 50, i-dermstore.com), ene-antioxidants ukulwa ne-radicals yamahhala, i-zinc oxide yokukhusela i-UV, kunye nesicatshulwa se-ginseng esiye saboniswa ukukhusela umonakalo ovela kukukhanya kwe-HEV.

3. Yongeza ezinye izincedisi kubuchwepheshe bakho. Cinga ngokuthenga icebo lokucoca ukukhanya okuluhlaza okwesibhakabhaka kwiikhompyuter kunye neetafile, okanye ukunciphisa isetingi yokukhanya eluhlaza okwesibhakabhaka kwifowuni yakho (ii-iPhones zikuvumela ukuba ucwangcise ukutshintsha kobusuku ngale njongo), utshilo uGqirha Ciraldo. Unakho nokuthenga iiglasi zokukhanya eziluhlaza ukunceda ukuthintela uxinzelelo lwamehlo kunye nomonakalo kwimpilo yamehlo akho, kodwa ukuthintela phantsi kwemibimbi yamehlo kunye ne-hyperpigmentation, uyongeza.
