Imozulu embi, imozulu ebandayo okanye ukufika kwentwasahlobo kukhuthaza abantu abaninzi ukuba bafune ukwenza i-tan. Iikhabhinethi zemitha ye-UVA ayinakuthintelwa kubo bobabini abancinci nabadala, amadoda okanye abasetyhini.
Bambalwa abasiqondayo isizathu sokuba ulusu lwethu lujike lube mdaka, kodwa siyakuqinisekisa ukuba ukusetyenziswa kwaba matshini akuyondlela ilungileyo yokwenza oko.
Zisebenza njani?
Iikhabhathi ze<em>solariums okanye iikhabhinethi zemitha ye-UVA zinezihluzi ezinamandla ezithintela uhlobo lwemitha ye-ultraviolet ye-ultraviolet (eyeyona ichaphazela kakhulu ulusu) kwaye ivumela kuphela uhlobo lwemitha A (ebangela ukutshiswa ngokukhawuleza) kudlule. Nangona imitha ye-UVB imbi kakhulu, imitha ye-UVA ayikho ngasemva. Oku kuchaphazela kakubi imicu ye-elastic yolusu lwakho, kubangela ukuguga kwexesha elide kunye nomonakalo kunye nomngcipheko womhlaza.
I-Solariums ngamagumbi alula asetyenziselwa ukusulwa kwe-cosmetic yangaphakathi. Zikwabizwa ngokuba ziidokodo, izibane zelanga, kunye nezibane zokutshisa. Iikhamera ziindawo ezivaliweyo, ezinezibane eziphezulu, apho umntu anokuba khona ukuma okanye ukulala kangangexesha elithile ukuphembelela isiphumo solusu esifana neso senziwa kukuvezwa kukukhanya kwelanga.
Njengemitha yelanga, imitha yokukhanya ekhutshwa zizibane zesolaria ziqulethe imitha ye-ultraviolet (UV) kwaye ke ngoko ithwele umngcipheko womhlaza kunye nesifo samehlo esihambelana nemitha ye-UV. Nangona kunjalo, imitha ye-UV evela kwizibane ze-solarium igxininise ngakumbi kunemitha yelanga, nto leyo ethetha ukuba imitha ye-UV ekhutshwa zizibane ze-solarium inamandla ngaphezu kwemitha yelanga ekhutshwa lilanga.
Ukongeza kubukhulu obuphezulu, umyinge wemitha yokukhanya ekhutshwa yisolarium eyimitha ye-UV-B (ithelekiswa ne-UV-A kunye ne-UV-C imitha) mkhulu kunomlinganiselo wemitha ye-UV-B ekhutshwa lilanga. Imitha ye-UV-B luhlobo lwemitha ye-UV ebeka umngcipheko omkhulu kwimpilo kwaye inoxanduva loninzi lomhlaza wolusu.
Mngcipheko
Ukufumana i-tan kwezi ntlobo zamadokodo kunokuba neengozi ezininzi zempilo, zombini ixesha elifutshane kunye nexesha elide.
Yandisa ingozi yomhlaza wolusu
Nangona ingeyiyo yodwa ingxaki ebangelwa ziikhabhathi, ngokungathandabuzekiyo yeyona ixhalabisa kakhulu. Izindlu zeX-reyi zonyusa umngcipheko womhlaza, ngakumbi we i melanoma (owona mhlaza wolusu uyingozi).
Ukuzichanaba kwimitha yelanga ngendlela ephakathi, elawulwayo kunye neyokulumkisa akuyongozi. Ewe, kukusebenzisa kakubi oko kutshiswa lilanga, kwaye ukusebenzisa izindlwana zokutshisa ulusu kuyingozi ngakumbi kunokutshiswa lilanga ngokhuseleko.
Ngokutsho kophononongo lweZiko laMazwe ngaMazwe loPhando ngoMhlaza, elapapashwa kwijenali yeLancet Oncology, ukuba uqala ukusebenzisa olu hlobo lokusukwa kwesikhumba phambi kokuba ube neminyaka engama-30 ubudala, umngcipheko wenkangeleko yemelanoma uyanda ukuya kuthi ga kwi-75%, ngenxa yokuba imitha yelanga. iqokelela.
Ukubonakala kwamabala kunye nokuguga kwesikhumba
Njengoko besitshilo ngaphambili, umhlaza wolusu yenye yeengxaki ezininzi ezivela kusetyenziso lwemitha ye-UVA. Ezi zinoxanduva lokukhawulezisa ukuguga kwesikhumba sethu, ukwandisa amabala elanga kunye nokubonakala kwemibimbi. Ngokutsho kweengcali, abantu abahamba kwimizila yokutshisa bathanda ukusebenzisa kakubi ukutshiswa lilanga kwiinyanga zasehlotyeni.
Ukwenza ulusu kubangela ukuguga kwangaphambi kwexesha, ukukhawulezisa inkqubo yendalo yolusu ukuguga. Iimpawu yimibimbi, amabala amnyama okanye amabala obudala, ulusu oluxengaxengayo, kunye nokumila kwesikhumba. Xa ulusu luvezwe kwimitha yelanga eyonakalisayo ye-UV evela kwizindlwana zolusu, iba iphula i-collagen eluswini. I-Collagen igcina ulusu lusempilweni kwaye luncinci lujonge ngokulugcina luqinile.
Ngethamsanqa, ukuguga kwangaphambi kwexesha okubangelwa yimitha ye-UV kuyathintelwa ngokupheleleyo. Kucetyiswa ukuba kuthintelwe iibhedi, izibane kunye namadokodo. Okukhona sintsundu kwaye sitshiswa lilanga, kokukhona siya kuguga ngaphambi kwexesha.
umonakalo wamehlo
Omnye umngcipheko wezindlu zokulukwa ngumonakalo wamehlo obizwa ngokuba photokeratitis, ekwabizwa ngokuba bubumfama bekhephu kuba abantu abaninzi bayayibona kwindawo enekhephu kwiindawo eziphakamileyo. Luhlobo lokutshiswa lilanga esweni. Ezinye izinto ezibangela ifotokeratitis zizibane ezithile ezaphukileyo zolusu kunye nezibane zomphunga wemercury. Iimpawu kukukrazuka, ukubona luzizi, ukuncipha kokubona, ukuvakalelwa kwesanti emehlweni, ukudumba iinkophe kunye neentlungu. Ukuba ufumana oku, bona ugqirha wakho ngesisombululo sesihloko esiza kunceda amehlo akho aphile.
Ukuchaneka kwe-UV kunokubangela urhatyazo, ukonakala kwamehlo okukhokelela ekungaboni kakuhle, kunye nobumfama. Iimpawu ziintlungu ngaphakathi nangaphandle kwamehlo kunye nokubona luzizi okanye amachaphaza.
Ngaba zikhona izibonelelo?
Njengoko nisazi nonke, ukwenza ulusu olukhawulezayo kuko okwenze lo mkhuba waduma. Ezinye iingcali zedermatologists zibhekisela kwinto yokuba kwizigulane ezine-pathologies ezifana ne-psoriasis enzima, ulusu olunzima lwe-atopic okanye i-lymphomas ye-cutaneous, banokuba nemiphumo emihle. Nangona oku kufuneka kunconywe ngugqirha kwaye ungalokothi uwedwa.
Ukukhanya kwe-Ultraviolet kuboniswe ukuba kunezibonelelo ezininzi kwiimeko ezithile zesikhumba. Izixa ezilinganisiweyo zokukhanya kwe-ultraviolet kwi-tanning yangaphakathi iya kunceda ukukhuthaza ukuphiliswa kwamaqhakuva, i-psoriasis kunye ne-eczema. Ukukhanya kwe-UV kunciphisa ukuveliswa kweoli eninzi kunye nokugcina ukulinganisela okunempilo. Ukwasukwa kunceda nokunciphisa inkangeleko yestretch marks.
Abantu abanorhatyana olutyheli kwibala labo banolusu olunenyongo. Isenokuba ngumqondiso weengxaki zesibindi, apho kufuneka ubone ugqirha wakho, okanye umphumo wecala lamayeza. Ukwasulwa ngaphakathi kunokuphucula inkangeleko engafanelekanga yolusu olunejaundice kwaye luncede lubukeke luhlaziyekile kwaye lusempilweni.
Umahluko kunye nokusukwa kwendalo
Nangona abantu abaninzi bezibhenca kwizibane ze-solarium ngenkolelo yokuba babonelela ngendlela ekhuselekileyo yokutshisa kunokutshiswa lilanga, okwangoku akukho bungqina bokuxhasa imbono yokuba i-solarium tanning ikhuselekile. Izindlu zeX-reyi zifunyenwe ukuba zikhupha amanqanaba abukhali ngakumbi emitha I-UV-B kunelanga, kunye nokuvezwa kwimitha ye-UV-B ngokukodwa ngoyena nobangela uphambili weengozi zempilo ezinxulumene nelanga.
Iibhedi zokulukwa zisebenzisa iiglowubhu ze-fluorescent ezikhupha imitha ye-UVA ubukhulu becala, kunye needosi ezincinci ze-UVB. Imitha yeUVA inamandla ngokuphindwe kathathu kunemitha ye-UVA ekukhanyeni kwemvelo kwelanga, kwaye imitha ye-UVB inokusondela ngakumbi kukukhanya kwelanga okuqaqambileyo.
Iisaluni zokulukwa zenza amabango obuxoki ngathi anokunceda ukwenza isiseko setan okanye kudala ivithamin D emzimbeni. Nangona kunjalo, umaleko wesiseko ulingana ne-SPF 4 kwaye sinokuthatha isongezelelo se-vitamin D esilusu. Umhlaza yinto eyoyikisayo kwihlabathi lethu namhlanje, ngoko ke abantu akufuneki benze izinto ezinyusa umngcipheko wokuba lixhoba lawo.
