• Ukukhanya kwelanga nempilo yengqondo
• Izinzuzo ezengeziwe zelanga
• Ukwakha amathambo aqinile
• Ukuvimbela umdlavuza
• Ukuphulukisa izimo zesikhumba
• Izimo ezingeziwe
• Ukukhanya kwelanga nokulinganisela
• Umbono

Sifaka imikhiqizo esicabanga ukuthi ilusizo kubafundi bethu. Uma uthenga ngezixhumanisi ezikuleli khasi, singathola ikhomishini encane. Nansi inqubo yethu.

Ukukhanya kwelanga ne-serotonin

Sijwayele ukuzwa ukuthi imisebe yelanga efudumele ingakanani engaba yingozi esikhunjeni sakho.Kepha bewazi ukuthi ibhalansi elungile ingaba nezinzuzo eziningi zokuphakamisa imizwa?

Ukukhanya kwelanga nobumnyama kubangela ukuphuma kwamahomoni ebuchosheni bakho. Ukuvezwa yilanga kucatshangwa ukuthi kukhulisa ukukhululwa kobuchopho kwehomoni ebizwa nge-serotonin. ISerotonin ihlotshaniswa nokukhulisa imizwa nokusiza umuntu ukuthi azizwe ezolile futhi egxile. Ebusuku, ukukhanya okumnyama kudala ingqondo ukuthi yenze enye i-hormone ebizwa nge-melatonin. Le hormone inesibopho sokukusiza ulale.

Ngaphandle kokuchayeka ngokwanele elangeni, amazinga akho e-serotonin angacwila. Amazinga aphansi e-serotonin ahlotshaniswa nengozi ephezulu yokudangala okukhulu ngephethini yonyaka (eyayaziwa ngaphambili njengesifo sonyaka noma i-SAD). Lolu uhlobo lokudangala olubangelwa ukuguquguquka kwezinkathi zonyaka.

Ukuqiniswa kwemizwa akusona ukuphela kwesizathu sokuthola inani elinyukayo lokukhanya kwelanga. Kunemihlomulo eminingana yezempilo ehlotshaniswa nokubamba inani elilinganiselwe lemisebe.

Ukukhanya kwelanga nempilo yengqondo

Ukwehla kokushiswa yilanga kuhlotshaniswe nokwehla kwamazinga akho e-serotonin, okungaholela ekucindezelekeni okukhulu ngephethini yonyaka. Imiphumela eyenziwe ukukhanya kwe-serotonin idalwa yilanga elingena ngeso. Ukukhanya kwelanga kukhomba izindawo ezikhethekile ku-retina, okubangela ukukhishwa kwe-serotonin. Ngakho-ke, kungenzeka ukuthi uhlangabezane nalolu hlobo lokudangala esikhathini sasebusika, lapho izinsuku zifushane.

Ngenxa yalokhu kuxhumeka, enye yezindlela zokwelapha eziyinhloko zokudangala ngephethini yonyaka ukwelashwa okulula, okwaziwa nangokuthi i-phototherapy. Ungathola ibhokisi lokwelashwa elikhanyayo onalo ekhaya. Ukukhanya okuvela ebhokisini kulingisa ukukhanya kwelanga okungokwemvelo okushukumisa ubuchopho ukuthi benze i-serotonin futhi kunciphise i-melatonin eyeqile.

Ukuvezwa yilanga kungasiza nalabo abane:

• ezinye izinhlobo zokucindezeleka okukhulu
• i-premenstrual dysphoric disorder (PMDD)
• abantu abakhulelwe abanengcindezi

Izinkinga ezihlobene nokukhathazeka nokuhlaselwa uvalo nakho kuye kwaxhunyaniswa nokushintsha kwezinkathi nokuncipha kwelanga.

Izinzuzo ezengeziwe zelanga

Izinzuzo zelanga zidlula ukulwa nokuxineka. Okulandelayo ngezinye zezizathu zokubamba eminye imisebe:

Ukwakha amathambo aqinile

Ukuchayeka emisebeni ye-ultraviolet-B emisebeni yelanga kudala ukuthi isikhumba somuntu senze uvithamini D. Ngokusho, esikhathini esiyimizuzu engama-30 ngenkathi ugqoke isudi, abantu bazokwenza amazinga alandelayo kavithamini D:

• Amayunithi angama-50 000 amazwe ngamazwe (ama-IU) kubantu abaningi baseCaucasus
• Ama-IU angama-20,000 kuya kwangama-30,000 kubantu abashukiwe
• Ama-IU angama-8,000 kuya ku-10,000 kubantu abanesikhumba esimnyama

Uvithamini D wenza ukubonga ilanga lidlala indima enkulu empilweni yethambo. Amazinga aphansi kavithamini D axhunywe kuma-rickets ezinganeni nasezifweni ezichitha amathambo njenge-osteoporosis ne-osteomalacia.

Ukuvimbela umdlavuza

Yize ukukhanya kwelanga okweqile kungafaka umdlavuza wesikhumba, inani elilinganisiwe lokukhanya kwelanga empeleni kunezinzuzo zokuvimbela uma kukhulunywa ngomdlavuza.

Ngokusho kwabaphenyi, labo abahlala ezindaweni ezinamahora ambalwa okukhanya kwelanga basemathubeni amaningi okuba nomdlavuza othile kunalabo abahlala lapho kunelanga elithe xaxa emini. Lawa mdlavuza afaka:

• umdlavuza wamathumbu
• I-lymphoma kaHodgkin
• umdlavuza we-ovari
• umdlavuza wepancreatic
• umdlavuza wendlala yabesilisa

Ukuphulukisa izimo zesikhumba

Ngokusho kwelanga, ukuvezwa yilanga kungasiza ekwelapheni izimo zesikhumba eziningana, futhi. Odokotela bancome ukutholakala kwemisebe ye-UV ukwelapha:

• ukhwekhwe
• eczema
• i-jaundice
• induna

Ngenkathi ukwelashwa okulula kungewona wonke umuntu, udokotela wesikhumba angancoma ukuthi ukwelashwa okulula kuzokusiza yini ukukhathazeka kwakho kwesikhumba.

Izimo ezingeziwe

Izifundo zocwaningo ziveze ukuxhumana kokuqala phakathi kwelanga njengokwelashwa okungenzeka kwezinye izimo eziningana. Lokhu kufaka phakathi:

• isifo samathambo (RA)
• uhlelo lupus erythematosus
• ukuvuvukala kwamathumbu
• I-thyroiditis

Kodwa-ke, kufanele kwenziwe izifundo eziningi ngaphambi kokuba abacwaningi baphethe ngokuthi ukukhanya kwelanga kungaba ukwelashwa kwalezi zimo nezinye.

Ukukhanya kwelanga nokulinganisela

Ngenkathi kunezizathu eziningi ezinhle zokuthola ilanga, ilanga likhipha imisebe ye-ultraviolet (UV). Imisebe ye-UV ingangena esikhunjeni futhi ilimaze i-DNA yeseli. Lokhu kungaholela kumdlavuza wesikhumba.

Abaphenyi abahlali benesilinganiso esiqondile sokuthi kufanele uhlale ngaphandle isikhathi esingakanani ukuze uzuze izinzuzo zokukhanya kwelanga. Kodwa ukuchaza inani elithe xaxa lokuchayeka elangeni kuya ngohlobo lwesikhumba sakho nokuthi imisebe yelanga iqonde kangakanani.

Abantu abanesikhumba esikhanyayo bavame ukushiswa yilanga ngokushesha kunalabo abanesikhumba esimnyama. Futhi, maningi amathuba okuthi ukushiswa yilanga kuphumele ngaphandle lapho imisebe yelanga iqonde kakhulu. Lokhu kuvame ukwenzeka phakathi kuka-10 ekuseni no-4 ntambama.

Ngokusho, ukuthola noma yikuphi ukusuka emaminithini ama-5 kuye kwangama-15 elanga ezandleni zakho, ezandleni, nasebusweni izikhathi ezingama-2-3 ngeviki kwanele ukujabulela izinzuzo zelanga zokukhulisa ivithamini D. Qaphela ukuthi ilanga kumele lingene esikhunjeni. Ukugqoka i-sunscreen noma okokugqoka esikhumbeni sakho ngeke kuholele ekukhiqizeni uvithamini D.

Kodwa uma uzoba ngaphandle ngaphezu kwemizuzu engu-15, kuwumqondo omuhle ukuvikela isikhumba sakho. Ungakwenza lokho ngokufaka i-sunscreen ene-sun protection factor (SPF) okungenani engu-15. Ukugqoka isigqoko esivikelayo nehembe nakho kungasiza.

Umbono

Kusukela ekwelapheni izimo zesikhumba kuye ekuthuthukiseni imizwa, ukukhanya kwelanga kunezinzuzo eziningi. Uma uhlala ezindaweni eziphakeme ezinokukhanya kwelanga okuncane, ibhokisi elikhanyayo linganikeza ezinye zezinzuzo zalo zokukhulisa imizwa.

Ngenxa yokuthi ukuvezwa yilanga ngokweqile kuhlotshaniswa nengozi yomdlavuza wesikhumba eyandisiwe, ungahlali ngaphandle isikhathi eside ngaphandle kwesikrini selanga. Uma uzoba ngaphandle isikhathi esingaphezu kwemizuzu engu-15 noma kunjalo, uzodinga i-sunscreen ene-SPF okungenani engu-15.
