Khungu louma ndi khungu lomwe limakhudza anthu mosiyanasiyana. Nthawi zambiri si nkhani yaikulu. Nthawi zina anthu ena amakhala ndi khungu lofewa kapena lofewa lomwe limachokera kumapweya wabwino. Ena amatha kuthamanga ndi kuyabwa kwambiri moti samakhala omasuka ndipo amakhudza kugona kwawo.
Zambiri mwa zifukwa za khungu louma zomwe zili m'munsizi zimakhudza stratum corneum : pamwamba pake ya epidermis . Chingwe cha corneum chimagwira ntchito ngati pulasitiki kukulunga thupi lonse mwa kusunga zinthu zowononga ndi majeremusi kunja ndikusunga madzi ndi mafuta mkati, kupanga khungu lofewa ndi labwino.
Musanafike ku malo omwe mumawakonda kwambiri, onani ngati chimodzi mwazifukwa zisanu ndi ziwirizi chikhoza kukhala mlandu pa khungu lanu louma.
Zaka
Ukalamba ndi chimodzi mwa zomwe zimayambitsa khungu louma. Pamene tikukalamba matenda a epidermis amakhala ofooka ndipo chimbudzi cha corneum sichitha madzi ochulukirapo. Anthu ambiri amayamba khungu louma mu 50s; ndi zaka za m'ma 60, pafupifupi aliyense ali ndi khungu lachinyontho. Tsoka ilo, n'kosapeweka.
Nyengo
Chimake chimakhudza kwambiri khungu. Kawirikawiri, khungu limakhala lotentha kwambiri m'nyengo yozizira pamene kutentha ndi mvula zimataya, ndipo mphepo yozizira imayamwa chinyezi pakhungu. Nyengo yozizira imafunanso kutentha komanso nthawi yochulukirapo m'nyumba, zomwe zimamvanso khungu. Kutentha kwapakati, kutentha kwa malo, ndi moto zomwe zimapangitsa kuti thupi lizizira.
Mosiyana ndi nyengo, ngakhale nyengo yamadera ofunda angayambitse khungu louma. Mwachitsanzo, dera lachipululu lingakhale ndi kutentha kwakutentha, koma imakhalanso ndi madzi otsika, omwe amachititsa khungu la chinyezi.
Kutuluka kwa dzuwa
Kutentha kwa dzuwa mu nyengo iliyonse kungathe kuuma khungu. Mazira a UV amatsika kwambiri pansi pa khungu, zomwe zimapangitsanso makwinya ndi kuphulika kupatula kuuma. Kutentha kwa dzuŵa kumauma khungu mwa kuchepetsa kulemera kwake kwa mafuta.
