Isikhumba sethuingaphansi kwamandla amaningi njengoba sikhula: ilanga, isimo sezulu esibi, kanye nemikhuba emibi. Kodwa singathatha izinyathelo zokusiza isikhumba sethu sihlale sithambile futhi sibukeka sisha.
Ukuthi isikhumba sakho sizoguga kanjani kuzoncika ezintweni ezahlukahlukene: indlela yakho yokuphila, ukudla, ufuzo, kanye neminye imikhuba yakho. Isibonelo, ukubhema kungakhiqiza ama-free radicals, ama-molecule e-oxygen ayenempilo ngaphambili angasebenzi ngokweqile futhi angazinzile. Ama-free radicals alimaza amangqamuzana, okuholela, phakathi kwezinye izinto, emibimbi ngaphambi kwesikhathi.
Kukhona nezinye izizathu. Izinto eziyinhloko ezibangela isikhumba esinamabala acwebezelayo zifaka phakathi ukuguga okuvamile, ukuchayeka elangeni (ukushaqeka kwesithombe) kanye nokungcola, kanye nokulahlekelwa ukwesekwa okungaphansi kwesikhumba (izicubu ezinamafutha phakathi kwesikhumba sakho nemisipha). Ezinye izinto ezibangela ukuguga kwesikhumba zifaka phakathi ukucindezeleka, amandla adonsela phansi, ukunyakaza kobuso kwansuku zonke, ukukhuluphala, ngisho nesimo sokulala.
Yiziphi izinhlobo zezinguquko zesikhumba eziza nokukhula?
- Njengoba sikhula, izinguquko ezinjengalezi zenzeka ngokwemvelo:
- Isikhumba siba lukhuni.
- Isikhumba sikhula izilonda ezifana nokuqala kwezimila.
- Isikhumba siyaxega. Ukulahlekelwa yizicubu ezinwebekayo (i-elastin) esikhumbeni njengoba sikhula kwenza isikhumba silenga kalula.
- Isikhumba siba sobala kakhudlwana. Lokhu kubangelwa ukuncishiswa kwe-epidermis (ungqimba olungaphezulu lwesikhumba).
- Isikhumba siba buthakathaka kakhulu. Lokhu kubangelwa ukuthamba kwendawo lapho i-epidermis kanye ne-dermis (ungqimba lwesikhumba ngaphansi kwe-epidermis) kuhlangana khona.
- Isikhumba siba nokuphuka kalula. Lokhu kungenxa yezindonga zemithambo yegazi ezinciphile.
