Xifaniso xa n'wana loyi a'tleleke

Vurhongo i xiyimo xa ntumbuluko xa mihleketo na miri, lexi hlawulekisiwaka hi ku hundzuluxiwa ka mahanyanyele, ku hunguteka ka switwi, kuhunguteka ka matirhele ya mipfimbiti loku sivelaka ku chukunya ka miri lowu etleleke vurhongo.[1][2] Vurhongo bya hambana na ku hanyanya, hileswi byi vangelaka kuhunguteka ka vutihlamuleri bya xivumbiwa eka leswi endlekaka, hambileswi ku nga na ku hambana eka xivumbiwa lexi nga eka khoma, laha vurhongo byi vangelaka matirhele yo hambana ya byongo.

Vurhongo byi rhendzeleka hi kuya hi nkarhi, laha miri wu tikumaka e xikarhi ka minxaka yimbirhi ya vurhongo: Vurhongo lebyi fambelanaka na milorho (REM), na vurhongo byorhula (no-REM). Vurhongo bya milorho byi hlanganisa na ku oma swirho ka nkarhinyana. Evurhongweni, miri wu kota ku tivuyeleta na ku aka masocha ya miri, mipfimbiti, misiha na man'wana ma tirhele ya miri lama pfunaka kutsundzuka, matitwele na swin'wana.[3] Wachi yalendzeni ya miri hi yona yi hlohlotelaka vurhongo navusiku.[4] Tidyondo to tala ti lavisisa xikongomelo na ndlela yo etlela vurhongo. Swiharhi naswona swi xixima nkarhi na ma etlelele ya swona.[5]


Vanhu votala va karhatiwa hi vuvabyi byo hambanahambana byo pfumala vurhongo kumbe ku kuhlwela ku etlela, ku hahama, kufamba famba ukarhi u etle na man'wana mavabyi. Kutala ka timboni ta gezi, swi cince nkarhi wo etlela e matikweni lama ngana tinkomponi to tala.[6]
