Izifundo zokulala zisanda kwenziwa ngoba izinto eziningi esizaziyo ngokulala zitholwe kule minyaka engama-25 edlule.
Lolu uhlu lwe amaqiniso ayi-8 athakazelisa kakhulu ngokulala.
1) Irekhodi lenkathi ende kakhulu ngaphandle kokulala liyizinsuku eziyi-11 (amahora angama-264).
Umuntu ubephathwa wukubona izinto ezingekho esimweni esifanele, ukusangana, ukungaboni, nokuphazamiseka kwenkulumo nokukhumbula.
2) Ngokufanelekile, kuthatha imizuzu eyi-10-15 ukulala ngemuva kokulala.

7) Okuningi esikwaziyo ngokulala sikufundile eminyakeni yokugcina ye-25.
8) Ochwepheshe bathi esinye sezitha ezinkulu zokulala ngu Ukutholakala kwe-Intanethi amahora angama-24 ngosuku.
