NgokweNational Institutes of Health, umuntu omdala ovamile ulala ngaphansi kwamahora ayisikhombisa ebusuku. Kule mpilo yanamuhla ematasa, amahora ayisithupha kuya kwayisikhombisa okulala angazwakala emuhle kakhulu. Noma kunjalo, Ukuthi "usebenza" emahoreni ayisikhombisa okulala akusho ukuthi ngeke uzizwe ungcono kakhulu futhi wenze okwengeziwe uma uchithe ihora noma amabili ngaphezulu embhedeni.
Ngenkathi ukulala kudinga ukwehluka kancane kumuntu nomuntu, iningi labantu abadala abanempilo badinga ukulala amahora ayisikhombisa nohhafu kuya kwayisishiyagalolunye ubusuku ngabunye ukuze basebenze kahle kakhulu. Izingane nentsha zidinga ngisho nangaphezulu (bona idatha engezansi). Futhi yize kunenkolelo yokuthi abantu asebekhulile badinga ukulala okuncane noma ukuthi isidingo sokulala siyancipha ngeminyaka, abantu abadala basadinga okungenani amahora ayisikhombisa nohhafu kuya kwayisishiyagalombili okulala. Kodwa-ke, abantu abadala asebekhulile bavame ukuba nenkinga yokulala ebusuku futhi ukulala phakathi nosuku kungasiza ukugcwalisa isikhala.
Isilinganiso sokulala sidinga ngeminyaka
* Izinsana kuya ezinyangeni ezimbili ubudala: 2 ekuseni kuya ku-12 ntambama
* Izinyanga ezintathu kuya onyakeni owodwa ubudala: 3:1 pm kuya ku-14: 15 pm
* Uneminyaka emithathu kuya kwemihlanu ubudala: 3 ekuseni kuya ku-5 ntambama
* Uneminyaka emithathu kuya kwemihlanu ubudala: 5 ekuseni kuya ku-12 ntambama
* Uneminyaka engu-12 kuya kwengu-18 ubudala: 8,5 kuye kwali-10
* Abantu abadala (18+): 7,5 kuya ku-9 amahora
