Ukuphumula okuhle kusiqinisekisa ukuthi sibuyisela amasistimu ethu ukuze abhekane nosuku olulandelayo futhi ngaleyo ndlela asebenze kangcono, afunde kangcono futhi afingqa uzizwe ungcono, kepha ezikhathini eziningi lokhu akulula kangako uma ukucindezeleka kukhona, ngakho-ke ukwazi imithombo yemvelo esivumela ukuthi sizuze ukuphumula kubaluleke kakhulu empilweni yethu futhi i-gelatin ingasisiza ukuyifinyelela.
El ukulala njengamanje kuthinta cishe amaphesenti angama-50 enani labantu emhlabeni ngokusho kwe- Inyuvesi yaseMaryland futhi phakathi kwamaphesenti angama-20 noma angama-30 alabo abathintekile kuzofanele balwe isikhathi esingaphezu konyaka, benenkinga, kepha i-gelatin ingaba nemiphumela emihle yokusiza ngilale ngokwemvelo okungukuthi, ngaphandle kwemiphumela emibi.
Ukulala kuyadingeka ukusiza umzimba ukuzilungisa ngemuva kwemizamo yosuku, kepha eyethu amaphethini okulala kungenzeka ukuthi yathuthuka ngenqubo yokuziphendukela kwemvelo yokuziphendukela kwemvelo, ngoba ekuqaleni yayihlobene nokuzingela ukusinda, okwakungaphepha ukwenziwa emini nokufuna ukuphumula endaweni ephephile ebusuku ukuze ngasikhathi sinye izivikele ezilwaneni ezidla ebusuku.
Ngokusho kwe- University of Washington izilwane eziphansi endaweni ye- uchungechunge lokudlaBavame ukulala kancane kakhulu, ngoba basongelwa ngamathuba amakhulu okudliwa.
Ngokuya ngocwaningo olwenziwa ngo-1998 ku Inyuvesi yase Southern California (San Diego), a ukudla okuphansi kwe-tryptophan ineqhaza ekukhuthazeni ukungeniswa kokulala emadodeni futhi i-gelatin isetshenziswa njengengxenye yokudla okuncane ku-tryptophan, yingakho kuhlobene ukubuyisana kokulala ngokwemvelo.
