Cishe uke wezwa ngomsindo omhlophe okhiqizwe ngokuxuba imisindo yamaza ahlukahlukene. Zivame ukumakethwa njengendlela yokwenza kube lula ukulala. Kodwa-ke, isifundo sikaProfesa Jue Zhang, Ph.D. evela e-University of Beijing (Peking University yaseChina), ikhombisile ukuthi umsindo onegama elihle kakhulu "umsindo obomvana" usiza ukulala ngokushesha okukhulu.
Imisindo ephinki uhlobo lomsindo lapho wonke ama-octave enamandla afanayo, noma amaza afanelana kahle. Cabanga ngomsindo wemvula ewela eceleni komgwaqo, noma umoya ovunguza ngamaqabunga ezihlahla. Igama lalo msindo kungenxa yokuthi ukukhanya okunesibalo esifanayo se-spectral kuzoba nombala obomvana.
Ososayensi abavela eChina banqume ukuthola ukuthi imisindo ephinki ikuthinta kanjani ukulala. Ucwaningo belubandakanya amavolontiya angama-50 abecwiliswe ngenye indlela bethule futhi bevezwa yimisindo ephinki ngesikhathi sokulala ebusuku nasemini, ngenkathi beqopha umsebenzi wabo wobuchopho. Iningi lezifundo - u-75% - liqaphele ukuthi zilala kangcono kakhulu ngemisindo ephinki. Mayelana nokusebenza kobuchopho, izinga "lokulala okuzinzile" - ukulala okuhle kakhulu - lenyuke phakathi kwabahlanganyeli abalala ebusuku ngo-23%, naphakathi kwalabo abalele emini - ngo-45%.
Ucwaningo lukhombisile ukuthi imisindo idlala indima enkulu ekusebenzeni kobuchopho nasekuvumelaniseni amagagasi obuchopho, noma ulele. Umsindo ongapheli wemisindo ephinki uyehlisa futhi ulawula amagagasi obuchopho - uphawu lokulala okunempilo, nokusezingeni.
Ukuze uzizwele ngokwakho, vula imisindo yomoya noma imvula ehlathini ngaphambi kokulala, ubange umsindo oqhubekayo. Ungalanda le misindo njengohlelo lokusebenza kwi-smartphone yakho noma uthenge ithuluzi elincane elikhethekile.
