Iintlungu zangasemva zingalala ngakumbi umatrasi onzima? - - - - - - - - - - - - Umzi mveliso woomatrasi

Umzi-mveliso woomatrasi waziswa ixesha elide, wonke umntu wayecinga, malunga nezo ntlungu zindala zokukhwaza, eyona bhedi inzima yokulala, ukuba ufuna ukwenza ibhedi ye-simmons, kufuneka ulale umqamelo onzima kakhulu. Ukuqinisekisa ukuba esi siko sinenyaniso yesayensi, izazinzulu zaseSpain kutshanje zenze umfuniselo ofanelekileyo. Iziphumo zovavanyo ziqinisekisa ukuba kwizigulane ezineentlungu zangasemva, uninzi lunokunciphisa uhlobo lwazo lwe-ache mat ye-medium hardness, ngokuqhelekileyo kuthiwa kunokuba nzima kwinqanaba lebhodi. Bathi abaphandi bachaza, umzi-mveliso woomatrasi ngenxa yokuba umqamelo onzima kuwo wonke umzimba ukubonelela ngenkxaso efanelekileyo, ngoko oogqirha bahlala bekhuthaza izigulana ezibuhlungu zisebenzisa i-cushion enzima. Uvavanyo lungqina, nangona kunjalo, malunga nokukhulula iintlungu zangasemva ngokwazo, ikhetha i-mat kufuneka ibe bubunzima obuphakathi, ingabi nzima kakhulu. Abaphandi bathi isinqe sesinye sezona ndawo zingenangxaki kwilungu ngalinye lomzimba womntu. Uninzi lwabantu ngexesha elithile ebomini babo, okanye ngenxa yokulimala, okanye ngokusebenzisa isinqe ngengozi, okanye ngenxa yengozi, baya kushiya iimpawu zentlungu emva. Umntu okhanyayo, wenzakala iintsuku ezimbalwa, umntu obunzima, unokuqaqamba kwiinyanga okanye iminyaka, umzi-mveliso woomatrasi ude ube nexhala lobomi bonke malunga nengxaki. Kunye, bambalwa kakhulu abantu abaziyo ukuba imali oyichithile kunyango lomqolo iyamangalisa. Nyaka ngamnye abantu baseMelika, umzekelo, imali echithwa kunyango lomqolo ixabisa ukuya kutsho kwiibhiliyoni ezingama-50 zeerandi. Abaphandi baseSpain benziwe kwizigulane ezingama-313 ezineentlungu ze-lumbar zilala umqamelo onzima okanye ubunzima obuphakathi bovavanyo lokuchasana kwe-mat. Bacele aba bafundi ukuba bazame ukulala, ukukhetha umzi-mveliso we-cushion umatrasi kwaye emva koko kubaphandi bachaza ubusuku bokulala kwaye bavuke ekuseni xa besinqeni siziva ngokweenkcukacha. Kwiiveki ezintathu kamva, kunye ne-cushion enzima echazwe ngokwahlukileyo, ukhetho lwezigulane ezinobunzima obuphakathi obuchazwe esinqeni esibuhlungu sinciphisa kakhulu, ukuvuka ngeqondo elilula kunokuphucula okucacileyo. , abaphandi bathi i-factory ye-mattress isebenzisa ubulukhuni obuphakathi kwe-mat i-cushion enzima kakhulu inokuphucula izigulane ezininzi ezibuhlungu ukubonakaliswa kwekliniki. Nangona yonke i-cushion enzima inokuxhasa ngokufanelekileyo umzimba womntu, kodwa iqondo layo elomeleleyo lithintela i-mat ngokwayo ngomqolo phakathi kwe-radian yendalo ehambelana kakhulu nomzimba womntu. Ngaloo ndlela, oogqirha kwizigulane ezibuhlungu ezichazwe ngohlobo lwe-mat, kufuneka zibe nomonde kunye nobunzima obuphakathi be-mat. Kweli phepha, yingqokelela yemveliso yoomatrasi
