Ukulala kwe-buoyancy kunye nophando lwezonyango

Ubuthongo be-buoyancy kunye ne-buoyancy yophando lwezonyango

ubuthongo obusisiseko kunye nayo yonke inkxaso kunye nokubonelela ngokujikeleza kwegazi okulungileyo kunye nokulala okunempilo ngakumbi kunye nokuzinza ngakumbi, izifundo zonyango zibonise ukuba i-buoyancy yamanzi kune-avareji yebhedi ye-mattress kunye ne-spring mattress kulula ukwenza abantu balale, ibhedi yamanzi ibonelela ngokulala okunempilo kunye nokukhululeka, le bhedi yamanzi kukunceda ukukhangela iingxaki zempilo zexesha elide, kuquka ukunyamekelwa kwesigulane kunye nonyango.

abaphandi bezonyango babika enye ibhalansi yamanzi ebhedi yomzimba yinzuzo yethambo kunye nokunciphisa uxinzelelo lwemisipha ukuvumela ukujikeleza kwegazi okungcono. Umatrasi wenza ibhedi yamanzi inokunciphisa ibhedi eqinileyo yabalalayo ngobusuku obunye emva kokuba umzimba uyibuyisela amaxesha angama-30 ukuya kwangama-50. Kwaye abanye abadingi bhedi yokujula nokujika bonke aba buthongo kuya kuthoba ixesha lokulala, lo mhlathi wexesha lelona xesha lokuphumla kwaye lelona xesha lilungileyo lokubuyisela ukudinwa kwethu kwengqondo. Uvavanyo kwiyunivesithi yaseChicago kwiziko lezonyango imisipha ye-matrasi jikelele ithwala uxinzelelo lobunzima bomzimba, i-hip yi-80 millimeters ye-mercury, isithende yi-6 millimeter mercury, i-mercury column umlenze 45 mm, umlenze ophantsi we-45 millimeters ye-mercury, umva we-80 millimeters ye-mercury enye i-2 ye-mercury ye-mercury, i-2 ye-mercury enye inxalenye ye-mercury ye-mercury.

enye ISEBENZA ibhedi yamanzi ingqalelo yezonyango yimpilo, ukufuma iibhaktheriya permeability kwaye akayi kubangela ukucaphuka ulusu, umatrasi jikelele kulula ukufunxa uthuli kunye nokufuma, ezele ziibhaktheriya unako ngokucokisekileyo ukuhlamba ukhuko lwamanzi, angosulelwanga, okoko nje ukusetyenziswa kokucoca iyeza lolwelo lwe-disinfection okanye isicoci sendlu. Usenokuba ufumanise ukuba izibhedlele ezininzi zaqala ukusebenzisa ibhedi yamanzi njengamathambo oomatrasi abakhubazekileyo wokubuyisela kwimeko yesiqhelo, ekwayilelwe ukuba isetyenziswe kwiibhedi zesibhedlele.

kwisiseko seyunivesithi yaseWisconsin esibhedlele ngo-1986, ngokwengxelo ngo-Oktobha 12, ibhedi iingxaki skeletal emzimbeni womntu, bedsore, neurasthenia, samathambo, iintlungu kwezihlunu, izandla kunye neenyawo acid hemp, umqobo kwegazi, endocrine hayi ukuxubana, ukuphuthelwa, uxinzelelo lwegazi oluphezulu, uxinzelelo lwemithambo-luvo njalo njalo kunomphumela wokunciphisa isiphumo sokuphulukisa iziyobisi.

Ingxelo yabonisa ngakumbi ukuba umahluko phakathi kwebhedi yamanzi kunye ne-spring mattress yokuxhasa ibhedi yamanzi kunye nokudada umzimba wonke ngokulinganayo kunye ne-spring mattress ayikwazi. Umatrasi owenziwe kumandlalo wamanzi adadayo ngokokulala komzimba womntu igophe lendalo liconcave kunye neconvex, umatrasi wasentwasahlobo akunjalo. Umandlalo wamanzi unokuxhasa umqolo ophantsi womzimba ( Umva womzimba womntu indawo emxinwa) Le nxalenye yinxalenye efuna ukuxhaswa, i-mattress yasentwasahlobo engazinzanga, 'ibhalansi iqulunqwe ngumzimba xa ibhedi yamanzi yokulala yenye yezona zinto zibalulekileyo kwimpilo yomzimba womntu, kuba i-mattress yasentwasahlobo ngaphandle kolu phawu.

Ukongeza ikwaxhasa izibonelelo zebhedi yamanzi kukuba ingakwazi & lt; Thermostat & gt; Isiphumo sokudlulisa ubushushu, yenza umzimba uzive ushushu, ubushushu & lt; Ubushushu & gt; Unyango lobushushu lusetyenziswa kakhulu esibhedlele, ngoko ke yiba nobushushu bokungena, vuyisa abantu ukuba ubushushu abukwazi kutshintshwa ngomnye umatrasi. Ngokufanayo kwimozulu eshushu, ibhedi yamanzi inokwenza umntu azive epholile kwaye ehlaziyekile, kuba ubushushu obulungelelanisiweyo benza umzimba ukhululeke.

uvavanyo lwezonyango lubonise ukuba umandlalo wamanzi ubonelela ngokuzinza ngakumbi, ukhululekile ngakumbi, ngaphezu kombhede oqhelekileyo ongaphazamiseki ubuthongo, kwaye ube nokujikeleza kwegazi okungcono kunye nokukhusela umphumo wethambo.

zonke iingxelo zonyango zibonakalisa ibhedi yamanzi iyona ndlela ingcono yokulala, kungekhona nje ukuba zonke izigulana zezifo ziyi-mattress engcono kakhulu, ngoko ke ibhedi yamanzi inokunyusa ixesha lokuphila. Kumandlalo wakho wamanzi ungaphila ixesha elide, ulale usempilweni ngakumbi
