Sleeping ohlangothini kuhle ubuchopho

Akukhona izindaba isimo lapho umuntu elele, kungathinta indlela yekuma bese ukugaya, kodwa kuvela ukuthi umthelela omkhulu zengqondo kwempilo yengqondo. Ucwaningo lwamuva luye lwabonisa uxhumo lwayo ikhono zobuchopho ukuze bafeze umzimba esifanele, okuhlanganisa ukususwa ngendwangu amakhemikhali ayingozi. Ngakho, kukhona ukuma ingalali nokuncane oluncamelayo.

Kungani kungcono ukulala ohlangothini lwakhe?

Ososayensi bathole ukuthi elele ngohlangothi lwakho kunokuba emhlane wakho noma esiswini. Lesi sikhundla lwezendawo evumela umzimba ukuze uthole kahle kakhulu balahle imfucuza ubuchopho zamakhemikhali. Zakhamizi University of Rochester (New York) Maiken Nedergard, owachitha eziningi izifundo, uphawula iqiniso ezithakazelisayo: abakulesi simo ngokuvamile ozitika embhedeni eziningi zezilwane, kuhlanganise izakhamuzi izilwane zasendle, futhi abantu bathanda ukuba baphumule ingxenye enkulu yalo ukuma ethile . Usosayensi ukholelwa ukuthi kulesi simo ubuchopho kakhulu ngempumelelo ohlanziwe imfucuza umzimba zanqwabelana ngesikhathi sihlale siphapheme.

Ekuhloleni kwabo, abacwaningi wasebenzisa indlela ashukumisayo kuhlukanisa i-magnetic resonance imaging (MRI), esangenza umbono kangcono izinguquko kwamakhemikhali izakhiwo yangaphakathi kwezicubu ezihlukahlukene ubuchopho, ngokukhethekile, okubizwa ngokuthi glimfatichesky endleleni (uhlelo lapho utshwala lemifanekiso, ie, i-cerebrospinal fluid futhi kushintshwa uketshezi interstitial ezizungezile wonke amanye emangqamuzaneni omzimba). Lokhu umsebenzi ebalulekile bokuphila ivumela ukuqeda imfucuza namanye amakhemikhali buthelela asebuchosheni zisuswe (isib beta-amyloid futhi tau amaprotheni). overabundance yabo kungabangela Alzheimer futhi Parkinson.

Njengoba ucwaningo kanye zokwelapha, inqubo ekususeni beta-amyloid icushiwe ngesikhathi sokulala. Kodwa akugcini lapho. On wokuhlanza umfutho kuthinta ukuma lapho umuntu noma isilwane olalayo.

Ingqikithi ukuhlola

I ucwaningo zazenziwa ku abadala amagundane laboratory egxilile ubuthongo yokufakelwa (izinzwa) kanye loan embondelene in omunye izikhundla ezintathu (ohlangothini, ku esiswini noma emuva). Khona-ke, lolu cwaningo wadalula glimfatichesky indlela ubuchopho kwezilwane elele.

Njengoba sekuchaziwe nguDkt Helene Benveniste, co-umbhali cwaningo, ogama Imiphumela yashicilelwa "Neyrosayns" umagazini, ukuhlaziya wabonisa ukuthi umzimba kwaphumelela kakhulu lapho umuntu ephelelwa ubuthongo nasemkhakheni isikhundla lateral. Njengoba esho, le miphumela ngombandela zisebenze kubantu. Pose ukulala ohlangothini kusobala kunenzuzo ezingaphezu kuka imigomo ngemuva noma isisu.

Kungakhathaliseki lokhu kuyiqiniso ngokuphathelene abantu?

Isibonelo "abafowethu ezincane" ibonisa ukuthi izilwane ezincelisayo (izinja, amakati, ngisho nezindlovu) uthanda ukulala ngaleyo ndlela, nakuba ababhali ayikwazanga abehluleka ukuyinaka ukuthi ukuziphatha ejwayelekile isilwane sasendle is bakha ngaphansi kwethonya kwezimo okusinda, futhi ngenxa yalokho zingase zihluke kusuka umuntu. Lolu cwaningo lwenziwe emagundaneni hhayi ngokugcwele okwamanje enikeza izizathu ukuze uthumele imiphumela abantu, nakuba akuyona umqondo omuhle kakhulu.

Izinhlobo eziningi zama-komqondo ezihlobene nokusebenzelana ubuthongo neziyaluyalu, kuhlanganise nobunzima ngilale. Ucwaningo luthole ubufakazi ezikhulayo ukuthi lezi zinkinga kungase ukusheshisa ukukhohlwa e-Alzheimer. "Okutholakele zethu zikunikeza umbono omusha ngalolu daba, okubonisa ukubaluleka ukuma ngesikhathi sokulala," - wathi ekuphetheni Nedergard.
