Isonto elilodwa nje kuphela lokulala ngokwanele kuphazamisa imetabolism ye-cholesterol iye ezingeni lofuzo, okungaholela ekwakhekeni kwe-atherosclerosis, isifo esibi semithambo. Lokhu kufakazelwa yimiphumela yocwaningo olushicilelwe ku- Imibiko yeSayensi, kubhala ingosi ethi "Neurotechnology.rf".
Njengoba sonke sazi kahle, izinto eziningana zokuphila zingaholela ekwehlulekeni komzimba lapho i-plaque iqala ukwakheka ezindongeni zangaphakathi zemithambo yegazi, ivimbe ukugeleza kwegazi, kwandise ingozi yokuhlaselwa yisifo senhliziyo nokushaywa unhlangothi. Ama-plaque akhiwa yi-low density lipoproteins (LDL) - cholesterol "embi".
Ababhali bocwaningo baphakamise ukuthi ukuncishwa ubuthongo kwakuhlobene kakhulu nokwakhiwa koqwembe emithanjeni yegazi, futhi bafunda kahle ukuthi kwenzeka kanjani. Ososayensi benze ukuhlolwa kwabo futhi bacubungula amasethi edatha asuka kokunye ukuhlolwa okubili ngokuhlangana nakho. Ababambe iqhaza kowokuqala baphucwa ubuthongo obujwayelekile isonto lonke endaweni elawulwa elebhu ngokubambisana neFinnish Institute for Occupational Health. Idathasethi yesibili neyesithathu zivela ocwaningweni lwe-DILGOM (indlela odla ngayo, indlela ophila ngayo, izici zofuzo zokukhuluphala kanye ne-metabolic syndrome), kanye nokutadisha ubungozi benhliziyo nemithambo yegazi kuFinns osemncane (Ubungozi Benhliziyo Nemithambo Yesifundo ku-Young Finns Study).
Ngemuva kokuhlaziya le datha, abacwaningi baphetha ngokuthi izakhi zofuzo ezithintekayo ekulawuleni ukuthuthwa kwe-cholesterol bezingabonakali kakhulu kubantu abantula ubuthongo kunalabo abalala ngokwanele. Ngaphezu kwalokho, bathole ukuthi abantu abangalali ngokwanele banamazinga aphansi e-high-density lipoprotein HDL (cholesterol "enhle"). Ngakho-ke, ukuncishwa ubuthongo kwehlisa kakhulu amazinga e-HDL, nawo akhuthaze ukwakheka kwamapulangwe ngaphakathi kwemithambo yegazi nezinkinga zenhliziyo ezingaba khona.
“Kuyathakazelisa kakhulu ukuthi zonke lezi zinto ezinomthelela ekuqhubekeni kwesifo sokuqina kwemithambo yegazi - ukusabela kokuvuvukala kanye nezinguquko ku-cholesterol metabolism - zitholakala zombili ngokuhlolwa kanye nakwimininingwane yedatha. Ucwaningo lokuhlola luye lwabonisa ukuthi isonto elilodwa nje kuphela lokulala ngokwanele liqala ukuguqula ukuqina kokuphendula komzimba nokuqina komzimba. Inhloso yethu elandelayo ukuthola ukuthi yikuphi ukungalali kahle okudala lezi zinqubo, ”kusho uVilma Aho, ongomunye wababhali besifundo.
Ucwaningo eminyakeni yamuva luxhumanise ukulala okunganele nezifo eziningi ezingalapheki, kufaka phakathi ukukhuluphala, isifo sikashukela, ukuphazamiseka kwengqondo nokukhubazeka kwememori. Iphinde ihlotshaniswe nesifo i-Alzheimer's, lonke uhla lwezifo zenhliziyo, futhi iba nomthelela omubi ezinhlakeni zomzwelo zomuntu. Funda lawa macebiso avela ku-Arianna Huffington, ummeli wobuthongo obusezingeni, wokuthi ungalala kanjani futhi ulale ngokwanele.
