Abantu bakholelwa ukuthi ukucwenga kuyilungelo lamakati (ezifuywayo nezasendle). Okwamanje, ngaphandle kwama-feline, amabhere, onogwaja, ama-tapir, ama-gorilla, ama-hyena, izingulube ze-Guinea, ama-badger, ama-raccoon, izingwejeje, ama-lemurs nezindlovu imbala zikhipha umsindo oduma ngokuzwakalayo. Futhi - kungani amakati ehlanza?
Imfihlo yokuhlanza noma lapho kuzalwa khona imisindo
Sekuyisikhathi eside izazi ze-Zoologists zifuna umthombo womsindo wesibeletho obabazekayo, ziphakamisa ukuthi kukhona uhlaka olukhethekile olubhekele ukugcotshwa. Kepha, ngemuva kokwenza uchungechunge lwezivivinyo, baqiniseka ngokungahambelani kwale mbono base bebeka enye.
Isiginali yemisipha eyenza inkontileka yezwi ivela ngqo ebuchosheni. Futhi ithuluzi elibangela ukudlidlizela okungenakulinganiswa kwezintambo zezwi ngamathambo e-hyoid atholakala phakathi kwezisekelo zolimi nogebhezi.
Ngemuva kokubuka izilo ezinomsila elabhorethri, ososayensi bezinto eziphilayo bafinyelela esiphethweni sokuthi amakati acwenga, esebenzisa ikhala lawo nomlomo, nokudlidliza kusakazeka emzimbeni wonke. Kuyathakazelisa ukuthi ngesikhathi sokuduma akunakwenzeka ukulalela inhliziyo namaphaphu wekati.
Zimbalwa izinombolo
Ukuqonda uhlobo lokuhlanjululwa, izazi zebhayoloji azizange zizibophezele ekufuneni umthombo ozwakalayo, kepha zanquma ukutadisha kabanzi imingcele yazo.
Ngo-2010, kwashicilelwa ucwaningo nguGustav Peters, Robert Ecklund no-Elisabeth Duthie, ababemele iLund University (Sweden): ababhali balinganisa ukuvama komsindo omangazayo ezindaweni ezahlukene. Kwavela ukuthi i-purr yekati ivela ku-21.98 Hz - 23.24 Hz. Ububanzi obuhlukile buyisici sokuduma kwengulule (18.32 Hz - 20.87 Hz).
Ngemuva konyaka, kwashicilelwa umsebenzi ohlangene kaRobert Ecklund noSuzanne Scholz, owawucaphuna ukubonwa kwamakati amane, ahlanze ibanga kusuka ku-20.94 Hz kuye ku-27.21 Hz.
Abaphenyi baphinde bagcizelela ukuthi ukuhlanzwa kwamakati asendle nawasekhaya kuyahlukahluka ngobude, ubukhulu nakweminye imingcele, kepha ibhendi yokuvama ihlala ingashintshi - kusuka ku-20 kuye ku-30 Hz.
Kuyathakazelisa! Ngo-2013, uGustav Peters noRobert Ecklund babheka izingulule ezintathu (ikati, ibhungu kanye nomuntu omdala) ukubona ukuthi imvamisa yomsindo ishintshile yini ngobudala. Esihlokweni esishicilelwe, ososayensi baphendule umbuzo wabo kokubi.
Izizathu zokuhlanza ikati
Zingahluka kakhulu, kepha azikaze zihlotshaniswe nolaka: ukuduma okunzima kwamakati amabili kaMashi akunakubizwa nge-purr.
Imvamisa izizathu zokuthi kungani amakati purr engamaphrosesa impela futhi agcwaliswe ngencazelo enokuthula.
Isidalwa esinoboya sidinga i-purr ukukhumbuza umnikazi ngengxenye elandelayo yokudla noma ukungabikho kwamanzi enkomishini. Kepha kaningi kunalokho, amakati akhipha ukububula kwe-languid lapho ephululwa. Kuyiqiniso, unikezwe ukungahambi kahle kwezilo ezinomsila, isikhathi lapho ungakhombisa uthando kufanele sikhethwe ngokucophelela.
Ngokusho kososayensi bezilwane, ukucwenga akukaze kube yisidina - kuhlala kuhlotshaniswa nohlobo oluthile lomzwelo we-feline, kufaka phakathi ukubonga, injabulo, ukuthula kwengqondo, ukukhathazeka noma injabulo lapho uhlangana nomnikazi.
Imvamisa inqubo yokuduma yenzeka ngesikhathi sokulungiselela ukulala: nansi indlela isilwane esifinyelela ngayo ngokushesha izinga elifunayo lokuphumula futhi silale.
Amanye amakati ahlanza ngesikhathi sokubeletha, kanti amakati asanda kuzalwa ahlanza izinsuku ezimbili ngemuva kokuzalwa.
Ukuhlanza ukwelashwa
Kukholakala ukuthi ama-felines asebenzisa i-purring ukuze alulame ekuguleni noma ekucindezelekeni: ukudlidlizela okukhipha emzimbeni kukhuthaza ukugeleza kwegazi okusebenzayo bese kuqala izinqubo zokuguqula umzimba.
Ngaphansi kwe-purr, isilwane asigcini nje ngokuthulisa, kepha futhi sifudumala uma simisiwe.
Kuphakanyisiwe ukuthi ukucwenga kubangela ukuthi ubuchopho bukhiqize i-hormone esebenza njenge-analgesic and muscle relaxant. Le hypothesis isekelwa iqiniso lokuthi ukuvuthwa kuvame ukuzwakala kusuka kumakati alimele nakumakati abuhlungu kakhulu.
Ngokusho kososayensi bezinto eziphilayo e-University of California, ukudlidliza okuvela ekususeni kuqinisa izicubu zethambo lama-feline, ahlushwa ukungasebenzi kwawo isikhathi eside: akuyona imfihlo ukuthi izilwane zingasebenzi amahora angama-18 ngosuku.
Ngokuya ngombono wabo, ososayensi beluleke odokotela abasebenza nosomkhathi ukuthi basebenzise i-25 hertz purr. Banesiqiniseko sokuthi le misindo izosheshe ijwayele ukusebenza kwamasculoskeletal kwabantu asebenesikhathi eside bengenawo amandla adonsela phansi.
Abanikazi bamafemu amancane anoboya akhiqiza i-24/7 purring (enamakhefu okulala nokudla) sekuyisikhathi eside beqiniseka ngamandla okuphulukisa amakati abo.
Ukuhlanza ikati kusindisa eblues nasekukhathazekeni, kuqeda imigraines, kulungise umfutho wegazi, kuthobe ukushaya kwenhliziyo njalo, futhi kusize ngezinye izifo.
Noma ngabe uphilile ngokuphelele, nsuku zonke uzolula isandla sakho ukuze uphathise ikati futhi uzwe ukukhononda okuthambile okuvela enhliziyweni yayo.
