Ukuthola isikhathi sokujabulela ipaki yedolobha akuyona nje i-jaunt emnandi yesikhathi sasemini: Ucwaningo lwakamuva luphakamisa ukuthi ukuhambahamba okumnandi kungasisiza siphile isikhathi eside.
Ishicilelwe kumagazini we-Lancet Public Health, ukubuyekeza ezifundweni eziyisishiyagalolunye ze-World Health Organization (WHO), ezibandakanya abantu abangaphezu kwezigidi ezingu-8, zibheke izindawo eziluhlaza kanye nokufa okuyimbangela. Kutholakale ukuthi kunokuhlobana okukhulu phakathi kokuchayeka emapaki ezindaweni zasemadolobheni kanye nempilo engcono yomphakathi.
Abacwaningi bathola ukuthi njalo ngo-0 ukwanda endaweni eluhlaza eduze kwekhaya lomuntu, kwakukhona Ukunciphisa ngo-4% ekufeni ngaphambi kwesikhathi. Lokhu kwabonakala kuwo wonke amazwe, kuhlanganise ne-United States, iChina, iSpain, i-Australia, iCanada, i-Italy neSwitzerland.
Akungatshazwa ukuthi umyalezo walolu cwaningo uwukubalula ukuthi izindawo eziluhlaza zilungele impilo, futhi abantu abahlala ezindaweni eziluhlaza baphila isikhathi eside.
Indawo eluhlaza inganciphisa ukucindezeleka futhi ithuthukise impilo yengqondo, okungaholela ekwandeni kokusebenza ngokomzimba kanye nokuxhumana nabantu, ukunciphisa ukungcoliswa komoya, umsindo nokukhishwa kwamagesi abamba ukushisa, ukungcoliswa kwamanzi, izifo nokufa jikelele. Konke lokhu kuthuthukisa isimiso somzimba sokuzivikela ezifweni, ngakho siphinde sihumushe empilweni ende nenempilo.
Izindawo eziluhlaza, kodwa ngezinhlobonhlobo zezinto eziphilayo
Isinyathelo esilandelayo ukuphenya hlobo luni lwezikhala eziluhlaza ezivame ukusebenza kangcono. Isibonelo, abacwaningi kufanele babheke imiphumela yotshani nemigwaqo enemigqa yezihlahla uma kuqhathaniswa nezindawo ezinkulu zamapaki. Ngokuvamile abantu bathanda izindawo ezinokuhlukahluka kwemvelo nezinga elithile lokuzola, futhi ukwazi ukuchitha okungenani amahora ambalwa ngesonto endaweni enjalo kungenzeka kube nezinzuzo ezinkulu kakhulu.
Kunjalo, ukwengeza ukuvivinya umzimba kungakhuphula leyo miphumela. Isifundo, eshicilelwe ku-Journal of Applied Biomechanics, ithole ukuthi ukugibela ibhayisikili ngaphandle kubangele ukuzikhandla okucatshangwayo okuphansi ngisho nokuhamba kwe-pedaling okuhlukile.
Esinye isifundo ibonise imiphumela efanayo, ephetha ngokuthi ukuhamba ngebhayisikili ngaphandle kuvumela abagibeli bamabhayisikili ukuthi bazivocavoce ngezinga eliphezulu ngaphandle kokuzwa sengathi basebenza kanzima ukwenza kanjalo. Futhi lokho kungasebenza ngempumelelo kunoma yiluphi uhlobo lokuzivocavoca, kusukela uzizwe uxhumeke kakhulu kwimvelo ingakhuphula ugqozi, ithuthukise imizwa, futhi iguqule ngisho nezinqubo zomzimba ezihlobene nokucindezeleka. Ngokwesibonelo, ukuhamba endaweni yasehlathini kuye kwaboniswa kwehlisa umfutho wegazi, kunciphisa izinga lokushaya kwenhliziyo, kanye namazinga omfutho wegazi ophansi. i-cortisol, okuyi-hormone ehlobene kakhulu nokucindezeleka.
