Into eyodwa eyenza ubusika bungakhululeki kubantu, ngisho nangaphakathi kwesakhiwo esihle esifudumele, umswakama ophansi.Abantu badinga izinga elithile lokuswakama ukuze bakhululeke.Ebusika, umswakama ongaphakathi endlini ungaba phansi kakhulu futhi ukuntuleka komswakama kungamisa isikhumba sakho nolwelwesi lwamafinyila.Umswakama ophansi futhi wenza umoya uzizwe ubanda kunalokho oyikho.Umoya owomile ungomisa izinkuni ezindongeni naphansi kwezindlu zethu.Njengoba ukhuni olomile luncipha, lungabangela ukuqhekeka phansi kanye nokuqhekeka kodonga olumisiwe nokhonkolo.
Umswakama olinganiselwe womoya uthinta indlela esizizwa sikhululeke ngayo.Kodwa yini umswakama, futhi yini "umswakama ohlobene" ohlobene nayo?
Umswakama uchazwa njengenani lomswakama emoyeni.Uma umile endlini yokugezela ngemva kokugeza okushisayo futhi ubona isitimu silenga emoyeni, noma uma ungaphandle ngemva kwemvula enkulu, khona-ke usendaweni enomswakama ophezulu.Uma umi phakathi nogwadule ongazange uyibone imvula izinyanga ezimbili, noma uma uphefumula umoya ethangini le-SCUBA, kusho ukuthi ubhekene nomswakama ophansi.
Umoya uqukethe inani elithile lomhwamuko wamanzi.Isilinganiso somhwamuko wamanzi noma isiphi inqwaba yomoya esingaba nawo sincike ekushiseni kwalowo moya: Lapho ushisa bhe, kulapho ongawabamba khona amanzi amaningi.Umswakama ophansi ohlobene usho ukuthi umoya womile futhi ungabamba umswakama omningi kulelo zinga lokushisa.
Isibonelo, ku-20 degrees C (68 degrees F), i-cubic meter yomoya ingabamba umkhawulo wamagremu angu-18 amanzi.Ku-25 degrees C (77 degrees F), ingabamba amagremu angu-22 amanzi.Uma izinga lokushisa lingu-25 degrees C kanye ne-cubic meter yomoya iqukethe amagremu angu-22 amanzi, khona-ke umswakama ohlobene ungamaphesenti angu-100.Uma iqukethe amagremu angu-11 amanzi, umswakama ohlobene ungamaphesenti angu-50.Uma iqukethe amagremu ayiziro wamanzi, umswakama ohlobene ungamaphesenti aziro.
Umswakama ohlobene udlala indima enkulu ekunqumeni izinga lokunethezeka kwethu.Uma umswakama ohlobene ungamaphesenti angu-100, kusho ukuthi amanzi ngeke ahwamuke -- umoya usuvele ugcwele umswakama.Imizimba yethu incike ekuhwamukeni komswakamo esikhunjeni sethu ukuze zipholise.Lapho umswakama uphansi, kuba lula ukuthi umswakama uhwamuke esikhumbeni sethu kanye nokubanda esikuzwayo.
Kungenzeka ukuthi uzwile ngenkomba yokushisa.Ishadi elingezansi libonisa ukuthi izinga lokushisa elithile lizozizwa lishisa kangakanani kithi kumaleveli omswakamo ahlukahlukene.
Uma umswakama olinganiselwe ungamaphesenti angu-100, sizizwa sishisa kakhulu kunalokho okushiwo izinga lokushisa langempela ngoba umjuluko wethu awuhwamuki nhlobo.Uma umswakama ohlobene uphansi, sizizwa sipholile kunezinga lokushisa langempela ngoba umjuluko wethu uhwamuka kalula;futhi singazizwa somile ngokwedlulele.
Umswakama ophansi unemiphumela okungenani emithathu kubantu:
Yomisa isikhumba sakho nolwelwesi lwamafinyila.Uma ikhaya lakho linomswakama ophansi, uzoqaphela izinto ezifana nezindebe eziqhekekile, isikhumba esomile nesilumayo, nomphimbo owomile lapho uvuka ekuseni.(Umswakama ophansi nawo womisa izitshalo nefenisha.)
Kwenyusa ugesi omile, futhi abantu abaningi abathandi ukuchazelwa njalo uma bethinta into eyinsimbi.
Kwenza kubonakale kubanda kunalokho okuyikho.Ehlobo, umswakama ophezulu wenza kubonakale kufudumele kunalokho oyikho ngoba umjuluko awukwazi ukuhwamuka emzimbeni wakho.Ebusika, umswakama ophansi unomphumela ophambene.Uma ubheka ishadi elingenhla, uzobona ukuthi uma kungu-70 degrees F (21 degrees C) ngaphakathi kwekhaya lakho futhi umswakama ungamaphesenti angu-10, uzwa sengathi ungu-65 degrees F (18 degrees C).Ngokumane ulethe umswakama ufike kumaphesenti angu-70, ungenza izwe lifudumale ngo-5 degrees F (3 degrees C) ekhaya lakho.
Njengoba kubiza kancane kakhulu ukunyakazisa umoya kunokuwufudumeza, isihwamisi singakongela imali eningi!
Ukuze uthole ukunethezeka kwangaphakathi nempilo engcono kakhulu, umswakama ohlobene wamaphesenti angaba ngu-45 ufanelekile.Emazingeni okushisa avame ukutholakala endlini, leli zinga lomswakamo lenza umoya uzwe cishe lokho okushiwo izinga lokushisa, futhi isikhumba sakho namaphaphu akomi futhi acasuke.
Izakhiwo eziningi azikwazi ukugcina leli zinga lomswakama ngaphandle kosizo.Ebusika, umswakama ohlobene uvame ukuba ngaphansi kakhulu kunamaphesenti angu-45, futhi ehlobo ngezinye izikhathi uphakeme.Ake sibone ukuthi kungani lokhu.
