Abantu, njengazo zonke izilwane ezincelisayo, siyakwazi ukulawula ukushisa komzimba ngenxa ye-hypothalamus, okuyingxenye yobuchopho etholakala ebuchosheni esebenza ngendlela efanayo ne-thermostat: lapho izinga lokushisa lendlu liphakeme kunephuzu elibekiwe, limisa ukushisa ukuze kwehle.
La ukuzwa okushisayo Kungukuzwa kwamakhaza noma ukushisa esikuzwayo ngokuya ngenhlanganisela yemingcele yezulu, phakathi kwayo okukhona umswakama nomoya. Kepha, Ibalwa kanjani?
Ngeke sibe nokushisa okufanayo ngosuku lapho i-thermometer ifunda u-35ºC kanye nomoya waseningizimu ovunguza ngamakhilomitha angama-20 ngehora, kunangalolo olunye usuku olunezinga lokushisa elifanayo kodwa kungabikho moya. Kungani? Ngoba nxazonke zomzimba ungqimba lomoya lugxilile, olubizwa ngokuthi ungqimba lwemingcele. Ukuzaca kungenxa yomphumela womoya, kukhulu ukulahleka kokushisa.
Abantu banokushisa komzimba okungu-37 degrees Celsius. Kodwa-ke, ngokusho kwe- izifundo ezahlukahlukene singathwala ama-degree angama-55 nomswakama ojwayelekile, noma amazinga aphezulu ezimweni zomswakama ophansi. Isibonelo ama-sauna, lapho izinga lokushisa lifinyelela kuma-degree ayi-100 futhi abantu abaya lapho baphuma ngezinyawo zabo ngemuva kweseshini 😉.
Kulungile manje uma umswakama uphakeme noma uphakeme kakhulu lapho-ke sizoba nezinkinga. Ngomswakama ongu-100% besizobekezelela ama-degree angama-45 kuphela imizuzu embalwa, njengoba umhwamuko wamanzi ungagodola emaphashini.
Ulinganiswa kanjani umoya opholile? Ngo-2001 ososayensi baseCanada nabase-United States basungula ifomula eqondile abayithola ngokusebenzisa izivivinyo zaselabhoratri besebenzisa izindiza zomoya emazingeni okushisa ahlukahlukene nangamandla omoya ebusweni nokubheka ukulahleka kokushisa isikhumba sabo esikutholile. Ingabe okulandelayo:
I-Tst = 13.112 + 0.6215 Ta -11.37 V0.16 + 0.3965 Ta V0.16
Ngakho-ke singathola ukuthi ngokushisa okungu-10ºC nomoya ka-50km / h, umuzwa oshisayo ongaba yi--2ºC. Ngakho-ke kuthakazelisa kakhulu ukunaka umzimba wethu ngaphambi kwe-thermometer ukwazi ukuthi yiziphi izingubo okufanele sizigqoke.
