Kwiminyaka yakutshanje, iibhafu zamanzi abandayo—ngamanye amaxesha ezibizwa ngokuba zii-cold plunges okanye ii-ice baths—zisuke kwindawo yabadlali ababalaseleyo zaya kwizenzo zempilo eziqhelekileyo. Ubungqina obukhulayo besayensi obuvela kwizifundo zasekhaya nezamazwe ngamazwe bubonisa ukuba ukuchayeka rhoqo emanzini abandayo kunokudlala indima ekuqiniseni ukusebenza komzimba kunye nokuphucula ukuqina komzimba ngokubanzi.
Impendulo yomzimba iqala ngokulawula ubushushu. Xa umzimba ungena emanzini abandayo ngequbuliso, imithambo yegazi iyancipha kwaye ukujikeleza kwegazi kuya kutshintshwa okwethutyana ukuze kukhuselwe amalungu abalulekileyo. Xa uphuma kwindawo ebandayo, imithambo yegazi iyavuleka, ivuselela ukuhamba kwegazi kwaye ikhuthaze ukubuyela esiqhelweni. Uphando lubonisa ukuba le nkqubo inokuvuselela ukuveliswa kweeseli ezithile zomzimba, ezifana nee-lymphocytes kunye neeseli zokubulala zendalo, ezibalulekileyo ekukhuseleni kwiintsholongwane.
Ukongeza, ukuntywiliselwa emanzini abandayo kukholelwa ukuba kuvuselela inkqubo yemithambo-luvo ezimeleyo, okunyusa amanqanaba e-norepinephrine—ihomoni enxulunyaniswa nokuphaphama kunye nemiphumo yokulwa nokudumba. Izifundo ezenziwe eYurophu zibonise ukuba abantu abaziqhelisela ukuhlamba ngamanzi abandayo rhoqo banokufumana usulelo oluncinci lwendlela yokuphefumla ephezulu xa kuthelekiswa nabo bangenzi njalo. Nangona iziphumo zahlukile kwaye kufuneka uphando olukhulu, le ndlela ibonisa ukuba kunokwenzeka ukuba umzimba uqine.
Ngokwembono ebanzi, ukubanda kunokunceda umzimba ukuba uqhelane noxinzelelo ngokufanelekileyo. Ngokufaka umngeni kwinkqubo yokulawula ubushushu, abantu bakha ukunyamezela kancinci kancinci, okunokuguqulela ekulawuleni uxinzelelo oluphucukileyo kubomi bemihla ngemihla. Olu hlengahlengiso oluguquguqukayo luthathwa njengoncedo oluxabisekileyo kwiindlela zemveli zokugcina impilo, ezifana nokutya okunesondlo kunye nokuzilolonga rhoqo.
Nangona kunjalo, kubalulekile ukusondela ekuhlambeni ngamanzi abandayo ngendlela efanelekileyo. Ukuntywiliselwa ngequbuliso okanye ixesha elide kunokuba yingozi, ingakumbi kubantu abaneengxaki zentliziyo. Iingcali zicebisa ukuba uqale ngexesha elifutshane—ngokufuthi ngaphantsi kwemizuzu emibini—kwaye kancinci kancinci ukukhulisa ukubonakaliswa njengoko ukunyamezelana kuqhubeka. Ingcebiso yobungcali iyacetyiswa kwabaqalayo.
Ukuqukumbela, iibhafu zamanzi abandayo ziyindlela ethembisayo nefikelelekayo yokuphucula ukusebenza komzimba kunye nokuqina. Ngokukhuthaza ukulawulwa kobushushu, ukuxhasa umsebenzi womzimba, kunye nokukhuthaza ukuziqhelanisa noxinzelelo, zibonelela ngokongeza ngokupheleleyo kwiinkqubo zempilo zanamhlanje. Nangona zingathathi indawo yonyango okanye iindlela zokuphila ezisempilweni, zingasebenza njengesixhobo esibalulekileyo ekufuneni impilo eqinileyo kunye nokumelana nezifo.
