Ubukho boburharha ebomini bethu abuncedisi ngokuchasene noxinzelelo noxinzelelo Uphando lubonakalisile ukuba ukuhleka kunokubandisa ubomi babantu. Oku kulandelayo zizizathu ezine ezinxulumene nezempilo zokuba kutheni usitya ukuhleka rhoqo.
Ukuhleka kuthintela izifo. Xa sihleka, siphefumla nge-diaphragm, eyonyusa ukuhamba okudlula kwii-lymph node. Oku kunceda ukuphelisa ityhefu kwaye kusikhusela kwizifo ngokwandisa inani lee-lymphocyte ezisegazini.
Isifundo esivela kwii-80s sabonisa ukuba amanqanaba ehomoni ekhuthaza amajoni omzimba anyuke xa abathathi-nxaxheba bebukele iividiyo ezihlekisayo.
Ukuhleka kunciphisa uxinzelelo. Amanqanaba eehomoni ezintathu ahambelana noxinzelelo (i-cortisol, i-epinephrine kunye ne-DOPAC) ancitshisiwe xa sihleka. Oku kungenxa yokusebenza kwenkqubo ye-parasympathetic nervous system, ethomalalisa umzimba uphela kwaye ikhuphe ii-enfdorphins ezichasene noxinzelelo.
Ukuhleka kukhusela intliziyo. Olunye uphononongo lufumanise ukuba abantu abanesifo sentliziyo bebengaphantsi ngamashumi amane eepesenti ukuba bahleke kwiimeko ezininzi xa kuthelekiswa nabantu abasempilweni abakwiminyaka efanayo. Isizathu iya kuba kukuba uxinzelelo lwengqondo luyehla i-endothelium, isithintelo sokukhusela esigcina imithambo yegazi. Oku kunokubangela uthotho lweempendulo zokudumba ezikhokelela ekufumaneni amafutha kunye ne-cholesterol kwimithambo yegazi, kwaye ekugqibeleni ibe sisifo sentliziyo.
Ukuhleka kukwalawula uxinzelelo lwegazi kwaye kunyuse ukuhamba kwegazi emzimbeni wonke, zombini ezingundoqo kwimpilo yentliziyo.
Ukuhleka kutshisa iikhalori. Kuba isebenzisa amandla kwaye inyusa izinga lokubetha kwentliziyo yakho nge-10 ukuya kuma-20 epesenti, ukuhleka imizuzu eli-10-15 ngemini kunokutshisa iikhalori ezili-10 ukuya kwezingama-40 ngosuku, ezinokuba malunga neekhilogremu ezi-2 ngaphantsi konyaka.
