Frost, nthawi zina, imatha kukhala mayeso ovuta athanzi ndikuwonetseredwa bwino osati m'njira zambiri. Nthawi zambiri timayiwala, koma ndi chisanu chachisanu chomwe chimapha tizilombo toyambitsa matenda ndi tizilombo toyambitsa matenda, potero timapereka chithandizo chachikulu kumadera a kumpoto. Chimodzi mwa mantha okhudzana ndi kutentha kwa dziko ndi chiwopsezo chomwe chingakhale chakuti kutentha sikungafike pamlingo wofunikira kupha tizilombo towopsa.
Mwachidziwitso, chisanu chimalimbikitsa kuwonda polimbikitsa kagayidwe kachakudya ka bulauni mafuta. Sizopanda pake kuti kupopera komanso kusamba m'madzi oundana kwakhala kukuchitika ku Scandinavia ndi Russia - amakhulupirira kuti njira zoterezi zimalimbikitsa chitetezo cha mthupi, magwero ena a sayansi (osati onse) amatsimikizira izi.
Komabe, palinso maphunziro ambiri omwe amawonetsa kuchuluka kwa anthu omwe amafa m'nyengo yozizira. M'nyengo yozizira, kuthamanga kwa magazi kumakwera. Malinga ndi malipoti ena, 70% ya imfa yozizira imagwirizanitsidwa ndi matenda a mtima, sitiroko ndi matenda ena a mtima. Komanso, chimfine ndi yozizira chodabwitsa, yabwino malo kufala kwa HIV ndi youma ndi ozizira mpweya. Mkhalidwewo umakulitsidwa ndi mdima, umene umakhalapo m’miyezi yachisanu. Khungu likakhala ndi kuwala kwa dzuwa, limatulutsa vitamini D, yomwe imakhala ndi thanzi labwino. Anthu akumpoto amakumana ndi kusowa kwa vitaminiyi m'nyengo yozizira, zomwe, ndithudi, sizimakhudza bwino kwambiri.
Thupi lathu limatha kusintha bwino komanso mosavutikira kuzizira, ngati sikutentha kwambiri. . Choncho, mphamvu yotetezera khungu imazindikiridwa, momwe magazi ozungulira amataya kutentha pang'ono. Kuphatikiza apo, ziwalo zofunika zimatetezedwa ku kutentha kwambiri. Koma apanso, pali ngozi: kuchepa kwa magazi ku ziwalo zozungulira za thupi - zala, zala, mphuno, makutu - zomwe zimakhala zovuta kuzizira (zimachitika pamene madzi ozungulira minofu amaundana).
Kuthamanga kwamphamvu kwa minofu kumatsogolera kutuluka kwa kutentha, komwe kumapangitsa kuti thupi lonse litenthe. Thupi limagwiritsa ntchito minofu yambiri pamene kutentha kumachepa, kotero kuti kunjenjemera kungakhale kwakukulu komanso kosasangalatsa. Mosasamala, munthu amayamba kupondaponda mapazi ake, kusuntha manja ake - kuyesa kwa thupi kuti apange kutentha, komwe nthawi zambiri kumatha kuletsa kuzizira. Kuchita masewera olimbitsa thupi kumapangitsa kuti magazi aziyenda pakhungu, motero timataya kutentha.
Zosiyanasiyana zimatengera kuzizira zimadalira momwe thupi limakhalira. Anthu aatali amakonda kuzizira mwachangu kuposa anthu amfupi chifukwa khungu lochulukirapo limatanthauza kutaya kwambiri kutentha. Mbiri ya mafuta ngati chinthu chotetezera kuzizira ndi yoyenera, koma pachifukwa ichi muyenera
M'mayiko ena, kutentha kochepa kumagwiritsidwa ntchito kwambiri pazachipatala. Thupi lonse la cryotherapy linapangidwa ku Japan pofuna kuchiza ululu ndi kutupa, kuphatikizapo rheumatic ndi zina. Odwala amatha mphindi 1-3 m'chipinda chokhala ndi kutentha kwa -74C. Zaka zingapo zapitazo, ofufuza a ku Finnish anafotokoza zotsatira za kafukufuku wopangidwa pakati pa amayi a 10. Kwa miyezi ya 3, ophunzirawo adamizidwa m'madzi oundana kwa masekondi a 20, ndipo adachitanso magawo a thupi lonse a cryotherapy. Kuyeza magazi kunakhalabe kosasinthika kupatula mlingo wa norepinephrine patangopita mphindi zochepa mutatha kumizidwa m'madzi oundana. Zotsatira zake zimakhala chifukwa chakuti zimatha kuyambitsa kudzidalira, komanso kukonzekera kuchita zinthu zina. Norepinephrine imasokoneza mahomoni odziwika bwino a mantha, adrenaline. Zofunikira za thupi zimakhazikika pambuyo pa kupsinjika, zochitika za tsiku ndi tsiku ndi zovuta zosiyanasiyana ndizosavuta kuthetsa.
