Maererano nemigumisiro yezvidzidzo zvakaitwa munyika dzakasiyana-siyana, zvakawanikwa kuti kuwanda kwemuviri wevana vakaberekwa nevakadzi vanosvuta pavanenge vachiita pamuviri vashoma pamusana pevhisi 160 - 230 g kupfuura uremu hwemwana wevana vanaamai vasina kusvuta. Yakawanikwawo kuti vakadzi vanosvuta pavanenge vachiita pamuviri vanoberekwa vasati vasvika nguva mbiri kana katatu kakawanda. Yakafanirwawo kuti mwana wechina wega akaberekwa akafa angave akapona dai vabereki vavo vakanga vasina kusvuta uye vaiziva nezvekukuvadza kwefodya nedoro nekuda kwehutano hwevana.
Muvana vaduku vari muimba yekuputa, kurara kunokanganiswa, chido chinoderera, kazhinji kune chirwere chemukati. Mukukura kwepfungwa uye mumuviri, vana vanotanga kusvetuka shure kwevezera ravo. Vechiduku vakatanga kusvuta vanove vane chirwere, vanogumbuka, kufambira mberi kuchikoro kunoderera, vanorwara kakawanda, vanopera shure mumitambo. Zvakaratidzwa kuti kana tikabvuma simba rebasa revana vechikoro iro muviri wavo hauna kutungamirirwa nefodya, inotora imwe zana, zvino inotarisira nhamba shomanana yevasvuta pa makumi mapfumbamwe nemaviri, asi vazhinji vanoputa vanosvika kusvika makumi manomwe nemanomwe. Zvinonyanya kukoshesa kudzokorora pakati pevana vanosvuta. Kazhinji, vana vanopisa nokukurumidza, pachivande, pazvinenge zvichizivikanwa kuti nekutsva nekukurumidza kwefodya kusvika mumusvi inopfurikidza kazhinji nicotine, zvakasiyana nezvishoma zvinopisa. Saizvozvowo, zvinokuvadza kubva kusvuta zvinowedzera kuwedzera. Vechidiki vakawanda vanowanzoputa fodya, asi chaizvoizvo vanopedza fodya kusvika kumugumo, kureva kuti, chikamu chefodya ine yakawanda chezvinhu zvinotyisa inoshandiswa. Kana uchitenga fodya, vana vanopedza imwe yemari yavanopa kunze kwemasikati, uye sechikonzero musadya. Kazhinji unogona kuona kuti varume vacho vanosvuta sei kambani huru ine cigareti imwechete, ichiipfuura kubva kune imwe kuenda kune imwe. Nenzira iyi yekusvuta, mungozi yekuendesa zvirwere zvinotapukira zvinowedzera. Kuunganidza fodya kubva pasi kana kukumbira kune vanhu vakuru kune ngozi.
Izvi zvinokoshawo kuti titaure nezvekukuvadza doro uye kuti inobata sei muviri usina kuchena wevana nevechiri kuyaruka. Kwemakore anenge makumi mana, masayendisiti pasi rose ave achinyanya kunetseka pamusoro pezvipingamupinyi zvinotarisana nezera duku - vechiduku, vaduku uye vana. Iyo mubvunzo wekuwedzera kuri kuwedzerwa kunwa doro nevana. Somuenzaniso, muUnited States of America, 91% yevana vane makore 16 vekuchikoro vanodya doro. MuKanada, vanenge 90% vevadzidzi mumakoroji 7-9 vanodya doro. MuFederal Republic of Germany, imwe yezana yevana vane makore 8-10 vakasungwa nemapurisa munharaunda yekudhakwa.
Zvichida, usava nemafungiro chaiwo, kuitira kufungidzira kukanganisa kunogona kukonzera musikana kunyange kushandiswa kumwe kwewaini kana kunyange waini. Kutsvakurudza kwemazuva ano kunoratidza kuti hakuna maviri uye nhengo mumutumbi wemuviri usingabatsiri nedoro. Kana inopisa, inononoka kuputika muropa. 10% chete yehuwandu hwezvinodhaka zvinodyiwa zvakadhindwa zvisingachinji kubva mumuviri. Iyo yakasara yakawanda yedoro inotenderera mumuviri wose neropa, kusvikira yose yakakamurwa. Mukuona kwekukwirira kwepamusoro kwe "madiki" matukisi, kusvibiswa kwavo nemvura kunoita kuti zvive nyore kuti doro ripararire nokukurumidza mumuviri wose.
Zvinokonzera dambudziko rezvinwiwa zvinodhaka zvinonyanya kukanganisa basa rehurongwa hwemagetsi. Kana iwe ukatora ropa rehutori hwehutachiwana hwega, ipapo muuropi huchava 1.75, uye muropa - 1.45. Kunyangwe doro duku doro rinokanganisa kushandiswa kwemishonga yehutachiona, kutapurirwa kwemaitiro emagetsi. Panguva imwecheteyo, basa remakemikari epfungwa rinowedzera: kune kuwedzerwa kwekusimudzira, kuwedzera, uropi hwekushaya ropa. Pazera remakore, hutachiona hunenge huchizadzwa ne phosphorus uye huchiri mumvura, huri mudenga rekugadzirisa kwehutano uye hwemagariro, saka doro rinokuvadza zvikuru. Kunyangwe kunwa kumwe kunogona kuva nemigumisiro yakaipa kwazvo.
Kakawanda kana kudzokorora kushandiswa doro kunoparadza zvakanyanya pamweya wechidiki. Panguva imwecheteyo, kwete chete kukurudzirwa kwemafudzi akakwirira ekufunga kwakadziviswa, kukudziridza kwetsika uye tsika dzakanaka uye mazano ekufungidzira, asi unyanzvi hwakatove huchashanduka hunofa.
Izvo "chinangwa" chinotevera chiropa. Icho chiri munhengo iyi kuti kuparadzaniswa kwayo kunoitika pasi pekuita kwe enzymes. Kana chiyero chewaini chinokonzerwa nechiropa chiri chakakwirira kudarika kuora kwehuwandu, ipapo kunwa doro kunowanzoitika, izvo zvinokonzera kukuvadzwa kwemasero emuropa. Chimiro chemasero echiropa chinopwanyika, zvichiita kuti chigunwe chechivi chiwedzere. Nekushandisa kwakanyatsodha doro, mafuta anoshandiswa mumasero emuropa anokonzera necrosis yezvigunwe zveropa - zvichiita kuti chirwere chetrhosis chinogara chichienda nechisimba chinodhaka. Pamuviri wevechiri kuyaruka, doro rine zvinotonyanya kuiparadza, sezvo chiropa chiri muzhe yegadziriro uye inoshanda. Maitiro eropa anokonzera kukanganisa khabhoni neprotein metabolism, iyo yakakura ye enzyme uye mavitamini. Doro, iwe unogona kuti, "inopisa" mucous membrane yemudumbu, sophagus, inokanganisa secretion uye yakagadzirwa gastric juice. Izvi zvinowedzera kushandiswa kwekudya, iyo pakuguma kunogumbura zvakanyanya kukura nekukura kwevechiri kuyaruka.
Nokudaro, doro rinokanganisa muviri, rinodzivisa kusanganiswa uye kuumbwa kwehurongwa uye nhengo dzaro, uye mune dzimwe nguva, somuenzaniso, kana zvichishandiswa zvisina kunaka, zvinomisa zvachose kukurudzirwa kwezvimwe zvinhu zvehutano hwepamusoro hwehutano. Zviduku zvezera remhuka, iyo inowedzera doro inoshandiswa pairi. Mukuwedzera, kushandisa doro nevechiri kuyaruka kunotungamirira pakuumbwa kwechidhakwa nekukurumidza zvakanyanya kudarika vakuru.
Iye zvino unoziva nezvekukuvadza kwefodya uye doro nekuda kwehutano hwevana, saka iwe unenge uchiteerera zvakanyanya kuita zvinokuvaraidza uye mararamiro evana vako nevanasikana vako.
