Ganda rakagadzirwa sei?
Kunyatsotarisisa kuumbwa kweganda kunoratidza mitsara mitatu yakasiyana:
1. epidermis,
2. the dermis uye
3. subcutaneous layer.
Iyo dermis iri pamusoro peiyo subcutaneous layer uye inonyanya kuumbwa elastic fibres, iyo yakarukwa diagonally uye yakatwasuka, ichipa simba guru.Mitsipa yeropa inopera mudermis, nepo ziya uye sebaceous glands pamwe chete nemvere dzemvere dziripowo.
Iyo basal cell layer iri mu epidermis pakuchinja pakati payo nedermis.Iyi layer inogara ichigadzira masero matsva, ayo anobva aenda kumusoro, kupfava, ave cornified uye anozopedzisira adzimwa.
Chii chinonzi Tanning?
Vazhinji vedu tinonzwa kupiswa nezuva sechimwe chinhu chinonakidza kwazvo.Kudziya uye kuzorora kunotipa pfungwa yekugara zvakanaka.Asi chii chiri kunyatsoitika muganda?
Mwaranzi yezuva inorova melanin pigments muepidermis.Aya akasvibiswa nemwaranzi yeUVA muchiedza.Iyo melanin pigment inoumbwa nemasero akakosha akarara mukati meganda reganda anonzi melanocytes uye anobva afamba nemaseru akatenderedza kumusoro.Mavara akasvibira anotora chikamu chemwaranzi yezuva uye nokudaro anodzivirira ganda rakadzika.
Iyo UVB mhando yemwaranzi yezuva inopinda mukati meganda uye inoshanda pa melano-cytes pachayo.Izvi zvinobva zvakurudzirwa kuti zvigadzire mamwe pigment: nekudaro kugadzira hwaro hwekutsvuka kwakanaka.Panguva imwe cheteyo, mwaranzi yeUVB inoita kuti nyanga (callus) ikobvu.Iyi gobvu layer inobatsira kudzivirira ganda.
Ndezvipi zvimwe zvinokonzeresa zuva kupfuura kutsvuka?
Mhedzisiro inozorodza yekupisa kwezuva haibvi chete kubva mukudziya uye kuzorora kunowanikwa asiwo kubva kune inosimbisa mhedzisiro yechiedza chakajeka;munhu wese anoziva mafungiro akanaka anongogona kuunza zuva rezhizha rezhizha.
Uye zvakare, madiki madhisi eUVB anosimudzira meta-bolic maitiro uye anokurudzira kuumbwa kweVitamin D3.
Zuva nokudaro rinopa hupfumi hwezvakanaka zvinovaka:
1. kuwedzera kwesimba remuviri
2. kusimbiswa kwezvidziviriro zvemuviri wega
3. kuvandudzwa kwemaitiro ekuyerera kweropa
4. kunatsurudzwa h okisijeni kupihwa kunyama yemuviri
5. inobatsira mineral metabolism kuburikidza nekuvandudzwa kwe calcium
6. kudzivirira kwechirwere chemapfupa (semuenzaniso osteoporosis, osteomalacia)
Kupisa nezuva chiratidzo chechokwadi chekuti ganda rave kufumurwa zvakanyanya uye saka rinofanira kudzivirirwa chero zvipi.
Chii chinonzi chiedza chezuva?
Chiedza - uye kunyanya chiedza chezuva - itsime resimba pasina izvo hupenyu husingafungidzike.Fizikisi inotsanangura chiedza semagetsi emagetsi - semasaisai eredhiyo asi pane imwe frequency.Chiedza chezuva chinosanganisira kuwanda kwema frequency akasiyana ayo atinogona kunyatso kuona tichishandisa prism, je mavara emurarabungu.Asi iyo spectrum haigumiri patsvuku uye yebhuruu.Mushure mekutsvuka kunouya infra-red, iyo yatinoona sekudziya, mushure mebhuruu uye violet kunouya Ultra-violet, UV mwenje, izvo zvinokonzeresa kutsvuka kweganda.
Kugeza zuva kunze kana Mu solarium - pane musiyano here?
Chiedza chezuva, chingave chichibva pamadziro socket kana mudenga, chakangofanana.Hakuna chinhu chakadai se“chiedza chokugadzira” mupfungwa yokuti chakasiyana zvikuru nechiedza chezuva.Imwe mukana mukuru we sunbeds, zvisinei, ndeyekuti iyo yega zvikamu zve spectrum zvinogona kunyatsogadziriswa kune zvinodiwa nemushandisi.Pamusoro pezvo, hapana makore ekuvharisa zuva pamubhedha wezuva saka iyo dosi cam inogara yakanyatso kutsanangurwa.Izvo zvakakosha kuve nechokwadi chese kunze uye pane sunbed kuti ganda harina kuremerwa.
Kutsvuka pasina kupisa - izvo zvinoshanda sei?
Mwaranzi yezuva inogona, mukuwedzera kune yaunoda kutsvuka mhedzisiro, zvakare inokonzeresa kusada kutsvuka kweganda, erythema - mukati maro.
kuipa kwakanyanya, kupiswa nezuva.Pakutsva nezuva kamwe chete, nguva inodiwa pakutsvuka ndeyerebesa pane inodiwa pakutsvuka kweganda.
Pasinei neizvi, zvinogonekawo kuwana tan yakanaka, pasina kupisa - zvakangonaka nenzira yekugara zuva.Chikonzero cheizvi ndechekuti muviri unoderedza matanho ekutanga ekutsvuka kweganda nekukurumidza, nepo tan inogara ichizvivaka kuburikidza nekuratidzwa kakawanda.
Pamubhedha wezuva kusimba chaiko kwechiedza cheUV kunozivikanwa.Nekuda kweizvozvo chirongwa chekupisa chinogona kugadziridzwa kuti ive nechokwadi chekuti munhu anomira asati atanga kutsva uyezve kuti tan yakanaka inovakwa kuburikidza nekuratidzwa kakawanda.
