Kurapa Kwakareruka
Inogona kushandiswa chero nguva, kusanganisira husiku.
Inogona kushandiswa mumba, muchivande.
Mari yekutanga uye mari yemagetsi
Chiedza chine hutano
Kusimba kunogona kusiyana
Hapana chiedza cheUV chinokuvadza
Hapana vhitamini D
Zvinogona kuvandudza kugadzirwa kwesimba
Inoderedza marwadzo zvakanyanya
Hazvina kusvibisa zuva
CHIEDZA CHEZUVA CHECHISIKO
Hazviwanikwe nguva dzose (mamiriro ekunze, husiku, nezvimwewo)
Inowanikwa kunze chete
Zvechisikigo, hapana muripo
Chiedza chine hutano uye chisina hutano
Kusimba hakugone kuchinjwa
Mwenje weUV unogona kukonzera kukuvara kweganda nezvimwewo
Inobatsira kugadzirwa kwevhitamini D
Inoderedza marwadzo zvine mwero
Zvinoita kuti zuva ritsvuke
Kurapa nechiedza chitsvuku chishandiso chine simba uye chinoshanda zvakasiyana-siyana, asi zviri nani pane kungobuda kunze muzuva here?
Kana uchigara munzvimbo ine makore, kuchamhembe usina mukana wekuona zuva nguva dzose, saka kurapwa nechiedza chitsvuku hakusi nyore - kurapwa nechiedza chitsvuku kunogona kutsiva chiedza chepanyama chidiki chiripo. Kune avo vanogara munzvimbo dzinopisa kana dzimwe nzvimbo dzine mukana wekuwana chiedza chezuva chakasimba zuva nezuva, mhinduro yacho yakaoma zvikuru.
Misiyano mikuru pakati pezuva nechiedza chitsvuku
Chiedza chezuva chine chiedza chakasiyana-siyana, kubva kuchiedza che ultraviolet kusvika kune near-infrared.
Mukati mechiedza chezuva mune mawavelengths ane hutano ered ne infrared (anowedzera kugadzirwa kwesimba) pamwe ne UVb light (inokurudzira kugadzirwa kwevhitamini D). Zvisinei kune mawavelengths ari mukati mezuva anokuvadza zvakanyanya, akadai sebhuruu ne violet (anoderedza kugadzirwa kwesimba uye anokuvadza maziso) uye UVa (inokonzera kupiswa nezuva/kupiswa nezuva uye kupiswa ne photoaging/kenza). Iyi wide spectrum inogona kudiwa pakukura kwezvirimwa, photosynthesis uye mhedzisiro dzakasiyana pa pigments mumarudzi akasiyana, asi hazvisi zvese zvinobatsira vanhu nemhuka dzakawanda. Ichi ndicho chikonzero nei sunblock uye SPF sunscreens zvichidikanwa muzuva rakasimba.
Mwenje mutsvuku imhando yakamanikana, yakaparadzana, inotangira pa600-700nm - chikamu chidiki chezuva. Infrared inoshanda mumuviri inotangira pa700-1000nm. Saka marefu echiedza anokurudzira kugadzirwa kwesimba ari pakati pe600 ne1000nm. Marefu aya echiedza chetsvuku neinfrared ane mhedzisiro inobatsira chete pasina migumisiro inozivikanwa kana zvinhu zvinokuvadza - zvichiita kuti kurapwa nechiedza chetsvuku kuve rudzi rwekurapa rusina kunetseka kana tichienzanisa nekuratidzwa kwezuva. Hapana makirimu eSPF kana mbatya dzekudzivirira zvinodiwa.
Pfupiso
Chinhu chakanaka ndechekuti munhu awane chiedza chezuva uye nzira yekurapa nechiedza chitsvuku. Kana zvichibvira, tsvaga chiedza chitsvuku mushure mekushandisa chiedza chitsvuku.
Mwenje mutsvuku uri kudzidzwa maererano nekupiswa nezuva uye kukurumidzisa kuporeswa kwekukuvara kwemwaranzi yeUV. Zvichireva kuti chiedza mutsvuku chine simba rekudzivirira pakukuvadzwa kunogona kuitwa nechiedza chezuva. Zvisinei, chiedza mutsvuku chega hachikurudzire kugadzirwa kwevhitamini D muganda, izvo zvaunoda kuti chiedza chezuva chiite.
Kuwana ganda rakanyatsojeka pachiedza chezuva kuti rigadzirwe vhitamini D, pamwe chete nekurapa nechiedza chitsvuku pazuva rimwe chete kuti rigadzirwe simba remasero pamwe ndiyo nzira inonyanya kudzivirira.
