Ehe, mibhedha yekutsvukisa ganda inoshandisa chiedza cheUV (ultraviolet), kunyanya UVA neUVB rays, kukurudzira kugadzirwa kwemelanin muganda uye kuriita kuti ritsvukise ganda. Hezvino zvaunofanira kuziva:
Mhando dzemwenje weUV mumibhedha yekupisa
Mwaranzi yeUVA (95–99% yezvinobuda):
Chinangwa: Zvinopinda mukati meganda, zvichikonzera kusviba kweganda nekukurumidza asi kwenguva pfupi nekugadzira okisijeni yemelanin iripo.
Njodzi: Dzinobatanidzwa nekukwegura nguva isati yakwana (makwinya) uye njodzi yakakura yekenza yeganda yenguva refu (melanoma).
Mwaranzi yeUVB (1–5% yezvinobuda):
Chinangwa: Kuchinja pamusoro peganda kuti riwedzere kutsvuka kweganda zvishoma nezvishoma asi kwenguva refu nekukurudzira kugadzirwa kwe melanin itsva.
Njodzi: Dzinokonzera kupiswa nezuva uye dzinokonzera kukuvara kweDNA.
Njodzi huru dzekusviba UV pamubhedha:
Gomarara reganda: WHO inoisa mibhedha yekutsvukisa ganda muboka rekutanga sezvinhu zvinokonzera kenza, zvakaita sefodya.
Kuchembera nguva isati yakwana: UVA inoputsa collagen, zvichikonzera makwinya uye mavara ezuva.
Kukuvara kwemaziso: Kupfeka magogorosi ekudzivirira kwakakosha kudzivirira cataract.
Mibhedha yekutsvukisa ganda zvichienzaniswa nechiedza chezuva chemazuva ose
Chinhu Chakakosha: Mibhedha yekuchenesa ganda kana tichienzanisa nechiedza chezuva chemazuva ese
Kusimba kweUV: simba rakapetwa katatu kusvika gumi neshanu kupfuura zuva remasikati.
Zvinosiyana zvichienderana nenguva/mamiriro ekunze.
Chiyero cheUVA/UVB: chikamu chikuru cheUVA (UVB shoma) zvichienzaniswa nechiyero cheUVA/UVB chakaringana.
Nguva yekuratidzwa: maminetsi gumi kusvika makumi maviri ekudzidza uchienzanisa nekuratidzwa zvishoma nezvishoma kwemaawa ari panze.
Mimwe mibhedha inoshandisa UV 'yakachengeteka' here?
Kwete, kunyange zvazvo mibhedha mitsva ichiti 'haina njodzi yakanyanya' (semuenzaniso mibhedha yeUVA ine pressure yakakwira), kusviba kwese kweUV kune njodzi dzekenza. Kuti uwane chiedza chakachengeteka, funga nezve:
- Spray tans (yakavakirwa paDHA, isina UV)
- Mafuta ekuzvichenesa ega uye mousse
- Kurapa nechiedza chitsvuku (kwete kushandisa UV, kune hutano hweganda).
Pfungwa huru:
Mibhedha yekutsvukisa ganda inoshandisa chiedza cheUV chakasimba uye ine njodzi kupfuura zuva. Vanachiremba veganda vanokurudzira zvikuru kuti usashandise chiedza ichi. Kana ukasarudza kutsvukisa ganda, gara uchipfeka magirazi ekudzivirira ganda uye deredza nguva yako yekutsvukisa ganda.
