Mbere yo kuyambara, ibuka kugenzura itariki ntarengwa iri ku icupa. Kubera ko amacupa menshi yo kwisiga ku zuba afite itariki ntarengwa. Iyo iyo tariki irangiye, ntabwo dushobora kwemeza neza uburinzi butanga.
Muri rusange, ibikoresho bisiga izuba bigomba kugumana ubuziranenge bwabyo bw’umwimerere kugeza ku myaka itatu nk'uko amategeko abiteganya. Rero, niba icupa ryawe ritarengeje imyaka itatu, nta kibazo kurikoresha. Ariko niba icupa ridafite itariki ntarengwa, andika itariki wariguzeho ku icupa ufite ikimenyetso gihoraho. Muri ubwo buryo, uzamenya neza igihe ushobora kurikoresha. Nanone, ni byiza kubika amacupa asiga izuba ku bushyuhe bw'icyumba. Niba ubonye impinduka mu ibara, impumuro, cyangwa imiterere yaryo, ni byiza kurijugunya ukagura icupa rishya. Mbere yo kugura icupa rishya, reka tuvuge ku bintu bimwe na bimwe bizagufasha guhitamo amavuta akurinda izuba akubereye.
Ni iki gikoresho cyiza cyo kwisiga izuba kigomba kuba kirimo?
Hari ibintu bike by'ingenzi ugomba kuzirikana mu gihe uhitamo amavuta yo kwisiga akingira uruhu rwawe azagufasha cyane. Reka tubirebe kimwe kimwe.
1. Ese handitseho "broad-spectrum"?
Ikintu cya mbere ugomba kureba mu gihe uhitamo amavuta akingira izuba ni ukumenya niba ari "afite imiterere migari." Muri make, aya mavuta arinda uruhu rwacu imirasire ya UVA na UVB ituruka ku zuba.
- Imirasire ya UVA: Iyi yinjira cyane mu ruhu kandi ni yo mpamvu nyamukuru ituma uruhu ruhinduka iminkanyari kandi rugasa n'urwashaje kurusha uko ruri.
- Imirasire ya UVB: Iyi ni yo ituma uruhu rushya, rugatukura, kandi rukababara.

Ariko ibi ntabwo "birinda amazi", ahubwo "birinda amazi". Ibi bivuze ko ubushobozi bwabyo buzagabanuka nyuma y'igihe runaka. Kubwibyo , ni ngombwa kongera gukoresha amavuta yo kwisiga izuba nyuma yo kuva mu mazi cyangwa nyuma yo guhanagura ibyuya.
Ubwoko bw'imiti irinda izuba n'ibyo irimo
Indabyo zirinda izuba zishobora kugabanywamo ubwoko bubiri bw'ingenzi: imiti n'imyunyungugu . Ibikubiye muri ibi byombi n'imikorere yabyo biratandukanye.
