Iyo abantu batangira gukora irangi mu nzu, kimwe mu bibazo bikunze kubazwa ni iki:
"Ni iki gipimo cya UV kiri mu gikoresho cyo gushushanya uruhu?"

Igipimo cy'imirasire ya UV hanze gipima imbaraga z'imirasire ya UV y'izuba. Ariko ahantu ho gushushanya ibara ry'umuraba hakoreshwaamatara y'ubukorano ya UV, bishobora gutanga urugero rw'imirasire ya UV ruri hejuru cyane kurusha urumuri rw'izuba rusanzwe. Gusobanukirwa uburyo UV ifite imbaraga zo gukaraba mu buryo bw'umwimerere bishobora kugufasha gukaraba mu buryo bwizewe no guhitamo ibikoresho byiza.

Iyi mfashanyigisho isobanura icyo igipimo cya UV gisobanura, uburyo ibitanda byo gusiga ibara ry'izuba bigereranywa n'izuba, itandukaniro riri hagati y'ubwoko bw'ibitanda, n'uburyo bigezwehoUburiri bwo gushushanya ku ruhu bwa Megizikekugenzura imirasire ya UV kugira ngo ikoreshwe neza kandi ikore neza.

Igipimo cya UV (UVI) ni iki?

ItsindaIgipimo cya UVni igipimo gisanzwe gikoreshwa mu gupima ubukana bw'imirasire ya ultraviolet ituruka ku zuba.
Irimo kuva kuri:

• 0(hasi cyane) kugeza kuri

• 11+(bikabije)

Igipimo cya UVI cyo hanze gihinduka bitewe na:

• Isaha y'umunsi

• Igihembwe

• Ubutumburuke

• Ikirere

UVI ya6–7bifatwa nk'aho ari byinshi.
UVI ya10–11+bifatwa nk'aho ari hejuru cyane cyangwa bikabije.

None se, ni iki gipimo cya UV kiri mu gitanda cyo gukaraba?

Igipimo cya UV kiri mu duce two gutwikiraho ibara ry'umuraba kiratandukanye, arikoUburiri bwinshi bwo gusiga ibara ry'uruhu bukora hagati ya UVI 10 na UVI 15.

Amwe mu madirishya asohora umusaruro mwinshi ashobora kugera ku rwego rungana naUVI 20 cyangwa hejuru yayo, bitewe n'ubwoko bw'itara n'ubukana bwaryo.

Mu yandi magambo:

Igipimo cy'imirasire ya UV ku gitanda cyo kurarana gishobora kuba gikomeye kuri 2–4× kurusha izuba ryo mu gihe cya saa sita.

Iyi ni yo mpamvu uburiri bwo gusiga ibara ry'uruhu butanga umusaruro vuba—kandi ni yo mpamvu igihe cyo kugaragara kigomba kugenzurwa neza.

Kuki imirasire ya UV mu byo kuraramo biba bikomeye?

Uburiri bwo gusiga ibara ry'uruhu bukoresha amatara yihariye yagenewe:

• Gukangura ikorwa rya melanin neza

• Tanga uburyo bwo kureba niba hari imirasire ya UV ishoboka

• Tanga ibisubizo bihoraho ku ibara ry'uruhu

Zakozwe kugira ngo zikoreshwe mu gushyushya vuba, bivuze ko urugero rw'imirasire ya UV ruri hejuru cyane ugereranyije n'urugero rusanzwe rwo hanze.

UVA na UVB mu gitanda cyo gukaraba

Igipimo cya UV ntikigaragaza igipimo cyaUVA to UVB, ibyo bikaba ingenzi ku bisubizo byo gushya kw'ibara ry'uruhu.

UVA (90–95%)

• Icengera cyane

• Ikora ibara ry'umuhondo rimara igihe kirekire

• Nta mahirwe menshi yo gushya

• Yihutisha gusaza k'uruhu iyo ikoreshejwe cyane

UVB (5–10%)

• Itera imbere ikorwa rya melanin

• Irema "ibara ry'ibara ry'ibanze"

• Bishobora gutera ubushyuhe bw'izuba

Imitako itandukanye ikoresha ingano zitandukanye za UVA/UVB bitewe n'umusaruro wifuza.

Ubwoko bw'ibitanda byo mu ruhu n'ubukana bwabyo mu mirasire y'izuba

1. Ibitanda byo gusiga ibara ry'uruhu bifite umuvuduko muke

• Ururenda rwo hejuru rwa UVB

• Igipimo cya UV gisanzwe:UVI 10–15

• Ni byiza mu kubaka tan yo hasi

• Ingaruka nyinshi zo gushya

2. Ibitanda byo gusiga ibara ry'uruhu bikoresha umuvuduko mwinshi

• Ahanini ni UVA

• Igipimo cya UV gisanzwe:UVI 12–20+

• Itanga ibara ryijimye kandi ryijimye vuba

• Ingaruka zo gushya nkeya

• Bisaba amasomo make ku cyumweru

ByinshiAbanyamerikaIbitanda bifite umuvuduko mwinshi biri muri iki cyiciro, byagenewe gutanga ibara ryiza hamwe no kubona iminota mike.

Uburyo ibitanda byo mu bwoko bwa Merican Tanning Bicunga Ubukana bwa UV mu Mutekano

Ikigo cya Amerika gishinzwe ikoranabuhanga rya UV kugira ngo kirebe ko abagikoresha bahinduka ibara ry’umutuku neza nta kwibasirwa n’ibintu bitari ngombwa.

✔ Umusaruro wa UV ugenzurwa neza

Ibitanda bya Amerika bikoresha ikoranabuhanga ry’amatara ahamye ririnda kuzamuka gutunguranye cyangwa gukwirakwira kwa UV mu buryo butaringaniye.

✔ Imiterere myiza ya UVA/UVB

Byakozwe kuri:

• Ongera ubushobozi bwo gusiga ibara ry'uruhu

• Kugabanya ibyago byo gushya

• Tanga ibara ryimbitse kandi rimara igihe kirekire

• Bisaba igihe gito cy'imyitozo

✔ Igihe cyo Kwiyerekana mu Buryo Bw'ubwenge

Ibipimo by’umutekano bihuriweho bigabanya igihe cyagenwe cyo kureba urumuri bitewe n’ubukana bw’urumuri.

✔ Sisitemu z'amatara afite umuvuduko mwinshi

Itanga UVA ikomeye ku ibara ry'umutuku ryihuse, bigabanya ubwiyongere bwa UVB muri rusange.

✔ Uburiri bw'urumuri rutukura + UV Hybrid (Ntabwo ari ngombwa)

Kongeramo urumuri rutukura bifasha:

• Kugabanya ububyimbirwe

• Kunoza imiterere y'uruhu

• Shyigikira inzira nziza yo gusiga ibara ry'uruhu

Izi mvange z'uburiri zitanga ubwiza n'ibyiza byo kwisiga icyarimwe.

Ese igipimo cy’imirasire ya UV kiri hejuru ni cyiza kuri Tanning?

Si ngombwa.

UVI iri hejuru = kwihuta kw'ibara ry'uruhu

UVI iri hejuru = gushya vuba (niba bitakingiwe)

Intego niikwirakwizwa ry'imiraba ya UV rigenzurwa, ntabwo ari imbaraga ntarengwa.

Ntabwo ukeneye igipimo cy'imirasire ya UV kiri hejuru cyane—ukeneyeurwego rukwiye ku bwoko bw'uruhu rwawen'igihe bizamara.

Uburyo bwo Gusiga Ibara ry'Umutuku mu Mutekano Ukoresheje UV nyinshi

1. Tangira n'amasomo magufi

Cyane cyane niba ufite uruhu rworoshye cyangwa rworoshye.

2. Irinde kwisiga ibara ry'uruhu buri munsi

Uruhu rukeneye amasaha 24-48 kugira ngo rukire.

3. Kurikiza amabwiriza y'uburyo bwo kugaragara kw'ahantu hatwikiriye uruhu

Buri gitanda gifite igihe ntarengwa—ntukigere ukirenza.

4. Koresha amavuta yo kwisiga mu nzu

Bifasha uruhu kwihinduriza vuba kandi bigakomeza kugira ubushyuhe.

5. Ambara indorerwamo zo kwirinda buri gihe

Kwangirika kw'amaso ni ukw'iteka ryose kandi ubushyuhe bwa UV hafi y'isura yawe ni bwinshi.

Igipimo cya UV mu Gitanda cyo Guta Izuba ugereranyije n'Umucyo w'Izuba (Imbonerahamwe yo Kugereranya)

Ibitanda byo mu nzu bitanga urumuri rw'imirasire ya UV ihoraho, bitandukanye n'izuba rihindagurika umunsi wose.

Umwanzuro

Igipimo cya UV kiri mu gikoresho cyo gusiga ibara ry'umuhondo gikunze kubahagati ya UVI 10 na 20, bitewe n'ibikoresho n'ubwoko bw'amatara—bikomeye cyane kurusha urumuri rw'izuba rusanzwe. Ubu bushyuhe bugenzurwa nibyo bituma uburiri bwo gusiga ibara ry'umuhondo bugira akamaro ariko kandi bisaba igihe gikwiye n'uburyo bwo kwirinda.

IgezwehoUburiri bwo gushushanya ku ruhu bwa Megizikekongera umutekano binyuze mu:

• Kugenzura ubukana bwa UV

• Gukoresha neza UVA/UVB

• Kugabanya ibyago byo gushya

• Gutanga ibara ryimbitse ry'izuba hamwe n'igihe gito cyo kuribona

Usobanukiwe uburyo imbaraga za UV zikora no gukoresha ibikoresho byiza, ushobora kugira ibara ry’umutuku mu buryo butekanye kandi ukabona umusaruro mwiza kandi urambye.
