Igihe kingana iki mu zuba kingana n'igihe cyo gusinzira mu jisho?

Abantu benshi bibaza uburyo igihe cyo kuryama ku zuba kigereranywa n'igihe cyo kwihisha izuba mu buryo busanzwe. Ese iminota 10 mu zuba ku zuba ni kimwe n'isaha imwe? Igisubizo si cyo nyacyo, ariko ubushakashatsi n'amabwiriza y'ubuvuzi bw'uruhu atanga igereranya ry'ingirakamaro rishingiye kuUbukana bwa UV n'ubwoko bw'ikwirakwizwa.

Gusobanukirwa iri gereranya bishobora kugufasha gufata amahitamo meza mu gihe cyo gusiga ibara ry'uruhu.

Impamvu ku zuba no ku buriri bwo kwisiga bitameze kimwe

Imirasire y'izuba n'imitako y'izuba byombi bisohora imirasire ya ultraviolet (UV), ariko bitandukanye muri ibi bikurikira:

• Umucyo w'imirasire y'imirasire ya UV(UVA vs UVB)

• Ubukana n'ubudahinduka

• Ibintu bifitanye isano n'ibidukikije

Izubaisohora UVA na UVB, imbaraga zayo zigahinduka umunsi wose.
Ibitanda byo gusiga ibara ry'uruhugutanga dose igenzurwa ariko irimo imbaraga nyinshi, cyane cyaneUVA (95–99%).

Kubera iyo mpamvu, ibitanda byo gusiga ibara ry'uruhu bishobora gushyira uruhu rwawe ku rugero rwo hejuru rwa UVA mu gihe gito.

Igereranya Rusange: Igihe cyo Kuryama ku Cyuzure vs Igihe cyo Gufata Ibara ry'Umutuku

Nubwo ingano nyayo itandukana, igereranya rikunze kuvugwa ni iri:

Iminota 10–15 mu gitanda cyo gusiga ibara ry'uruhu ≈ amasaha 1–3 ku zuba rya saa sita

Iki kigereranyo gifata ibi bikurikira:

• Uburiri busanzwe bwo gusiga ibara ry'uruhu mu bucuruzi

• Izuba ryo ku manywa mu kirere kirimo imirasire myinshi y'izuba

• Ubwoko bw'uruhu buri hagati y'ubwoko bubiri

Amwe mu mabaraza yo gusiga ibara ry’umuvuduko mwinshi ashobora gutanga ingero zikomeye za UVA mu gihe gito.

Ibintu Bihindura Igereranya

Hari ibintu byinshi bigira ingaruka ku kuntu igihe cy'izuba kigereranywa n'igihe cyo gukoresha mu gusiga irangi:

1. Ubwoko bw'uburiri bwo gusiga ibara ry'uruhu

• Ibitanda bifite umuvuduko muke: Imyitozo miremire, imbaraga ziringaniye

• Ibitanda bifite umuvuduko mwinshi: Imyitozo migufi, umusaruro mwinshi cyane wa UVA

2. Isaha y'umunsi

Izuba ryo ku manywa (10:00 AM–4 PM) rirakomeye cyane kurusha izuba ryo mu gitondo cyangwa nyuma ya saa sita.

3. Ubwoko bw'uruhu

Uruhu rwiza rushya vuba kandi rufata imirasire ya UV mu buryo butandukanye n'uko uruhu rwijimye rubyibushye.

4. Ubumenyi bw'isi n'ibihe

Urugero rw'imirasire y'urumuri rw'izuba ruri hejuru hafi ya equator, mu misozi miremire, no mu mezi y'impeshyi.

Ni iki gitera kwangirika k'uruhu cyane?

Kwicira izuba n'uduti two kwisiga byangiza uruhu, arikoibitanda byo gusiga ibara ry'uruhu bishobora kwangiza UVA nyinshi mu gihe gito.

Ingaruka zishobora kubaho zirimo:

• Gusaza kw'uruhu vuba

• Gusenyuka kwa kolajeni

• Gupima ibara ry'uruhu

• Ubwiyongere bw'ibyago byo kurwara melanoma n'izindi kanseri z'uruhu

Imiryango y'ubuzima ishyira ahantu ho gusiga ibara ry'uruhu mu byiciroitera kanseri, bisa no kwibasirwa n'izuba rikabije.

Ese hari uburyo bwo gusiga ibara ry'uruhu mu buryo "butekanye"?

Nta rugero rwiza rwose rwo gusiga ibara ry’urumuri rw’imirasire y’izuba. Ndetse no kuryamaho igihe gito byongera kwangirika k’uruhu uko igihe kigenda gihita.

Ku bashaka kugaragara nk'umutuku:

• Ibikoresho byo kwisiga uruhu bidakoresha izubaitanga ibara ridafite imirasire ya UV

• Ubuvuzi bw'urumuri rutukuraishyigikira uruhu rusa neza rudakoresheje imirasire ya UV cyangwa uruhu rudakoresha imirasire ya ultraviolet

Ibitekerezo bya nyuma

None se, igihe kingana iki umuntu amara ku zuba kingana n'igihe cyo kwisiga ibara ry'umuhondo?

Muri rusange,Igihe gito cyo kuryama ku zuba gishobora kungana n'amasaha yo kwihisha ku zubacyane cyane mu bijyanye n'imirasire ya UVA. Nubwo ahantu ho gusiga ibara ry'umuhondo hashobora gusa n'aho hagenzurwa neza, ntabwo ari ahantu hatekanye kurusha imirasire y'izuba karemano.

Kugabanya imirasire y'izuba ni bwo buryo bwiza bwo kugira ubuzima bwiza bw'uruhu igihe kirekire.

Ibibazo Bikunze Kubazwa

Ese kumara iminota 10 uri mu gitanda cyo kwisiga ibara ry'uruhu ni kimwe no kuba uri ku zuba umunsi wose?
Si umunsi wose, ariko ishobora kungana n'amasaha menshi y'izuba rikomeye rya saa sita.

Ese ahantu ho gusiga ibara ry'izuba hatanga vitamine D nk'izuba?
Uduce twinshi two gushushanyaho uruhu dusohora UVB nke cyane, bityo umusaruro wa Vitamine D ukaba muke.

Ese uburiri bwo gusiga ibara ry'izuba bushobora gutera gusaza vuba kurusha izuba?
Yego. Ubwinshi bwa UVA bushobora kwihutisha iminkanyari no gusaza k'uruhu.
