Amashanyarazi

Icyuma cya flat-bulb nigisubizo cyigiciro cyinshi, gikora neza kandi kirwanya ruswa kubisabwa kugirango bikomere. Ibyiza byingenzi birimo imbaraga zidasanzwe kubipimo byuburemere bitanga imbaraga zo guhangana nuburemere buke ugereranije nuburinganire cyangwa inguni.
Impande zegeranye zerekana ibyuma byerekana ibyuma bisobanura ko bidakenewe gusya mbere yo gushushanya, kubika igihe n'amafaranga mugihe cyo guhimba. Kwangirika kw'irangi no kubaka imyanda yangirika nabyo biragabanuka, byongera ubuzima.
