Igihe ugura, uzokenera kumenya ubushobozi wipfuza kandi uhitemwo hagati y’ibikoresho canke ata bikoresho bishingiye ku vyo ukunda. Ku bikoresho bimwe bimwe - ibikoresho vyo gufata ibinyobwa bishushe. Ivyo bishushanyo bitagira amaboko biratanga ishusho y’agaciro gatoyi kandi y’iki gihe. Mu buryo butandukanye n’ibirahuri bisanzwe, ibirahuri vy’ibara ry’agahama birimwo nibura 5% vy’ivyuma vy’ibara ry’agahama. Iryo hinduka ry’imiti rituma rishobora kwihanganira uguhinduka kw’ubushuhe bwinshi cane.
Abakoresha benshi barahuye n’ico kibazo igihe bakoresha ibikombe vy’ibirahuri: Hariho amazi akanye mu gikombe, ariko bashaka amazi ashushe. Iyo basutse amazi akanye asohoka hanyuma bagashira amazi atetse, ibirahuri birasaduka. Ivyo ni kubera ko ikirahuri kitashobora guhangana n’uguhinduka kw’ubushuhe. Ibikombe binini vy’ibirahuri vy’ibirahuri bigufasha guteka icayi canke ikawa ataco ushizemwo, canke gusuka amazi mu gikombe c’ibitoke. Ni vyiza - bishingiye ku guhinduka kw’ubushuhe, rero nta n’imwe ihagaritse umutima ku bijanye no gusaduka canke guca mu gihe co gukoresha. Ubushobozi bwabo bwinshi buratuma baba bwiza cane ku nzu. Igikombe gishimishije ni ikintu gihambaye cane ku bakunzi b’ibinyobwa vya misi yose, haba ari ugusuka ikawa{7}} kuba ikawa canke icayi gishushe, ibinyobwa vy’urubura, ibinyobwa vy’umwihariko n’ibinyobwa vy’umukara, canke amasupu ashushe n’ibinyobwa.
Ibikombe vyinshi vy’ibirahuri birakomeye cane kandi birasha cane-kubaho kuruta ibirahuri bisanzwe, ariko ivyo ntibisigura ko ataco bimaze ku matonyanga. Urabe maso ku bijanye n’ibisebe n’ibikomere mu gihe co gukoresha, cane cane abana. Imisi yose ushire ikirahuri mu kibanza gitekanye kugira ngo ntukomangane n’ugumenagura. Si ngombwa ngo umuntu agire ibicu canke apfutse inyuma yo gukaraba ku musi canke amaze gufata ibinyobwa vy’aside. Ibikombe binini vy’ibirahuri vy’ibirahuri ni - bitari vyo kandi bitagira amazi bifise amazi. Ni akamoto-kudashobora gusukurwa, kworoha gusukurwa, gutungana ibidukikije, no kugira amagara meza. Ni uburyo buramba cane bwo gukoresha amapulasitike ashobora gukoreshwa, bigatuma umuntu yumva ko ari muhira, ibiro, eka mbere no kwisamaza. Ubushobozi bwayo bisigura ko butazoshobora gusesa imiti itera ingorane mu binyobwa bishushe, bikaba bituma ari amahitamwo meza ku bana b’inzoya, abagore batwite, n’abafise ingorane z’amagara.
Igikoni c’ibara ry’agahama gikoreshwa mu bikombe bininibinini vy’ibirahuri vy’ibara ry’agahama si ibirahuri bisanzwe; ni ikirahuri kidasanzwe kizwi cane kubera ubushobozi bwayo budasanzwe n’ubushobozi bwo guhangana n’ubushuhe. Ariko rero, birahambaye kumenya ko naho bishobora guhangana n’ubushuhe bwinshi, kwirinda gushusha ibikombe vy’ubusa ku bishashi vyuguruye canke ku binogo vy’amabuye. Ubushobozi bw’uguhungabana kw’ubushuhe ntibutuma umuntu ashobora guhangana n’umuriro. Irinde ibintu bisongoye n’amatonyanga; kabiri - ibikombe vy’uruhome biragoramye cane kuruta - uruhome. Irinde gukoresha cane, nk’impuzu zo gusukura kugira ngo ntube umese ku ruhande. Kugereranya ibirahuri bibiri, bisanzwe ni nk’igice c’isokoroti ikomeye, kwihutisha no guhindura iyo umuntu ashushe, mu gihe ibikombe binini vy’ibirahuri vy’ibirahuri vy’ibara ry’agahama ari nk’icuma gikomeye, kiguma ari nk’aho kidatera.
