Nsalu yaubweya ndi yofewa modabwitsa ndipo imabwera mumitundu yosiyanasiyana yowoneka bwino. Chovala chopanda ubweya chidzapanga nsalu yofunda komanso yogwira ntchito; komabe, kupanga makonda anu mpango mpango ndiGalvo laser chosema makinazimapangitsa mpangowo kukhala wofunikira m'nyengo yozizira komanso mawonekedwe afashoni. Monga bwenzi labwino kwambiri m'nyengo yozizira, mpango ndiye kusankha kotentha kwambiri kuti anthu aziyenda. Laser cholemba mpango kulola kalembedwe ndi kutentha kukhala pamodzi.
Kujambula kwa laser pansalu, kusalumikizana ndi laser, sikungawononge kukhudza kosalala komanso kofewa kwa mpango wonyezimira. Nthawi yomwe mumakhudza, mumamva bwino kwambiri, ndikuwonjezera kukhudza kwachifundo kuchisanu chozizira.
Mitundu yodzaza ndi mapangidwe okongola a laser amasinthidwa kukhala kutentha pakhosi. Ngakhale kuzizira kwachisanu kumalowa m'mafupa, akhoza kukupatulani kuzizira kupyolera mu kutentha.
Zovala zimakhalanso ngati zodzikongoletsera m'nyengo yozizira. Zovala zamitundu yosiyanasiyana zimafanana ndi malupu amitundu yosiyanasiyana, okhala ndi mfundo pakhosi, kapena amatha kuvala mosasamala, zomwe zimatha kulumikizana bwino ndi zovala. Ndikungoyembekeza kuti pa tsiku lozizira kwambiri, nsalu yojambulidwa ndi laser idzakulolani kuti mukhale ndi ndakatulo yotentha kwambiri m'nyengo yozizira kwambiri.
