Chifuwa cha nkhuku ndi dzina lodziwika kwambiri la matendawa, mu mankhwala omwe amadziwika kuti hemeralopia (osamvetsetseka malingaliro owonetseredwa kuti awonongeke pang'ono). Munthu amene akudwala matendawa, amawona bwino kwambiri madzulo ndi usiku, koma masana, maonekedwe ake amatha.
Zikuwoneka - nkhuku zili kuti? Chowonadi ndi chakuti mphamvu ya munthu, ndi yina lirilonse, kuthana ndi zikhalidwe ndi kuuniyanitsa kosiyana zimadalira zinthu zowonongeka za retina: ndodo ndi cones. Nkhonozi zimayang'ana masomphenya a tsiku, ndi timitengo, zomwe zimakhala ndi photosensitivity - usiku. Mu nkhuku, zimamatira mu retina zili pafupi, ndipo potero dzuwa litalowa amakhala kwenikweni akhungu. Chifukwa chaichi, matenda omwe anthu amafooka ndi masomphenya a usiku, ndipo amatchedwa khungu la usiku.
Zifukwa za usiku wakhungu
Matendawa amayamba chifukwa cha kuphwanya chiŵerengero pakati pa nkhono ndi ndodo mu diso la munthu, kuchepetsa chiwerengero cha ndodo kapena zovuta zomangamanga za mawonekedwe awo, komanso chifukwa cha kusowa kapena kusokoneza kusinthanitsa kwa mtundu wa rhodopsin, womwe uli m'mitengo.
Ndizozoloŵera kusiyanitsa mitundu itatu ya usiku wakhungu:
- kusonkhanitsa;
- Chofunika;
- zizindikiro.
Kawirikawiri ndi khungu lofunika usiku. Matendawa amatha kupweteka chifukwa cha kusowa kwa zakudya m'thupi, chifukwa chosowa mavitamini, poyamba - vitamini A. Kuonjezera apo, ikhoza kuyambitsa matenda a chiwindi, matenda a chiwindi, kutopa kwathunthu kwa thupi, kutengeka kwa poizoni zosiyanasiyana.
Khungu lachidziwitso usiku limayamba chifukwa cha matenda a maso, monga glaucoma, retinitis pigmentosa, digiri yapamwamba myopia.
Umoyo wakhungu wa usiku umayamba chifukwa cha matenda ena, makamaka, matenda a retinitis kapena ma Asher.
Zizindikiro za khungu usiku
Ndi khungu la nkhuku, maso amachepa kwambiri mu zinthu zochepa. Kuwongolera kwake kumachepa, zinthu zimawoneka zosasunthika, zosaoneka bwino, malo owonera amachepa, malingaliro a mtundu akuphwanyidwa. Kawirikawiri malingaliro oyenera a mtundu wa buluu amavutika, kapena palibe masomphenya a mtundu nthawi zonse madzulo ndi usiku. N'zotheka kuti maonekedwe asadayang'ane panthawi ya kusintha kuchokera ku chipinda chowala mpaka mdima ndi kumbuyo.
Kodi mungachite bwanji khungu la usiku?
Tiyenera kukumbukira kuti chithandizo cha usiku wakhungu chimadalira mtundu wake ndi zomwe zinayambitsa izo.
Matenda a mtundu wofunikira amadzipangitsa mosavuta kuchipatala. Popeza kawirikawiri ubweya wausiku umenewu umayamba chifukwa cha kusowa kwa vitamini A, ndiye kuti kuthetsa matendawa kumamwa mavitamini.
Ngati vuto la vitamini A lidayamba chifukwa cha kumwa mankhwala omwe amatsutsana nawo (mwachitsanzo, quinine), mankhwala ayenera kuchotsedwa nthawi yomweyo ndipo kudya mavitamini kuyenera kuchitidwa mwamsanga. Usiku ukhungu umachitika chifukwa cha matenda a chiwindi, matenda ndi zina zotero, matenda akuluakulu amachiritsidwa makamaka.
Njira yokha yothetsera matendawa ndi zakudya zabwino. Muyenera kudya kaloti, kabichi, zipatso za citrus, timadziti tatsopano, chiwindi cha nsomba ndi zinyama.
Ndi chizindikiro cha hemorrhagia, choyamba chitani matenda openyetsa maso. Izi zingakhale kusankha magalasi olondola komanso kugwiritsa ntchito mankhwala osokoneza bongo kwa myopia. Kugwiritsa ntchito mankhwala ndipo, ngati n'koyenera, opaleshoni ya cataracts kapena glaucoma.
Maonekedwe a usiku akhungu sagwirizana ndi chithandizo, ndipo kumakhala kuchepa nthawi zonse m'mawonedwe a madzulo.
